Harnessing the sun’s energy with orbital space power stations and beaming the power to Earth has been a science fiction dream ever since Isaac Asimov wrote a 1941 short story called “Reason.” But the idea has never quite gotten off the ground despite decades of intermittent interest and research for the United States and other countries ...read more

The dream of a human habitat in orbit about the moon came a step closer on Sept. 27, when NASA and the Russian space agency (Roscosmos) signed up to a common vision for future human exploration. The project, a follow-up to the International Space Station (ISS), involves a facility placed in orbit somewhere between the Earth and the moon – a region known as cis-lunar space. Seen as a stepping-stone on the wa ...read more

As it turns out, chimpanzees don’t need to see in order to do, no matter what the old mantra might lead you to believe.
A common belief among researchers is that chimps need to watch other members of their communities use tools before they can pick the behavior up. In a study published in PeerJ in September, researchers from the University of Birmingham, and the University of Tübingen challenged this belief and checked to see if it would h ...read more
Eating is one of the great pleasures of life. But eating too much places people at risk for chronic illnesses and shortens life expectancy. Seven of 10 Americans are overweight or obese, according to the Centers for Disease Control and Prevention. Being overweight is so common, people don’t recognize when they’ve crossed the belt line; only 36 percent of overweight/obese people think they weigh too much, says a recent Gallup poll.
People want to feel healthy ...read more
You should never bring a knife to gunfight, or try to beat a bird with ant repellant. That’s how the expression would go if a wood tiger moth coined it, anyway. Other animals are lucky if they have the resources to make just one poison. But this moth is the first species known to make two different chemical weapons that target different predators.
The moth, Arctia plantaginis, lives throughout the Northern Hemisphere. Its wings are bright and boldly patterned, a tactic tha ...read more
