Pregnant women are exposed to cancer-causing chemicals in dishware, hair coloring, plastics, and pesticides, study reveals – Something else for pregnant people to be anxious about. I wish these studies had a stronger component about how to reduce exposure, but it seems that the problematic chemicals are very pervasive.

The U.S. diet is deadly. Here are 7 ideas to get Americans eating healthier – These ideas a geared to making it easier for individuals to make healthier choices. Right now…it seems that the push is toward unhealthy food choices.

Cool planning for a hotter future – Actions we need to take to achieve the ‘late century rapid action’ maps.

Low physical function after age 65 associated with future cardiovascular disease – Individuals were assessed for walking speed, leg strength, and balance….and the scores were more predictive of cardiovascular disease risk than the traditional risk factors that work for middle-aged people (high blood pressure, high cholesterol, smoking or diabetes).

On “Trash” Birds: Rethinking How We Label Common Species – There is no such thing as a ‘trash’ bird or any species. They are all just part of our world!

Can These Lights Make Crosswalks Safer for Pedestrians Distracted by Their Phones? – People shouldn’t be walking while looking at their cell phones more than where they are headed….but they do and maybe Hong Kong is ahead of us in developing a solution to reduce tragedies.

Is Breadfruit the Climate Change-Proof Food of the Future? – Not a food I know anything about…it’s not in our grocery stores yet. I looked at some recipes and it seems like it would be a versatile addition to our diet.

Archaeologists Call on UNESCO to Protect the Hagia Sophia – It’s sad when pieces of architectural history are not maintained. Hopefully this call will help organize what is needed to preserve Hagia Sophia.

Heat waves + air pollution can be a deadly combination: The health risk together is worse than either alone – There are ways to stay safe…but it is not possible for everyone all the time. We need to address the underlying issues for the health of everyone. Often – addressing air pollution also is step in a good direction of climate change as well.

See the Incredible Sunflower Superbloom in North Dakota – Wow! Maybe a trip to North Dakota some July/August should be added to our list of road trips we want to make.

We asked children how they experienced poverty. Here are 6 changed needed now – This was a study done in Australia. I wonder how applicable these findings are around the world.

The identical twins who discovered their secret sibling – An adoption agency that separated twins for adoption in the 1960s…and the researchers that were part of that process. Fast forward to 2022.

Heat wave reveals 17th-century English gardens – Longleat Gardens….a whisper of the past…from before the transition to natural parkland in the 18th century.

Is this the end of DC’s most-beloved hidden landmark? – I’ve never seen (or known about) the Capitol stones in Rock Creek Park but I’ve noticed the old columns dating from the same period that are in the National Arboretum. They are certainly a landmark!

Painted Bunting: The Fun of Local Bird Quests – I remember seeing some painted buntings at a Florida National Wildlife refuge and an indigo bunting under my bird feeder in Maryland. They are special birds!

Colorful solar panels could make the technology more attractive – Color is a lower priority than efficiency for me, but it could be very important in some applications.

A Beginner’s Guide to Butterfly Watching – I wish there were more butterflies to watch! It seems like every year there are fewer of them around.

Taming Tomorrow’s Wildfires – There is a wildfire burning somewhere in the US all the time recently. It’s important that we make changes to reduce their devastation.

New drug candidate fights off more than 300 drug-resistant bacteria – Antibiotics have been around for my whole life…but there is always the discomfort that more bacteria are becoming resistant…and there could come a time that the pre-antibiotic killers will beginning killing people again. I’m glad there are new drugs in development to take up the fight.

Olmec contortionist Reliefs Uncovered in Mexico – Artifacts from a civilization known for colossal head sculptures….hints of their culture.

Photographer Creates Mesmerizing Flight Trails of Winged Creatures as a Meditation on Time – Action in the air (composite images).

The crab invading the Mediterranean Sea – The blue crab is native to the Indo-Pacific but reached the Mediterranean Sea in 1898…about a decade after the Suez Canal opened. With temperatures in the Mediterranean rising with climate change, more the crab larvae are reaching adulthood. Now the Tunisians are trapping and processing crabs for export. Other places in the Mediterranean are also harvesting and processing invasive species: Cyprus has local restaurants serving lionfish and jewelry/artwork is created from their soft colorful fins. Rabbitfish have also become a commercial fish. But will these measures be enough to rebalance the ecosystems and improve biodiversity?

