Gleanings of the Week Ending November 16, 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.

Drought Expands Across the U.S. – We are finally getting some rain…but we are in the ‘extreme drought’ area of southwestern Missouri; it is going to take a lot to get back to ‘normal.’ On October 29, abnormal dryness and drought affected over 78 percent of the American population—the highest percentage in the U.S. Drought Monitor’s 25-year-long record.

Cholera, Zika and West Nile: The deadly diseases that sweep in after hurricanes – Damage to infrastructure has been the big focus of reporting in the US, but diseases are ramping up.

• Florida health authorities released a warning in early October of a likely spike in Vibrio vulnificus infections, urging residents to avoid wading in floodwaters.  Vibrio vulnificus is a bacteria which can cause the breakdown of skin and soft tissue, sometimes leading to amputations.

• West Nile cases rose in Louisiana and Mississippi following Hurricane Katrina.

• Studies found that flooding in Louisiana following hurricanes Rita and Katrina led to an increase in the airborne fungi Penicillium and Aspergillus, which can cause allergies, respiratory infections and pneumonia.

• Research into the aftermath of hurricanes Maria, Irma and Michael, shows that a significant number of people in Florida developed new chronic health conditions such as asthma and allergies in the six months following the disasters.

Satellite Imagery Shows Breadth of Flooding in Spain - Valencia saw a year’s worth of rainfall in just eight hours, with floods destroying buildings, disrupting trains, and leaving more than 100,000 homes without power.

What animal societies can teach us about aging - Humans are not the only animals to change our social behavior as we age. Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off.

The world’s oldest tree? Genetic analysis traces evolution of iconic Pando forest - By sequencing hundreds of samples from the tree, researchers confirmed that Pando, a quaking aspen tree (Populus tremuloides) in Utah, is between 16,000 and 80,000 years old. Pando consists of some 47,000 stems that cover an area of 42.6 hectares in Utah’s Fishlake National Forest. Because of the way the plant reproduces, this collection of aspens is technically all one tree, supported by a single, vast root system. Pando is triploid, meaning that its cells contain three copies of each chromosome, rather than two. As a result, Pando cannot reproduce sexually and mix its DNA with that of other trees, and instead creates clones of itself.

Have we found all the major Maya cities? Not even close – Using lidar to survey 50 square miles revealed evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

Stunning Shortlisted Photos From the 2024 Close-Up Photographer of the Year Contest – My favorite was “Chicory” for the color…and that I knew what it was!

Low-level lead poisoning is still pervasive in the US and globally - Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children. Factors such as menopause and hyperthyroidism release lead sequestered in the skeleton, which causes a spike in blood lead concentrations. The solution to protecting people from lead poisoning is to identify and eliminate environmental sources of lead: eliminating lead acid batteries, replacing lead service lines, banning leaded aviation fuel, reducing lead in foods, abating lead paint in older housing, and further reducing lead-contaminated soil and other legacy sources.

Ghost Forests Creep Into North Carolina - Large swaths of cypress and pine forests along the southeast Atlantic coast have died, shed their bark, and become pale, leafless snags that line the waterways like gravestones. In the period before winds topple the snags over and shrubs cover them up, researchers call the eerie ecosystems “ghost forests.” One place that is it happening is Alligator River National Wildlife Refuge…and I realized I have been there! We visited in April of 2015. It was the first place I saw river otters and two vultures (different species) sharing a meal. There probably were bald cypress dying in 2015, but it is even more evident now.

Trees cool better than reflective roofs in vulnerable Houston neighborhoods - Heat islands occur in cities where structures such as buildings and roads absorb the sun's heat more than natural landscapes such as trees and grass. The researchers considered three different heat island mitigation strategies: painting roofs white to increase solar reflectance; planting vegetation on roofs to increase evaporation through the plants; and planting more trees, which increases evaporation and provides shade.

Antarctic 'greening' at dramatic rate - Vegetation cover across the Antarctic Peninsula has increased more than tenfold over the last four decades… fundamental changes to the biology and landscape of this iconic and vulnerable region.

Is cleaning with baking soda better for the environment? – Maybe not…and it might not be very good at some types of cleaning either.

