Gleanings of the Week Ending February 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.

Human egg cells are imperfect surprisingly often -- ScienceDaily – More than 7% of human oocytes contain at least one exchangeless chromosome pair…and the frequency is not affected by maternal age. Our species is hardwired to have significant numbers of miscarriages and babies with extra or missing chromosomes. The finding is interesting, but I immediately thought of some questions…has this changed over the past 100 years (i.e. have we changed our environment enough that we are impacting our reproductive success) and how does this frequency compare to other mammals?

Why our pursuit of happiness may be flawed - BBC Future – A thought provoking piece about how seeking ‘happiness’ often sets the stage for disappointment…rather than contentment.

Pollution from cooking remains in atmosphere for longer -- ScienceDaily – Eating deep-fat fried foods is not just unhealthy…the cooking of foods that way contributes to air pollution. In London, 10% of the PM2.5 particles are from deep fat frying….in Hong Kong 39%!

2nd Annual Threatened And Endangered Parks: Natural Darkness And Sounds – My husband and I are looking forward to more dark sky opportunities in national parks. So far – the ‘star parties’ we’ve been to have been at state parks and hosted by amateur astronomy clubs in the area. The dark sky venue requires a bit of infrastructure to support a field full of camping amateur astronomers with their telescopes (electricity for telescopes/computers and bath rooms with red tented windows).

Top 25 birds of the week: Colouration! - Wild Bird Revolution – Lots of color in this post to break up mostly brown and white winter color outside my window! 

U.S. Breaks Record for Billion-Dollar Climate Disasters in 2020 | Smart News | Smithsonian Magazine – Not a good record to be breaking…and they happened during a pandemic year too. There were 22 disasters that caused at least $1 billion in damages across America in 2020.

Q&A: Global Insect Declines Due to "Death by a Thousand Cuts" | The Scientist Magazine® - In every case researched….it’s not just one thing that caused the decline…it a cluster of primary factors (6 or more) and then other factors that are difficult to quantify.

Texas Wind Power Dominates Coal In Crossover Year – Hurray! Hopefully, the coal plants will begin to phase out in Texas and across the country as they become less and less competitive with renewable sources of power.

On the road to invisible solar panels: How tomorrow's windows will generate electricity -- ScienceDaily – I am always reluctant to consider replacement windows….but if they were cost effective solar panels…that would tip the decision toward ‘buy’!

Caligula's Gardens, Long Hidden Beneath Italian Apartment Building, to Go on View | Smart News | Smithsonian Magazine – A subterranean museum beneath the streets of Rome to open this spring.

I am featuring videos this week….including the newest baby panda in the US and historic houses. I discovered that a lot of house-type museums have increased their virtual content during the pandemic. The historic houses I picked for this post are ones I have visited in the past. Some I have visited more than once (Mount Vernon and Monticello, for example). It’s fun to savor them virtually!

Panda Cub’s virtual debut – From the National Zoo…video is just over 2 minutes

Virtual visits to the Newport Mansions -  3D tours From the Preservation Society of Newport County. Includes The Elms, Marble House, Hunter House, Isaac Bell House, Chateau-ser-Mer, Chepstow, and Kingscote.

The Mark Twain House in Hartford, CT – 3D tour

Mount Vernon – George Washington’s house. 3D of the gardens and mansion

Lyndhurst – Several 3D views….including at Christmas and Halloween

Vizcaya Museum and Gardens – Florida. 3D with links to historic photos of the same area

Monticello – Thomas Jefferson’s house. 3D tour. There is also a Google Arts and Culture tour with video/photos.

Olana’s Historic Landscape Video Tour – Frederic  and Isabel Church home.

Val-Kill tour – Eleanor Roosevelt National Historic Site from Google Arts and Culture

Wilderstein – Online exhibit, aerial tour, and landscape tour. The house was the Suckley residence for 3 generations from 1852 to 1991.

Ice sheet uncertainties could mean sea level will rise more than predicted -- ScienceDaily – There are warning signs that the current models aren’t accurately predicting ice sheet dynamics.

How mail-order frogs could save Colombia's amphibians - BBC Future – Carefully breeding frogs to keep them from going extinct in the wild.

