Now, CCTV that can ‘sense’ aggression

A UK company has developed a CCTV technology, which can make out if you’re being aggressive or calling for help. What’s more, it will alert security guards straight away.
The Cambridge firm Audio Analytic has produced a software, which can analyse the pitch, tone and intonation of noises and work out if they pose a threat.

“Our system picks out the most salient characteristics. A lot of incidents just can’t be picked up by video only systems. For example in a hospital where somebody, that’s a very difficult thing for CCTV guards who monitor hundreds of channels worth of video signals on many screens to pick up,” he explained.

The software essentially contains hundreds of audio fingerprints, and as soon as a sound resembles a stored sample, the alarm is raised. However, like any software early in its development, there are a few loopholes in the technology but Mitchell’s team is confident the technology is ready to get out into the market.

Coming soon: Captcha ads you just can’t ignore

Software firm NuCaptcha believes the answer lies in ‘captchas’, as they require a user’s full attention to solve. The firm has created NuCatpcha Engage to exploit this. Instead of the traditional squiggly word that users have to decipher, the new system shows them a video advert with a short message scrolling across it. The user has to identify and retype part of the message to proceed.

Breast density linked to breast cancer risk

A new study has found that women with dense breasts and no lobular involution are at a higher risk for developing breast cancer than those with non-dense breasts and complete involution.

To determine whether these two factors are independently associated with breast cancer risk, Karthik Ghosh, of the Mayo Clinic, and colleagues investigated the factors’ association with breast cancer risk in a cohort of 2,666 women with benign breast disease.

The researchers found that breast density and extent of lobular involution were independent risk factors for breast cancer, and that combined, they pose an even greater risk.

Future studies, they write, should include larger numbers of patients from diverse racial and ethnic backgrounds and aim to understand the relationship between involution and epidemiological risk factors such as body mass index.
