I have good news and bad news. The good news is that Asteroid 2012 DA14 is not going to hit Earth. The bad news is, even if it were going to hit Earth, it wouldn't happen until February 15th so you will still have to buy a Valentine's Day gift.

Asteroid 2012 DA14 was discovered last year, on February 22nd by astronomers at La Sagra Sky Survey observatory near Granada, Spain. Because it is small in size it was only noticed after it had flown past us, but astronomers knew then it would be back, this time much closer.

How close? 24,000 KM close.  As in the distance of some satellites. That means you will be able to see it with binoculars.

It's the weekend, which means it is time for scientists, science journalists, book authors and intellectually curious readers to think about microbiology.  And that means beer. Beer is actually safer to drink than water. You didn't know that?  Let's talk some biology.

The master ingredient in beer is yeast. That's a microbe! So if you do experiments with beer this weekend, you are advancing the world of science.  If you make beer, you are a microbiologist.  If you drink beer, you are a microbiologist. Microbiologists understand beer and bacteria and stuff, which is why they drink beer more than water.

President Obama recently got some ridicule for hastily claiming he loved skeet shooting and therefore was not against sportsmen when he wanted to tell Americans they couldn't be trusted to decide how many bullets to buy for their guns.

That he was simultaneously offering bombs and fighter jets to terrorists in Egypt while he didn't trust his own citizens with small arms ammunition was not lost on his critics.

What happens when thousands of scientists do decades of research and taxpayers spend spend $15 billion on a scientifically validated site for nuclear waste storage but those science conclusions conflict with the anti-science beliefs of a president and his key ally in the Senate?
