A new study from researchers at the University of Illinois at Urbana-Champaign linked acetaminophen with language delays in children. Susan Schantz, professor emerita of comparative biosciences and one of the authors of the study, spoke to CBS 2 about the findings. Schantz said the study looked at language development among children ages 2 and 3, and found that those whose mothers took acetaminophen, especially during the third trimester of their pregnancy, had smaller vocabularies and shorter sentence lengths.

For those with hearing loss, simply putting on hearing aids could be a lifesaver. New research, published Wednesday in The Lancet Healthy Longevity journal, showed that people with hearing loss who regularly wore hearing aids had a 24-percent lower mortality risk than those who never wore them, regardless of age, gender, socioeconomic status, race, type of insurance, severity of hearing loss and other medical conditions. And the worse someone’s hearing loss was, the greater was their risk of an earlier death. (Morris, 1/3)

But through the lens, Bianchi saw the unmistakable glimmer of Y chromosomes—dozens and dozens of them. “Clearly,” Bianchi told me, “part of her thyroid was entirely male.” The reason, Bianchi suspected, was pregnancy.

Researchers identified the enzyme responsible for urine's color, unraveling a mystery that's puzzled scientists for years, according to a study published Wednesday in the journal Nature Microbiology. "It's remarkable that an everyday biological phenomenon went unexplained for so long, and our team is excited to be able to explain it," Brantley Hall, an assistant professor in the University of Maryland's Department of Cell Biology and Molecular Genetics, said in a news statement. (Chasan, 1/3)
