UC Berkeley Study Links Sleep Deprivation to Junk Food Cravings

Study Links Sleep Deprivation to Junk Food Cravings

A UC Berkeley has linked sleep deprivation to junk food cravings, finding that high-level brain regions required for complex judgments and decisions become blunted by a lack of sleep, while more primal brain structures that control motivation and desire are amplified. Berkeley — A sleepless night makes us more likely to reach for doughnuts or […]

“Personalized” Tumor Vaccine Works on Hard-to-Treat Leukemia


New Vaccine Works on Hard to Treat Leukemia


In a newly published study, researchers observed a strong and selective immune response in some patients who received, shortly after the transplant, several doses of a “personalized” tumor vaccine composed of their own inactivated leukemia cells combined with an immune stimulant. Patients with advanced chronic lymphocytic leukemia (CLL) often receive donor transplants that effectively “reboot” […]
