Science proves people lie for selfish reasons
How honest are you, really? Would you be open to a brain treatment that might make you act a little more truthful? I'm asking because researchers from the ever-productive University of Zurich tried an experiment to see if they could influence behavior with "transcranial direct current stimulation (tDCS)," a noninvasive type of electrical pulse that apparently makes brain cells more active. The scientists targeted the right dorsolateral prefrontal cortex (involved with risky and moral decision making) with the tDCS to see how honest people would be when reporting dice rolls.
ICYMI: Ripples in Spacetime, brain jolts to learn and more

They spotted the gravitational waves made when two black holes collided.
New technology keeps drones from crashing and burning
Small drones could easily be blown off course by harsh winds or lose access to GPS while passing through somewhat closed-off locations. Since either scenario could spell disaster for delivery or service drones of the future, a research team from the University of Zurich has devised a system that autonomously sets them upright and finds them a good place to land. This technology requires drones to be equipped with a camera, an inertial measurement unit (IMU), a distance sensor and a tiny smartphone chip that processes all the data for them. In order for the system to work, the drone has to look for and identify landmarks through the camera, while it's still flying steadily with a working GPS.
Your smartphone is changing the way your fingers work
Your smartphone is changing more than just your habits -- it's changing the way your hands work, too. Swiss researchers have discovered that activity in the brain's cortex associated with index fingers and thumbs is enhanced directly in proportion to how often you use your phone's touchscreen. That area of your mind will light up if you message your friends all week, but it'll fade the longer you spend away from your device. People with basic cellphones don't see this, according to the scientists. This suggests that repetitive smartphone use is altering your sensory processing, and that your brain is perceiving your digits in a different way. Whether or not that's a good thing is still up in the air, but it shows that you don't have to be in a profession driven by hand dexterity (such as music) to see a shift in how your brain and fingers work together.

DNA smeared on a rocket survives re-entry and tells of life's origins
Well, would you look at that: scientists have discovered that DNA can make it through the hellish ordeal of atmospheric re-entry after all. German and Swiss researchers dotted a rocket's grooves and screw heads with fragments of genetic blueprints to see how they'd fare in situations that could've led to the appearance of life on Earth. Scientific American notes that the 13-minute rocket trip might not perfectly represent how DNA might actually travel from one celestial body to the next (that'd be by meteor), but there is purpose here. What the experiment suggests is that even if the meteor's been scorched, that the material can survive at higher temperatures than previously expected, and as such this paints a better picture of just how resilient DNA is. What's next? Pushing the limits further and seeing exactly what it takes to kill the double helix -- we're pretty sure at least one rock band is itching to find out.

Nanotech polyester fabric never gets wet, brings back the leisure suit in a big way
Researchers at the University of Zurich have combined the stylish, debonair appeal of polyester with the cutting edge science of nanotechnology to create a material that just cannot get wet. When coated with millions of 40nm-wide silicone nanofilaments, the hydrophobic polyester is protected by a layer of air that prevents water from making contact with the fibers beneath. Since water never makes it to the material, it can be submerged for two months and still remain dry to the touch. According to scientists, nano-polyester could be used to make swimwear with low water resistance and self-cleaning clothes. And who knows? It just might herald the return of wide lapels, bell bottoms or even (and we admit, this one's a long shot) Tony Orlando & Dawn. Our fingers are crossed!
