Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

0xdeadbeef writes "Two weeks ago, MIT artist-in-residence Joe Davis used the Arecibo radio telescope to send a message to three stars in honor of the 35th anniversary of the famous Drake-Sagan transmission to M13 in 1974. It was apparently allowed but not endorsed by the director of the facility, and used a jury-rigged signal source on what will now be known as the 'coolest iPhone in the world.' The message encoded a DNA sequence, but no word yet on whether it disabled any alien shields. You can get the low-down on Centauri Dreams: Part 1, Part 2."

suraj.sun sends along this quote from an Associated Press report: "Opening a government meeting on auto safety, the Obama administration reported Wednesday that nearly 6,000 people were killed and a half-million injured last year in vehicle crashes connected to driver distraction, a striking indication of the dangers of using mobile devices behind the wheel. The Transportation Department was bringing together experts over two days for what it's calling a 'distracted driving summit' to take a hard look at the highway hazards caused by drivers talking on cell phones or texting from behind the wheel. ... Driver distraction was involved in 16 percent of all fatal crashes in 2008. Eighteen states and the District of Columbia have passed laws making texting while driving illegal and seven states and the district have banned driving while talking on a handheld cell phone, according to the Insurance Institute for Highway Safety. Many safety groups have urged a nationwide ban on texting and on using handheld mobile devices while behind the wheel."

FleaPlus writes "Apollo 11 astronaut (and MIT Astronautics Sc.D.) Buzz Aldrin suggests a bolder plan for NASA (while still remaining within its budget), which he will present to the White House's Augustine Commission; he sees NASA heading down the wrong path with a 'rehash of what we did 40 years ago' which could derail future exploration and settlement. For the short-term, Aldrin suggests canceling NASA's troubled and increasingly costly Ares I, instead launching manned capsules on commercial Delta IV, Atlas V, and/or SpaceX Falcon 9 rockets. In the medium-term, NASA should return to the moon with an international consortium, with the ultimate goal of commercial lunar exploitation in mind. Aldrin's long term plan includes a 2018 comet flyby, a 2019 manned trip to a near-earth asteroid, a 2025 trip to the Martian moon Phobos, and one-way trips to colonize Mars."

Marten writes "It was more than a year ago that Walter Bender left OLPC and started SugarLabs.org. Now, the first version of the new project has been released. Sugar on a Stick is a USB drive that runs on Mac and PC-style hardware. 'The open-source education software developed for the "$100 laptop" can now be loaded onto a $5 USB stick to give aging PCs and Macs a new interface and custom educational software.' Bender said, 'What we are doing is taking a bunch of old machines that barely run Windows 2000, and turning them into something interesting and useful for essentially zero cost. It becomes a whole new computer running off the USB key; we can breathe new life into millions of decrepit old machines.'"