Where did pigeons come from? – A bird that we see frequently….that humans have taken around the world…and it likes to stay near us!

Understanding the new Federal tax credit for electric cars – Why does it always have to be complicated?

Is dark chocolate really good for you? – Of course! I like my high % cocoa squares first thing in the morning…my perfect 1st breakfast.

The dangers of working in hot weather – Glad to see some attention on this…and a sharing of practices that can help while still getting work done. With the high level of employment (and often challenges hiring new people), businesses should have an elevated interest in keeping their workers healthy and productive.

 Home solar + storage will get a boost from the recent climate bill, claims Bloomberg – Hurray!

Banana peels make sugar cookies better for you – Ok – so maybe I should never put banana peels into the compost. I’d rather use them directly in recipes like Banana Peel Cake rather than making them into flour. I think I’ll start washing them and putting them in the freezer when I eat the fruit….process them as I need them for baking!

Meet the world’s largest land crab – And also learn a bit about Palmyra Atoll.

Is the river of grass really a river? – A little history…and discussion of what makes The Everglades a river (an unusual one!).

What a decade of Curiosity has taught us about Mars – Looking for signs of life.

Zion National Park, Utah – A view of the park from the International Space Station. A piece of trivia from the post: Cyanobacterial blooms are a threat to hikers and wildlife – exacerbated by intense summer heat.

Air pollution, including during wildfires, shows ill effects in children -So many questions popped into my mind as I read this article: Does keeping children indoors with modern air conditioning/heating filtered air help? Further air purification required? The children in the study were 9-11 years old; are some of the markers also indicators of stress they may have developed knowing there were wildfires?

Ultra high-speed photography captures hidden human figures in moving water – Eye candy

Heat pumps prove themselves during a harsh Maine Winter – Modern heat pumps do the job even at -21 degrees in Maine!

Neolithic Watermelons may have been valued for their seeds – Snacks! And now most watermelons we buy in stores doen’t have seeds at all!

Nahuku Lava Tube in Hawai’i Volcanoes National Park Closed to study its stability – Also known as Thurston Lava Tube. I walked through it when we were in Hawaii several years ago.

Vitamin K prevents cell death: New function for a long-known molecule – Important for blood clotting….but new research shows it is also a potent antioxidant that ameliorates cellular iron’s role in cell death (ferroptosis). There will probably be a lot of subsequent research following up this finding.

The science of making cheese – Infographic that shows the 4 steps: acidification, coagulation, reducing moisture content, and maturation.

The mysterious inner life of the octopus – Interesting article….or just look at the pictures!

An effective new treatment for chronic back pain targets the nervous system – A 12-week course of sensorimotor retraining had a positive effect and participants reported improved quality of life one year later (i.e., the relief was lasting). Hopefully the results can be replicated, and the treatment applied to a broader population. There are a lot of people with chronic back pain!

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior – Hard to resist a cat story!

Millions of Americans have long COVID. Many of them are no longer working – 4 million full-time equivalent workers out of work because of long COVID (conservative estimate…and that 2.4% of the US working population). There is a push to provide accommodation in the workplace but some of the symptoms are so severe that the person cannot perform the work they did before and maybe too disabled to work at all. No wonder unemployment is low, and some jobs are not finding applicants. Because long COVID is new, it is unclear when, or if, this population will recover enough to re-enter the workforce.

Arche Roach: the great song man, tender and humble, who gave our people voice – An obituary – and history of aboriginal people in Australia over the past century or so.

The promise and danger of Scotland's bog – 80% of the UK’s peatlands are degraded and in deteriorating condition. They store a lot of carbon…motivating restoration efforts. It takes decades to reverse damage done in a short time by a few ditches and a grid of planted saplings.

New molecule may prevent age-related diseases and increase life expectancy and wellness – A group of molecules that enable cells to repair damaged components has been identified….and efficacy was demonstrated in a model organism. The researchers and Hebrew University’s tech transfer company are moving toward pre-clinical studies.

Parts of the moon have stable temperatures fit for humans – Pits and caves that stay roughly 63 degrees Fahrenheit! There are still big challenges for living on the moon: growing food and finding sufficient oxygen, for example

Coming wave of opioid overdoses 'will be worse than it's ever been before' – Fentanyl and carfentanil…combined with methamphetamines and cocaine. The accelerated rates of overdoses are happening everywhere according to a Northwestern Medicine study.

