• Crime Software: Still Awaiting a Verdict

  Scientific data not yet in on how much crime-reduction software predicts, and how much it motivates.

  Seattle last week became the latest city to install software that tries to predict where crime will strike, giving cops an edge. Indeed, crime reductions have been observed in cities where the tool—called Predpol—is installed and its recommendations followed. But with a dozen cities having joined the bandwagon, one fact is worth noting: no scientific paper has showed to what extent the software itself deserves credit, and whether the power of suggestion, and increased efforts on the officers’ part, might be playing a role.

  BMW’s approach to quelling range anxiety differs markedly from the tactics of other automakers.

  While they wait for cheaper batteries that can store more energy, carmakers are trying a range of strategies to compensate for the shortcomings of existing batteries. One of the latest, coming from BMW for the electric i3 slated to come out this year, is to offer customers loaner cars for long trips (see “BMW Shifts into Electric Gear”).

  The fortunes of the world’s largest social network depend on how much it can earn from mobile advertisements.

  Scarcely a year ago, Facebook was the poster child for Internet companies blindsided by the rapid shift of online activity from computers to smartphones and tablets. Just before its highly anticipated initial public offering last May, Facebook revealed that it wasn’t making “any significant revenue” from its mobile website or app—even though more than half its 900 million members used the service on mobile devices.

• Brain-Boosting Technique Might Help Some Functions While Hurting Others

  Electrically stimulating the brain may enhance memory, but impede with a person’s ability to react without thinking.

  We would surely all love a way to boost our brain power. But new research suggests that one promising experimental method could come with a cost. Using a noninvasive technique to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot. But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another part of the brain had the reverse effect, on both learning and automaticity.

  Surgical robots allow surgeons to perform a variety of less invasive operations because their miniaturized instruments can work through small incisions in the body and are more dexterous than traditional laparoscopic tools (see “The Slow Rise of the Robot Surgeon”).  The result is that patients leave the operating room with a smaller surgical wound with the promise of faster recovery and less scarring.

• Research Hints at Graphene’s Photovoltaic Potential

  Newly observed properties mean graphene could be a highly efficient converter of light to electric power.

  Researchers have demonstrated that graphene is highly efficient at generating electrons upon absorbing light, which suggests that the material could be used to make light sensors and perhaps even more efficient solar cells.

  Conventional materials that turn light into electricity, like silicon and gallium arsenide, generate a single electron for each photon absorbed. Since a photon contains more energy than one electron can carry, much of the energy contained in the incoming light is lost as heat. Now, new research reveals that when graphene absorbs a photon it generates multiple electrons capable of driving a current. This means that if graphene devices for converting light to electricity come to fruition, they could be more efficient than the devices commonly used today.

  Previous theoretical work had inspired hope that graphene had this property, says Frank Koppens, a group leader at the Institute of Photonic Sciences in Spain, who led the research. He says the new result, described this week in Nature Physics, represents the first experimental proof.

  To perform the experiment, the researchers used two ultrafast light pulses. The first sent a prescribed amount of energy into a single layer of graphene. The second served as a probe that counted the electrons the first one generated.

• Rats Communicate Through Brain Chips

  Researchers show that animals can collaborate via a brain-to-brain interface.

  Pairs of rats can communicate through brain chips and collaborate to perform a task, report researchers in today’s Scientific Reports. Brain activity recorded in one rat was translated into a pattern of electrical pulses that were then transmitted to another rat that had been trained to push a particular lever in response to one of two patterns of electrical stimulation in its brain. The rats also worked together, say the researchers. If the second rat chose the wrong lever, then the first rat would change its brain function and behavior in the next trial so that the receiving rodent was more likely to get it right, claim the scientists.

Technology for the elderly may not be the sexiest topic, and seniors in general may not be the coolest demographic, but technology companies should be doing more of this. There may or may not be a business case for laving R&D on seniors, but if nothing else, it’s the right thing to do, and could inspire a kind of generational trickle-down brand loyalty to the sons, daughters, and grandkids who would buy these products.

  Nabsys’s technology could provide the positional accuracy missing from current DNA sequencing methods.

  Nabsys, a DNA technology startup, showed off today its solid-state gene sequencing machine at the Advances in Genome Biology and Technology conference in Marco Island, Florida. The company says that later this year it will begin selling its machine, which will allow researchers to determine the structural organization of long stretches of DNA. This differs from most existing sequencing methods, which read DNA in short snippets that are later stitched together by software. The new system will, at first, complement existing methods, but it could eventually offer cheaper and faster sequencing than other approaches.

  
  
  
  
  
  

• F-22's Human Interface Kills Humans, Then Lands Them Safely

  User experience design eats its own tail in a high-tech military boondoggle.

  Think Windows 8 is a usability nightmare? Two pilots of the infamously expensive F-22 fighter jet recently went on 60 Minutes to describe how this “phenomenal, phenomenal machine” poisons its pilots’ air supply in the course of normal flight. But the plane is also smart enough to land itself with no help from its passed-out pilot. This is UX design by way of Brazil: the human interface is so bad that it actively tries to kill you the entire time you’re using it, and so good that it can deliver your comatose body back to safety with no help from you at all.
