Why Hawaii is trying to ban a common sunscreen

May 1, 2017 - 09:49 -- Admin

The waters surrounding Hawaii's eight main islands contain more than 410,000 acres of living coral reefs. If strung together, the reefs would be bigger than Oahu, Hawaii's third largest island. And because of Hawaii's geographic isolation, the reefs support unique life. The Hawaiian Monk Seal, the Bandit Angelfish—even some of the types of coral that comprise the reef itself—are found nowhere else on earth. It's a shame that our sunscreen might be killing them.

Antarctica's Blood Falls: not so mysterious, but still freaky as heck

May 1, 2017 - 09:49 -- Admin

You may have seen headlines proclaiming that the great mystery of Antarctica's "Blood Falls" has finally been solved. That's a little silly, because the big mystery—the question of why blood-like bright red liquid oozes out of the otherwise white surface of Taylor Glacier—hasn't been all that mysterious for some time.

Why NASA is running out of spacesuits

May 1, 2017 - 09:49 -- Admin

Today's spacesuits are designed to work well while astronauts float around outside the International Space Station. But they're not quite right for walking around on the moon or Mars—they're too heavy and don't provide enough flexibility in the hips and knees. That's why NASA is investing in a next-generation spacesuit for exploring deep space.

China's naval task force begins its 6-month, 20-nation grand tour

China will be sending a multi-warship task force across the oceans for six months, setting a record for the longest Chinese naval deployment. While the PLAN has not engaged in combat for nearly 30 years since the 1988 South China Sea skirmishes with Vietnam, it has made it a priority to display its naval might and participate in exercises to build relationships with other navies.

It's official: NASA's new heavy lift rocket won't launch until 2019

May 1, 2017 - 09:49 -- Admin

This may not come as a total surprise, but NASA has announced it's delaying the maiden flight of its super-duper powerful rocket. The Space Launch System (SLS)—destined to carry humankind beyond Earth's orbit, to the moon and Mars—was supposed to launch in late 2018. Now the target has changed to sometime in 2019.

These hot robots will help us find life on icy moons

May 1, 2017 - 09:49 -- Admin

The moons orbiting Jupiter and Saturn lie far from the sun's warmth. Most have no atmosphere, and many are covered in an icy sheath miles thick. They're also our best bet for finding life in our own solar system. Beneath the frozen crusts lie vast oceans, and space agencies in the United States and beyond are hard at work on the robots that will one day visit them.

The US Navy is designing safer batteries, because no one wants a fire at sea

May 1, 2017 - 09:49 -- Admin

Our smartphones and other gadgets are powered by lithium-ion batteries, but as companies like Samsung know all too well, those charge-holders can be flammable under the wrong conditions. The hazards of lithium-ion batteries are also a concern for another group, one with a strong incentive to keep fires at bay: the U.S. Navy. Now chemists at the U.S.
