This week in science brought fascinating discoveries and observations, from blue dogs in Chernobyl to innovative mushroom-based technology. Here’s a summary of the key highlights.
Bright Blue Dogs in Chernobyl
Reports have emerged of bright blue dogs seen in the Chernobyl Exclusion Zone. Researchers suspect the unusual color results from exposure to chemical dyes rather than radiation. The Clean Futures Fund stated they are working to capture these dogs for further study to understand the phenomenon.
The Benefits of Going Gray
New research from Japan suggests that gray hair might actually serve a protective role against cancer. A study led by Emi Nishimura at the University of Tokyo found that gray hair results from the body’s mechanism to eliminate damaged cells. This discovery links hair graying with stem cell responses and may change how we view these two processes.
Revolutionizing Computer Memory with Mushrooms
Scientists have created a new type of computer memory using shiitake mushrooms, achieving a performance that rivals traditional silicon-based chips. This ‘mushristor’ operates at a frequency of 5,850 Hertz and boasts an impressive accuracy of 90%. This development marks a significant step towards using biological materials in technology.
Longer Walks for Better Heart Health
A recent UK study indicates that longer walks may benefit heart health more than aggregating multiple shorter walks. Matthew Ahmadi, a public health researcher at the University of Sydney, emphasizes the importance of taking one or two longer walks each day, focusing on pacing rather than simply counting steps.
Creative Activities Keep Your Brain Young
Engaging in creative activities such as art, music, and dancing can significantly reduce biological brain age. Research indicates that tango dancers have brains roughly seven years younger than their chronological age, while musicians and visual artists show similar benefits. Gamers, too, exhibit a brain age that is around four years younger.
New Antibiotics: A Promising Discovery
A powerful antibiotic was discovered in the common bacterium Streptomyces coelicolor. Notably, Enterococcus bacteria exposed to this compound for 28 days did not develop resistance, highlighting its potential for long-term effectiveness in treating infections.
These remarkable findings showcase the exciting advancements in science and technology that could impact health and our understanding of the natural world.