Meet Milagra, a Rare Condor Rescued as an Egg and Newly Released Back into the Wild – A success at Arizona’s Vermilion Cliffs National Monument.

Landslides, Thousands Of Downed Trees, Undercut Roads Along Blue Ridge Parkway – Lots of repairs for the National Park Service after Hurricane Helene. Some damage is severe enough (i.e. more than just clearing mudslides and debris) that it will take time to repair. The fall foliage will come and go.

In Search of Microbes That Weave Colors into Moroccan Carpets - A scientist’s quest for microbes that produce purple pigments led to the vibrant world of natural dyes for women in the Atlas Mountain region of Morocco creating sought after traditional woven carpets…it’s a great intersection of biology and traditional artistry! The findings are compiled into a 48-page open-source guidebook, also translated into English, which described their project, introduced microbial dyeing, and catalogued recipes for plant dyes.

Dementia diagnostic markers change with time of day - Biomarker levels (p-tau217) were at their lowest in the morning when participants woke and highest in the evening.

Great Lakes Water Quality Project Seeks to Restore Coastal Vegetation - Returning certain croplands to perennial vegetation to reduce runoff and limit erosion.

'A warmer, sicker world': Mosquitoes carrying deadly diseases are on an unstoppable march across the US - West Nile virus, Eastern equine encephalitis (EEE), malaria and dengue…The mosquitoes that carry these diseases are thriving in a warming world.

Extinct Volcanoes Could Be Source of Key Metals Needed for Clean Tech - Rare-earths lurking under extinct volcanoes may be easier to extract. The iron-rich magma that formed some extinct volcanoes would be up to 100 times more efficient at concentrating rare-earths than the magma found in active volcanoes today. By one estimate, demand for rare-earths is set to grow fivefold by the end of this decade so finding them closer to home could contribute to more rapid conversion to clean technologies.

See Newly Discovered Nazca Drawings That Depict Llamas, Human Sacrifices and More - With the help of artificial intelligence, researchers have found hundreds of ancient artworks carved into the pebbled ground of Peru’s Nazca Desert in 6 months compared to 430 found between 1927 up to before the use of AI.

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 an asteroid impact would transform the food we eat – Thought provoking…and scary. Right now, I am beginning to wonder how the level of drought in the US is going to change the food we eat…or will we eat the same way but pay much higher prices.

A Field Guide to Unexpected, Out-of-Place Wildlife – Why wildlife shows up in the ‘wrong’ place… I had read about the shifting range of armadillos last spring (was reminded of it by the reference to the Virginia opossum in this post).

State Of the Birds Report: More Than Half of U.S. Bird Species Are Declining – Sad….another indicator that the Earth is changing.

Economic losses from hurricanes become too big to be offset by the US if warming continues – I’ve been wondering about this since Hurricane Harvey and finally there is some analysis of the data…but, so far, it does not seem to be changing the way we deal with the aftermath of these catastrophic storms. The dominate idea still seems to be ‘rebuild.’

Life expectancy improves in some countries after big drops in 2020 – but US and others see further falls  - The life expectancy at birth in the US was 79.8 in 2019 and was down to 77.4 in 2021. It might take a few years until the impact of COVID-19 on life expectancy is fully understood. It seems to me that there are other cultural changes that happened concurrent with the COVID-19 pandemic that could impact life expectancy in the US into the future: reduced vaccination rates, reduced trust in medical professionals, increased belief in whatever is said on social media and conspiracy theories, increased stress/mental health challenges, etc.

The Clean Water Act at 50: Big Successes, More to Be Done – The Act was passed the year I graduated from high school. I had done a project about algae as pollution indicator in the streams around Dallas, Texas in the fall before so I was aware of water pollution issues of the time. It is frustrating that there is still so much to be done….

New model of Alzheimer’s as an autoimmune disease – A new perspective….maybe leading to new therapies in the future.

Ancient Maya Cities Were Polluted with High Levels of Mercury – The Maya coated surfaces (walls and floors and bodies) with cinnabar…and the mercury from that leached into the water supply and soils. Chronic mercury poisoning causes tremors, weakened vision and hearing, and paralysis! The contamination at some sites is high enough that archaeologists need to use mitigation techniques and protective gear.

