Medical Xpress / Exhaled breath may carry clues to gut microbiome health
The human gut is home to trillions of beneficial microbes that play a crucial role in health. Disruptions in this delicate community of bacteria and viruses—called the gut microbiome—have been linked to obesity, asthma ...
Phys.org / Massive cloud with metallic winds discovered orbiting mystery object
Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile, one half of the International Gemini ...
Phys.org / Key protein can restore aging neural stem cells' ability to regenerate
Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have found that a key protein can help to regenerate neural stem cells, which may improve aging-associated decline in neuronal ...
Medical Xpress / Omitting Medicare data skews hospital readmission penalties, study shows
For more than a decade, hospitals have worked to help older adults avoid repeated inpatient stays, incentivized by a federal program that cuts Medicare reimbursements if hospitals have higher-than-expected rates of readmissions ...
Medical Xpress / Chemotherapy rewires gut bacteria to curb metastasis, research reveals
Chemotherapy commonly damages the intestinal lining, a well-known side effect. But this injury does not remain confined to the gut. It reshapes nutrient availability for intestinal bacteria, forcing the microbiota to adapt.
Phys.org / Prehistoric tool made from elephant bone is the oldest discovered in Europe
A remarkable prehistoric hammer made from elephant bone, dating back nearly half a million years ago, has been uncovered in southern England and analyzed by archaeologists from UCL and the Natural History Museum, London.
Phys.org / Ancient Mesopotamian medical texts reveal the role of divine sanctuaries in treating ear and spleen ailments
In a study published in the journal Iraq, Dr. Troels Arbøll analyzed medical prescriptions from ancient Mesopotamia to understand and re-evaluate the role sanctuaries played in the healing process. The study found that specific ...
Phys.org / Bird retinas function without oxygen—solving a centuries-old biological mystery
Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future treatment of stroke patients.
Medical Xpress / Unexpected vitamin B1 connection emerges in genetic study of gut motility
Bowel habits aren't exactly dinner-table talk. But they reflect how quickly the gut moves things along, and when that goes wrong, people can experience constipation, diarrhea, or irritable bowel syndrome (IBS). Yet the biological ...
