Gleanings of the Week Ending December 11, 2021

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.

Top 25 birds of the week: Shorebirds! – Always lots to see looking at birds!

Everglades' Wading Birds Had Mixed Success In 2020 – Overall wading bird nesting in South Florida has increased…but is still a fraction of the target. In 2020, an early arriving rainy season impacted the availably of food for chicks.

De-cluttering may not help people with dementia – People with moderate dementia perform better surrounded by their ‘usual’ clutter!

U.S. Is World’s Top Generator of Plastic Waste – Not surprising. And the US should take the lead in figuring out what to do about it: how to produce less and recycle more.

A Mosaic From Caligula’s ‘Pleasure Boat’ Spent 45 Years as a Coffee Table in NYC – Still a lot of mystery about how the mosaic got from its recovery when Lake Nemi was drained by Mussolini and then becoming the top of a coffee table for 45 years. It was seized in 2017 and returned to the Italian government.

Roadrunner: Meet the Real Bird Behind the Cartoon – I can remember seeing one a little north of where my parents live now (north of Dallas) in the 1980s…but they are probably long gone from that area now. I’ve seen them in west Texas more recently; one was at a rest stop between San Antonio and Laredo. They always seem to thrive in relatively harsh environments.

The bustling hidden world of hedgerows – The closest we come in North America to hedgerows are fencerows or windbreaks….and even those have been reduced over the years. Near where I live the advent of glyphosate/Roundup ready crops has eliminated the herbaceous growth along the edges of fields which in the past included milkweed and other plants that were attractive to butterflies and other small animals.

Master Artisans Fixed Mistakes Made by Apprentices at Ancient Egyptian Temple – I enjoyed the 6 minute video in this post…it’s quiet enough to hear the birds in the ruins.

Managing water resources in a low-to-no-snow future – We need to be thinking of adaptations to this manifestation of climate change now rather than waiting since the solutions will be challenging….take time to design and construct.

Old-fashioned rice custard – I have a container of rice from some Chinese takeout…..and plan to make this rice custard. I am anticipating that it will be yummy (and high protein too).

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.

How driverless cars will change our world – A little realism in the projections….rather than hype. Hopefully by the time I am old enough to no longer want to drive myself, driverless car options will be convenient and safe.

Ubiquitous food additive alters human microbiota and intestinal environment – The research was about carboxy methyl cellulose specifically. As I read the article, I wondered if this additive -that isn’t really about the nutritional value of the food at all – is one of the ways ultraprocessed foods are bad for us in unintended ways.

120 Volt Heat Pump Water Heaters Hit the Market and Make Gas Replacements Even Easier – This is good news. I’ll be watching as these come on the market…see how they are reviewed. I am assuming a line will quickly form with people wanting to replace their gas hot water heaters!

When Wildfire comes to Nature Conservancy Preserves – The preserves are managed with prescribed burns and forest thinning…and can provide examples of effective ways of managing wild areas against destruction by wildfire.

Children’s Teeth Reveal Breastfeeding Practices in Ancient Peru – A detailed study of the remains of 48 children from 2,500 years ago revealed that they were breastfed exclusively for the first 6 months of life and were weaned when they were about 2.6 years old. I wonder how many other ancient cultures have been studied this way.

Transparent Solar Windows: You Ain’t Seen Nothing Yet – If solar windows could be produced at reasonable cost….a lot of people would be motivated to replace their windows/power their house. There is a pleasing aesthetic to this type of solar power too.

Why Putting Solar Canopies on Parking Lots is a Smart Green Move – A great idea…hopefully it becomes the norm. The first one I noticed was at the Patuxent Research Refuge.

Top 25 birds of the week: Nectar Feeding Birds – Always worth looking at some bird pictures!

The Colon Cancer Conundrum – Research is trying to determine why rates of colorectal cancer are climbing in younger adults….staying level for other age groups.

Our National Monuments, a Photographic Testimonial to Wild America – Some more places I want to visit (via an extended road trip perhaps).

Top 25 birds of the week: Predatory Birds – Starting out the gleanings list this week with birds…and photography.

The ingenious living bridges of India – Maybe other kinds of structures could be grown instead of built. The bridges look like Ewok structures from Star Wars movies!

