University of Utah biologists invented a chemical-free, hairdryer-like device — the LouseBuster — and conducted a study showing it eradicates head lice infestations on children by exterminating the eggs or “nits” and killing enough lice to prevent them from reproducing.
UCSD bioengineers report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. Scientists have previously published static “snapshots” of the genome sequences of more than 100 bacterial species, but this new report shows how these genomes are moving targets.
Scientists at the University of Michigan Medical School have discovered a previously unknown cause for a severe, early-onset form of kidney disease and renal failure in children: recessive mutations in a gene called phospholipase C epsilon or PLCE1.
In a study published in the November 3 issue of the journal Science, an international group of ecologists and economists shows that the loss of biodiversity is profoundly reducing the ocean’s ability to produce seafood, resist diseases, filter pollutants, and rebound from stresses such as over fishing and climate change.
Physicists from the University of Pennsylvania tackle the fundamental question of how DNA can seemingly violate physics. That is, if DNA is such a rigid molecule, how can it bend and coil without requiring large amounts of force? They used a technique called atomic force microscopy to determine that DNA is much more flexible than previously believed when examined over nano-sized lengths
A protein with the ironic name “Srcasm” can counteract the effects of tumor-promoting molecules in skin cells, according to new research by investigators at the University of Pennsylvania School of Medicine. Using animal models, the researchers discovered that Srcasm acts like a brake in epithelial cells, preventing uncontrolled cell growth caused by a family of proteins called Src kinases. This finding, published online in the Journal of Biological Chemistry, suggests a target for future gene therapy to treat skin, head, neck, colon, and breast cancers.
How well an individual’s immune system controls HIV during the earliest phases of infection appears to depend on both the specific versions of key immune-system molecules called HLA Class I that have been inherited, as well as on the fragments of viral protein those molecules display to the T lymphocytes that usually destroy infected cells. In a report in the November issue of PLOS Medicine, researchers from the Partners AIDS Research Center at Massachusetts General Hospital (PARC/MGH) report that specific HLA Class I/HIV viral fragment combinations are associated with a more powerful antiviral response, findings that may help develop vaccines against HIV.
New Saint Louis University research that outlines the top 10 factors that encourage people to be physically active is a blueprint to design healthier communities.
Developing renewable energy is the only permanent solution to global warming, University of Arizona astronomer Roger Angel concludes. But should Earth be faced with an abrupt climate crisis, a space sunshade is a technically feasible solution.
Kent State University, in partnership with the Louis Stokes Cleveland Department of Veteran Affairs Medical Center, has created a program that offers veterans the opportunity to take control of their future by obtaining entirely online degrees suited to their educational, physical and mental needs.
