Technique Allows for Non-Invasive Liver Analysis and Improved Patient Outcomes East Providence, RI (PRWEB) December 18, 2013 Rhode Island Medical Imaging (RIMI) has expanded its wide-range of diagnostic services to now include liver elastography. This non-invasive procedure has proven successful for assessing liver fibrosis and cirrhosis, with virtually no patient risk. RIMI is currently the only out-patient imaging center to offer liver elastography, and it is not yet available at local...

Neuroscience Method Of Optogenetics As Good As Electrical Stimulation
2013-12-12 17:27:06

Brown University Neuroscientists are eagerly, but not always successfully, looking for proof that optogenetics – a celebrated technique that uses pulses of visible light to genetically alter brain cells to be excited or silenced – can be as successful in complex and large brains as it has been in rodent models. A new study in the journal Current Biology may be the most definitive demonstration yet that the technique can work in nonhuman primates as well as, or even a little better...

Lunar Impact Crater Has A Diverse Subsurface Mineralogy
2013-12-10 05:53:55

redOrbit Staff & Wire Reports - Your Universe Online The presence of a diverse group of minerals in the largest lunar impact crater could help scientists gain new insight into the Moon’s interior, as well as the evolution of its crust and mantle, claims new research appearing online in Journal of Geophysical Research: Planets. Dan Moriarty, a graduate student from Brown University, and his colleagues analyzed data collected from the Moon Mineralogy Mapper instrument aboard India's...

Non-IVF treatments become bigger contributor Fertility technology in the United States has a huge influence on the frequency of twins, triplets, and other multiple births, according to new estimates published Dec. 5 in the New England Journal of Medicine. Dr. Eli Y. Adashi, professor of obstetrics and gynecology at Brown University, and his colleagues calculated that more than a third of twin births and more than three-quarters of triplets or higher-order births in the United States in...

Researchers from Brown University and Banner Alzheimer's Institute have found that infants who carry a gene associated with increased risk for Alzheimer's disease tend to have differences in brain development compared to children without the gene. The study, published in JAMA Neurology, demonstrates some of the earliest developmental differences associated with a gene variant called APOE-E4, a common genotype and a known risk factor for late-onset Alzheimer's. The researchers imaged the...

Rhode Island Medical Imaging Emphasizes the Importance of Screenings East Providence, RI (PRWEB) November 13, 2013 To commemorate National Radiology Month, Rhode Island Medical Imaging (RIMI) would like to inform patients on the importance of screening for those people with certain risk factors. Diagnostic imaging is the most accurate testing available for many diseases and ailments, including lung cancer, breast cancer, and osteoporosis. RIMI created the first comprehensive outpatient...

[ Watch the Video: Phobos Mission Could Return With Bonus Martian Material ] redOrbit Staff & Wire Reports - Your Universe Online Call it the geological equivalent of a buy-one, get-one free special: a planned Russian mission to collect samples from the Martian moon Phobos could also net debris from the Red Planet itself, according to research appearing in the journal Space and Planetary Science. The study, which was authored by Brown University professor of geological sciences...

How Sleep Helps Visual Task Learning
2013-11-11 07:31:12

Brown University As any indignant teacher would scold, students must be awake to learn. But what science is showing with increasing sophistication is how the brain uses sleep for learning as well. At the annual meeting of the Society for Neuroscience in San Diego Nov. 10, 2013, Brown University researchers will discuss new research describing the neural mechanism by which the sleeping brain locks in learning of a visual task. The mounting evidence is that during sleep the brain employs...

Edited RNA Plus Invasive DNA Add Individuality
2013-11-08 08:19:46

Brown University A study in Nature Communications finds that an enzyme that edits RNA may loosen the genome’s control over invasive snippets of DNA that affect how genes are expressed. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span. The story of why we are all so different goes well beyond the endless mixing and matching of DNA through breeding. A new study in the journal Nature Communications, for...

Using Gold Nanoparticles To Convert Carbon Dioxide To Carbon Monoxide
2013-10-25 09:25:35

Brown University It’s a 21st-century alchemist’s dream: turning Earth’s superabundance of carbon dioxide — a greenhouse gas — into fuel or useful industrial chemicals. Researchers from Brown have shown that finely tuned gold nanoparticles can do the job. The key is maximizing the particles’ long edges, which are the active sites for the reaction. By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a catalyst that selectively...
