Flies sleep when need arises to adapt to new situations

Flies that cannot take to the air respond by sleeping more as they learn to adapt to their flightlessness, according to a study from Washington University School of Medicine in St. Louis. The findings, published May 8 in Science Advances, suggest that sleep may be an evolutionary tool that helps animals adapt to challenging new situations. “We know that sleep […]

Insight into Alzheimer’s early stages provides clues to treatment strategies

Alzheimer’s disease is the most common form of dementia, affecting more than 5 million people in the U.S., but doctors have limited advice on how to protect against it. The disease develops silently in the brain for two decades or more before people begin showing the characteristic signs of forgetfulness and confusion. Understanding that silent phase could be key to […]

Proteins that protect against joint inflammation identified

Endogenous proteins that play a vital part in allergies and parasitic infection can prevent the immune system from wrongly attacking the body and causing inflamed joints, a study from Karolinska Institutet in Sweden published in the scientific journal PNAS reports. The researchers hope that the results will give rise to new drugs for rheumatoid arthritis. In protecting us against infections, […]

Blue light triggers memory and emphatic fear in mice via noninvasive approach

Researchers at the Center for Cognition and Sociality, within the Institute for Basic Science (IBS) in South Korea, have engineered an improved biological tool that controls calcium (Ca2+) levels in the brain via blue light. Published in Nature Communications, this optogenetic construct, called monster-OptoSTIM1 or monSTIM1 for short, causes a change in mice’s fear learning behavior without the need of […]

Select few cancer patients enroll in potentially life-extending clinical trials

Patient enrollment in clinical trials as the first course of treatment after cancer diagnosis is low, despite the fact that enrollment may increase life expectancy, according to researchers at Penn State. They also found that white males with private health insurance and metastatic cancers treated at academic medical centers are more likely than other groups to enroll in clinical trials. […]

New species of antibiotic-resistant bacteria found in infected wound

A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species—the first of the new genus—is Scandinavium goeteborgense, after the city of Gothenburg, where the bacterium was isolated and the research was done. Knowing which bacteria cause infections and which antibiotics […]

New research could reduce the risk of sudden cardiac death

Around 26 million people worldwide suffer from heart failure, with more than 50 per cent dying suddenly most likely due to the spontaneous onset of a heart rhythm problem, known as an arrhythmia. The link between the electrical signal that triggers the heart cell to contract (action potential) and consequent ability of the heart to pump blood has been known […]

Research suggests expanding amblyopia treatment approaches

When University of California, Irvine neurobiologist Carey Y.L. Huh, Ph.D., set her sights on discovering more about amblyopia, she brought personal insight to her quest. As a child, Huh was diagnosed with the condition, which is often called “lazy eye.” Huh is a researcher in the lab of UCI associate professor of neurobiology & behavior Sunil Gandhi. She and her […]
