This is SCIENCE FRIDAY. I'm Ira Flatow. You've seen the movies: A killer asteroid approaching the earth. Cue the dramatic music. Hollywood heroes - James Garner's my favorite - to save the day. But in order to stop an asteroid, first you need to be able to find it, track it, and maybe even know a bit more about asteroids, so you have a better chance of dealing with it successfully.

MERS Virus Update

Jul 26, 2013

Middle East Respiratory Syndrome (MERS) is an illness caused by a newly discovered virus in the same family as SARS. Most of the documented cases have come from Saudi Arabia, which has seen a 54 percent mortality rate in those patients. Martin Cetron, director of the Division of Global Migration and Quarantine at the Centers for Disease Control and Prevention, discusses the emerging virus.

Fish Oil: Too Much of a Good Thing?

Jul 19, 2013

Fish oil may have some benefit for the heart. But a study in the Journal of the National Cancer Institute links higher blood levels of the omega-3 fatty acids in fish oil to a higher risk of prostate cancer. Study author Alan Kristal says the potential mechanism is unclear, but he warns that supplements can sometimes increase the risk of the very diseases they're meant to prevent.

Astronomers have detected a previously unseen moon orbiting Neptune, bringing the planet's moon count to 14. Mark Showalter, an astronomer at the SETI Institute, describes how he spotted the 12-mile moon while combing through old images taken by the Hubble Space Telescope.

Reporting in Science, researchers write of discovering four radio bursts from outer space. Physicist Duncan Lorimer, who detected the first such explosion in 2007, discusses what could be causing these radio signals, such as evaporating black holes, an idea proposed by Stephen Hawking in the 1970s.

A day at the shore can leave beachgoers with more than a sunburn — a gulp of seawater can expose swimmers to disease-causing microbes like norovirus, salmonella, and adenovirus. Marine scientist Rachel Noble and environmental medicine researcher Samuel Dorevitch discuss the risk, and what's being done to limit swimmers' exposure.

For years, electrical experts have been calling for a "smart grid" that could better sense and adapt to changing conditions, from electrical outages to shifts in power consumption. Massoud Amin, referred to by some as the "father of the smart grid," talks about how and why the country should improve its aging electrical infrastructure.

Can White Blood Cells Spread Cancer?

Jul 5, 2013

Transcript

IRA FLATOW, HOST:

This is SCIENCE FRIDAY. I'm Ira Flatow. White blood cells are part of our body's defense system. Their job is to attack invaders, and one of the first white blood cells sent out is the neutrophil. These neutrophils put out a trap to capture and destroy the invaders. But here's where it gets interesting, because in a new study, researchers say they have shown that these nets might actually activate and spread the cancer cells. It's the exact opposite of what you want. But there may be a way to counteract this problem.

Exactly a year ago this week, a video on YouTube went viral. It was called "Heat Buckles Highway, SUV Goes Airborne." A road in Wisconsin buckled so badly from the heat that it sent cars flying. Well, this year, the buckling continues. But if you're in certain parts of the country, you don't need me to tell you that. It's hot, and I'm not going to use that but-it's-a-dry-heat line, either.

This is SCIENCE FRIDAY. I'm Ira Flatow. Seems like every other week, a new study, complete with a colorful brain scan and a great headline, links a spot on the brain with the way we act. This is your brain on love; this is your brain on prayer; this is your brain on politics. But can a scan of your brain really tell you something about your beliefs and behaviors?
