Bioengineers create functional 3-D brain-like tissue — Tissue model could change the way scientists study the brain in vitro-NIH study – US Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.
Baby hearts need rhythm to develop correctly – To develop correctly, baby hearts need rhythm even before they have blood to pump. “We have discovered that mechanical forces are important when making baby hearts,” said Mary Kathryn Sewell-Loftin, a Vanderbilt graduate student working with a team of Vanderbilt engineers, scientists and clinicians attempting to grow replacement heart valves from a patient’s own cells.
High good and low bad cholesterol levels are healthy for the brain, too – High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, UC Davis researchers have found.
Clinical Trial Shows Tongue-Controlled Wheelchair Outperforms Popular Wheelchair Navigation System – A new study shows that the wireless and wearable Tongue Drive System outperforms sip-and-puff in controlling wheelchairs. In the study, individuals with paralysis were able to use a tongue-controlled technology to access computers and execute commands for their wheelchairs at speeds that were significantly faster than those recorded in sip-and-puff wheelchairs, but with equal accuracy.
Brain may flush out toxins during sleep — NIH-funded study suggests sleep clears brain of damaging molecules associated with neurodegeneration – Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. These results suggest a new role for sleep in health and disease.
Major Changes Urged for Cancer Screening and Treatment — Scientific Panel Recommends New Personalized Strategies to Reduce Cancer Overtreatment – To address the growing problem of people being overdiagnosed and overtreated for cancer, a group of scientists convened by the National Cancer Institute and chaired by a UC San Francisco breast cancer expert is proposing a major update of the way the nation approaches diseases now classified as “cancer.”
Does being a bookworm boost your brainpower in old age? – New research suggests that reading books, writing and participating in brain-stimulating activities at any age may preserve memory. “Our study suggests that exercising your brain by taking part in activities such as these across a person’s lifetime, from childhood through old age, is important for brain health in old age,” said study author Robert S. Wilson, PhD, with Rush University Medical Center in Chicago.
New NIH funding for two Autism Centers of Excellence — A total of 11 centers now funded for up to five years – The National Institutes of Health has awarded $5.3 million in initial one-year funding to the latest two recipients of the Autism Centers of Excellence (ACE) program. With these awards, announced on World Autism Awareness Day, these and nine other ACE centers in US are now being funded for up to five years.
NIH-supported study finds U.S. dementia care costs as high as $215 billion in 2010 — Formal and unpaid dementia care costs are tallied – The costs of caring for people with dementia in the United States in 2010 were between $159 billion to $215 billion, and those costs could rise dramatically with the increase in the numbers of older people in coming decades, according to estimates by researchers at RAND Corp. and the University of Michigan, Ann Arbor.
Next-generation CT scanner provides better images with minimal radiation – A new computed tomography (CT) scanner substantially reduces potentially harmful radiation while still improving overall image quality. National Institutes of Health researchers, along with engineers at Toshiba Medical Systems, worked on the scanner.
