Phys.org / Chemical fingerprints reveal hidden binary pasts of massive stars
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...
Phys.org / Californians are twice as likely as Louisianans to be childfree—but demographics tell more of the story
Across the United States, the number of people who do not have and do not want to have children is growing. While they are twice as likely to live in California as Louisiana, individual demographic characteristics are the ...
Tech Xplore / Butterfly-inspired ceramic microscrolls unroll with magnets to power tiny robots
Researchers at the University of Stuttgart and the Max Planck Institute for Solid State Research have developed tiny rolls that can be unrolled and rolled up in a controlled manner using a magnet. The model for this was the ...
Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Tech Xplore / Electrochemical method could make seawater a low-cost source of magnesium salts
Magnesium supplements are gaining popularity to treat conditions such as insomnia, migraines and constipation. Most magnesium salts are extracted from rocks by crushing and heating them, which requires a lot of energy. Now, ...
Medical Xpress / WHO says Congo's Ebola outbreak is on track to surpass the deadliest one in history
The ongoing Ebola outbreak in Congo is on track to surpass the deadliest one in history that killed over 11,000 people, the head of the World Health Organization said Wednesday.
Phys.org / Late Paleozoic Ice Age warming event hints at potential climate 'tipping point'
Researchers say a spike in temperatures during an ice age 304 million years ago could inform what climate scientists are learning about rapidly changing conditions today.
Tech Xplore / Extreme space weather could disrupt flights and expose passengers to high radiation, study warns
Researchers at the Surrey Space Centre (SCC) found that extreme space weather events can significantly increase radiation exposure at typical flight altitudes of 8–14 km (5–9 miles) and trigger faults in aircraft electronics—posing ...
Phys.org / Immune 'reprogramming' could protect poultry from deadly diseases without antibiotics
University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. ...
Phys.org / Rangers and scientists map vulnerable reefs in the remote Groote Archipelago
For thousands of years, the Anindilyakwa people have lived in deep connection with the waters surrounding Groote Eylandt, a remote island in the Gulf of Carpentaria.
Medical Xpress / Sleep could help identify people at risk of developing Alzheimer's disease at an earlier stage
What if certain signs of the disease were to manifest subtly during sleep, long before the first memory problems appear? This is the line of inquiry being explored by a team of researchers at ULiège.
Medical Xpress / Finding a tumor's soft spot to power-up immunotherapy
Researchers at the USC Viterbi School of Engineering and Keck School of Medicine of USC have engineered a genetic tool that addresses one of the most persistent obstacles in cancer immunotherapy: the physical softness of ...
