North Korea wants the world to know it has a working thermonuclear bomb

September 7, 2017 - 14:26 -- Admin

Over the weekend, North Korea unveiled a new weapon. It is small, maybe small enough to fit in the nose cone of a missile. It is powerful, detonating with the force of possibly 140 kilotons, or almost 10 times the destructive power as “Little Boy,” the bomb dropped on Hiroshima in 1945. This thermonuclear warhead is shiny, bare metal like the naked skins of the early jets that first fought in the skies above Korea almost 67 years ago.

Space weather may be killing sperm whales

September 7, 2017 - 14:26 -- Admin

The same phenomenon that creates the Northern Lights might also be confusing male sperm whales. In case you've forgotten already (really, how could you?), early 2016 brought a veritable tidal wave of beached spermaceti in the North Sea. No one could figure out why at the time, but thanks to a study in the International Journal of Astrobiology, we now have a working hypothesis: it was those gosh darned solar storms at it again.

China's looking to one-up Elon Musk's hyperloop

September 7, 2017 - 14:26 -- Admin

Hyperloops, the developing mode of transit that promises to zip people frictionlessly in pods and tubes, have long been associated with the innovations and dreams of billionaire Elon Musk. More recently, however, it's captivated the imaginations of others, including, now, a Chinese aerospace giant. The China Aerospace Science and Industrial Corporation (CASIC), a well-heeled newcomer to the mass transit industry, is betting big on its supersonic T Flight 'flying train.'

Look at the mysterious 'dragon booger' found in Vancouver's Lost Lagoon

September 4, 2017 - 12:12 -- Admin

“Dragon boogers” go by many names. “Moss animals,” for one, and “bryozoans,” for another. They're also known as “ectoprocta,” meaning “anus outside.” If you're unfamiliar with the phylogeny of aquatic invertebrates, it might seem unnecessary to distinguish creatures with anuses outside from creatures with anuses inside. And yet, it is necessary—which is the beauty of water-dwelling blobs.

Strange signals were just spotted coming from a distant galaxy

September 1, 2017 - 13:17 -- Admin

Long ago, 15 bright radio pulses emerged from a dwarf galaxy about 3 billion light years away from Earth. Last Saturday, a telescope in a remote area of West Virginia picked up those signals from a distant corner of the universe, and yesterday, a group of astronomers and astrophysicists shared preliminary results on their observations.

What happens when you heat the Antarctic ocean by a single degree?

September 1, 2017 - 13:17 -- Admin

What happens to aquatic life along the Antarctic seabed when the surrounding waters warm by a degree or two? Researchers spent six years developing a heating device capable of heating the ocean—while surviving the region's cutting climate—in an attempt to find out. Their findings were released today in the journal Current Biology, and suggest that even this tiny shift could have a big impact on the local ecosystem.

Scientists still want to turn our gut bacteria into medicine

September 1, 2017 - 13:17 -- Admin

The bacteria inside our guts—which collectively make up the so-called gut microbiome—are incredibly diverse, with countless species and strains. But they also differ depending on the individual, with one person's microbiome having little to do with another's. And scientists have found that these differences can relate to our health. A person with diabetes is more likely to have a certain suite of microbes than a person without diabetes, for example.

North Korea's missile test over Japan was a threatening proof of concept

September 1, 2017 - 13:17 -- Admin

At about 6am on local time Tuesday morning, Japan's government issued a warning to its citizens that a missile was headed their way. That missile, fired from North Korea, crashed into the Pacific Ocean 575 miles east of Japan just 14 minutes after launch. This test was the third time that North Korea's ever successfully launched an object over Japan, and the first time that the object in question was explicitly a missile.
