Succulent plants protect themselves through a variety of adaptation strategies
How do plants adapt to drought and heat? New studies on plants of the Canary Islands show that adaptation is not determined by a single character but by the interaction of entire sets of characters. Even closely related plants can follow very different paths.
Local political crises are breaking the global unity of youth activism, study finds
A new study reveals that the image of a seamless global youth climate movement is fracturing as activists in the "periphery" feel increasingly sidelined by Western-centric leadership. By investigating why these local chapters face a "crisis of connection," the research exposes

Kelp: The planet's other forest crisis
The decline of California's kelp forests since the marine heat wave of 2013–17 has seen only minor recovery despite heroic efforts at restoration carried out by scientists, fishermen, coastal tribes, volunteer divers and conservationists. Nor is the threat to kelp localized.
Southern California air board rejected pollution rules after AI-generated flood of comments
The opposition appeared overwhelming: Tens of thousands of emails poured into Southern California's top air pollution authority as its board weighed a June proposal to phase out gas-powered appliances. But in reality, many of the messages that may have swayed the powerful
Fast-paced lives demand faster vision: Ecology shapes how 'quickly' animals see time
Animals don't just see the world differently from one another, they experience time itself at dramatically different speeds. That is according to a new study that considered 237 species across the animal kingdom, and which revealed that how fast an animal lives and moves
Global warming and heat stress risk close in on the Tour de France
The progressive rise in temperatures poses a growing threat to the staging of summer sporting events in Europe and, more specifically, to the Tour de France, due to the increasing risk of heat stress for athletes. This is one of the conclusions of a study published in

New technology reveals hidden DNA scaffolding built before life 'switches on'
For decades, scientists viewed the genome of a newly fertilized egg as a structural "blank slate"—a disordered tangle of DNA waiting for the embryo to wake up and start reading its own genetic instructions. In research published in Nature Genetics, Professor Juanma Vaquerizas
The surprising vaccine side effects that can improve long-term health
People often focus on the bad side effects of vaccines, but they can have some great side effects too, says columnist Michael Le Page. They don’t just protect us from contagious diseases but can also lower the risk of dementia and heart attacks
Scientists engineer bacteria to eat cancer tumors from the inside out
Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-exposed edges — but

Massive US study finds higher cancer death rates near nuclear power plants
A sweeping nationwide study has found that U.S. counties located closer to operating nuclear power plants have higher cancer death rates than those farther away. Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 and 2018, adjusting for
For Northeast blizzard, everything was just right to roll up a monster snowfall
The nor'easter smacking much of the Northeast with nearly 3 feet of snow in places is as classic and powerful a blizzard as you can get, the strongest in a decade and up there with the most intense in history, meteorologists said.
Space lasers reveal oceans rising faster than ever
A new 30-year analysis reveals that melting land ice is now the main force behind rising global sea levels. Researchers discovered that oceans rose about 90 millimeters since 1993, with most of the increase coming from added water mass rather than just warming expansion. Ice
Training harder could be rewiring your gut bacteria
Training harder may do more than build muscle—it could transform your gut. Researchers found that intense workouts change the balance of bacteria and important compounds in athletes’ digestive systems. When training loads dropped, diet quality slipped and digestion slowed,
Scientists reverse muscle aging in mice and discover a surprising catch
A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up
Image: Curiosity rover surveys boxwork region of Mars
NASA's Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork formations were created billions of years ago when

Probability underlies much of the modern world—an engineering professor explains how it actually works
Probability underpins AI, cryptography and statistics. However, as the philosopher Bertrand Russell said, "Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means."
Staple crops are a major contributor to global deforestation, says study
Rice, maize, and cassava crops cumulatively account for approximately 11% of total global deforestation—exceeding that of cocoa, coffee, and rubber—according to an analysis between 2001 and 2022, published in Nature Food. These staple crops should not be overlooked in global

EPA criminal sanctions align with a county's wealth, not pollution, study finds
When the federal government brings its toughest environmental enforcement actions against polluters, they tend to be in communities of greater wealth, not the most polluted places. That's the takeaway from a new paper co-authored by a Washington State University researcher that
Animal muscles inspire biomaterial design for agriculture, fabrics and medicine
Natural muscle fibers are made up of spring-like proteins that can contract and stretch without losing their original form, dissipate mechanical energy as heat and maintain incredible tensile strength for all sorts of physical functions. Engineers at Washington University in
Why the planet doesn't dry out all at once: Scientists solve a global climate puzzle
