While the connection between air pollution and lung disease could appear obvious, the link between breathing in toxins and suffering memory loss looks about as clear as a cloud of cigarette smoke.Scientists at Scripps Research Institute first identified how contaminants in smog, pesticides, and other airborne chemical can affect the brain. Now they have identified a way to potentially reverse those effects, they report in the Proceedings of the National Academy of Sciences.Learning About Memory ...read more
Polar bear cubs are incredibly cute — and amazingly elusive. Their mothers dig dens under the snow in remote areas. Protecting cubs is key to the species’ survival. Under half of all polar bear cubs make it to adulthood.To help understand the act of denning — essential to the species survival — a team of scientists for the first time combined satellite tracking collars on mother bears with remote cameras aimed at the bears’ snow lairs. They observed bears near Svalbard, a Norwegian arc ...read more
In 2025, Dry January got a boost from the Surgeon General: an advisory about alcohol’s role in cancer and a warning about the risks of drinking. “Alcohol consumption,” the report stated, “is the third leading preventable cause of cancer in the United States, after tobacco and obesity,” increasing the risk of cancer in at least seven sites: mouth, throat, larynx, esophagus, breast, liver, and colon.With the advisory drawing our attention to the issue, it’s a good time to take a look ...read more
Giant panda bears evolved away from other bear species about 20 million years ago. Though they have similar characteristics, like body shape and digestive system, they greatly differ in preferred diets. Most bear species will happily feast on meat, fish, and berries, while pandas tend to stick to bamboo. A new study published in Frontiers in Veterinary Science points out that pandas have evolved in specific ways to make eating bamboo easier, including a pseudo thumb for holding bamboo and flatt ...read more
One would think that astronauts’ living quarters in space need to be perfectly sterilized, but it turns out that creating a "dirtier" environment with more microbes from Earth may boost their health. New research has shown that the International Space Station (ISS) is overly sterile, and while this may not sound like an issue, it carries some surprising consequences; the sterile nature of the station has led to a low diversity of microbes, which could be what is causing astronauts to develop h ...read more
