The range of effects caused by rhinoviruses – the pathogens responsible for the common cold – motivated scientists at Yale University to study the human nasal epithelium and uncover a previously undescribed defense mechanism. The interferon-mediated protective response in these cells can limit infection, whereas a maladaptive response tends to worsen it. Based on these findings, the researchers have identified potential therapeutic targets to reduce inflammation associated with rhinovirus infection.

A new systematic review and meta-analysis of studies looking at a possible association between Tylenol (acetaminophen) use in pregnancy and neurodevelopmental disorders in children concludes there is no evidence of any meaningful risk. The study was carried out by researchers in the U.K., Italy, Sweden and Norway, in response to U.S. Secretary of Health and Human Services Robert Kennedy saying last September that there is a link. Unless medically necessary, it is “irresponsible” to take Tylenol during pregnancy, Kennedy said.
