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.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

• Embedding well-being into curricula for broader, more accessible adoption.

• Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

• Tailoring initiatives to the student body and university culture.

• Securing buy-in from faculty.

• Ensuring new offerings are accessible and don't create additional financial burden for students.

• Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance? – A diverse array of microorganisms were found in the hot waters of the Roman Baths. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

The Changing Nature of Wilderness - The U.S. government has begun to acknowledge the Indigenous history of ‘wilderness’ areas and, in some (very few) cases, restored land to native tribes or created co-management agreements.

Nearly 25% of land in Africa has been damaged – What’s to blame, and what can be done - The “big five” drivers of land degradation globally and in Africa are:

• biological invasions, where plant species have spread outside their indigenous area and disrupted the services provided by ecosystems

• climate change driven events, such as intense droughts and severe fires

• extractive activities, such as mining and over-harvesting

• habitat transformation or fragmentation, including deforestation and poor agricultural practices

• pollutants such as sulfur dioxide, and eutrophication – where algae and other plants take over plant life.

The Hunt: Genghis Khan’s Final Resting Place - His last wish was to be buried in secret, something his soldiers accomplished in two ways: by killing everyone they met enroute to the gravesite, and then trampling that site under the hoofs of their horses until no trace was left. Although tomb culture, inherited from the neighboring Chinese, was well-established by the time Genghis Khan was born, many were constructed underground, some at a depth of more than 65 feet. Most Mongolians today would prefer that Genghis Khan’s tomb stayed hidden. Not because discovering it would unleash an ancient curse—a superstition that was actually quite widespread in Soviet times—but simply out of respect for the historical figure’s dying wish.

Airplane noise exposure may increase risk of chronic disease - Research has shown that noise from airplanes and helicopters flying overhead are far more bothersome to people than noise from other modes of transportation, and a growing body of research suggests that aircraft noise is also contributing to negative health outcomes.

New fossils show what Australia’s giant prehistoric ‘thunder birds’ looked like – and offer clues about how they died out - While the birds had broad, short toes and hoof-like claws for moving across open ground between bodies of water, their partial reliance on freshwater and new plant growth would have become more difficult as ponds and lakes shrunk and disappeared.

Phoenix Heat Deaths Rose by 1,000 Percent in 10 Years - Relentless heat led to 645 deaths last year in Maricopa County, the most ever documented in Arizona’s biggest metropolitan area. Almost half of the victims last year were homeless — 290 people. Twenty died at bus stops, others were in tents, and an unrecorded number of people were found on the pavement, prone as if on a baking stone.

Warming Brings Early Bloom to Bulgarian Rose Fields – Bulgaria is a top producer of rose water and rose oil. To produce these goods, pickers must harvest the flowers early in the morning, when their petals are richest in oil. After a mild winter and warm spring, pickers in Bulgaria’s Rose Valley have headed to the fields around three weeks earlier than normal.

Shasta Lake Filles Up Again - After consecutive wet winters in Northern California, Shasta Lake filled up for the second year in a row, in time for summer 2024. The healthy cache of water in back-to-back years was a welcome turnaround from drought conditions and low lake levels in 2019–2022.

The chemistry of hydrangea colors – This works for the Asian hydrangeas….not the North American natives (oak leaf and wood hydrangeas).

Are there long-terms health risks to using Botox? - Botox is the most common cosmetic procedure performed worldwide, with nearly three million injections estimated to take place each year. It works by blocking signals from the nerves that control the facial muscles. The muscles relax, and fine lines and wrinkles disappear. Very little is known about the long-term health effects of taking Botox, as most clinical trials only follow up on patients for six months or so. However, some studies have found that long-lasting cosmetic use of botulinum toxin can trigger permanent changes in facial expression, with persons no longer able to flex their facial muscles.

How a Small Herd of Romanian Bison Is Locking Away Thousands of Tons of Carbon - European bison were reintroduced to the Țarcu Mountains, at the southern end of the Carpathian range, in 2014. Now numbering 170, the bison are reshaping the mountain landscape in ways that are helping clean up emissions: the Țarcu grasslands are capturing roughly 10 times as much carbon as they were before bison were reintroduced.

Preserving The Thermal Springs And Bathhouses Of Hot Springs, Arkansas – This post from National Parks Traveler came out while my daughter and I were in Hot Springs. I saw it after I got home.

