Review: Symantec has moved Norton 360 to the same release schedule as Norton Internet Security and Norton AntiVirus, making them into a three-tiered strategy for consumer security. Norton AntiVirus is the entry-level product, with Norton Internet Security occupying the middle rung and Norton 360 aimed at people who want the most bang for the most buck.

Notoriously slow to respond to trends, the consumer security field is surprisingly not taking Windows 8 lying down. Norton and many of its competitors are optimizing their suites for Microsoft's new operating system ahead of its release, and Norton is combining that strategy … Read more

Two separate studies published this month indicate that it may be possible to use brain imaging techniques to reliably detect autism in children as young as 6 months of age.

In the first study, published in the American Journal of Psychiatry, researchers from across North America working on the larger and ongoing Infant Brain Imaging Study used a type of MRI called diffusion tensor imaging to study 92 6-month-olds deemed high risk because their older siblings had been diagnosed with autism.

What they found is that the organization of white matter in the brain plays a key role. Specifically, they … Read more

Of the 50 million people worldwide estimated to have epilepsy, almost a third do not respond to treatment. Those patients must rely on implantable anti-seizure devices that detect pre-seizure electrical activity and shoot small electrical impulses to the brain to interrupt the seizures.

The downside is that the tech, still early in development, also produces false positives, causing devices to send currents to the brain when a seizure is not actually occurring. One new approach, developed by a biomedical and electrical engineer at Johns Hopkins University, appears to reduce those false alarms.

Tested on real-time recordings of brain activity in … Read more

Modern tech cars can be equipped with a host of driver aid systems that help make driving easier for your average commuter. From road-aware cruise control systems to self-aware headlight systems, cars are getting smarter every day.

Adaptive cruise control If the standard cruise control system was the first step toward vehicular autonomy, then adaptive cruise control system is … Read more

Engineers at Mountain View, Calif.-based SST have come up with technology that uses acoustic sensors to help police pinpoint the exactly location of a gunshot as soon has it goes off.

SmartPlanet visited the San Francisco Police Department to see SST's gunfire-detection software in action.
