Bacteria love hanging out between your teeth—food gets caught there, and brushing can’t reach all the germs. If the bugs settle in and form a cavity, your dentist must drill through your tooth just to get at it. But now dentists can trade their drills for a simple treatment that stops early-stage cavities.

An 11-year-old boy taps furiously on a laptop, blasting enemies as he weaves through a maze. They wipe him out before he can reach the end—game over. Frustrated, he opens the game’s programming window, adjusts the gravity setting, and this time bounds over the baddies. Victory!

The ACLU is one step closer to getting patents on human genes banned after a federal court today ruled that its lawsuit can continue. The defendants (The US Patent and Trademark Office and the owners of the BRCA breast cancer gene patent) had asked the court to dismiss the case.

About 20 percent of the human genome is currently patented, including genes associated with many diseases such as breast cancer and Alzheimer's. The patents mean that outside researchers need permission to study the genes and that tests can be astronomically expensive. (The test for BRCA is about $3,000.)

Today, a company called DeepDyve launched the largest online rental service for scientific papers, which allows users to rent any article for just 99 cents. Journal articles currently trend toward the obscene ($30 or more), unless you're the lucky dude with a password for a university library. DeepDyve saw an opening in the market and made deals with major scientific publishers to stock 30 million (and growing) articles of tech, med, and scientific interest.

DeepDyve is part of a greater trend of getting scientific info back to the hardworking taxpayers who funded it.

Lab mice, perk up your fuzzy little ears. You are not the only species that struggles through mazes in the name of science. Here, it's an eight-year-old boy who can't see too well. But don't feel bad, in the second video he aces the test when he's allowed to use his eye that's been treated with gene therapy. This procedure is one of the few successful applications of gene therapy, a technique that people once thought would cure nearly all ills, but problems getting the genes into the body's cells has plagued the field every step of the way.

For the first time, researchers have made a clinical diagnosis by sequencing the entire protein-coding parts of a person's genome.

"We have shown that one can use whole genome sequencing to make clinically meaningful diagnoses- it is technically feasible . . . and can provide new clinical insight that directs treatment," Richard Lifton, a geneticist at Yale who spearheaded the research, told Popsci.com.

Protein-coding DNA only makes up about one percent of the human genome, but is responsible for about a large portion of diseases with a genetic component.

Your grandma might think that the Internet is rotting your brain, but it's possible if she did a little face-time with Google that she could stay sharper in the noggin herself. In a new study, Internet novices who were instructed to search the web showed increased activity in areas of the brain associated with making decisions and memory in just two weeks, according to a poster presented today at the annual Society for Neuroscience conference.

A new coating turns insects' sticky climbing feet into a slippery mess, and could be the future of pest repellent, according to a new research paper. You hear that, bugs? If you can't crawl up my kitchen counter from the floor, you can't go waving your disgusting antennae all over my pizza, you insects-who-shall-not-be-named of apartment horror.

No matter how intelligent a robot might be, it’s nice knowing you can pull its plug to halt the anti-human insurrection. Whoops, not anymore. A new cohort of ’bots that make energy by gobbling organic matter could be the beginning of truly autonomous machines.

I can't seem to manage to keep my iPod in my bag for a day without creating an awful tangle of headphones, but my body's cells can work with two meters of stringy DNA into a tiny nucleus without making a knot. The secret is a structure called a fractal globule, according to a research paper to be published tomorrow in the journal Science.
