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.

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.

5 simple (and cheap) things to make your house use less energy - Climate solutions for reducing home energy use can be extremely simple — and sometimes even free.

When Rivers Take a Weird Turn – Two examples where water (river) flows in unexpected ways…with satellite images from Landsat 9 of the two areas.

6 feel-good exercises to alleviate sore, achy feet – Some of these were new-to-me. I’m trying them all!

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.
