Our smartphones and other gadgets are powered by lithium-ion batteries, but as companies like Samsung know all too well, those charge-holders can be flammable under the wrong conditions. The hazards of lithium-ion batteries are also a concern for another group, one with a strong incentive to keep fires at bay: the U.S. Navy. Now chemists at the U.S. Naval Research Laboratory (NLR) have announced a new battery technology that they say is both safe and rechargeable, and could make its way into electric vehicles, bikes, or ships.
Just last month, Amazon introduced a Prime feature called Outfit Compare which let users upload a pair of selfies showing different outfits to be evaluated by style experts. Today, Amazon has doubled down on its push to guide the style of everyday users with its home assistant and fashion guru, the $200 Echo Look, which can currently only be ordered by invitation.
So, the Pentagon used a massive bomb against caves in eastern Afghanistan that currently house ISIS fighters, and previously housed insurgents fighting against British rule in the 19th century and mujahadeen fighting against Soviet control in the 20th century. For centuries, the caves of Afghanistan have made it difficult for outsiders to control the country. But in the early 21st century, the United States considered developing a brand new weapon to nullify these ancient defenses. The “Robust Nuclear Earth Penetrator” was an earthquake in a can, a nuclear bomb designed to seal the caves once and for all.
There's a rush right now for clothing companies—especially those in the outdoor and athletic spaces—to find renewable materials for their wares. Reebok has chosen corn as its preferred sustainable building block for use in an upcoming sneaker, which is part of its Corn + Cotton initiative.
Airplane passengers are in for an increasingly bumpy ride according to a study released today in the journal Advances in Atmospheric Sciences. Climate change is altering the jet stream, making severe turbulence more likely. The study builds on earlier work which found that climate change would lead to bumpier airplane rides. What makes the new research unique is that it quantifies how much different kinds of turbulence will increase—59 percent in the case of light turbulence, a 94 percent increase in moderate turbulence, and 149 percent increase in severe turbulence.
