Martian Debris May Also Be Found On Phobos
2013-11-12 04:17:26

[ 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...

Single Mutation Gives Virus A New Target
2013-10-22 13:34:16

Brown University In a new study published online in the journal PLoS Pathogens, an international team of scientists showed that by swapping a single amino acid they could change the sugar to which the human BK polyomavirus will bind on the surface of cells. The BK polyomavirus lost the ability to bind its usual target sugar and instead “preferred” the same sugar as its cousin SV40 polyomavirus, which is active in monkeys. The researchers were working in cell cultures with safe...

Humans And Rodents Process Their Mistakes
2013-10-21 06:55:57

Brown University Study finds parallels in neural processing of 'adaptive control' People and rats may think alike when they've made a mistake and are trying to adjust their thinking. That's the conclusion of a study published online Oct. 20 in Nature Neuroscience that tracked specific similarities in how human and rodent subjects adapted to errors as they performed a simple time estimation task. When members of either species made a mistake in the trials, electrode recordings showed...

Researchers from Brown University and King's College London have gained surprising new insights into how brain anatomy influences language acquisition in young children. Their study, published in the Journal of Neuroscience, found that the explosion of language acquisition that typically occurs in children between 2 and 4 years old is not reflected in substantial changes in brain asymmetry. Structures that support language ability tend to be localized on the left side of the brain. For...

Meals For Seniors Could Save Money For Some States
2013-10-07 16:44:42

Brown University Home-delivered meals bring not only food to seniors but also the opportunity to remain in their homes. A new study by Brown University public health researchers projects that if every U.S. state in the lower 48 expanded the number of seniors receiving meals by just 1 percent, 1,722 more Medicaid recipients avoid living in a nursing home and most states would experience a net annual savings from implementing the expansion. Pennsylvania would see the greatest net savings...

A research team centered at Brown University has compiled the largest and most stringently validated list of RNA editing sites in the fruit fly Drosophila melanogaster, a stalwart of biological research. Their research, which yielded several insights into the model organism's fundamental biology, appears Sept. 29 in Nature Structural & Molecular Biology. The "master list" totals 3,581 sites in which the enzyme ADAR might swap an "A" nucleotide for a "G" in an RNA molecule. Such a...