Inside King Tut’s Tomb – New research using the tomb walls to understand the real-world turmoil cause by the death of the young king.

Cocoa shown to reduce blood pressure and arterial stiffness in real-life study – Cocoa flavanols only decrease blood pressure if it is elevated! I enjoy my morning dark chocolate (70+% cocoa) squares…a healthy way to begin the day!

Ten Little Celebrations – July 2022

Like June, July was a high stress month because of our move to Missouri - but with much to celebrate.

Family holiday gathering. The 4th of July was our first ‘holiday’ celebrated in Missouri…having my daughter and son-in-law over for veggies with hummus, steak, corn-on-the-cob, and watermelon.

An easy drive home…and being home again. The drive to Maryland and back was long…but once back in Missouri we celebrated only having one house again…and clearly it was ‘home.’

Dragonfly posing for pictures in our back yard. We seem to have more dragonflies around our yard in Missouri and I celebrate every time I manage to photograph one. The closer location to a pond might be why we are seeing them more frequently.

Being indoors during the hot part of the day. Every day that gets above 100 degrees is one I celebrate being indoors! We’ve had quite a few hot days this July – more in Texas than Missouri.

Getting boxes cleared from the garage. Once the pile gets annoying we make a trip to the recycle center – celebrating that it is convenient and that the garage is clear…until the boxes pile up again.

Springfield Botanical Garden. This is probably my favorite place for a walk in Springfield. It is a place I want to see again and again…through the seasons…finding a little celebration every time.

Little fixes completed. There were some little fixes identified when our Missouri house was inspected. I celebrated when they were completeed – particularly the one in the basement bathroom (since my office is also in the basement).

Josey Ranch green heron and ducklings. I only walked around the place once because it was so hot while I was in Texas…but celebrated the birds that I saw there (blog post coming soon).

Getting car inspected/registered…and MO driver’s liscense. It has been a very long time since I moved to a new state and I anticipated a lot of red tape. I was relieved when we managed to get the cars registered, our driver’s liscense….and register to vote…celebrated when they were all done…and glad that the process was not as difficult as I thought it might be.

Establishing the compost circle. I celebrated finding edging that was high enough to make a circle  to hold the small amount of compostable material I have from my kitchen….just in time to start it off with watermelon rind!

Gleanings of the Week Ending July 30, 2022

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.

Furs from Danish Viking Burials Analyzed – Proteins extracted from animal furs found in 6 burials. The accessories/furnishings were domesticated animals. The items of clothing were wild beaver, squirrels, and weasels. The beaver furs were not native to the area so were probably luxury furs obtained by trade.

More Energy on Less Land: The Drive to Shrink Solar’s Footprint – Good ideas…if we must use agriculturally productive land for solar panels. I’d like to see cities with high density solar panels that generate electricity close to where it is needed (i.e., short distance between generation and use). Hopefully that is happening in parallel with the solar development described in this article.

Moths are unsung heroes of pollination – The study was done with red clover…but probably applies to a broader range of plants. Moths are active during the night so have not been as easily observed as pollinators that are active during the day. The work was done with time lapse cameras.

Electric School Buses! – A blog post about the US Department of Energy’s ‘Flipping the Switch on Electric School Buses’ series. There are lots of communities that have been exploring making the transition and I am hopeful that it will be an escalating trend. I always cringed at the fumes that were so obvious when the buses arrived/departed from schools as I was growing up and when my daughter was in school. It would be good for the planet and good for children’s lungs to eliminate the school bus as a source of air pollution!

The habits that help prevent allergies – Studies that are improving our understanding of why allergies are increasing in the children….and strategies for addressing the problem. Evidently the time between 4 and 11 months is very important.

Harm from blue light exposure increases with age, research in flies suggests – Not good news. Maybe the default setting on our ‘screens’ (phones, computers, television) need to reduce blue light rather than it being a setting that everyone must intentionally set. And why don’t LED manufactures offer bulbs that are not so blue shifted?

Giant Snails take over Florida’s Gulf Coast - It is not the first time…probably won’t be the last. These snails are native to Africa and this the third time Florida has battled an invasion.

