Phys.org / The best places to look for alien life: Scientists identify 45 Earth-like worlds to explore for a 'Project Hail Mary'
If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look for it. They have identified just under 50 rocky worlds most likely to be habitable out of the more than 6,000 exoplanets ...
Phys.org / Changing leafcutter ants' food reshapes their microbial gardens, scientists find
A colony of leafcutter ants is home to more than just one species. Each year, studies reveal new layers of complexity in these ecosystems, where various fungi and bacteria thrive alongside the ants, resulting in countless ...
Medical Xpress / Newly-discovered dopamine signal may help the brain steer us in the right direction
A Boston University-led research team has discovered a dopamine signal in the brain that helps determine whether you are moving toward or away from a goal, potentially shedding new light on how the brain uses visual information ...
Phys.org / 'Mini earthquakes' turn tiny chips into radio signal powerhouses
From GPS satellites to mobile networks, modern technology relies on ultra-precise radio signals. Engineers have long tried to generate them on chips using interactions between light and sound, but the effect was too weak. ...
Medical Xpress / High meat consumption linked to lower dementia risk in APOE4 carriers
Older people with a genetic risk of Alzheimer's disease did not experience the expected increase in cognitive decline and dementia risk if they consumed relatively large amounts of meat. This is shown in a new study from ...
Medical Xpress / New 'fishhook' bonds help T cells stick longer to prostate cancer cells
UCLA and Stanford Medicine researchers, in collaboration with scientists from the University of Utah and Columbia University, have engineered a new class of supercharged T cells that are stronger, longer-lasting, and more ...
Medical Xpress / Smartwatch and blood test data combine to better predict insulin resistance and diabetes
Around 20–40% of the general population are estimated to have insulin resistance—a condition where insulin begins to be less effective in the body, and glucose regulation becomes more difficult. Eventually, this can lead ...
Medical Xpress / Researchers launch OZ-ABCD tool to curb medication harm in aged care
Researchers at Monash University, together with a multidisciplinary team of health care professionals and medication safety experts, have developed the first national consensus list of medicines with a high risk of harm in ...
Phys.org / Sweden's 'old‑growth' natural forests store 83% more carbon than managed woodlands—new study
Most of Europe's original natural forests have been transformed for agriculture and managed forests producing energy, paper, and timber. The few remaining "old-growth" natural forests are relics of the past that illustrate ...
Tech Xplore / Smarter, faster, and more human: AI system helps robots outpace their human teachers
Robots are increasingly learning new skills by watching people. From folding laundry to handling food, many real-world, humanlike tasks are too nuanced to be efficiently programmed step by step.
Phys.org / NASA's Hubble unexpectedly catches comet breaking up
In a happy twist of fate, NASA's Hubble Space Telescope witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings are published in the journal ...
Phys.org / A multi-lane highway for light: Topology helps build more robust photonic networks
Penn-led researchers have shown for the first time that multiple, information-carrying light signals can be safely guided through chip-based, reconfigurable networks using topology, the esoteric branch of mathematics that ...
