Gleanings of the Week Ending November 21, 2020

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.

Photography In The National Parks: The Redwood Forests Are Made For Vertical Shots – Botany (redwoods), photography (including two short videos), natural places…a great way to start the day or boost my mood any time.

Tarantulas: Color, Cancer and Cramps – I remember a tarantula on the sliding glass door of our house in Wichita Falls, TX when I was in my early teens…at eye level. Fortunately, it was on the outside and I was inside. It was about the side of the palm of my hand. This article talks about research on tarantulas; they are probably more interesting than scary!

The cheap pen that changed writing forever - BBC Future – A little history for the week. The ballpoint pen was unveiled on October 29, 1945 in the US. However – the first patent for a ballpoint pen was back in 1888. Laszlo Biro developed a practical ball point pen by perfecting the ink (different than ink used in fountain pens) and got a patent in 1938 in Britain but World War II came along, and he fled to Argentina. His pen was released in Argentina in 1943, but the pen was little-known outside of South America. Find out more from the article.

Biophilic Cities For An Urban Century – During the pandemic, I have appreciated where I live for its proximity to nature; I live at the edge of a forest and the 30 year old development has larger trees in the yards too. Turning our cities from gray to green would be different but there are reasons to make the choice to do it. The authors consider urban economics, environmental health, and ecology…and propose that going forward that we should actively design for biophilic cities. If cities were more like the first picture in this article (and all those cars below were electric) – they would be much more pleasant places to live!

Top 25 birds of the week: Wild Birds! – Can’t resist….I always enjoy the collection of bird photos every week…so include it in the gleanings list.

Slideshow: How Ecologists Study the World’s Apex Predators – Projects from around the world studying the impact of predators…using a variety of techniques.

New solar panel design could lead to wider use of renewable energy: Designing solar panels in checkerboard lines increases their ability to absorb light by 125%, a new study says -- ScienceDaily and Solar Panels + Agriculture: You Ain’t Seen Nothing Yet – Two articles about solar panels….we’ve seen more of them in the past few years…there are a lot of indicators that it’s only the beginning of the upward trend gaining momentum.

The Craters on Earth – They mapped 200 sites – high resolution topographic maps and satellite images…geological descriptions and photographs…details of each impact event. I followed the links and found that publication is available for pre-order here; the page provides the table of contents and additional sample images.

How Cowbirds raise their young, without raising their young – We had a group of cowbirds at our feeder one day this week. They seemed to be moving through rather than staying. There were some last spring as well, but I didn’t notice any cowbird chicks coming to the feeder like I have in previous years.

Plastic-eating enzyme 'cocktail' heralds new hope for plastic waste -- ScienceDaily – It appears that we are getting closer to a cost effective was to endlessly recycle plastic – which would dramatically reduce the need to produce plastic from fossil fuels. It’s also a good example of the benefit of collaborative research – international…multiple specialties…sophisticated (and rare) equipment.

Unique Activities for Yesterday:

Bosque del Apache Sandhill Cranes. We are enjoying the Bosque del Apache Crane Fiesta. It started out with a live video of the morning fly-out of the cranes. The recording is now available on the Facebook page of the refuge….remember to turn on your speakers to listen to the birds and enjoy the sunrise (it starts out before sunrise and runs for more than an hour)!

We’ve been to the area twice in November for the Festival of the Cranes and we always enjoy photographing the cranes (and snow geese) each morning. I simulated it by taking screen snaps as I watched the live video. Enjoy my little slideshow…but watch the video from the refuge’s Facebook to get the full effect!

Gleanings of the Week Ending November 14, 2020

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.

Mapping out rest stops for migrating birds: New metric can help determine when birds fly over a site or stop to refuel or rest -- ScienceDaily – Stopover-to-passage ratio during migration research involves analysis of weather radar data collected since the 1990s…teasing out bird movement from precipitation! Results so far have included some surprises (and there are probably more to come as more of the historical data is processed and the processing becomes more and more sophisticated).

This Crocodile Dad Gives Over 100 of His Kids a Lift – A large species (gharial) with a narrow snout…in India.

Top 25 birds of the week: November 2020 – Birds from around the world….so much beauty in the natural world to see…and try to protect.

Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report and US Energy Dept. Aims For Affordable Solar Power – Two posts about solar power. The first article shows the growth since 2012. In states where there wasn’t much growth, I wondered if the utilities in the state or the state government posed barriers to solar power. It seems like the whole country  should be in the mode of getting out of the way or encouraging renewal energy. The second article was about community solar programs from DOE with a mission to ‘bring affordable solar power to every household in the US by 2025’ – a worthy goal but is there enough money in the pipe to do it? This is not a technical problem as much as ‘are we ready to just do it.’

Lullabies in any language relax babies -- ScienceDaily and Baby Bottles Can Shed Millions of Microplastic Particles: Study | The Scientist Magazine® - I’ve been thinking recently about how much things have changed since my daughter was a baby over 30 years ago. I had a lullaby tape (in English) that I played for her in the evenings (although when she got old enough to choose – she wanted soundtracks from Disney movies as often as the lullabies). Now – we’d have digital music playing (rathe than cassette tapes) and maybe there would be lullabies in different languages too. The second article is about some worrisome research and I hope that pediatricians are keeping up and advising parents on best approaches.

When Domestic Birds Go Wild – Chickens, turkeys, ducks, swans, guinea fowl, peacocks, ornamental pheasants, doves and pigeons, emus, and parrots.

Picturing Earth: Astronaut Photography In Focus – A video – just under 70 minutes….with good imagery and discussion.

The return of Europe’s largest beasts - BBC Future – Bison, wolves, and elk…will the agricultural sector of Europe learn to cope with the big herbivores…and a predator?

As Waters Warm, Ocean Heatwaves Are Growing More Severe - Yale E360 – It’s easier for us to notice the heatwaves on land…but the ocean is taking the bulk of the increased heat on the planet and research on marine heatwaves is just beginning. The precise definition of the phenomenon was only proposed in 2016.  

