Scientists discover the nutrient that can supercharge cellular energy
Researchers discovered that leucine, a nutrient found in protein-rich foods, can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. The breakthrough uncovers a powerful new link between diet and cellular energy — with possible implications
MIT scientists discover amino acid that helps the gut heal itself
MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged
Who reports wildlife the most? 300,000 citizen science records uncover participation bias
In recent years, citizen science methodology has gained significant momentum and is becoming increasingly important in large-scale ecological and conservation research. By involving volunteers, it enables a level of spatial and temporal coverage that would often be unattainable
Capturing an elusive step in molecular sandwich making

UNESCO warns a tsunami in the Mediterranean is inevitable
The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again
New evapotranspiration method could recover up to 30% missing tower energy
Evapotranspiration is a critical link between water, energy, and carbon. Scientists need to understand it well to accurately predict weather, droughts, streamflows, and even carbon emissions.
Scientists solve 320-million-year mystery of reptile bone armor
Reptiles have been growing armor in their skin on and off for hundreds of millions of years, but scientists never fully understood how it evolved. A massive new evolutionary study shows these skin bones appeared independently in multiple lizard groups rather than coming from a
New quantum sensor could count individual photons and hunt dark matter
Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that react to even the slightest temperature change. This level of precision could
Study finds key traits of condom 'stealthers'
Men with a strong sense of entitlement are three times more likely to commit "stealthing" during sex, according to a new University of the Sunshine Coast study. Stealthing, which has been criminalized in most Australian states over the past five years, is a form of sexual
Quantum sensors use atoms, electrons and light as ultra‑steady rulers
Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small that ordinary background noise can drown them out. Some sensors are already in

Optoelectronic synapse shows exceptional photoresponse for neuromorphic vision
Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the brain working together to resolve images with less
How economic growth in low-income countries can also protect biodiversity
For decades, environmental debates have been framed around a stark trade-off: economic growth lifts people out of poverty but comes at the expense of forests, wildlife, and climate stability. More people and richer diets mean more farmland and less nature.
An Ebola outbreak is spreading fast. Should you be worried?
A deadly Ebola outbreak in parts of Africa is raising international alarm. Still, experts stress that the chance of a pandemic is low
Extreme weather events may leave rivers unable to rebound
Severe droughts, intense floods, and heat waves are pushing river ecosystems beyond their natural limits of resilience. A review of data on river systems across several continents published in the journal Nature Reviews Biodiversity shows that, in most cases, nature is unable

Scientists have uncovered new evidence that Earth's continents are continuously reworked deep beneath the surface, offering fresh insight into how continents have evolved over billions of years.
Cities change storms, but the impacts depend on the storm itself
Cities don't just change the landscape, they change the weather. According to a new study analyzing tens of thousands of rain events in Texas, whether urban areas make rain worse, lighter or simply different depends strongly on the type of storm.

Contemporary archaeologists dig into the present—bringing those so often forgotten into the light
The classic image of an archaeologist is of someone unearthing a potsherd in Pompeii or opening a Viking grave to better understand the distant past. Yet the same methods can also be applied to our own time—a field known as contemporary archaeology.
Urban aerosols grow faster in polluted air, sharpening climate model gaps
Aerosols and clouds play a key role in Earth's climate budget. However, the extent to which they reflect solar energy depends heavily on how much water the particles can absorb. This so-called hygroscopicity has so far been represented in a simplified manner in climate models.
15 Australian companies switched to a four‑day work week. It went surprisingly well
In a 1930 essay, British economist John Maynard Keynes predicted that in 100 years time, technological advances would have displaced so much human labor that people would be working 15-hour weeks—if they worked at all.

Educational analysis of students' performance uses dynamic approach to include life's variables
Academic success at university could depend on the changing interaction between students' habits over time rather than fixed traits such as intelligence or total study hours. This conclusion is discussed in the International Journal of Computational Systems Engineering in a
129,000 years of crocodiles: What we know about Australasia's ancient apex predators
The sight of a saltwater crocodile basking on a mudbank is one of the most iconic and intimidating images of northern Australia. Yet the crocodiles that inhabit the region today are just the survivors of a much richer and stranger lost world.
How you map numbers in your mind isn't universal, even among people who read in the same language
Imagine taking out a 12-inch ruler and finding that the number 12 is on the left side and the number 1 is on the right side. For most native English speakers, this would be disorienting. We are used to seeing the numbers move from smallest to largest, from left to right. When
