We don't give much love to prairies, but in some places they're disappearing faster than the Amazon. Grass from the past. illustration by Allan Davey Global cleanups pull plastic from oceans and pledge drives guard rainforests, but grasslands get very little love. Only 5 percent of Earth’s remaining meadows are preserved, making them the least-protected biome. Humans have already destroyed more th
Just how unique are partial finger prints? Aditi Roy, Nasir Memon, and Arun Ross Fingerprint readers, like the TouchID on an iPhone, exist to make your device extra secure while keeping the process of unlocking it easy. Computer scientists at New York University and Michigan State are poised to turn that security benefit on its head. Like a master key that can open any lock, these researchers deve
In the wake of post-protest shootings that left five police officers dead and seven others wounded, along with two civilians, police traded gunfire last night with a suspect inside a downtown Dallas parking garage. Eventually, law enforcement sent a “bomb robot” (most likely shorthand for a remotely controlled bomb disposal robot) armed with an explosive, to the suspect’s location, then detonated

One by one, they detailed a mass surveillance program in which the National Security Administration and others gathered information on
The search giant is making its AI open source so anyone can use it In November 2007, Google laid the groundwork to dominate the mobile market by releasing Android, an open source operating system for phones. Eight years later to the month, Android has an an 80 percent market share, and Google is using the same trick—this time with artificial intelligence. Today Google is announcing TensorFlow, it
Mysterious Phony Cell Towers Could Be Intercepting Your Calls Every smart phone has a secondary OS, which can be hijacked by high-tech hackers Like many of the ultra-secure phones that have come to market in the wake of Edward Snowden’s leaks, the CryptoPhone 500, which is marketed in the U.S. by ESD America and built on top of an unassuming Samsung Galaxy SIII body, features high-powered encrypti
Maybe you spent a week in school making these, but the ones in your class almost definitely didn’t look as good. The folks at Pop Chart Lab, which now has an oeuvre of infographics depicting everything from classic games to beer, took a literary turn with their latest chart. A Diagrammatical Dissertation on Opening Lines of Notable Novels (itself one hell of a tongue-twister) is a series of simple
Teaching people game theory is good. Making them live it is even better, says UCLA professor Peter Nonacs. On test day for my Behavioral Ecology class at UCLA, I walked into the classroom bearing an impossibly difficult exam. Rather than being neatly arranged in alternate rows with pen or pencil in hand, my students sat in one tight group, with notes and books and laptops open and available. They

For example, Steve Mahan, who has lost 95 percent of his vision. He becomes Google Autonomous Car Driver #1 in t
How a 14-year-old kid became the youngest person to achieve nuclear fusion This story from the March 2012 issue of Popular Science covered the nuclear fusion experiments of Taylor Wilson, who was then 16. Wilson is currently 28 and a nuclear physicist who’s collaborated with multiple US agencies on developing reactors and defense technology. The author of this profile, Tom Clynes, went on to write
The Sealander amphibious trailer is the camping accessory of our 1970s PopSci dreams come to life, except better than we ever imagined. This super-light trailer is tiny enough that it can be towed even by subcompact cars without a special permit, extra mirrors or gear, and serves as a kitchen, a tent and a boat. Inside the customizable Sealander (which will be available for purchase in 2012), seat

Today at the National Meeting of the American Chemical Society researchers from MIT’s Nocera Lab, led by Dr. Daniel Nocera, claimed
Superhero-Style Spacesuits Could Provide Vital Compression For Astronauts This new Spiderman-style suit may not win astronauts a spot in the fashion hall of fame, but it could help keep their bones intact during long spaceflights. Described in a new paper, prototype tests of the Gravity Loading Countermeasure Skinsuit, being developed by a research team at MIT’s Man-Vehicle Laboratory, show that t
In a new study, researchers report that bumblebees were able to figure out the most efficient routes among several computer-controlled "flowers," quickly solving a complex problem that even stumps supercomputers. Queen Mary, University of London We already know bees are pretty good at facial recognition, and researchers have shown they can also be effective air-quality monitors. Here’s one more re
My hand is like a red-hot poker to the liquid nitrogen, but an insulating layer of nitrogen gas forms- a phenomenon known as the Leiden-frost effect- keeping my hand safe and warm for a fraction of a second. Mike Walker When I first saw this photograph of a man’s hand submerged in liquid nitrogen at somewhere below -320° F, my immediate thought was, “That guy must be crazy! One second in that stuf
Video: “Smart Sheets” Can Self-Assemble Into Airplanes, Boats Scientists at MIT and Harvard have invented self-folding smart fiberglass sheets that can crease themselves into origami airplanes and boats. It’s a far cry from previous programmable matter research we’ve seen, which works at the nanoscale to create scaffolds and gears. The fiberglass sheets are about a half-millimeter thick and made o
The Hayabusa spacecraft landed in the Australian outback on June 13, after a seven-year space journey. It is the hope of JAXA, Japan’s space agency, that the capsule Hayabusa is carrying contains a sample taken from asteroid Itokawa. If so, this will be the first sample of asteroid material ever returned to Earth by a space mission. Now, the process of opening the capsule to see what’s inside has
Japan Plans a Moon Base by 2020, Built by Robots for Robots America may have eighty-sixed its moon base ambitions, but the Japanese have no plans to let perfectly good lunar real estate go to waste. An ambitious $2.2 billion project in the works at JAXA, the Japanese space agency, plans to put humanoid robots on the moon by 2015, and now official backing from the Prime Minister’s office says the J

Innovation manifests itself in myriad ways: groundbreaking, revolutionary bursts we'd never before imagined possible, or in more nuanced but no less brilliant refinements of existing technology. And while this year's list contains plenty of instances of the former, in compiling it we've noticed one thing: 2009 is the year of stealth innovation. Innovation manifests itself in myriad ways: groundbre
svg]:stroke-transparent [&>svg]:fill-accent-900 mr-2 relative top-0.5"> Ferrofluids are made up of tiny magnetic fragments of iron suspended in oil (often kerosene) with a surfactant to prevent clumping (usually oleic acid). The fluid is relatively easy to make at home, yet extremely expensive to buy online. How does $165 a liter sound? Pretty bad, right? Read on to learn how to make ferrofluids o
A man-made, pure-white compound called Oxycyte carries oxygen 50 times as effectively as our own blood. Researchers are betting that it’s the best way to treat America’s leading cause of accidental death: traumatic brain injury Grace LeClair had just finished eating dinner with friends when she got the phone call every parent dreads. The chaplain at the Medical College of Virginia was on the o
Nearly five decades ago, Americans learned that one of their most treasured habits—smoking—was lethal. This year, we could get more scary news, when scientists announce the results from Interphone, the largest-ever study to investigate whether cellphones cause cancer. Interphone researchers are pooling and analyzing the results gathered from studies on 6,400 tumors sampled from patients in 13 coun
