Why E. coli move faster in syrup-like fluids than in water
Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn't understand why. New findings could inform disease models and treatments, or even help design microscopic swimming robots.

Great Barrier Reef protecting against landslides, tsunamis
The world-famous Australian reef is providing an effective barrier against landslide-induced tsunamis, new research shows. An underwater landslide has been found to have occurred some 20,000 years ago, causing a tsunami. Similar submarine landslides could occur without our knowledge but the Great Barrier Reef can absorb some of that potential wave energy.

The LHC collides ions at new record energy
After the successful restart of the Large Hadron Collider and its first months of data taking with proton collisions at a new energy frontier, the LHC is moving to a new phase, with the first lead-ion collisions of season 2 at an energy about twice as high as that of any previous collider experiment.

Comet fragments best explanation of mysterious dimming star
Astronomers have responded to the buzz about a mysterious dimming star by studying data from NASA's Spitzer Space Telescope. They conclude the dimming was probably caused by a family of comets passing in front of the star.

New 'party pill' test could help authorities keep up with trends in drug (ab)use
A new test for club drugs like ketamine can detect low levels of drugs in urine and plasma, making it faster, easier and cheaper to identify them. The authors of the study say it could give authorities the boost they need to keep up with trends drug (ab)use. A new class of drugs known as “new psychoactive substances” has recently hit the clubs. Sold online or in smart shops as “legal highs,” these drugs pose a problem for authorities because they’re difficult to analyze and it’s tricky to keep up with the speed at which trafficking shifts to new products. There is currently no standard screening test for these drugs. One widely used club drug is ketamine – traditionally an animal tranquilizer – which causes users to hallucinate.

Enhanced detection of Parkinson's
New research by biologists could lead to improved methods of detection for early-onset Parkinson’s Disease. By mapping the visual responses of fruit flies with different Parkinson's genes, the scientists built a substantial data bank of results. Using this they were able to classify unknown flies as having a Parkinson's related mutation with 85 per cent accuracy.

Why bartenders have to ignore some signals
A robotic bartender has to do something unusual for a machine: It has to learn to ignore some data and focus on social signals. Researchers recently investigated how a robotic bartender can understand human communication and serve drinks socially appropriately.