Young kids avoid one learning trap that often snares adults – Young kids are not as good at focused attention as adults which means they notice new things happening away from a ‘focus area’ more quickly…..but focused attention can also mean learned inattention in adults which might not be the best strategy in all situations.

After Three Summers, Man Finally Gets Photos of Hummingbird with Rainbow Wings – Beautiful pictures. They prompted me to look up why hummingbird feathers can show the colors of the rainbow. I found a Science Daily post from back in 2020 that offers an explanation.

Most Memorable of 2020

Looking back on 2020 – there is so much that was different than prior years. There has not been a year of my life with so many significant types of upheaval: COVID-19 pandemic, environmental disasters (fires, hurricanes), racial strife, and strident politics. Today I am writing about the way this year was different for me as an individual with those upheavals as the broader situation.

Early year travel…then no travel. In prior years, I enjoyed travel throughout the year – being away from home a week or less at a time and daytrips. My original plan for 2020 was to spend a week of each month in Texas with my family. The early part of the year started out on that plan – a visit with family and a birding festival in Laredo, TX in late January and early February. We talked with an HHS person in the San Antonio airport; she was headed to the base where some of the first cruise ship passengers were arriving for their quarantine period. Once we got home, we hoped the virus was going to be limited to the few groups from cruise ships that were talked about in the news….and we started paying more attention. It quickly became apparent that telephone calls and Zoom meetings would have to take the place of the trips to Texas. We did some 2-3 hour outings for some outdoor time in the fall; we wore masks even outdoors and distanced from others; now that the infection rate is higher in our area and it’s often too cold to be outdoors for very long, we are not attempting more than walks around our neighborhood.

The Pandemic. By March, we had an inkling that COVID-19 was not going way and that there was more around in the community that anticipated. The grocery stories started having shortages of toilet paper and disinfecting products and hand sanitizer. Fortunately, we had an adequate supply of those to last until the stores had them again (although maybe not the brands we bought previously – what happened to Formula 409?). I went to an ‘over 65’ shopping hour at a local grocery in March and it was crowded enough that it scarred me into switching to grocery delivery for 2 months. I tried to keep 2-3 weeks of food in the house at all times. We bought over the counter medications that might help symptoms if we got sick. By the summer I was comfortable going to the grocery store again – masked and going at 6:30 AM every other week and, now, extending to every three weeks. We do curbside pickup at some local stores and restaurants. My husband has virtual and in-person appointments with his doctors, but we both delayed routine optometrist and dental checkups that started to be due; those appointments and my annual physical can wait until after we are vaccinated.

Cultural, environmental, and political drama. The pandemic would have made this a challenging year but with the cultural, environmental, and political drama happening as well – the news was overwhelmingly bad…traumatically bad. The trauma of seeing the murder of George Floyd by a policeman brought to the consciousness of the country that racial equality before the law is not something the US has achieved…and the varied response to the event showed us more about how deep the challenge runs in our culture…and highlighted other manifestations of inequality in our country. Because of our ‘stay at home’ strategy during the pandemic, we didn’t witness any unrest – but the news prompted some donations and solidified our votes in November. There were environmental disasters – fires in the west, hurricanes on the Gulf Coast; neither impacted us directly in Maryland, but it was very easy to be traumatized imaging how awful it must be for people trying to take precautions to not get COVID-19 but having to evacuate and then returning to find their home gone or damaged. The political drama – much of it seemingly intentionally done to sustain a level of chaos – continued through the end of the year; I became more angry as time went on that the leadership of the country – in a year of extreme national stress – seemed to be acting to increase the trauma.

