Google recently announced that it will help fund groundbreaking research by computer scientists and economists at Tel Aviv University.  The Blavatnik School of Computer Science is attempting to help computers make better decisions using a term they dubbed "regret." Head of the program Professor Yishay Mansour began this project earlier this year at the International Conference on Learning Theory in Haifa, Israel.  He and the other researchers are working on algorithms that would allow computers to learn from their past failures in an effort to make better predictions.  This is referred to as "minimizing virtual regret" by Mansour. "If the servers and routing systems of the Internet could see and evaluate all the relevant variables in advance, they could more efficiently prioritize server resource requests, load documents and route visitors to an Internet site, for instance," says Mansour.

University of Minnesota researchers are a key step closer to making renewable petroleum fuels using bacteria, sunlight and dioxide, a goal funded by a $2.2 million United States Department of Energy grant.

Scientists in the UK and US, including researchers at Arizona State University, have been awarded funding to improve the photosynthetic process as a means of producing renewable fuel.

Whether in the present so-called 'age of austerity' or more generous times, arguing for funds for space exploration can sometimes be hard and constrained budgets mean that some excellent scientific proposals never see the light of day. On Tuesday 19 April, in his presentation at the National Astronomy Meeting in Llandudno, Wales, Leicester University astronomer Professor Martin Barstow argued that a solution could be found in the form of low-cost space missions with a price tag of £10-20m.

The sign was a digital billboard, a new breed of outdoor advertising that is growing in both the region and the nation. The problem for Young, a Philadelphia architect, is that they're energy guzzlers, compared with other signage. In a recent report, he found that the largest of them can use 30 times what a typical household consumes. The report - funded by an independent grant but done under the auspices of an advocacy group that opposes the signs - concludes that as Philadelphia strives to become the nation's greenest city, a proliferation of digital signs might not be sending the right message.

Renren, China's most popular social network, filed for an initial public offering in the United States on Friday hoping to raise as much as $583 million.
