Researchers at Rice University are designing transparent, two-terminal, 3D computer memories on flexible sheets that show promise for electronics and sophisticated heads-up displays. The technique is based on the switching properties of silicon oxide.
One hundred years after the birth of mathematician and computer scientist Alan Turing, whose “Turing test” stands as one of the foundational definitions of what constitutes true machine intelligence, a virtual “gamer” created by computer scientists at The University of Texas at Austin has won the annual BotPrize by convincing a panel of judges that their software-based robot was more human-like than half the humans it competed against.
No longer limited to narrow focus groups, painstaking in-person surveys, or artificially controlled studies, researchers today have a far easier time compiling and manipulating large data sets. At the same time, however, sharing such data can be fraught with risks. Researchers with the “Privacy Tools for Sharing Research Data” project at Harvard University aim to keep the flexibility and convenience of sharing large amounts of data while more fully protecting individual privacy.
This week, an open innovation challenge called Mozilla Ignite announced eight winning ideas for innovative applications that offer a glimpse of what the Internet's future might look like, and what the lives of Americans may look like as well. The challenge called for stellar application, or "app," ideas from anywhere in the world that would advance national priorities such as health care, public safety, clean energy, and transportation.
As data centers continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough have a suggestion: turn the air conditioning down. Their latest research suggests that turning up the temperature could save energy with little or no increased risk of equipment failure.
A Purdue University physicist, Leonid Rokhinson, has observed evidence of long-sought Majorana fermions, special particles that could unleash the potential of fault-tolerant quantum computing. Rokhinson led a team that is the first to successfully demonstrate the fractional a.c. Josephson effect, which is a signature of the particles.
The human body is proficient at making collagen. And human laboratories are getting better at it all the time.
