2/16/2026 Journal of Advanced Research Association between exposure to microplastics and lipid disorders: A case-control study – Study with 239 patients aged ≥18 years who underwent fiberoptic bronchoscopy with bronchoalveolar lavage fluid (BALF) collected. Microplastics in BALF were identified and quantified using laser direct infrared spectroscopy. Fourteen main types of microplastics were detected in BALF with PE being dominant. Exposure to microplastics was associated with elevated levels of total cholesterol.

2/16/2026 National Parks Traveler A Day in the Park: Canyon de Chelly National Monument – This article reminded me of a visit to the park in 1983! We hiked the White House Trail, and I remember wading across a stream with the 4 of us holding hands just in case there was a pocket of quicksand. We managed to get through with neither of the two cameras getting dipped in the water.

2/13/2026 Science Daily Scientists make microplastics glow to see what they do inside your body - A new study proposes an innovative fluorescence-based strategy that could allow researchers to track microplastics in real time as they move, transform, and degrade inside biological systems.

2/15/2026 Our World in Data Four minutes of air conditioning - In at least 45 countries, the average residential electricity use per person for an entire day is less than the electricity that is required to power an air conditioner for one hour. In India, the daily electricity budget is sufficient for only 44 minutes of AC. In Nigeria, just 13 minutes; and in South Sudan, just 4. Most people in some of the world’s hottest countries do not use AC. The most recent data from the International Energy Agency suggests that just 5% of households in India, 6% in South Africa, and 16% in Brazil had air conditioning. In the very poorest countries, almost no one has it. In colder countries, we wouldn’t accept people freezing in their homes. The opposite is also true: we shouldn’t accept people working and living in oppressive heat without ways to cool themselves down.

2/15/2026 Planetization South Carolina Mapping Tool Tracks Marsh Migration From Sea Level Rise - A new mapping tool funded by the National Fish and Wildlife Foundation maps South Carolina’s shifting salt marshes, which are pushing inland as seawater levels rise. The mapping tool translates theoretical projections into actionable data. For a more detailed explanation and videos see the article on Governing.

1/23/2026 The Scientist Antibiotic Resistance Is Rising: 4 Trends Could Change That Course - Antibiotic resistance is sometimes framed as an inevitable catastrophe. But I believe the reality is more hopeful: Society is entering an era of smarter diagnostics, innovative therapies, ecosystem-level strategies and policy reforms aimed at rebuilding the antibiotic pipeline in addition to addressing stewardship. For the public, this means better tools and stronger systems of protection. For researchers and policymakers, it means collaborating in new ways. The question now isn’t whether there are solutions to antibiotic resistance – it’s whether society will act fast enough to use them.

2/11/2026 Smithsonian Magazine Ice Fishermen Catch Record-Breaking 244-Pound Atlantic Halibut After Hours-Long Struggle - The fish measured more than six and a half feet long and easily broke the previous record—194 pounds—for the largest halibut caught on the Saguenay, which had been set last winter. The record-breaking Saguenay fish was the 27th halibut hooked this winter as part of the research project. After organs are removed for study, the fishermen will get to keep and split roughly 170 pounds of meat.

2/16/2026 Science Daily Microplastics have reached Antarctica’s only native insect - Scientists have discovered that Belgica antarctica — a tiny, rice-sized midge and the southernmost insect on Earth — is already ingesting microplastics in the wild. While lab tests showed the hardy larvae can survive short-term exposure without obvious harm, those exposed to higher plastic levels had reduced fat reserves, hinting at hidden energy costs.

2/16/2023 Cool Green Science 8 of the World’s Little-Known Wildlife Migrations – Lots of different kinds of animals of this list!

2/16/2026 Yale Environment 360 Despite Rollbacks, U.S. Fossil Fuels Face Tough Road Ahead - The weakening of environmental regulations belies the downward trajectory for fossil fuels under President Trump. Today, the U.S. coal fleet is the smallest it has been in decades, having shrunk roughly in half since 2010. There are no new coal plants under construction. Oil is expected to stagnate as global production outpaces demand. Oil executives say the shale boom may be coming to an end. Natural gas remains a bright spot for U.S. fossil fuels as a recent boom in gas exports continues to drive demand for U.S. gas

How Has U.S. Energy Use Changed Since 1776? – Historical perspective. Coal, petroleum and natural gas did not surpass renewables (i.e. wood) until 1885!

Is this the end for Easter Island's moai statues? – The moai are made from tuff, a volcanic rock largely composed of compressed ash. This type of stone is porous and unusually soft. The wind and rain do not treat it kindly. Weathering of the moai appears to have increased sharply during recent decades; drier weather followed by very heavy rains, more wildfires, rising sea level  and increased wave event have all contributed.

20 Incredible Nominees for the BigPicture Natural World People’s Choice Award – Some great photography.

In Yellowstone, Even Animals Sometimes Make Mistakes – A bison stumbled into Grand Prismatic Spring…and there was no happy ending.

London Inches Closer to Running Transit System Entirely on Renewable Power - London will source enough solar power to run its light railway and tram networks entirely on renewable energy. The deal brings Transport for London closer to its goal of running its entire transit system, including its sprawling underground railway network, on renewable energy by the end of this decade.

Time For Canada to Dump the Big Three & Go Electric with China – Something valid for Canada to consider…certainly more forward looking than subsidizing old technologies.