Meet Amanda Gorman, the U.S.' Youngest Inaugural Poet | Smart News | Smithsonian Magazine – Leading with eloquence and hope for the future….pushing us to strive for a country that is a ‘more perfect union.’

House Agrees Saguaro National Park Should Grow By 1,200 Acres – Hope this happens…when my daughter was in Tucson we enjoyed this park many times.

Diet and lifestyle guidelines can greatly reduce gastroesophageal reflux disease symptoms -- ScienceDaily – Exercise seems to be important – perhaps because it helps clear stomach acid that causes heartburn symptoms.

Top 25 birds of the week: Wild birds Photos! - Wild Bird Revolution – Birds – always great to look at in the wild and in photos.

How Codebreaker Elizebeth Friedman Broke Up a Nazi Spy Ring | Smart News | Smithsonian Magazine – Some history…about how a woman did work she wanted to do…made significant contributions…didn’t get credit or pay that she should have. It happens again and again. We can’t assume that it isn’t still happening just because we have some very visible examples of women with power, recognition, and pay.

Are sleep trackers accurate? Here's what researchers currently know – It’s not always good to track sleep….particularly if it causes anxiety. I am in the group that generally has good sleep, so the tracker data doesn’t cause me anxiety, but it probably doesn’t improve anything either!  I might get a much simpler tracker next time that doesn’t provide sleep metrics.

The Wintertime Wonder of Unusual Ice | Smart News | Smithsonian Magazine – The short video of hair ice forming is interesting.

How Africa's largest city is staying afloat - BBC Future – Lagos, Nigeria. Part of the city is known as the ‘Venice of Africa.’ And there is a ‘Great Wall of Lagos’ to reinforce the coast.  The claim is that Africa’s largest city is leveraging its ingenuity to stay afloat….but whether it succeeds in the coming decades will be the real test.

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.

Wingspan and Other Tabletop Games for Naturalists – A new indoor activity for during the winter?

Square Structure Detected Under Monte Albán’s Main Plaza - Archaeology Magazine – The plaza was in use for 1,000 years….and evidently the structure detected with ground penetrating radar, electrical resistance and gradiometery is 60x60 feet…and about 3 feet thick. More study of the data might reveal if the building had stairs, tunnels, and columns.

Leaf microbiomes are a neighborhood affair in northern forests -- ScienceDaily – The microbes associated with trees have been an active research area in recent years. This study looked at Sugar Maples and discovered that their microbiome was similar to the trees around them…whether it was other sugar maples or conifers….other species entirely.

A warm pool in the Indo-Pacific Ocean has almost doubled in size, changing global rainfall patterns | NOAA Climate.gov – The impacts on large-scale atmospheric circulation and rainfall are expected to intensify in the future.

Top 25 birds of the week: January 2021 – This collection includes a photo of a red-breasted nuthatch…a bird we’ve seen at our feeder this year!

Photographer Nathan Myhrvold Captures Snowflakes in High Resolution – I enjoy trying to photograph snowflakes…but I do it close to home where the challenge is higher temperatures. That tends to cause them to clump rather than be easily separated into single flakes. It’s still a fun activity for snow days.

New mammogram measures of breast cancer risk could revolutionize screening -- ScienceDaily – Improving the way mammograms are analyzed…giving results at the time of screening instead of later then moving toward personalized screening thereafter rather than ‘one size fits all.’ I wonder how long it will take for this to trickle through the industry.

Flapper style | Europeana – Our family has a picture of one of my grandmothers in a flapper dress. She probably made it herself – as the article indicated…they were easy to make and patterns were available. The dresses have a timelessness to them even though they are associated with the 1920s. They look great as party dresses even 100 years later!

'Sparkling' clean water from nanodiamond-embedded membrane filters -- ScienceDaily – The problem the researchers are addressing is filtering of the hot water from oil recovery and other industrial processes. We’ll need more technologies like this to clean up water we can’t afford to leave polluted forever….but we should concurrently move toward technologies that don’t leave toxins in water. Technologies should be designed with the goal in mind of 0 waste.