Watch Over 150 Bison Weave Through Traffic in Yellowstone as Winter Migration Begins – I remember bison on the roadway during the early summer we went to South Dakota more than 20 years ago. It is an awesome experience to see them – using the car as a blind.

Chocolate: From Witchcraft to Miracle Worker in Early Modern Europe – A little history of chocolate as it was introduced to Spain.

More than ceremonial, ancient Chaco Canyon was home, new study says – I’ve only visited Chaco Canyon once…want to go again.

Richly Adorned Egyptian Tomb Could Rewrite the History of Mummification – Maybe….there is still testing to be done before the mummy in the tomb is confirmed to be old enough to be the man the tomb was built to hold.

Surprising Tales of Toxic Animals – I enjoyed the historical perspective in the information about several of the animals.

A diet of essential amino acids could keep dementia at bay – I wonder how long it will be before the patent for the supplement is awarded…..and it is released as a supplement. Hopefully there will be testing him humans beforehand.

This New Installation Pulled 20,000 Pounds of Plastic From the Great Pacific Garbage Patch – We need to stop producing messes….and clean up the ones we’ve already created. This is one attempt to start a massive cleanup of plastics that are in our oceans.

Bone-loss discovery points to new treatment for osteoporosis – I am glad there is ongoing research on this issue since the existing treatments don’t seem to work that well….often have side effects. Hopefully there will be more effective treatments by the time I might need them.

Thanksgiving

So much to be thankful for this Thanksgiving Day:

My family staying healthy through the pandemic

My daughter coming for Thanksgiving – the first time she has seen her Dad since before the pandemic

So much good food for the day – some traditional and some new this year (strawberry rhubarb pie and orange corn meal muffins)

Weather good enough for a walk after the big meal

A decoration for the front door that can be composted after the 2021 holidays

Happy Thanksgiving!

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.

Lots of wonderful photography posts to enjoy this week: Winners of the Weather Photographer of the Year Contest Celebrate the Beauty of Nature, West Coast Landscape Photographer Perfectly Captures the Region’s Magical Vistas, Awe-Inspiring Winners of the 2021 Natural Landscape Photography Awards, and Photographer Zooms in on the “Hidden Beauty” of Small Seeds and Fruits – Not sure why there seemed to be so many of these in my feeds this week….

What is Play-Doh made of? – Thinking of toys this time of year….play-doh is something that has been around a long time. We don’t have any young children in our immediate family and I’m missing the joy of watching a child at play.

How your house will go carbon free – Efficiency and renewable energy. At least some of the technologies already exist and many can be retrofitted into existing houses.

Armadillos advance northward as temperature rises – I remember seeing armadillos years ago in Texas when we were camping….maybe we’ll be seeing them closer to Missouri and Maryland in the near future – although hopefully not digging up my yard.

Catching up on Top 25 birds of the week: Breeding and November 2021 – I am ready to do some birding…my husband registered us for a birding hike in a Baltimore hike in December and I hope the pandemic will wane enough that the birding festivals will be back in 2022.

Red, White and Green: Winter Colors in Arches are Awaiting You – My husband and I visited some of the Utah parks in October several years ago…and there was already a dusting of snow on some of the mornings and in the mountains. Maybe we’ll go in November next time.

California Condors Surprise Scientists With Two ‘Virgin Births’ – Maybe this happens in other species too. There was no way to verify the phenomenon before genetic testing became available.  

Seeing Red: What the Color of House Finches Can Tell Us – House Finches are frequent visitors to our bird feeders. It was good to learn more about them from this blog post.

For women, greater exposure to estrogen in life may protect brain regions that are vulnerable to Alzheimer’s – This post left me wondering if estrogen mimics in our environment (i.e. pollution) might be protective as well…and, if so, will younger women be less likely to experience brain shrinkage after menopause than the older generations of women are experiencing.  

Why mandatory vaccination is nothing new – A little history of vaccine mandates. I didn’t know that George Washington required all troops to be inoculated against smallpox in 1777!

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.

The great experiment to put a price on nature – Whether it’s toting up ecosystem services or simply realizing that Mother Earth is our one and only…we should all realize that we need to start taking care of ‘nature’ a lot better than we have in the past.

Microplastics May Be Impacting the Climate, Study Finds – A starting point for combining climate science and microplastic science into a model….still a lot if refinement/additions. We already know that the microplastics in our atmosphere are increasing so whatever impact they have it will likely be increasing during the time the model is being refined.

