Phys.org / 'Bathtub ring' hints at ancient Martian ocean
Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet's surface. The research was conducted by former Caltech postdoctoral ...
Phys.org / A backyard bug repellent is derailing bumblebees' ability to navigate
In the summer, many people turn to mosquito repellents to reduce the insects' buzzing and bites. One solution that has become increasingly popular in recent years is the Thermacell device, which releases vaporized, pyrethroid-based ...
Phys.org / CRISPR variant selectively targets tumor DNA
Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of scientists from Wageningen University & Research and Van Andel Institute has identified a way to exploit ...
Phys.org / Dark matter could explain the earliest supermassive black holes
A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, ...
Phys.org / Alien life may hide in plain sight: Statistical patterns across exoplanets move beyond traditional biosignatures
A research team has developed a new approach to detecting life beyond Earth that does not rely on identifying specific biological markers. Instead, the study suggests that life may be detectable through patterns emerging ...
Phys.org / Ancient charcoal sheds new light on how early humans fueled their lives
Nearly 800,000 years ago, early humans gathered along the shores of a lush lake in what is now northern Israel. Here, they returned again and again, hunting large animals, cooking fish over controlled fires, and organizing ...
Phys.org / Dark volcanic ash has visibly reshaped Martian surface since 1976
Noticeable change on Mars often takes millions of years—but the European Space Agency's Mars Express has captured a blanket of dark ash creeping across the planet in just decades.
Phys.org / Subaru telescope captures comet 3I/ATLAS composition change
The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon ...
Phys.org / 'Safe' fertilizer linked to extreme water quality loss in Canadian Prairies
Research published in Nature Water found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Researchers at the University of Manitoba and the University ...
Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
Phys.org / Multitasking quantum sensors can measure several properties at once
A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study the inner workings of ...
Phys.org / Copper's 'gatekeeper' could unlock cleaner energy future
A common mineral hiding in plain sight could hold the key to making copper production cleaner, faster and more efficient, just as global demand for the metal surges to power the energy transition. In an article published ...