The end of tuberculosis that wasn’t - In the late 1980s, many thought the fight against tuberculosis (TB) had been won. A disease that had plagued humans for at least 9000 years was on the path to being eliminated. Three factors raised concerns about the resurgence of tuberculosis in the United States and rich countries in Europe in from mid-1980s and 1990s: HIV/AIDS epidemic, the rise in drug-resistant tuberculosis, and higher rates of TB in foreign-born populations.

The US’s asbestos U-turn: why the Environmental Protection Agency is reconsidering its ban - Each year, around 40,000 deaths in the US and about 5,000 in the UK are attributed to asbestos exposure. If the US ban is lifted, it’s possible that the number in the US could increase over the coming decades while those in the UK will continue to fall. While global consensus moves toward stricter regulation, the US now finds itself at a crossroads, between scientific evidence and pressure from industry.

Inside Egypt’s Enigmatic $1 Billion Grand Museum - During a press conference on June 14, Egyptian Prime Minister Mostafa Madbouly said the official opening was postponed due to “current regional developments”—loosely referring to the then-escalating conflict between Israel and Iran.

These Colorful Satellite Views Reveal Our Forests in Unprecedented Detail and Showcase the Potential of the New Biomass Mission - The European Space Agency’s satellite will measure trunks, branches and stems in forests to shed light on how much carbon is stored in trees across various continents. The example image of the Beni River in Bolivia shows a lot of oxbow lakes!

From Dead Dirt to Healthy Soil in 7 Simple Steps – The articles from Leaf & Limb are always full of practical suggestions. I am doing all 7 of these steps in my yard!

A Large, Invasive Lizard Was Spotted in a California Park – An Argentine black and white tego. Another invasive...probably a pet that escaped or was released. Tegus have established populations in several parts of Florida, where they’ve been declared an invasive species. The lizards have also infiltrated southeast Georgia, and they have been spotted in Alabama, Texas, South Carolina and Louisiana.

Ultra-processed foods are everywhere — and they’re quietly raising health risks - The effects of UPFs can pile up over time, adding to the risk of heart attack, stroke and other serious health issues by raising blood pressure and blood sugar levels. While ultra-processed foods include obvious culprits like potato chips, candy and frozen pizza, there are also some that people may believe are good for them, such as packaged granola bars, sports drinks and fruit-filled yogurt.

The hunt for Marie Curie's radioactive fingerprints in Paris - Marie Curie worked with radioactive material with her bare hands. More than 100 years after her groundbreaking work, the lingering radioactive fingerprints she left behind are still measurable.

Is it better to neglect your garden? – Maybe…except for stepping in strategically to keep invasives from taking over. My yard is a work in progress but the goal it to make changes that mean it will require less and less intervention over time.

Sequoia And Kings Canyon National Parks' Giant Sequoia Trees - Giant sequoia trees can live to be more than 3,000 years old! Large giant sequoias often owe their size to rapid growth rather than age, so an old giant sequoia will not necessarily be the largest specimen. While these giant trees are more resistant to threats, they are not immune. Climate change influences the growth and survival of sequoias, particularly in the form of droughts with unusually high temperatures known as “hotter droughts.”

5,000-Year-Old Bread Buried in Bronze Age House - The flatbread, which measures, five inches wide and one inch thick, is among the earliest known baked items ever discovered. Analysis determined that it was made from a coarsely ground flour made of emmer, a type of ancient wheat, and lentils. A modern bakery has already begun to reproduce and sell breads based on the ancient recipe.

Versailles’s Hidden Scientific Legacy to Surface in a Major U.K. Exhibition - The five-mile-squared grounds were mapped out by geometricians and astronomers; keeping the 14,000 fountains bubbling further required developing an unprecedented hydraulic engineering system. AND… Giovanni Domenico Cassini, who headed the Paris Observatory, turned skyward, mapping the moon with a precision that wouldn’t be matched until the late 19th century. AND… Hundreds gathered in the courtyard of Versailles to watch the flight of a hot-air balloon, agronomists developed a hardier potato capable of feeding the masses, and an inoculation against smallpox was discovered.

Air conditioning causes around 3% of greenhouse gas emissions. How will this change in the future? – The article concludes: “Rather than lamenting air conditioning's impact on energy use, we need to accept that demand for cooling will increase, work on making it affordable for those who need it most, and build efficient solutions that ensure electricity grids worldwide can cope.”

Ancient Rome’s Appian Way Is Now a UNESCO World Heritage Site - Rome’s Appian Way, an ancient highway dating to the fourth century B.C.E., has been declared a UNESCO World Heritage site.

Could the shingles vaccine lower your risk of dementia? - The idea that vaccination against viral infection can lower the risk of dementia has been around for more than two decades. Associations have been observed between vaccines, such as those for diphtheria, tetanus, polio and influenza, and subsequent dementia risk. It may be the resulting lack of viral infection creating this effect. We need more research exploring in greater detail how infections are linked with dementia. This will help us understand the root causes of dementia and design potential therapies.

Chickasaw National Recreation Area's Monkey Tree Needs Some TLC - An Osage orange tree estimated to be about 130 years old with three thick spreading trunks that generations of children have played on.

Divers Discover Mesmerizing Roman Mosaic Beneath the Sea – Near Naples…a villa in a city known as the Las Vegas of the Roman Empire…now under water.

Healthy diet with less sugar is linked to younger biological age – The correlations between a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.

Agriculture: Less productive yet more stable pastures - Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.

Anne Boleyn’s Childhood Home Is Restored to Its Tudor Glory – The interiors of rooms restored to the style they had during Anne Boleyn’s time.

Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire – Forests in some parts of the world, like the American West, probably do not have the potential to help curb climate change.