Water resources to become less predictable with climate change – The study focused primarily on areas that rely on snow for all or part of their water supply. Some of those areas are already relatively dry…and the populations are large enough that the unpredictability of water resources will be very problematic.

The best way to brush your teeth – This is going to take some practice to break old habits. I learned to brush my teeth a long time ago and probably am too sloppy even doing it the way I was taught!

New thought on Cahokia’s ancient wetlands – A large flat rectangular area that was previously thought to have been used as open, communal space might have been under water most of the year!

Unique Aspects of Days - July 2022

Settling into our new home in Missouri is still prompting unique aspects of our days!

1st doctor’s appointment in Missouri. Getting medical records transferred from a specialist in Maryland to a new specialist in Missouri was a first for me…and I was pleasantly surprised that it happened so easily and that the new doctor continued the monitoring/treatment as I expected.

Callery Pear to the recycle center. It was a unique experience to discover a pear tree growing in a crepe myrtle in a front flower bed of my new house. I cut it down…discovered it had thorns…and was very pleased to get it cut up enough to fit in the back of my car and then to the recycle center yard waste bins without injuring myself. It was an experience I hope is unique!

Unpacking the art glass. I packed it but my husband unpacked it. There was a joy in packing and unpacking the beautiful pieces….savoring them individually and then again as a whole in the display cabinet. We left 2 pieces that are on light stands out on a desk beside the piano to act as ‘night lights’ in that part of the house. It has been over 25 years since we enjoyed the glass the way we did in July.

Making a compost ring with cedar edging. I bought two sections of edging made with 3-6 inch vertical lengths of cedar branches and formed a circle to hold my kitchen scraps and soft yard waste under one of our pine trees. There is not enough material to require a bigger compost bin so this is a relatively unique solution. I’m not sure whether I will move the ring once the compost is deteriorating enough to continue as a pile without the ring or ready to spread out. There is space to move the ring and start another collection nearby.

Finding the camera battery charger. It seemed like there were about 5 times this month where we came close to panic because we couldn’t find something we needed in our new home. The one that had me most worried was not knowing where the charger was for my camera battery; luckly I found it after an hour or so of hunting through boxes. Now that we have unpacked most of the boxes, it is less likely to occur…making this particular kind of anxiety unique to July 2022.

Forgot my toiletries. I travel frequently enough that I rarely forget anything I need…but I did for our trip back to Maryland for the closing on our house there! The compartment bag for toiletries was left hanging on the bathroom door in Missouri. I quickly bought essentials…glad this event was unique in my travels.

Hot and dry Josey Ranch lake. The lake at Josey Ranch near where my parents live was lower than I’ve seen with deep cracks where there is usually water or mud. The cattails area is dry and other plants are taking over. I hope this is unique and not what it will be like every summer from now on in Carrollton TX.

Hummingbird moth. I was surprised…glad I had my camera with me…when I spotted a hummingbird moth at the Springfield Botanical Garden. They are fun insects to watch and I always feel priviledge to see even one a year.

Hummingbird outside my office window…on the crepe myrtle. I looked out my window one morning and saw a hummingbird checking out the crepe myrtle outside my office window. It was the first I’d seen in our Missouri yard.

Missouri watermelon at the Carrollton (TX) Walmart. I noticed that the watermelon I bought for my parents in the Carrollton Walmart had been grown in Missouri…and discovered when I got home to Missouri – the watermelons in the Walmart were from Missouri too!

Watch a Deep-Sea Squid Carry Hundreds of Pearl-Like Eggs – A video from the Monterey Bay Aquarium.

It’s a trap: managing cowbirds to save songbirds – The strategy of trapping cowbirds (a brood parasite) to help endangered songbirds along the Santa Clara River in Southern California has evolved to reduce harming other species and cost less.

Electric vehicle buyers want rebates, not tax credits – Of course….immediate rebates rather than waiting for months to get a tax credit are much more appealing.

Urban waterways: discovering the hidden beauty of a Jersey River – River restoration across the country…with the Cooper River story in more detail.

Universal influenza B vaccine induces broad, sustained protection – A new kind of vaccine….using nanoparticles. Perhaps this new technology will lead to an effective universal flu vaccine.

The sustainable cities made of mud – A little construction/architectural history….that could be applied more often.

10 Weird Australian Marsupials You’ve Never Heard Of – So many unusual animals…Australia has more than just kangaroos and koalas!

