Phys.org / Fuego volcano activity that triggered evacuations in Guatemala is decreasing, but risks remain
Activity at Guatemala's Fuego volcano that began Monday morning and caused widespread evacuations is gradually decreasing, authorities said Wednesday.
Medical Xpress / Why do people's pupils dilate when they're surprised? Researchers explain
When people encounter new information that challenges their expectations, their pupils are likely to dilate. This physiological response is a sign that something is happening in the brain to help the person adapt to the new ...
Phys.org / Using the Earth's magnetic field to hunt for axions and dark photons
Dark matter's existence is all but certain—astronomers believe it makes up about a quarter of the universe's total energy content—yet its true identity has eluded us for decades. Two of the leading candidates for dark matter ...
Phys.org / Experimental drug turns cancer's favorite fuel against it
Cancer cells have a voracious appetite for sugar—using it to fuel their rapid growth. This is why many scientists have tried to develop drugs that block cancer cells' metabolism by cutting off their sugar supply.
Medical Xpress / A 'molecular switch' that heals the gut—and that colorectal cancer hijacks to spread
Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of ...
Phys.org / Damaging coastal storm conditions have become twice as frequent at a New Jersey Beach since 1979
Storm conditions capable of causing major coastal erosion at New Jersey's North Beach on Sandy Hook are occurring about twice as often as they did in 1979, according to Rutgers researchers. The finding offers new evidence ...
Phys.org / New semiconductor maser operates continuously above room temperature
Lasers have become indispensable in everyday life and research, with applications ranging from data transmission and metrology to manufacturing. Masers, by contrast, have so far found hardly any practical applications.
Tech Xplore / Human-aware robots adapt to partners, reducing back strain during team lifting
When people work in pairs or teams, they can often solve a wider range of problems, completing some tasks faster and more efficiently than they would alone. To assist users similarly to how other humans would, robots should ...
Phys.org / Attosecond X-ray method maps early electron motions that trigger chemical reactions
All chemistry starts with a push from electrons. In the early moments of a chemical reaction, it's the movement of electrons that initiates the breaking of old chemical bonds and forging of new ones, transforming one molecule ...
Phys.org / Nanowires restore key functions in aging T cells
For decades, scientists have accepted that the immune system naturally weakens with age. Georgia Tech biomedical engineer and Carl Ring Family Professor Ankur Singh wasn't convinced. Then the COVID-19 pandemic made the stakes ...
Science X / HIV's hidden history: New study reveals much deeper roots stretching back millions of years
Researchers used to think that HIV and its relatives were pretty recent things, maybe only a few hundred years old. But a growing body of evidence now suggests their history is far more ancient, with viruses closely related ...
Phys.org / 'Spooky' particles transit DC suburbs, a step toward a quantum network
In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs. The arrival of those signals at their destination marks a significant step toward ...
