One-atom-thick germanium sheets could replace silicon in semiconductors
It consists of one-atom-thick sheets and it could revolutionize electronics ... but it’s not graphene. Chemists at Ohio State University, instead of creating graphene from carbon atoms, have used sheets of germanium atoms to create a substance known as germanane. Because of its numerous advantages over silicon, it could become the material of choice for semiconductors. Read More
Last year, a group of Harvard University scientists led by Dr. Joanna Aizenberg announced the development of a highly-hydrophobic (water-repellant) material known as SLIPS, or Slippery Liquid Porous Surfaces. The material is remarkable, in that it repels virtually any liquid. Now, Aizenberg and colleagues have created a new material inspired by human tears, the repellency of which can be fine-tuned for different applications. Read More
People recovering from strokes can often find rehabilitation very frustrating. They try to move their hand in a certain way, for instance, but it just won’t do it – why not? That’s where a new system known as the Synergistic Physio-Neuro Platform (SynPhNe) comes into the picture. It guides patients through exercises, monitors their performance, and lets them know why they’re unable to perform certain tasks. They can then use that knowledge to self-correct their actions, instead of just getting exasperated. Read More
When you think about portable biometric identification devices (you do think about them, right?), you likely picture relatively bulky contraptions. This week, however, California tech company AOptix announced its new Stratus biometrics system, that’s based around the user’s existing iPhone 4 or 4S. Read More
Well, that didn’t take long. Just this January, DJI Innovations released its GPS-enabled Phantom quadcopter. Now, at this week’s National Association of Broadcasters show in Las Vegas, the company has unveiled a self-stabilizing camera mount that can be added to existing Phantoms, plus an upgraded Phantom that includes its own HD video camera. Additionally, DJI’s new iOS app allows users to view onboard video output in real time on their iPhone, iPad or iPod touch via Wi-Fi. Read More
Researchers at Indiana’s University of Notre Dame recently placed an anesthetized lab rat in a CT scanner, created a digital 3D model of its skeleton from the scan data, and then sent that model to a commercial MakerBot 3D printer. A highly-accurate plastic replica of the skeleton was the end result. Read More
Deep Brain Stimulation, in which a pacemaker-like device activates select regions of the brain via implanted electrodes, has been used to help people suffering from a variety of neurological problems. Just in the past few years, studies have explored its use for treating anorexia, Alzheimer’s, and memory disorders. Now, perhaps not surprisingly, scientists from Germany’s Bonn University Hospital have found that it also appears to do wonders for acute depression. Read More
Falling snow can play havoc with radar systems, so the more that we know about the manner in which snow falls, the better that those systems can be equipped to compensate for it. That’s why for the past three years, researchers from the University of Utah have been developing a device known as the Multi-Angle Snowflake Camera – or MASC. Using three cameras and two motion sensors, it captures 3D photos of snowflakes in free-fall. Read More
Long before the Leatherman ever existed, the Swiss Army Knife became one of the first commercially-produced multi-tools. Now, no doubt aware of the increasing popularity of cycling-specific multi-tools, Victorinox has introduced its Swiss Army Bike Tool. Read More
The spleen’s job is to filter our blood. When people are critically ill or have received traumatic injuries, however, the spleen alone is sometimes not able to remove enough of the pathogens on its own – potentially-fatal sepsis is the result. In order to help avert such an outcome in those situations, scientists from the Wyss Institute for Biologically Inspired Engineering at Harvard University are developing a device known as the spleen-on-a-chip.
