Spam is a massive problem - it currently accounts for between 1/3 and 1/2 of all emails and costs companies billions of dollars as the result of lower productivity, loss of legitimate messages and the need for increased bandwidth and storage. In a bid to try solve the problem, IBM has brought together scientists from different areas of research division to develop an enterprise anti-spam filtering system which combines several different filtering technologies to create the ultimate anti-spam system. For example one of the spam filters - Chung-Kwei - is a pattern-discovery-based system which uses an algorithm developed by life sciences researchers focused tackling computational biology challenges such as gene finding and protein annotation. By itself, Chung-Kwei detected 96.56 percent of spam messages with just a .066 percent false positive rate during tests conducted in IBM’s labs. By combining Chung-Kwei with the other spam filtering techniques, IBM researchers have created SpamGuru - a prototype anti-spam system which they believe has the potential to eliminate virtually all spam.
SpamGuru: An Enterprise Anti-Spam Filtering System
IBM Research is developing an enterprise-class anti-spam filter as part of our overall strategy of attacking the Spam problem on multiple fronts. Our anti-spam filter, SpamGuru, mirrors this philosophy by incorporating several different filtering technologies and intelligently combining their output to produce a single spamminess rating or score for each incoming message. The use of multiple algorithms improves the system’s effectiveness and makes it more difficult for spammers to attack. While a spammer may defeat any single algorithm, SpamGuru can rely on its remaining algorithms to maintain a high-degree of effectiveness.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
