In this week’s science headlines: Researchers uncover a potent new antibiotic, creative hobbies prove surprisingly beneficial for brain health, canine oddities in Chernobyl, and intriguing insights into gray hair.
New Antibiotic Discovery Offers Hope Against Resistant Bacteria: Scientists have identified a promising antibiotic compound derived from the common bacterium Streptomyces coelicolor. Initial tests show the antibiotic effectively combats Enterococcus bacteria, and crucially, the bacteria didn’t develop resistance even after prolonged exposure. This suggests the antibiotic could maintain its efficacy over extended periods.
Unleash Your Inner Artist (and Gamer!) for a Younger Brain: Engaging in creative activities like art, dance, music, and even gaming can significantly reduce your “brain age,” according to new research. Tango dancers exhibited brains that appeared over seven years younger than their actual age, while musicians, visual artists, and gamers showed brain ages five to six years, and four years younger respectively.
Blue Dogs Spotted in Chernobyl Zone, Cause Remains a Mystery: Bizarre bright blue dogs have been observed roaming the Chernobyl Exclusion Zone. While radiation is not the suspected cause, researchers believe the coloration likely stems from the dogs coming into contact with chemical dyes. Efforts are underway to capture the animals and determine the source of the dyes.
Gray Hair Linked to Cancer Prevention? Researchers in Japan propose that gray hair might be a side effect of the body protecting itself from cancer by eliminating risky, damaged cells. The study suggests that the stem cells responsible for hair color can be diverted to either depletion or proliferation depending on stress and microenvironmental signals, reframing graying and melanoma as related responses to stem cell stress.
Mushroom-Based Computer Memory Shows Promise: In an innovative approach, researchers have developed a type of computer memory using shiitake mushrooms. Dubbed a “mushristor,” the device achieved a switching speed of 5,850 Hertz with 90 percent accuracy, showcasing performance comparable to traditional silicon-based chips.
Longer Walks Trump Shorter Ones for Heart Health: A new UK study indicates that longer walks offer greater benefits for cardiovascular health than multiple shorter walks, even when the total number of steps is the same. Researchers emphasize that achieving 10,000 steps daily isn’t the only pathway to improved heart health. Incorporating one or two longer walks of at least 10-15 minutes each could have significant advantages, particularly for those who are less active.
