Mobile Medical Lab — the $10 Phone Microscope 54

kkleiner writes "Aydogan Ozcan of UCLA has developed a microscope attachment for a cell phone – turning the device into a sort of mobile medical lab. It's both lightweight (~38g or 1.5 oz) and cheap (parts cost around $10). The cellphone microscope can analyze blood and saliva samples for microparticles, red blood cells, white blood cells, platelets, and water borne parasites. Ozcan and his team have recently won three prestigious awards for the device: a Grand Challenges award from the Bill and Melinda Gates Foundation (worth $100,000), the National Geographic Emerging Explorer award (worth $10,000), and the CAREER award from the National Science Foundation ($400,000). With these funds, Ozcan plans on starting case studies in Africa to see how the microscope can help revolutionize global medicine."

Decades-Old Soviet Reflector Spotted On the Moon 147

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

Seinfeld's Good Samaritan Law Now Reality? 735

e3m4n writes "The fictitious 'good samaritan' law from the final episode of Seinfeld (the one that landed them in jail for a year) appears to be headed toward reality for California residents after the house passed this bill. There are some differences, such as direct action is not required, but the concept of guilt by association for not doing the right thing is still on the face of the bill."

Comment Re:Learning German (Score 1) 450

I studied German at the Goethe Institute. See http://www.goethe.de/ins/us/enindex.htm/ for a list of U.S. locations. They have locations worldwide. This is from 25 years ago in London, but the instructors were first-rate, and the cost was low. I took two months full-time and it was enough to get me started in Germany where I was working. During the training, I started getting headaches as my brain rewired, and I couldn't speak English or German properly for awhile. I took advanced German in Abendschule for a couple of years and passed the German language entrance exam at the Free University. Here's a tip - when you're memorizing nouns, always learn the gender of the noun. When you get to Germany, speak as little English as possible for awhile. Since so many people speak decent English, it's tempting not to make the effort to speak German. Start reading challenging publications like Der Spiegel. This will also get you up to speed on what's going on in Germany which will impress your German contacts. Good luck! Tom