See the World in Detail Thanks to the Close Up Photographer of the Year – Ending the gleanings list this week with some eye candy….enjoy the visual treat.

9th Anniversary for my Blog

I started my blog on November 11th, 2011.

The very first post was about making Pumpkin Gingerbread Muffins. Maybe I’ll make the recipe again this year. Brookside Gardens and Longwood Gardens had wonderful displays for fall gourds and squashes that year. I was doing some photography then, but a good portion of the blog posts weren’t illustrated. Now the majority of posts have a illustrations and sometimes the topic is the illustrations themselves.

Travel has continued to be a blog topic all along…which has made this year different from all the preceding ones; it’s been a year dominated by being ‘at home.’ The most frequent destinations in previous years were where my family lives – the Dallas, TX area for my sisters and parents….and then a sequence of places for my daughter: Tucson, AZ for grad school, Pittsburgh and State College, PA for post doc, and Springfield, MO for faculty position. During some of the years I travelled with my sister…to South Carolina, Tennessee, and Rhode Island. My husband and I discovered Birding Festivals as a travel focus beginning in 2016 with Bosque Del Apache’s Festival of the Cranes. As soon as the pandemic wanes (probably with the wide availability of a vaccine), we’ll be traveling again and the blog will pick up that thread again.

Books have also been a blog topic all along. The trend has been toward eBooks which are now about all I read. The botanical eBooks list has grown to over 2,000 volumes at this point and is still growing! I’ve become more interested in images of all kinds – photographs, paintings, etching, sketches – and I appreciate viewing them online rather than in a museum or physical book; I like to take my time, sometimes enlarge a particular portion of the image, view them on just about any device and almost anywhere!

I have made pattern-like doodles for as long as I can remember, and they have been part of the blog posts for most of the 9 years. Now they follow the Zentangle tile process – most of the time. I’ve diverged in several ways and that will change over time. At present I am making tiles in black ink with the idea of coloring them….adding white highlights as the last step. I am not using a pencil at all (for strings or for shading).

Gleanings have also been in the blog for most of the 9 years. My feeds have changed slightly but are still skewed toward science related topics. One trend I noticed is that the solutions to address climate change have matured over the past 9 years. There are a lot of effective technologies available to choose from (see Project Drawdown) – which add some hope to an otherwise dystopian future for the Earth and humanity.

My outdoor volunteering ramped up over the 9 years and I enjoyed writing about it…then that aspect of life came crashing down with the pandemic. I am hopeful about it starting again sometime in 2021. Giving back to the community, interacting with schools on field trips and people visiting Brookside’s butterfly exhibit is a joy I’ve missed in 2020.

I’ve been in my same home office for the entire 9 years and the view through the window is always fabulous – out to the bird feeder/bath on our deck and back into the forest. The view is inspiring and pictures I take through the window often make it into blog posts. Probably my favorite sequence is of bluebirds bathing from back in February 2018. I collected a sequence of ‘through the window’ pictures from 2012 through 2019 for the slideshow below. The feeder was added in 2015 which was a big attraction for November birds. I also noticed that the zoom on my cameras improved over the time period!

The very first post about little celebrations was back in August 2012 and then I started the listing of 10 each month in September 2012. Noting the joys of life is one of the ways I keep myself optimistic…which I’ve needed more than usual in 2020. Stream through the ‘celebration’ posts via this link.

The blog continues on….documenting my post-career journey. These pandemic and political upheaval months of 2020 have probably been the most unusual – and anxious - of my life; I am looking forward to the new year and documenting the events that unfold – finding celebrations.

Gleanings of the Week Ending November 7, 2020

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.

Taking the measure of sea level rise - ocean altimetry, land motion, ice height, gravimetry – NASA missions that measure some aspect of sea level rise…there is a lot to work to measure and analyze – to better understand that is happening.

Health Care Facilities Maintain Indoor Air Quality Through Smoke and Wildfires | U.S. Climate Resilience Toolkit – Some of the HEPA filters purchased for the pandemic were available and were used to keep hospitals operational in areas where the outside air was smokey. Are we going to need this type of filters in our homes as well – for air quality more than the pandemic?

Top 25 birds of the week: Seabirds – Beautiful birds…from all around the world.

From Palmyra to the Pacific: Realigning a Rainforest – Cool Green Science – An atoll 1000 miles southeast of Hawaii…marred by human intervention…now owned by The Nature Conservancy…inspiring the creation of the Pacific Remote Islands Marine National Monument in 2008. Restoration is ongoing to maximize Palmyra’s resilience to climate change: eradicating black rats, realigning native rainforest (not restoring because what was there originally is unknown), and reintroducing native bird species.

Red maples doing better in the city -- ScienceDaily – Hurray for red maples. The study was done in Philadelphia which is a couple of hours from where I live….and I have a health red maple in my back yard!

Deformed Beaks: What We Know About An Alarming Bird Disease  - Avian Keratin Disorder (AKD) which might be caused by a poecivirus. The birds in the article are from Alaska but some are species we have hear in Maryland too. Hopefully, this is not a disease that will become widespread.

Top US States for Percentage of Electricity from Solar – Even states that aren’t normally viewed as ‘high sun’ are near the top of the list! This chart will probably change a lot over the next few years as more and more utility companies and individuals transition to renewables. Government can help but it is quickly becoming the more cost-effective path forward…market forces will drive the transition.

Scientists Discover New Human Salivary Glands | The Scientist Magazine® - Tubarial glands…what a surprise that they haven’t been discovered previously!

Floating gardens: More than just a pretty place -- ScienceDaily – It is a small experiment…but there was measurable nitrate reduction by the garden….maybe it is something that could be scaled to reduce accumulation of nitrate (from agricultural and yard runoff) that causes algal blooms.

Largest Arctic Expedition Ever Comes to a Close | Smart News | Smithsonian Magazine – The Polarstern, a German research vessel, is back in port after spending a year drifting with the ice floe across the Arctic. It will take 2 years to fully process all the data collected but the initial assessment of the Arctic environment is summarized as grim: ice gone in places it should be meters thick.

