Gleanings of the Week Ending May 18, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

25 Years, 25 Images – Celebrating twenty-five years since the launch of NASA Earth Observatory (EO) on April 29, 1999 and the EO website with a slideshow!

Insurance Companies: Consider Climate Risk Events As “Constant Threats” - Up until recently, most people weren’t concerned with how their ability to be insured would change — until catastrophic climate disasters began to wreak havoc on communities around the country. I am very glad I don’t own property in Florida or south Texas or California!

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

Our Missouri Yard – May 2024

May is when our yard becomes lush with new growth --- with the warmer temperatures and plentiful rain. The plants love it.

The wildflower garden that I started last year has returned either from reseeding or coming up from last year’s roots. I cleared some more rocks/landscaping cloth around the edges and planted more seeds there but they haven’t emerged yet.

The seeds I planted on the sunny side under the pine tree are coming up! I am going to cut down the pokeweed growing around the perimeter to make sure the area doesn’t become too shady.

The fragrant sumac I planted last year is back with lots of new leaves – like the bush beside it (which I haven’t identified but I like the leaves).

The alliums are blooming in the area outside the flower bed near my office window. I am converting the area from grass/moss to other things. Right now, it is thick with alliums, daffodil leaves, violets, and some weeds/grass. The spikenard I bought last fall has returned but is still relatively small. The stainless-steel iris I bought for my mother (Mother’s day 2023) is now in that area too.

The glass birdbath I carefully packed and moved from Maryland is now out and visible from one of my office windows (where I sit to make Zentangle tiles). I haven’t noticed any birds finding it yet. The stainless-steel spider mum is under a nearby pine…also an area I am converting from grass.

There are some holes in the turf of our yard where plants have come up. Sometimes I let them grow. The most successful area is lambs ear to the side of our house by the gate to our backyard. I hope that it eventually joins with some lambs ear that is growing in the corner made by the fence and the house (it has a small pokeweed growing with it). It has many bloom stalks. I’ll let them make seeds then cut them – hope the plant continues to expand via roots too.

On the other side of the fence is some more lamb ear and showy golden rod that I bought last fall. Hopefully the goldenrod will get enough sun to bloom well in that spot.

The hens and chicks are multiplying in the front rock garden.

And the kousa dogwood is full of blooms.

We have been mulching leaves and grass into the yard…and frequently see small mushrooms. They’re decomposing all that plant debris into nutrients the roots of the plants can absorb! I love to see evidence that the yard is vibrant with life other than just grass; we are succeeding in making it less a monoculture with shallow roots (i.e. turf grass).

Gleanings of the Week Ending May 11, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

A new way to quantify climate change impacts: 'Outdoor days' - Noting the number of days per year that outdoor temperatures are comfortable enough for normal outdoor activities. In the North, in a place like Russia or Canada, you gain a significant number of outdoor days. And when you go south to places like Bangladesh or Sudan, it's bad news. You get significantly fewer outdoor days.

Is filtered water healthier than tap water? - Water filters, it seems, are having a heyday – particularly in North America, Europe, and China. I was a little surprised that the article did not mention microplastics in water – even in countries that have relatively high standards for their water supplies.

Baltimore’s Toxic Legacies Have Reached a Breaking Point – “Normal” southwest of the collapsed Frances Scott Key Bridge in Baltimore…one of the most polluted places in the U.S. – a different perspective on the bridge collapse.

European ruling linking climate change to human rights could be a game changer — here’s how - On 9 April, the European Court of Human Rights delivered a groundbreaking ruling: states are obliged to protect their citizens from the threats and harms of climate change. And in that regard, judges said, Switzerland’s climate action has been inadequate. Without prescribing specific years or percentage reductions, the ruling set out how a nation can show it is compliant. It must set out a timetable and targets for achieving carbon neutrality, and pathways and interim targets for reducing greenhouse-gas emissions. Measures must be implemented in a timely, appropriate, and consistent manner. Governments must also provide evidence that they have complied with targets, and update targets regularly.

Positive perceptions of solar projects - A new survey has found that for U.S. residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin.

18th-Century Foundation Uncovered at Colonial Williamsburg – Even in much studied areas, there are still new things to discover!

Metabolic health before vaccination determines effectiveness of anti-flu response - Metabolic health (normal blood pressure, blood sugar and cholesterol levels, among other factors) influences the effectiveness of influenza vaccinations….even in people with obesity which the vaccine had previously been documented as being less effective.

The environmental cost of China's addiction to cement - Today, China still accounts for just over half of the world's total annual 4.1bn tons of cement production (52%) – followed by India (6.2%), the EU (5.3%) and the US (1.9%). Little of that cement produced in China is exported. In 2020 the country used an estimated 2.4 billion tons of cement, 23 times the amount used in the US in the same year.