Cancer probably killed world’s first known pregnant Egyptian mummy – 2,000 years ago a young woman died…and was mummified. The Warsaw Mummy Project has determined that she was pregnant – the fetus was ‘pickled’ in the highly acidic and low oxygen environment of the mummified womb – and the woman probably died of nasopharyngeal cancer.

More Electricity from Wind and Solar than Nuclear for 1st time in USA – Hurray! Wind and solar accounted for over 25% of the nation’s electricity in the first 4 months of 2022!

Loss of male sex chromosome leads to earlier death for men – What? Y chromosome loss happens in 40% (estimated) of 70-year-old men. The loss occurs primarily in cells with rapid turnover, such as blood cells. And it might lead to heart muscle scaring…and then heart failure.

The silent danger of gum disease – More reasons to sustain regular dental checkups….and for dentists to be vigilant.

The Milkweed Gang – Milkweed attracts quite a few insects…even if it is an island surrounded by invasive plants!

New species of giant waterlily is the largest in the world – It has been growing in Kew Gardens in 177 years and in a herbarium in Bolivia for 34 years….always assumed to be the well-known species of giant waterlily named after Queen Victoria. The leaves can grow up to 10 feet wide…and support at least 176 pounds!

Toads surprise scientists by climbing trees in UK woodlands – Even when we think we know a species well…there are still surprises!

This New Species of Carnivorous Pitcher Plant Traps Its Prey Underground – In the rainforest of Borneo at elevations of 3,600 – 4,265 feet.

Ozone Hole — New, Large, Constant Ozone Hole — Appears Over Tropics – 7x larger than then Antarctic ozone hole!

Unlocking the secrets of the ancient coastal Maya – More than a decade of interdisciplinary work increasing the understanding of how these people lived and responded to rising sea levels and changing political/economic systems. And still more to be learned.

Get a Sneak Preview of the 2022 Bird Photographer of the Year Finalists – Capturing birds in action…rather than portraits.

Invasive species taking over some American forests - Amur honeysuckle (a shrub from Asia) is a big culprit. Callery Pear (the ‘wild’ version of the Bradford pear) is a close second.  I just cut down a Callery Pear that was growing in the front bed of my new house in Missouri…almost obliterating a crepe myrtle! Other foreign species that have become problematic: porcelain berry, tree of heaven, winged euonymus, European buckthorn, Oriental bittersweet, common privet and lesser periwinkle...Norway maple, Amur cork tree and white poplar along with herbaceous species such as lesser celandine, garlic mustard, Japanese knotweed and Japanese stilt grass.

A Surprisingly High Number of Wildfires Are Caused by Electrocuted Birds – Awful….good that there is a way to reduce the carnage…at less cost than the consequences of the fires.

Rural areas near coast will bear the brunt of US sea-level rise – Analysis focused on the Chesapeake Bay…marshes forming where forest and farmland is today.

Once-Common California Bumble Bees Have Gone Missing – The survey did not find the formerly abundant Western bumble bee. The last statewide survey was conducted 40 years go…and a lot has happened in that time: habitat loss, pesticides, and climate change. None of the species were doing well. Big problem – since bumble bees help pollinate $3 billion worth of crops in the US each year (including tomatoes, peppers, and cranberries).

Scientist war of links between soil pollution and heart disease – The author of the study commented: “Until we know more, it seems sensible to wear a face mask to limit exposure to windblown dust, filter water to remove contaminants, and buy food grown in healthy soil."

Alaska Ablaze – 5,000 lightning strikes…dozens of wildfires.

How to turn your garden into a carbon sink – Turning more yards into gardens…with more diverse plantings….a few more trees. Sometimes going a little wild is a good thing!

Pollen and Heat: a looming challenge for global agriculture – heat is a pollen killer for canola, corn, peanuts, and rice. It is becoming more important than ever for crops to bloom before the temperature rises…and it is getting more challenging as multi-day stretches of excess heat are becoming more common early in the growing season.

The life of a solitary bee – There are as many as 4,000 bee species in the US….and most of them are solitary. 98% of the native bee species in the US are solitary.

What if all roads went underground? – Thought provoking…wish there were ways to make it a more practical solution since the aesthetics of a world that has more natural surfaces (rather than roads) is very appealing.

