Playing a First-Person Shooter Using Real Guns 225

Blake writes "A group called Waterloo Labs rigged up a few accelerometers to a large wall and projected a first-person shooter onto it. Using some math, they can triangulate the position of impacts on the wall, so naturally they found someone with a gun and bought a large case of ammunition. Even cooler, this group usually posts a 'how we did it' video a few weeks after a project's debut, including source code."

Nanotech Paint To Kill Bacteria 208

ColGraff points out reporting at Science News about the possibility of killing bacteria with paint. Scientists in the UK have found that high concentrations of titanium oxide nanoparticles in paint can kill bacteria by creating hydroxyl radicals when exposed to ordinary fluorescent light. Titanium dioxide is present in most white paint at concentrations of 30% or so, but not always at nanoparticle scale. The researchers found that an 80% concentration of TiO2 nanoparticles worked well to kill E. Coli bacteria. There is hope that the technique could be used against "superbugs," which are resistant to multiple antibiotics. A researcher not associated with the UK team pointed out the problem with developing products based on this idea: "[A]nything that survives and sticks around grows greater resistance... ultimately [antibiotic paint] will be its own worst enemy and the bacteria could grow to be even stronger."

Where To Draw the Line With Embryo Selection? 727

Tjeerd writes "There is currently a discussion going on in the Netherlands about embryo selection. The process means that when using in vitro fertilization, you can check what kind of genetic defects will definitely become activated during life. When embryos with those defects are identified, they can be avoided or destroyed. The next step the government is considering is to make it possible to select against genetic defects which might become active in life, such as breast and colon cancer. Of course, this is a very difficult discussion; where do you start, and where do you end? People are worrying that there is no real limit, and that you could potentially check for every genetic defect. I think if you're in a situation where you or your family have genetic defects, you surely want to check whether your children would have them too. What does the Slashdot community think about this?"

Doctors To Control Robot Surgeon With Their Eyes 99

trogador writes "Researchers from Imperial College London are improving the Da Vinci surgical robot by installing an eye-tracker, which allows surgeons to control the robot's knife simply by looking at the patient's tissues on a screen. Tracking the eyes can generate a 3D map, which in turn can make moving organs — like a beating heart — appear to stand still for easier operation. Other features include 'see-through' tissues on the surgeon's screen (so tumors can be seen underneath tissues) and 'no-cut' zones, places where the robot won't allow the surgeon to cut by mistake. Says ICL Professor Guang Zhong Yang, 'We want to empower the robot and make it more autonomous.'"

Nanotechnology-Powered Wiper-Less Windshield 178

fab writes "Italian car designer Leonardo Fioravanti (who worked for Pininfarina for a number of years) has developed a car prototype without windshield wipers. This amazing technological feat is made possible thanks to the use of 4 layers of glass modified using nanotechnology. The first layer filters the sun and repels the water. The second layer, using 'nano-dust' is able to push dirt to the side. The third layer acts as a sensor that activates the second layer when it detects dirt, while the fourth layer is a conductor of electricity to power this complex mechanism. I haven't been able to find an English article, but there is always a google powered translation of the Italian article."