Teotihuacan's Pyramids Damaged by Ancient Earthquakes – Damage from megathrust earthquakes at the site between about AD 100 and 600: fracturing and dislodging of large masonry blocks used to construct the buildings, as well as chipping of blocks that comprised the pyramids' outer stairs.

Mini-colons revolutionize colorectal cancer research - Scientists have combined microfabrication and tissue engineering techniques to develop miniature colon tissues that can simulate the complex process of tumorigenesis outside the body with high fidelity, giving rise to tumors that closely resemble those found in vivo….offering a new path to research colon cancers and their treatment.

The Natural History of British Birds

This week’s eBooks are the 10 volume The Natural History of British Birds by Edward Donovan. They were first published in the late 1700s and are available on Internet Archive. The author did not travel but described and illustrated species based on collections of other naturalists.  It is obvious in some of the illustrations that he never saw the living bird! Still – the illustrations were my motivation to browse the books – thinking about how the numbers of these birds are reduced from when he worked…and how this author’s books are a natural history snapshot of birds (and insects) that were collected/available to him.

Out and About with Company

When my sister and brother-in-law were visiting – stopping for a few days at a RV park near us before they continued on their month long travels – we enjoyed the botanical gardens and the zoo, then decided on a less active day starting with brunch at my house (I made a ‘full oven’ of food: egg casserole, chunks of seasoned new potatoes, and pumpkin bread) followed by a walk around the Springfield Art Museum and then the Springfield Conservation Nature Center.

The art museum was opening their Art in Bloom event – with the fashion component being the main part available for viewing. My favorite was the creation that was inspired by the hallway long tilted sky – probably my favorite piece in the museum!

Of course, there were plenty of other things to enjoy in the museum – other fashion and art works. I’ve picked some of my favorite views from the pictures it took.

Then we were off to the nature center…not for a hike (one of my guests was having back problems) but for the center itself. The turtle tank was being renovated so there were two large snapping turtles in a tank that was too small for them long term but offered views from two sides. It was a great photographic opportunity.

And then they headed off to prepare for the next leg of their trip.

Dickerson Park Zoo – April 2024

My first trip of the season to the Dickerson Park Zoo was back at the end of March (post 1, post 2); my second was near the end of April when my sister and brother-in-law visited. Like the first visit, there were lots of peacocks wandering through the zoo; this time there were peahens too and there were some instances where it looked like the birds were either already incubating eggs…or getting a ‘nest’ ready. There was a male just past the entrance that was actively displaying for a peahen…moving both the upright tail feathers and the supporting structures behind the big tail. The birds were also vocalizing the whole time we were at the zoo.

Daffodils were replaced with irises blooming in clumps along the walkways and the sides of the stream.

I enjoyed the enclosure for flamingos, roseate spoonbills, and scarlet ibis.

There was one flamingo that was sitting and kept its head in the dirt…perhaps not feeling so well. All the other birds seemed to be active (particularly the spoonbills) and enjoying the afternoon.

I zoomed in on some feathers that had been shed in the enclosure. It is interesting that the feathers are white toward the base….very colorful in the part furthest from the body of the bird (when attached).

The trumpeter swans were on the pond as they were last time – perhaps a little perturbed by the tree trimming that was happening nearby.

Both the cheetahs and lions were out – and one of the cheetahs was moving around a lot. It could have been responding to the extra noise.

One bongo was relaxing while the other nibbled at leaves.

I zoomed in on the elephant’s eye – realized that they are amber in color. A keeper came to give hay to the elephant and asked if we had questions. I asked if all elephants have amber eyes and evidently that is the eye color for Asian elephants. The elephant is named Patience and she is a geriatric elephant; she likes to be alone rather than with the other female (they don’t get along).

I took another picture of the little elephant sculpture…probably my favorite sculpture at the zoo. I think the shiny top of its head is where people touch it the most!

It was starting to sprinkle but we wanted to see the giraffes. One of the young ones was intent on getting some grass near the fence.

My brother-in-law became mesmerized watching a little girl held by her mother feed the giraffes romaine lettuce; she was an expert…must do it frequently.

We headed back to the zoo store where my sister bought one of almost every item shaped like a turtle! It was a good finale for our visit to the zoo.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Do societies grow more fragile and vulnerable to collapse? - The world is hardly immune to increasing inequality, environmental degradation, and elite competition – all factors which have been proposed as precursors to collapse earlier in human history. Industrialized production, enormous technological abilities, as well as professional bureaucracies and police forces will all likely create more stable, resilient states. However, our technology also brings new threats and sources of vulnerability, such as nuclear weapons and the faster spread of pathogens. We also need to be wary of celebrating or encouraging the entrenchment of authoritarian or malevolent regimes. Resilience and longevity are not de-facto positive.