Ancient Stone Ram Heads Unearthed on Egypt’s ‘Avenue of the Sphinxes’ – New finds…and part of an advertisement for some restored places reopening in early November. Are tourists ready to travel again to places like Egypt?

Spending time in nature promotes early childhood development – A study from metro Vancouver of 27,372 children from birth to age 5… that pushes us to get serious about making sure spaces for children include a lot green space…that includes day care and preschools and K within the age range for this study. And while we are doing that – let’s think about how important green space is to everyone else too.

Meet the muskrat: push-up champion of cattail marshes – This article made me wonder if muskrats eat phragmites – and a plant that is taking over marshes. I found an article that says they do…at least in some situations.

Changing ocean currents are driving extreme winter weather – Looking at the impact of the slowing Atlantic Meridional Overturning Circulation (AMOC) and extreme cold weather (like in Texas last February) using a high-resolution global climate model. They’ve only done the simplest model (turning off the AMOC) so far…but plan to refine it to address the more complex reality.

Finding Fall Colors At Bandelier National Monument – I hope everyone found someplace to enjoy fall colors these past few weeks. My main opportunities were in my own backyard and as I was driving down the highway between Maryland and Texas!

Cheers! Wine’s red grape pulp offers nutritional bounty – Not compost or fodder...getting more than wine from vineyards!

Hit the sleep ‘sweet spot’ to keep brain sharp – Evidently 5.5-7.5 hours of self-reported sleep is about right.

2021 EPSON International Pano Awards Celebrate the Creativity of Panoramic Photography – Enjoy some eye candy as the last of this week’s gleanings!

Gleanings of the Week Ending November 6, 2021

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.

Why do we hate trash birds? – A little about the way we dismiss birds we see frequently (maybe too frequently) and the difference in the birds viewed that way in the US and Australia. The Australian white ibis is nicknamed ‘bin chicken’! Here in the US, some people think of pigeons and Canada geese and mallards as ‘trash birds.’

Flu and heart disease: The surprising connection that should convince you to schedule your shot – Flu vaccines save lives…particularly lives of people with heart disease. An improvement the article suggests: make sure cardiologists stress the need to get the flu vaccine to their patients – not just assuming the primary care doctor will do it.

AAA: Vehicle auto safety systems often fail when driving in heavy rain – I’ve observed this several times but is the first time I’ve seen the recommendation to ‘avoid using cruise control in wet and slippery conditions.’ The cars should probably provide warning messages more overtly to not rely on certain driver aids in bad weather.

By 2500 Earth could be alien to humans – The projections of models used now are out to 2100…that is not far enough into the future. We can’t assume that we’ll succeed in reversing climate change by that time…or maybe we are collectively so pessimistic right now that we think the world will end by 2100.

How to make sustainable choices for a long life and a healthy planet – A summary of some recent studies on health/diet choices and the relationship to climate change. It turns out that it’s pretty easy to eliminate some of the most unhealthy items like soft drinks and foods with lots of sugar. It’s a learning experience to shift to meals to plant based protein…for me – it’s still a work in progress.

The plastic recycling system is broken – here’s how to fix it – I agree that it is broken…but I’m not sure that what is suggested in the article would be enough. We need packaging solutions that are not plastic at all! I have tried to eliminate as much single use plastic as I can since even with perfect recycling, I’m not sure I want things like food to be in plastic packaging (how can we know that the plastic is safe for food). There are so many items that you can’t buy without plastic packaging. The consumer is forced to be part of the problem even if they want to be part of the solution.

How a simple tummy-rub can change babies' lives – Maybe baby massage techniques should be incorporated in all baby care courses, videos, and books!

7 underrated creepy creatures – A little hold-over on the Halloween theme.

From Homes to Cars, It’s Now Time to Electrify Everything – My existing house has a gas hot water heater and furnace; the other appliances are already electric and I drive a plug-in hybrid which means that most of my around town driving is in an EV. But I don’t have solar panels. My plan is to move in the next year or so and quickly arrange for solar panel installation and transition the house to be all-electric. Next step would be the addition of battery storage. I’m also intrigued by the idea of a wind wall (see next item on the gleanings list).

This ingenious wall would harness enough wind power to cover your electric bill – This could be something that would work for more homes and businesses than solar...particularly if they were relatively inexpensive to produce. There is an aesthetic appeal too.

