    Life under ice

    Even by Antarctic standards, the Lake Vostok research station is inhospitable. The outpost at the heart of the frozen continent holds the record for the lowest naturally occurring temperature ever observed on Earth. Scientists commonly describe the place as punishing, unforgiving, the most desolate place on the planet.

    That’s nothing. Nearly 4,000...

    Laser proposed to deflect space junk

    It won’t prevent Armageddon, but a simple ground-based laser system could nudge small pieces of space junk away from satellites to prevent collisions, a new study suggests.

    The proposed system uses photons generated by a medium-power laser and aimed into space through a 1.5-meter telescope. The photons exert pressure on space debris in low-Earth orbit, gently pushing the...

    Climate not really what doomed large North American mammals

    Evidently, my dear Watson, the climate didn’t do it. Scientists weighing in on a cold case open since the end of the most recent ice age — the massive die-offs of North America’s largest mammals — arrived at that conclusion courtesy of some very tiny clues. The spores of a fungus that thrived in and on those creatures’ dung suggest changes in habitat didn’t cause the extinctions. As a result...

    Networks reveal concentrated ownership of corporations

    Researchers have made the first maps of corporate stock ownership for the stock markets of a large number of countries, 48 in all. The new network analysis technique reveals “backbones” in these ownership networks: big players that together own a controlling stake in more than 80 percent of the companies in the markets.

    In these network diagrams, nodes represent either a company with...

    Seafloor Chemistry: Life's building blocks made inorganically

    Hydrocarbons in the fluids spewing from a set of hydrothermal vents on the seafloor of the central Atlantic were produced by inorganic chemical reactions within the ocean crust, scientists suggest. The finding holds possibly profound implications for the origins of life.

    The Lost City hydrothermal field, which sits on the side of an undersea mountain about 2,500...