Gleanings of the Week Ending October 31, 2020

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.

What’s That Cloud? Your Guide to Cloudspotting – A little tutorial. Maybe a prompt to do some cloud photography too.

This white paint keeps surfaces cooler than surroundings, even under direct sunlight -- ScienceDaily – I remember being at White Sands National Park on a hot day and walking on the sand barefoot (i.e. the sand was not hot!). Hopefully the architectural norms will begin to shift toward white roofs and then durable paints/shingles will be readily available to make it affordable. The heat islands of cities would be reduced…which could be helpful now and an increasing benefit as climate change continues.

Google Maps Gets More Electric-Car Friendly – Android Auto (not the phone app) adding features.

Top 25 birds of the week: Land-birds - Wild Bird Revolution – Enjoy bird images!

NASA's OSIRIS-REx spacecraft successfully touches asteroid -- ScienceDaily – We went down to Florida for the launch back in 2016 so I try to at least scan articles with updates. The sample is now safely stored away and will be heading back to Earth…arriving in 2023.

Why older people are harder to vaccinate - BBC Future – What vaccines can do…what they might not do. For example – did you know that the flu vaccine reduces disease but does not do much to reduce transmission because a vaccinated person can still shed virus particles?

Black Witch Moths: A Night-Time Trick or Treat – Because it’s Halloween….it will be a very quiet one this year with the regular form of trick-or-treating called off in our area.

The rats evicted from paradise - BBC Future – A positive result for humans correcting a problem we caused….only able to succeed because of the resilience of nature (and because we corrected before it was too late for recovery).

Flowers Are Changing Color in Response to Climate Change | Smart News | Smithsonian Magazine – Adjusting UV pigmentation to protect themselves (rising temperatures/thinning ozone)…maybe confusing pollinators.

Nature Nerd Trivia: Wild Canids – Dog relatives from around the world.

Unique Activities for Yesterday:

Firsts for the season at our deck. We saw our first Dark-eye Junco for the season. A small flock has spent the winter in our area – frequently visiting our feeder – for many years. We think they go to the Appalachians/Alleghenies for the rest of the year rather than the far north.

I finally managed to get a picture of a Red-breasted Nuthatch enjoying the seed spilled under our feeder. There were other times recently that I thought I saw one but was never fast enough with my camera.

Hawai’i Island Festival of Birds Swag pack arrived. It took more than 10 days for the small envelope to get from Hawai’i to Maryland. I don’t know for sure how long it took because there was no postmark. I will use the field notebook (upper left, a nice fit for one of my photo vest pockets) and the magnet (lower right) is already on our refrigerator to remind us of the virtual festival…and we’ll sign up to go to the festival when it is held ‘in person’!

Gleanings of the Week Ending October 23, 2020

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.

Painless paper patch test for glucose levels uses microneedles -- ScienceDaily – A technology (microneedles) looking for a problem to solve (prediabetic testing). So far - it’s just a lab exercise but they were readying for human trials. They didn’t explain why it was focused on pre-diabetic testing and not for diabetics.

Top 25 birds of the week: Non-migratory – Beautiful birds…always a visual treat.

These are some of America’s most beautiful urban parks – The one in Greenville, SC looked very non-urban!

Food mechanics recipe to serve up healthy food that lasts -- ScienceDaily – Basic research in plant-tissue response to heat and drought…preserving food through drying.

Doing Something About Global Warming Is Cheaper Than Doing Nothing – I selected a series of gleaning for this week that are focused on various aspects of climate change – with a mix of perspectives. This is the first one. For the pure capitalists…this one makes the argument for action in their terms. This first article came out back in September…so it is a little dated…but still makes some good points.

The daring plan to save the Arctic ice with glass - BBC Future – Do we want to consider Geoengineering?

40% of O'ahu, Hawai'i beaches could be lost by mid-century -- ScienceDaily – Sea level rise…and our response to it.

6 Graphics Explain The Climate Feedback Loop Fueling US Fires – Some good graphics about the fires on the west coast of the US. In recent days, fires in Colorado have been added to the news. At a time when forests sequestration of carbon is important for the health of the planet….the fires are reversing that benefit.

Natural Debate: Do Forests Grow Better With Our Help or Without? - Yale E360 – Hurray for natural regeneration – unless the land is too degraded for that to be possible…then our help is needed.

The Best Places for Solar Power If You Want to Clean The US Grid – Where investing in solar power would do the most toward reducing grid emissions…by state.

Unique Activities for Yesterday:

A busy morning. The only extra activity I’d planned yesterday morning was to get my car washed since the dirt road into the CSA is history for the year. The car is cleaner (at least on the outside) than it has been for months! The weather was so great when I got back that I swept the leaves from the driveway, street gutter, and deck onto the yard so that the mower would mulch them when my husband mowed later in the day. When I got back inside – I noticed my husband had called from the vet parking lot saying his battery was too low to start his car (and the vet had resolved the cat’s bleeding claw issue)….so I was off to help that car situation. We managed to get home just in time to cook lunch. The level of activity was greater than any recent morning (months and months of mornings!) …and I felt a little discombobulated! I’ve begun to enjoy the pace of pandemic life!

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: October 2020 – Starting out the weekly gleanings with birds.

Linking calorie restriction, body temperature and healthspan -- ScienceDaily – Interesting research. I went off on a tangent thinking about “up to half of what we eat every day is turned into energy simply to maintain our core body temperature.” Many people in the developed world spend the majority of time in temperature-controlled buildings or homes…and that means we probably expend a lot less calories warming or cooling ourselves than we did prior to efficient heating and cooling systems. Just one more way we are changing our environment in a way that will tweak our future evolution.

The super-adaptable chimps that can withstand climate change - BBC Future – I didn’t realize how many different habitats chimpanzees are found in…and that the ones that live in environments with greater seasonal change have more varied behaviors to respond to those changes than chimps that live in an environment that doesn’t change much.