Endangered Whopping Crane Hatches at Smithsonian National Zoo Site – The egg was found on an abandoned wild nest in Wisconsin and given to a pair of whooping cranes in the zoo that had produced 2 infertile eggs. The live egg was put into their nest on 5/18 and the baby crane hatched on 5/26!

BLM, Forest Service, Five Tribes of The Bears Ears Commission Commit to Historic Co-Management Of Bears Ears National Monument – Wishing the best for this endeavor.

Antarctica’s ‘Doomsday Glacier’ melting at fastest rate in 5,500 years – Thwaites Glacier (nicknamed the Doomsday Glacier…Florida-sized) and Pine Island Glacier were studied. The ice shelf holding the Thwaites Glacier could collapse withing 3-5 years.

Finding mini frogs: these aren’t babies, they’re just little – And they hatch as frogs…no tadpole stage. They live in leaf litter…humid and moist but not near water.

New safe-sleep guidelines aim to reduce infant deaths – New guidelines have been coming out from time to time at least since my daughter was born over 30 years ago. When she was a baby, the recommendation was for babies to sleep on their tummy…very different from these current guidelines.

2021 Share the Experience Photo Contest (National Park Foundation) Winners – Special places…full of great experiences.

Los Angeles becomes the latest city to hire ‘chief heat officer’ – Miami and Phoenix as well as cities in other countries (Athens, Greece; Freetown, Sierra Leone; Monterrey, Mexico; Santiago, Chile) have similar positions.

One in 500 men carry extra sex chromosome, putting them at higher risk of several common diseases – A surprising result…most of the men were unaware they carried an extra X or Y chromosome. Those that are XXY had higher chances of reproductive problems. Both XXY and XYY individuals has higher risks of type 2 diabetes, deep venous thrombosis, pulmonary embolism, and chronic obstructive pulmonary disease.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

“Legacy Pollution” to be cleaned up in seven national parks – I am pleased that it is being cleaned up…chagrined that taxpayers are paying for it rather than the oil companies.

Dandelion chemistry: diuretics and the tires of the future – Redeeming qualities of what we normally consider weeds that are menace! I’ve come to appreciate them more over the years because they are edible (my grocery story has the leaves in their organic section occasionally) and their roots are deep enough to hold soil better than turf on a slope.

Infant formula: the superfood you never think about – One of my grandmothers discovered she was unable to breastfeed her babies….and that was well before commercial formula was available. Whatever recipe she used to create ‘formula’ worked. I suspect that one of the ingredients was evaporated milk. Her 9 children thrived…some into their 90s. What happened in the US recently with infant formula reminds us how dependent we are on modern technology that has become increasingly complex…and sometimes without enough redundancy/alternatives when failures occur.

Ancient ochre mine uncovered in Wyoming – Around 13,000 years ago, Paleoindians mined hematite at the site…and used it to produce red ochre.

Photos of the week – May 27, 2002 – Spring prairie flowers/seeds from the Prairie Ecologist.

What can and can’t be recycled – Thinking about recycling….now that I am moving to Missouri, I need to figure out the rules for curbside recycling. I already know there are some differences from Maryland.

Type 2 diabetes accelerates brain aging and cognitive decline – A scary result since there are so many people with type 2 diabetes….and currently doctors don’t have brain based biomarkers for type 2 diabetes or treatment strategies that target neurocognitive declines.

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.

Under Water and Under Pressure – 100 national parks are coastal…and are already taking action to mitigate sea level rise.

Where do ‘Hawaiian box jellies’ come from? – Evidently the box jellies appear close to shore like clockwork 8-10 days after full moon. This research reveal that the jellies are spawning during that time…and where they are when they not close to shore. This is important for providing better information to ocean swimmers and beach goers…trying to avoid stings. Another benefit…learning to keep the food web balanced to control box jelly numbers in Hawaii and other tropical localities.

Stirring up a mid-Atlantic bloom – Lots of nutrients flowing into the water from the coastal watersheds during spring rainstorms.

Vancouver requires gas stations & parking lots without EV chargers to pay $10,000 per year – Interesting idea…hope it increases the number of chargers and the trend to EVs!

Photography In The National Parks: More Favorite Places For Photography - We’re not going to be traveling to any of the western parks near term….so I enjoyed them through these photographs: Crater Lake, Redwood, Yosemite, Great Basin, and Lewis and Clark (Washington state portion).

