New game controller gets emotional

When it comes to entertainment, there are few other media that feature the level of user interaction of video games. Now, researchers at Stanford University are looking to make games more interactive. They've developed a prototype controller that monitors the player's physiological responses, then changes the gameplay to make it more engaging based on the player's feelings. Read More

Stanford scientists find a new way to turn graphite into diamond

Pressure makes diamonds, but according to recent findings, there may also be a much quicker, hassle-free way. A team of researchers at Stanford University has stumbled upon a new way of turning graphite (the material used for pencil leads) into a diamond-like carbon structure simply by applying hydrogen over a platinum substrate, without the need to apply external pressure of any kind. The discovery could lead to easier and more flexible manufacturing of diamonds used in cutting tools and other industrial devices. Read More

Folding paper microscope could reduce deaths from malaria

According to the World Health Organization, there were approximately 207 million cases of malaria worldwide in 2012, 627,000 of which proved fatal. Unfortunately, the disease most often occurs in developing nations, where diagnostic equipment may not be available. This means that doctors can't determine the particular strain of malaria from which a patient is suffering, and thus don't know which medication will work best. Manu Prakash, an assistant professor of bioengineering at the Stanford School of Medicine, hopes to change that ... using his disposable folding paper microscope. Read More

EyeGo adapters let you perform eye exams with a smartphone

When it comes to thoroughly assessing the condition of someone's eyes, it's usually necessary to utilize large, expensive contraptions such as those found in an ophthalmologist's office. While that's OK in some situations, physicians in rural areas or developing nations might not have access to such technology. Additionally, emergency room personnel typically need information on-the-spot, ASAP. That's why two scientists from Stanford University have created the EyeGo system, which allows smartphones to do the job. Read More

Gamers outshine computers in crowdsourced RNA modeling

Results from the crowdsourced game and experiment, EteRNA, which combines RNA folding puzzles with laboratory synthesis, show that human gamers are able to develop better models of RNA folding than previous computer algorithms. Design rules formulated by the online community have even been used to construct a new algorithm, EteRNABot, and in some cases represent completely new understandings about RNA folding that have yet to be explained mechanically.

Tin-based stanene could conduct electricity with 100 percent efficiency

A team of theoretical physicists from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University is predicting that stanene, a single layer of tin atoms laid out in a two-dimensional structure, could conduct electricity with one hundred percent efficiency at room temperature. If the findings are confirmed they could pave the way for building computer chips that are faster, consume less power, and won't heat up nearly as much. Read More

Self-healing electrode coating could lead to longer-lasting batteries

In their continuing efforts to increase the energy density of lithium-ion batteries, scientists have began looking at alternative materials for those batteries' electrodes – materials such as silicon. The problem is, electrodes swell and shrink as they absorb and release lithium ions, causing them to break down over time. This is particularly true of silicon, which is brittle by nature. Now, however, scientists have developed a conductive elastic polymer coating for those electrodes, that heals its own cracks after each use. Read More
