Researchers study if nerve cells evolved to talk to microbes

Various diseases of the digestive tract, for example severe intestinal inflammation in humans, are closely linked to disturbances in the natural mobility of the intestine. What role the microbiome—i.e. the natural microbial community colonizing the digestive tract—plays in these rhythmic contractions of the intestine, also known as peristalsis, is currently the subject of intensive research.

The Secrets to Losing Weight After 40

In your teens and 20s, it used to be that you could eat pizza every night for a week without a lot of pushback from your body in the form of extra pounds. In your 40s, not so much. Maybe you’re even eating much better now, but weight is still accumulating. It’s usually not just

Tracking mobility of individuals offers clues to finding COVID

Harvard scientists are leading a global research network that is using data from mobile devices and social media to document people’s movements during the COVID-19 outbreak and translate that information to help government officials set pandemic policy worldwide. The effort, called the COVID-19 Mobility Data Network, involves about 60 academic research labs working with officials

Prescription monitoring may curb inappropriate drug use, but what happens to those denied a script?

Restricting access to high-risk medications via a real-time prescription monitoring program such as Victoria’s SafeScript may help reduce inappropriate use, but integrated mental health and drug treatment services may be necessary to offset the risk of increased mortality, according to the authors of a letter published online by the Medical Journal of Australia. Researchers from

Study ties blood type to COVID-19 risk; O may help, A hurt

A genetic analysis of COVID-19 patients suggests that blood type might influence whether someone develops severe disease. Scientists who compared the genes of thousands of patients in Europe found that those who had Type A blood were more likely to have severe disease while those with Type O were less likely. Wednesday’s report in the

Nation’s capital could move to phase 2 reopening next week

Washington, D.C., officials are targeting next Monday for the start of phase two of reopening the nation’s capital after months of social restrictions due to the COVID-19 pandemic. Mayor Muriel Bowser said Wednesday that she would make a final decision and announcement on Friday. But if the numbers continue “trending in the right direction,” Bowser

National tick surveillance survey identifies gaps to be filled

New Cornell-led research shows that inadequate funding is the main barrier to better surveillance and control of ticks, including the blacklegged tick, which spreads Lyme disease, the No. 1 vector-borne illness in the country. Insufficient infrastructure, limited guidance on best practices and lack of institutional capacity also are impediments to improved tick monitoring, the researchers

Study underlines importance of adequate PPE and training to prevent COVID-19 infection

Despite being at high risk of exposure to COVID-19, frontline healthcare professionals who were appropriately protected did not contract infection or develop protective immunity against the virus, finds a study from China published by The BMJ today. The researchers acknowledge that the healthcare professionals were working away from home, so had limited social interactions after

COVID-19 loneliness linked to elevated psychiatric symptoms in older adults

Although social distancing is crucial in thwarting the spread of COVID-19, isolation and the ensuing loneliness may be severely detrimental for older adults. A new study conducted by researchers at Bar-Ilan University and the University of Haifa has linked COVID-19-based loneliness in older adults with elevated psychiatric symptoms of anxiety, depression, and trauma symptoms that

Clock-controlled chemokine contributes to neuroinflammation-induced depression

Depression is a mental disorder with complex gene-environment interactions. Previous studies have suggested circadian factors play a crucial role in the etiology of depression. Moreover, there is a growing body of evidence supporting neuroinflammation is an important factor involving the pathology of depression. More interestingly, microglia as the main executor of immune function in the
