In California's Central Valley, authorities are excavating the gruesome remains of an unknown number of murder victims who were buried many years ago by a pair of convicted murderers and drug users.

The search began last week after one of the convicts agreed to lead authorities to the remains in exchange for cash.

But, the case raises some thorny ethical and legal issues: Should convicted criminals be able to benefit from their wrongdoing?

Now that Congress has passed the extension of the payroll tax cut and jobless insurance benefits for the long-term uninsured, as well as a fix that prevents cuts in Medicare reimbursements to doctors, there's the sense that not much else will get done on Capitol Hill, it being a general-election year and all.

Journalists don't talk about the danger. They don't usually recount the moments of agonizing terror that come after a bad decision to continue on down the road as the faint sound of mortar shells grows louder.

Women living with HIV, or at high risk of infection, should continue to use hormone injections to prevent pregnancy, the World Health Organization said Thursday.

But the advice stressed that couples should use an additional protective method, like condoms, to prevent HIV transmission between partners.

Multiple news outlets are reporting that federal authorities have arrested a man who thought he was about to undertake a suicide bombing attack on the U.S. Capitol.

Fox News, which broke the story, reports the man was arrested in Washington on Friday, after a lengthy investigation by the FBI. At the time the man was wearing a vest he thought was packed with explosives but was really provided by FBI agents he thought were al-Qaida associates.

News Corp. CEO Rupert Murdoch isn't backing down.

In an email to staff of the besieged Sun tabloid, where ten current and former senior staff have been arrested since November, the 81-year-old media tycoon promised to "build on the Sun's proud heritage by launching the Sun on Sunday very soon.

The email came as Murdoch visited the paper's U.K. headquarters for a meeting with staff. According to the BBC:

New York Knicks guard and Harvard University alumnus Jeremy Lin may be a sudden NBA sensation, but the men's basketball team at his alma mater is making its own mark on the national scene.

Harvard is currently on top of the Ivy League basketball standings. And with a 21-3 overall record and some impressive nonconference wins, the Crimson spent part of the season in the Top 25 in national polls for Division I.

There's a palpable buzz about the team, as well — even a late January road game against the struggling squad from Brown University was a sellout.

Writing in the journal Nature, UCSF pediatrician Robert Lustig and colleagues suggest regulating sugar just like alcohol and tobacco--with taxes and age limits, for example--due to what they call the "toxic" effects of too much sweet stuff. Education, they say, is not enough.

Two studies in the Archives of Internal Medicine suggest short and long-term exposure to air pollution can increase the risk of stroke and cognitive declines. Study author Jennifer Weuve discusses the results, and why particulate matter and gases like ozone may harm the body.

Duke biologist Sarah Zylinski wants to better understand how cuttlefish see the world. Like their relatives octopus and squid, cuttlefish are master camouflagers--and Zylinski says you can learn something about how they process visual information by testing how they change their skin patterns in relation to different backgrounds.

Federal regulators signed off on the construction and operation of two nuclear reactors at a Georgia plant. It's the first license to be granted for a new reactor in the U.S. since 1978. Nuclear expert Per Peterson discusses the reactors' design, safety features and what this means for the future of nuclear power.

In his book Concrete Planet, author Robert Courland discusses why the concrete first used by the Romans is more durable than the concrete used in most present day buildings. Plus, mineralogist Peter Stemmerman tells us about his invention, Celitement and why it is greener than Portland cement.

Linguist David Harrison has travelled to remote corners of the world seeking the last speakers of endangered languages. Now, he's using digital tools to to record and revitalize these dying languages. At the AAAS meeting this week, Harrison unveiled 'talking dictionaries' for eight languages.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY. I'm Ira Flatow. Last week, the government approved the first new nuclear reactor power plants in over 30 years, but in the meantime, the Department of Defense has been investigating a different energy source for its military bases: solar.

My next guest says the military could install seven gigawatts of solar power on its bases. That's roughly equivalent to the output of seven nuclear power plants, and that's all without interfering with bombing ranges or rocket tests and of course the desert tortoise.

If you've been in New Orleans for carnival season, or if you're lucky enough to taste a cake that has arrived in the mail from there, there's a pretty good chance that yes, there is a plastic baby that comes with your cake.

The baby, meant to represent Jesus, has become a fixture of the king cake (galette des rois in France or rosca de reyes as it's called in Mexico). It's a frosted yeast dough cake that New Orleans bakeries churn out between King's Day, January 6^th, and Fat Tuesday, the last day of indulgence before Lent.

While pretty much any corner of Benghazi is a fine place to celebrate this week, the heart of the celebrations are taking place at the courthouse and its public square, where some of the revolution's first protests took place.

Proview Technology is threatening to take Apple to court to seek $2 billion in compensation, because the company says it owns the iPad name in China.

CNET reports:

More horrific reports out of Homs only a day after the United Nations General Assembly called on President Bashar al-Assad's regime to end its shelling of the city.

Voice of America reports activists say:

... tank fire and artillery shelling hit four neighborhoods in the central protest city Friday which has spearheaded the 11-month uprising.
