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.

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

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.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

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.

Why the world feels so unstable right now – Intermittent instability of nonlinear systems of nature and global society –weather and climate, the economy, a pandemic, a war. We attempt to model nonlinear systems to predict these intermittent instabilities…but it is hard. Right now there seem to be significant nonlinear systems interacting: weather/climate + diseases (COVID-19 and bird flu (US)) + inflation + Russia’s invasion of Ukraine.

Completing The Electrical Circuit at Kilauea in Hawai'i Volcanoes National Park – The technique to get a detailed ‘CAT scan’ of the volcano…..mapping locations of subsurface magma in 3D.

Ex-cell-ent Clouds off Chile’s Coast – Open and closed-cell marine stratocumulus clouds photographed by Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. Learning more about these clouds….contributing to better weather prediction and improving the accuracy of climate models.

The Surprising Substances Ancient Egyptians Used to Mummify the Dead – Evidently some of the substances the embalmers were using came from Southeast Asia. Perhaps embalming instigated early global trade.

Algae robots transport antibiotics to infected tissues (infographic) – Researchers inserted the modified algae into mouse windpipes…they spread into the lung tissue and killed pathogenic bacteria!

Hundreds of Frank Lloyd Wright’s Designs were never built. Here’s what they might have looked like. – Computer generated models from David Romero.

5 expert tips to protect yourself from online misinformation – We all need tools to help us distinguish information from misinformation.

Montessori: The world’s most influential school? – I sought out a Montessori pre-K and K for my daughter about 30 years ago…and it fit her needs. I have no way of analyzing how closely the school adhered to classical Montessori ideals.

An action plan to prevent Alzheimer’s disease – Defining what 2nd generation memory clinics should include.

Gallup: Fewer than half of Americans believe US healthcare is good enough – Not surprising really – it’s expensive and we are all getting more skeptical that the system is as effective as it should be for what it costs. Evidently the people in my age group (over 55) were generally more satisfied with their health care than other age groups; people old enough to qualify for Medicare may not be as anxious about costs but I was surprised that I am in the minority in thinking US healthcare is ‘subpar’ rather than ‘excellent’ or ‘good’ based on the effectiveness issue and the structure of the system overall.

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.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory.  A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.

Top 25 Wild Bird Photographs of the Week: Seabirds – Starting with the birds this week. I’m thinking about the Delmarva birding sessions later this month…they’ll be sea birds and more to see.

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

A little prairie can rescue honey bees from famine on the farm -- ScienceDaily – Food crops can provide good food for honey bees…but maybe not for the whole season.

Adult Humans Can Regenerate Cartilage: Study | The Scientist Magazine® - microRNA may have potential in human regeneration of tissue.

Agar Art Contest 2019: See this year’s winners – Art made with live bacteria.

Infrared Reveals Egyptian Mummies' Hidden Tattoos | Smart News | Smithsonian – 7 mummies – 3,000 years old. All the mummies with tattoos at the site were women.

Gabapentin: A Risky Answer to the Opioid Epidemic - The Atlantic Gabapentin has become the 10th most-commonly-prescribed medication in the US. It is viewed as a safer alternative to opioids for chronic pain….but it is problematic in combination with other sedating medication and it doesn’t work as well as hoped….particularly for back pain. It appears that looking for a quick fix for chronic pain is – again – not working as advertised.

Photography In The National Parks: My Favorite Spots For Great Photos – From Arches, Bryce Canyon, Big Bend, Acadia, and Padre Island.

Scientists Don't Know Why Freshwater Mussels Are Dying Across North America | Smart News | Smithsonian – It’s not just in one place….and may have multiple causes. But this just highlights that some mussel species that have already gone extinct…and our rivers are very different than their ‘natural’ state.
