Gleanings of the Week Ending December 25, 2021

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

New copper surface eliminates bacteria in just two minutes – One of the emerging technologies to fight bacteria (and viruses) without antibiotics. Copper is already being used in some applications, but this materials research developed a new structure of copper that is more effective and faster. The article didn’t comment about durability…but still very promising finding.

Home Battery Storage: The (Solar) Rich Get Richer – There is beginning to be more equity in solar panel installation….but storage is still a challenge at lower incomes. Some states have programs that may be the wave of the future and there are incentives in pending legislation. Hopefully a positive momentum will build over the next few years.

California Readies Launch of Largest Food Waste Recycling Program in the U.S. – Part of the county where I live in Maryland has curbside pickup of food waste for composting…but not the part where I live. I have a backyard compost bin…but many people do not so there is still considerable food waste going to the landfill.

10 Winter Birds to Spot During the Christmas Bird Count – Seen any of these in your area?

Why is snow white? – 3 videos…the last one with more ‘bonus’ explanations (such as why polar bears are white).

Top 25 birds of the week: Bird Pigment – This post was a bit confusing since it wasn’t explicit about which colors were from pigments ( as in the red of cardinals) and which were from light scattering caused by the physical structure of the feathers (for example, in blue jays). Read more about this non-pigment phenomenon particular for blue feathers here.

Winter is coming: Researchers uncover the surprising cause of the little ice age – New research shows that the little ice age in the early 1400s occurred when the Atlantic Meridional Overturning Circulation (AMOC) collapsed after a warming period which flushed Arctic ice into the north Atlantic, cooling it and reducing its saltiness. Could the AMOC collapse again with ice melting because of climate change? Existing climate models do not model the impacts of ice melt (making the north Atlantic cooler and less salty)!

From blood clots to infected neurons, how COVID threatens the brain – An overview of the research into how COVID-19 impacts the brain; there is still a lot more to be learned about this - probably one of the most devastating aspects of ‘long Covid’. It appears that the cognitive impact experienced by some COVID-19 survivors improves over time, but half the patients in one study were not back to normal after a year. It is a very sad prospect for individuals and for or society.

Watch This Giant Phantom Jellyfish With 33-Foot-Long Arms Float Through the Deep Ocean – The video is less than a minute…worth watching.

AAA Electric Vehicle Infographic — The Good & The Bad – My current car is a plug-in hybrid….the next one will most likely be an EV.

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.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory.  A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.

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

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

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

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

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

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

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

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

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

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

Trek to and in Druid Hill Park – Part II

On out way to Druid Hill Park through Baltimore, there were some trees that still had most of their leaves! All the ones around our house in the suburbs to the south of the city and the airport have lost all their leaves.

I wondered if it was the heat island effect of the city or the disruption of wind by building and walls; there are some city microclimates that cause the trees to keep their leaves a bit longer…very noticeable right now. I also noticed tents periodically on medians and places along the road with a little more space (see tent on the right under the trees in the picture below); is this the way the homeless people in Baltimore are surviving this winter?

There is graffiti on buildings…but there are also bits of city art on otherwise mundane buildings. I wondered if the height and lights are have kept the art intact in some places.

On the way home – the GPS routed us through downtown and I took pictures of the Bromo-seltzer Tower as we stopped at lights. It’s used for artists studios now….next to a fire station.

Overall – the birding walk was a tiny step back to ‘normal’ for us although both by husband and I are beginning to realize that we’ll probably never be quite like we were pre-pandemic. It’s not just the pandemic that has changed us; more on that thought is few days when I write my month COVID-19 pandemic post.

Gleanings of the Week Ending December 4, 2021

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Gleanings of the Week Ending November 6, 2021

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

19 Months in COVID-19 pandemic

19 months into the pandemic: the wave of infections from the delta variant is beginning to decline although the US is still experiencing more than 1,000 deaths per day; vaccine mandates are beginning to come into effect; schools are in-person, sometimes finding it challenging to keep outbreaks at bay; booster shots for high-risk Pfizer recipients were approved; it appears that approval for vaccination of children under 12 may be coming soon. So – it is still problematic but there are positive trends.

I am planning another road trip to Missouri and Texas later this month – expecting the trends to continue…the situation to improve along my route from Maryland. The KF-94 masks have protected me so far and I have a good supply for the trip. My concern has shifted away from contracting Covid-19 and toward the ‘what if’ concerns along the way. My road trips so far have been without incident, but I understand that if an accident occurred that required medical attention, the hospitals along my route might be overwhelmed with COVID patients…and that at least some people are so stressed by the ongoing situation that they become angry very quickly. So – I’ll be doing my usual careful driving and limiting my interactions…keeping the interactions I do have to cheerful greetings and checking in/out of the hotel.

I have enjoyed the volunteering I’ve done this month with 6th and 9th graders. They are old enough to wear their masks as well as I do! And they seemed pleased to be in school and having a field trip experience – more so that pre-pandemic years.