Environmental Education Goes Virtual: Creating Meaningful Learning Opportunities at Home: The National Wildlife Federation Blog – So many good online resources…they’ve been developed over years but are probably getting a lot more use during this pandemic year.

It's Tarantula Season At Bandelier National Monument – I’ve not been to Bandelier during tarantula season! The last time I was there was in March 2005 and that was before I started taking a lot of pictures….this article reminded me that I want to go again. Maybe we’ll plan to go in the fall and be on the look out for the male tarantulas trying to find a mate. Here are a couple of pictures my husband took when we visited in 1980!

Are we living at the 'hinge of history'? - BBC Future – It’s difficult not to look at current trends and think the future will be a dystopian one with or without seeing this as a ‘hinge.’ The last paragraph was the best of the article: “So, while we do not know if our time will be the most influential or not, we can say with more certainty that we have increasing power to shape the lives and well-being of billions of people living tomorrow – for better and for worse. It will be for future historians to judge how wisely we used that influence.”

Why is America Running out of water? – Shortages are not everywhere…but there are places in the US that are already problematic…and there are a lot of people living in those areas.

Raptor Rescue: When Bird Injuries Warrant Rehab – This article was a good summary of things I’ve heard about before re injured birds.

Unusual climate conditions influenced WWI mortality and subsequent influenza pandemic -- ScienceDaily – Something new about the 1918 flu…torrential rains and unusually cold temperatures kept Mallard ducks from their normal migration…and thus spread the virus more broadly in the battlefields of the Western Front.

What 'net-zero carbon' really means for cities - BBC Future – Using London as an example: no/fewer cars and all transport EV, less concrete…more timber, buildings reused/retrofit, green roofs and walls, renewable energy, reduced waste through recycling and energy production, urban farms. It’s technology that exists now…and already is being applied…ramped up, of course.

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

The mystery of why some vaccines are doubly beneficial - BBC Future – Vaccines have ‘non-specific effects’ that provide benefits beyond keeping individuals from catching a disease. The examples in the article include studies of the measles vaccine in West Africa and the BCG vaccine for tuberculosis.

Meet the Goat Antelopes: Strange, Large Mammals of the Mountains – I remember seeing mountain goats with young in South Dakota in June 1997. My young daughter wanted to climb rocks like the goats! This article is about similar animals from all around the world.

Researchers Say Restricted Human Access At Cape Hatteras National Seashore Benefits Birds – Hurray for management of beaches to allow these birds to successfully raise their young!

The Medieval Archaeological Heritage Of Eastern Andalusia – 10 centuries of Medieval history in one place.

Read All About It: What's New In Home Energy Storage Research – An overview of the state-of-the-art in home energy storage…and important component in the transition to renewable energy.

The surprising dangers of cooking and cleaning - BBC Future – Thinking more about what we put into the air inside our home these days. The houses are better sealed and central heat/air means we don’t open our windows as frequently (if at all).

Record Flooding Threatens Millennia-Old Pyramids in Sudan | Smart News | Smithsonian Magazine – A part of Ancient Egyptian history in danger…flooding and then looting too.

Top 25 birds of the week: Colours - Wild Bird Revolution  - Can’t pass up the bird photos!

Macro Photos Take Us Inside the Enchanted World of Insects – Highlighting insects now…they are full of surprises. And are challenging to photograph too.

The World's Largest Chocolate Museum Debuts in Switzerland | Smart News | Smithsonian Magazine – 65,000 square feet of the Lindt Home of Chocolate….includes a production line. There is an animated video in the post since very few of us will get there anytime soon. We can buy Lindt chocolate though.

Gleanings of the Week Ending October 3, 2020

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.

Domesticated chickens have smaller brains -- ScienceDaily – 10 generations from wild junglefowl toward domestication….and they already had smaller brains.

750 Million GM Mosquitoes Will Be Released in the Florida Keys | The Scientist Magazine® - Reducing yellow fever and dengue carrying mosquitos at a time when more mosquitos are becoming resistant to pesticide-based controls. Texas might be the next place this technique will be used – pending state and local approval.

Earthquakes and insects on Alaska road trips - The Field - AGU Blogosphere – I browsed this article and remembered learning about the 1964 earthquake from the Weekly Reader in elementary school. So -this was an update about what the place is like today…with the town moved completely.

Nuvve And Blue Bird Combine To Create Electric School Buses That Are V2G Enabled – I wish all new school buses would be electric…and charged via renewable means…for the planet and, more directly, for healthier air for young lungs.

Top 25 birds of the week: Colours - Wild Bird Revolution – Beautiful birds….I never get tired of looking at images of the diversity in color and form the birds display.

The U.S. drought vulnerability rankings are in: How does your state compare? | NOAA Climate.gov – Looking at states that I know well because I have family members living there Maryland, Texas and Missouri have a high ability to adapt whereas Oklahoma has a very low ability to adapt (because they have an outdated drought plan and limited irrigation combined with extensive agriculture and cattle ranching). Is Oklahoma headed toward another dust bowl?

Five myths about wildfires - BBC Future – The 5 myths debunked in this article are: regularly logging forests prevents forest fires; there is nothing you can do to protect your property; wildfires are an inevitable fact of nature; all wildfires are bad and must be quenched immediately; it is possible to eradicate (control) all wildfires

Thousands of species recorded in a speck of soil -- ScienceDaily – DNA was extracted from permafrost samples representing different points in the Pleistocene - Halocene transition (about 11,000 years ago). Genetic remnants of animals like mammoths, horses, bison, reindeer along with 1000s of plant varieties were found!

The remarkable floating gardens of Bangladesh - BBC Future – Planting on floating rafts….large scale hydroponics that is not greenhouse based.

4 Fun + Informative (+Free) Apps for Upping Your Nature Knowledge – Cool Green Science – These are great Apps to id plants and animals quickly…with cell phone: SEEK, iNaturalist, Merlin, eBird.

