No more killing the good bacteria along with the bad. An antibiotic "smart bomb" can identify specific strains of bacteria and sever their DNA, eliminating the infection and reducing multi-drug resistant bacteria.

The new approach works by taking advantage of a part of an immune system present in many bacteria called the CRISPR-Cas system. The CRISPR-Cas system protects bacteria from invaders such as viruses by creating small strands of RNA called CRISPR RNAs, which match DNA sequences specific to a given invader. When those CRISPR RNAs find a match, they unleash Cas proteins that cut the DNA.

Marijuana use has been involved in a sharp increase in fatal motor vehicle crashes, with rates nearly tripling since 1999. 

The prevalence of non-alcohol drugs detected in fatally injured drivers in the U.S. has been steadily rising and tripled from 1999 to 2010. Marijuana is the most commonly detected non-alcohol drug involved. 

North American bats are facing a tough new millennium. 600,000 per year are already killed due to government subsidies of wind energy and so far 7 million have died due to White Nose Syndrome.

While we are likely stuck with wind energy for the foreseeable future, there is hope for White Nose Syndrome. Scientists have discovered that the deadly WNS fungus can survive in caves with or without the presence of bats.

If you are stressed about giving a public speech or a presentation to your boss, it helps to talk about it - if the person you are talking to is also stressed out.

People benefit by spending time and conversing with someone whose emotional response is in line with theirs. Such an alignment may be helpful in the workplace.

What would make snakes scarier?

For spiders, the answer is easy. If you see one big enough to be feasting on Orc flesh in the caves under Mt. Doom, run, but snakes are tougher to make scary because they are slow.

Not all of them. Snakes may not look aerodynamic but some snakes can fly - literally. They slither in air, creating an S shape as they glide as much as 90 feet.

But how do they generate the lift to stay airborne? Jake Socha has spent much of his career figuring out flying snakes and says  "They look like they are swimming. They turn their whole body into one aerodynamic surface."

The Annals of the American Thoracic Society has released a comprehensive supplement on the 56th annual Thomas L. Petty Aspen Lung Conference entitled "The Lung Microbiome: A New Frontier in Pulmonary Medicine."

More than 170 microbiologists, basic respiratory scientists, and pulmonary clinicians traveled from nine countries to convene at the three-day conference, which took place in June 2013 in Aspen, CO. Research from 12 state-of-the-art speakers, 24 oral research presentations, and 20 posters from pioneers in the emerging field are included in the supplement, as well as an introduction from conference chairs Richard J. Martin, MD, Sonia Flores, PhD, and Monica Kraft, MD, and a conference summary from James Kiley, PhD.
