## Resource

Scientists have uncovered evidence that lateralized behavior — the same phenomenon behind human handedness — dates back over 550 million years to a tiny seafloor creature called Spriggina floundersi, pushing the origins of this trait deep into the Ediacaran period. Ancient DNA analysis is also rewriting the timeline of dog domestication, revealing that canine physical diversity began far earlier than thought, shaped by thousands of years of co-evolution alongside migrating humans. On the materials science front, a newly engineered cobalt aluminum nanolaminate alloy shatters the long-held strength-versus-brittleness tradeoff, clocking in at up to ten times stronger than structural steel with massive implications for aerospace engineering. Meanwhile, MIT engineers have built an insect-scale flying robot capable of navigating disaster debris fields, and Antarctic scientists have captured the first direct evidence of surface meltwater lubricating the base of glaciers — accelerating their slide toward the ocean.
