When we have a conversation with someone, we not only hear what they say, we see what they say. Eyes can smolder or twinkle. Gazes can be direct or shifty. “Reading” these facial expressions gives context and meaning to the words we hear.
Gene mutation linked to increased athletic performance in whippets
Whippets are bred for speed and have been clocked at speeds approaching 40 miles per hour over a 200-yard racing course. Scientists at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), have now discovered a genetic mutation that helps to explain why some whippets run even faster than others. more
Common genetic variation is linked to substantial risk in heart attack
A common genetic variation on chromosome 9p21 is linked to a substantial increase in risk for heart attack, according to a new international research study. The findings are published today in the online edition of Science, and will appear in an upcoming printed edition of the journal. more
MDCT eliminates need for catheter angiography for aortic injury diagnosis, saving time and lives
Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston. more
Nearly 28,000 US infants died in 2004
Preterm birth contributes to more than one-third of all infant deaths, according to the National Vital Statistics report released today.
Ultra-high-field MRI allows for earlier diagnosis of multiple sclerosis
Ultra-high-field (7T) MRI can detect multiple sclerosis lesions better than MRI which can lead to possible earlier diagnosis and treatment, according to a new study by researchers from Ohio State University in Columbus, and Columbia University in New York. more
MR imaging helps predict recurrence in prostate cancer patients
MR images taken of prostate cancer patients prior to treatment that show that the cancer has spread outside the prostate gland capsule help predict whether the cancer will return, according to a recent study conducted by radiologists at the University of California-San Francisco. more
