Botnet gets the boot
Microsoft has approval to shut down a botnet that was sending out more than a billion spam messages a day. Botnets are essentially a network of slave machines which have been infected with a virus or worm by hackers. Hackers then sell or hire out the botnet to other criminals who use it for fraud, spamming and other cyber crimes. A US court allowed Microsoft to shut down 277 internet domains which were commanding and controlling up to 90,000 infected PCs globally.
How concerned are you about cyber crime?

Snake and spider phobias inborn
Researchers have proven that unborn crickets can gain arachnophobia (fear of spiders) based on their mother's experience. Other research suggests the widespread fear in humans of spiders and snakes may also be inborn. Both adults and children could detect images of snakes or spiders among a variety of non-threatening objects faster than they could find frogs, flowers or caterpillars. Our snake phobia may go back to when snakes were the first predators of early primates.

Fine-tuning fragrance in flowers
Scientists have determined the genes which are responsible for a flower's scent. As a result, they may be able to increase or tune the compounds to result in a particular fragrance. The study also uncovered the location of scent compounds and their interaction with flavour to create fruits which taste better. Expect better tasting tomatoes and better smelling petunias in the future!
If you could change the scent of something, what would it be?
