There was an opening ceremony on Feb. 5 for the Yale Institute for Network Science (YINS), dedicated to exploring fundamental properties of networks as they appear throughout the biological, physical, and social sciences.

The interdisciplinary institute will be led by co-directors Nicholas Christakis, the Sol Goldman Family Professor of Social and Natural Science, and Daniel Spielman, the Henry Ford II Professor of Computer Science and Mathematics.

Christakis and Spielman recently met with YaleNews to discuss the nature of networks and the institute’s mission. The following is an edited version of the conversation. (more…)

The Barriers of E-learning and How to Survive It

Students can experience convenience and benefits but at the same time, barriers of E-learning. These barriers hinder the learning process that is why it is important to evaluate the kind of barrier and know how to survive it.

Technology Issues

E-learning doesn’t require students to be very good with computers, software, and Internet. It only requires little technical skill. But there are some people who really find it hard to deal with technology issues. If they won’t do anything to resolve it, they will only feel frustrated that will only lead to not continuing the learning process. (more…)

UCLA physicists’ technique for cooling molecules may be a stepping stone to quantum computing

The next generation of computers promises far greater power and faster processing speeds than today’s silicon-based based machines. These “quantum computers” — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from a collection of super-cooled molecules.

But chilling molecules to a fraction of a degree above absolute zero, the temperature at which they can be manipulated to store and transmit data, has proven to be a difficult challenge for scientists. (more…)

Social Network Use Reflects East-West Disparity

The stark contrast between America’s “me-first” culture and the “collective-good” mentality in China is reflected in the two countries’ use of social networking sites, according to a new study led by a Michigan State University scholar.

U.S. citizens spend more time on the networking sites, consider them to be more important and have more “friends” on the sites, the research found. The most popular social networking site in the United States is Facebook; in China, two of the most popular sites are RenRen and Qzone. (more…)

UCLA Engineers Develop New Energy-Efficient Computer Memory Using Magnetic Materials

MeRAM is up to 1,000 times more energy-efficient than current technologies

By using electric voltage instead of a flowing electric current, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM.

The UCLA team’s improved memory, which they call MeRAM for magnetoelectric random access memory, has great potential to be used in future memory chips for almost all electronic applications, including smart-phones, tablets, computers and microprocessors, as well as for data storage, like the solid-state disks used in computers and large data centers.

*Organizations around the world are addressing cyberbullying — and digital safety overall — by empowering youth and providing educators with resources to help them navigate the digital world. Includes tips for preventing cyberbullying.*

Redmond, Wash. — Aug. 25, 2011 — For all the benefits that smartphones, computers and the Web have to offer — especially for young people who have embraced digital technology and use it every day — there will always be those who misuse the technology to harass others, including their peers.

Known as “cyberbullying,” this problem can occur at any time of the day or night, due to the always-on nature of the devices and technologies used to create these hurtful interactions. So, for some young people, home offers no respite from being victimized. In fact, cyberbullying has beome common enough that the term was recently added to the Concise Oxford English Dictionary.

REDMOND, Wash. – Feb. 24, 2011 – Microsoft provided a glimpse into computing’s future at the Microsoft Home this week, showing demos of 3D and virtual worlds, vision systems that create new models for interacting with computers, and research that explores potential scenarios for Kinect beyond gaming.

Mundie and Don Mattrick, president of Microsoft’s Interactive Entertainment Business, also announced plans to make a Kinect for Windows software development kit (SDK) available this spring. The non-commercial SDK will be geared to academics and enthusiasts. (more…)

Revolutionary Computing: $100 Million DARPA Program to Develop Next Generation of High Performance Computers

Imagine that one of the world’s most powerful high performance computers could be packed into a single rack just 24 inches wide and powered by a fraction of the electricity consumed by comparable current machines. That would allow an unprecedented amount of computing power to be installed on aircraft, carried onto the battlefield for commanders – and made available to researchers everywhere.

Putting this computing power into a small and energy-efficient package, and making it reliable and easier to program, are among the goals of the new DARPA Ubiquitous High Performance Computing (UHPC) initiative. Georgia Tech researchers from three different units are supporting key components of this $100 million challenge, which will require development of revolutionary approaches not bound by existing computing paradigms.
