Congaree National Park to Remove Feral Hogs – There were feral hogs in the park when I visited in 2008!

Witness 1.8 billion years of tectonic plates dance across Earth’s surface in a new animation – I watched the video twice…the first just enjoying the overall moves. The second time I watched for how North America moved over time.

What Are the Best Policies for Reducing Carbon Emissions? - A systematic analysis of more than 1,500 climate policies from around the world found that only 63 were successful, reducing average emissions by 19 percent on average. Policies are more effective when implemented with a variety of other policies, instead of alone. In the U.K., banning coal-fired power plants worked when it was combined with tax or price incentives. The same was true for banning combustion engine cars in Norway. The study also found that successful strategies differed between countries—in developed countries, carbon pricing was effective, while regulation was successful in developing countries.

How thyroid hormone fuels the drive to explore - Research in mice sheds light on how thyroid hormone alters wiring in the brain. Findings reveal that thyroid hormone syncs up the brain and body to drive exploratory behavior. Too little thyroid hormone slows down metabolism and can result in symptoms of depression, while too much speeds up metabolism and can lead to symptoms of mania. The receptor for thyroid hormone is expressed by cells throughout the entire brain, including in areas of the cortex responsible for high-level cognition like planning and decision-making.

Cutthroats and Cottonwoods: Protecting the South Fork of the Snake - The South Fork contains the largest cottonwood gallery in the West. In the fall, the leaves on the tall-timbered giants lining the banks bounce in the breeze like gold coins exploding from the pot at rainbow’s end. Native Yellowstone cutthroat trout are in the South Fork. Most of the cutthroats spawn in tributaries contributing to the South Fork but they are found throughout and the farther you float, the bigger they get…. a river that is as it should be. Consistently wild.

Nutrition and healthy aging: The role of protein quality in combatting muscle loss - Aging may reduce our ability to digest, absorb and utilize the nutrients in food. It is important to consider increasing the amount and improving the quality of protein (probably higher than what is currently recommended for the general population) we consume. For example – research showed that consuming higher-quality (whey and pea) protein supplements at breakfast and lunch increased muscle-building in older adults by almost 10 per cent. However, collagen protein — a supplement heavily marketed towards older adults — did nothing to bolster muscle-building in older adults.

Flash Flood Roars Through Frijoles Canyon at Bandelier National Monument – One of my favorite places in New Mexico……hope I can visit again sometime when it isn’t flooded!

Cooler Communities for All - Four key design strategies to reduce urban temperatures:

  • Increase tree percentage in parks and green spaces

  • Provide shade

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

This Massive Egyptian Observatory Is Unlocking Celestial Secrets of an Ancient Culture - Archaeologists in Egypt have just uncovered a truly stellar find—a sixth century B.C.E. astronomical observatory in the ancient city of Kafr El-Sheikh. The observatory, made from mud bricks, is the largest and oldest of its kind in the region, spanning nearly 10,000 square feet. It was in ancient Egypt that the 365-day calendar was born, and the 24-hour day. They completely mapped the night sky, and had their own constellations and zodiac, some signs of which are still recognized today.

Looting of the Sudan National Museum – more is at stake than priceless ancient treasures - It was founded in 1959, ahead of the construction of the Aswan High Dam. A Unesco-led salvage campaign was launched in 1960 to protect and preserve the ancient monuments that would be flooded by the dam, which would alter the landscape of the Nubian region. The reported loss of parts of this collection represents a profound and multi-layered tragedy for future generations.

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

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

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

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

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

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

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

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

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

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

Top 25 birds of the week: #Spectacular - Wild Bird Revolution and Top 25 birds of the week: #August - Wild Bird Revolution – A double dose of bird pictures for this week!

A New Look at Ancient Nubia - Archaeology Magazine – South of Egypt….evidence of sophisticated culture centuries before the pharaohs extended their rule to the area.

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

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

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

Activities Discovered for Some Inactive Drug Ingredients | The Scientist Magazine® - There is more than the drug in the capsule….and it’s hard to know how many ‘side effects’ to drugs are actually a reaction to something that was supposed to be inert – but isn’t for everyone.

The Weird, Wondrous and Vulnerable American Horseshoe Crab – Cool Green Science – Blue bloods…and ancient…. Can they survive their interaction with humans?

Forty percent of dementia cases could be prevented or delayed by targeting 12 risk factors throughout life -- ScienceDaily – There 9 risk factors identified in 2017 (less education in early life; mid-life hearing loss/hypertension/obesity; later life smoking/depression/social isolation/physical inactivity/diabetes) and now there are 3 being added: excessive alcohol intake, head injury in mid-life, and air pollution in later life.

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

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

Unique Activities for Yesterday:

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