Solving the riddle of the sphingolipids in coronary artery disease - Boosting levels of a sphingolipid called S1P in artery-lining endothelial cells slows the development and progression of coronary artery disease in an animal model.

“Porcelain Gallbladder” Identified in Mississippi - Identified among a woman's 100-year-old bones exhumed from the cemetery at the site of the Mississippi State Lunatic Asylum. A porcelain gallbladder forms through calcium build-up in the wall of the organ, which causes it to harden.

World's chocolate supply threatened by devastating virus – Oh no! About 50% of the world's chocolate originates from cacao trees in the West Africa countries of Ivory Coast and Ghana. The damaging virus is attacking cacao trees in Ghana, resulting in harvest losses of between 15 and 50%. Farmers can combat the mealybugs the spread the virus by giving vaccines to the trees to inoculate them from the virus. But the vaccines are expensive, especially for low-wage farmers, and vaccinated trees produce a smaller harvest of cacao.

WHO redefines airborne transmission: what does that mean for future pandemics? - Virologists now acknowledge that SARS-CoV-2 spreads mostly by airborne transmission of small particles that are inhaled and that can remain in the air for hours — a method that was previously called ‘aerosol’ transmission. It also spreads by larger ‘droplets’ of virus-containing particles on surfaces, including hands, or ejected over short distances. The WHO document sets an important benchmark for how the world responds to the next pandemic. “The next pandemic will most likely be a respiratory virus again because that’s normally the pathogen that mutates the fastest.” The report’s clarity around transmission will help public health providers to respond appropriately. “They will then consider masking early, they’ll consider ventilation early, they’ll consider all these precautions early because a precedent has been set already.”

Human muscle map reveals how we try to fight effects of aging - As we age, our muscles progressively weaken. This can affect our ability to perform everyday activities like standing up and walking. However, this study also discovered for the first time several compensatory mechanisms from the muscles appearing to make up for the loss.

USDA announces new school meal standards that call for less sugar, salt in students' food - Schools also have the option to require locally grown, raised or caught agricultural products that are unprocessed, while the new standards limit the percentages of non-domestic grown and produced foods that schools can serve to students.

Plastic-choked rivers in Ecuador are being cleared with conveyor belts - Azure system's simple design has the capacity to stop and collect around 80 tons of plastic per day. At this particular point in the San Pedro River, the most it's collected in a day has been 1.5 tons of plastic and synthetic fabrics – that's roughly the same weight as a female hippopotamus. The Azure system is a boom device that stretches across the river to stop objects floating on the surface. It extends down 60cm (2ft) into the water, allowing fish and other organisms to move freely below, and is placed at an angle allowing the natural water flow to direct all debris into one corner of the riverbank.

First glowing animals lit up the oceans half a billion years ago - Some 540 million years ago, an ancient group of corals developed the ability to make its own light. Bioluminescence has evolved independently at least 100 times in animals and other organisms. Some glowing species, such as fireflies, use their light to communicate in the darkness. Other animals, including anglerfish, use it as a lure to attract prey, or to scare away predators. However, it’s not always clear why bioluminescence evolved. Take octocorals. These soft-bodied organisms are found in both shallow water and the deep ocean, and produce an enzyme called luciferase to break down a chemical to make light. But whether glowing octocorals use their light to attract zooplankton as prey or for some other purpose is unclear.

Peatlands Are One of Earth’s Most Underrated Ecosystems - Peatlands are spongy, waterlogged soils composed in part of decaying plant matter. They’re found all around the world, and despite covering only 3% of Earth’s surface, store around 30% of all the carbon on land.

Ten Little Celebrations – April 2024

April 2024 has been even more full of little celebrations than usual; it was challenging to choose the top 10!

Traveling with my daughter. Taking a road trip to Dallas (a familiar trek) is quite different when my daughter to with me. We start the driving a bit later and, this time, we stopped in Joplin on the way home for lunch. I celebrated the time in the car…the great conversation.

The life of a cousin. It was bittersweet to go to the funeral of a cousin that was younger than me…but it was clearly a celebration of her life.

20 puzzles for $2 each. The Friends of the Library book sale in my county included puzzles and I celebrated getting 20 of them for my dad and the other residents at his assisted living group home. I also celebrated a return to volunteering - helping with the book sale.

iPhone 15 Pro Max. Getting a new phone is always cause to celebrate….even though I started out a little anxious that it would a little challenging to go from my old Android phone to an iPhone; it was a pleasant surprise to realize it was pretty easy. The only downside was the reduced functionality of the Windows phone link app for text messages; that issue was resolved as soon as I transitioned to a Mac later in the month.

MacBook Air 15”. More new technology I am celebrating; it only took about 24 hours for me to become a fan of the Mac after using Intel-based machines since the 1980s.

