Boys with the longest ring fingers relative to their index fingers tend to excel in math, according to a new study. In girls, shorter ring fingers predict better verbal skills. The link, according to the researchers, is that testosterone levels in the womb influence both finger length and brain development.

Like a house being built from the inside out, brain development must proceed in a precise order. Otherwise, everything falls apart. The brain is constructed from neural progenitor cells, which give rise to all the neuron types found in the cerebral cortex. Now scientists have now found that these cells are the architects as well, determining which layers of the cerebral cortex are assembled during various points in development. Researchers say the finding places important restrictions on the potential therapeutic use of neural stem cells.

In the largest and most comprehensive code-level security analysis to date, Veracode, the leader in cloud-based application risk management, today released a new report detailing vulnerabilities found in software that large organizations rely on for business critical processes. The Veracode "State of Software Security" report finds that more than half of the nearly 1,600 Internally Developed, Open Source, Outsourced, and Commercial applications analyzed when first submitted to Veracode contained vulnerabilities similar to those exploited in the recent cyber attacks on Google, the U.S. Department of Defense, and others.

Are you a Facebook user? How secure is Facebook?

What will Facebook do if the Russian hacker Kirllos' claim that he has in his possession login credentials for 1.5 million Facebook accounts proves to be true? The hacker was spotted offering the credentials for sale on an underground forum. An image of the post in question was posted on Twitter by Mikko Hyponnen, CRO at F-Secure: Kirllos asks from $25 to $45 per 1,000 accounts (that's $0.025/$0.045 per account), and according to VeriSign's Director of Cyber Intelligence Rick Howard, he has already been able to sell almost half of the total number. If the credentials are legitimate and the accounts exist, that means that 1 in every 300 accounts is compromised, and can be used by the buyers to prey on other users by spamming and scamming them - not to mention, to direct them towards sites serving malware. And people are more likely to fall for such tricks, since they have a tendency to trust other users that are encompassed in their (online) social circle. Facebook has yet to comment on the whole situation.
