☆ A Fish That Fishes for Other Fish Lives Its Life Upside Down
  + stars: | 2023-11-22 | by ( Elizabeth Anne Brown | ) www.nytimes.com   time to read: 1 min
Usually, a belly-up fish isn’t long for this world. But video evidence from the deep ocean suggests that some species of anglerfish — the nightmarish deep-sea fish with bioluminescent lures — live their whole lives upside down. “Just when you think they couldn’t get any weirder, anglerfish outdo themselves,” said Pamela Hart, an associate professor at the University of Alabama who researches fish that live in extreme conditions. The behavior, documented earlier this month in the Journal of Fish Biology, is “beyond anyone’s wildest imagination,” said Elizabeth Miller, who studied the evolution of deep-sea fish as a postdoctoral fellow at the University of Oklahoma. (Neither Dr. Miller nor Dr. Hart was involved in the discovery.)

☆ Florida Turtle Nests Are Doing Great. When They Hatch, Expect Mostly Girls.

Green sea turtles had an exceptional nesting season on Florida’s beaches in 2023, with volunteers counting more than 74,300 nests, according to preliminary data. That beats the previous record, from 2017, by a staggering 40 percent. “The increase is an explosion” and a welcome surprise, said Simona Ceriani, a research scientist who coordinated the annual survey for the Florida Fish and Wildlife Conservation Commission, the state agency that regulates and manages wildlife. Sea turtles don’t reach sexual maturity until their twenties or thirties, so what Florida is seeing now is very likely the result of conservation measures put in place after green sea turtles were listed under the Endangered Species Act in 1978, Dr. Ceriani said. Those impressive nesting numbers are just “half the story,” according to Jeanette Wyneken, a professor at Florida Atlantic University who has studied nesting sea turtles for more than three decades.

☆ Your DNA Can Now Be Pulled From Thin Air. Privacy Experts Are Worried.

That could pose dilemmas for the preservation of privacy and civil liberties, especially as technological advancement allows more information to be gathered from ever smaller eDNA samples. The results of their research, published Monday in the journal Nature Ecology & Evolution, demonstrate that scientists can recover medical and ancestry information from minute fragments of human DNA lingering in the environment. Forensic ethicists and legal scholars say the Florida team’s findings increase the urgency for comprehensive genetic privacy regulations. Genetic trash to genetic treasureIt has been clear for decades that fragments of our DNA cover the planet like litter. Wildlife researchers embraced environmental DNA anyway because they’re only looking for very small segments of DNA — scanning for what they call bar codes that will identify the creatures in a sample to a species level.