The idea of future pandemics is something I have been thinking about and how we have a new dimension of inequality: people that are vaccinated and people that are not. Most of the people dying from COVID-19 now are unvaccinated. And some percentage of people will recover from the initial infection but with long term health issues that will have health and economic impacts on the individuals and the country. Will that happen with other diseases that are prevented – or made milder – with vaccines: measles, chickenpox, mumps, shingles, pneumonia, whopping cough, tetanus, diphtheria, etc.? Some of those diseases might not kill people but there are sometimes long-term health issues that are expensive to treat and a continuing burden on our health care system. However good the system becomes to quickly produce effective vaccines – it won’t help as much as it should if people refuse the shot!

Even with that concern for the long term – I am thinking positive about the trends for this pandemic and hope that many more people will shift their attention to the present and looming impact of climate change….taking aggressive action to reduce and mitigate as fast as we can.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Schoolyard Volunteering

I volunteered for a pilot program about climate change concepts (carbon capture, water infiltration, urban heat island) for 6th graders held on their own school grounds. It was a positive learning experience for me…and the students as well. Howard County Conservancy held training beforehand so when the first one was held I was relatively well prepared….but the first time through is always tricky. My station was about carbon sequestration; the students measured the circumference of trees on their schoolyard to estimate the weight of carbon in the tree and the weight of CO2 absorbed by the tree. The students became more coordinated with the process as they measured more trees:  using a tape measure - 137 cm up from the ground and then measuring the circumference. Teams of 3 worked well (2 for the tape measure and one recording results). Then in the last part of the session we use a table to determine the carbon in and absorbed by the trees.

The second school was an earlier start…out of the house at 7 AM! It was also a cooler day (in the 60s and lower 70s) so more comfortable wearing a mask. The students are mostly too young to be vaccinated yet. I took a quick picture of my front flower bed and the morning sky before I left the house.

My first assignment was carbon sequestration for 2 student periods and then water infiltration for the next three periods of the day. Many of the trees we measured were about the same size – probably planted when the school was built. We learned that even the grassy areas of school yards don’t have good water infiltration – maybe because the mowers used on them are heavy enough to compact the soil! And even the water retention ponds (which were dry during the session) did not let the water soak in. The mulched areas under the trees were the only areas that showed good infiltration. Most of the rain that falls simply runs off rather than soaking in close to where it falls.

There was some break time between periods, and I observed some sparrows taking dust bathes in a bare spot near the edge of the school ground.

Overall – the students seemed to enjoy the program and collected data that they will use in their classrooms. I had my best experiences ever with this age group. Middle school is such a mix of student maturities…but the small groups made it relatively easy to engage all of them and keep them focused on collecting information about their school yard in a consistent, organized way. My lesson learned was that signing up for the full 5 periods is a bit overwhelming…probably won’t do that again!

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

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

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

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

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

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

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

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

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

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

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

Our Oak

Looking up into our oak that grows near our mailbox, it looks like fall is well underway. The flags left from the periodic cicada larvae this summer have dropped their leaves and the rest of the leaves are turning now too. I’ll need to do a round of mowing soon to keep the leaves from getting too thick on the grass. The Virginia Creeper has grown a lot this year…reaching higher into the tree than ever before. It’s a native and climbs with suckers rather than rootlets; it only damages the tree if it gets too heavy; right now, it is well within the range that the tree can handle.

That’s not to say that the tree is in great shape. Oak decline is happening all over the Mid-Atlantic. There are stressors are thought to weaken the trees: climate change, tree age, site conditions, history of disease. Our tree is probably 30-40 years old (the house is about 30 years old but the tree was planted as a sapling)…not very old for an oak. There is pavement on two sides of the tree (the street and our driveway) so soil compaction might be a problem. It has always had mulch and grass around its base and there are no exposed roots.

The stressors might have weakened our tree enough to make it vulnerable.  The way some of the leaves look is indicative of Bacterial Leaf Scorch. It will be years before the tree succumbs – finally starving (i.e. leaves turning brown and falling early…not continuing to produce food for the tree during the entire growing season). We’ll shore up its defenses by watering it during drought…keeping the fallen branches and debris picked up around its base. And eventually cutting the Virginia Creeper.

Annual Flu Vaccine

It’s that time of year again – time to get the annual flu vaccine. This year it was very easy for me; I went to my grocery store pharmacy just as I did last year… right after they opened. There was no line, and their system already had all my information. I filled out a form on a clip board, provided an electronic signature, and got the shot.

I refrained from buying myself a treat like a piece of cake or a soft drink -went to the nearby thrift store instead. I found 2 pairs of ‘like new’ leggings that are easy additions to my fall wardrobe!

I am still planning another road trip to Texas in October so getting the flu shot in September means it will be fully effective by then. I am hopeful that the high rate of infection and hospitalization along my route will be reduced by then – and that hospitals will not be as overwhelmed as they are right now…just in case some accident occurs along the way.  

On the same day I got the flu shot – we had a very hazy day in Maryland and it was attributed to the California wildfires. Signs of climate change are everywhere. For me – getting the flu shot is an action to avoid a health issue at a time when the pandemic and climate change are straining the resources of our country to deal with those disasters – making it even more challenging to take the strategic actions to reduce and mitigate the climate change going forward.

Gleanings of the Week Ending September 18, 2021

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

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

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

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

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

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

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

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

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

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

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