The BBC is reporting that a plan for a cloaking device has been unveiled. The design is pioneered by Professor Sir John Pendry's team of scientists from the US and Britain. Proof of the ability of his invention could be ready in just 18 months time using radar testing. The method revolves around certain materials making light "flow" around the given object like water

Extreme Life on Earth
Our oceans are 99% unexplored. In the past 30 years, we have discovered 3 ecosystems that don't directly depend on light for their survival. We never even guessed these ecosystems were possible. What other surprises will we find as we continue to explore the ocean floor?

Traffic junctions of the future
How will be the traffic flow in the future. Check this similuation. The average car delay now is 10 seconds. This simulation brings it down to 0.47 seconds or even in some cases, 0.076 seconds. Amazing to watch
Gone in 20 Minutes: using laptops to steal cars
From the article:
High-tech thieves are becoming increasingly savvy when it comes to stealing automobiles equipped with keyless entry and ignition systems. While many computer-based security systems on automobiles require some type of key — mechanical or otherwise — to start the engine, so-called ‘keyless’ setups require only the presence of a key fob to start the engine
Targeted virus compels cancer cells to eat themselves
From the article:
An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report this week in the Journal of the National Cancer Institute
The modified adenovirus homed in on malignant glioma cells in mice and induced enough self-cannibalization among the cancer cells -- a process called autophagy -- to reduce tumor size and extend survival, says senior author Seiji Kondo, M.D., Ph.D., associate professor in the Department of Neurosurgery at M. D. Anderson.
''This virus uses telomerase, an enzyme found in 80 percent of brain tumors, as a target,'' Kondo says. ''Once the virus enters the cell, it needs telomerase to replicate. Normal brain tissue does not have telomerase, so this virus replicates only in cancer cells.''

Make'em drink coffee, if you want them say YES
According to an Australian study, our geek wonder-drink of choice might turn us into yes-men. From the article: "The experiments showed that "caffeine increases persuasion through instigating systematic processing of the message"." Apparently this has implications for the advertising world, "because it suggests that they should schedule adverts for times when people are likely to be consuming caffeine, such as breakfast time.".
