More reliable and power efficient ferroelectric memories
A team documented what is called the nanoscale switching of a ferroelectric memory bit. Ferroelectric materials have the potential to replace some of the current memory technologies, and may offer greater storage and require less power to retain computer data. The researchers' findings could help bring about a significant change in computer memory technology and reduce its electrical power demands.

Paper uncovers power of Foldit gamersí strategies
Researchers studying the nature of crowds playing Foldit called some strategies "shocking" in how well they mimicked some of the methods already used by protein scientists. Gamers made headlines in September for unraveling the structure of a protein central to research on AIDS. Today University of Washington researchers reveal the creative power of Foldit players' strategies and compare them to the best-known scientist-developed methods.

Solving Einsteinís theory
Solving Einsteinís theory
A team of University researchers will get their hands on some of Europe's fastest supercomputers in a bid to crack Einstein's theory of relativity and help describe what happens when two black holes collide. Experts in gravitational waves from the School of Physics and Astronomy have secured almost 16.7 million hours worth of supercomputer time to simulate and map the most violent events in the universe since the big bang - namely, collisions of black holes.

Could social media be used to detect disease outbreaks?
Could social media be used to detect disease outbreaks?
New research has looked at whether social media could be used to track an event or phenomenon, such as flu outbreaks and rainfall rates. The study by academics at the University of Bristol's Intelligent Systems Laboratory is published online in ACM Transactions on Intelligent Systems and Technology .

Computer-based tool to improve diagnosis and prognosis for cancer patients
PA 336/11 A computer-based tool could help GPs to speed up the diagnosis and treatment of patients suffering from two of the most common forms of cancer, potentially saving thousands of lives every year. Researchers at The University of Nottingham and ClinRisk Ltd have shown that the algorithm is successful in identifying those suffering with gastro-oesophageal cancer and lung cancer at an earlier stage by 'red-flagging' potentially worrying combinations of symptoms and risk factors.

Sexting driven by peer pressure
Both young men and women experience peer pressure to share sexual images via the new phenomenon of 'sexting', preliminary findings from a University of Melbourne study has found. 'Sexting' is the practice of sending and receiving sexual images on a mobile phone. The study is one of the first academic investigations into 'sexting' from a young person's perspective in Australia.

The apple doesnít fall far from the tree - or does it?
Research has shown that contrary to what was thought from previous studies, spin-outs don't systematically set up shop near their parent companies. To stay or to leave, what's the best strategy? "I was really surprised, when doing this research, to find that 50% of spin-outs don't necessarily establish themselves near the parent company," observes Christopher Tucci from EPFL.

Input/output: The Economics of Database Searching
Searching the internet might seem simple, but applying a little bit of economic theory to information retrieval can shed some light on the best search strategies to adopt, according to researchers. Leif Azzopardi from the School of Computing Science at the University of Glasgow took production theory from microeconomics and applied it to the process of searching the internet, or any other database system.

Dramatic simplification paves the way for building a quantum computer
Dramatic simplification paves the way for building a quantum computer
An international research group has demonstrated a new technique that dramatically simplifies quantum circuits, bringing quantum computers closer to reality. Xiao-Qi Zhou and colleagues at the University of Bristol's Centre for Quantum Photonics and the University of Queensland, Australia, have shown that controlled operations ' ones that are implemented on the condition that a 'control bit' is in the state 1 - can be dramatically simplified compared to the standard approach.
