DNA variants passed on to modern humans from Neanderthals can increase as well as decrease our ability to fight SARS-CoV-2, a new PNAS study finds. New research has found that a group of genes that reduces the risk of developing severe COVID-19 by around 20% is inherited from Neanderthals Th.
Companies that are creating rejuvenation biotechnology interventions must develop their products to target individual diseases in order to be approved by the FDA. While that is still the case, this particular FOA is intended to promote broader research that does not necessarily target individual diseases as endpoints.
The National Institutes of Aging in the United States, a component of the National Institutes of Health, is funding clinical trials for interventions that directly affect the root causes of age-related diseases.
Direct funding for trials against aging
Probably the most important and interesting part of this Funding Opportunity Announcement (FOA) is that the NIA specifically mentions “multiple chronic conditions” caused by the processes of aging along with more conventional trials that are targeted directly at specific downstream effects of aging.
Here are 8 things to know about the second dose of the vaccine. Side effects may be stronger than after the first dose, and immunity isn’t immediate.

Dwight E. Bergles, Ph.D., a leading neuroscientist at Johns Hopkins University School of Medicine, is the winner of the prestigious Barancik Prize for Innovation in MS Research. Bergles has pioneered the study of immature cells in the brain that can regenerate myelin-making cells after myelin is destroyed in MS. These cells, oligodendrocyte precursor cells (OPCs), hold the key to finding ways to promote myelin repair and restore function for people living with multiple sclerosis.
Understanding heat dissipation processes at nanoscale during cellular thermogenesis is essential to clarify the relationships between the heat and biological processes in cells and organisms. A key parameter determining the heat flux inside a cell is the local thermal conductivity, a factor poorly investigated both experimentally and theoretically. Here, using a nanoheater/nanothermometer hybrid made of a polydopamine encapsulating a fluorescent nanodiamond, we measured the intracellular thermal conductivities of HeLa and MCF-7 cells with a spatial resolution of about 200 nm. The mean values determined in these two cell lines are both 0.11 ± 0.04 W m−1 K−1, which is significantly smaller than that of water. Bayesian analysis of the data suggests there is a variation of the thermal conductivity within a cell.
Dr. Hassan A. Tetteh, MD, is the Health Mission Chief, at the Department of Defense (DoD) Joint Artificial Intelligence Center, serving to advance the objectives of the DoD AI Strategy, and improve war fighter healthcare and readiness with artificial intelligence implementations.
Dr. Tetteh is also an Associate Professor of Surgery at the Uniformed Services University of the Health Sciences, adjunct faculty at Howard University College of Medicine, a Thoracic Staff Surgeon for MedStar Health and Walter Reed National Military Medical Center, and leads a Specialized Thoracic Adapted Recovery (STAR) Team, in Washington, DC, where his research in thoracic transplantation aims to expand heart and lung recovery and save lives.
In the past, Dr. Tetteh has served as Chief Medical Informatics Officer, United States Navy, and Division Lead for Futures and Innovation at Navy Medicine’s Headquarters, a Command Surgeon for the National Defense University, and as a Robert Wood Johnson Health Policy Fellow, assigned to the U.S. Congress, Congressional Budget Office, (CBO).
Dr. Tetteh served as Ship’s Surgeon and Director of Surgical Services for the USS Carl Vinson battle group in support of Operation Iraqi Freedom, deployed as a trauma surgeon to Afghanistan’s Helmand and Nimroz provinces in support of Operation Enduring Freedom, and has supported special joint forces missions to South America, the Middle East, the South Pacific, Australia, and Africa. He earned both the Surface Warfare Medical Department Officer and Fleet Marine Force Qualified Officer designations, and his military honors include two Meritorious Service Medals and the Joint Service Commendation Medal.
