Seeds are surreptitiously hitching a ride on human visitors to Antarctica, threatening to sow invasive species in one of the last remaining pristine environments on Earth. About 20 percent of visitors to the frozen continent bring stowaway seeds on their clothing and luggage, according to a new study. The research highlights the potential risk to Antarctica’s indigenous species, but also the impressive traveling abilities of plants.
The Russian scientists drilling into ancient buried Antarctic Lake Vostok have reached their destination, the Russian news agency Ria Novosti reported today. The team is apparently alive and well despite a week of suspicious radio silence, but more details are to come about what they’ve found buried under two miles of ice.
At Lake Vostok, the coldest place on earth, a Russian team of scientists have been attempting to drill through a two-mile-thick ice layer into the subterranean lake, which has been isolated for some 20 million years. But the team has not been heard from for five days, according to a report by the Global Post.

This month, Russian scientists will nearly reach the waters of Lake Vostok, which have been sealed more than two miles under Antarctica’s surface for at least 15 million years. If all goes well, the drill will never touch the fragile ecosystem.
A prolonged chill in the atmosphere high above the Arctic last winter led to a mobile, morphing hole in the ozone layer, scientists report in a new paper. It’s just like the South Pole hole we all studied in school, but potentially more harmful to humans — more of us live at northern latitudes. Here are five things you need to know about it.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
