NIH study: people with SARS-CoV-2 antibodies may have a low risk of future infection

People who have had evidence of a prior infection with SARS-CoV-2, the virus that causes COVID-19, appear to be well protected against being reinfected with the virus, at least for a few months, according to a newly published study from the National Cancer Institute (NCI). This finding may explain why reinfection appears […]

Treating rheumatoid arthritis with micromotors

Rheumatoid arthritis is a chronic inflammatory disorder marked by joint pain, swelling and damage. Although medications, such as steroids, anti-inflammatory drugs and immunosuppressants, can help slow joint destruction and relieve pain, they have side effects and aren’t completely successful. Now, researchers reporting in ACS’ Nano Letters have developed magnesium-based micromotors propelled by […]

Tweaking corn kernels with CRISPR

Corn—or maize—has changed over thousands of years from weedy plants that make ears with less than a dozen kernels to the cobs packed with hundreds of juicy kernels that we see on farms today. Powerful DNA-editing techniques such as CRISPR can speed up that process. Cold Spring Harbor Laboratory (CSHL) […]

Using predictive biomarkers could improve success rate of new cancer drugs

In recent decades, researchers have made big advances in developing new cancer medicines such as Herceptin, the targeted drug to treat women diagnosed with HER2-positive breast cancer. Yet, despite these successes, cancer remains the second leading cause of death after heart disease and nearly 90 per cent of all cancer drugs entering […]

"Good bacteria" in breast milk changes over time

The cocktail of beneficial bacteria passed from mother to infant through breast milk changes significantly over time and could act like a daily booster shot for infant immunity and metabolism. The research, conducted by scientists from Montreal and Guatemala and published in Frontiers in Microbiology, has important implications for infant development […]

From out of the blue comes a better bladder-cancer detector

Decades ago, blue lights helped shoppers scope out sales. Today they’re helping urologists scope out cells, specifically those of non-muscle-invasive bladder cancer. UW Medicine urologists with the Seattle Cancer Care Alliance possess a mechanism that makes the tumors glow bright pink. All the better to see them. “Seventy percent of bladder […]

Penn Scientists Discover Microbial Transplants Require Key T Cells for Success

Scientists have known for more than a decade that “good bacteria” from healthy intestines can treat and ward off potentially deadly intestinal infections by Clostridium difficile bacteria. Now researchers at the Perelman School of Medicine at the University of Pennsylvania have discovered that immune cells called Treg cells are crucial for the success […]

Fat cells may influence how the body reacts to heart failure, study shows

University of Alberta researchers have found that limiting the amount of fat the body releases into the bloodstream from fat cells during heart failure could help improve outcomes for patients. In a recent study published in the American Journal of Physiology, Jason Dyck, professor of paediatrics in the Faculty of Medicine & Dentistry and director […]

Seeing schizophrenia: X-rays shed light on neural differences, point toward treatment

An international research team used the ultrabright X-rays of the Advanced Photon Source to examine neurons in the brains of schizophrenia patients. What they learned may help neurologists treat this harmful brain disorder. Schizophrenia, a chronic, neurological brain disorder, affects millions of people around the world. It causes a fracture […]

Reactivating Aging Stem Cells in the Brain

As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked to stem cell aging – and how the production of neurons can be reactivated. […]

Stroke of Luck: Scientists Discover Target for Stroke Therapy in Blood-Brain Barrier

The blood-brain barrier prevents immune cells from circulating freely in the brain, and the breakdown of its function is a major cause of post-stroke inflammation. Now, for the first time, researchers have identified how a toxic stroke byproduct, acrolein, could activate the barrier-degrading enzyme proheparanase (proHPSE). The research group has […]