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.

Environmentally friendly ways to cool homes – This will be an increasingly ‘hot’ topic for individuals and various levels of business and government. Many electrical utilities are already seeing increased energy consumption during the summer.

What’s Up with White Squirrels and Black Squirrels? – I haven’t seen any white squirrels but we have the occasional black one in our neighborhood (in Maryland).

Medical errors keep killing patients – but there are laws, incentives and mindset changes that could reduce the death toll – Medical mistakes are s leading cause of death, behind heard disease and cancer. This should not be the case. Surely incentives can be used to force changes to the unacceptable status quo.

Deaths linked to ‘hormone disruptor’ chemical costs billions of lost US productivity – A study that included more than 5,000 adults ages 55-64 done by NYU Grossman School of Medicine. The people with the highest concentrations of phthalates in their urine were more likely to die of heart disease than those with lesser exposure. I am no longer storing food in plastic containers unless they phthalate free…the bigger problem is cosmetics/hygiene products. It’s hard to know which ones have it.

Why are you seeing lots of vultures now? – Our area has resident turkey and black vultures…we see a few all year long. In the fall we might see an uptick because of vultures from further north migrating through.

Mushroom consumption may lower risk of depression – Yet another reason to enjoy mushrooms in your diet!

US Moving Towards 30% Electricity from Wind & Solar – By 2026! That is not that far away. I know I’ll probably have solar panels on the roof of my house well before that (and probably some energy storage as well).

Possible Mammoth Butchery Site Found in Arctic Circle – On an island off the northern coast of East Siberia. At the time the animal was killed (26,000 years ago), sea levels were lower, and the island was connected to the mainland.

Nature-based activities can improve mood and reduce anxiety – A metastudy that looked at 50 studies and 14,321 NBI records done by the University of York. Interestingly – they didn’t find that the activities improved physical health!

It’s Time to Ban Gas-Powered Landscaping Equipment – We already have some electric landscaping equipment: blower, trimmer, weed eater. The mower will be next. I am looking forward to it since I notice the exhaust smell and get a scratchy throat every time I mow.

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.

Roman noblewoman’s tomb reveals secrets of ancient concrete resilience – This research has application to the future: transitioning to Roman-like concrete could reduce the energy emissions of concrete production and installation by 85%...and improve the longevity of concrete by orders of magnitude.

How to bring more clean energy into our homes – It’s hard to know what to do that will make the most difference in decarbonization. Electrification is good…as long as the energy used to create the electricity is renewable. This article is explaining one attempt to make it simpler…but it doesn’t seem like it goes far enough.

Does the world need more sharks? – Evidently when sharks decline, herbivores increase and seagrass declines….resulting in less carbon sequestration in sea vegetation. So – more sharks would improve our climate change situation!

The incredible opportunity of community schoolyards – Transforming paved public schoolyard by adding trees, gardens and stormwater management systems and opening them to the public after hours….what’s not to like? It is good for children and the community…and reduces the heat island around the school.

Recycled concrete and CO2 from the air are made into a new building material – Potentially another way to reduce the energy and emissions to produce concrete…but there is still a challenge to make it strong enough for all the current places we use concrete - to make calcium carbonate concrete viable in the future.

10 Writing Awards for Cool Green Science – Some of the 10 have probably be in my gleanings before…but they are worth looking at again.

We need to talk about your gas stove, your health and climate change – 35 years ago, I thought gas stoves were wonderful….but I haven’t had one since 1986, and I won’t buy a house in the future with one (or I will replace it immediately). My current house does have a gas hot water heater and furnace…but I plan to jettison those too. And I don’t want a gas fireplace either!

Clean air matters for a healthy brain – I check the Air Quality Index on Weather.com and there are too many days that the PMI2.5 level is ‘yellow’ where I live now in Maryland. I try to not spend a lot of time outdoors on those days.  It’s another something to think about when/if I move out of the area.

The American Bumblebee Has Vanished From Eight States – The 8 states are: Maine, Rhode Island, New Hampshire, Vermont, Idaho, North Dakota, Wyoming, and Oregon. That doesn’t mean other places are much better. They have declined 99% in New York; 50% in the Midwest and Southeast.