Gleanings of the Week Ending September 26, 2020

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.

Closing the Racial Inequality Gaps – Citi Global Perspectives & Solutions – The report (summarized by NPR in Cost of Racism: US Economy Lost $16 Trillion Because of Discrimination, Bank Says) details the analysis  done by Citi that calculates the economic impact of racism….and thus puts a value on proposed government and individual actions to close racial gaps.

Top 25 Birds of the Week: Birds in Flight and Bird Interactions – Double the bird photos this week!

Infographic: Dialing Down the Glitz | The Scientist Magazine® - The mechanism that makes dramatic sexual dimorphism in some finches.

How vitamin C could help over 50s retain muscle mass -- ScienceDaily – Another reason to eat Vitamin C rich foods (and take a supplement when that is not possible).

A guide to natural sweeteners – in C&EN – Compound Interest – A good summary of the chemistry behind natural sweeteners. I am enjoying the stevia leaves I am getting from the CSA’s cutting garden right now – building up my supply a little every week of dried leaves and stems to enjoy even after the cutting garden ends for the year.

Schooling is critical for cognitive health throughout life -- ScienceDaily – Boosting cognitive skills early in life not only expands career opportunities and provides progressively higher salaries…it also pushes back the point at which age-related dementia begins to impact a person’s ability to care for themselves. Education is a good long-term investment for everyone.

Study Tracks Geographical Gene Flow and Ancestry in the US | The Scientist Magazine® - Beginning to get deeper genetic studies that might translate to better understanding of risk of disease across sub-populations within the US.

Scientists use fruit peel to turn old batteries into new -- ScienceDaily – Recycling metals from lithium-ion batteries with food waste…an example of the types of processes we need to develop for a circular economy (zero waste).

Hike in Walnut Canyon – A short video of a special place. I first visited in 1971 in the winter. It was memorable. Maybe I’ll go again after the pandemic is over; it’s high enough elevation I’ll make sure I am acclimated before I hike the trail to see the cliff dwellings up close.

The Undoing of US Climate Policy: The Emissions Impact of Trump-Era Rollbacks – Many young people see climate change as a high priority for the government to address….so do I. This research shows that the actions of the last few years have moved the US in the wrong direction. I usually prefer to focus on solutions and what individuals can do….but the government has a roll to play and, right now, it is moving opposite of the way needed.

Unique Activities for Yesterday:

Letter sweater. I found my 50-year-old letter sweater (academic…not sports) from high school when I cleaned out the coat closet. It still fits! It’s a little chilly today and I am wearing it. I took the letter off years ago but the flap in the pocket has my name embroidered on it. One of the buttons aged differently than the others – looks reddish rather than black. I’ll wear it as a basic black cardigan (with the odd button) in the fall and winter. I made a small pile of some other things in the closet to give away. My pile is big enough now that I am scheduling a pickup from my front porch!

Gleanings of the Week Ending September 19, 2020

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.

Asphalt adds to air pollution, especially on hot, sunny days -- ScienceDaily – Evidently, it’s not just fresh asphalt that pollutes air. In cities, pollution from asphalt is significant enough that it needs to be considered in efforts to reduce pollution. Because it is usually dark in color it also contributes to the heat island effect in cities.

The Peopling of South America | The Scientist Magazine® - Sites along both coasts of the continent…analyzed with modern technologies…teasing out more information about the waves of migration.

The fate of antiques and heirlooms in a disposable age - BBC Future – As we come more conscious of the impact of our lifestyle on the environment….maybe durability of our possessions becomes more important again.

Researchers identify five types of cat owner -- ScienceDaily – In this study…the types are defined in terms of their attitudes toward their pets’ roaming and hunting: conscientious caretakers, concerned protectors, tolerant guardians, laissez-faire guardians, and freedom defenders. My husband and I are in the 1st category although there is a component of the second in our attitude as well. We keep our elderly cat indoors or on the screen enclosed deck.

Think Pigeons Are Boring? Not These Birds – From around the world.

How we sleep today may forecast when Alzheimer's disease begins -- ScienceDaily – The study indicates that the amount of deep sleep (i.e. non-REM slow-wave sleep) is predictive of how restorative sleep is for the brain (as measured by the build up (or not) of beta-amyloid plaques). They haven’t yet done the next step: improving sleep quality and observing the impact on beta-amyloid plaques.

Botanical gardens - where nature meets science and society – A short history of botanical gardens of Europe.

Some of America's favorite produce crops may need to get a move on by 2045 -- ScienceDaily – A third of veggies and two thirds of fruits/nuts consumed in the US are grown in California. In 20 years, climate change will make much of the area hotter and drier. The study looked at 5 crops (lettuce, broccoli, carrots, tomatoes, and cantaloupe) that make up 64% of California’s cash value of veggies/melons. In the future, cool season crops (like broccoli and lettuce) will be grown not just in fall and spring…but in the winter too. It will be too warm to continue growing tomatoes during the summer as that they are grown now and it could be challenging to find a 4 month period where the temperature is in a good range for tomatoes. The main message of the study is that planning needs to be done now to maintain food production in the US.

Eat, Prey, Love: Fast Facts on the Remarkable Praying Mantis – Mantises are fascinating insects. I listened to a video  recently about hummingbirds from one of the birding festivals that talked about mantises sometimes eating hummingbirds!

Playfulness can be trained - here's why you should do it -- ScienceDaily – Applying interventions of positive psychology to playfulness. It appeals to me that the study is coming out now when we have so many people in awkward situations trying to stay healthy. Increasing playfulness was found to improve mood!

Home Valuation Needs to Consider the Risk of Climate Change - News | Planetizen – The piece is focused on sea-level rise but there are other climate change factors that might also need to be considered: increasing drought (i.e. some places that won’t have enough water to support the population living there) and – perhaps related – extreme heat/fire risk. Our government should not be willing to buy increasingly risky mortgages through Fannie Mae and Freddie Mac.

