Something to ponder …

… while spending half the day on the cell.

It’s doing something.

From the link:

Radiation from a mobile phone call can make brain regions near the device burn more energy, according to a new study.

Cellphones emit ultra-high-frequency radio waves during calls and data transfers, and some researchers have suspected this radiation — albeit inconclusively — of being linked to long-term health risks like brain cancer. The new brain-scan-based work, to be published Feb. 23 in the Journal of the American Medical Association, shows radiation emitted from a cellphone’s antenna during a call makes nearby brain tissue use 7 percent more energy.

One more thing to do this Sunday — check out the sun

NASA Releasing First Views of the Entire Sun on Super SUN-Day

WASHINGTON, Feb. 4, 2011 /PRNewswire-USNewswire/ — NASA will score big on super SUN-day at 11 a.m. EST, Sunday, Feb. 6, with the release online of the first complete view of the sun’s entire surface and atmosphere.

Seeing the whole sun front and back simultaneously will enable significant advances in space weather forecasting for Earth, and improve planning for future robotic or crewed spacecraft missions throughout the solar system.

These views are the result of observations by NASA’s two Solar TErrestrial Relations Observatory (STEREO) spacecraft. The duo are on diametrically opposite sides of the sun, 180 degrees apart. One is ahead of Earth in its orbit, the other trailing behind.

Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. The mission observed the sun in 3-D for the first time in 2007. In 2009, the twin spacecraft revealed the 3-D structure of coronal mass ejections which are violent eruptions of matter from the sun that can disrupt communications, navigation, satellites and power grids on Earth.

STEREO is the third mission in NASA’s Solar Terrestrial Probes program within the agency’s Science Mission Directorate in Washington. NASA’s Goddard Space Flight Center in Greenbelt, Md., manages the mission, instruments and science center.

The Johns Hopkins University Applied Physics Laboratory in Laurel, Md., designed and built the spacecraft and is responsible for mission operations.

The STEREO imaging and particle detecting instruments were designed and built by scientific institutions in the U.S., UK, France, Germany, Belgium, Netherlands and Switzerland.

I know I said there would be light blogging …

… but I had no idea it’d be this light.

Been crazy busy with projects to the point I didn’t even blog about the NFL playoffs so far. No guarantees, but I expect to get back into this saddle a bit more regularly. I’ve missed a ton of cool nanotech and invisibility cloaking stuff, not to mention business news and two major events in North Africa.

I’m back (at least partways.)
