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...

Green Dot CEO, Mark Remmert; Dan Rocconi, president and CEO of Bixby International; and Eric Chan, internationally recognized designer will form a panel to discuss sustainable product design from material selection to manufacturing at A Better World by Design 2013 Conference hosted by Rhode Island School of Design and Brown University on September 27-29, 2013 in Providence, Rhode Island. Cottonwood Falls, Kansas (PRWEB) September 18, 2013 Green Dot CEO, Mark Remmert, will participate on a...

Bacteria Swim With Help From High-angle Helix
2013-08-13 15:33:24

Brown University It’s counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers at Brown University have figured out why. It's the angle of the coil that matters. Findings are reported in Physical Review Letters. A high-angle helix helps microorganisms like sperm and bacteria swim through mucus and other viscoelastic fluids, according to a new study by researchers from Brown University...

Small Intestine Uses More Cells To Absorb Larger Particles
2013-08-06 07:41:25

Brown University A new study reports that the small intestine uses more cells than scientists had realized to absorb microspheres large enough to contain therapeutic protein drugs, such as insulin. The finding in rats, published in the Proceedings of the National Academy of Sciences, is potentially good news for developing a means for oral delivery of such drugs. The small intestine employs more cells and mechanisms than scientists previously thought to absorb relatively large...
