Gleanings of the Week Ending June 1, 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.

How Storm King Art Center Became One of World’s Top Sculpture Parks – Adding to my list to consider seeing if I travel to New York (state).

Dirt Cheap Batteries Enable Megawatt-Scale Charging Without Big Grid Upgrades Right Away – Hope the technology trend continues…that this idea helps us transition to more electric trucks and other vehicles.

Extreme Birding: Shorebirds at the Sewage Lagoon – Maybe a great place for birding….if you can stand the smell. The same thing happens at landfills.

The human brain has been shrinking – and no-one quite knows why - The brains of modern humans are around 13% smaller than those of Homo sapiens who lived 100,000 years ago. Exactly why is still puzzling researchers. I was a little surprised that the authors did NOT consider the challenge of birthing babies with larger heads (i.e. until C-sections allowed mother and baby to survive if the baby’s head was too large, both mother and baby died) which would result in natural selection of genes for smaller heads.

Climate change is most prominent threat to pollinators - Pollinator populations are declining worldwide and 85% of flowering plant species and 87 of the leading global crops rely on pollinators for seed production. The decline of pollinators seriously impacts biodiversity conservation, reduces crop yield, and threatens food security. Changes in water and temperature associated with climate change can lower the quantity and quality of resources available to pollinators, decrease the survival of larvae or adults, and modify suitable habitats.

The deep ocean photographer that captured a 'living fossil' – In 2010, Laurent Ballesta was the first diver to photograph a living coelacanth. In 2013, Ballesta and his team returned and encountered multiple coelacanths, spending up to half an hour in their presence. Thanks to Ballesta's work, we now know the coelacanth is among the longest-living fish species, with a lifespan of around 100 years, and has one of the slowest life histories of all marine fish – so, like deep-sea sharks with a reduced metabolism, the coelacanth grows slowly, taking as long as 69 years to reach sexual maturity, and with a gestation period of around five years.

Under stress, an observer is more likely to help the victim than to punish the perpetrator - It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender.

Stunning Aerial Photos Capture the Abstract Beauty of Iceland’s Glacier Rivers – Iceland….blue.

These tricks make wind farms more bird-friendly – Migratory birds can crash into wind turbines…but there are ways to reduce the carnage: adding high visibility reflectors and spirals to cables, not building wind farms in flight paths, painting one blade on each turbine black (or stripes of black on each blade), and sound.

Swarms of miniature robots clean up microplastics and microbes, simultaneously – Interesting idea. While the bots were decontaminated and reused…they were not as effective…so more work is needed.

Zooming – May 2024

/

After collecting the images I wanted to feature this month, there seemed to be more distinct reasons for why the amount of zoom was used.

One image – from the Anthony Chapel at Garvan Woodland Gardens – was composed to capture the pattern of glass in the ceiling.

5 images were composed to get a near macro view of flowers and water droplets without being very close to the subjects.

The zoom was used to fill the frame in 8 of the images. It works in almost every situation! Flowers and landscapes with structures outdoors as well as museums and nature center exhibits are seen below.

Probably the rationale for zooming I enjoy the most is when the camera allows me to ‘see’ better than I would with just my eyes. There are 7 images in this category this month: a close up of a peacock and some flamingo feathers at Dickerson Park Zoo in Springfield, Missouri; tiling on a bathhouse dome and a magnolia flower in a large tree overhanging the street in Hot Springs, Arkansas; an ebony jewelwing on a fern, a fairy house and a Ouachita Map Turtle at Garvan Woodland Gardens.

Sometimes I remember the rules and zoom to position the subject along one of the lines…to the left or right of center in lieu of switching to a portrait orientation and filling the frame.

I am savoring my favorite zoomed images of May 2024.

Ten Little Celebrations – May 2024

/

May 2024 was full of little celebrations…with near perfect temperatures and some big events.

3 pink irises - Most of the irises were fading by May but there were three still in good condition in a flower bed at the side of our house which can’t be seen (by us or our neighbors) except by walking around our house. I saw them when I was mowing and cut them to bring indoors.

Bleu Monkey - The first thing we did in Hot Springs was to have lunch. We picked a great place – tasty food and a huge drink (that my daughter did not finish)…but what made it celebratory was the interaction with the other patrons!

Garvan Woodland Gardens – My daughter and I both celebrated our experience at Garvan Woodland Gardens (via golf cart and on foot). I’m sure we’ll go again…maybe experience it in every season over the next few years.

Whirlpool bath at Buckstaff Bathhouse in Hot Springs – The Buckstaff Bathhouse is a way to celebrate history and the great feel hot springs.

Large birdbath – I moved a large glass birdbath from Maryland but didn’t set it up last year because I didn’t think the old stand was stable enough in our environment. I bought a new stand at Branson’s Butterfly Palace last fall and celebrated how great it looks set up near our bird feeders…and that I’ve seen birds coming to get a drink.

Mowing the whole yard in one day – Usually I mow my yard over 2 days…so I celebrate when I can do it one. It helped that May was cool…I probably won’t attempt it when the temperatures are higher.

A new family member - One of my nieces had a baby girl….always a celebratory event.

New glasses - I celebrated new plastic frames (rather than wire rims with pads as the bridge) that feel better on my narrow nose bridge.

Salmon salad – Salad made with canned salmon and celery (and other veggies) with chipotle mayonnaise (or other spicy dressing) has become one of my favorite lunches. I celebrated rediscovering a staple (canned salmon) that my mother always had in her pantry.