Cassowary Quest: A Tale of Danger and Defecation – Learn a bit about the cassowary – great picture and video too.

American Academy of Sleep Medicine calls for elimination of daylight-saving time -- ScienceDaily – I hope the drive to not switch times begins to gain momentum. It’s annoying – and not healthy for us either.

Dragonflies the Star of Photography Book About Their Lifecycle – We didn’t get to Kenilworth Aquatic Gardens this year to photograph dragonflies (along with the lotuses). These pictures are awesome….and encourage me to think about spending more time near ponds next summer.

The rare plants that ‘bleed’ nickel - BBC Future – Phyto-mining may be an alternative to using heavy machinery, destroying an ecosystem, and producing toxic waste. Hopefully, the work being done now will quickly become the dominate way to mine nickel.

A Field Guide to Finding Cool Moths – Mothing is (not yet) as popular as birding. The techniques discussed in this article are a good start. I’m going to try leaving the porchlight on tonight – checking around it before I go to bed and then again when I first get up (when it’s still dark outside). I’ve seen and photographed several of the moths mentioned in the article:

Hummingbird moth (Maryland in 2016)

Understanding how birds respond to extreme weather can inform conservation efforts -- ScienceDaily – An example of how scientists use the data submitted by a large number of people into eBird to answer questions re the impact of climate change and the resilience of birds (or lack of resilience).  

Unique Activities for Yesterday:

Prius Prime maintenance. The miles put on the car since the last service were minimal, but it was time for the maintenance. Everyone at the dealership was wearing masks but there didn’t seem to be any hand sanitizer stations (I was glad I had brought my own). I brought disinfectant wipes for the inside car surfaces when I picked up the car and then drove away with the windows open to clear out the air in the car….continued to wear my mask for most of the drive home.  

I’ve about used up the tank of gas I bought 9 months ago so I’ll fill it up and start plugging it in again to do all my errands with it as an EV. I hope there is a vaccine available by the end of the year --- and I’ll be out and about a lot more.

Mini-clover update. We’ve had gentle rain for the past few days and temperatures in the low 70s into the 80s. The clover is a cloud of tiny of green leaves on the surface of the bare spots in our yard. This is evidently good clover growing weather!

Monarch Caterpillar update. I only found one caterpillar this morning and it hasn’t moved much since I saw it yesterday. It’s large…hope it is about ready to make a chrysalis.

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 cavemen needed no braces – Our diet and behavior have changed a lot since the stone and hunter/gather stages of our species….and those changes have impacted our jaw (and teeth and air way). There are more health consequences than just crooked teeth. I’ve bought the book (Kindle version) to learn more.

Characteristics that give viruses pandemic potential – An article from The Scientist that is more future oriented. What we are experiencing with COVID-19 is something that could happen again. The article talks about various types of viruses that pose the greatest threats.

Peer into the Past with Photorealistic Portraits of Roman Emperors – Taking historical sculptures and drawings to the next level. The Smithsonian Magazine summary has images of Augustus, Maximus Thrax, Caligula, and Nero….the rest can be viewed in Daniel Voshart’s site.

Amazing Macro Winners of the International Garden Photographer of the Year 2020 – Visual treats. This it the type post that gives me ideas about things to try with my own camera.

1,200-Year-Old Soap Factory Unearthed in Negev Desert – The soap was made from olive oil and the ashes of the saltwort plant. The factory produced enough for export to places like Egypt and other parts of the Arab world.

Low humidity increases COVID-19 risk: Another reason to wear a mask – This finding does not bode well for the winter when many homes and workplaces have much lower humidity because of furnaces.

Top 25 birds of the week: Birds in Pairs – Beautiful birds….I always enjoy looking at the 25 pictures each week.

Hawaiʻian Snails: A Tale of Discovery and Rediscovery – I remember seeing a snail in a planter box at the airport on the big island while I was waiting for my luggage a few years ago…and I dug up the picture I took when this article prompted the memory.

Wolverines Seen Roaming About Mount Rainier National Park – What a boon remotely triggered cameras can be….and then DNA testing of hair to determine relationships!

 Meet the Squad of Mosquito-Eating Species – Birds, dragonflies, newts, aquatic turtles, and bats. We haven’t noticed very many mosquitoes around this year, but we try to replace the water in our bird baths frequently and make sure our gutters are draining properly. Having the birds around our house probably helps…and the turtles at the neighborhood pond do their part.

Unique Activities for Yesterday:

Going to the basement during a storm. Our phones went off with tornado warnings – which is rare in Maryland. We went to the basement. It turned out to be only heavy rain for us (not very windy either); to the east and south of where we live there was a lot of damage with trees/big branches falling and shingles flying.

Cleaning the leaves off the deck. Over the past week we’ve had several fronts come through that have blown leaves and branches onto our deck. They were still wet when I went out to clean up. I dumped the sediment that had accumulated in the bird bath too.

Finding Witches’ Butter. I photographed the fruiting bodies of Witches’ Butter on our deck railing. The deck is over 25 years old and even regular treatment can’t keep it clear for fungus; it is only visible during times when the wood is wet for several days.  

I’m more concerned about a window frame that has the same fungus growing. I’m not keen about replacing the window but we might have to consider it.

On the Delaware, A Promising New Era in Cleanup of an Urban River – Like many urban rivers in the US – a lot of progress has been made since the mid-20th century….but there is still a ways to go. Many of the urban rivers are clean enough in some stretches for recreational use….but often not after storms when sewage systems and extra industrial waste might be in the water along with the storm water.

Are you being served? A short history of waiters and servers in restaurants – Many of us are still in the mode of only getting carry out!

Examining the Chemistry of Yellowstone National Park's Thermal Waters – A little chemistry lesson in this post. Many of the hot springs and geysers are basic…mud pots and steam-driven fumaroles are acidic.

