Wireless solution to emergency situations
|
Recent emergency situations that have arisen in the UK, including severe flooding, extreme weather, and even terrorist attacks have highlighted repeatedly just how vulnerable some sections of society can be in such circumstances. UK researchers suggest that wireless technology could hold the key to remedying this problem.

Leaf veins inspire a new model for distribution networks
|
A straight line may be the shortest path from A to B, but it's not always the most reliable or efficient way to go. In fact, depending on what's traveling where, the best route may run in circles, according to a new model that bucks decades of theorizing on the subject. A team of biophysicists have developed a mathematical model showing that complex sets of interconnecting loops -- like the netted veins that transport water in a leaf -- provide the best distribution network for supplying fluctuating loads to varying parts of the system. It also shows that such a network can best handle damage.

Computer scientists have shown how a familiar type of personal computer security threat can now attack new generations of smart mobile phones, with the potential to cause more serious consequences. The researchers demonstrated how such a software attack could cause a smart phone to eavesdrop on a meeting, track its owner's travels, or rapidly drain its battery to render the phone useless.

Code defends against 'stealthy' computer worms

Self-propagating worms are malicious computer programs, which, after being released, can spread throughout networks without human control, stealing or erasing hard drive data, interfering with pre-installed programs and slowing, even crashing, home and work computers. Now a new code, or algorithm, created by researchers targets the "stealthiest" of these worms, containing them before an outbreak can occur.

For a generation of students raised and nurtured at the computer keyboard, it seems like a no-brainer that computer-assisted learning would have a prominent role in the college science classroom. But many difficult scientific concepts are still conveyed through dry lectures or ponderous texts. But that could change if science professors take a cue from a new study on the use of interactive animations in the college science classroom.

A cheap way to deliver interactive communications to remote communities has been successfully tested in Brazil and Italy. Digital television signals with java applications embedded within them were broadcast by the SAMBA project into the small Brazilian town of Barreirinhas which is 300km from the nearest major city. Some 30 Barreirinhas households, in the vicinity of a 3km power line, were equipped with special set-top boxes that enabled them to access the broadcast data.
