The Star that 'Nearly' Hit EarthAround 70,000 years ago, earth was a pretty bleak place. Homo erectus had just gone extinct, and we were all in mourning. But while we were distracted by things like the near-extinction ... More >

Thermal Solar Towers Are 'Vaporising' BirdsThe Crescent Dunes Solar Energy Project in Nevada is set to come online in March. Once completed, it will use thousands of mirrors to focus sunlight on a tower, melting millions of pounds of salt ... More >
Farmers Eye Drones For The FutureEven though humans have been farming for thousands of years, there's always a new trick to learn or a new technology to try. In modern times, these tricks often come attached to small flying ... More >
Acting as cheap flying cameras, drones already raise a lot of questions about privacy. But it's not just aerial photography people should worry about with drones. Earlier this month, AdNear, a Singaporean marketing company, flew drones with sensors that could detect cell phone signal strength and WiFi over part of Los Angeles. The drones identified and located people by the devices in their pockets, so that businesses could send highly-specific ads to their smartphones. The company praised this cyberpunk dystopian idea in a blog post, saying:
You can't trick us, Ceres. Out there in the asteroid belt, in the dark space between Mars and Jupiter, you've been keeping secrets. Scientists thought your shiny white spot was probably some kind of ice or a glassy deposit from a volcanic eruption. Others said Death Star. Now it turns out your one spot is actually two, and that's supposed to convince us Ceres is harmless? Riiight, nice try. We know the truth -- that you've only just begun to fire up your planet-destroying multi-beam superlaser.
They're baaack... Remember those weird craters that suddenly appeared in Siberia last year? They just showed up in the middle of nowhere, unannounced and unexpected. At the time, scientists got some awesome exploration pictures that don't AT ALL look like they could be the start of a Hollywood horror movie.
The laws of aerodynamics require a certain smoothness of form, a kind of mandatory design elegance. The Piaggio Aerospace Hammerhead stands in contrast to this romantic notion of flight, with canards and pusher propellers combining into an airplane uglier than the sum of its parts. And yet, as Piaggio announced at the International Defence Exposition held in Abu Dhabi, the Hammerhead flies!
Just how scary is the future? In a question posed on Twitter, the Science Friday radio show asked people to come up with #CrimeHeadlinesFrom2025. There were a lot of great responses, running the gamut from copyright law and clones to accidents involving driverless cars. The only problem? Some of the headlines are almost appropriate today. Here are three.
Aussie start-up Threadsmiths have changed the garment world with The Cavalier - a premium white or black cotton t-shirt that uses nanotechnology to repel water and other spills with a hydrophobic coating. But how well does it really work? We raided the kitchen and tested The Cavalier with every liquid we could lay our hands on.
In 2003 Popular Science asked readers: "Will most Americans be driving hydrogen-powered cars by 2015?" The results to that poll are lost to time, but we already know the answer, even if 2015 isn't over yet. Unfortunately, the green technology hasn't been adopted in the past 12 years--but the next decade looks promising.
Ever wonder why you always made a mess of your work clothes while carrying a cup of coffee, while your latte-drinking friends generally manage to keep it together? As it turns out, scientists were also interested in finding out why this happened (perhaps they were frustrated beverage spillers as well). They found that adding foam to the top of a beverage drastically cut down on the spillage that occurred from moving around.
On the morning of March 20, 2015, a solar eclipse will pass over all of Europe, visible from Turkey to Greenland. A decade ago, that probably wouldn't have mattered to anyone except people who love astronomy (and all the schoolchildren building pinhole cameras to observe the sun.) But now, three percent of Europe's electricity grid comes from solar power, making the March event a proving ground for this renewable energy technology.
No one wants to be the first to discover the use of a chemical weapon on a battlefield, but if anyone must have that job, the new Par Chemical Biological Radioactive Nuclear (CBRN) Reconnaissance Vehicle is the car to do it in. Developed by Turkish defense contractor FNSS, the CBRN version is a light armored vehicle ready for the end of the world. Even if its name is a jargony mess.
From 1997 to 2010, the number of Americans with peanut allergies quadrupled. To combat the surge, the American Academy of Pediatrics created guidelines in 2000, suggesting children under the age of 3 should refrain from eating peanuts. In 2008, when this didn't seem to have any impact on the rising number of peanut allergies, the AAP retracted the recommendation. Now, a team of allergists has published a study that flies in the face of those recommendations, arguing that it is actually beneficial to feed peanuts to infants with a high risk of developing the allergy.