Irises. The plants bloomed all at once. In one bed the stalks were too tall for them to remain standing to I cut them to enjoy indoors – celebrated the buds opening all along the stems.

14 ducklings. Seeing Mom Mallard with her ducklings is a great celebration of spring.

Solar Eclipse. So glad we made the effort to position ourselves to see a 2nd solar eclipse (the 1st for me was in 2017). It’s a phenomenon rare enough to be a celebration.

Belted Kingfisher. Celebrating a bird I didn’t expect to see around our neighborhood pond.

Kite and Pinata Festival. The botanical garden is a great place for outdoor celebrations like this.

Gleanings of the Week Ending April 27, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Meet the World’s Largest Freshwater Crayfish – The Tasmanian giant crayfish. Their numbers are declining due to fishing and disturbance.

FDA urges Congress to pass bill mandating food manufacturers test for lead – I am surprised Congress did not pass this already. According to the U.S. Disease Control and Prevention, there have been at least 519 confirmed, probable and suspect cases of lead and chromium poisoning traced to imported applesauce pouches produced by brands WanaBana, Schnucks and Weis. Lead exposure in children is associated with learning and behavior problems, as well as hearing and speech issues and slowed growth and development.

Retention ponds can deliver a substantial reduction in tire particle pollution - The presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. Tire wear particles significantly outweighed other forms of microplastics, such as plastic fibers and fragments.

Climate change is fueling the US insurance problem – I’ve seen more articles about this recently….there is no good news re insurance…nothing that can overcome what climate change is doing. One state-level action that could help mitigate the impacts of climate change is the implementation of flood disclosures. Organizations like the Natural Resources Defense Council have urged states to require flood disclosure polices during property sales to help buyers decide whether buying is worth the risk. Research has shown disclosure can devalue flood-prone properties and discourage development in risky areas. Even though the number of states requiring flood disclosure policies is slowly increasing, Florida remains noticeably absent, and one-third of states still have no requirement that sellers must disclose a property's flood risk to potential buyers.

Does the time of day you move your body make a difference to your health? – Maybe – for people living with obesity.

How the iron lung paved the way for the modern-day intensive care unit – The iron lung was first used to save the life of a child in 1928. It swiftly became a fixture in polio wards during the polio outbreaks of the subsequent decades, particularly from 1948 until the vaccine was developed in 1955. And its creation paved the way for many subsequent medical innovations. Some patients spent just a short time in the iron lung, perhaps weeks or months until they were able to regain chest strength and breath independently again. But for patients whose chest muscles were permanently paralyzed, the iron lung remained the key to survival.

Food security in developed countries shows resilience to climate change - Data on American wheat production, inventories, crop area, prices and wider market conditions from 1950 to 2018, together with records of annual fluctuations in the weather for the same period reveals strong evidence of an increase in weather and harvest variability from 1974 onwards. However, Wheat prices remain relatively stable, along with the price of associated goods mainly due to farmers and agricultural industries providing a buffer, smoothing out any bumps in the supply of grain to retailers and consumers.

Where the Xerces Blue Butterfly Was Lost, Its Closest Relative Is Now Filling In - Silvery Blues collected 100 miles south of San Francisco were released at a restored a swath of dunes in the Presidio, a former military base, trying to bring back native wildlife. They will pollinate native flowers and form a critical link in the food chain there.

Colorless, odorless gas likely linked to alarming rise in non-smoking lung cancer - 5-20% of newly diagnosed lung cancers occur in people who have never smoked, many of whom are in their 40s or 50s.  Non-smoking lung cancer cases is likely linked to long-term, high exposures of radon gas. This colorless, odorless gas is emitted from the breakdown of radioactive material naturally occurring underground that then seeps through building foundations. The gas can linger and accumulate in people's homes and lungs silently unless they know to test for it. We had our Missouri house tested and radon remediation installed before we moved it!

Contents of Roman Lead Coffin Examined in England - The examination of the contents of a Roman lead coffin discovered in 2022 in the city of Leeds has identified the partial remains of a child (about 10 years old). The initial evaluation of the coffin’s poorly preserved contents found the remains of a woman between the ages of 25 and 35 at the time of her death some 1,600 years ago, a bracelet, a glass bead necklace, and a finger ring or an earring.

Road Trip to Dallas – April 2024

Last week I made a 2-day road trip down to Dallas to visit with my dad. It’s about 7 hours of driving in each direction. When I left my house in Missouri on the first day it was dark. Just as the horizon was beginning to brighten behind me, I saw a large bird fly over the interstate – higher than my car but not that far in front of me. I wondered if it was a barn owl although I didn’t get a good enoug look other than to realize the bird had a lot of white.

After my first rest stop the sun was up and more birds were moving about. I saw a large one fly across the highway…a little lower than was safe and then just above my car there was another of the same kind. It was a turkey! I was close enough to see the eye glinting.

