Mobile phone breath test can check for signs of cancer

The disease breathalyser is not new. The concept has been around for a few years and evenToshiba¬†has come up with a gadget that can ‘smell’ acetone, an indicator of diabetes. But researchers at Owlstone Technologies in the UK are developing a miniature breasthalyser that can be adapted to mobile phones and help doctors identify

Living human cartilage grown on lab chip

In a significant step toward reducing the heavy toll of osteoarthritis around the world, scientists have created the first example of living human cartilage grown on a laboratory chip. The researchers ultimately aim to use their innovative 3-D printing approach to create replacement cartilage for patients with osteoarthritis or soldiers with battlefield injuries.

“Osteoarthritis has a severe impact on quality

Coldest Star Is Close Neighbor of Our Sun

A brown dwarf” star that appears to be the coldest of its kind — as frosty as Earth’s North Pole — has been discovered by a Penn State University astronomer using NASA’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes. Images from the space telescopes also pinpointed the object’s distance at 7.2 light-years away, making it the fourth closest system to our Sun.

“It is very exciting to discover a new neighbor of our solar system that is so close,” said Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State and a researcher in the Penn State Center for Exoplanets and Habitable Worlds. “In addition, its extreme temperature should tell us a lot about the atmospheres of planets, which
