A newborn's genome can help detect the presence of bacterial infection in the bloodstream, according to a study in the journal Nature Communications.

A study in The New England Journal of Medicine found that women who have variants of the PALB2 gene have a 1 in 3 chance of having breast cancer through age 70. For those who also have a strong family history of breast cancer, the risk can rise to about 60%.
Women who went through menopause at a younger age had higher odds of developing type 2 diabetes compared with those who were older when menopause started, according to a study in Diabetes Care. The findings suggest that women who enter menopause before age 40 "may be a high-risk group to target for diabetes screening," said epidemiologist Elsa Strotmeyer, who was not involved in the study.
U.S. researchers assessed samples of babies' cries at age 6 months and found that the three babies with the highest-pitched cries were diagnosed with autism spectrum disorder at age 3. The cries of at-risk babies were described in the study as being rougher and having less clear quality than babies not considered at risk for autism. The study was published in the journal Autism Research.
