Fossilized bones are revealing secrets from a lost world

Tiny chemical clues trapped inside ancient bones are revealing what animals ate, the diseases they carried, and the environments they lived in.

Researchers have uncovered thousands of preserved metabolic molecules inside fossilized bones millions of years old, offering a surprising new window into prehistoric life. The findings reveal animals’ diets, diseases, and even their surrounding climate, including evidence of warmer, wetter environments. One fossil even showed signs of a parasite still known today. This approach could transform how scientists reconstruct ancient ecosystems

That which is small can still hold volumes.  :D

Missing for 200 Years, the Galapagos Rail Reappears Following Floreana Island Restoration

Centuries after they were made famous by Charles Darwin, and a century after they had become plagued by invasive rats and cats, the Galapagos Islands are well on their way to recovery.

Few events could better capture that recovery than the recent reappearance of the beautiful blue Galapagos rail, a bird which hadn’t been seen on Floreana island for 200 years.

After almost a decade of preparatory work, invasive rats, avian vampire flies, and domesticated cats were eradicated from the island thanks to the close coordination of several conservation groups from around the world working alongside the Galapagos National Park Directorate.



Restoration projects often foster the revival of rare species, or those believed to be extirpated or extinct. It's not often this dramatic, so this is exciting news.

Global warming could trigger the next ice age

Earth’s climate control system may cool so hard after warming that it freezes the planet over.

Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that bury huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this won’t save us from modern climate change, it may explain Earth’s most extreme ancient ice ages
.


It's not missing and it's not new.  This aspect of prehistoric climate change has been discussed for decades.  Also several decades ago, as climate change began to attract more attention, there were debates over whether the bounce effect would cause global cooling instead of global warming.  For a while there were disaster novels with an ice theme instead of a fire theme, before the current warming trend became more obvious.

However!  Even global warming will making some areas drastically colder.  Once the oceanic conveyor belt breaks -- which is already wobbling -- places like Britain will lose their warm currents and thus chill.

The western U.S. Tried to stop wildfires and it backfired

After a century of stopping fires, much of the West is now dangerously overdue for them.

Much of the western U.S. is overdue for wildfire, with decades of suppression allowing fuel to build up across millions of hectares. Researchers estimate that 74% of the region is in a fire deficit, meaning far more land needs to burn to restore healthy forest conditions. Catching up would require an unprecedented amount of controlled and managed fire.



I told you so.

Coffee-driven deforestation is making it harder to grow coffee, watchdog group says

Scientists have shown how deforestation leads to less rainfall in tropical rainforests. That's because the trees there soak up and release moisture, which rises to create clouds and more rain. Cutting down trees disrupts the cycle, reducing rainfall and leading to drought.

Drought, of course, makes it harder to grow coffee.

"When you kill the forest, you're actually also killing the rains, which is exactly what your crop needs to thrive in the long run," Higonnet says. "Even for people who don't much care about climate change and mass extinction, if they drink coffee and care about having coffee in the long run, this should be very scary for them."

Scientists Thought Parkinson’s Was in Our Genes. It Might Be in the Water

New ideas about chronic illness could revolutionize treatment, if we take the research seriously.

All told, more than half of Parkinson’s research dollars in the past two decades have flowed toward genetics.
But Parkinson’s rates in the US have doubled in the past 30 years. And studies suggest they will climb another 15 to 35 percent in each coming decade. This is not how an inherited genetic disease is supposed to behave.
Despite the avalanche of funding, the latest research suggests that only 10 to 15 percent of Parkinson’s cases can be fully explained by genetics. The other three-quarters are, functionally, a mystery.

Parkinson’s, it appeared, could be caused by a chemical.

Scientists find hidden rainfall pattern that could reshape farming

Where rain comes from may decide the future stability of global food production.

New research shows that crops are far more vulnerable when too much rainfall originates from land rather than the ocean. Land-sourced moisture leads to weaker, less reliable rainfall, heightening drought risk. The U.S. Midwest and East Africa are particularly exposed due to soil drying and deforestation. Protecting forests and improving land management could help stabilize rainfall and crop yields.



Allow me to point out that the Midwest used to have copious fencerows of trees and bushes, more pocket forests, and more farmhouse yards. People cut down most of those to clear a few more acres of farmland. The results have been poor across multiple areas including wildlife losses, soil erosion, worsening winds with less interruption, and of course the aforementioned droughts.

A hidden Antarctic shift unleashed the carbon that warmed the world

Ancient Antarctic water-mass upheavals unleashed stored carbon—and may hint at our climate future.

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea sediments show that ancient Antarctic waters once trapped vast amounts of carbon, only to release it during two major warming pulses at the end of the Ice Age. Understanding these shifts helps scientists predict how modern Antarctic melt may accelerate future climate change.

Scientists warn half the world’s beaches could disappear

Rising seas and human pressures are rapidly shrinking the world’s beaches and destabilizing the ecosystems that depend on them.

