Jawbone unleashes Big Jambox, beefs up its Bluetooth 'smartspeaker' lineup
We've had a shimmer in our eye for Jawbone's $200 Jambox, the itty bitty Bluetooth 'smartspeaker,' ever since it was released back in late 2010. So, imagine our delight now that the company has just stepped things up to a larger level with its new $300 Big Jambox. Measuring in at well over double the size of the original, the 2.7-pound speaker is still very similar in design and features the familiar perforated metal grill designs by Yves Behar -- starting May 15th, you can pick one up in your choice of Red Dot, Graphite Hex and White Wave. The larger footprint helps it to be more functionally capable than its sibling, yet it's still small enough to carry in one hand. On top, the unit sports playback controls in addition to the requisite volume and talk buttons, while on the side you'll find a USB connection (for software updates), power input 3.5mm jack, Bluetooth-pairing button and a power button.
To pump out the jams, the Big Jambox features an airtight enclosure loaded with a duo of active neodymium drivers and opposing dual-passive bass radiators to handle all the wub wub you can throw at it. A 2,600mAh rechargeable battery will get you roughly 15 hours of totally wireless listening time (500 on standby), but -- as is the case with the original -- you still can't share that juice with your gadgets. Positivey, Android users can take advantage of the Big Jambox's exclusive Companion app, which allows the unit to do tricks such like sync up with your G-cal to inform you about your appointments. Lastly, like the Jambox, the Big Jambox features MyTalk voice prompts / app compatibility, along with Live Audio DSP to give your sounds an immersive "3D" feel. Curious to find out more? We spent a full weekend with the new gizmo, and you can catch our full review by clicking here. Full press release after the break

Decision support system translates into high percentage of positive chest CT examinations

Using a decision support system for ordering chest CT examinations translates into positive examinations three-quarters of the time, a new study shows.
The study, conducted at Massachusetts General Hospital in Boston, of 93,818 chest CT examinations done with the assistance of a decision support system, found that 76% of patients had a positive finding on their CT.
"Rising concerns about radiation risks, imaging growth and reimbursement costs has highlighted inappropriate imaging use," said Dr. Supriya Gupta, MD, one of the authors of the study. The decision support system provides a "utility score" for the test being ordered, said Dr. Gupta. When faced with low utility scores, referring physicians may choose to modify their imaging request, cancel the examination, order a different type of examination or proceed with the order. The study found that only 12% of the examinations with a low utility score translated into a positive finding, said Dr. Gupta. That compares to 87% for those with a high utility score, she said.
The study also reviewed utilization. Utilization was highest when abnormal chest radiography, shortness of breath or persistent cough was listed as the indication for performing chest CT, Dr. Gupta said.
The study will be presented on May 1 at the 2012 American Roentgen Ray Society Annual Meeting in Vancouver, Canada.