U.S. Commercial Rooftops Hold 145 Gigawatts of Untapped Solar Potential – The big challenge is logistical and financial. It seems that a partnership between commercial properties and community/utility solar would be worthwhile. It would be much better to use commercial rooftops than farmland for solar panels and many of the rooftops are in areas that consume a lot of electricity as well.

Record-Breaking 60,000 Flamingos Flock to Southern France -The picture of an adult flamingo surrounded by babies/juveniles caught my attention. I didn’t know that young flamingos are gray!

Unique Activities for Yesterday:

Flu shot. I got to my grocery store’s pharmacy just after they opened at 8:30 AM – got a flu shot. The store was busier than when I do my grocery shopping staring around 6:30….but it was still mostly possible to social distance…and everyone was wearing masks. I’ll stick with the earlier time for my grocery shopping.

Alaska’s Vegetation is Changing Dramatically – The impact is still to be determined but rapid changes are rarely good for ecosystems….they decline because they can’t adjust fast enough to the rate of change.

Bees' buzz is more powerful for pollination, than for defense or flight -- ScienceDaily – There is not just one kind of buzz! And some bees (like honey bees) don’t buzz flowers at all.

Top 25 Birds of the Week: Raptors  - The birds of prey…some are powerful looking, some are cute, some a ugly…but that’s just overlaying our stereotyping onto birds like we do with other people.

Why Plastic Waste is an ideal building material – We need a strategy to upcycle all the waste plastic that is accumulating since we don’t seem to be able to wean ourselves from plastic packaging at all.

Grand Canyon's Prehistoric Past Appears In 313-Million-Year-Old Tracks -  Sandstone rockfalls….near the trail…first spotted by a Norwegian geology professor on a field trip to the Grand Canyon with his students.

Unique Activities for Yesterday:

Clothes dryer working. Our 20-year-old clothes dryer has a new heating element and the dust/lint has been cleaned out from around the innards. The first loads we did were towels!

Doe and 2 fawns in our back yard. My husband noticed the deer in our back yard in the afternoon. They stayed around long enough for me to get some pictures. In past years we’ve had a doe and 2 fawns in our yard more frequently. This year their main path back into the forest must be through another yard because we haven’t seen them as often…and so it is a special day when we do.

The fawns are good size now, but their spots are still noticeable…not quite as well defined as earlier in the season.

New fabric could help keep you cool in the summer, even without A/C -- ScienceDaily – Interesting. But are there some negatives to ‘nanofibrous membranes’? Could they be worse pollutants than microplastics if we aren’t careful with them?

Photography in The National Parks: Gearing Up, Staying Safe, And Getting Back Out There with My Cameras at Crater Lake National Park  - I’m still not confident enough to try a road trip to a national park when I am still carefully timing my trips to the grocery store! I’d have to purchase a lot more masks than I have now --- and develop a strategy for ‘rest’ stops along the way.   

Older adults coped with pandemic best, study reveals -- ScienceDaily – This study seems intuitive to me. My husband and I are in the over 65 crowd and post-career. We miss volunteering and traveling…but we are not anxious about a job or childcare or facing financial catastrophe. 2020 is a going to be an odd year for us…but not a bad one. It’s not hard to laugh about not knowing when we’ll get a haircut!

Forest Photos Captured in Different Seasons Shows the Beauty of Change – Interesting idea of a long-term photography project. I’ll have to start scouting some places easy for me to get to.

Childhood connection to nature has many benefits but is not universally positive, finds review: A connection to nature is complex, as well as positive emotions, it can generate negative emotions linked to issues like climate change -- ScienceDaily – But those negative emotions can lead to actions toward a more livable world….which would net to a positive in the long run.

Unique Activities for Yesterday:

Cicada on the Screen. There don’t seem to be as many cicadas around this year. I hear one occasionally…but no answering song. I hope they are finding mates but would be more confident if there were the usual overlapping songs. There was one on the screen of our covered deck in the early morning. It must have spent the night there and it was not quite warm enough for it to be singing. Later in the day it was gone.

Unique Activities for Yesterday:

3 racoons. Our birdfeeder camera made a video of some visitors to our deck just before 2 AM on Wednesday, 8/5: three racoons! They looked smaller than the female that came several times earlier in the summer. Perhaps they were her young….out foraging on their own (maybe she was nearby). They were no more successful than she was getting seed from our squirrel proof birdfeeder! The action started with one up on the deck railing under the feeder and another 2 directly below on the deck floor. The one on the railing comes down almost on top of one that was on the deck floor. The one that was on the deck railing stayed in the video the longest…thoroughly searching under the feeder after going down to the deck floor.

Sycamore branch. Back on August 2nd I posted about a dead branch in our Sycamore tree (picture on the left). My husband discovered the branch on the ground near the base of the tree when he went out to use the weed eater and it took both of us to pulled it to our brush pile at the edge of the forest. It came down without bringing a lot of other branches with it….a little sooner than I expected but probably brought on by the thunderstorms that have been sweeping through the past few days.

Yellow wooly bear. My sister sent me a picture of a caterpillar from her garden in Carrollton, Texas. It appears to be a yellow wooly bear that becomes a Virginian Tiger Moth. Evidently, they are common but neither one of us had seen one before.

Identifying sources of deadly air pollution in the United States -- ScienceDaily – Focusing on fine particulates associated with heart attacks, strokes, lung cancer, and other diseases…about half comes from burning fossil fuels; the other half is from animal agriculture, dust from construction and roads, and burning wood for heating/cooking. Ammonia is one pollutant that is not regulated as much as the others and yet it causes a 5th of all deaths caused by fine particulates. It could be reduced with targeted manure management and improving formulations of cleaning supplies, paints, and inks, etc.

Results group into 3 types of biosignatures: biomineralization, tissue, and phylogenic.

Infographic: What Social Isolation Can Mean for the Brain | The Scientist Magazine® - I wondered if the brain structural observations were a cause or effect (or neither). Does the observation that people who are lonely have smaller amygdalae because that are isolated or because they were born that way and it wouldn’t matter if there were a lot of people interacting with them…they would always feel lonely/isolated.