Large scale solar parks cool surrounding land – The observation is interesting. I wonder if the solar parks that I’ve seen frequently around airports in the US are large enough to make up for the heat island effect of all the concrete and asphalt surfaces of the airports.

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.

How to Easily Catch Spotted Lanternflies Using a Water Bottle – These insects have invaded Maryland, but I haven’t seen them yet. Maybe this is a reason to put an empty plastic water bottle in the car – just in case.

Exposure to deadly urban heat worldwide has tripled in recent decades, says study – On of the topics in the schoolyard field trip for 6th graders was heat islands – it’s a good example of the impact of climate change around the world.

Smoky Clouds That Form Over Wildfires Produce Less Rain – Drought…forests burning…and then less rain. Aargh!

8 Fall Nature Experiences to Enjoy – There are so many things to enjoy in the outdoors during the fall – as the heat of summer fades away.

Exploring The Parks: 10 Historic Sites To Visit This Fall – More ideas for fall activities. I’ve been to all the sites they list that are on the east coast…but not necessarily in the fall.

NASA and USGS Launch Landsat 9 – The first Landsat was launched in July 1972 – the year my husband and I graduated from high school.

A new solid-state battery surprises the researchers who created it – Solid state electrolyte and an all-silicon anode – faster charge rates at room to low temperatures. There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!

Yale Climate Change Maps 2020 – Results from a spring 2020 poll about climate change.

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.

Earth is dimming due to climate change – Decades of measurements of earthshine indicate that the Earth is becoming less reflective with warmer oceans (and fewer bright clouds).

Kilauea Resumes Eruptions At Hawai'i Volcanoes National Park – Exciting times on the big island…

In UK, Interest in EVs Spikes Amid Fuel Shortages – There have been stories about Ford and GM strategy recently too….lots of indicators that many people will be buying EVs sooner rather than later if enough are produced.

NASA lander records the largest ‘Marsquakes’ ever detected – The lander has been on the surface since 2018!

Dental care: The best, worst and unproven tools to care for your teeth – Hmm….I wonder how much this research will change what dentists advise?

Baby Poo Has Ten Times More Microplastics Than Adult Feces – A scary result…and no ideas on how to reduce exposure (and we don’t know exactly what harms it might cause)….just more research needed. Very frustrating.

Coastal Northeastern US is a global warming hotspot; 2 degrees Celsius of summer warming has already occurred – From Maine to Delaware…the area is warming faster because of climate change linked alterations in the ocean and atmospheric conditions of the North Atlantic.

2021 Nature Conservancy Photo Contest Winners Highlight Global Wildlife and Nature – Beautiful…and thought provoking. My favorite was the artsy one at the end…a high key image.

Paradigm shift in treatment of type 2 diabetes to focus on weight loss – There are probably other chronic ‘diseases’ that have become more prevalent over the past few decades that could be improved with weight loss….but it is hard to lose weight…and keep it off. It requires permanent lifestyle changes.

A Leisurely Trip to Kansas – Another post that includes pictures of a rough green snake. I’ve been on the lookout for them since my son-in-law sent a photo he took with his phone!

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.

The oil-field ‘fugitive’ that can slip into the water supply – The methane leaks into ground water are yet another reason fossil fuel is problematic. The industry evidently can’t or won’t clean up…making moving away from fossil fuels as quickly as possible even more urgent – although climate change should be enough for the world to be doing that already.

Top 25 birds of the week: Brown Birds – Not all birds are colorful! Watching small brown birds can be just as much fun though.

Ancient Human Presence Revealed At White Sands National Park - Researchers Push Back Date Of Human Arrival In North America Thousands Of Years – Fossilized footprints in the gypsum sand playa deposits…dated to the Late Pleistocene.

Mexico’s Ancient Inhabitants Moved Land and Bent Rivers to Build Teotihuacán – Still more being learned from an archaeological site that has been studied for many decades. LiDAR is one of new technologies that is yields a lot of new information.

Poorly circulated room air raises potential exposure to contaminants by up to six times – COVID has prompted more detailed research on this topic…and the discoveries should be used to improve building ventilation systems to help control other air-borne diseases.

Why colorful food is good for you – I like the colors and flavors….it’s an added benefit that they are also healthy choices!

NASA’s James Webb Space Telescope Will Launch Into Orbit in December – Finally!

