Something to ponder …

… while spending half the day on the cell.

It’s doing something.

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.

Obama ends stem cell restrictions

Hallelujah, let the light of basic science shine on.

From the link:

President Obama will announce Monday that he is reversing Bush administration limits on federal financing for embryonic stem cell research as part of a pledge to separate science and politics, White House officials said Friday.

As a presidential candidate, Mr. Obama spoke out in favor of stem cell research, so his intention to undo the curbs put in place by President George W. Bush is not surprising. But the decision is nonetheless of great interest, involving a long-controversial intersection of science and personal moral beliefs.

The officials said that advocates of unfettered stem cell research, as well as about 30 Democratic and Republican lawmakers who support it, had been invited to a White House ceremony scheduled for 11:45 a.m. Eastern time, when Mr. Obama is expected to make an announcement.

One person familiar with planning for the event said the president would also speak about a general return to “sound science” in his administration, as a fulfillment of his campaign promise to draw a demarcation line between politics and science. The Bush administration was often accused of trying to shade, or even suppress, the findings of government scientists on climate change, sex education, contraceptives and other issues, as well as stem cells.