Human development and climate-driven sea level rise are accelerating global beach erosion and undermining the natural processes that sustain coastal ecosystems. Studies reveal that urban activity on the sand harms biodiversity in every connected zone, magnifying worldwide erosion risks
.


This sounds overly optimistic.  Beaches -- in the sense of pleasant sandy stretches -- are by definition shallow shorelines.  Little if any of that will be left given the rapid rise of sea level.  That's before factoring in other hazards such as sand theft, erosion, etc.  Of course, there will always be places where land and water meet, but those won't be in the same places in the future, wherever there is a shallow slope of land facing a large body of water.  Ironbound coasts, which have a high rocky cliff, are much less subject to inundation.

The five great forests that keep North America’s birds alive

Migratory birds that fill North American forests with spring songs depend on Central America’s Five Great Forests far more than most people realize. New research shows these tropical strongholds shelter enormous shares of species like Wood Thrushes, Cerulean Warblers, and Golden-winged Warblers—many of which are rapidly declining. Yet these forests are disappearing at an alarming pace due to illegal cattle ranching, placing both birds and local communities at risk.

Satellite images reveal the fastest Antarctic glacier retreat ever

Hektoria Glacier’s sudden eight-kilometer collapse stunned scientists, marking the fastest modern ice retreat ever recorded in Antarctica. Its flat, below-sea-level ice plain allowed huge slabs of ice to detach rapidly once retreat began. Seismic activity confirmed this wasn’t just floating ice but grounded mass contributing to sea level rise. The event raises alarms that other fragile glaciers may be poised for similar, faster-than-expected collapses.


Just because something is big, doesn't necessarily mean it's always slow. Climate change can move blindingly fast.

If I were there, I'd be crawling over that exposed plain searching for signs of life.  Antarctica is waking up.

Massachusetts is turning retired cranberry bogs into natural wetlands. They’re on track to rewild 1,000 acres

In November 2024, the DER funneled $6 million in grants to the restoration plan. According to the U.S. Fish & Wildlife Service, more than 500 acres of retired cranberry bogs have already been converted into wetlands — with hopes of restoring 1,000 acres in the next decade.

“These projects will transform degraded former cranberry bogs into thriving wetlands that will provide habitat to important species, flood control in time of storms, and access for all to beautiful natural areas,” Governor Maura Healey said in a statement.



This is a brilliant plan that will provide tremendous benefits for wildlife, as wetlands are among the most biodiverse communities. It will be especially helpful to migrating waterfowl of the Atlantic Flyway.

Life found in a place scientists thought impossible

Life defies limits in the deep sea—microbes flourish where Earth’s chemistry seems too extreme for survival.

Deep beneath the ocean, scientists uncovered thriving microbial life in one of Earth’s harshest environments—an area with a pH of 12, where survival seems nearly impossible. Using lipid biomarkers instead of DNA, researchers revealed how these microbes persist by metabolizing methane and sulfate. The discovery not only sheds light on deep-sea carbon cycling but also suggests that life may have originated in similar extreme conditions, offering a glimpse into both Earth’s past and the limits of life itself.



Extremophiles are fascinating.

Also, I really want to play with that blue serpentine mud to see if it would stand up to pinching, coiling, slabbing, or throwing and what would happen to it in a kiln.  It looks  like clay.  I am betting it would fire either to a soft blue-gray (nice) or a sky blue (so much wow).

Grand Prairie Friends Acquires New Property- Warbler Bend

Grand Prairie Friends (GPF) is thrilled to announce the purchase of Warbler Bend, a meandering 110 acres along the Embarras River in Coles County (IL). This purchase expands the Conservation Land Trust’s existing Warbler Ridge Conservation Area, now totaling almost 1,400 acres. Warbler Bend is GPF’s second property north of Highway 130, joining Warbler Bluff, located on Harrison St. Rd (Charleston).

Over the last decade, GPF has restored more than 1,200 acres at their Warbler Ridge Conservation Area including the addition of 90,000 trees, nine acres of wetlands and hundreds of acres of pollinator fields.

Connected to Lake Charleston to the north, and Fox Ridge State Park to the south, Warbler Ridge Conservation Area began in 2015, to connect these three landscapes to create an over 4,000 acre contiguous corridor for wildlife, natural habitats and public natural space for the community.



I am so excited! More riverfront!

Common pesticides may cause testicular damage and lower sperm counts

Widespread farm pesticides may be quietly undermining male reproductive health.

A decade-long review by George Mason University researchers reveals growing evidence that neonicotinoid insecticides—the world’s most widely used class of pesticides—may harm male reproductive health. The findings, based on 21 animal studies, show consistent links between exposure and reduced sperm quality, hormonal disruption, and testicular damage.



This will be useful to people seeking to ban or limit harmful pesticides. Perpetrators may not care about the environment or other humans, but they almost certainly care about their own virility.  Similarly victims who are lethargic about other health threats may rally over this one.
