Phys.org / Stellar stream beyond Milky Way offers new tool to map dark matter
In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history ...
Medical Xpress / Silent Strep A infections may explain immunity gained by adulthood
Exposure to Streptococcus pyogenes (Strep A) that causes mild or no symptoms can trigger the body's immune response and naturally build protection, potentially solving a nearly 100-year-old mystery of immunity.
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.
Phys.org / Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices
Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing ...
Phys.org / Sugar molecule could help protect against dangerous hospital fungus Candida auris
Researchers have developed a potential new approach against the highly drug-resistant hospital fungus Candida auris. They discovered that a synthetic sugar molecule that is a natural part of the fungus's cell wall, but is ...
Medical Xpress / Taking the stairs could cut risk of early death
Taking the stairs could help you live longer—according to new research from the University of East Anglia and the Norfolk and Norwich University Hospital. The study, published today, suggests that climbing stairs significantly ...
Medical Xpress / Can a vaccine built for one Ebola virus stop another? The World Health Organization is about to find out
The World Health Organization (WHO) has recommended prioritizing the Ervebo vaccine for testing in a clinical trial in the Democratic Republic of the Congo. The vaccine was originally developed to protect against Zaire ebolavirus, ...
Medical Xpress / Poison center reports of liver injuries rise nearly 400% since 2000, with acetaminophen as a top driver
Calls to poison centers involving liver injuries caused by medications, supplements, alcohol and other substances jumped nearly 400% between 2000 and 2024, according to a new study from UVA Health published in Clinical Gastroenterology ...
Phys.org / Swarms of tiny robots remove microplastics from soil and water
Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move ...
Phys.org / Four hazards converge in East Portland, where underinvestment deepens vulnerability
When it comes to compounding natural hazards like landslides, wildfires, flooding and extreme heat, where you live makes all the difference. New research from Portland State University underscores this disproportionate reality, ...
Phys.org / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Medical Xpress / Appetite-suppressing hormone may protect liver from inflammation through newly discovered signaling pathway
Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown ...
