More infectious COVID-19 variants are spreading in the U.S. at the same time as cases are falling and the national vaccination campaign is picking up steam. Put it all together, a Harvard epidemiologist said Friday, and it may all add up to a lucky break for us, and we may […]
Researchers from Skoltech and the University of Texas at Austin have presented a proof of concept for a wearable sensor that can track healing in sores, ulcers and other kinds of chronic skin wounds, even without the need to remove the bandages. The paper was published in the journal ACS […]
Astrocytes—star-shaped cells in the brain that are actively involved in brain function—may play an important role in stuttering, a study led by a University of California, Riverside, expert on stuttering has found. “Our study suggests that treatment with the medication risperidone leads to increased activity of the striatum in persons […]
A process that releases iron in response to stress may contribute to heart failure, and blocking this process could be a way of protecting the heart, suggests a study in mice published today in eLife. People with heart failure often have an iron deficiency, leading some scientists to suspect that […]

A mathematical model that can help project the contagiousness and spread of infectious diseases like the seasonal flu may not be the best way to predict the continuing spread of the novel coronavirus, especially during lockdowns that alter the normal mix of the population, researchers report. Called the R-naught, or […]
Researchers at the University of Colorado Anschutz Medical Campus have discovered that fructose stimulates the release of vasopressin, a hormone linked to obesity and diabetes. They also found that water can suppress the hormone and alleviate these conditions in mice. “The clinical significance of this work is that it may […]
Early circulating tumor cell dynamics were associated with overall survival in patients with metastatic breast cancer, according to a meta-analysis presented at the 2020 San Antonio Breast Cancer Symposium, held Dec. 8-11. “With the increasing number of treatment options available to patients with metastatic breast cancer, being able to predict […]
Scientists said Monday they had developed a way of predicting if patients will develop Alzheimer’s disease by analysing their blood, in what experts hailed as a potential “gamechanger” in the fight against the debilitating condition. Around 50 million people live with Alzheimer’s, a degenerative brain disease that accounts for more […]
