SAN FRANCISCO—Clouds can carry millions of pounds of water, but that doesn’t mean rain and snow just happen. Hundreds of thousands of water vapor molecules need to freeze together as ice before they are heavy enough to fall to the ground. But, the water molecules need a bit of dust or other microscopic matter to latch onto in order […]
One of the animal kingdom’s more non-exclusive semantic clubs is that of the worms. Are you “any of a number of creeping or burrowing invertebrate animals with long, slender, soft bodies and no limbs,” as the New Oxford American Dictionary defines you? Well come on in—we have a seat just for you. From the ferocious […]
The western United States is undergoing a major shift in precipitation patterns. Large swaths of the West that have historically been dominated by snow in the winter months are starting to see a lot more rain instead. A new study that maps out the predominant form of precipitation shows that this trend could result in […]
Alone, the simple little robot can’t do much, shuffling around on three vibrating tooth-pick legs. But working with 1,000 or more like-minded fellow bots, it becomes part of a swarm that can self-assemble into any two-dimensional shape. These are some of the first steps toward creating huge herds of tiny robots that form larger structures—including […]
[HTML1] One summer afternoon in 2001, while visiting relatives in India, Subhash Khot drifted into his default mode — quietly contemplating the limits of computation. For hours, no one could tell whether the third-year Princeton University graduate student was working or merely sinking deeper into the living-room couch. That night, he woke up, scribbled something […]
SAN FRANCISCO—Millions of people suffer from facial deformities because an injury, surgery, or birth defect left a gap in their bone structure. These bone gaps are too wide for the body’s normal healing process to fix, and surgical solutions like grafts and putties usually fall short of restoring a person’s looks. But a new sponge-like polymer could provide a scaffold […]
[HTML1] As an 8-year-old, Maryam Mirzakhani used to tell herself stories about the exploits of a remarkable girl. Every night at bedtime, her heroine would become mayor, travel the world or fulfill some other grand destiny. Today, Mirzakhani — a 37-year-old mathematics professor at Stanford University — still writes elaborate stories in her mind. The […]
A chemical sensing company is working on a device that can detect the smell of money.
America has the most ridiculous mythical creatures the world has ever known. Hands down. Nowhere else has a mythology formed so beautifully in a perfect amalgam of too much whiskey, too little sleep, and perhaps some accidentally consumed magic mushrooms.
Lupine Hammack ALLANTOIN The headliner in this gel, which claims to “reduce the appearance” of scars, is allantoin, a nitrogen-rich waste molecule excreted in mammalian urine. It softens keratin, the fibrous protein that makes your birthday suit tough and waterproof. That smooths the skin and encourages dead skin cells to slough off. ALLIUM CEPA BULB […]
Editor’s note: Come back to this post for a live feed of the shower from the Slooh Space Camera starting at 7 p.m. Eastern Time. The Perseid meteor shower is the champion of all such events. Appearing in balmy weather suitable for the most casual stargazer, the meteors dazzle the sky with an average of […]
The two American aid workers getting treated in Georgia for Ebola are isolated in a special ward that some staffers at Emory University Hospital call “Noah’s Ark.” But they’re not the first Americans ever quarantined for Ebola on US soil.
The reason typos get through isn't because we're stupid or careless, it's because what we're doing is actually very smart.
Leon Steele Every 27 minutes, someone in the US dies of an opioid overdose. And all of those 19,500 annual deaths—whether from prescription pain meds or heroin—could be prevented with the fast-acting antidote naloxone. It adheres to the same brain receptors that opioids latch on to, pushing the dangerous drugs aside in five minutes or […]
Scientists strap cameras to the badasses of the sea.
A gallery of images from The Great War From The Air shows the aerial photography that World War I's strategists used to gather intelligence.
Solar power needs get a lot more efficient before it truly goes mainstream. One way to achieve that is with better power inverters—the devices that turn the direct current coming from solar panels and batteries into alternating current you can use in your home to play Xbox and keep your beer cold.

A new iridescent plastic that reveals hidden images with a breath is described in a paper published today in Advanced Materials. Researchers at the University of Michigan hope to use this technology for anti-counterfeiting purposes, replacing the ubiquitous hologram stickers used on things like luxury handbags and passports with a humidity-activated logo.
Ah, Hawaii. The resplendent luaus and awe-inspiring volcanoes. Tom Selleck and his mustache running around private-investigating stuff. The beautiful white-sand beaches made of fish poop. [HTML1] Oh, that’s right. Your precious Hawaiian beach vacation was actually a frolic through epic amounts of doody. Show More Summary
The Aeromedical Biological Containment System used to transport Kent Brantly, the American doctor infected with Ebola, had never been used before. Brantly's flight was its first real test.