Virtual birding festivals and conferences. I saved some positive things to write about for the last of this post….we all need something positive to sustain ourselves. My husband and I both enjoyed virtual birding festivals and conferences in 2020. They added variety to our weeks; we appreciated the work of the teams that made the transition to virtual because they took us away from our immediate environment (not quite as good as travel but the best we were going to do during the pandemic). We hope to be back to some in-person events in the second half of 2021. The ones we did virtually in 2020 were:

• May – Cape May Spring Festival (New Jersey)

• June – Mid-Atlantic Climate Change Education Conference

• July – Get into your sanctuary (NOAA)

• July and August – Sara Via Climate and Sustainability Webinars

• September – Yampa Valley Crane Festival (Colorado)

• September – Puget Sound Bird Fest (Washington)

• October – Cape May Fall Festival (New Jersey)

• October – Hawaii Island Festival of Birds

• November – Crane Fiesta (New Mexico)

• November – Patuxent River Conference Reflections

• December – Maryland Water Monitoring Conference

• December - AGU

At home. I spent more time at home this year than every before in my life (that I can remember…maybe I spent more time at home from birth to 4 years old). It’s been different but not hard. The house is well situated with forest to the back and a 30-year-old neighborhood street to the front with lots of trees as old as the houses; the views from the windows are all good – and there is wild life (birds (including an occasional wild turkey!), squirrels, deer, chipmunks, and racoons (seen only on the bird feeder cam in the wee hours of the morning)). Individuals and couples take walks…the neighborhood does not feel vacant or isolated. Inside - my husband and I have plenty of room to enjoy our individual projects/activities then be together for meals and shared activities…settling into a comfortable way of living in the house together and probably becoming more synchronized emotionally than we have since early in our marriage – simply because we are around each other more.

Conscious efforts to sustain healthy mental and physical health. As we’ve gotten older, we have become more intentional about our lifestyle – making sure we get enough exercise…eat healthy…assess our feeling and act to keep them positive. During this year – we have increased our focus. I had time to process the bounty of the CSA season (June-October) and am just now beginning to see that we have space in the freezer again. We eat well but keep our portion sizes reasonable; we haven’t gained weight…maybe we’ve lost a few pounds. We both try to get some outdoor time as frequently as we can – walks, yard work, reading on the deck, photography (stars/planets, sun, plants, animals, and snowflakes) etc. It was easier before it got cold. More of our exercise has shifted indoors at this point. We do things to brighten our mood – flowers, purchases to use for projects (mounted insects, clickers and magnifiers for cell phone photography), special pens, special food – things to make each day a little different.

Overall – at the end of 2020, I am feeling optimistic about 2021 and pleased that my husband and I have responded with resilience to the changes in our lives during the past year. We had ups and downs but on the whole managed to sustain ourselves and to enjoy parts of every day (for me it was easier when the television was off, and I wasn’t reading my news feeds).

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.

New report deepens understanding of wind-wildlife interactions -- ScienceDaily – This article overviews the report. The 24 page report is available here. The amount of collaboration between the industry, government, conservation, academic and scientific organizations is significant and ongoing.

Marsh-Billings-Rockefeller National Historical Park Celebrates Forests – Maybe I’ll go to Vermont for this festival next September – if it’s an annual event.

These surreal jarred fish tell an urgent story of extinction – The Royal D. Suttkus Fish Collection – nearly 8 million preserved fish…a window into how 20th century development changed the Southeastern US fish….a record of that destruction.

No bones about it, this protein slows down fracture-healing -- ScienceDaily - Abundance of ApoE may explain why older people have trouble healing broken bones. Turning off ApoE completely causes fat to be deposited in arteries (a cardiovascular problem) so treatment options may involve lowering ApoE for short periods of time.

O Canada! We Like Your Food Guide – Food guides from Canada (and some other countries) … some differences from the US. Canada merges ‘dairy’ in with protein foods rather than featuring it as an independent group.

Scientists Are Getting Better at Predicting Hurricane Intensity – A new algorithm has been developed to include the complicated physical mechanisms of tropical cyclone dynamics and the way they interact with upper-ocean and atmospheric circulation. It may reduce the error of tropical cyclone prediction within a 24-hour period by 16%. Every little bit of improvement in prediction means better preparations when an intense storm is approaching.

Artworks of the Dark Zone – From caves in Tennessee and Alabama. Artwork incised in mud and inscriptions. A slideshow.

How Penn State is Cutting Greenhouse Emissions in Half – and Saving Money – Kudos to Penn State. I wonder how many other universities are doing similar things.

