6 Things You Should Never Wear on a Flight – Most of the suggestions are good for road trips as well.

What Your Last Name Says About Your History – Interesting…a different perspective on names.

Photos of the Week – December 6, 2024 – Winter sunrise/sunset beauty on the prairie.

German Archaeologists Discovered the Iconic Bust of Nefertiti in an Ancient Egyptian Sculptor’s Studio – One of the most famous of ancient Egyptian artifacts…’ownership’ has been questioned from the beginning.

Lifesaver for wild bees: The importance of quarries – Research done in Germany, but Missouri has considerable limestone…perhaps we should be striving to keep quarries open rather than overgrown with woody plants. Many wild bees in Germany and in Missouri nest in the ground and often need open, sunny areas to do so.

Archaeologists discover key tool that helped early Americans survive the ice age - Tiny artifacts unearthed at a Wyoming site where a mammoth was butchered 13,000 years ago are revealing intriguing details about how the earliest Americans survived the last ice age. Archaeologists found 32 needle fragments made from animal bone buried almost 15 feet (nearly 5 meters). Analyzing the bone collagen of the needles revealed they were created from the bones of red foxes, bobcats, mountain lions, lynx, the now-extinct American cheetah, and hares or rabbits!

Here Are 2024’s Best Northern Lights Photographs - From a purple and green sky in Canada's Banff National Park to an unexpected, fiery orange appearance in Namibia, this year's auroras took us by surprise. While called the Northern Lights Photographer of the Year, there are plenty of Southern Lights represented in this year's collection too.

The Arctic Could Have Its First ‘Ice-Free’ Day by as Early as 2027 - The first summer on record in which practically all the sea ice in the Arctic melts could occur much earlier than previously expected. In a new study, scientists warn that the ever-increasing greenhouse emissions may bring us closer to an ice-free Arctic by the end of the decade.

Water Infrastructure, Disasters, Water Scarcity & Security, Potable Water, & Conflict – A post about what happened to Ashville, NC. Water-related disasters currently make up over 90% of all disasters on Earth, with record-breaking floods and droughts making headlines around the world. Over the past ten years, the number of fatalities from these catastrophes has doubled. Climate change, warming surface water temperatures, and more aggressive hurricanes making their way up to some of the planet’s oldest mountains in North Carolina have all contributed to a growing awareness that rising temperatures have disrupted the entire water infrastructure of the Appalachians.

Meet the Mysterious Woman Who Shaped MoMA – A biographical post about Lillie P. Bliss and the creation of the Museum of Modern Art as an exhibition focused on her opens.

Drought Expands Across the U.S. – We are finally getting some rain…but we are in the ‘extreme drought’ area of southwestern Missouri; it is going to take a lot to get back to ‘normal.’ On October 29, abnormal dryness and drought affected over 78 percent of the American population—the highest percentage in the U.S. Drought Monitor’s 25-year-long record.

Cholera, Zika and West Nile: The deadly diseases that sweep in after hurricanes – Damage to infrastructure has been the big focus of reporting in the US, but diseases are ramping up.

• Florida health authorities released a warning in early October of a likely spike in Vibrio vulnificus infections, urging residents to avoid wading in floodwaters.  Vibrio vulnificus is a bacteria which can cause the breakdown of skin and soft tissue, sometimes leading to amputations.

• West Nile cases rose in Louisiana and Mississippi following Hurricane Katrina.

• Studies found that flooding in Louisiana following hurricanes Rita and Katrina led to an increase in the airborne fungi Penicillium and Aspergillus, which can cause allergies, respiratory infections and pneumonia.

• Research into the aftermath of hurricanes Maria, Irma and Michael, shows that a significant number of people in Florida developed new chronic health conditions such as asthma and allergies in the six months following the disasters.

Satellite Imagery Shows Breadth of Flooding in Spain - Valencia saw a year’s worth of rainfall in just eight hours, with floods destroying buildings, disrupting trains, and leaving more than 100,000 homes without power.

What animal societies can teach us about aging - Humans are not the only animals to change our social behavior as we age. Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off.

