Phys.org / RNA droplets may have helped start life on Earth
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Medical Xpress / Youth type 2 diabetes cases in Colorado have risen nearly 10-fold since 2002
Type 2 diabetes has traditionally been a disease that has affected mostly middle-aged and older adults. But new research from the U.S. to be presented at the Annual Meeting of the European Association for the Study of Diabetes ...
Phys.org / Layered rock in India shows potential signs of microbial life dating to 3.5 billion years ago
A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth. Their study, published in the Proceedings of the National Academy of Sciences, describes the biosignatures ...
Phys.org / Laser-cut aluminum foil could replace costly terahertz polarizers
When physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) needed a key component for their terahertz experiments, they ran into a frustrating problem—they needed tiny optical devices, known as wire-grid ...
Medical Xpress / New brain cell formation stalls in adults with depression, study shows
Findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons suggest that the trickle of neurons created in the adult hippocampus could be instrumental in preventing depression. ...
Phys.org / Mars Curiosity rover discovers massive field of polygons
The surface of Mars is home to some of the most breathtaking and awe-inspiring landscapes in the solar system. This is primarily because the Red Planet lacks several resurfacing processes that Earth possesses, including plate ...
Tech Xplore / AI agents can build consensus on a scale humans can't
Everyone is familiar with the situation: A larger group of people plans to visit a restaurant together, but it can take time and sometimes a great deal of patience to agree on a time and place to meet. The better the participants ...

China said on Sunday it was postponing its planned ambitious Chang'e-7 lunar mission, which was set to carry out explorations including searching for water ice on the moon.
Phys.org / Thawing Arctic riverbeds may erode up to 10 times faster than unfrozen ground
Sometimes science throws up the unexpected. When a team of researchers set out to model river erosion in Canada's High Arctic, they did not expect the findings to defy common sense.
Phys.org / An echo of Einstein: An unexpected link between whale calls and special relativity
Standing on the sandy, windswept shores of Provincetown, Massachusetts, people may find themselves squinting at the horizon, waiting for a whale to make its grand entrance with a spectacular breach.
Phys.org / Thunderquakes enable seismic imaging of Earth's shallow subsurface
Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State.
Medical Xpress / How the brain distinguishes the consequences of our own choices from events beyond our control
A study led by the University of Oxford has identified the brain mechanisms that help us work out whether the consequences we experience are caused by our own actions or by circumstances beyond our control.