How Can You Stop a Disease-Carrying Mosquito? – Hawaiian honeycreepers are dying of avian malaria spread by mosquitos. Now there is a project that is releasing male mosquitoes (they don’t bite and don’t spread diseases, females are the ones that bite/feed on blood) that causes breeding to fail – thus causing the mosquito population to crash. Even if this is successful, there is more to do for the birds to thrive: forest restoration, keeping weeds out, eliminating invasive pigs, some captive breeding of the birds.

Blood pressure drugs more than double bone-fracture risk in nursing home patients - The medications tend to impair balance, particularly when patients first stand up and temporarily experience low blood pressure that deprives the brain of oxygen. Interactions with other drugs and low baseline balance in many nursing home patients compound the problem. A combination of less medication and better support could significantly reduce the problem.

Hurricanes, heatwaves and rising seas: The impacts of record ocean heat - Every day since late March 2023, global ocean surface temperatures have set new records for the hottest temperature ever recorded on that date….and the repercussions are already beginning.

Fewer Than 100 Cigar Orchids Found In Big Cypress National Preserve - A months long search for rare cigar orchids in Big Cypress National Preserve in Florida has turned up 85 of the plants the state of Florida considers endangered. No plant had produced any fruit in the 2021 and 2022 seasons.

Lead Pipes Make Up Nearly One Tenth of US Water Service Lines - Improvements to the 1991 Lead and Copper Rule proposed in late 2023 could finally require water systems to provide accurate information and enforce the replacement of lead pipes. However, a proposed exemption would give cities like Chicago an extension, letting them take multiple decades to replace infrastructure.

Surprisingly vibrant color of 12-million-year-old snail shells – Polyenes (includes carotenoids) preserved almost unchanged…and found in fossils.

Asbestos: The strange past of the 'magic mineral' – Asbestos was woven into textiles fit for kings and used for party tricks. One 18th-Century philosopher even slept in a night-cap made from it. It was also used to make the funerary shrouds for monarchs; because it didn't burn, it helped to keep their ashes separated from the rest of the pyre. An account from Ancient Greece describes a golden lamp made for the goddess Athena, which could reportedly burn for a whole year without going out and had a wick made from "Carpathian flax" – thought to be another name for asbestos. In 1899, an English doctor recorded the first confirmed case of a death linked directly to the material – a 33-year-old textile worker who had developed fibrosis of the lungs. In the UK, all asbestos was banned in 1999, but much of the asbestos added before this date remains in place – as buildings degrade, it is posing a significant health risk.

Rise of Peru’s Divine Lords – Hilltop sites in the Andes…early examples of divine lordship - a form of leadership that would endure in Peru for more than 1,000 years.

Amid Record Drop in Fossil Power, Europe Sees Wind Overtake Natural Gas - The E.U. power sector is undergoing a monumental shift - fossil fuels are playing a smaller role than ever as a system with wind and solar as its backbone comes into view. Coal generation fell by 26 percent, while gas generation fell by 15 percent.

Student Design Competition: Integrating Solar and Agriculture - Some 2.8 gigawatts of agrivoltaics exist across the U.S. Many combine solar energy with pollinator habitat and sheep grazing. The National Renewable Energy Laboratory (NREL) is looking for new design proposals from graduate and undergraduate landscape architecture students to push the agrivoltaics envelope!

The Moon Is Shrinking, Causing Moonquakes at a Potential NASA Landing Site - Researchers examined data on moonquakes detected by lunar seismometers, which have been on the moon since Apollo program astronauts left them there more than 50 years ago. They also used mapping data from NASA’s Lunar Reconnaissance Orbiter to identify the telltale creases on the moon. Through modeling, they linked these faults to seismic activity.

Texas Reservoirs Reach Dangerous Lows - In Corpus Christi, on the south Texas coast, authorities last month stopped releasing water aimed at maintaining minimum viable ecology in the coastal wetlands, even as oil refineries and chemical plants remain exempt from water use restrictions during drought. On the lower Texas coast, the Rio Grande has not been flowing consistently, and Colorado River water releases have been minimal as that river faces shortages farther upstream.

