Boeing creates self-cleaning, germ-zapping lavatory for airliners

One of the drawbacks of flying is that you're sharing the lavatory with a couple of hundred people of unknown hygiene standards, and the thing won't be properly cleaned again until the plane touches down. To make the airborne germaphobe a bit more comfortable and the facilities more hygienic, Boeing has created a self-cleaning airliner lavatory that uses non-touch technology and ultraviolet light that's claimed to kill 99.99 percent of germs in three seconds.Read More

UBSafe tells you when to seek the shade

A new UV-monitoring device may help take some of the guesswork out of knowing how much time to spend in the sun. Developed by Australia's Healthtronics Sunsafe, the UBSafe come in three different models, and is attached to a hat or other headwear. From that location, it can tell you when your particular skin type has had just the right amount of UVB rays.Read More

GermFalcon robot is made to sanitize airliners

Airliner cabins can get pretty germy. They're packed full of people from all over the world, who spend hours doing things like coughing, sneezing and touching surfaces with their grubby li'l hands. It was with this in mind that Arthur Kreitenberg and his son Mo created the GermFalcon. It's a robot that kills germs on planes, using ultraviolet light.Read More

Panasonic’s new technology purifies water with sunlight and photocatalysts

Drinking clean water is something that many people in the world can't take for granted, as they rely on polluted sources and often have no access to purification systems. In response to that problem, Panasonic is developing a new technology that looks to the sun to clean water extracted from the ground. The company recently presented a system that uses sunlight and photocatalysts to purify polluted water at a high reaction rate, to improve access to clean water where it's needed. Read More

Scientists developing drug that could prevent sun-related aging of skin

Excessive exposure to sunlight is the leading cause of skin deterioration, causing it to age prematurely. We need some exposure, however, in order to synthesize vitamin D – plus who wants to stay in the shade all the time? Using a good sunscreen definitely helps, although scientists from the University of British Columbia are taking things a step farther – they're developing a drug that could ultimately prevent the sunlight-related aging of skin.

NASA releases stunning global maps of six of Saturn's moons

NASA has released global maps of six of the Saturnian moons. The system has been under the intense examination of the Cassini-Huygens mission for the past decade, and the completion of the global maps represents the end of one of the legendary spacecraft's key mission objectives. Almost all of the maps are whole, though there are currently parts of Iapetus unfinished, as well as a region of the north pole of Enceladus set to be filled in some time next year.Read More

Bondic takes a "light" approach to sticking things together

Perhaps you've had one or more of the following experiences when trying to stick items together using super glue: the glue sets before the objects can be properly aligned, it won't set fast enough, or it hardens inside the bottle once it's been opened. Well, Bondic is claimed to have none of those problems. It's described as a "liquid plastic welder" that sets within four seconds, but only once it's been exposed to an included UV light.Read More

Xenex updates protocols for germ-zapping robots in response to Ebola threat

Dealing with highly infectious diseases like Ebola is often like a logic problem. Disinfecting rooms is hard enough, but what about protective suits? True, they greatly reduce the chances of infection, but getting them off can bring the risk straight back again if the suit isn't decontaminated first. Xenex has created protocols that conform to those of the US Centers for Disease Control and Prevention (CDC) for its a line of robots that use UV lamps that to decontaminate hospital rooms and protective clothing exposed to the Ebola virus.Read More

Silicon Valley's latest high-tech gadgetry makes sewage water drinkable

Drinking recycled urine may be the stuff of Dune novels, and a drastic response to California’s ongoing drought. But officials in Santa Clara County in the heart of Silicon Valley are hoping its new high-tech purification plant will help residents get past the ick factor and eventually allow treated wastewater to flow through their faucets in a "toilet to tap" scenario. Opened in July, the $72 million Silicon Valley Advanced Water Purification Center is the most advanced such plant in the US, and uses a multi-step system of microfiltration, reverse osmosis and ultraviolet rays to produce water of higher quality than typical drinking water.Read More

Transparent solar collectors may replace conventional windows

Researchers working at Michigan State University have created a completely transparent solar collector which is so clear that it could replace conventional glass in windows. The new devices – dubbed transparent luminescent solar concentrators – have the potential to not only turn windows into solar electric generators, but the screens of smartphones, vehicle glazing, and almost anything else that has a see-through surface.Read More