I saw a great blue heron flying along or over the road twice…and a murmuration of smaller birds that spilt in two over the highway.

The highlight of the drive down was the rest stop on US 75 just after crossing from Oklahoma to Texas. The berm between the highway and the rest stop parking was full of wildflowers!

Closer to the building there were beds of wildflowers…including the Texas state flower: bluebonnets.

I enjoyed trying my new iPhone 15 Pro Max phone to take some macro pictures of some of the flowers.

Heading home the next day, I left the hotel about 6 AM and got to Hagerman National Wildlife Refuge about 20 minutes after sunrise. Unfortunately, it was very cloudy and sprinkling so there was not a lot of bird activity, and the light was not great for photography.

The surprise of the morning came when I saw something on the road in my left peripheral vision as I moved slowly along Hagerman’s wildlife road…..as I turned to see it better I realized it was a hub cap. I got out of the car to see if it belonged to my car…and it did! It was the first time anything like that has happened to me in 55 years of driving! I put the hub cap in the car opting to not try to put it back on until I got home.

I saw two flocks of cattle egrets as I was driving back toward the highway from Hagerman.

As I drove through Oklahoma, I was driving thorough moving cloud shadows. They were moving in the same direction as I was, and I was moving faster than they were!

The drive was very routine until my route direction shifted from north to east. The wind buffeted the car and the big trucks on the interstate were even more impacted. The last 3 hours were exhausting – requiring both hands on the steering wheel and hyper awareness of the vehicles (particularly trucks) around me.

I made it home in a reasonable time but was very tired.

Gleanings of the Week Ending April 20, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Tax Burden by State – A comparison done by WalletHub that compared the 50 states on 3 types of taxes - property taxes, individual income taxes, and sales and excise taxes - as a share of total personal income in the state.

See a Restored Ancient Roman Helmet—and Two Shiny New Replicas – 2,000-year-old helmet made of silver-gilded iron.

Solar Savings in the US – Looking at the numbers….

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

Texas Solar Power Growth Changing the Shape of Daily Electricity Supply in ERCOT – Looking at the changes between 2022 and 2023…easy to see graphically.

Functional capacity in old age is like an ecosystem that may collapse when disrupted - In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning.

Ming Dynasty Tomb Found in China's Xinfu District – Part of excavations before nearby highway construction begins.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans - The rate with which we perceive the world is known as our "temporal resolution." Though our visual temporal resolution is quite stable from day to day in general, a post-hoc analysis did suggest that there may be slightly more variation over time within females than within males.

Study Reveals Vast Networks of ‘Ghost Roads’ in Asian Rainforests - An extensive analysis of satellite imagery has uncovered thousands of miles of unmapped roads slicing through Asia’s tropical rainforests - “ghost roads” may be laid down by miners, loggers, poachers, drug traffickers, and land grabbers, often illegally.

Ducklings 2024!

Last year I saw ducklings on our neighborhood pond on April 14th. This year I photographed this year’s brood 3 days earlier than last year on the 11th (although a sighting was posted on the neighborhood Facebook page on the 9th). There are 14 ducklings this year; no losses so far. The Mom Mallard was wisely keeping them close to shore protecting them from the turtles (turtles can pull a duckling underwater, drown it, and then eat it). Click on the images below to enlarge…see if you count 14 ducklings. When they are close to shore, one or two seem to always want to climb up on the mud and nibble the grass. The last picture has all 14 (I think). Their down make their bodies look out-of-focus, so count the heads!

Zoomed in, the ducklings show how fuzzy they still are.

Mom Mallard took them on a brief loop out into the pond before going back to the shore. The line of ducklings is somewhat easier to count.

I noticed some other things around the pond: robins,

Plastic swans (an attempt to deter geese from nesting near the pond),

And, of course, turtles. Most were red-eared sliders; there might be one that I photographed that was something else. I didn’t see the large snapping turtle. I’m not sure how large a turtle has to be to pull down a duckling. Fortunately, the Mom Mallard was keeping them at the other end of the large pond.

Before I headed home, I saw the ducklings again in the inflow channel of the large pond; there had been enough rain recently that there was still water in it and the ducklings were loving it! They were moving around finding bits of food and sitting down letting the water move around them. I wondered where the Mom Mallard had made her nest since they seemed to be heading up stream.

Then and Now: Groceries

In the 1960s, my mother did the grocery shopping for the family – usually going once a week.  I went with her occasionally but not often. She usually shopped while my sisters and I were in school. Her favorite grocery store was Safeway. I am now shopping at Walmart most of the time since it is the closest grocery store to me and once a week is still my goal. The hours my The Walmart is open from 6AM-11PM, 7 days a week; the hours grocery stores were open in the 1960s was a lot less than that and there were items they couldn’t sell on Sundays if they were open then (‘blue laws’ in Texas).