Extreme Birding: Gull Watching at the Landfill - You can find gulls around North America (and many parts of the world), including in interior states. At least 28 gulls can be seen in North America, with additional vagrant species showing up from time to time. Individual species look different depending on age and other factors. A gull goes through three feather molts in its first year.

Poisonous Seed Stash Discovered in the Netherlands – Black henbane contained in a hollow goat (or sheep) thigh bone sealed with a plug of black birch bark…from AD 70-200.

Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought - An analysis of six sea sponges—centuries-old creatures with an internal chemistry that holds secrets about climate history—points to global temperatures already having increased by 1.7 degrees Celsius due to human activity --- that’s more than scientists currently agree upon….so there is a flurry of activity to corroborate the finding.

What were the death tolls from pandemics in history? – The two most recent ones are COVID-19 and HIV/AIDS. Death from the 1918-1920 flu pandemic was larger than both together….and the population of the world was less then too.

Moments of hope and resilience from the climate frontlines – Drought then intense rains leading to rolling blackouts, damage to infrastructure, agriculture failures, mosquito spread diseases. Heat stress leading to deaths of people and wildlife, wildfires. Protecting and rehabilitating damaged habitats. A new normal….not anyone ready. Heat officers to help residents cope. Coastal erosion (caused by coastal development, rising sea levels and storm surges). Taking two years rather than one to dry firewood in Lapland. Solar panels positive impact on health care in India (and anywhere where electric power is unreliable). Crop irrigation required where it previously was not. Learning from our past, simpler lifestyles.

European Imports of Russian Pipeline Gas Dropped by Half Last Year - Europe has implemented measures to conserve energy and has ramped up wind and solar power. Last year, Germany, the largest economy in Europe, drew more than half of its power from renewables for the first time.

Could Climate Change Cause More Lakes to Turn Bright Pink? – Single-celled, salt-loving halobacteria. There is a new pink pond at the Kealia Pond National Wildlife Refuge in Hawaii…but it has been happening in the Great Salt Lake’s North Arm for several decades.  The number of pink ponds could increase with warmer temperatures increasing evaporation (and increasing the salinity of waters).

Next Solar Eclipse, In April, Expected to Attract Upwards Of 4 Million Tourists - Great American Eclipse has developed a geographic model to estimate how many people will travel to see the April eclipse. This model predicts that between 1 and 4 million people will travel to the path of totality. Texas is expected to receive the majority of visitors, followed by Indiana, Ohio, New York, Arkansas, Illinois, Pennsylvania, Vermont, Oklahoma, Maine, and New Hampshire.

Abandoned Lands: A Hidden Resource for Restoring Biodiversity – Nature colonizing abandoned land…maybe we need to learn to help it along. The amount of land under agriculture globally has been in decline since 2001. Sometimes the abandonment is not driven by economic, demographic, or social factors, but by pollution or industrial disasters. Hundreds of square miles of radioactive former farmland around the stricken nuclear reactors at Chernobyl in Ukraine and Fukushima in Japan are now within exclusion zones and could be without human occupation for centuries to come.

How to build for aging in place - Aging-ready homes address two core needs—single-floor living and bathroom accessibility—by providing a zero-step entry, a first-floor bedroom, and a full first-floor bathroom with at least one accessibility feature. Today only 10% of American homes are ‘age ready.’ When my husband and I bought our current home, we were conscious of buying something that would help us age-in-place. Everything is on one floor except for the laundry room….so we might have to eventually add an elevator to the house.

The Mississippi is Mighty Parched – The river south of Memphis has narrowed considerably in the past 2 years. Barge companies reduced the weight carried in many shipments in September because the river was not deep enough to accommodate their normal weight. Much of U.S. grain exports are transported down the Mississippi; the cost of these shipments from St. Louis southward has risen 77% above the three-year average. The lack of freshwater flowing into the Gulf of Mexico has also allowed saltwater to make its way up the river and into some water treatment plants in southern Louisiana.

Electric Cars Are Transforming America’s Truck Stops – I’ve been noticing the changes described in this article as I travel. More of truck stops have banks of chargers…and the Pilot just north of Denison has better food and a larger shopping/eating area… Adding charging equipment for electric cars is a major transformation for truck stops and travel centers but represents a new business opportunity.

