Phys.org / If alien signals have already reached Earth, why haven't we seen them?
For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically ...
Medical Xpress / Can you spot an AI face? A new test shows why some people do better
Can you tell the difference between an artificial-intelligence-generated face and a real one? In an era of digital misinformation, where fabricated images can spread widely across news and social media, this skill is proving ...
Phys.org / Does vegan-friendly haircare work? Early tests show shinier, easier-to-comb strands
To find new ways to shield hair from heat, sunlight and air pollution, researchers in Brazil are turning to vegan-friendly ingredients for shampoos and conditioners. Published in ACS Omega, early tests show that a fruit-algae ...
Phys.org / Slippery ions create a smoother path to blue energy
Osmotic energy, often called blue energy, is a promising way to generate sustainable electricity from the natural mixing of salt and fresh water. It exploits the voltage that arises when ions from saltwater pass through an ...
Medical Xpress / IBD study tracks 54,000 patients, links dysplasia grade to cancer risk
Precancerous colorectal lesions, or dysplasia, in patients with inflammatory bowel disease (IBD) confer markedly different risks of future colorectal cancer depending on dysplasia grade, according to a comprehensive registry ...
Phys.org / Report: Women remain underrepresented in scientific organizations
Women account for a growing share of the global scientific workforce (31.1% of researchers worldwide in 2022, according to UNESCO), yet they remain underrepresented in the organizations that shape scientific recognition, ...
Medical Xpress / Study finds fewer overdose deaths among needle and syringe program participants
A recently published study from Karolinska Institutet shows that mortality among people who inject drugs enrolled in the Stockholm needle and syringe program declined over a 10-year period, with a marked reduction in opioid ...
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Medical Xpress / Dual brakes on T-cells: New targets found to boost immunity in chronic infections
Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve treatments to control chronic ...
Phys.org / Greenland's west coast posts warmest January on record
Greenland's capital Nuuk registered its warmest ever January—beating a record that stood for 109 years—as temperatures soared across the Arctic island's west coast, the Danish Meteorological Institute said Monday.
Phys.org / A new concept for catching up with 3I/ATLAS
The arrival of 3I/ATLAS in our solar system spawned multiple proposals for a rendezvous mission to study it up close. As the third interstellar object (ISO) ever detected, the wealth of information direct studies could provide ...
Phys.org / Teaching the human skills AI can't replace
New Edith Cowan University (ECU) research suggests emotional literacy may be one of the most important skills students can learn, not just for relationships, but for their education and future careers.