Researchers Catch Oldest Tropical Reef Fish Known to Science | Smart News | Smithsonian Magazine – An 81-year-old midnight snapper! They also caught a 79-year-old red snapper in the same area. Climate change is already warmed the reef enough that the life-span of the fishes there is expected to be shorter in the future. The record for oldest known vertebrate in the world is also a sea creature – a 400 year old Greenland shark.

Gleanings of the Week Ending January 9, 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.

Coronavirus FAQ: How Do I Protect Myself From The U.K. Variant? - I added this one at the last minute…it’s scary…a good prompt to evaluate the precautions you are taking to not get COVID-19 with this more contagious variant circulating in the US. We are so close to having vaccinations broadly available!

When Only a Hippopotamus Will Do – Learn a bit about hippos. Did you know that there is a ‘wild’ population of hippos in Columbia’s Magdalena River, escaped from Pablo Escobar’s menagerie after his death?

Plastics pose threat to human health, report shows -- ScienceDaily – Awful….and there is relatively little being done to control this source of toxins in our environment.

Top 25 birds of the week: Terrestrial Birds! - Wild Bird Revolution – Most of the birds are relatively drab – lots of browns and off-white feathers….but interesting patterns. - the better to blend in with their environment. But there are a few surprises that are quite different from the rest.

From Ancient Rome to Contemporary Singapore: The Evolution of Conservatories – THE DIRT – I like conservatories….this article includes some history that I hadn’t thought about before…a bit more from the perspective of how conservatories fit into the cultures that created them.

Operation Ponderosa: Saving a Forest, Pandemic Edition – Several reasons this article caught my attention: it’s about 1) the Davis Mountains in Texas…a location I’ve driven through on road trips between Dallas and Tucson, 2) fieldwork and also done by a woman during this pandemic year, 3) the Ponderosa pine’s importance as ‘sky islands’ in this arid part of the country, 4) the impact of fire, and 5) how genetic testing informs forest restoration efforts.

Trees are out of equilibrium with climate -- ScienceDaily – I might have gotten a bit stuck on trees for this gleanings collection. This study found that factors other than climate often limit where trees grow...that few trees grow everywhere the climate would appear to support their growth.

Ancestral Puebloans Survived Droughts by Collecting Water from Icy Lava Tubes | Smart News | Smithsonian Magazine – New Mexico’s El Malpais….a place I’ve visited several times.

Migration and disease in the Iron Age - Current Archaeology – A skeleton of a man with tuberculosis that died between 400 BC and 230 BC in Britain but was born elsewhere based on analysis of his molars that developed in early childhood. Did he contract the disease early in his life or after he arrived in Britain?

Canyon De Chelly, Walnut Canyon Park Pages Added to Traveler – I’ve been to both these places so was glad they were added list of Essential Park Guides on this site. The guides are collections of articles about each park…and good references when planning a visit or to see some pictures of the park!

Bowerbirds: Meet the bird world’s kleptomaniac love architects – Elaborate structures of sticks and often colorful found objects…to attract a mate.

Gleanings of the Week Ending January 2, 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.

2020 Year In Review: Top Stories From Around The National Park System – Issues discussed in the post: COVID-19, Great American Outdoors Act, border wall, invasive species, wildlife issues, climate change, crowding in the parks, wildfires.

New Discoveries in Human Anatomy | The Scientist Magazine® - So much study of human anatomy over the years….and there are still new discoveries.

50 Satellite Images from 50 Years of NOAA | NOAA National Environmental Satellite, Data, and Information Service (NESDIS) – Visuals from NOAA – beauty, science, education….so much has happened over the 50 years of NOAA’s existence.

2020 Year In Review: Parks, A Pandemic, And Photography – Lots to see in the National Parks…I hope to be able to get out and see some in-person before the end of 2021.

Top 25 birds of the week: Birding! – Wild Bird Revolution  - And I want to travel to some birding festivals too!

Recycled concrete could be a sustainable way to keep rubble out of landfill: Can even outperform traditional construction, says researcher – ScienceDaily – A Canadian study…seems like the results should be pertinent to the US too. The research indicates that “recycled concrete can be a 100% substitute for non-structural applications”….and might also be a substitute within more structural applications as well if innovations in the composition of recycled concrete continue.

