What if doctors had a remote control that they could use to steer a patient’s own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal Nano Letters have taken an important first step: They used near-infrared light and an […]Continue Reading ...
Apr 19 2019 Two papers appearing April 18 in the journal Cell Metabolism confirm that the circadian clock is an important factor in how the body responds to physical exertion. The studies focused on different components of exercise, thereby complementing each other. Based on this work alone, it’s too early to say when the best […]Continue Reading ...
Researchers have identified ketamine-induced brain-related changes that are responsible for maintaining the remission of behaviors related to depression in mice — findings that may help researchers develop interventions that promote lasting remission of depression in humans. The study, funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appears […]Continue Reading ...
Scientists at the Johns Hopkins School of Medicine have found that the drug MDMA (ecstasy) can induce a neural response referred to as a “critical period,” where the brain is sensitive to learning the reward value of social behaviors.

New studies led by University of North Carolina Lineberger Comprehensive Cancer Center researchers explore biological mechanisms behind obesity and its link with cancer. Research findings presented at the American Association for Cancer Research Annual Meeting 2019 explore possible reasons for obesity-related resistance to breast cancer treatment and possible strategies to overcome obesity-related immune suppression in […]Continue Reading ...
Credit: CC0 Public Domain Mayo Clinic researchers and their collaborators have shown that when senescent cells—also known as “zombie cells”—are removed from fat tissue in obese mice, severity of diabetes and a range of its causes or consequences decline or disappear. The findings appear in Aging Cell. Inflammation and dysfunction of fat tissue cause some […]Continue Reading ...
Changing when you eat rather than what you eat may prove to be a dietary intervention against breast cancer, suggests a new mouse study to be presented Saturday at ENDO 2019, the Endocrine Society’s annual meeting in New Orleans, La. A growing body of evidence indicates that obesity and metabolic syndrome–a collection of risk factors […]Continue Reading ...
A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say. Researchers emphasize that the study, recently published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings lend credence to […]Continue Reading ...
Two proteins that bind to stress hormones work together to maintain a healthy heart in mice, according to scientists at the National Institutes of Health and their collaborators. These proteins, stress hormone receptors known as the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), act in concert to help support heart health. When the signaling between […]Continue Reading ...
Anaesthetic drug ketamine has been recently studied in depressive illness that has not responded to standard medication. Researchers have now found the exact mechanism of how the drug works in the brains of individuals with depression and can keep the symptoms down for more than a week. The results of the study titled, “Sustained rescue […]Continue Reading ...
Stanford neuroscientist Tony Wyss-Coray, PhD, has been working for several years on the question of what causes the brain to lose its acuity with advancing age. One focus of his research has been a class of brain cells called microglia, which serve as the brain’s immune cells. A less-vaunted microglial function is more akin to […]Continue Reading ...

Symptoms of polycystic ovary syndrome (PCOS) improved with exposure to healthy bacteria in the gut, according to a study in a mouse model of this common women’s endocrine disorder. The study results will be presented Monday at ENDO 2019, the Endocrine Society’s annual meeting in New Orleans, La. This study builds on recent research by […]Continue Reading ...
Why do blood vessels naturally stiffen and degrade as we age, boosting cardiovascular disease risk? New University of Colorado Boulder research has identified a surprising new culprit–and it lives in your gut. “This is the first study to show that changes in the gut microbiome with aging have an adverse impact on vascular health,” said […]Continue Reading ...
Mar 6 2019 Dietary modifications are frequently used to treat inflammatory bowel diseases (IBDs). In new research in mice, researchers from the University of Southern California have shown that one strategy, known as the fasting-mimicking diet (FMD), changes the gut microbiota in a manner that reduces IBD pathology. The results of the murine study were […]Continue Reading ...
