Ultrasound device could help detect cause of heart attack and stroke

By - April 27, 2014 1 Picture
While existing ultrasound technologies are able to identify plaque buildup on artery walls, determining when that plaque is at risk of breaking off, resulting in a heart attack or stroke, has proven a more complicated task. A team of researchers from North Carolina State University has now developed a dual-frequency ultrasound device that could help identify so-called vulnerable plaque and enable a more accurate diagnosis for at-risk patients.

Tiny probe designed to provide live 3D images from within blood vessels

By - February 24, 2014 1 Picture
Imagine if you were trying to clear rubble out of a tunnel, but you could only see that tunnel from the side, instead of looking straight into it. Well, that's currently what it's like for doctors who are trying to see inside patients' blocked coronary blood vessels using ultrasound. Soon, however, a tiny catheter-based probe may give them a 3D real-time forward view from inside those vessels – or from inside the heart itself – not unlike that seen by the microscopic submarine crew in the movie Fantastic Voyage.

Gemini Planet Imager snaps first direct image of exoplanet Beta Pictoris b

By - January 9, 2014 7 Pictures
Following almost 10 years of development, the Gemini Observatory has debuted an advanced planet imaging instrument and captured a direct image of exoplanet Beta Pictoris b, signifying a breakthrough in our ability to analyze extrasolar planets. Called the Gemini Planet Imager (GPI), the tool uses an advanced optics system with an infrared spectograph to retrieve direct images of young planets orbiting distant stars. Read More

A good book can change your life ... and your brain

By - January 5, 2014 2 Pictures
Stories, whether fact or fiction, are at the heart of human culture. A strong narrative can resonate with your personality and experiences, and help set a framework for your future. "That book changed my life" is a cherished maxim. So can a book change your brain too? A recent study led by Emory University's Gregory Berns has demonstrated that reading a novel produces physical changes in the brain similar to those that would result from living as one or more of the characters.
