Mitt Romney works Thursday in Michigan aboard his campaign bus, which displays a poster for his late father, former Michigan Gov. George Romney. Despite deep roots in the state, Romney finds himself battling a candidate who has barely visited.
By the time Rick Santorum showed up in Michigan, he was already out in front.
Thursday's speech before the Detroit Economic Club amounted to the former Pennsylvania senator's political debut in the state, coming less than two weeks before Michigan votes in a Feb. 28 Republican primary.
Nonetheless, Santorum arrived in the state sitting at the top of the polls. It's a big break from the way things used to be.
Thanks to its strategic location, the small Central Asian country of Azerbaijan has long been a hot spot for rival intelligence agents, from countries such as Russia, Turkey, Iran and Israel. Here, a view of Baku, the capital, in June 2011.

Iranian President Mahmoud Ahmadinejad (right) meets with Azerbaijan's foreign minister, Elmar Mammadyarov (left) in Tehran in March 2011. Tensions have been growing between the countries, including a recent incident in which Tehran summoned the Azerbaijani ambassador to protest alleged Israeli intelligence activity in Azerbaijan.
The small Central Asian country of Azerbaijan has found itself caught up in the rising international tensions over neighboring Iran and its nuclear program. Despite traditional ties with Iran, the former Soviet republic has increasingly aligned itself with the West, and with Israel.
An incident at a recent soccer match in the Iranian city of Tabriz is still a point of pride in Azerbaijan. In the middle of the match, hundreds of ethnic Azeris in the crowd broke out their national flags and began to chant that the city belongs to them.
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.
This is SCIENCE FRIDAY. I'm Ira Flatow. Some good news for the nuclear industry. The Nuclear Regulatory Commission licensed the construction, issued licenses for the construction, of two nuclear reactors at a plant in eastern Georgia. Until last week, the NRC hadn't approved the construction of any new reactors in the U.S. since 1978. That was a year before the partial reactor meltdown at Three Mile Island in Pennsylvania.
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.
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.
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.
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.
