Researchers at Stanford University have developed a new way of controlling autonomous cars that integrates prior driving experiences—a system that will help the cars perform more safely in extreme and unknown circumstances. Tested at the limits of friction on a racetrack using Niki, Stanford's autonomous Volkswagen GTI, and Shelley, Stanford's autonomous Audi TTS, the system performed about as well as an existing autonomous control system and an experienced racecar driver.

'Smart' pajamas could monitor and help improve sleep

If you've ever dreamed about getting a good night's sleep, your answer may someday lie in data generated by your sleepwear. Researchers have developed pajamas embedded with self-powered sensors that provide unobtrusive and continuous monitoring of heartbeat, breathing and sleep posture—all factors that play a role in how well a person slumbers. The "smart" garments could give ordinary people, as well as clinicians, useful information to help improve sleep patterns.

KAIST team used fuzzing to spot newer LTE protocol vulnerabilities

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) discovered 36 vulnerabilities in 4G LTE wireless networks. Why the stir: Even though there is so much forward-looking talk about next-wave 5G, it is still 4G that is very much in use worldwide, by mobile networks and users.

A Swedish review of out-of-hospital cardiac arrest data shows rates of bystander CPR nearly doubled; compression-only (or Hands-Only CPR) increased six-fold over an 18 year period; and the chance of survival was doubled for any form of CPR compared with no CPR, according to new research in the American Heart Association's journal Circulation.

New evidence on the association of shortened sleep time and OSA with sleepiness and cardiometabolic risk factors

A new study appearing in the journal CHEST may change the way we think about sleep disorders. In this study led by Dr. Luciano F. Drager, obstructive sleep apnea (OSA) and short sleep duration (SSD) were compared with excessive daytime sleepiness; anxiety/depressive symptoms; and several cardiometabolic risk factors including obesity, hypertension, diabetes and dyslipidemia. Using a large sample of adults, investigators found that SSD, but not OSA, was independently associated with daytime sleepiness. In contrast, OSA, but not SSD, was independently associated with obesity, hypertension, and dyslipidemia. Neither was independently associated with anxiety or depression.