River research reveals scale of macroplastic pollution – A plastic bottle takes a long time to break down….450 years and requires UV light. With so many bottles getting into rivers around the world, it is important to understand how they travel…how they begin to breakdown. They are going to be around for a very long time and, right now, more are still entering the rivers.

Research shows more people living in floodplains – From NASA. Tragedies that are getting worse as population increases and climate change causes flood risk changes.

Making Beetles Pee Can Protect Your Garden – Maybe this is also a pathway to an effective way to control insects like aphids without pesticides!

Top 25 birds of the week: September 2021 – Such a variety of birds in the world!

The Love Stories of Sleepy Lizards – An Australian lizard…they are monogamous and have a surprising threat display. They have been studied for over 40 years.

Searching for the Fisher Kings – The Calusa of south Florida…a capital on a man-made island made of shell. Surviving the Spanish but not the British.

New Coal Plants Dwindle Amid Wave of Cancelled Projects – Good! We need to be ramping up generation of electricity with renewables….and dramatically reducing the methane released by the oil and gas industry in their extraction processes…and then begin to reduce our need for oil and gas in areas that can be electrified (like transportation and heating/cooling).

Explore Life Under the Microscope with the Winners of the Nikon Small World Photomicrography Contest – Photomicrography frequently creates art from reality that it too small for our eyes to see without the magnification and specialized equipment.

August 2021 global climate summary – From NOAA. Two global maps (temperature and precipitation). Where I live, August was hotter and slightly wetter than the average (averages from 1981-2010 for temperature…from 1979-2020 for precipitation).

People synchronize heart rates while listening to stories – Thinking about the brain as part of physical body….looking at the brain-body connection more broadly.

Study Links Transportation Noise to High Rates of Dementia and Alzheimer's – From Denmark.

Indigenous Resilience Center Launched at the University of Arizona – My daughter did her graduate work at University of Arizona; I’m glad they are launching the center to find and implement culturally appropriate solutions to the challenges of climate change.

The chemistry of dahlia flower colors – Also explains why there are no blue dahlias.

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.

Young female black bears in Asheville, North Carolina, are big, have cubs early – More research needed…it’s still not known what is causing them to be so much bigger and mature early…or if the population is increasing or not. It is clear that there are quite a few bears and lots of opportunity for interactions between people and bears – many not healthy for the bears.

The alarming risks of mixing common drugs – It is a problem that is acute in most elderly patients with good medical care. Their various doctors have gradually built up the medications…and the regime to take them all appropriately becomes daunting. Hopefully it will become best practice to constantly review and minimize drugs that are prescribed.

Work Of First African American Painter With International Reputation Explored – Henry Ossawa Tanner (1859-1937)

Hummingbirds can smell their way out of danger – I was thinking a lot about hummingbirds this past week after my success photographing one at Brookside Gardens.

Praying Mantis – I see these more frequently in the fall…but not every fall. There are so many mantis egg cases, there should be plenty to see; I need to improve my observation skills.

How much energy do we need to achieve a decent life for all? – The most important take away from this study: “energy for eradicating poverty does not pose a threat for mitigating climate change.” That is good news

The lost generation of ancient trees – The ancients are dying….and there are not enough trees old enough to replace them. There are various ways being tried to veteranize younger trees so they can play the role of ancient trees in ecosystems.

Fall Armyworms are Attacking Lawns and Crops on an ‘Unprecedented’ Scale – Hmmm…maybe this is a prompt to reduce or eliminate the grassy portion of the yard.

Mammoth Cave National Park: The World's Longest Cave Is Longer Than Before - 8 more miles mapped bringing the total to 420 miles!

Hand pollination of crops is of major importance – I was surprised that hand pollination is already used for important crops like apple, palm oil and cocoa.

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.

Wind Energy Accounted for 42% of New US Power in 2020 – And solar was 38% of the new energy. And 8 east coast states have large offshore wind projects in the works in the years ahead. Hurray! It’s a good trend and it looks like the slope of the trend will keep increasing for wind and solar (decrease and go to 0 for new natural gas).

How people respond to wildfire smoke -  Another reason to slip on a mask.

Devastating Rain in Tennessee – A map of the change in soil moisture between August 20 and August 21. The floods on August 21 in Tennessee (area circled on the map) killed at least 22 people. I was surprised that there was an area of Illinois (to the north and a little west of the flash flood circle) where the soil moisture increased even more; perhaps that area floods frequently and the area is managed with flooding in mind.

