Phys.org / Whales may divide resources to co-exist under pressures from climate change
The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
Medical Xpress / Dietary supplement may protect against inflammation-related injury and death by enhancing kidney function
As soon as you are wounded—whether from grabbing a hot pan or contracting the flu—you begin a unique journey through variable symptoms toward either recovery or death. This journey is called your disease trajectory, and ...
Phys.org / Hubble uncovers the secret of blue straggler stars that defy aging
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...
Phys.org / Neanderthals took reusable toolkits with them on high-altitude treks through the Alps
When Neanderthals in Italy were crossing the Alps, it's likely they took refuge in high-altitude bear caves. A new study of stone tools in Caverna Generosa, a cave sitting 1,450 meters up in the mountains, found that these ...
Phys.org / Ancient giant kangaroos could hop to it when they needed to, hindlimb study suggests
Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, according to research published in Scientific Reports.
Tech Xplore / Engineers invent wireless transceiver that rivals fiber-optic speed
A new transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 140-gigahertz territory, unlocking data speeds that rival those of physical fiber-optic cables and laying ...
Tech Xplore / Creative talent: Has AI knocked humans out?
Are generative artificial intelligence systems such as ChatGPT truly creative? A research team led by Professor Karim Jerbi from the Department of Psychology at the Université de Montréal, and including AI pioneer Yoshua ...
Phys.org / Biofilm streamers harden under flow, making bacterial infections harder to treat
Whether in the human body or on surfaces, bacteria protect themselves from outside attackers using biofilms. Physicist Eleonora Secchi is researching how these slime-like protective films are formed, with the aim of making ...
Phys.org / Too much entanglement? Quantum networks can suffer from 'selfish routing,' study shows
Quantum technologies, systems that process, transfer or store information leveraging quantum mechanical effects, could tackle some real-world problems faster and more effectively than their classical counterparts. In recent ...
Phys.org / Human penis size influences female attraction and male assessment of rivals, study suggests
Men assess potential rivals that have a larger penis as more of a threat, both physically and sexually, according to a study by Upama Aich at the University of Western Australia and colleagues, published in PLOS Biology.
Phys.org / New code connects microscopic insights to the macroscopic world
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches ...
Phys.org / Chimpanzees are better at solving resource dilemmas in larger, more tolerant groups
Despite being one of the most cooperative species on the planet, humans routinely fail to manage shared resources sustainably. We overfish from the oceans, burn fossil fuels, and over-prescribe antibiotics; behaviors that ...
