I did not throw up. When I tell people that I've ridden in a zero-g plane, invariably they ask, propriety be damned, if I threw up. So, it's best to address that aspect of zero-g straight away. Though I dutifully stick the company issued barf bag in my flight suit's pocket—just in case—my stomach's contents remain my stomach's contents through the many 30-to-40 second cycles of less than Earth's gravity. Five other fliers—all men—are significantly less fortunate.
Snow can be soft and fluffy or stinging and icy; perfect for skiing or prone to melt. The difference lies in the shape of the flakes. They don't all look like the kind you see in emoji. Researchers have classified as many as 108 types, but according to Kenneth Libbrecht, a physicist at the California Institute of Technology, you can pare them down to four broad categories: plates, columns, needles, and dendrites.
As part of its celebration of the People's Liberation Army, the Military Museum of the Chinese People's Revolution in Beijing is showing off a range of exciting exhibitions, offering a peek into the PLA's new self-propelled artillery, cruise missiles, ballistic missile launchers, and—perhaps most notably—tactical unmanned aerial systems.
Millions of people are expected to turn their heads skyward to watch the Great American Eclipse on August 21. You might be one of them. But did you know that you can enjoy this natural wonder while also helping scientists out? Here are four ways that you too can be an eclipse scientist—at least for a day.
Every armory is a potential explosion waiting to happen. And in Eastern Ukraine, a stockpile of ammunition recently ignited, spewing smoke and fire into the sky in a dramatic video. The culprit? A small drone carrying a 1-pound grenade armed with the pyrotechnic substance thermite.
Every year on Easter in the Otago region of New Zealand, people gather to shoot thousands of bunnies. A police officer is on hand, not to arrest the hunters but rather to spur them on. This is the annual Easter bunny hunt, and by the time the day is done there will be literal piles of rabbit carcasses.
There are countless ways for a person to develop cancer, and this tangle of biological routes leading to illness can make it more difficult for researchers to develop treatments and cures. Scientists have already done a lot of work on sequencing the genes of cancer cells. That's given them insight into what a cancer cell looks like and how it grows endlessly. But to know what fuels those cells, and where they come from, scientists had to plot a course back to each cell's source.
Listen, Humpty Dumpty, I hate to break it to you, but while there are certain medical situations where a bandage is good enough to stick you back together again, this is not one of them. Sometimes, even the best intentions (and combined efforts of the reigning monarch's horses and men) aren't enough. Please, go consult with the slug mucus experts immediately.