New analysis reveals Vesuvius Victims’ diverse diets – From analysis of Herculaneum skeletons. Men got more of their protein from seafood. Women ate more meat grown on land, eggs and dairy products.

Eye provide peek at Alzheimer’s disease risk – Amyloid plaques can form in retinas of the eye. Does their presence there provide a visible biomarker for detecting Alzheimer’s risk?

Top 25 birds of the week: Wild Birds! – Bird photography…..challenging and beautiful subjects for our cameras.

Have you seen a weasel lately? – There is a suspicion that weasels are in the decline…but the data is circumstantial. These are not predators that have been widely studied. The post points to a role for citizen scientists!

Dispatches from a world aflame – Reviews of two books about the recent fires…and the relation to climate change.

Preemption of Green Cities in Red States – At a time when we need to get serious about addressing climate change – a drive by some states to keep local governments from taking any action. There is a cognitive dissonance between historically arguing for local control then usurping that control when the state government does not agree with it. I like local control but acknowledge that higher up the governance hierarchy could make sweeping changes easier. Perhaps some of these state governments will redeem themselves by quickly taking strong action toward climate change reduction and mitigation – soon. The top issue for me when I vote these days has become climate change!

Climate Change Is The Greatest Threat To Public Health, Top Medical Journals Warn – Another reason that actions to address climate change must be at the forefront of our thinking about the future. Medicine cannot make up for the injury we are making to ourselves and every living thing on the planet.

Entomologists Eradicated the First Asian Giant ‘Murder’ Hornet Nest of 2021 – Includes a picture of the 9 layers of the nest that was carved into an alder tree’s interior.

Turning thermal energy into electricity – It seems like this type of electricity production would have application beyond the military. Even solar panels produce heat and finding a way to automatically harness that into more electricity would be a good thing.  

Climate Change Producing More “Fire Weather” as Far East as Oklahoma – It’s not just the west coast that has a higher risk for fire as the planet gets hotter.

Aztec Pictograms Are the First Written Records of Earthquakes in the Americas – One of the pictograms matched to a 1507 earthquake that coincided with a solar eclipse!

Food systems: seven priorities to end hunger and protect the planet – A thoughtful commentary re ending hunger and improving diets; de-risking food systems; protecting equality and rights; boosting bioscience; protecting resources; sustaining aquatic foods; and harnessing digital technology.

Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk – There was a similar article about pecans a few days ago. I’m glad I like both walnuts and pecans! However – ½ cup is a lot to eat in one day. Usually ¼ cup is considered a serving.

Top 25 birds of the week: Woodpeckers! – I always enjoy hearing a woodpecker in the forest…and its a special tree to see them in our yard. The piliated, downy, and red-bellied woodpeckers are native to our area.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

Gleanings of the Week Ending August 28, 2021

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.

The subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

Nine things you should know about sea horses – The males give birth! Like many creatures right now – they are in trouble from climate change (and overfishing in some parts of the world). Not long ago – I learned that there is a species of seahorse native to the Chesapeake Bay. They live in sea grasses and estuaries…habitats that are in trouble.

Electric cars and batteries: how will the world produce enough? – One of the important steps that needs to ramp up as batteries (and solar cells) reach end of life – is recycling. We need to think about closed loops for the resources required to manufacture future renewables!

New analysis of landmark scurvy study leads to update on vitamin C needs – An example of the research behind how those ‘daily requirements’ of vitamins and minerals were developed. I wonder if more of the values need to go through a validation…how many would change just as the vitamin C requirement did.

Top 10 Grassland Species Across the Globe – The ones we have in the US are Long-billed Curlew, Black-footed Ferret, Pronghorn, Swift Fox, and American Bison.

The multi-billion dollar giants that are melting away – Glaciers. When they are gone…many parts of the world will be drier places. This article is primarily about central Asia…but the situation in South America is similar.

Loss of biodiversity in streams threatens vital biological process – Fungi and bacteria can’t do the decomposition job alone…the aquatic insects (often larvae) and crustaceans are needed too. And the populations and diversity of those organisms in our streams is declining.

Top 25 birds of the week: plumage! – Bird photographs…always colorful and interesting.