Aurora from our deck – My husband and I both celebrated that we managed to see and photograph the aurora from the deck of our house! It was very special.

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.

Shasta Lake Filles Up Again - After consecutive wet winters in Northern California, Shasta Lake filled up for the second year in a row, in time for summer 2024. The healthy cache of water in back-to-back years was a welcome turnaround from drought conditions and low lake levels in 2019–2022.

The chemistry of hydrangea colors – This works for the Asian hydrangeas….not the North American natives (oak leaf and wood hydrangeas).

Are there long-terms health risks to using Botox? - Botox is the most common cosmetic procedure performed worldwide, with nearly three million injections estimated to take place each year. It works by blocking signals from the nerves that control the facial muscles. The muscles relax, and fine lines and wrinkles disappear. Very little is known about the long-term health effects of taking Botox, as most clinical trials only follow up on patients for six months or so. However, some studies have found that long-lasting cosmetic use of botulinum toxin can trigger permanent changes in facial expression, with persons no longer able to flex their facial muscles.

How a Small Herd of Romanian Bison Is Locking Away Thousands of Tons of Carbon - European bison were reintroduced to the Țarcu Mountains, at the southern end of the Carpathian range, in 2014. Now numbering 170, the bison are reshaping the mountain landscape in ways that are helping clean up emissions: the Țarcu grasslands are capturing roughly 10 times as much carbon as they were before bison were reintroduced.

Preserving The Thermal Springs And Bathhouses Of Hot Springs, Arkansas – This post from National Parks Traveler came out while my daughter and I were in Hot Springs. I saw it after I got home.

How Can You Stop a Disease-Carrying Mosquito? – Hawaiian honeycreepers are dying of avian malaria spread by mosquitos. Now there is a project that is releasing male mosquitoes (they don’t bite and don’t spread diseases, females are the ones that bite/feed on blood) that causes breeding to fail – thus causing the mosquito population to crash. Even if this is successful, there is more to do for the birds to thrive: forest restoration, keeping weeds out, eliminating invasive pigs, some captive breeding of the birds.

Blood pressure drugs more than double bone-fracture risk in nursing home patients - The medications tend to impair balance, particularly when patients first stand up and temporarily experience low blood pressure that deprives the brain of oxygen. Interactions with other drugs and low baseline balance in many nursing home patients compound the problem. A combination of less medication and better support could significantly reduce the problem.

Hurricanes, heatwaves and rising seas: The impacts of record ocean heat - Every day since late March 2023, global ocean surface temperatures have set new records for the hottest temperature ever recorded on that date….and the repercussions are already beginning.

Fewer Than 100 Cigar Orchids Found In Big Cypress National Preserve - A months long search for rare cigar orchids in Big Cypress National Preserve in Florida has turned up 85 of the plants the state of Florida considers endangered. No plant had produced any fruit in the 2021 and 2022 seasons.

Lead Pipes Make Up Nearly One Tenth of US Water Service Lines - Improvements to the 1991 Lead and Copper Rule proposed in late 2023 could finally require water systems to provide accurate information and enforce the replacement of lead pipes. However, a proposed exemption would give cities like Chicago an extension, letting them take multiple decades to replace infrastructure.

Then and Now – Heating

/

During the 1960s, the heating where I lived in Texas transitioned from electric wall heating to gas powered central heating. Both had to work harder because the windows of the houses were single paned and had little insulation. I remember that my grandparents’ houses were often colder in the winter than mine was. My paternal grandparents’ farmhouse had gas burning (probably propane) stoves in each room and my maternal grandparents’ house had gas burning (probably natural gas) floor furnaces; in those houses, the kitchen during meal prep time, was the warmest! Prior to the advent of thermostats, the controls on the heaters were tweaked manually.

My house now has two central heating furnaces (2 zones) – one natural gas and one electric. Within the next 5 years, we will be transition to electric powered heat pumps. The house has well-sealed doors and double pained windows….and was well insulated when it was built in 1999. It has two gas fireplaces which we haven’t used; the gas is turned off and we have sealed the vents with magnetic strips to stop the drafts in the winter. We have a ‘smart’ thermostat that we can program to change the temperature at different times during the day; since we are retired, that is usually letting it cool down a bit at night while we are sleeping.

In general, modern heating systems and houses, make it easier to feel warm in the winter. I wonder sometimes if that changes the early years of children’s lives. For example – a baby born in December would be learning to walk a year later. Prior to central heating, that would mean more clothes to get in the way during that process than a child born in July would have as they learned to walk. Did mothers of winter babies keep them close to their own bodies to make sure they were warm (i.e. did winter babies get held more in their very early lives)? Central heating might have made early childhood development more consistent because it took away much of the seasonal variation experience for babies!

Cat and Bird

/

There was a commotion in our hearth room…Sooty, our male cat, was at the window working with rapt attention at the glass. When I took a closer look, I realized there was a bird on the brick ledge on the other side of the window.

There was a commotion in our hearth room…Sooty, our male cat, was at the window working with rapt attention at the glass. When I took a closer look, I realized there was a bird on the brick ledge on the other side of the window.

It apparently was not intimidated by the actions of the cat since it stayed where it was for a few minutes to taunt the cat with its back. The bird had an excellent view of our bird feeders below. It might have been finishing up some seed it had retrieved previously.

We have three indoor cats – we don’t inflict non-native predators on our neighborhood. In our previous house, we had a screened in area of the deck that our cats enjoyed (outdoors but separated from the birds and other wildlife) but the windows seem to provide sufficient stimulation to our cats in this house.

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).

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.

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.
