A new antiviral defense system discovered by Columbia scientists offers clues to telomerase’s origins and could inspire new approaches to studying aging and improving cell therapies.

Infants born to mothers who ate a healthy, Mediterranean-style diet during pregnancy were at lower risk for colic and eczema, according to a new study by researchers at Harvard T.H. Chan School of Public Health, Boston Children’s Hospital, and Harvard Pilgrim Health Care Institute. The researchers also found that regularly consuming seafood during pregnancy helped lower an infant’s risk for these conditions.

Hospitals and policymakers routinely face a difficult question when investing in specialized emergency services: Will adding another facility improve care, or would those resources do more good somewhere else? New UC San Francisco research suggests the answer depends heavily on what people already have access to. In nearly 600,000 California heart attack patients, survival rates improved after specialized services opened in communities that previously lacked timely access. But where those services were already available, opening another facility increased the likelihood of receiving procedures only slightly and did not improve survival rates.

A recent study from Johns Hopkins Medicine reveals that both the liver and brain contribute pathways to differing symptoms of the same rare inherited disorder.
