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.

Four key questions on the new wave of anti-obesity drugs – Several of the drugs were originally developed to treat type 2 diabetes but now are popular weight loss drugs.

Sweet smell of success: Simple fragrance method produces major memory boost – A study done by the University of California, Irvine on older adults…participants reaped a 226% increase in cognitive capacity compared to the control group. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

How the US is fighting back against deadly floods – Identifying flood plains…not building back in them after a flood.

Old-Growth Trees, Some Dating To 17th Century, Protected at New River Gorge – The Burnwood Loop – where I want to hike first in the New River Gorge National Park and Preserve!

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

New Thermal Activity on Geyser Hill in Yellowstone National Park – Short video from the Yellowstone Volcano Observatory.

‘Perfectly Preserved’ Glassware Recovered From 2,000-Year-Old Shipwreck – The shipwreck was located 1,148 feet below the surface in waters between Italy and France. Two remotely operated vehicles (ROV) were used to scan the site and recover artifacts.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.

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.

Cold is beneficial for healthy aging, at least in animals – Research with nematodes and cultivated human cells. Both carried genes for ALS and Huntington’s disease. Cold actively removed protein clumps…preventing protein aggregation that is pathological for those diseases. The protease activator that caused the change was discovered…and the impact of temperature explored. Interestingly – “human body temperature has steadily declined by 0.03 degrees Celsius per decade since the Industrial Revolution, suggesting a possible link to the progressive increase in human life expectancy over the last 160 years.”

See Colorful Paintings of the Zodiac Signs from an Ancient Egyptian Temple – Ceiling paintings in a Ptolemaic temple…suggesting Greeks brought the zodiac tradition to Egypt.

 Nearly 1,000 Acres Added to New River Gorge National Park and Preserve – The acres are in the Preserve part of the park. I have visited the park only once…passing through on one of my many trips between Maryland and Missouri. There is a lot to explore there!

Vehicle Exhaust Filters Do Not Remove “Ultrafine” Pollution – Aargh! No wonder there are so many yellow and red air quality days in our cities caused by particulates.

What it really takes for Asia to get to net zero – Home to 5 of the 10 largest emitters: China, India, Indonesia, Japan, and South Korea. An article posted ahead of the BBC’s Sustainability Summit in Singapore. "The perception of higher cost for sustainability practices remains," says An (chief sustainability officer of City Developments Limited in Singapore). "But companies are starting to wake up to the fact that achieving climate goals is an "investment, not a cost."

Thread-like pumps can be woven into clothes – My first thought was maybe these will be commonplace in clothes – enabling us to work outdoors even on very hot days.

Sabertooth cat skull newly discovered in Iowa reveals details about this Ice Age predator – Almost as iconic as dinosaurs when it comes to childhood curiosity about extinct animals. One piece of trivia about modern cats: 40% of lion skulls in a study had survived head trauma to hunt another day. One of the ‘sabers’ of the Iowa Sabertooth was broken not that long before it died…might have even caused its death. Prey fights back…the predator does not always ‘win.’

Europe's unique trials in food 'social security' – Two projects: Montpellier, France and Brussels, Belgium. Run by collectives. The idea that quality, nutritious and organic food should be accessible to everyone.  Each citizen receives a monthly allowance enabling them to buy food meeting certain environmental and ethical criteria. The trials are running for 12 months. The big challenge is changing the way society thinks about food.

The Beauty of Bugs – The picture at the beginning of the article jogged my memory – of the necklace made from insect exoskeletons I saw at the Edge of Cedars State Park Museum when I visited Utah in 2013! I posted about it and took a picture back then…and am pleased to learn more about it and the possible implication it might have re the Basketmaker II culture.

Scientists discover a way Earth’s atmosphere cleans itself – It’s surprising that we don’t know more about how the Earth’s atmosphere works!

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

Photography In the National Parks: My 10 Favorite Shots From 2021 – I only went to one national park in 2021: New River Gorge (in West Virginia). There are so many beautiful National Parks to see…and they’re worth seeing again and again.

Big Gulp: Blue Catfish Eat Wood Duck – We’ve seen fishermen catch blue catfish at the base of Conowingo Dam (we’re there for the bald eagles). They are huge…sorry to learn that they eat ducks.

Top 25 birds of the week: Raptors! – How many of these live in your area of the world?

Air Pollution Makes It Harder for Bees to Sniff Out Flowers – Not just a problem for bees…also moths, hoverflies and butterflies are having a harder time. This results in a 14-31% reduction in pollination among plants exposed to polluted air.

Ocean microplastic pollution may be greater than estimated – Not a good trend…and this form of pollution that is new enough that the full impact is still being discovered.

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats – Another way the world is becoming less resilient at a time when climate change is pushing all life to use all the resilience available.

Large Permian Basin Methane Leaks Are Causing As Much Climate Pollution as 500,000 Cars – It’s frustrating that the oil industry has not been a better steward of resources they are extracting for energy. The methane leaks are a waste of the effort put into extraction….and bad for the planet too.

Dinosaur food and Hiroshima bomb survivors: maidenhair trees are ‘living fossils’ and your new favorite plant – Learn more about the ginkgo tree! There is one along my walking route in my neighborhood and others I find in local gardens and parks near where I live. They are so different from other trees…worth noticing.

