Since 2012
Researchers have uncovered surprising evidence that anxiety may be controlled not by neurons but by two dueling groups of immune cells inside the brain. These microglia act like biological pedals—one pushing anxiety forward and the other holding it back.

New observations show that asteroid 1998 KY26 is a mere 11 meters across and spinning twice as fast as previously thought. The discovery adds complexity to Hayabusa2’s 2031 mission but also heightens scientific interest. The asteroid’s composition remains uncertain, making the encounter even more compelling. Insights from this work could improve future asteroid-defense and exploration efforts. Source link
An 18th-century mechanical artwork depicting Mount Vesuvius’ eruption has finally erupted — 250 years later. University of Melbourne students reconstructed Sir William Hamilton’s imaginative fusion of art and engineering using modern technology. Their re-creation glows with programmable lights and movement, reanimating history’s forgotten passion for science and spectacle. Source link
Researchers found that life expectancy growth in wealthy nations has dramatically slowed since 1939. Once driven by major reductions in child mortality, longevity gains are now limited by slower progress in older-age survival. The study suggests no generation since 1939 will live to 100 on average, reshaping how societies must plan for aging and pensions. Source link
