A new study by Johns Hopkins Bloomberg School of Public Health researchers shows that the risk of developing HPV-related throat cancer remains generally low.

New study shows TBI laws effective at reducing rate of recurrent concussions

EurekAlert! - Mié, 10/18/2017 - 22:00
A recent study from the Center for Injury Research and Policy at Nationwide Children's Hospital done in conjunction with researchers from Colorado School of Public Health at the University at Colorado and Temple University used data from a large, national sports injury surveillance system to determine the effect of state-level TBI laws on trends of new and recurrent concussions among US high school athletes.

Sequencing of stevia plant genome revealed for first time by Purecircle Stevia Institute

EurekAlert! - Mié, 10/18/2017 - 22:00
For the first time, scientists have completed the sequencing of the stevia plant genome. Lead scientists from PureCircle Stevia Institute and KeyGene have unveiled this major breakthrough in research showing the annotated, high-quality genome sequences of three stevia cultivars.

Field trips of the future?

EurekAlert! - Mié, 10/18/2017 - 22:00
Biologist Douglas McCauley examines the benefits and drawbacks of virtual and augmented reality in teaching environmental science.

Researchers pinpoint causes for spike in breast cancer genetic testing

EurekAlert! - Mié, 10/18/2017 - 22:00
A sharp rise in the number of women seeking BRCA genetic testing to evaluate their risk of developing breast cancer was driven by multiple factors, including celebrity endorsement, according to researchers at the University of Georgia.

Research yields test to predict bitter pit disorder in Honeycrisp apples

EurekAlert! - Mié, 10/18/2017 - 22:00
A test to determine whether bitter pit -- a disorder that blindsides apple growers by showing up weeks or months after picking -- will develop in stored Honeycrisp apples was developed by a team of Penn State researchers, promising to potentially save millions of dollars annually in wasted fruit.

Researchers find evidence of DNA damage in veterans with Gulf War illness

EurekAlert! - Mié, 10/18/2017 - 22:00
Veterans Affairs researchers say they have found the 'first direct biological evidence' of damage in veterans with Gulf War illness to DNA within cellular structures that produce energy in the body.

NASA sees intensifying Typhoon Lan stretch high in the troposphere

EurekAlert! - Mié, 10/18/2017 - 22:00
NASA's Global Precipitation Measurement mission or GPM satellite provided 3-D data that showed intensifying Typhoon Lan had powerful thunderstorms stretching high into the troposphere. NASA-NOAA's Suomi NPP satellite provided a visible image Typhoon Lan that showed the well-developed circulation.

Using optical chaos to control the momentum of light

EurekAlert! - Mié, 10/18/2017 - 22:00
Controlling and moving light poses serious challenges. One major hurdle is that light travels at different speeds and in different phases in different components of an integrated circuit. For light to couple between optical components, it needs to be moving at the same momentum. Now, a team of researchers has demonstrated a new way to control the momentum of broadband light in a widely-used optical component known as a whispering gallery microcavity (WGM).

Number of newly diagnosed cancer patients without insurance drops in first year of ACA

EurekAlert! - Mié, 10/18/2017 - 22:00
The number of newly diagnosed cancer patients who were uninsured fell by one-third in the first year of the Affordable Care Act's implementation, according to research from Indiana University.

The blob that ate the tokamak: Physicists gain understanding of bubbles at edge of plasmas

EurekAlert! - Mié, 10/18/2017 - 22:00
Scientists at PPPL have completed new simulations that could provide insight into how blobs at the plasma edge behave. The simulations, produced by a code called XGC1 developed by a national team based at PPPL, performed kinetic simulations of two different regions of the plasma edge simultaneously.

New tyrannosaur fossil is most complete found in southwestern US

EurekAlert! - Mié, 10/18/2017 - 22:00
A fossilized skeleton of a tyrannosaur discovered in Utah's Grand Staircase-Escalante National Monument was airlifted by helicopter Oct. 15, and delivered to the Natural History Museum of Utah where it will be uncovered, prepared, and studied. The fossil is approximately 76 million years old and is likely an individual of the species Teratophoneus curriei.

Suicide molecules kill any cancer cell

EurekAlert! - Mié, 10/18/2017 - 22:00
A super assassin hidden in every cell forces the cell to commit suicide if it becomes cancerous, reports a new study, the first to identify molecules to trigger a fail-safe mechanism that may protect us from cancer. The mechanism -- RNA suicide molecules -- can potentially be developed into a novel form of cancer therapy. Cancer cells treated with the RNA molecules never become resistant to them because they simultaneously eliminate multiple genes that cancer cells need for survival.

Key psychiatric drug target comes into focus

EurekAlert! - Mié, 10/18/2017 - 22:00
One way or another, many psychiatric drugs work by binding to receptor molecules in the brain that are sensitive to the neurotransmitter dopamine, a chemical signal that is central to how our experiences shape our behavior. But because scientists still don't understand the differences between the many kinds of dopamine receptors present on brain cells, most of these drugs are 'messy,' binding to multiple different dopamine receptor molecules and leading to serious side effects ranging from movement disorders to pathological gambling.

Renewable resource: To produce vital lipoic acid, sulfur is used, then replenished

EurekAlert! - Mié, 10/18/2017 - 22:00
New research shows how a protein is consumed, then reconstituted, during the production of a compound required for converting energy from food into a form that can be used by our cells. The results could help scientists to understand why humans with a fatal condition -- defects in an iron-sulfur carrier gene -- have deficiencies in this lipoic acid compound.

Water striders illustrate evolutionary processes

EurekAlert! - Mié, 10/18/2017 - 22:00
How do new species arise and diversify in nature? Natural selection offers an explanation, but the genetic and environmental conditions behind this mechanism are still poorly understood. Researchers have just figured out how water striders (family Veliidae) of the genus Rhagovelia developed fan-like structures at the tips of their legs. These structures allow them to move upstream against the current, a feat beyond the abilities of other water striders that don't have fans.