The carts were similar in design to the larger ones in most stores now although they were all metal (no plastic) and did not have seatbelts for young children. Most grocery stores now  have a few smaller carts along with the larger ones but I usually am buying enough that I get a large cart.

My mother always had a list that accumulated over the week; most of the time she made the additions to the list but as my sisters and I got old enough, we sometimes wrote in items. Now I use the OurGroceries app so that my husband and I can add items to the list from any of our devices and I use my phone when I am in the store rather than a piece of paper.

My mother only bought food at the grocery store…not toiletries or over-the-counter medications; those were purchased at a drug store which also included a pharmacy. I buy many non-groceries during my weekly shopping now; toiletries are frequently on the list, but I sometimes buy clothes or office supplies as well. It’s an advantage of shopping at Walmart rather than a grocery store. We still pick up our prescriptions at a CVS; the pharmacy at Walmart is not open at the time I usually shop (between 7 and 8:30 AM on Friday mornings).

At checkout, a cashier had to enter the price of each item on the register and the strip of paper that my mother was handed at the end only included the prices and the total. She paid with cash or wrote a check. Now I scan my purchases myself, use a credit card to pay for them, and get an itemized list that includes an abbreviated description of each item along with the total.

Mother’s purchases were put in brown paper bags by the cashier. Now the store provides single-use plastic bags; I’ve used my own bags for more than a decade (they are stronger, and I don’t have to take precautions to contain the single-use bags from littering and polluting the environment). I put my items into my bags after I scan them. All the refrigerator items go into an insulated bag and the remaining items are grouped into bags to make unloading easier once I get home (and to make sure bread, chips, and eggs are not damaged in transit).

There was a lot less plastic. Milk came only in cartons (waxed…not plastic coated) and juices and soft drinks came in glass. Canned foods were purchased frequently, and the cans were not lined with plastic. The produce section included mainly seasonal foods along with ones that could be easily stored/transported (like bananas). Broccoli was something we had periodically as a frozen vegetable, and it was packaged in a box rather than a plastic bag.  We enjoyed strawberries seasonally or frozen (in a box); now my husband likes the frozen ones (in a plastic bag) more than he likes fresh ones! Plastic is the dominate packaging now: jugs of milk, bottles of water/soft drinks/juice, bags of frozen veggies and fruit, robustly sealed meats, bags of snacks and fresh vegetables/fruits, jars of peanut butter. Sometimes there is an option to buy in class jars but most of the time there is no choice; the packaging is plastic.

The most common type of bread was white; my mother wanted ‘whole wheat’ and bought Roman Meal when she could find it. I buy Dave’s Sprouted organic bread….avoiding a lot of added chemicals that have been introduced over the years to keep bread from molding or otherwise ‘improving’ it in some way (‘improving’ is in quotes because many breads cross over into the ultra-processed realm with the additions that are quite common today).

Some of the brands are still around: Cambell’s, Nabisco, Kelloggs, Green Giant. I don’t buy them as often as my mother did…only Cambell’s Tomato Soup and Green Giant Niblets Corn for my husband.

There are a lot of products in the grocery store that were not available in the 1960s…most of them ultra-processed and they fill up whole aisles of the grocery store. It requires some willpower to steer clear of those (although it gets easier over time). On the healthier side, it is now easier to find international foods (salsas and tortillas, etc.) and things like boneless chicken breasts…a lot more options when it comes to pasta, sauces in glass jars, greens (kale and arugula were not in grocery stores in the 1960s), grains/seed (quinoa and chia are new…’chia pets’ were not introduced until the later 1970s), and no salt seasonings. There are now targeted foods for special diets; for example, milk that includes Lactaid for those that are lactose intolerant and protein shakes for diabetics or those dieting and concerned about getting adequate protein.

My mother was very conscious of nutritional guidelines; she had taken home economics courses in college. We had some form of protein at every meal along with fruits and vegetables and grains. Sugary items were only for special occasions. There were seasonal fresh foods, but she relied on canned goods more than we do now, particularly during the winter. Both sets of grandparents had big gardens and we enjoyed their bounty whenever we could – supplementing what was purchased at the grocery store; we knew how food was grown and a little of how it was preserved (canned) for later. Now we buy more fresh or frozen fruits and veggies rather than canned because they are readily available during the whole year. I also buy organic as much as I can….something that didn’t exist in the 1960s.

Groceries have changed significantly since the 1960s. Availability of healthy foods is probably better now – although it takes more attention/knowledge to avoid the ultra-processed foods that are often intermingled with the healthy food.

Gleanings of the Week Ending April 13, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

Solar Eclipse – Part 1

We traveled from our home near Springfield MO to Poplar Bluff MO for the solar eclipse on April 8th. There was a flurry of activity on the day before the event to finalize our destination; the weather forecast was the key driver for us to choose Poplar Bluff (along with Whitely Park being a good location that was not included as part of the event planning by the city).

