What Happened
This week, scientists made several groundbreaking discoveries that shed new light on the natural world and the latest advancements in technology. From the surprising ways stress affects bees to the latest discoveries in rare earth elements and ancient fossils, here's a rundown of the latest science and tech news.
Stress Gives Bees Sharper Vision and Faster Reactions
Researchers at Newcastle University discovered that stress gives bees sharper vision and faster reactions. The study, published in the Journal of Experimental Biology, found that short-term stress affects early visual perception and decision-making in bees. Dr. Vivek Nityananda, senior lecturer at Newcastle University, said, "While stress is negative, it can prepare an individual for future challenges by changing how they respond."
Can North America Mine Enough Rare Earth Elements?
A University of Michigan study published in Resources, Conservation and Recycling found that North America has enough deposits of rare earth elements to begin looking in its own backyard for these critical components of modern technology. Rare earth elements are necessary for the production of many products, including cellphones, car batteries, and renewable energy technologies.
42-Year Study Tracks 'Forever Chemicals' in the Great Lakes
University of Notre Dame researchers analyzed 42 years of biological records from the Great Lakes, unveiling how per- and polyfluoroalkyl substances (PFAS), or "forever chemicals," have moved across the region, contaminating a variety of wildlife. The research, published in the Journal of Environmental Quality, found that PFAS have been present in the Great Lakes for decades, with levels increasing over time.
Fossilized Babies of Ancient Crocodile-Like Predators Uproot Understanding of Animal Adaptation
New fossil evidence suggests that ancient crocodile-like predators did not undergo a metamorphosis the way that modern amphibians do when growing up, challenging a long-standing scientific belief that amphibians, reptiles, and mammals evolved from animals that had a tadpole stage. The discovery, published in a scientific journal, sheds new light on the evolution of life on land.
Before SpaceX IPO, Investors in China Secretly Acquired Stakes
A private investor list obtained by ProPublica revealed that investors in China secretly acquired stakes in SpaceX before its initial public offering. The list sheds light on the delicate issue of foreign investment in US military contractors, which is heavily regulated.
Key Facts
- What: Breakthroughs in bee vision, rare earth elements, ancient fossils, and foreign investment in SpaceX
- When: This week
- Impact: Advances in science and technology, implications for foreign investment in US military contractors