The world’s oldest tree? Genetic analysis traces evolution of iconic Pando forest - By sequencing hundreds of samples from the tree, researchers confirmed that Pando, a quaking aspen tree (Populus tremuloides) in Utah, is between 16,000 and 80,000 years old. Pando consists of some 47,000 stems that cover an area of 42.6 hectares in Utah’s Fishlake National Forest. Because of the way the plant reproduces, this collection of aspens is technically all one tree, supported by a single, vast root system. Pando is triploid, meaning that its cells contain three copies of each chromosome, rather than two. As a result, Pando cannot reproduce sexually and mix its DNA with that of other trees, and instead creates clones of itself.

Have we found all the major Maya cities? Not even close – Using lidar to survey 50 square miles revealed evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

Stunning Shortlisted Photos From the 2024 Close-Up Photographer of the Year Contest – My favorite was “Chicory” for the color…and that I knew what it was!

Low-level lead poisoning is still pervasive in the US and globally - Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children. Factors such as menopause and hyperthyroidism release lead sequestered in the skeleton, which causes a spike in blood lead concentrations. The solution to protecting people from lead poisoning is to identify and eliminate environmental sources of lead: eliminating lead acid batteries, replacing lead service lines, banning leaded aviation fuel, reducing lead in foods, abating lead paint in older housing, and further reducing lead-contaminated soil and other legacy sources.

Ghost Forests Creep Into North Carolina - Large swaths of cypress and pine forests along the southeast Atlantic coast have died, shed their bark, and become pale, leafless snags that line the waterways like gravestones. In the period before winds topple the snags over and shrubs cover them up, researchers call the eerie ecosystems “ghost forests.” One place that is it happening is Alligator River National Wildlife Refuge…and I realized I have been there! We visited in April of 2015. It was the first place I saw river otters and two vultures (different species) sharing a meal. There probably were bald cypress dying in 2015, but it is even more evident now.

Trees cool better than reflective roofs in vulnerable Houston neighborhoods - Heat islands occur in cities where structures such as buildings and roads absorb the sun's heat more than natural landscapes such as trees and grass. The researchers considered three different heat island mitigation strategies: painting roofs white to increase solar reflectance; planting vegetation on roofs to increase evaporation through the plants; and planting more trees, which increases evaporation and provides shade.

Pair of Resting Cuckoo Bees Wins the Royal Entomological Society’s Insect Photo Competition – Wonderful images of insects. My favorite is the Wavy-lined Emerald Moth (“A forest gem”).

The Role of Commons in Our Future Resilience - The climate and biodiversity crises will make collective land and water resources the source of future cooperation and conflict. If our commons aren’t governed well, we can have a “future of global violence.” Balancing the needs of local communities and conservation and restoration will require strong relationships between governments and the people who depend on commons for their livelihoods and culture.

Study shows how liver damage from stress and aging might be reversible – The study showed that aging exacerbates non-alcoholic liver disease by creating ferroptic stress, and by reducing this impact, we can reverse the damage.

Extreme Heat’s Far-Reaching Impacts - In addition to the expected impacts — dehydration, heat exhaustion, and heat stroke — heat can also endanger pregnant women, impact sleep patterns, and increase irritability, depression, and suicide rates. Heat is also associated with higher rates of violence and aggression, including intimate partner violence and gun violence.

The chemistry of Polaroid photography – The technology behind taking a picture and printing it instantly.

Cooling Solutions for Cities That Lower Surface & Air Temperatures – Some productive and appealing ways to cool urban heat centers.

Funny Early Entries of the 2024 Comedy Wildlife Photo Awards – Images that will make you smile!

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems - Some 40 million people currently live in areas served by combined sewer systems (in places like Philadelphia, New York, and Boston) that are at increasing risk of being inundated by untreated sewage during floods.

Ancient Egyptian Scribes Were Worked to the Bone - Scribes sat in cross-legged or kneeling positions for long periods of time, hunched over paper and ink. Such activity was bound to overload the jaw, neck and shoulder regions. 30 skeletons of scribes from a northern Egyptian cemetery were examined. Much of the damage was found on the skeleton’s right sides, with the right knee being an especially common point of osteoarthritis, possibly because scribes repeatedly squatted on their right legs, the researchers theorize. And ancient Egyptian iconography commonly depicts scribes writing with their right hands. The posture impacted scribes’ backs.

Pronghorn Place: Preserve Protects Wildlife Migration Route – About the Flat Ranch Preserve on the outskirts of Yellowstone National Park…what has been learned about the Pronghorns migrating through. It reminded me of the pronghorns I saw at Sevilleta National Wildlife Refuge (New Mexico) in 2018.