The seed guardians in the Andes trying to save the potato – Climate change/disease are risks that all species are facing. There are 1,300 varieties of potato growing in the Andes. Potato Park, located near the Peruvian town of Pisac, was founded by six indigenous communities in 2002 to preserve the genetic diversity of potatoes grown in the region, as well as the cultural heritage of the people that grow them.

Chemical Analysis of Viking Combs Hints at Long-Distance Trade – 85-90% of the combs found in a Viking settlement in Germany, came from northern Scandinavia – made of the antlers of reindeer. So large scale trading between the two sites was happening as early as AD 800.

America’s largest transit bus charging station & microgrid open in Maryland – The headline caught my eye because I lived in Maryland for over 20 years – 8 of those in the county where this is happening! I hope other states have the same sorts of projects in the works.

NASA Finds More Than 50 Super-Emitters of Methane – Finding them is only the first step….how many of them will be situations we can reduce or stop the emission?

Iron induces chronic heart failure in half of heart attack survivors – This study prompted testing of iron chelation therapy to remedy or mitigate the effects associated with iron in hemorrhagic myocardial infarction patients.

Unique Bronze Age belt discovered near Opava – Half my ancestors came from the area that is now the Czech Republic…I am drawn to articles about the history of the region.  The belt is quite beautiful…but was it a practical item of apparel?  

What happens if our circadian rhythms are out of whack? – WHO has proclaimed that disrupted circadian rhythms are a probable carcinogen. The study discussed in this post was about the mechanism that circadian rhythm disruption triggers lung tumors.

View 16 Breathtaking Images from the Nature Conservancy’s Annual Photo Contest – Take a little break….look at awesome images of our world.

Mississippi River Basin adapts as climate change brings extreme rain and flooding – This year the stories about extreme weather seem to be more frequent – and wide ranging in terms of water. The Mississippi was low enough for barge traffic to be impacted because of drought…yet there were floods along part of the river just last summer.

Eye-opening discovery about adult brain's ability to recover vision – An unexpected success…opening new ways to treat a vision impairment (LCA) and maybe prompt a re-look about how the adult brain can re-wire itself relative to vision.

The World’s Whitest Paint May Soon Help Cool Airplanes and Spacecraft – A way of making paint that was previously too thick/heavy for things that move. The thicker version works for homes and buildings. We’ll need this technology to reflect heat without expending energy!

Greater cloud cover may be narrowing the gap between daily high and low temperatures – Simulating clouds explicitly. Trying to understand why nights are heating up faster than days across the globe.

How an asteroid impact would transform the food we eat – Thought provoking…and scary. Right now, I am beginning to wonder how the level of drought in the US is going to change the food we eat…or will we eat the same way but pay much higher prices.

A Field Guide to Unexpected, Out-of-Place Wildlife – Why wildlife shows up in the ‘wrong’ place… I had read about the shifting range of armadillos last spring (was reminded of it by the reference to the Virginia opossum in this post).

State Of the Birds Report: More Than Half of U.S. Bird Species Are Declining – Sad….another indicator that the Earth is changing.

Economic losses from hurricanes become too big to be offset by the US if warming continues – I’ve been wondering about this since Hurricane Harvey and finally there is some analysis of the data…but, so far, it does not seem to be changing the way we deal with the aftermath of these catastrophic storms. The dominate idea still seems to be ‘rebuild.’

Life expectancy improves in some countries after big drops in 2020 – but US and others see further falls  - The life expectancy at birth in the US was 79.8 in 2019 and was down to 77.4 in 2021. It might take a few years until the impact of COVID-19 on life expectancy is fully understood. It seems to me that there are other cultural changes that happened concurrent with the COVID-19 pandemic that could impact life expectancy in the US into the future: reduced vaccination rates, reduced trust in medical professionals, increased belief in whatever is said on social media and conspiracy theories, increased stress/mental health challenges, etc.

The Clean Water Act at 50: Big Successes, More to Be Done – The Act was passed the year I graduated from high school. I had done a project about algae as pollution indicator in the streams around Dallas, Texas in the fall before so I was aware of water pollution issues of the time. It is frustrating that there is still so much to be done….

New model of Alzheimer’s as an autoimmune disease – A new perspective….maybe leading to new therapies in the future.

