New research reveals how neurons in a fly's brain signal the direction in which the body is traveling. The cells appear to literally perform vector math in order to act as a biological compass.
Epidermal stem cells that hail from the hair follicle retain memories of their journey to the skin's surface. Those memories are a boon for wound repair, but may also contribute to chronic diseases and cancer.
Human cells can be coaxed into preventing certain enveloped viruses (including HIV, Ebola, and parainfluenza) from escaping their membranes in the lab, a finding that could lead to novel treatments for many viral diseases.
A new study finds that proteins known as linker histones control the complex coiling process that determines whether DNA will wind into long and thin chromosomes, made up of many small loops, or short and thick chromosomes with fewer large loops.
Studying dozens of naturally occurring and laboratory-selected mutations in SARS-CoV-2, researchers found that the virus will need to pull off a genetic feat to become fully resistant to antibodies.
If COVID-19 lockdowns scrambled your sleep schedule and stretched your waistline, you're not alone. Fruit flies quarantined in test tubes sleep too little and eat too much after only one week of social isolation.
Cohen, a physician-scientist exploring obesity and metabolic disease, has conducted groundbreaking research on the complex inner workings of fat tissue.
