A genetic mutation possibly linked to malarial resistance may have helped drive the evolution of the genus Homo, humans’ ancient ancestor, a new study finds.
NASA’s long-lived Mars rover Opportunity that beat newcomer sister probe Curiosity to an area containing water-formed clay minerals, has found that the spot may be far richer than scientists first realized. A new study looks at chemicals spotted by a Mars-orbiting spacecraft to conclude that Endeavour Crater, which Opportunity reached in August 2011 after a…
CodeHeart, a mobile application to speed diagnosis of heart attacks, has been under development in the Washington DC area for two years, but it’s still struggling to enlist emergency medical crews’ participation for a pilot project. The slow going reflects the complicated nature of mobile solutions for the health-care-provider market, which has generally taken a…
Created in 1947, the doomsday clock graphically reflects how close humanity might be to human-induced apocalypse, in terms of the “number of minutes to midnight”—at which time, presumably, time itself will no longer matter. Currently, the clock is set at five minutes to midnight. Nuclear weapons continue to be the most urgent global threat to…
After decades of wandering in the scientific wilderness, cold fusion may be returning to the land of the acceptable. It’s been more than 20 years since esteemed researchers Stanley Pons and Martin Fleischmann electrified the world with news that they’d observed low-energy nuclear reactions at the atomic level that generated excess heat, holding out the…
Whether we are searching the cosmos or probing the subatomic realm, our most successful theories lead to the inescapable conclusion that our universe is just a speck in a vast sea of universes. Author Metanexus Editors
How much warning will we really have if a Near Earth Asteroid (NEO) is about to hit Earth? The answer is pretty grim. “With so many of even the larger NEOs remaining undiscovered, the most likely warning today would be zero,” NASA informs us. We would see nothing at all until suddenly, just as the…
