Benzodiazepine Often Used in Older People Despite Risks

Benzodiazepine Often Used in Older People Despite Risks Benzodiazepines include the medications alprazolam (Xanax), diazepam (Valium), and lorazepam (Ativan). These drugs are widely prescribed to treat anxiety and sleep problems. But while effective,...

Vitamin D Levels Predict Multiple Sclerosis Progression

Vitamin D Levels Predict Multiple Sclerosis Progression Among people with early-stage multiple sclerosis (MS), those with higher blood levels of vitamin D had better outcomes during 5 years of follow-up. Identifying and correcting vitamin D insuffici...

Nature-Inspired Surgical Glue Mends Hearts

Nature-Inspired Surgical Glue Mends Hearts Researchers developed a new tissue adhesive that is biodegradable, biocompatible, and easily manipulated. It could allow for less invasive surgeries that don’t require sutures or staples. The waterproof, l...

Toxin Kills HIV-Infected Cells

Toxin Kills HIV-Infected Cells An HIV-specific poison can kill cells in which the virus is still reproducing despite antiretroviral therapy, a study in mice showed. Such targeted therapies could become a tool in strategies to combat HIV.   Electron...

Oxytocin Affects Facial Recognition

Oxytocin Affects Facial Recognition A genetic variation in the receptor for oxytocin, a hormone involved in social bonding, affects the ability to remember faces in families with a child who has autism. The finding points the way to a better understa...

Arthritis Genetics Analysis Aids Drug Discovery

Arthritis Genetics Analysis Aids Drug Discovery An international research team identified 42 new areas in the human genome associated with rheumatoid arthritis—and found that many are already the targets of drugs approved for other conditions. The...

Distracted Driving Raises Crash Risk

Distracted Driving Raises Crash Risk Researchers used video technology and in-vehicle sensors to show that distracted driving, particularly among new drivers, substantially raises the risk for car crashes and near crashes. They also found that driver...

Creative Minds: Can Microbes Influence Mental Health?

Creative Minds: Can Microbes Influence Mental Health? While sitting in microbiology class as a college sophomore, Elaine Hsiao was stunned to learn that the human gut held between as much as 6 pounds of bacteria—twice the weight of an adult human...

Insights into Brain Injury

Insights into Brain Injury New findings provide insight into the damage caused by mild traumatic brain injury and suggest approaches for reducing its harmful effects. Nationwide, at least 1.7 million traumatic brain injuries occur each year, accordin...

Study Reveals New Targets for Parkinson’s Disease

Study Reveals New Targets for Parkinson’s Disease Scientists used a novel approach to identify dozens of genes that may contribute to Parkinson’s disease. The discoveries may also yield insights into other disorders that involve mitochondria,...

Gut Microbes May Affect Cancer Treatment

Gut Microbes May Affect Cancer Treatment The effectiveness of certain cancer therapies may depend on microbes that live in the intestine, according to a study in mice. The findings suggest that antibiotics used to treat infections might hinder the ef...

Genetic Testing Doesn’t Improve Warfarin Dosing

Genetic Testing Doesn’t Improve Warfarin Dosing Adding genetic data to clinical information doesn’t improve the ability to determine initial doses of warfarin, a common blood thinner. The finding contradicts earlier studies and highlights the...

Key HIV Protein Structure Revealed

Key HIV Protein Structure Revealed Researchers have developed a more detailed picture of the protein largely responsible for enabling HIV to enter human immune cells and cause infection. The findings could help guide vaccine design. HIV, the virus th...

Gut Microbes Linked to Rheumatoid Arthritis

Gut Microbes Linked to Rheumatoid Arthritis The presence of a specific type of gut bacteria correlates with rheumatoid arthritis in newly diagnosed, untreated people. The finding suggests a potential role for the bacteria in this autoimmune disease.

Eye Contact Declines in Young Infants with Autism

Eye Contact Declines in Young Infants with Autism Beginning as young as 2 months of age, infants later diagnosed with autism show a steady decline in eye contact that might be the earliest marker yet for the disorder. If confirmed, the finding might...
