Algorithm Personalizes Which Cancer Mutations Are Best Targets for Immunotherapy

As tumor cells multiply, they often spawn tens of thousands of genetic mutations. Figuring out which ones are the most promising to target with immunotherapy is like finding a few needles in a haystack. Now a new model developed by researchers in the Abramson Cancer Center at the University of Pennsylvania hand-picks […]

Scientists discover skin keeps time independent of the brain

Squids, octopuses, cuttlefish, amphibians, and chameleon lizards are among the animals that can change the color of their skin in a blink of an eye.  They have photoreceptors in their skin that operate independently of their brains. The photoreceptors are part of a family of proteins known as opsins. Mammals […]

Study focuses on repair and reversal of damage caused by Huntington's disease

UCLA research identifies a potential strategy that may lead to treatment for the disorder. A new study examining the role that star-shaped brain cells called astrocytes play in Huntington’s disease has identified a potential strategy that may halt the disease and repair some of the damage it causes. Astrocytes interact […]

Deaf infants more attuned to parent’s visual cues, study shows

Eye gaze helps infants communicate. Through everyday interactions, eye gaze establishes a social connection between parent and child and is linked to early word learning. But can learn experiences before a baby’s first birthday prompt babies to pay more attention to their parent’s eye gaze? To test this, a research […]

New drug shows promise as immune therapy for cancer

A therapy developed by Yale researchers stimulates immune cells to shrink or kill tumors in mice, according to a new study published in the Journal of Experimental Medicine. The therapy is effective alone or in combination with existing cancer immunotherapies, and it appears to have lasting effects, the researchers said. The […]

Yale scientists help immune system find hidden cancer cells

Cancer cells are masters at avoiding detection, but a new system developed by Yale scientists can make them stand out from the crowd and help the immune system spot and eliminate tumors that other forms of immunotherapies might miss, the researchers report in the journal Nature Immunology. The new system […]
