If the U.S. wants to keep its prominence as a world power and technological innovator in the 21st century, we need to work fast.
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…
Time, arguably our most precious nonrenewable resource, has a slippery nature in our minds. Sometimes it flows quickly. In other situations, it trickles at an unbearably slow pace. And, to the horror of many, it speeds as we age. Why should something as reliable as a ticking clock be perceived with such inconsistency? Claudia Hammond,…
A 5,500-year-old tomb possibly belonging to a Stone Age chieftain has been unearthed at a megalithic monument in the shape of a ship called the Ale’s Stenar (Ale’s Stones). The tomb, in Sweden, was likely robbed of stones to build the Viking-era ship monument. “We found traces — mostly imprints — of large boulders,” said…
A spacecraft orbiting Mars has detected carbon dioxide snow falling on the Red Planet, making Mars the only body in the solar system known to host this weird weather phenomenon. The snow on Mars fell from clouds around the planet’s south pole during the Martian winter spanning 2006 and 2007, with scientists discovering it only…
Astronomers have detected an alien planet that may be capable of supporting life as we know it — and it’s just a stone’s throw from Earth in the cosmic scheme of things. The newfound exoplanet, a so-called “super-Earth” called HD 40307g, is located inside its host star’s habitable zone, a just-right range of distances where…
In a special issue on human conflict, Science Magazine considers the deep evolutionary roots of violent confrontation – tracing the trajectory of violence and war throughout history, exploring racism, ethnic conflicts, the rise of terrorism, and the possible future of armed conflicts. The editors also consider our innate capacity to mediate conflict and our ability…
