Popular Science's Spaceship Design Contest Winners!This past April, we put out a call for your ambitious spaceship designs. The only real rules were that we wanted to see an image, and that "the ideas must meet a certain threshold of seriousness, ... More >
Pangea Broke Apart As Fast As Fingernails GrowHang on to your land masses: we now know that the continents split apart in a big hurry. University of Sydney researchers studying seismic data from hundreds of millions of years ago found that ... More >
The AI Bots Are About To Get EmotionalWe already interact with artificial intelligence in our daily lives. Furby and Clippy were early forms; driverless cars and Facebook's chatbots pick up the mantle today. But if AI is to continue ... More >
Roach Milk: The Next Superfood?Joining the ranks of pigeons and spiders, cockroaches are the latest animal of questionable merit to get milked in the name of science. More >
Graham Has IssuesThere's something a bit grasshopper-like about Graham. This man-sized sculpture sports a head that melds right into his torso, which is supported by a pair of strong, springy legs. But Graham's ... More >
Soldier are preparing for war with robots. Let me rephrase. Soldiers are preparing for war, alongside robots. As part of the Pacific Manned-Unmanned Initiative, soldiers with the U.S. Army's 25th Infantry Division tested prototypes of robots, to see if they might be useful in future battles.
When the Australian pygmy-possum goes dormant to save energy, it doesn't completely lose its ability to respond to danger. Pygmy-possums can smell smoke and begin to climb while in a state of torpor, scientists from the University of New England in Armidale, Australia reported today in the journal The Science of Nature. The results offer evidence that hibernating animals can wake up and flee an oncoming blaze.
Helmets may not be as old as war itself, but it's no coincidence that less than 25 years after the first recorded war, we have historical evidence of soldiers wearing helmets. Humans are nothing without their brains, and the protective bone of the skull isn't enough to withstand weapons made for, well, splattering bones. Humanity has at least 4,500 years of experience building helmets, and while weapons changed innumerable times in those millennia, helmet technology was always just a step behind.
We don't typically get rockets back in one piece. They're shot beyond the atmosphere at 18,000 miles per hour and come back moments or weeks later at hypersonic speeds, usually in bits and pieces left in the ocean. So if we're going to start bringing them back — as SpaceX sticks more and more landings — we'll need to know where to retire them, too.
