Researchers are bridging mouse and human data to reveal the biology of senescent cells. Senescent cells stop dividing in response to stressors and seemingly have a role to play in human health and the aging process. Recent research with mice suggests that clearing senescent cells delays the onset of age-related dysfunction and disease as well as all-cause mortality.

The biomarker, called 'brain-derived tau,' or BD-tau, outperforms current blood diagnostic tests used to detect Alzheimer's-related neurodegeneration clinically. It is specific to Alzheimer's disease and correlates well with Alzheimer's neurodegeneration biomarkers in the cerebrospinal fluid. Scientists hope that monitoring blood levels of BD-tau could facilitate screening and enrollment of patients from populations that historically haven't been included in research cohorts.

Spontaneous, random baby movements aid development of their sensorimotor system, according to new research. Detailed motion capture of newborns and infants was combined with a musculoskeletal computer model, to enable researchers to analyze communication among muscles and sensation across the whole body. Researchers found patterns of muscle interaction developing based on the babies' random exploratory behavior, that would later enable them to perform sequential movements as infants. Better understanding how our sensorimotor system develops could help us gain insight into the origin of human movement as well as earlier diagnosis of developmental disorders.
