Fastest-Rotating Rock Known, Larger Than 6 Football Fields, Is Rubin Observatory’s First Discovery In A Nutshell Record breaker: Asteroid MN45 spins once every 1.88 minutes (about 765 times per day) making it the fastest-rotating large asteroid known to science Defying physics: Scientists found 19 asteroids spinning faster than the theoretical “spin barrier” of 2.2 hours, with three completing rotations in under 5 minutes Surprisingly strong: These ultrafast rotators must be [...]

Research led by Dr. Mayana Zatz and Dr. Mateus Vidigal de Castro (University of São Paulo) In A Nutshell Three Brazilian supercentenarians survived COVID-19 in 2020 before vaccines existed, showing remarkably strong antibody responses that suggest exceptional immune resilience even at ages 110+ Brazil hosts three of the world’s 10 oldest living men, and its genetically diverse population harbors over 8 million undescribed genomic variants, including rare protective genes invisible [...]

In A Nutshell Archaeologists discovered stone tools at three sites in Kenya spanning 300,000 years (2.75 to 2.44 million years ago), showing early humans maintained the same effective technology across geological timescales Toolmakers were surprisingly selective, consistently choosing fine-grained chalcedony over more abundant basalt because it produced sharper, more predictable edges The tools appeared during a dramatic environmental shift when East Africa dried out, with rainfall [...]

Artist's illustration of Venus. (© Igor_Filonenko - stock.adobe.com) Astronomers warn that Venus's orbital neighborhood may hide large space rocks that slip past Earth's telescopes. In A Nutshell Some asteroids orbit near Venus in paths that keep them hidden from Earth's telescopes. Simulations show these objects could pack city-destroying impact power. Only 20 Venus co-orbital asteroids are known, but many more likely exist. Space-based telescopes near Venus [...]

Vulcanidris cratensis fossil (Credit: Lepeco et al / Current Biology) In a nutshell Scientists discovered the oldest known ant fossil (113 million years old) in Brazil, pushing back the confirmed timeline of ant evolution by 13 million years. The fossil belongs to extinct “hell ants” with unusual upward-pointing jaws, suggesting they had specialized hunting techniques different from modern ants. The discovery reveals hell ants lived in diverse environments across multiple [...]

SÃO PAULO, Brazil — Anyone who’s experienced the disappointment of finding moldy strawberries in their refrigerator just days after purchase will appreciate this innovation. New research from Brazil could revolutionize how we store and enjoy one of America’s favorite fruits with a natural coating that keeps strawberries fresh for up to eight days longer than normal. According to a study published in Food Chemistry, this novel coating minimizes weight loss [...]

In a nutshell Using resistance-based weight machines twice a week helped older adults with mild cognitive impairment maintain memory performance, while a non-exercising group showed no improvement. Brain scans revealed that resistance training preserved the volume of memory-related regions, the right hippocampus and precuneus, that typically shrink with age and dementia risk. The study also found that resistance training improved the brain’s white matter integrity, suggesting it [...]

In a nutshell Human language capacity existed at least 135,000 years ago, much earlier than previously thought, according to genomic evidence from population divergence studies. The 35,000-year gap between language capacity (135,000 years ago) and widespread symbolic behaviors (100,000 years ago) suggests language gradually transformed how humans thought and interacted with their world. All modern human populations share language capabilities with similar structures, indicating that [...]

Current 10-second balance tests may miss early warning signs of fall risk in older adults; researchers recommend extending tests to 23 seconds or longer for better prediction For every extra second someone can maintain challenging positions like heel-to-toe or single-leg stance, their risk of falling in the next 6 months drops by 5% Healthcare providers can use this simple timing test without special equipment, making it accessible for any clinical setting while potentially preventing [...]