Ancient Maya Cities Were Polluted with High Levels of Mercury – The Maya coated surfaces (walls and floors and bodies) with cinnabar…and the mercury from that leached into the water supply and soils. Chronic mercury poisoning causes tremors, weakened vision and hearing, and paralysis! The contamination at some sites is high enough that archaeologists need to use mitigation techniques and protective gear.

Young kids avoid one learning trap that often snares adults – Young kids are not as good at focused attention as adults which means they notice new things happening away from a ‘focus area’ more quickly…..but focused attention can also mean learned inattention in adults which might not be the best strategy in all situations.

After Three Summers, Man Finally Gets Photos of Hummingbird with Rainbow Wings – Beautiful pictures. They prompted me to look up why hummingbird feathers can show the colors of the rainbow. I found a Science Daily post from back in 2020 that offers an explanation.

US National Integrated Drought Information System – 68.4% of the US is abnormally dry…46% is in moderate drought…27% in severe drought. Use the location tab of this page to select state or county level maps color coded for their drought status. Where I live, we are in moderate drought.

Autumn in the Adirondacks – Leaf color has not been impacted by the drought in the Adirondacks. The pictures are from the Landsat 9 satellite. I’m enjoying the color from the ground – even with the drought here in Missouri making it not as colorful as it probably was in prior years.

Why cork is making a comeback – The main product mentioned in the article was cork stoppers….but I thought of the calm I felt when I walked into the University of Michigan’s Law Library with a tour group and realized how much the cork floor muffled our footsteps. It was the highpoint of the trip with my daughter when she was considering the school for her undergraduate studies.

Blue fibers found in dental calculus of Maya sacrifice victims – Analysis of more than 100 sacrifice victims found blue fibers in the mouths of 2 of them. Are the fibers from blue gags left in the mouths of victims over and extended time? Similar pigment called Maya blue has been found in other sites where it may have been used to paint the bodies of sacrificial victims. Another archeological mystery…

See the buzzworthy winners of the Wildlife Photographer of the Year competition – Eye candy for the week.

Millions of Americans are losing access to maternal care. Here’s what can be done – 36% of the counties nationwide – largely in the Midwest and South – constitute “maternity care deserts,” meaning they have no obstetric hospitals or birth centers and no obstetric providers. That does not bode well for the health of mothers and the next generation.

These stunning satellite images look like abstract art – and they reveal much about our planet – 8 images selected from US Geological Survey satellite images of the Earth’s surface.

Engineers weave advanced fabric that can cool a wearer down and warm them up – Maybe the ‘cool down’ of this technology (if it can be developed) will help us deal with climate change more effectively. There are already beginning to be more heat related deaths and there will be some occupations that will become impossible without technology to cool the body in outdoor environments.

Rainfall is becoming more intense in most of the US – East of the Rockies…there is increasing precipitation intensity. Water resource management is more challenging. Flooding risk is going up too.

USGS Public Lecture Series – A wide range of topics including volcanoes in Alaska, earthquake early warning for all, migratory big game, droughts and groundwater quality, modernizing the national water information system….and many more. I am beginning to work my way down this YouTube playlist.

Archaeologists Uncover Hundreds of Colorful Sarcophagi at Saqqara—and They’re Not Done Yet – The seeming endless interest in Egypt…sustained by continuing new finds.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

Major infrared breakthrough could lead to solar power at night – A very small amount of energy was produced in the test…more research required for practical application.

Restoration Reveals Engravings in Egypt’s Temple of Esna – Follow the link at the top of the post to see a few more pictures of the restored engravings.

What we are still learning about how trees grow – A new study finds that tree growth is limited by cell growth rather than photosynthesis which has been assumed to be the limiting factor previously. The models that predict how much carbon forests can absorb need to be updated.

Spring Flowers are Blooming Earlier in Greater Yellowstone – The recovery of detailed records made in the 1970s by Frank Craighead of when flowers bloomed is helping document changes…help restoration planners determine the best seed mixes for native plants…try to mitigate the impact of climate change.

Cutting air pollution emissions would save 50,000 US lives, $600 billion each year – Yet another reason to take actions to dramatically reduce air pollution.

Traces of an ancient watery world in Capital Reef – Satellite views of Capitol Reef National Park…and the story in the rocks.

Prehistoric feces reveal parasites from feasting at Stonehenge – A piece of trivia: beef and pork were spit-roasted or boiled in clay pots but the evidence of particular parasites in coprolites reveals that liver and lungs from an infected animal were consumed raw or undercooked.

