☆ Tiny lizard ‘scuba dives’ and hides out from predators

Reptiles are astonishingly diverse, with extraordinary adaptations such as a tiny lizard in Costa Rica that has evolved a way to “scuba dive,” according to new research. Fantastic creaturesUsing the air bubble helps the anole to stay underwater longer, and the technique may help the tiny lizard hide from predators, researchers say. This ability allows the lizard to stay underwater for a prolonged period of time. Across the universeAn artist's concept depicts NASA's Voyager 1 spacecraft entering interstellar space, or the space between stars. Along the way, Voyager 1 found a thin ring around Jupiter and two new Jovian moons as well as five new moons orbiting Saturn.

☆ Diving lizard’s ‘scuba tank’ allows it to breathe underwater, scientists say

Footage that Swierk recently captured of submerged anoles shows prominent bubbles swelling and deflating on the reptiles’ heads. Diving anoles aren’t fast runners and rely mostly on camouflage to hide from predators such as birds, snakes, mammals and other lizards. For diving anoles, gular pumping may also play a part in circulating stored oxygen, affecting how long anoles can stay underwater. A throat-pumping action called gular pumping may play a part in circulating stored oxygen, affecting how long anoles can stay underwater. Another unresolved question is how diving anoles store and circulate oxygen while underwater.

☆ Sealed bottles of tattoo and permanent makeup ink test positive for millions of bacteria, FDA says

CNN —Sealed bottles of tattoo and permanent makeup ink, including some marked as sterile, contained millions of potentially dangerous bacteria, according to new research by the US Food and Drug Administration. Earlier studies have found high levels of bacterial contamination within sealed and sterile bottles of ink. Unfortunately, the study’s findings were not surprising, said John Swierk, an assistant professor of chemistry at Binghamton University, State University of New York, who has studied tattoo ink contamination. For example, using the same gloves to touch a client and the ink bottle is a hazard that can lead to tattoo ink contamination. “Tattoo inks are in the process of being regulated due to the Modernization of Cosmetics Regulation Act (of 2022) but much of that law dealing with tattoo inks has yet to be implemented,” Swierk said.
