Amphibious Sherp ATV's big wheels keep on turning, no matter the terrain

When we initially saw the Sherp ATV rolling its way around the Internet, our first thought was that it must be the work of a designer, not a real vehicle. The compact body tucked between ginormous off-road tires just looked too odd to be real. But the Russian vehicle is indeed real and it's one hell of a way to drive over anything short of a sheer cliff face.

Stretchable polymer reverts back to original shape when triggered by body heat

Shape memory materials that can revert back into a desired form after being bent, twisted and stretched are finding their way into a number of applications, ranging from sports bras to more efficient refrigerators. One team of scientists is now examining potential biomedical applications, with a polymer that can revert to its original form when it comes into contact with heat from the human body.

Spinning up artificial capillaries with a cotton candy machine

From growing a full thymus gland inside a mouse, to creating a slice of artificial liver tissue, to using ink jet printing technology to create a human ear, researchers are steadily moving us toward the day when ordering up a new organ could be as commonplace as ordering an MRI is today. One of the hurdles in creating lab-grown organs, though, is that the cells in such a structure need a way to receive nutrients. Researchers at Vanderbilt University (VU) may have just leaped that hurdle using a most unexpected tool – a cotton candy machine.

Review: Indian Scout 60 is a worthy mid-weight cruiser

Two things hit you when you ride the new Indian Scout 60 – how quick this mid-weight cruiser is and how really, really uncomfortable the stock seat feels. Roll on the throttle hard and your body lurches back a bit while the bike screams out ahead – and that's in every gear. Plant your back side on that seat for more than 20 minutes and you'll feel like you've been forced to sit for hours on a concrete block wrapped in cardboard.

SteriPen's UVR tech amplifies UV rays to speed up water purification

There are many ways to filter and purify water out in the wild, the MSR Guardian and Oasis being a couple of the most recent we've looked at. Since 1999, Hydro-Photon has gone with ultraviolet light, offering lightweight, compact SteriPen purifiers that quickly zap away microorganisms. With its new Ultraviolet Reflection (UVR) technology, it makes the UV purification process even faster, so outdoor enthusiasts can get clean water more efficiently than ever.

Dangerous bacteria molecules discovered in processed foods

Everyone knows that processed foods aren't exactly good for the human body, but a new study by researchers at the University of Leicester has shed more light on exactly why that's the case. The scientists have detected dangerous molecules called pathogen-associated molecular patterns (PAMPs), which are linked to numerous conditions, including Type 2 diabetes. Perhaps most interestingly, it is believed that the dangerous molecules could potentially be removed without impacting cost or taste.
