Behold the iPhone as hi-def medical imaging device

A team of physicists and engineers out of the University of California at Davis are taking the iPhone 4 to new heights--and they're not talking about No. 5.

Using materials that cost about as much as a typical app, they tricked out an iPhone with a few new tools, including a microscope, which--with the phone's camera--could identify features as small as 1.5 microns. That's small enough to identify different blood cell types.

"Field workers could put a blood sample on a slide, take a picture, and send it to specialists to analyze," says Sebastian Wachsmann-Hogiu, a physicist at the Center for Biophotonics, Science and Technology and lead author of the research to be presented in mid-October at the Optical Society's Annual Meeting in San Jose, Calif.

In rural clinics in developing nations, which tend to have limited if any lab equipment, these decked-out iPhones could help nurses and doctors diagnose a range of blood diseases by not only imaging blood cells but sending data in real time to colleagues anywhere around the world for further analysis.… Read more

Astronauts attach cosmic ray detector to space station

KENNEDY SPACE CENTER, Fla.--The Endeavour astronauts installed a $2 billion cosmic ray detector on the International Space Station today, a powerful magnet surrounded by a complex array of sensors that will study high-energy particles from the depths of space and time to look for clues about the formation and evolution of the universe.

"Thank you very much for the great ride and safe delivery of AMS to the station," radioed Sam Ting, the Nobel laureate who has managed the Alpha Magnetic Spectrometer project for more than 15 years. "Your support and fantastic work have taken us … Read more

Endeavour glides to 'silky-smooth' station docking

KENNEDY SPACE CENTER, Fla.--With commander Mark Kelly at the controls, the shuttle Endeavour caught up with the International Space Station early today, looping under and then ahead of the lab complex before gliding back to a "silky smooth" docking at the station's forward port at 6:14 a.m. EDT.

"Houston and station, capture's confirmed," pilot Gregory Johnson radioed as the two spacecraft sailed through orbital darkness 220 miles above the south Pacific Ocean.

Inside the space station, European Space Agency astronaut Paolo Nespoli rang the ship's bell in a traditional naval … Read more