Empty Meditative Landscapes Visualize the Tranquil Beauty of Silence – A visual treat

Ed Hawkins “Climate Stripes” May be the Most Important Science Image so Far in This Century – Effective visualization of lots of data…becomes information. The next step is action.

Earth Matters - New Tools to Boost Access to NASA Earth Science Data – How NASA is using big data strategies to streamline processing time to get the information from satellites into usable form.

Trend of the Month… asocially| What's Next: Top Trends – Richard Watson noticing that some people prefer to be left along to look at their devices.

Image of The Day: Open-and-Shut Case | The Scientist Magazine® - They used box turtles in this research….a turtle we see here in Maryland relatively often.

Top 25 Wild Bird Photographs of the Week: Migratory Birds 2 – National Geographic Blog – Tis the season for bird migration!

BBC - Future - Should everyone be taking vitamin D? – It’s not clear cut. In the winter we probably don’t get enough Vitamin D from diet/sunlight…but the impact of that shortage is not obvious in many people. There are some trials that are ongoing that may provide some answers.

Why the Current Hurricane Rating System Needs to Be Scrapped - Yale E360 – Hurricanes are rated based on wind-spead….but storm surge and flooding for rain (coastal and inland) also causes damage. Hurricane Florence is an example of a Category 1 storm causing tremendous damage even though it wasn’t a ‘major’ hurricane.

Detailed maps of urban heat island effects in Washington, DC, and Baltimore | NOAA Climate.gov – Close to home for me since we live between Washington DC and Baltimore (not on either of the two maps).

Well-Preserved Murals Discovered in Pompeii - Archaeology Magazine – Finding new things in a site that has been studied for many years.

Surprising places where germs lurk in bathrooms | Berkeley Wellness – Hmmm…maybe we should add some tasks to cleaning the bathroom.

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.

Two places to look at bird images: Stunning Winners of the 2017 Bird Photographer of the Year Contest and Top 25 Wild Bird Photographs of the Week #104 – I can’t resist. Birds are such interesting subjects for photography….and challenging enough to engage photographers the world over.

This is how Pittsburgh is taking climate action – Now that my son-in-law is in Pittsburgh for his post doc, I am learning more about the city. It’s moving way beyond its heavy industry history. The Phipps Conservatory was one of the places mentioned in the article as a place that generates all its own energy and treats/reuses all water captured on site! We visited the place last March (see blog post here).

‘Rubber material’ discovered that could lead to scratch-proof paint for car – Wonderful if it can be made available at reasonable cost.

Silicon Valley Courts Brand-Name Teachers, Raising Ethics Issues – School needs to prepare students with skills they will need as they get older….so it can’t stay be anchored in the past. The challenge is to not set a new high-tech anchor that is expensive and potentially a dead end or not very effective. The pace of change that adults and children have in their lives is ramped up; perhaps a life skill we all need it how to cope with that pace of change without being overwhelmed.

How self-driving cars will change the American road trip – I’ve been thinking about this recently and was disappointed in this article in that it hypothesized the cars stopping every 180-200 miles. If I was on a road trip and only stopped every 3 hours or so….I’d be very stiff by the end of the day. Does the author think that the interior of self-driving cars will be different enough that people can somehow move around a bit more rather than just sitting relatively still? What about children and older people that can’t ‘hold it’ for 3 hours? If the cars or autonomous enough – will we be more likely to be traveling through the night and the car just stopping when it needs to for charging with us sleeping through everything?

Exploring Europeana in Czech, Irish, Slovak and Slovenian – One part of my family is Czech so this post caught my attention. I don’t speak the language but I’m interested in the art my ancestors might have seen before they left in the late 1800s.

West Coast Monarch Butterflies Flutter Toward Extinction – The numbers of west coast monarchs have declined by 97% since 1981. Very sad. Monarchs are declining all over the US not just the east coast ones that migrate to Mexico.

We could lessen the toll of hurricanes – but we don’t – A timely article after Harvey and Irma – so much destruction…of places and people’s lives.

New Guide: Energy Efficiency at Home - ASLA has created a new guide to increasing energy efficiency through sustainable residential landscape architecture, which contains research, projects, and resources.
