Phys.org / To measure a black hole's ultimate spin, we have to go to space
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding ...
Medical Xpress / Study identifies patients with obesity most likely to benefit from GLP-1-based treatment
Why do some people lose substantial weight with GLP-1-based medications while others see more modest results? A Mayo Clinic study offers a potential answer by identifying a distinct biological subtype of obesity that responds ...
Phys.org / Cast away: Tracing the voyage of a plastic bottle cap and its hitchhiking marine species
Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells and ocean current simulations. They found 307 organisms, ...
Phys.org / Climate change leaves northern tree swallows more vulnerable than those in the southern US
Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S., according to a new study led by Cornell researchers ...
Phys.org / Bio-metal: Exploring the metallic mystery of an ancient maw
When playing the classic game "20 Questions," one may begin with the common opener: "Animal, vegetable, or mineral?"
Phys.org / New cell imaging method shines a light on blind spots
Cells are crowded, dynamic places where thousands of molecules interact in tight quarters. Until now, scientists lacked a reliable way to see many of these molecular interactions as they happen. Researchers at the University ...
Medical Xpress / New images map key membrane protein in brain related to stroke
Scientists have, for the first time, mapped in exquisite three-dimensional detail six major conformations of a membrane in the brain related to learning, memory and fear-related behavior.

Phys.org / Distant exoplanets may be hiding water beyond Webb Telescope's reach, study finds
The planets that appear most common in the universe could have a lot of water—but it could be hiding where telescopes can't detect it, according to a new study led by scientists with the University of Chicago.
Phys.org / How NASA's Artemis III lander test will pave way for moon landings
Before Artemis astronauts land on the moon's surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial ...
Tech Xplore / Sun-tracking solar panels fold away from hail while lifting output nearly 40%
Researchers led by Armin Buchroithner from the Institute of Electrical Measurement and Sensor Systems at TU Graz have developed an innovative photovoltaic system that combines significantly higher output with protection from ...
