Lubricant Shots for Knee OA: No, They Really Don’t Help
Researchers analyzing previous trials of hyaluronic acid injections for knee osteoarthritis (OA) found that, although measurable benefit was demonstrated, it was too small to be clinically relevant. Pooled data from 24 large placebo-controlled studies comprising a total of 8,997 participants with knee OA indicated that, relative to placebo injections, hyaluronic acid reduced patients’ pain with […]
Researchers expand understanding of vortex spread in superfluids
An international team of scientists featuring Florida State University researchers has developed a model that predicts the spread of vortices in so-called superfluids, work that provides new insight into the physics that govern turbulence in quantum fluid systems such as superfluid neutron stars. In a paper published in Physical Review Letters, the researchers created a […]
Researchers discover new leukemia-killing compounds: Potential of mitochondria-targeted chemotherapies
Researchers from Rice University and the University of Texas MD Anderson Cancer Center have discovered potential new drugs that work in concert with other drugs to deliver a deadly one-two punch to leukemia. The potential drugs are still years away from being tested in cancer patients, but a recently published study in the journal Leukemia […]
No more binge eating: Signal pathway in the brain that controls food intake discovered
A group of researchers has developed an entirely novel approach to treating eating disorders. The scientists showed that a group of nerve cells in the hypothalamus (so-called AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, which stimulates food intake. In […]
Microbe protects honey bees from poor nutrition, a significant cause of colony loss
Indiana University researchers have identified a specific bacterial microbe that, when fed to honey bee larvae, can reduce the effects of nutritional stress on developing bees — one of the leading causes of honey bee decline. Their findings were recently published in the International Society for Microbial Ecology Journal. Humans rely on honey bees for […]
As US obesity epidemic grows, new study shows who is gaining weight over the last decade
Newly published research from BYU exercise science researchers reveals critical, rare data detailing the severity of the obesity epidemic in the United States. The article, published in the Journal of Obesity, looked at the long-term weight gain of more than 13,800 U.S. adults — a rare data point unearthed in obesity research. They found that […]
A rare discovery of long-term memory in wild frog-eating bats: 4 years after first exposure, bats remember a ringtone’s link to food
Frog-eating bats trained by researchers to associate a phone ringtone with a tasty treat were able to remember what they learned for up to four years in the wild, new research has found. The study acquainted 49 bats with a series of ringtones that attracted their attention, and trained them to associate flying toward just […]
E-Scooters in Tucson, AZ: Modeling placement, charging, and rebalancing
Are e-scooters just the first sign of a shared-mobility revolution? If they are, then researchers at the University of Arizona intend to make sure that the emerging transportation system has functional models on par with other modes of transportation. In 2018, approximately 100 U.S. cities had already launched shared e-scooter programs, accounting for 38.5 million […]
The benefits of exercise in a pill? Science is closer to that goal
Researchers at Baylor College of Medicine, Stanford School of Medicine and collaborating institutions report today in the journal Nature that they have identified a molecule in the blood that is produced during exercise and can effectively reduce food intake and obesity in mice. The findings improve our understanding of the physiological processes that underlie the […]
Could used beer yeast be the solution to heavy metal contamination in water? A study shows that yeast, an abundant waste product from breweries, can filter out even trace amounts of lead
A new analysis by researchers at MIT’s Center for Bits and Atoms (CBA) has found that inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The study shows that this approach can be efficient and economic, even down to part-per-billion levels of contamination. Serious […]