A Silk Road Renaissance - Archaeology Magazine – Many more commodities than silk on the ‘silk’ road: jade, glass, spices, metalwork, ceramic….and missionaries. And the Sogdians were the people that made it work from the 5th to 8th centuries. Panjakent, in modern Tajikistan, has been excavated since the 1940s; many murals have been found depicting myths, fables and everyday life of the Sogdians. In 755 a failed Sogdian coup against the Chinese emperor and thereafter incursion of Arabs from their west caused the culture to fade.

Unique Activities for Yesterday:

Blue Jay Behavior.  There was a blue jay on the deck railing making noise….fluttering its wings…making eye contact with 3 or 4 other blue jays around at the time. Those other jays seemed to ignore the ruckus and flew away. Then the bird flew down to the floor of the deck to look for seeds. Maybe it was a fledgling wanting to be fed by the adults…but the adults were forcing the young bird to find its own food? I’m not sure…but I enjoyed witnessing the minute or so of action…whatever it was about. Maybe it was the same jay that tried to get seed from our bird feeder a few days ago (and failed).

Compost bin. Between rain showers – I put on the boots I have for river field trips and got all my containers of kitchen scraps and spent flower stalks (mostly day lilies) out to the compost bin. It took 4 trips! There have been more things recently that produced more kitchen scraps than usual: fresh corn on the cob, cantaloupe, cabbage cores, and tough onion/leek tops. I’ve learned to save cucumber skins for use in smoothies so those get eaten these days and veggies like beets and carrots just get a thorough scrubbing rather than being peeled. I put all the new scraps on one side of the bin and then turned the other side over on top of it. I should deteriorate very rapidly.

Gleanings of the Week Ending July 18, 2020

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.

Listening to Silence: Why We Must Protect the World’s Quiet Places - Yale E360 – I realized after 9/11 that most of the modern world sounds at my house are from transportation: planes/helicopters and cars/trucks with occasional yard equipment. While we had a stay-at-home order with this pandemic, it became noticeable as well. There are still times when those noises are subdued or gone. I notice the bird songs in the early morning…when the other sounds don’t intrude. As we skew more toward electric ground transportation….the noise level will notch downward. I enjoy the natural sounds a lot more than our man-made ones.

Declining eyesight improved by looking at deep red light -- ScienceDaily – I wonder if this is something doctors will start prescribing!

Why your organs might reach 100 even if you don't - BBC Future – A summary of some current research areas re aging. There are a lot of different approaches with the primary goal of most being to extend healthy lifespan.  Even if different organs age at different rates…they are interrelated to the body they comprise.

Maryland offshore wind farm could become stop-over for migrating sturgeon, striped bass -- ScienceDaily – I live in Maryland….so this story grabbed my attention. Will the offshore windfarm become a rest stop for fish? And they will offer a convenient infrastructure for researchers to collect data.

Where Will Climate Migrants Go? – THE DIRT – It’s something to think about now. Some coastal cities are already experiencing more flooding even without unusual storm events…and people that can move will probably do so. Will climate trends weigh in decisions about where they move? The article talks about cities and towns in the Midwest that have experienced declining population becoming ‘receiver’ locations. I wondered if people that have discovered that they can work from home during the pandemic – and can continue to do so – will be freer to move to these new locations and still have the same employer! Otherwise there is the challenge of how to sync moving to a new place with a new job.

The chemistry of cats: Allergies, catnip and urine – Compound Interest – Evidently male cats produce higher levels of allergen and have smellier urine…unless they have been neutered.

Ways to keep buildings cool with improved super white paints -- ScienceDaily – White roofs should probably become the norm….it will be hot enough without the added heat island effect caused by a lot of man-made structures with dark roofs.

How humans are altering the tides of the oceans - BBC Future – It’s happening around the world. Dredging river channels and filling in coastal wetlands cause shifts in how tides interact with the land. And then there is sea level rise too. Some places cited in the article that have experienced dramatic change: Cape Fear River in North Carolina (tidal range at Wilmington has doubled since 1880) and the same is true for St. Johns River/Jacksonville Florida. Sacramento’s tides disappeared in the late 1800s because of silt but dredging brought them back and the Thames tidal range was 2 meters during Roman times and 8 meters by the Victorian age.

Meet the Mountain Chickadee – We have mostly Carolina Chickadees where I live in Maryland…this is their relative in the western US (mountains).

Ancient Maya reservoirs contained toxic pollution: Mercury, algae made water undrinkable in heart of city -- ScienceDaily – Mercury from pigments used on Mayan building. Cyanobacteria blooms that made the water smelly and toxic. Not pleasant for a city center!

Unique Activities for Yesterday:

Regenerative Landscaping lecture (via zoom). The lecture was about an hour and my big take away was about the huge environment cost of lawns…and the many dimensions of that cost. The one I hadn’t thought much about before was from the California Air Resources Board fact sheet on Small engines in California (small engines being spark-ignition engines in things like lawn mowers). Their fact sheet says: “In the early 2020s, however, total smog-forming emissions from small engines are projected to exceed those from passenger cars in the South Coast Air Basin because passenger car emissions will continue to decrease. By 2031, small engine emissions will be more than twice those from passenger cars.” For comparison – they show 1 hour of lawn mowing emits as much smog-forming pollution as driving a Toyota Camry 300 miles! This must be an issue in all areas where there is a lot of mowed turf grass – kike most suburbs. There are multiple ways to address the problem and the one discussed in the meeting was transitioning to less lawn or lawn that does not need to be mowed as frequently (or at all). Another way would be to transition to electric mowers and other yard equipment. Right now – the only gasoline powered equipment I have is the mower. I’d been thinking about an electric mower because I don’t like the noise and smell of our current machine. So - this overall air quality issue is just one more reason to do it.

Enjoyed a slideshow of Armand Guillaumin (1841 – 1927) paintings available on Internet Archive here. He was a French impressionist painter and lithographer.
