goG sends in a piece from IBTimes on the latest study to confirm what is becoming pretty obvious. The article mentions the Internet addiction rehab center we discussed last year. "American college students are hooked on cellphones, social media and the Internet and showing symptoms similar to drug and alcohol addictions, according to a new study. Researchers at the University of Maryland who asked 200 students to give up all media for one full day found that after 24 hours many showed signs of withdrawal, craving and anxiety along with an inability to function well without their media and social links. ... 'Texting and IM-ing my friends gives me a constant feeling of comfort,' wrote one of the students, who blogged about their reactions. 'When I did not have those two luxuries, I felt quite alone and secluded from my life.'"

coondoggie writes "NASA this morning used a United Launch Alliance Atlas rocket to blast its 6,800lb Solar Dynamics Observatory into an orbit 22,300 miles above Earth. The $808 million spacecraft will ultimately study the Sun and send back what NASA called a prodigious rush of pictures about sunspots, solar flares and a variety of other never-before-seen solar events. The idea is to get a better idea of how the Sun works and let scientists better forecast the space weather to offer earlier warnings to protect astronauts and satellites, NASA said."

Gulthek writes "Sixteen-year-old Alexander Kendrick has created a device that allows texting and other data transfer from almost 1000 feet underground. The tech could allow rapid emergency communication with the surface and opens the potential for scientific measurements without the need to continually visit (and disturb) the cave environment." There's some kvetching in the NPR story's comments that it's not the first use of cave radios, but that seems to miss the point.

pjt33 notes a recently published paper proposing that ocean currents could account for Earth's magnetic field. The wrteup appears on the Institute of Physics site; the IOP is co-owner, with the German Physical Society, of the open-access journal in which the paper appears. This reader adds, "The currently predominant theory is that the cause of Earth's magnetic field is molten iron flowing in the outer core. There is at present no direct evidence for either theory." "Professor Gregory Ryskin from the School of Engineering and Applied Science at Northwestern University in Illinois, US, has defied the long-standing convention by applying equations from magnetohydrodynamics to our oceans' salt water (which conducts electricity) and found that the long-term changes (the secular variation) in the Earth's main magnetic field are possibly induced by our oceans' circulation."

dooberrymctavish writes "Ghostwalker over at AndroidFanatic has gone and done it again; now he's released clear and concise instructions on how to get X11 server running on your Android device. Not only that, but he has successfully gotten LXDE, and IceWM running at a pace. There is even a photo with the instructions showing the LXDE desktop running right there on the device itself. Apparently, you can also VNC straight onto the phone's new desktop from your PC."

xufem writes "Millions of Brazilian schoolchildren will soon be 'brought up right' running Linux on over 350,000 seats each using PC sharing hardware and software from Userful and KDE. This is world's largest virtual desktop deployment and probably also the world's largest Linux deployment, and seems to have been selected over OLPC by Brazil. Definitely a moment to celebrate — and just in time for Brazilian Carnival which starts tomorrow!"
