Phys.org / 'Super-puff' planets less dense than cotton candy discovered by international team
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration ...
Medical Xpress / Researchers develop HIV-prevention guide without the stigma of asking about risk
The most useful thing about a new HIV prevention guide may be a question it never asks: Why do you want to know about pre-exposure prophylaxis, or PrEP? In a pilot study at three clinics, a two-page decision aid helped people ...
Phys.org / Tiny water droplets transmutate aniline into pyridine in ambient and catalyst-free conditions
Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving ...
Phys.org / Binary black hole signal probes event horizon region for first time
If, in space, no one can hear you scream, it seems that you can actually hear the sound of a crash when two black holes collide. Using the loudest gravitational wave ever heard, two Australian scientists and colleagues have ...
Phys.org / Oxygen atoms in 15‑million‑year‑old giant eggshells reveal how plants reacted to a hotter Earth
Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene ...
Medical Xpress / Top supplements Americans use are shifting from multivitamins to targeted health fixes
Dietary supplements are an excellent way to fill gaps in our nutritional requirements. From vitamins and macronutrients to gut-health probiotics, dietary supplements have helped people address deficiencies. In recent years, ...

A new study analyzing more than 11,000 YouTube videos and comments found that online narratives surrounding avian influenza evolved alongside major outbreak developments, including increasing reports of infections in mammals, ...
Medical Xpress / Hospital AI tool predicts low blood sugar in patients up to 24 hours in advance
Cedars-Sinai Health Sciences University investigators developed an AI-based model that can identify hospitalized patients at risk of low blood sugar up to 24 hours before the condition occurs. The long short-term memory (LSTM) ...
Medical Xpress / Poor metabolic health can age the brain even in young people, finds new large-scale study
Two people of very different ages can have a similar level of biological aging in their brains. Such an occurrence is possible because aging and metabolic health follow two distinct pathways that influence brain health. While ...
Phys.org / Better unemployment welfare could curb rise of populism
The study, by researchers Chase Foster (King's College London) and Jeffry Frieden (Columbia University), analyzed 134 national elections in 16 countries between 1990 and 2021, alongside data from 11 waves of the European ...
Phys.org / Evidence identifies ancient Aboriginal mining in the Riverland
Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's ...
Phys.org / How long can plants survive on Earth? New model suggests up to 2 billion more years
Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...
