The time of day when blood is taken can affect the results of tests for diagnosing dementia, according to new research. The time of day when blood is taken can affect the results of tests for diagnosing dementia, according to new research led by the University of Surrey. Researchers found that the biomarkers used to

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the nucleus' could open new possibilities in gene therapy, where genetic material needs to be delivered directly into the nucleus, as well

Researchers have found a potential new way to improve the treatment of multiple sclerosis (MS) using a novel combined therapy. The results build on two harmonized Phase I clinical trials, focusing on the use of Vitamin D3 tolerogenic dendritic cells (VitD3-tolDCs) to regulate the immune response in MS patients. The team is now preparing to

People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low -- from taking too much insulin or not eating enough sugar -- people can experience hypoglycemia, which can lead to dizziness, cognitive impairment, seizures or comas. To prevent and treat this condition, researchers report encapsulating the hormone glucagon.

It's important to eat your veggies, but some essential vitamins and nutrients can only be found in animals, including certain amino acids and peptides. But, in a proof-of-concept study, researchers developed a method to produce creatine, carnosine and taurine -- all animal-based nutrients and common workout supplements -- right inside a plant. The system allows

Researchers collected archival data on more than 3.4 million people living in the United States and United Kingdom. They found evidence that obesity tends to spur lighter medical and psychological harms when those who struggle with the disorder feel less conspicuous. Individuals struggling with obesity face a number of social and health difficulties, but those

Researchers discovered a mechanism by which estrogen can trigger fast neuronal responses. Estrogen, the major female ovarian hormone, can trigger nerve impulses within milliseconds to regulate a variety of physiological processes. At Baylor College of Medicine, Louisiana State University and collaborating institutions, researchers discovered that estrogen's fast actions are mediated by the coupling of the

Despite growing evidence of the importance of student well-being and an abundance of best practices, most institutions have yet to prioritize it as much as they do enrollment, graduation and grades. A new study provides guidance on how institutions can support and enhance student well-being, and breaks down the various benefits for learners during and

A common mutation in the KRAS gene is associated with improved overall survival in pancreatic ductal adenocarcinoma (PDAC) compared with other variants, in part because the mutation appears to lead to less invasiveness and weaker biological activity, according to a multicenter study. A common mutation in the KRAS gene is associated with improved overall survival

Ever wish you could stop that fruit fly on your kitchen counter in its tracks? Scientists have created flies that halt under red light. In doing so, they discovered the precise neural mechanisms involved in stopping. Their findings, published this week in Nature, have implications far beyond controlling fly behavior. They demonstrate how the brain

A small clinical trial has found that at low doses, lithium aspartate is ineffective in treating the fatigue and brain fog that is often a persistent feature of long COVID. A small University at Buffalo clinical trial has found that at low doses, lithium aspartate is ineffective in treating the fatigue and brain fog that

'Future You' is a generative AI tool that enables users to have a simulated conversation with a potential version of their future selves. The chatbot is meant to reduce users' anxiety, improve positive emotions, and guide them toward making better everyday choices. Have you ever wanted to travel through time to see what your future
