If you’re considering switching to kale, think again: Romaine likely isn’t any riskier than other leafy greens. Spinach and other lettuce varieties are similarly vulnerable to a harmful E. coli strain, says Purdue University food science professor Amanda J. Deering. The reason romaine has been plagued by E. Coli more than other greens has more to do with its popularity. The more romaine, the more infections. If you feel like romaine recalls have escalated, you aren’t wrong....

With smoldering wreckage still being collected from the crash site, the Navy said it is too early to determine the cause of the crash. According to Marine Corps spokesperson Corporal Francis Goch, the plane, an F/A-18D Hornet, was returning from training when the pilot radioed air traffic control about a problem, ejecting shortly thereafter. “He radioed into air traffic control, he said he didn’t know what the problem was,” said Goch....

The Sustainable Agriculture Flagship in Australia will install winged, wireless electronics with infrared sensors in cows’ digestive tracts to monitor how much methane the animals are releasing. With that data, they can alter their diets to the most eco-friendly palette. And thanks to the wings, the devices will stay in the cows for weeks, sending plenty of info back to researchers. Ideally the researchers will have a device in the cow at all times....

Fears of the doomsday scenario of what would happen if this volcano were to erupt in the present day have sparked debate and worry about what is going on beneath the feet of the millions of tourists who visit the park every year. The scientists who study the volcano say we will receive decades worth of warnings that an eruption is about to happen, likely won’t occur for thousands of years, and the volcano is not overdue for an eruption....

Another thing often missing from yoga pictures? Sweat. If you find yourself frequently using a towel to wipe off your mat and keep your hands or feet from slipping, this yoga towel will be a huge improvement. At 68 inches long and 24 inches wide, it covers the majority of the average mat. The polyester blend material is designed to absorb sweat, wick it away from your body, and dry quickly....

This is the first public beta Apple is offering for watchOS. Typically, it’s simple to get an early look at macOS, iOS, and iPadOS software, but Watch users typically have to wait for final code to ship. As with any pre-final software, installing it on a device you rely on every day is ill-advised since there are still bugs lurking in places you may not expect. But, Apple is confident enough in it to extend the beta beyond the developers....

“Our results suggest that the small trees are actually quite resilient,” says study author David Bartholomew, a PhD candidate at the University of Exeter’s Global Systems Institute. Bartholomew and his colleagues studied 30 small trees in the drought half of the experimental area, and a further 36 from the non-drought half, conducting a number of tests to learn more about the trees. They studied the dimensions of the trees as well as their position in the canopy hierarchy, and they collected branches to study the leaves of each tree....

How secure are your passwords? How often do you sign up for a new account with every intention to cancel after securing an introductory offer, only to totally not do that? How many emails from the same retailers do you delete every day? Do you type with your palms floating because your overworked laptop scorches like the sun’s core? Nobody wants to tackle all those problems at once. But if someone compiled a list of all the cleanup tasks you need to knock out, and emailed you a tutorial for one each day?...

With a recent study showing bacteria live on the surface of the eye and stimulate protective immunity, scientists are beginning to discover the microbial factors that can be exploited to create innovative therapies for a range of eye disorders like Dry Eye Disease, Sjogren’s Syndrome and corneal scarring. One day it may be possible to engineer bacteria to treat eye diseases in humans. I’m an immunologist studying how the eye prevents infection....

Directed by Duncan Jones (David Bowie’s son and director of Moon and Source Code) and starring Ben Foster, Dominic Cooper, and Travis Fimmel, the Warcraft movie does not stray far from the land of Azeroth. The Dark Portal is still open, and the Horde continues to battle the Alliance for control to ultimately set the fate of civilization. Other than the inherent excitement of finally seeing the game on the big screen, some of the trailer’s scenes feel like lost footage from Peter Jackson’s Lord of the Rings trilogy, so here’s to hoping for a bit more substance and originality when the flick debuts in June 2016....

It was, for a time, displayed as a part of the auto-icon. But after multiple thefts by students, it was locked away and it’s no longer available to be seen by the public....

Titan is the successor to ORNL’s Jaguar supercomputer (actually, it’s really an upgrade of Jaguar), which itself sat atop the TOP500 rankings a few years ago. Since then, computers in China, Japan, and elsewhere have really given the U.S. a serious run for its money, unseating Jaguar for the number one position and pushing other systems down the rankings at times. For ORNL and the U.S. Department of Energy, it has to be nice to have two separate systems sitting in the top two spots on the TOP500....

Whether you’re a vegetarian, vegan, pescatarian, flexitarian, so something completely different, you might think a lot about how the foods you eat alter the planet. But unlike other major activities linked to climate change, the answer isn’t always so clear-cut. Sustainability labels can be confusing, and there’s a lot more than just carbon emissions to account for when it comes to making sure your food is an ethical win. Still, there are a few surefire ways to dine well and still protect the planet....

The first-place photo (above) is the foot of an embryonic lizard—Phelsuma grandi, a Madagascar giant day gecko—created by Grigorii Timin at the University of Geneva under the supervision of biologist Michel Milinkovitch. Hundreds of images, representing 200 gigabytes of data, were stitched together to show nerves (in cyan), bones, blood cells, and other tissues. Even though the foot is only about 3 millimeters long, acquiring all those images took more than two days, Timin said in a news release....

Instead of creating a flat strip of material and bending it into a shape like a Mobius strip, the gigantic D-Shape printer will make pieces of the 12,000-square-foot building, spitting out 6-by-9-meter section that will eventually be assembled into the full building. (The printer’s inventors want to use it to print houses on the moon eventually, so this is a nice warmup.) A mixture of sand and a binding agent will make the frames of the structure, and each frame will be filled with fiberglass and concrete....

Going after flavored e-cigarettes makes sense because survey results show that flavors are a main reason high school students vape, says Richard Miech, a principal investigator of an ongoing study on behaviors and attitudes of high school students based at the University of Michigan. According to the study’s 2015 data, the primary reason that kids vaped was out of curiosity. “The second highest reason was that they liked the flavors,” he says....

Six days before: Review existing advice Five days before: Write your shopping list Sure, you’ll want to treat yourself to a few surprises over the Black Friday weekend.
