FDA May Approve Drugs to Counteract Nuclear Radiation

With the current state of things, it's nearly impossible to turn on the news without hearing some passing reference to chemical or nuclear warfare. And while we have at least some countermeasures ready to minimize damages from the former, it's the nuclear part that leaves us biologically defenseless.

AT&T gets official with LG Optimus G Pro, available May 10th for $200 on-contract

We've already seen this one leaked and detailed -- and reviewed the non-AT&T variant ourselves -- but the carrier's now finally gotten official with its latest high-end smartphone: the LG Optimus G Pro. If this is the first you're seeing of it, though, you're looking at a phone with a 5.5-inch, 1920 x 1080 IPS display (which translates to 400ppi), along with a 13-megapixel camera (2.1 megapixel front-facing), LTE connectivity, a 3,140 mAh battery, 32GB of storage and Android 4.1.2 with some of LG's customizations. As we noted in our review, that puts it up squarely against the Samsung Galaxy Note II, although LG's decided to forego the stylus here. Look for this one to be available (exclusively on AT&T, incidentally) starting May 10th for $199.99 on the usual two-year contract.

Chael Sonnen not retiring, eyes Wanderlei Silva

Chael Sonnen's loss to Jon Jones at UFC 159 put his career in question. At 36 years old, and with title losses in two different divisions, would Sonnen consider retiring? He answered that question on Fuel's "UFC Tonight," and that answer is no.

"I have a lot of goals I want to achieve still, and retirement won't help me get that done," Sonnen said.

He said the weight class is up for debate, though he liked the switch to light heavyweight after years as a middleweight. He would also be happy to fight at a catchweight, like Rich Franklin did for a few fights when moving up in weight. But there's no question about who he wants to fight.

"I'm not going anywhere until me and Wanderlei [Silva] straighten this thing out once and for all,"

Like Sonnen, Silva has moved between middleweight, light heavyweight and catchweights somewhere between. He is also 36, but the sensible match-up isn't why Sonnen is interested in this bout. Sonnen has a problem with this video from 2010:

Here is how Sonnen viewed this video.

"Wanderlei pulled a really dirtbag move on me one time. We're in a van, he mutters something at me, I can't understand what he's saying. He then puts it on YouTube with subtitles because he knows I can't understand him. He puts in these subtitles and I don't know if it's what he's said or not. Essentially, he tells me off, and it looks as though I'm conceding to him. That doesn't fly. If he calls you out, whether it's in a van or not, if you're a fighter, you must respond. I'm ready to respond."

Silva responded by tweeting this:

And then sharing the above video and saying, "Real men talk face to face."

Is this a fight you want to see, Cagereaders? Speak up on Facebook or Twitter.

New evidence on how fluoride fights tooth decay

New evidence on how fluoride fights tooth decay [ Back to EurekAlert! ] Public release date: 1-May-2013

In an advance toward solving a 50-year-old mystery, scientists are reporting new evidence on how the fluoride in drinking water, toothpastes, mouth rinses and other oral-care products prevents tooth decay. Their report appears in the ACS journal Langumir.

Karin Jacobs and colleagues explain that despite a half-century of scientific research, controversy still exists over exactly how fluoride compounds reduce the risk of tooth decay. That research established long ago that fluoride helps to harden the enamel coating that protects teeth from the acid produced by decay-causing bacteria. Newer studies already found that fluoride penetrates into and hardens a much thinner layer of enamel than previously believed, lending credence to other theories about how fluoride works.

The report describes new evidence that fluoride also works by impacting the adhesion force of bacteria that stick to the teeth and produce the acid that causes cavities. The experiments performed on artificial teeth (hydroxyapatite pellets) to enable high-precision analysis techniques revealed that fluoride reduces the ability of decay-causing bacteria to stick, so that also on teeth, it is easier to wash away the bacteria by saliva, brushing and other activity.