Top 10 States For Renewable Energy, & Their Renewable Energy Splits  - Interesting mix of states on the list with quite a difference in the amount of hydro, wind, solar, geothermal, and biomass among the top 10. California is the only one with all 5. But there are 5 states that have 4 of the 5.

Scientists reverse age-related vision loss, eye damage from glaucoma in mice – ScienceDaily – Hopefully this research will translate into treatment for people.

Take a Virtual Tour of the World’s Largest Circular Tomb, Augustus’ Mausoleum | Smart News | Smithsonian Magazine – The virtual tour takes a little bit to load….but is worth it. Note that the ‘chapters’ are along the bottom of the screen.

Desalination breakthrough could lead to cheaper water filtration – ScienceDaily – Increasing efficiency of reverse osmosis filters by beginning to better understand how they work. This is something that will be more important as climate change and our own production of pollutants makes obtaining clean water more challenging.

35 Beautiful Winter Scenes to Get You in the Holiday Spirit – We had our first snow a little over a week ago…our Christmas was windy and rainy….I enjoyed these snowy pictures from around the world to get me back into the ‘winter wonderland’ mood.

Time capsule for 2020: the 37 objects that defined the year – This prompted me to think about what objects represent the year for me…maybe just a top 10 though rather than 37!

Top 10 Discoveries of the decade – From Archeology magazine

NOAA Research’s top 5 stories from 2020 – NOAA models track smoke movement – and locust swarms; scientists explore the impact of the COVID-19 response on the environment; carbon dioxide continues to rise; Dungeness crab larvae are already showing effects of ocean acidification; and a new roadmap for tracking ocean and Great Lake acidification

Top 11 Clean Energy Developments in 2020 – Some good news….nice to find these in a year that was dominated by bad – sad – horrific news (pandemic, fires, hurricanes, cultural/political strife).

Glucosamine may reduce overall death rates as effectively as regular exercise, study suggests -- ScienceDaily – It’s a correlation finding…not cause/effect. But the correlation was found by assessing data from over 16 thousand people over 40 years of age.

In boost for renewables, grid-scale battery storage is on the rise – Another good news story.

Photography in the National Parks: Winter Wonderlands – More wintery pictures of beautiful places.

Stonehenge's Continental Cousin - Archaeology Magazine – Archaeology in a German potato field! Evidence of concentric rings of oak posts, graves, pits filled with sacrifices, a village of long houses near the circle, alignment with sunrise on days halfway the solstices and equinoxes….no fortification.

Top 25 birds of the week: Bird Camouflage – Ending this gleaning list with birds. There lots of birds that blend into their environment!

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 Has Photography's Relationship With Nature Evolved Over the Past 200 Years? | Smart News | Smithsonian Magazine – A little history…that I used as a prompt to look for some of the works on Internet Archive. I’ll post about what I found for Kazumas Ogawa in a post next week.

Infographic: Deciphering Diet from Blood and Urine Samples | The Scientist Magazine® - Full article also available and more interesting that the infographic! The approach is still not perfected…but it may eventually help us get to personalized nutrition plans without as much trial and error that is required now.

Connection between gut bacteria and vitamin D levels -- ScienceDaily – Lots more needed to understand Vitamin D. This study indicated that blood tests for Vitamin D might not be useful at all since they don’t measure active Vitamin D….and active vitamin D is what correlates to gut bacteria…and potentially bone health. “Maybe it’s not how much vitamin D you supplement with, but how you encourage your body to use it.”

Get a Bird's-Eye View of UNESCO World Heritage Sites Across the Globe – Some beautiful places…from overhead.

How Non-Native Plants Are Contributing to a Global Insect Decline - Yale E360 – Insect declines….then birds. Lots of reasons to focus on planting natives a much as we can. I’m glad the forest behind my house is full of native trees and that I’ve replaced 2 bushs in the front of my house with natives. The challenge is to control the small but prolific invasive plants growing on the forest floor and into our yard enough for non-natives to survive. There used to be native jack-in-the-pulpits in our forest until several years ago.

