CRISPR-Cas9 gene editing: Check 3 times, cut once
CRISPR-Cas9 is a powerful tool to edit genomes, but off-target edits are a concern. UC Berkeley studies detail three checks the Cas9 protein makes to ensure it binds the right DNA and that the sequence matches the RNA primer sufficiently to warrant cutting. At most off-target sites, Cas9 binds for milliseconds. Once it sticks for about a minute, two distant regions of the protein come together like the blades of a scissors to trigger cutting.

Human handouts could be spreading disease from birds to people
People feeding white ibises at public parks are turning the normally independent birds into beggars, and now researchers at the University of Georgia say it might also be helping spread disease. They recently launched a study to find out how being fed by humans is changing the health, ecology and behavior of white ibises in south Florida, where construction and land development is drying up their wetland habitats.

Zooplankton: Not-so-passive motion in turbulence
Imagine a species that is only one millimetre long and has only a limited swimming ability. Yet, its mobility is sufficient for moving, feeding and reproducing in freshwater and seawater. That's exactly what a type of zooplankton of the crustaceans family -- namely the calanoid copepods -- does. In a study published in EPJ E, physicists shed new light on how these zooplankton steer large-scale collective motion under strong turbulence.

New exoplanet in our neighborhood
Scientists have discovered a new exoplanet that, in the language of 'Star Wars,' would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of residing in a galaxy far, far away, this new world is, galactically speaking, practically next door.

Researchers develop antibiotic alternative for wound infections
Washington State University researchers for the first time have discovered how electrical stimulation works for the treatment of bacterial infections, paving the way for a viable alternative to medicinal antibiotics. The researchers passed an electric current over a film of bacteria and in 24 hours killed almost all of a multi-drug resistant bacterium that is often present in difficult-to-treat infections. The remaining bacterial population was 1/10,000th of its original size.

Geophysics could slow Antarctic ice retreat
The anticipated melting of the massive West Antarctic Ice Sheet could be slowed by two big factors that are largely overlooked in current computer models, according to a new study. The findings suggest that the impact on global sea levels from the retreating ice sheet could be less drastic -- or at least more gradual -- than recent computer simulations have indicated.

Markets for science
A recent estimate put the costs associated with irreproducible preclinical research at $28 billion a year in the United States. No mechanisms exist to quickly identify findings that are unlikely to be replicated. New research used prediction markets -- investment platforms that reward traders for correctly predicting future events -- to estimate the reproducibility of more than 40 experiments published in prominent psychology journals. The researchers found that prediction markets correctly predicted replicability in 71 percent of the cases studied.

Implantable wireless devices trigger -- and may block -- pain signals
Building on wireless technology that has the potential to interfere with pain, scientists have developed flexible, implantable devices that can activate -- and, in theory, block -- pain signals in the body and spinal cord before those signals reach the brain. The researchers, at Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign, said the implants one day may be used in different parts of the body to fight pain that doesn't respond to other therapies.
