Phys.org / Unraveling the physics behind Kamchatka's 73-year earthquake cycle
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture ...
Medical Xpress / Grief best managed through talk therapy, evidence shows
Talk therapy is the best way to ease grief and depression following the death of a loved one, a new evidence review has concluded.
Phys.org / Real-time view inside microreactor reveals 2D semiconductor growth secrets
As the miniaturization of silicon-based semiconductor devices approaches fundamental physical limits, the electronics industry faces an urgent need for alternative materials that can deliver higher integration and lower power ...
Phys.org / Complex tongue bones, fleshy teeth on the roof of earliest known bird's mouth might have helped it snag food
Flying is really hard work. Compared to walking, swimming, or running, flying is the form of movement that takes the most energy and requires the most calories. That means that birds have had to evolve specialized ways to ...
Phys.org / The rise and fall (and rise again) of gold prices: What's going on?
In late January, the gold price reached an all-time peak of around US $5,500 (£4,025). January 30 saw one of the largest one-day falls in prices, which sank by nearly 10% after hitting a record high only the day before.
Phys.org / Cape Town project tests what hydroponic farming can do in urban spaces
Imagine a world where fresh vegetables and herbs sprout in the heart of our cities without the need for sprawling farms. Hydroponics—a method of growing plants without soil—uses a nutrient-rich water solution instead ...
Phys.org / Reshaping gold leads to new electronic and optical properties
By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light—and, as a result, its electronic and optical properties. This is shown by a study from ...
Phys.org / AI enables a who's who of brown bears in Alaska
A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season. ...
Phys.org / Banning lead in gas worked: The proof is in our hair
Prior to the establishment of the Environmental Protection Agency in 1970, Americans lived in communities awash with lead from industrial sources, paint, water supply pipes and, most significantly, tailpipe emissions. A dangerous ...
Phys.org / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Phys.org / Global plastics treaty negotiations: Success is still possible, researchers argue
Plastic pollution is causing severe problems worldwide. However, negotiations at the United Nations in Geneva last August did not result in the expected global plastics treaty. On 7 February 2026, the Intergovernmental Negotiating ...
Medical Xpress / Sleep medication linked to safer outcomes than antipsychotics for older adults with delirium
A large U.S. study suggests that older adults hospitalized with delirium may experience better outcomes when treated with trazodone, commonly used to treat depression and sleep problems, rather than commonly used antipsychotic ...
