- Artificial intelligence tool to improve heart failure care May 14, 2024The powerful new AI tool can predict heart failure outcomes in specific patients, helping doctors improve care.
- People without an inner voice have poorer verbal memory May 14, 2024The vast majority of people have an ongoing conversation with themselves, an inner voice, that plays an important role in their daily lives. But between 5-10 per cent of the population do not have the same experience of an inner voice, and they find it more difficult to perform certain verbal memory tasks, new research […]
- Some brain cells age faster and are more prevalent in Alzheimer's May 14, 2024Engineers have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer's disease. Additionally, researchers observed male-female-specific differences in the aging process of certain brain cells, with the female cortex exhibiting a higher ratio of 'old' oligodendrocytes to 'old' neurons compared to the male cortex. […]
- People with more copies of ribosomal DNA may have higher risks of developing disease May 14, 2024Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more copies of rDNA are more likely to develop inflammation and diseases during their lifetimes.
- Distinct population of 'troublemaker' platelet cells appear with aging, lead to blood clotting, disease May 14, 2024Researchers have discovered a distinct, secondary population of platelets that appears with aging and have hyperreactive behavior and unique molecular properties, which could make them easier to target with medication.
- Mixed public opinion on polygenic embryo screening for IVF May 14, 2024Survey reveals nearly three-quarters of U.S. adults support using emerging technology to screen embryos during IVF for risk of developing certain health conditions or traits that arise from more than one gene. Only about one-third of respondents approved of using the technology to predict traits unrelated to disease. Nearly all expressed concerns about potential negative […]
- Innovative 'mini-brains' could revolutionize Alzheimer's treatment May 14, 2024New research could revolutionize the way Alzheimer's and other brain-related diseases are diagnosed and treated -- by building tiny brains in a petri dish.
- First case of highly pathogenic avian influenza transmitted from cow to human confirmed May 13, 2024in March a farm worker who reported no contact with sick or dead birds, but who was in contact with dairy cattle, began showing symptoms in the eye and samples were collected by the regional health department to test for potential influenza A. Experts have now confirmed the first case of highly pathogenic avian influenza […]
- Persistent strain of cholera defends itself against forces of change, scientists find May 13, 2024A longstanding mystery about the strain of Vibrio cholerae (V. cholerae) responsible for the seventh global cholera pandemic is how this lineage has managed to out-compete other pathogenic variants. The team identified a unique quirk of the immune system that protects the bacteria from a key driver of bacterial evolution.