Vangelis, famed film composer and synth pioneer, dead at 79 – I remember going to see Chariots of Fire when it first came out in the early ‘80s….and the unforgettable music. This obituary post includes a link to a YouTube video with the music.

How cranberries could improve memory and ward off dementia – I like cranberries…but eating a cup (equivalent) per day is a lot. In the study they used cranberry powder.

More heat, more drought: New analyses offer grim outlook for the US west – The latest seasonal outlook projects the drought to continue across virtually the entire American west through the summer. New research suggests that Colorado, Utah, and Wyoming will increasingly look like the Southwest as temperatures continue to rise.

Winners of Wildlife Photography Competition Show the Power of Water – Starting out the gleanings list with some eye candy this week.

Personality traits are associated with well-being and satisfaction in life after work – My husband and I have transitioned to ‘life after work’ and seem to have easily established ‘new fulfilling life patterns.’ In an odd way, the COVID-19 pandemic has helped us focus on the most important aspects of those patterns.

A New Study of the Permian Basin – a US oil-drippling hotspot is kicking out far more methane that we thought – I keep thinking that the technology to reduce emissions in the fossil fuel extraction process has improved from the early days. Maybe it has…maybe the hasn’t. The industry may not be motivates. Is it all about maximizing profits for them and their stockholders…everyone else doesn’t matter?

Toad Wisdom – A story of webs of life from the Prairie Ecologist.

European earthworms reduce insect populations in North American forest – Even small invasive species can have a significant impact.

Mapping Inequality – Redlining in New Deal America – An introduction….then downloads and data for maps for urban areas across the US from the 1930s.

Top 25 birds of the week: birds on flowers – Enjoy some photographs of birds…flowers…springtime!

Scents help researchers identify contents of Egyptian vessels – The smells of ancient Egypt!

Norway at new record high 92% plugin EV share in March – Hopefully the EV share in the US will start climbing more rapidly.

“Flash droughts” coming on faster, global study shows – Extreme weather….not all on the wet side.

Can cloud seeding help quench thirst of the US West? – New research on an old idea…many states increase their use of the technology.

Fresh water from thin air – Another technology that might help dry regions….using hydrogels (like the ones currently used in diapers!).

What’s The Construction Industry Blueprint to Cut Carbon? – I wanted more specific examples…was a little disappointed that this article did not provide them, but maybe that would have made it a long article! I hope to see more on this topic.

Higher education must reinvent itself to meet the needs of the world today. Enter the distributed university – The pandemic has highlighted the challenges the current higher education model is facing. The ideas in this post are a start but don’t seem to be fully developed to push into full implementation. More work needs to be done to enable transition from the existing model to a new one that is more responsive to the needs not only of undergraduate students but for graduate students and continuing education. The sources of money in the current model don’t match up well. For example – in the US the sports programs (football) is a big money maker for many universities; how does that map into the new model (or do we want it to).

Upcycling plastic waste into more valuable materials could make recycling pay for itself – Hope this research can be transitioned into commercial use….we have to improve the recycling processes that are being used today. Too much is still ending up in landfills.

Fossil pollen reveals the African origins of Asia’s tropical forest – Research on Borneo’s Dipterocarps (very large trees with buttress roots, smooth/straight trunks, high crown) using fossil pollen reveals their origins in Africa…spread through India before it crashed into Asia…and then to Southeast Asia. The forests in India shrank as the climate became drier. These trees need a wet, seasonal climate to survive.

Mummification in Europe may be older than previously known – Analysis of bodies found in Mesolithic shell middens in Portugal reveal that they were probably mummified before being placed there 8,000 years ago. The description of the way the researchers came to that conclusion was interesting…a lot has been learned about forensics since the 1960s when the bodies were originally found. The oldest intentional mummification known before this finding was from the Chinchorro hunter-gatherers living in the coastal region of the Atacama Desert in shell middens (around 7,000 years old).

Lake Powell Reaches Lowest Level Since 1980s – The drought continuing in the west….

The myths and realities of modern friendship – Thought provoking. The ways we communicate with each have changed a lot over my lifetime!

The climate math of home heating electrification – The rationale for moving to heat pump heating/cooling as quickly as possible.

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

The subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.