We left our house at 5:30 AM to pick up our daughter and son-in-law before heading east; it wasn’t long before sunrise. I took some pictures of it through the windshield of the car (my husband did all the driving).

We did not encounter any heavy traffic during our morning drive…got to the park 2 hours before the first contact…plenty of time for set up and looking around the park. We set up on an asphalt parking lot that never completely filled up so we spilled over onto the two spaces on either side of where we were parked next to a fenced soccer field.

I walked around to look at a few low growing plants…

And trees that were just beginning to leaf out. I realized that the trees did no have enough foliage to make projected crescent patterns onto the ground as happened when we were in Loup City, Nebraska for the August 2017 solar eclipse.

On the ground – I noted roots of a sycamore, seed pods of sweet gums (from last year and green ones from this year) and a clump of green (probably a weed) surrounded by brown thatch.

There were birds about:

Two purple martin houses that were beginning to be populated. One had a pair of house sparrows too; I wondered how long it would take for the purple martins to evict them.

A starling in the grass – keeping an eye on the sky.

And a group of robins in a tree without leaves but lots of twigs that made it hard to get a good image.

I took most of my eclipse pictures with my bridge camera (Canon Powershot SX70 HX) on a tripod with a solar filter taped to the camera body to cover the lens until totality). I had eclipse glasses that I wore to look at the sun with my eyes and put over the camera on my iPhone to take one picture. I’ll post my eclipse pictures on Sunday along with some my husband took…stay tuned for that.

Gleanings of the Week Ending April 6, 2024

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

What do terracotta warriors tell us about life in ancient China? – Discovered 50 years ago…they are a snapshot of the soldiers of Qin – the feudal state that unified China, for the first time in 221BC under the country's first emperor Qin Shi Huang – from the soles of their shoes to their candy-colored clothes to the bronze weapons buried with them to their distinct facial features. 2,000 terracotta warriors have been excavated but more are uncovered every year.

This Map Shows Where Planting Trees Would Make Climate Change Worse - Trees draw down carbon dioxide from the atmosphere, helping to keep warming in check. But their dark, green leaves also absorb heat from sunlight. Snow and sand, by virtue of their light color, reflect more sunlight back into space. As such, trees planted in snowy areas or in the desert will absorb more sunlight than their surroundings, which may negate the climate benefits of soaking up carbon dioxide.

These 3,000-Year-Old Treasures Were Forged from Meteoritic Iron - In the 1960s, researchers discovered a trove of Bronze Age treasure in Villena, Spain. New research has revealed that some of them made between 1400 and 1200 B.C.E. were forged from iron from a meteor that struck Earth a million years ago. Who manufactured them and where this material was obtained are still questions that remain to be answered.

Vernal Pools Make Your Garden Sing - It’s not just frogs that are making homes in these little pools of water. Less vocal species like salamanders, dragonflies, fairy shrimp, and even dozens of native plants are there too. Even more species than that can be found simply visiting the pool for a drink or snack, including great blue herons, wood ducks, and box turtles.

Return of Trees to Eastern U.S. Kept Region Cool as Planet Warmed - Over the 20th century, the U.S. warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). A new study posits that the restoration of lost forest countered warming, keeping the region cool. Still, the return of trees can only partially account for the drop in temperature. Other possible explanations include the growth of irrigation, a source of water vapor, and the uptick in particulate pollution, which reflects sunlight, thereby cooling the air.

Sweetened drinks linked to atrial fibrillation risk - 20% higher risk of irregular heart rhythm, known as atrial fibrillation, among people who said they drank two liters or more per week (about 67 ounces) of artificially sweetened drinks. The risk was 10% higher among people who said they drank similar amounts of sugar-sweetened beverages.

Measles outbreaks and what parents need to know - Measles can lead to complications such as ear infections, diarrhea, pneumonia, and encephalitis (brain swelling). One to three of every 1,000 children infected with measles dies. More than 97 percent of the people who have had their two shots of the vaccine never get measles.

A new world of 2D material is opening up - 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it's about scaling up the synthesis and doing it in a sustainable way.

In Cleveland, mushrooms digest entire houses: How fungi can be used to clean up pollution - Fungi can eat the noxious waste from abandoned homes. Heavy metals and other toxins are extracted and captured in the mushrooms that grow, while the substrate leftovers, including the mycelium, are compacted and heated to create clean bricks for new construction. The resulting "mycoblocks" have a consistency akin to hardwood and, depending on the specifics of the manufacturing process, have been shown to be significantly stronger than concrete.

Arctic nightlife: Seabird colony bursts with sound at night - Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.

When does a road trip become a commute?