How do we separate the factual from the possible? New research shows how our brain responds to both -- ScienceDaily – This article was frustrating. The study found that factual language is something our brains respond to. That’s not the issue at this moment in our nation’s history. The problem is the use of factual language about something not factual! Maybe this article is why we need to be more worried about public discourse/pronouncements.

It's One Hot Place Deep Down On The Floor Of Yellowstone Lake – About studies at Yellowstone Lake…the sensors and what they are revealing.

Shuttering fossil fuel power plants may cost less than expected -- ScienceDaily – Interesting…but I hope we’ll retire them all well before 2035 with the cost of renewals coming down so quickly. It will make economic sense to just do it!

Keeping Black Bears Wild And People Safe – This article is about black bears in Smokey Mountains National Park and the BearWise program more broadly. We do have Black Bears in Maryland and they occasionally show up in our area; there was one that showed up at our nearby elementary school a few years ago – caused a school lockdown until it wondered off.

Meet the Dipper, the Songbird That Swims – Evidently they are easier to spot in Colorado during the winter when they are concentrated long streams that remain unfrozen…but they are in the Rockies all year round…Dippers are elevation migrants (higher in the summer….lower in the winter). Maybe some post-pandemic trip we’ll look for them!

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.

Massive Arecibo Telescope Collapses in Puerto Rico | Smart News | Smithsonian Magazine – Very sad. It was already being decommissioned which was wrenching….but then the collapse meant that even the instruments that might have been usable elsewhere were destroyed. My husband spent some time at Arecibo during his graduate school studies in the 1970s.

What do slight arm movements reveal about our breathing and health? -- ScienceDaily – Evidently it works best during sleep when there is not a lot of other movement other than breathing!

Hegra, an Ancient City in Saudi Arabia Untouched for Millennia, Makes Its Public Debut | Travel | Smithsonian Magazine – Undisturbed for 2,000 years…once an international trade hub although most of the surviving structures are tombs…a few hundred miles to the south of Petra

Proterra Sells Its 1,000th Electric Bus and New Electric School Buses In Virginia & Massachusetts – Electric buses are very appealing…I’ve always hated the sooty exhaust from diesel buses. Buses operate in situations where many people (and children) are in close proximity, so removing buses as a source of city and school pollution would be a good step forward.

Glyphosate may affect human gut microbiota -- ScienceDaily – A bioinformatics tool to predict if a microbe is sensitive to glyphosate – in the soil…in the digestive system of animals. The compound, widely used as a herbicide, biochemically targets plants but the same pathway is also in bacteria.

Opinion: The Biological Function of Dreams | The Scientist Magazine® - Learning more about sleep…and REM sleep in particular.

The mystery of Siberia’s exploding craters - BBC Future – Gas emission craters. Studies have revealed a 3-5 year life cycle: a mound forms…rising several meters, the gas underneath explodes. They tend to form in areas where there is a thick layer of ice over permafrost…with some areas of unfrozen ground surrounded by permafrost…and very deep deposits of gas and oil. The big challenge has been to identify the source of the gas that builds up – because after the explosion it is already gone.

Forest fires, cars, power plants join list of risk factors for Alzheimer's disease: Airborne pollution implicated in amyloid plaques, UCSF-led study shows -- ScienceDaily and Air pollution spikes linked to lower test scores for Salt Lake County third graders -- ScienceDaily – Studies that show the impact of air pollution on humans….other reasons to step up the pace of the shift away from fossil fuels. Thinking positively – actions to address climate change tend to improve air quality.

Mistletoe: A Natural and Human History – A plant associated with the season! And there are other species of mistletoe from around the world.

Top 25 birds of the week: December 2020! - Wild Bird Revolution – Beautiful birds….at the end of the gleanings list for this week.

Climate change presents new challenges for the drinking water supply -- ScienceDaily – Studying the Rappbode Reservoir in Germany and applying models….helping to predict what happens with warmer temperatures and increased drought…and what tweaks in reservoir management can mitigate.