North Sea Fossil Fuel Companies Plan to Invest More in Wind than Oil Drilling – Hurray! Maybe other companies around the world begin to do this too….a strategic move for Shell, Total and BP.

Antimicrobial resistance now a leading cause of death worldwide, study finds – This challenge will increase over time…if we don’t take action to slow the development of resistance and develop new antimicrobial techniques (maybe we need more strategies than simply trying to develop new antibiotics).

Springfield MO to Home

/

I said goodbye to my daughter in Springfield MO and headed out at dawn. Her street was full of fall color – more on the ground than in the trees.

I had decided to take a different route east from Springfield to avoid the traffic on I44 toward St. Louis. I drove on US 60 toward Poplar Bluff MO. There were a few stop lights, but the traffic was light and it was a sunny day. I made stops at a grocery store, a fast-food place and then gas station. None were very photogenic although the Dino Mart name caught my attention.

While I was driving there was lots of beautiful scenery. There were signs for Missouri state parks and trails all along way. As I continued toward Paducah KY the road became two lanes (one in each direction) with no shoulders (often on the top of a levee) and there were two long bridges over the Mississippi and Ohio Rivers. It was the type of road that begs for scenic overlooks…but it didn’t have them!

In Kentucky I travelled the Western Kentucky and Blue Grass Parkways to Lexington KY. There was one rest stop with some fall foliage along the way and I managed a picture of some fall color across the road.

I was relieved that my route from Lexington the next morning was on an interstate with frequent rest stops – and I started out with a full tank of gas so I would only need to stop once for gas during the day. The foliage along the route in eastern Kentucky was probably the best of trip even though many trees had already lost their leaves.

I set my destination to the New River Gorge National Park visitor center just off I64 in West Virginia. It was a very scenic drive, but I realized when part of the route was toll road that I was off the route I had used previously through West Virginia. I walked around the outside of the visitor center enjoying the fall foliage; I didn’t have time to stay very long since I wanted to be home before dark.

At first, I thought my route would still take me up to I70 eventually…but it didn’t. I was on the heavily travelled I81 before I knew it and then was locked into taking I66 (lots of construction) toward Washington DC. Traffic was a little better on the Washington Beltway. And I made it home before dark even though I was exhausted from driving in heavy traffic at high speeds.

My husband claims our maple tree lost its leaves while I was driving…there were still a few at the base of the tree the next morning.

I noticed a black walnut tree near where I parked for a doctor’s appointment later in the day: no leaves…but nuts still attached like decorative balls!

It is good to be home again even though I missed the best of fall foliage there this year.

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

Top 25 birds of the week: Bird Interactions! - Wild Bird Revolution and Top 25 birds of the week: Raptors!  and Top 25 birds of the week: Feathers!  – A treat this week – 75 bird photographs – enjoy!

The unseen 'slow violence' that affects millions - BBC Future – The harms that happen so slowly that we don’t notice in the moment. It happens over months and years and decades (maybe even centuries). We notice as we use our ‘big data’ to see hot spots of ill-health, where the environmental degradation is at it’s worst, and populations that can’t seem to escape their dire situation. And the issue very quickly becomes – how does our culture respond to the awareness of that ‘slow violence.’

Carbon: Getting to net zero -- and even net negative -- is surprisingly feasible, and affordable -- ScienceDaily – A detailed model of the entire US energy and industrial system….showing how to achieve carbon neutrality by 2050…with particular emphasis on what needs to happen in the next 10 years.

The country rejecting throwaway culture - BBC Future – France has introduced an index of ‘repairability’ rating for appliances…hoping to increase the electronics repair rate to 60% within 5 years. I’m glad I opted to repair my clothes drier rather than replace it….although the repair (replacing of the failed heating element) produced some trash it was a lot less than the whole appliance! Things like phones and laptops and monitors are harder.

Carolina Wrens Will Nest in Just About Anything and Why Carolina Wrens Have Moved into Your Neighborhood – We had a Carolina Wren make a nest in a gas grill we hadn’t used in along time. It surprised me when I opened the lid and the bird – startled and then panicked – flew out onto the deck railing. There is usually a pair nesting somewhere around our yard; we see them when they come to the feeder and hear them even more frequently. The forest behind our house and the brush pile at the edge of the forest are good places for them.

Federal Funding Obtained to Replace Zion National Park's Shuttle Fleet – And they’ll be electric! What a great way to keep the air smelling like nature rather than combustion fumes!

Rare Yellow Penguin Photographed for the First Time | Smart News Science | Smithsonian Magazine – What an unusual looking bird! It’s a king penguin on South Georgia Island with leucism, a condition where melanin is only partially lost and some parts of the body retain color. In this case…the ability to produce the usual black pigment is missing.

New River Gorge is America's Newest National Park - News | Planetizen – This park is within ‘road trip’ distance from where we live….maybe a destination post-pandemic.

How we turned a golf course into a haven for rare newts, frogs and toads – Hopefully US golf courses are doing things like this too. I usually think of them as using a lot of chemicals and would not want to live near a golf course….but if they consciously made places for amphibians….it would mean that other creatures could survive in the space too. There is an Audubon International Certification program for golf courses but they don’t publish a list of course that are certified.

The Arctic Ocean might have been filled with freshwater during ice ages – Based on a geochemical study of sediments.
