Einstein researchers use novel approach to uncover genetic components of aging

Scientists at Einstein College of Medicine have discovered the secret behind people living to 100 or more: favorable “longevity” genes that protect against disease-causing genes. The novel method used by researchers could lead to new drugs to protect against age-related diseases, including cardiovascular disease and diabetes.

Monkeys use 'baby talk' to interact with infants

Researchers found that rhesus macaques increase grunts and girneys when interacting with babies, suggesting a way for females to elicit attention and encourage behavior in infants. These vocalizations may also facilitate interactions between females with babies, promoting social tolerance.

Software coordinates 19 mirrors, focuses James Webb Space Telescope

Scientists have developed algorithms to enable the 19 individual mirrors of NASA's James Webb Space Telescope to function as one telescope, allowing for sharper images and detection of distant galaxies. The 'Wavefront Sensing and Controls' system was tested successfully on a scale model and through computer simulations.
