Gleanings of the Week Ending December 24, 2022

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.

H5N1 Bird Flu Detections across the United States (Wild Birds) – A map of US counties where bird flu has been detected in wild birds as reported by the US Department of Agriculture.  It would be great if data could come from the National Wildlife Refuges (reporting through the US Department of the Interior) since they often have concentrations of wildlife and staff that would be monitoring the flocks. I know that there were instances of bird flu – primarily in snow geese - that the Bosque del Apache NWR staff were reacting to when we were there the November before COVID-19 curtailed our travel.

Electric car sales drive toward cleaner air, longer lives – Another reason my next car will be an electric rather than a plug-in-hybrid that I have now. However – this should probably be seen as an offset to the negative impacts on public health that climate change will bring; the air could be cleaner, but it will also be warmer and more turbulent. I am becoming less certain that my lifespan will last into my 90s like it has for my parents.

Living the lava life on Mauna Loa – A satellite image from NASA’s Landsat 9. It shows how close one of the flows came to Hawaii Space Exploration Analog and Simulation (HI-SEAS) project habitat. Fortunately, the most recent mission there concluded in May 2022.

The Dead Sea is dying – The lowest exposed place on Earth…water level dropping 4 feet per year…salt formations and sinkholes.

Beyond cola: the strange flavors of soft drinks – Carbonated drinks were invented by Johann Jacob Schweppe in 1783. They were sold in glass bottles and that were recirculated. Regional delicacies. Everything changed with the advent of plastic bottles in the 1970s. Moxie, state beverage of Maine, continued independently for a long time – bought by Coca-Cola in 2018. Soft drinks had a heyday in the years of Prohibition. Follow the link for the whole article, more soft drink history.

Construction of the world’s largest radio telescope begins – Square Kilometer Array (SKA) – one in Australia and one in South Africa. Construction will be completed by the end of the decade, but observations will begin in 2024.

Flameproofing lithium-ion batteries with salt – Finally….hope this solves the fire problem with lithium-ion batteries and, if so, moves into new battery manufacturing quickly.

The 120-year search for the purpose of T. Rex’s arms – A little history of T. Rex finds…and the various ideas about why the animal had such puny arms.

A new weapon against antibiotic-resistant bacteria – Work to find a new treatment for Klebsiella pneumoniae infections that are resistant to common antibiotics with some strains fatal for 40-50% of infected people. A new strategy: weakening bacteria with an existing drug previously used to treat herpes that alters its surface layer to make it easier for the immune system to kill the bacteria. The idea works in the research model…effectiveness in human beings yet to be confirmed.

The science of why hawks are one of nature’s deadliest hunters – Birds and bats….The birds steer toward a fixed point in the swarm instead of singling out a bat. It’s a good strategy against a gathering of prey!

Gleanings of the Week Ending August 14, 2021

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

How your phone battery creates striking alien landscapes – Lithium….needed for batteries that are needed for so many things (not just phone batteries).

Why do house finches love your hanging plants? – These birds are frequent visitors to our feeder. Based on the crowd we are seeing now – they’ve had a very successful breeding season…lots of young birds.

Ultraprocessed foods now comprise 2/3 of calories in children and teen diets – This article prompted me to look at what ultraprocessed foods I am eating…and making some changes. I am keeping the 1st breakfast that includes 90 calories of dark chocolate…but all the other ultraprocessed foods are going to become occasional or rare in my diet.

Tracking the Restoration of the River of Grass – An interview with Eric Eikenberg, President of the Everglades Foundation. There is a lot of work coming to fruition this decade in restoration of the Everglades…some positive news from Florida. It was an encouraging article but after reading the whole thing, it still seems to me that climate change will be a continuing disaster for Florida.

Red Tide Rages Along Florida’s Gulf Coast – On a more pessimistic note about the environment in Florida right now…

Top 25 birds of the week: August 2021 – Birds….so many different kinds to see.

Crawling with crickets: the insect swarm in the western US – Mormon Crickets (really katydids) have population crescendos in 3 of every 10 years in the west. The occurrences are patchy but damaging for some crops.

Music in the American Wild – I watched the Missouri Music at 200 webinar this week and am now looking at more of the concert videos from the ensemble. I’ll post the “Missouri Music at 200” webinar video address (when it is available on YouTube). Of course – live performances would be even better. I enjoyed the Hawaii 2020 project videos already…lots of good views of the island (particularly birds and volcanos!).

The ancient Persian way to keep cool – We’ve had quite a few heat advisory days recently…will probably have an increasing number every summer. The world will need to implement the most efficient strategies available to keep people cool.

Camera Trapping As Mainstream Nature Activity – Little cameras in the wild…they are probably less obtrusive than a human being in the place all the time…but not totally benign in every place.

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.

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.

Older forests resist change, climate change, that is -- ScienceDaily  - A study from the University of Vermont. But there are a lot of other changes in the forest too – the advent of non-native diseases like emerald ash borer and the explosion of deer populations so that there is a lot less understory in the forest (and few young trees). Is the net still that old forests resist change more effectively than younger ones?

Top 25 Wild Bird Photographs of the Week: June – National Geographic Society Newsroom – The always beautiful series of bird pictures.

Expanding the temperature range of lithium-ion batteries ScienceDaily – I’ve noticed the battery in my Prius Prime does not last for as many miles in the winter as it does in the summer. It’s one of the issues I want improved before I buy my next EV.

Chattanooga Becomes First U.S. Airport to Run Entirely on Solar – YaleEnvironment360 – Congrats to Chattanooga on this milestone. Evidently the first airport to do it was Cochin International in Kerala, India which went 100% solar powered in 2015. I’ve noticed a lot of US airports have fields of solar arrays…but maybe they haven’t also installed batteries to make the airport 100% solar powered.

You Can Now Tour the Tunnels Beneath Rome’s Baths of Caracalla – Smithsonian – A little Roman history linked to a place where tons of wood were burned per day to keep the fires going so that the caldarium would have hot water…where 18.5 gallons of water per second were consumed…copper tanks and lead pipes.

Timed release of turmeric stops cancer cell growth – ScienceDaily – Part of the search for gentler treatments for children with osteosarcoma.

A Tale of Contrasting Rift Valley Lakes – NASA Earth Observatory – Lake Tanganyika and Lake Rukwa as viewed from NASA’s Aqua satellite.  Deep and shallow. Salty and fresh. Brown and Blue.

Alibates Flint Quarries National Monument: Holding History in Your Hand – National Parks Traveler – I had to look up where Alibates Flint Quarries National Monument is located. It’s in the panhandle of Texas, north of Amarillo. I might go someday…on the way to somewhere else. The route would probably pass through the small western Oklahoma town where I was born.

Grand Canyon will soon be a dark sky park – Smithsonian – The park service has retrofitted lights to make it happen. This could be a good reason to camp in this national park!

What does the dust in your home mean for your health? – The Conversation – Thought provoking post. About one third of the ‘dust’ is created inside by ourselves and our pets, food debris, fibers from carpet/fabrics, particles from cooking plus chemicals like flame retardants. Are they toxic? There is ongoing research. Re outdoor sources – lead is the one of most concern.
