The sun, at 4.6 billion years old, predates all the other bodies in our solar system. But it turns out that much of the water we swim in and drink here on Earth is even older. Up to half the water now on Earth was inherited from an abundant supply of interstellar ice as our sun formed. That means our solar system’s moisture wasn’t the result of local conditions in the proto-planetary disk, but rather a regular feature of planetary formation — raising hopes that life could indeed exist else ...read more

For years, Melanie Musson’s friends have marveled at her superpower: staying healthy no matter what germs are making the rounds. Colds and flu felled plenty of Musson’s dormmates in college, but the viruses always seemed to pass her by. “I never got sick once,” she says. “I got about five hours of sleep a night, I finished school in three years, and I worked 30 hours a week throughout. My best friends labeled me ‘the machine.’ ”Musson’s ironclad immune system also set her apa ...read more

Man has been domesticating animals for more than 15,000 years. Dogs are likely the first, followed by sheep, pigs, goats, and horses. The widely accepted criteria of “domesticated” include genetic differences from their ancestors, dependence on humans for food, and being unlikely or unable to breed with their wild counterparts. Although some people keep wild and exotic animals as pets, it’s not recommended. Here are six animals that people shouldn’t domesticate.1. Can Raccoons Be Domest ...read more

When the satellite communications failed on NASA’s Super Pressure Balloon-borne Imaging Telescope, SuperBIT, the team knew they were in danger of losing their astronomical imaging data, which the telescope had painstakingly gathered from above 99.5 per cent of the atmosphere. But the mission planners had a backup plan. Their idea was to drop the entire telescope, with all its data, to the ground by parachute so it could be used again. Having circumnavigated the southern hemisphere five times, ...read more

Animals and humans have coexisted since our early ancestors first emerged nearly 2 million years ago. Researchers have found artifacts from this time period, such as stone tools in the archaeological site Kanjera South in Kenya, showing the first tangible proof of ancient humans interacting with and hunting animals.This symbiotic relationship between humans and animals hardly comes as a surprise when domesticated pets like dogs and cats are commonplace in the modern world. However, the animals ...read more
