Rutgers neuroscience may hold key to hearing loss remedy
- EurekAlert
- 07/12/18 06:00
A Rutgers University team is opening new doors to improved hearing for the congenitally or profoundly deaf. They researchers found that two neurotrophin proteins in the cochlea -- brain-derived neurotrophic factor and neurotrophin-3 -- figure prominently in the relay of sound messages to the brain. The research is showing precisely how these multidimensional proteins operate in the cochlea. Their...
Safer, more accurate radiation therapy for expecting mothers
- EurekAlert
- 07/12/18 06:00
Developing fetuses are extremely sensitive to radiation, which poses an impossible dilemma for expecting mothers in need of screening or treatment for cancer. Now researchers from Rensselaer Polytechnic Institute have developed a new set of modeling tools that could enable safer, more accurate, and more effective radiation therapy and nuclear medicine imaging procedures for pregnant women.
Sandia supercomputers offer new explanation of Tunguska disaster
- EurekAlert
- 07/12/18 06:00
The stunning amount of forest devastation at Tunguska a century ago in Siberia may have been caused by an asteroid only a fraction as large as those postulated in previously published estimates, Sandia supercomputer simulations suggest. Because there are more smaller asteroids than larger ones, the need to guard against such impacts may be greater than previously thought.
Simple strategy could prevent half of deadly tuberculosis infections

Study examines imaging procedures for diagnosing blood clots in the lung
- EurekAlert
- 07/12/18 06:00
New research indicates that a diagnostic strategy using computed tomographic pulmonary angiography may be a safe alternative to conventional lungs scans (known as ventilation-perfusion scans) for excluding the diagnosis of pulmonary embolism (blood clots in the lung vessels), although CTPA may detect more clots, according to a study in the Dec. 19 issue of JAMA.
Study finds outcomes of high-risk cancer operations in 80-year-olds worse than reported
- EurekAlert
- 07/12/18 06:00
New research published in the December issue of The Journal of the American College of Surgeons shows that outcomes of high-risk cancer operations in 80-year-olds are considerably worse than reported in case studies and published survival statistics, which may lead to unrealistic expectations about the safety of these operations in the elderly.
Study investigates cannabis use among university students
- EurekAlert
- 07/12/18 06:00
New information published in the Journal of Applied Biobehavioral Research explores University students' motivations for using or not using cannabis and found various factors that might encourage use.
Study of bear hair will reveal genetic diversity of Yellowstone's grizzlies
- EurekAlert
- 07/12/18 06:00
Montana State University's library of 400 grizzly bear hair samples will be analyzed to determine the genetic diversity of the Greater Yellowstone Ecosystem population. The study will also determine if bears from the Northern Continental Divide Ecosystem are adding their genetic diversity to the Yellowstone group.
Study suggests polls overestimate support for Obama, underestimate back for Clinton
- EurekAlert
- 07/12/18 06:00
A new national study of voters who say they might vote in Democractic primaries and caucuses shows a striking disconnect between their explict and their implicit (or unconscious) preferences.
Top 10 advances in materials science selected by Materials Today
- EurekAlert
- 07/12/18 06:00
What are the defining discoveries and great developments that are shaping the way we use materials and technologies today? Elsevier's Materials Today magazine has compiled a list of the top ten most significant advances in materials science over the last 50 years.
Twin study indicates genetic basis for processing faces, places
- EurekAlert
- 07/12/18 06:00
A new study of twins indicates that the genetic foundation for the brain's ability to recognize faces and places is much stronger than for other objects, such as words. The results, which appear in the Dec. 19 issue of the Journal of Neuroscience, are some of the first evidence demonstrating the role of genetics in assigning these functions to specific regions of the brain.

A new Web-based software program is the latest tool University of Minnesota researchers are using to help fight the spread of HIV.
Unique porous copper structure enables new generation of military micro-detonators
- EurekAlert
- 07/12/18 06:00
Tiny copper structures with pores at both the nanometer and micron size scales could play a key role in the next generation of detonators used to improve the reliability, reduce the size and lower the cost of certain military munitions.
University of Maryland researchers develop 2-D invisibility cloak
- EurekAlert
- 07/12/18 06:00
A University of Maryland research team has used plasmon technology to create the world's first invisibility cloak for visible light. The engineers have applied the same technology to build a revolutionary superlens microscope that allows scientists to see details of previously undetectable nanoscale objects.
