Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. And after months of rebuilding following an explosive initial launch in April, SpaceX made a second attempt at launching its deep-space rocket system Starship, but not all went according to plan. Defying gravitySpaceX's megarocket Starship launched for a second test flight from Starbase in Boca Chica, Texas on Saturday. The Wonder Theory team is taking some time off for Thanksgiving.

☆ How head lice reveal secrets about human origins
  + stars: | 2023-11-13 | by ( Manav Tanneeru | Katie Hunt | ) edition.cnn.com   time to read: +5 min
CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

☆ How lice evolved alongside humans to become the perfect pests — and trackers of human migration
  + stars: | 2023-11-10 | by ( Sebastian Cahill | ) www.businessinsider.com   time to read: +3 min
Head lice have plagued communities for centuries across the world. Now, a new study suggests lice DNA can help track human migration from continent to continent. AdvertisementAdvertisementTo complete the study, the researchers looked at 175 head lice from 18 sampling locations and nine geographic regions. More recently, around the 16th century, European colonizers brought their own head lice to the Americas when they arrived, according to NPR.