Maya tooth treatments may have prevented infection – In the Mayan world - holes were drilled to attach stones to teeth; an analysis of the sealant used for 8 teeth from across the Maya empire (AD 200-900) revealed that most sealants included ingredients from pine trees that have been shown to fight the bacteria that cause tooth decay.

Top 25 birds of the week: Forest Birds – I always like bird pictures….

Scientists recreate Cleopatra’s favorite perfume – Recreating Mendesian perfume…the result so far has been a strong, spicy, faintly musty scent that tended to linger longer than modern fragrances…with ingredients like desert date oil, myrrh, cinnamon, and pine resin.

Grand Canyon of Texas – I remember (tent) camping in Palo Duro Canyon in the 1970s on the way to Colorado…being very hot and worried that our tent was too close to a red ant bed! At the time, I didn’t realize that it is the second largest canyon in the US (behind Arizona’s Grand Canyon).

Why humans get less sleep than other primates – A different type of sleep research…teasing out the differences in sleep of humans and other primates….and between non-industrial human populations and industrial human populations. It turns out that in the human populations…the hours of sleep are about the same but the perception of getting enough sleep is higher in the non-industrial populations than the industrial ones!

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.

Major infrared breakthrough could lead to solar power at night – A very small amount of energy was produced in the test…more research required for practical application.

Restoration Reveals Engravings in Egypt’s Temple of Esna – Follow the link at the top of the post to see a few more pictures of the restored engravings.

What we are still learning about how trees grow – A new study finds that tree growth is limited by cell growth rather than photosynthesis which has been assumed to be the limiting factor previously. The models that predict how much carbon forests can absorb need to be updated.

Spring Flowers are Blooming Earlier in Greater Yellowstone – The recovery of detailed records made in the 1970s by Frank Craighead of when flowers bloomed is helping document changes…help restoration planners determine the best seed mixes for native plants…try to mitigate the impact of climate change.

Cutting air pollution emissions would save 50,000 US lives, $600 billion each year – Yet another reason to take actions to dramatically reduce air pollution.

Traces of an ancient watery world in Capital Reef – Satellite views of Capitol Reef National Park…and the story in the rocks.

Prehistoric feces reveal parasites from feasting at Stonehenge – A piece of trivia: beef and pork were spit-roasted or boiled in clay pots but the evidence of particular parasites in coprolites reveals that liver and lungs from an infected animal were consumed raw or undercooked.

Vangelis, famed film composer and synth pioneer, dead at 79 – I remember going to see Chariots of Fire when it first came out in the early ‘80s….and the unforgettable music. This obituary post includes a link to a YouTube video with the music.

How cranberries could improve memory and ward off dementia – I like cranberries…but eating a cup (equivalent) per day is a lot. In the study they used cranberry powder.

More heat, more drought: New analyses offer grim outlook for the US west – The latest seasonal outlook projects the drought to continue across virtually the entire American west through the summer. New research suggests that Colorado, Utah, and Wyoming will increasingly look like the Southwest as temperatures continue to rise.

Amazing Photo of Wisteria Trees Looks Like a Fireworks Display – Pictures from Japan’s Ashikaga Flower Park.

New Mexico Wildfire Spawns Fire Cloud – A pyrocumulonimbus cloud formed; the vertical plume reached the tropopause….an altitude of about 12 kilometers.

Heatwaves are altering our everyday lives – The new normal but we aren’t very well prepared for it; there are some obvious adaptations that are needed – particularly to electrical networks. No one wants infrastructure to fail at a critical time.

Well-preserved iron age arrow discovered in Norway – The arrow was recovered from a glacier…iron arrowhead, sinew, tar, thread, shaft, and feather fletching was preserved. It is about 30 inches long.

Rigid waterproof coating for paper aims to reduce our dependence on plastic – Interesting…would be great if it could speed the transition away from plastic for food packaging particularly. The article said the chemicals break down over time into harmless components…but didn’t say how long that took.

Chemicals that linger for decades in your blood – So many chemicals introduced in my lifetime are probably still in my blood. I can remember the spraying of DDT for mosquitoes in the ‘60s….one instance particularly of the straying truck going down the farm road near my grandparents house as we played in the back yard. How much of my exposure do I still have…did I pass along to my daughter?