The Lanterna of Genoa, the oldest lighthouse in Europe – The current Lighthouse of Genoa was built in 1543. The article includes some pictures of the technology used in the lighthouse from the 19th and 20th centuries.

Pollution and pandemics: A dangerous mix: Research finds that as one goes, so goes the other -- to a point -- ScienceDaily – Studying the relationship between along term ambient particles with a diameter of 2.5 micrometers or less and the spread of COVID-19….using air quality data and COVID-19 case across the country. There is a correlation – more pollution….higher COVID-19 transmission. Also: "We found black carbon acts as a kind of catalyst. When there is soot present, PM2.5 has more of an acute effect on lung health, and therefore on R0." This is an example of how air quality degradation has adverse health consequences.

Leila Jeffreys' Elegant Bird Portraits Show Feathery "High Society" and Photographer Tim Flach Captures Emotive Portraits of Fascinating Birds – I prefer birds in the wild…but sometimes portraits show the bird with more detail…certainly with less distraction. These two series were quite different but full photogenic birds.

Two centuries of Monarch butterflies show evolution of wing length -- ScienceDaily – Looking through museum collections and island populations of Monarchs, the researchers discovered how migration selects for longer, larger forewings….non-migrants have smaller wings! And they have determined that the effect is due to genetics rather than the rearing environment.

Photography In The National Parks: Birdy, Birdy In The Sky – Almost half the gleanings this week are about birds. I think this is my favorite. National Parks…great places for photography and birds add some action in the scene!

Top 25 birds of the week: Coastal birds – Some I’ve seen (particularly the ones in this group that were photographed in New Jersey). Others are totally new – like the Great Stone-curlew found in coastal areas of southern Asia…striking head pattern…and eye.

Tens of thousands of 12,000-year-old rock paintings found in Columbia – Found in an area previously inaccessible to researchers due to Columbia’s 50-year civil war. Made with red ocher.

Vitamin D regulates calcium in intestine differently than previously thought – Still new discoveries to be made about how our bodies work…how complex and interconnected the chemistry is….a system of systems.

Newly Discovered Underground Rivers Could Be Potential Solution for Hawai’i’s Drought – The potential for water wells off the coast of islands…supplementing fresh water available on the land to support the population living there.

Iridescence - from archaeological glass to Art Nouveau – A little history of iridescent glass…how the effect is produced.

Photographer Captures Beauty of Starling Murmurations Across Europe – Awesome coordination of birds in flight. The starlings are not numerous enough in the US to create murmurations like this….but we did see flocks of tree swallows wintering in Florida that did.

New study reveals United States a top source of plastic pollution in coastal environments -- ScienceDaily and Plastic pollution is everywhere. Study reveals how it travels -- ScienceDaily – Plastic everywhere. We need to find a way to stop the waste.

Top 25 birds of the week: Plumage! - Wild Bird Revolution – Shots of color (I appreciated them more because it is a very cloudy day as I write this).

Into The Badlands Of El Morro and El Malpais National Monuments – Two places in New Mexico that I’ve visited several times…appreciated the pictures…reminder of how special these places are.

Which particulate air pollution poses the greatest health risk? -- ScienceDaily – Evidently the oxidative potential of particulate matter is key….wood combustion and metal emissions from brake and tire wear have higher oxidative potential, for example.

How to cut carbon out of your heating - BBC Future – A comparison of different types of heating…and other elements of carbon production related to heating where we live.

Wind & Solar Are Cheaper Than Everything, Lazard Reports – Great trend….now the market forces should push harder toward cleaner electrical generation.

The strange and surprising ways wild animals prepare for winter – The story starts out with bears but quickly moves on to animals not as well known for their winter preparations: moles, honey ants, chickadees, and snakes.

These Four-Foot Lizards Will Eat Anything—and They're Invading the Southeastern U.S. | Smart News | Smithsonian Magazine – The tegus, native to South America, and brought to the US as pets. They have roamed wild in southern Florida for a decade…and now are spotted around the southeastern US. It loves to eat eggs and thus is a threat to native species like quail, turkeys, alligators, and tortoises. The race is on to try to stop the invasion of this reptile.

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!

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’!

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!

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 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.

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).