Gender revolutions in who holds the purse strings – The study was done in Britain…I wonder if similar (or different) changes are happening elsewhere in the world.

‘Polluter pays’ policy could speed up emission reductions and removal of atmospheric CO2 – A change that could speed up the transition we need to make…if we can somehow overcome the lobbying for the status quo trajectory.

Photography In The National Parks: Fun Fact Photography – This is a kind of photography you can do in lots of places. A little curiosity and a camera…some web searches…a neat cycle of learning/art that can turn again and again.

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.

How your phone battery creates striking alien landscapes – Lithium….needed for batteries that are needed for so many things (not just phone batteries).

Why do house finches love your hanging plants? – These birds are frequent visitors to our feeder. Based on the crowd we are seeing now – they’ve had a very successful breeding season…lots of young birds.

Ultraprocessed foods now comprise 2/3 of calories in children and teen diets – This article prompted me to look at what ultraprocessed foods I am eating…and making some changes. I am keeping the 1st breakfast that includes 90 calories of dark chocolate…but all the other ultraprocessed foods are going to become occasional or rare in my diet.

Tracking the Restoration of the River of Grass – An interview with Eric Eikenberg, President of the Everglades Foundation. There is a lot of work coming to fruition this decade in restoration of the Everglades…some positive news from Florida. It was an encouraging article but after reading the whole thing, it still seems to me that climate change will be a continuing disaster for Florida.

Red Tide Rages Along Florida’s Gulf Coast – On a more pessimistic note about the environment in Florida right now…

Top 25 birds of the week: August 2021 – Birds….so many different kinds to see.

Crawling with crickets: the insect swarm in the western US – Mormon Crickets (really katydids) have population crescendos in 3 of every 10 years in the west. The occurrences are patchy but damaging for some crops.

Music in the American Wild – I watched the Missouri Music at 200 webinar this week and am now looking at more of the concert videos from the ensemble. I’ll post the “Missouri Music at 200” webinar video address (when it is available on YouTube). Of course – live performances would be even better. I enjoyed the Hawaii 2020 project videos already…lots of good views of the island (particularly birds and volcanos!).

The ancient Persian way to keep cool – We’ve had quite a few heat advisory days recently…will probably have an increasing number every summer. The world will need to implement the most efficient strategies available to keep people cool.

Camera Trapping As Mainstream Nature Activity – Little cameras in the wild…they are probably less obtrusive than a human being in the place all the time…but not totally benign in every place.

A roadrunner taking a dust bath wins the 2021 Audubon photography awards – This gleaning list is big on bird photos! This is the first one.

Top 25 birds of the week: Conservation – This is the second. These posts encourage me to get outdoors in areas near my home to photograph birds!

How giraffes deal with sky-high blood pressure – Multiple differences between giraffes and humans when it comes to blood pressure!

Permafrost Thaw in Siberia Creates a Ticking ‘Methane Bomb’ of Greenhouse Gases – The article is about what happened in summer 2020…made me wonder about what is happening this summer in Siberia. This along with the fires that seem to be worse each season are signs that climate change is happening faster than anticipated…that the models might be optimistic rather than realistic.

Plastic, the Trojan Horse – A study that found plastic accumulation in foods may be underestimated. Not good.

Smoke Across North America – Lots of fires this summer. My husband told me that the local astronomy club has cancelled several nights they’d planned for observing because no stars were visible through the haze here in Maryland.

How the sun affects our skin – An infographic about vitamin D, sunburn and skin cancer.

This catfish doesn’t just move on land, it reffles – Plecos – from the aquarium trade – are now invasive in warmer waters in the US. They do have an interesting way of moving on land (videos of their reffle)…..this means if found/caught they shouldn’t be left on the bank to die (since they will easily move back to the nearest water). The article didn’t say what to do with them (presumable kill them).

Drought, Heat Taking a Toll on National Parks in Southwest – I’ve enjoyed so many of the parks mentioned in this article – Saguaro, Grand Canyon, White Sands, Petrified Forest. It has always been dry there…but now it is getting drier and hotter.

Take a Virtual Tour of Artworks Inspired by Efforts to Preserve Plant Biodiversity – A virtual site of an exhibit not at the Royal Albert Memorial Museum and Art Gallery in Exeter, England. Watch the 5 minute video about the site….then enjoy the exhibit here.
