Gleanings of the Week Ending December 25, 2021

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

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

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

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

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

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

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

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

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

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

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

Gleanings of the Week Ending December 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.

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!

Gleanings of the Week Ending December 12, 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.

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.

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!

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!

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.

Ancient Artisans in Arabia, the Americas Invented Same Technology Independently | Smart News | Smithsonian Magazine – Stone fluting… and the fluting is not the same so it may have had a different purpose.

Baby boomers show concerning decline in cognitive functioning: Trend reverses progress over several generations, study finds -- ScienceDaily – The impact of modern life in the long term?

Ramesses II Statue Unearthed in Egypt - Archaeology Magazine – Multiple statues have been found…made of black and pink granite.

Top 25 birds of the week: #Waterbirds – Beautiful birds…not as many from North America as I expected.

Stone Sculptures of ‘Chronicles of Narnia’ Characters to Adorn Medieval Church – Replacing weathered carvings. There are 14 limestone carvings that will be displayed at ground level for visitors to see before being installed on the church’s exterior.

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.

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.

Earth at Night – This is an eBook from NASA that was last updated in December 2019….lots of pictures of the earth at night, analysis, and the technology behind the images.

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

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.

Scientists Use Agricultural Waste to Develop New Road Deicer - Yale E360 – Grape skins and other agricultural wastes rather than sodium chloride.

Poor Potato Crops Could Lead to a North American French Fry Shortage | Smart News | Smithsonian – Not a good year for potatoes in the US and Canada evidently. I wonder if prices will go up.

Hydration may affect cognitive function in some older adults -- ScienceDaily – Evidently overhydration has an impact on cognitive function as well…so it is important for older people to understand symptoms of both and actively manage their hydration.

Could Migraine Pain Relief Be Found In The Color Green? : Shots - Health News : NPR – Interesting research. Do green glasses help as much as the green LED light?

How everyday products are supercharging landfill gas, and what that means -- ScienceDaily – Some basic research that could be applied to getting more energy from our landfills.

U.S. States Have Eliminated Thousands of Environmental Protection Jobs Since 2008 - Yale E360 – “Neither EPA nor states have the funding they need to meet their responsibilities under the Clean Air Act, Clean Water Act, and other laws that protect the public’s health and our environment from dangerous pollution.” Not good.

How hacking the human heart could replace pill popping - BBC Future – Pacemakers are primitive compared to the devices that are being worked on now. The future implants will adjust to the situation…reading and writing to the nervous system to treat such things as diabetes, bladder control and chronic pain (and heart issues). Maybe they will address the root cause of some chronic diseases rather than just the symptoms.

Colouring Europe at Work: download our industrial heritage colouring book | Europeana Blog – Learn some history while your color.

IBM Changes the Energy Storage Game With Cobalt-Free Battery – Lots of research in the battery arena these days. This one caught my eye since I spent some of my career working for IBM. Maybe these will be part of the next-gen technology for batteries.

Tiny shells reveal waters off California are acidifying twice as fast as the global ocean -- ScienceDaily – Looking at shells of foraminifera in sediments provides a vertical record of ocean acidity.

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.

Infographic: How Air Pollution Could Affect the Brain | The Scientist Magazine® - A quick and disturbing summary. The evidence of harm: particles like those produced by vehicle engines found in frontal cortex (postmortem), reduced volumes of white matter, slowed development of children, inflammation related damage to brain cells, and higher accumulation of Alzheimer-associated proteins.

Happier Babies Have an Edge - Scientific American Blog Network – The more children experience happy emotions, the more time they spend building skills and relationships that help them in the future.

900 Pythons Removed from South Florida – That’s a lot of snakes. Kudos to the Python Action Team. There are other organizations (government and non-profits) working on this too. I wish the article would have included information about what they do with the snakes after they are captured. Presumable they are killed.

Study: 95 percent of baby food contains traces of toxic metals - UPI.com – Not good. The full report referred to in the article is available here. I wonder if pediatricians are changing their recommendation when it comes to some foods (like rice cereal for babies).

Newly discovered virus infects bald eagles across America -- ScienceDaily – Over 1/3 of America’s Bald Eagles are infected…and it might be causing a fatal disease – Wisconsin River Eagle Syndrome.

BBC - Future - What life might be like in alien oceans – Lots of possibilities. It will be interesting to get some probes (submersibles, etc.) out to the moons of other planets in our solar system that have alien oceans…maybe life.

From quills to typewriters: how the industrial revolution changed our writing culture | Europeana Blog – A little history lesson.

National Science Board highlights Skilled Technical Workforce shortage in new report - The Bridge: Connecting Science and Policy - AGU Blogosphere – “Without immediate action, the US risks falling behind other nations that are making significant investments in their Science and Engineering workforce and the Science and Technology enterprise.”  The whole report can be found here.

The Platypus Is Weirder Than You Ever Imagined – Cool Green Science – They don’t have a stomach, their venom can help treat diabetes, their milk can help fight antibiotic resistance….the list goes on.

Photography in The National Parks: Your Armchair Photography Guide To Olympic National Park, Part 2 – The Forests – National Parks….always a great destination for nature photography.