Ultraviolet light reveals radiant hidden beauty of flowers – A project during the COVID-19 pandemic…beautiful results.

Archaeologists Unearth 3,000-Year-Old Giant Statues in Sardinian Necropolis – Over 7 foot tall…with almost emotionless expression, blocky nose and deep-set eyes. The two found most recently were boxers but about two dozen others have been found since the mid-1970s: 16 boxers, 4 archers, and 5 warriors.

Top 25 birds of the week: May 2022! – Bird appreciation….a source of beauty in the world.

Disparities in natural gas leak prevalence in US urban areas – Why can’t pipeline companies do better…not wait around until regulation requires them to do it? We should be more critical of the companies that they are not actively reducing leaks in their pipelines.

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 human brains were bigger 3,000 years ago – Some possible explanation: human populations reached a large enough size to share/divide labor and knowledge with others, writing….however, brain size/IQ relationship is not deterministic.

Operating rooms are the climate change contributor no one’s talking about – The health care industry accounts for 8.5% of all greenhouse gas emissions in the US. Operating rooms represent 70% of waste in hospitals and 3 to 6 times as much carbon as the rest of health systems.

Where tornadoes strike most frequently is changing – More erratic tornado activity and the broad impacts of climate change.

Do you have a lost twin? - The rate of twins among live births is only about 1.3%. But as many as 12% of all naturally conceived pregnancies may begin as twin pregnancies.

Wild fox kills 25 flamingos and a duck at National Zoo – We see foxes in our neighborhood. They seem to have adapted to the suburban environment. This one was very efficient to kill 25 birds, though.

A 10,000-year history of geo-ecological change in Yellowstone’s lower geyser basin – A study using a 26.5-foot core from Goose Lake.

US could cut transport emissions by 34% b 2030 – The current trend will reduce emissions by 19% but a bit more focus would provide a bigger reduction.

Garbology: How to spot patterns in people's waste – We’ve been getting rid of a lot as we prepare to move. I try to do as much as possible via donations and recycling…but there is still a lot going in the trash. Some of it came from Texas with us back in 1983…and was still in the same box!

6,000-Year-Old Slate Rings May Have Symbolized Relationships – Friendship rings? Careful analysis revealed the rings had been intentionally broken…and shared (i.e. pieces of a ring were found in two separate burial sites).

How Taipei discovered an active volcano on its doorstep – Disconcerting. Even of there is some ability to provide early warning of an eruption…could the city be abandoned quickly enough?

A Watershed Moment: Key Findings About Potential Drinking Water Contamination – The sources of contamination are varied….but the list of primary sources is relatively short.

Better residents’ health after switch to electric buses – A study from Sweden. Improved health is a benefit of electrification of transportation!

Should people get rid of their yards? – Somewhat depressing conclusion: “Most people would rather make an aesthetic choice with their lawns than an environmental one.” My plan is not to eliminate the yard in my new house but to minimize it over time with the addition of bushes along the fence and extending beds around trees and around the house.

We talk the fastest growing green jobs with LinkedIn Sr. Editor – The “job vs the environment” is changing. The “green economy’s ability to expand job opportunities is too significant to ignore.” This growth in green jobs is like the 1970s for computer related jobs – a lot of new types of jobs and many of them will extend for the duration of a career starting now.

Discover the Microscopic Wonders of Olympus’ 2021 Image of the Year Awards – Taken with light microscopes…lots of finesse preparing the specimens.

Known to be toxic for a century, lead still poisons thousands of Midwestern kids – Two things I learned from this article about the state I am moving to: Missouri is one of the four states in the Midwest that is struggling to alleviate lead poisoning in children…and it is the number one producer of lead in the US. Hope they are making progress.

Top 25 birds of the week: terrestrial birds – Always enjoy the bird photographs! This group includes a roadrunner….a bird I always associate with Texas but the photograph was taken in California!

Tests indicate bronze age daggers had a practical purpose – Evidently the daggers were thought to be ceremonial objects prior to this analysis.

Should we be eating three meals a day? – The number of meals may not be as important as consistency….and giving the body a long enough ‘fast’ time to rest.

The Great Barrier Reef through Time – Landsat Images used to illustrate recent research on the growth of the reefs as the ocean changes. Evidently the reef has been more resilient to past sea-level and temperature fluctuations than previously thought….but increased sediment input has been a bigger problem.