The road trips to Carrollton/Dallas TX have been going on for years – increasing in frequency in recent years as my parents got older. Until recently their duration as been for at least a week; from Maryland it was a 2-day road trip in each direction which was reduced to 7 hours once we moved to Missouri. Sometimes I stayed longer – for hospitalizations/recuperation primarily. There were no trips at the beginning of COVID, but they started up again as soon as we were vaccinated. They are almost always on my own and my parents’ house became almost like a second home since I was spending at least 25% of my time there.

Since my mother’s death and the sale of their house, things are changing. I drive down one day and come back on the next – visiting with my dad for a few hours and staying in a hotel overnight. I’ve done it 3 times and am beginning to realize that the road trip feels more like a long commute.

The route is becoming very familiar. I set the navigation system but really don’t need it. The places I stop (usually Loves or Pilot….sometimes Choctaw Travel Centers) are familiar. There was a Stuckeys that I stopped at occasionally, but it was always a bit grungy and I noticed on the last trek that I had closed. My route is not on Interstate for the most part and I am very aware of the speed limits going though towns.

Music helps keep me alert…and variety helps. Apple Music on my phone playing via Bluetooth on the car speakers is the way to go!

There are several assignments I give myself to stay focused on the road and surroundings. Some of my favorites are:

  • Observing birds (particularly hawks in treetops, great blue herons or great egrets flying, soaring vultures, murmurations of smaller birds….hoping to see a bald eagle). It’s depressing to notice hawk or owl roadkill, but it happens.

  • Noticing the trees – particularly in the spring and fall. Recently I have been paying particular attention to red buds which are scattered among the roadside trees….not thrilled about the escaped Bradford Pears (Callery Pears) that are also there.

  • License plates, particularly in Oklahoma, are more varied than in most states because the Oklahoma tribes have their own plates! Most of my observing of plates is during the times I’ve slowed down for a town and there is more traffic.

  • There is plenty of time to plan what I need to do when I get to Dallas…or when I get home. On the way down, I think about topics that might interest my dad and whatever estate actions I need to take. On the way home, I think about blog posts and, this time of year, what I need to do in the yard.

Phone calls generally factor into the time I am in the car – hands free of course. I call my husband to let him know when I will get home, and my daughter usually calls me for a longer chat when she knows I am driving. It helps pass the time.

More focused purpose. I am realizing that the trips have one overwhelming purpose – to see and visit with my dad. It’s a few hours rather than 24/7 for a week like it was before. There is not much time for anything else although brief times out in nature might still happen…although not on every trip.

And that is how my road trips to Texas have become more like a commute.

Dickerson Park Zoo (2)

Continuing about our visit to Dickerson Park Zoo

The animal sculptures in various places around the zoo are interesting as sculptures…and sized to provide good climbing experiences for young children.

I realized about halfway through our visit…that I was somehow skewing toward photographing birds more than other animals. The grey-crowned cranes are one of my favorites in zoos I visit.

There were children feeding the giraffes….and I tried to get a picture of the youngest one. It is still the smallest…but growing fast; the adults don’t give the youngest a break at the feeding platform, but the human children try to hold out to feed the ‘baby.’

There were two white storks. I wondered if they had an egg.

The red ruffed lemur responded to a sound my son-in-law made…I took a picture through the glass of its enclosure.

The king vulture enclosure contained two birds…they have very unusual heads (the glass between my camera and the birds was not very clean unfortunately).

Several capybaras were relaxing in the afternoon sun. Just before I wrote this, I found out that my grandnephew had gotten a plush toy capybara at the San Diego Zoo on the same day as our visit to the Dickerson Park Zoo; what a coincidence!

Dickerson Park Zoo (1)

We enjoyed the Dickerson Park Zoo (Springfield MO) on a cool sunny day in late March. My husband and I got a gift membership from my daughter, so we’ll go several times this year. The zoo is always a great opportunity for photography.

The peacocks that roam freely are always photogenic. The birds are very acclimated to people although all the visitors gave them plenty of room too. I only saw one in full display – tail up and expanded; there was no females around, so it wasn’t clear what prompted the display.  The males seemed to be the only ones out during this visit; I wondered if the peahens were sitting on eggs.

The flamingo enclosure is one of my favorites because there is an area where there isn’t a barrier (mesh or fence) between my camera and the birds. I zoomed in on one I thought was sleeping; I liked the arrangement and color variation of the feathers; I discovered when I got home that the bird was evidently awake!

The Trumpeter Swans were living up to their names as the made their way around the pond…very noisy. Beads of water on the swan’s back show how well the feathers keep the swan from feeling wet!

The zoo still has a lot of daffodil/narcissus flowers. Our shifts between warm and cold days (and back again) seems to be prolonging the blooms this year. They are planted around naturalized rivulets.

More pictures from the zoo tomorrow….
