Scientists have found a previously unrecognized variant of HIV that’s more virulent than usual and has quietly circulated in the Netherlands for the past few decades. Thursday’s report isn’t cause for alarm: HIV medicines worked just as well in people with the mutated virus as everyone else and its spread has been declining since about 2010. It was discovered as part of efforts to better understand how HIV continues to evolve. (Neergaard, 2/3)

Healthy mouth, healthy baby? For years, scientists have been exploring the link between poor oral health and giving birth too early. Now, new research presented Thursday raises the possibility that something very simple and inexpensive might make a difference: chewing sugarless gum.

An estimated 18,000 Americans — nearly half of whom were children — went to emergency rooms across the U.S. in 2020 for injuries sustained when furniture, a TV or another appliance tipped over and hurt them. A report released Thursday by the Consumer Product Safety Commission also found that there have been 581 tip-over fatalities in the U.S. since 2000. Four in five of the deaths were kids. Although the data shows an overall decline in "product instability" injuries and deaths recently, each year thousands of people are still treated for injuries and some die from what authorities say are preventable accidents.

Dallas-based Southwest Airlines will bring back onboard alcohol sales to most flights and an expanded beverage offering starting Feb. 16, the carrier announced Thursday.
