Blood Falls: Flowing Network Discovered Below Antarctica’s Dry Valleys

Research shows there may be an entire world underneath Antarctica’s ice-free Dry Valleys, which on the surface may seem hostile to life. Below the surface lies rivers of liquid salt water which flow into subsurface lakes, every drop of which could be swarming with microbial life. One of Antarctica’s most unique features, the briny, rusty-red colored Blood Falls, could possibly […]

That’s usually a problem for architects and engineers, who have to […]

When the Red Planet was partly blue

Astronomers have found the strongest evidence yet that ancient Mars had a massive ocean for millions of years— an indication that the Red Planet once had everything necessary to support life. Shortly after Mars formed 4.5 billion years ago, NASA scientists say, the planet was wet, with enough water to cover the entire planet to a depth of about 450 […]

How elephants defy getting cancer

How elephants defy getting cancer

As the world’s largest land mammals, elephants should suffer one of the highest cancer rates—they simply have far more cells that could potentially mutate and become malignant. But new research reveals that elephants rarely get cancer—and the reason why may help in the search for human treatments. Only about 4.8 percent of elephants die from cancer, compared with up to […]
