International research team discovers new mechanism behind malaria progression
A team of researchers from four universities, including Carnegie Mellon, has pinpointed one of the mechanisms responsible for the progression of malaria, providing a new target for possible treatments. Using computer modeling, the group found that nanoscale knobs, which form at the membrane of infected red blood cells, cause the cell stiffening that is in part responsible for the reduced blood flow that can turn malaria deadly.

New UW app can detect sleep apnea events via smartphone
The gold standard for diagnosing sleep apnea -- a disease which affects roughly 1 in 13 Americans -- requires an overnight hospital stay and costs thousands of dollars. A new smartphone app developed at the University of Washington can wirelessly test for sleep apnea events in a person's own bedroom without needing special sensors attached to the body.

Model uncovers malaria parasite causes red blood cell changes
A model of a malaria-infected red blood cell may lead to better ways to treat malaria, according to a team of engineers and molecular biologists who investigated how this parasite infection causes the red blood cells to stiffen.

Two-dimensional semiconductor comes clean
Columbia Engineering Professor James Hone led a team in 2013 that dramatically improved the performance of graphene by encapsulating it in boron nitride. They've now shown they can similarly improve the performance of another 2-D material, molybdenum disulfide. Their findings provide a demonstration of how to study all 2-D materials and hold great promise for a broad range of applications including high-performance electronics, detection and emission of light, and chemical/bio-sensing.

The waters of Baja California Sur are both ecosystems and fisheries where human needs meet nature. In a new study, researchers assessed the capacity to achieve sustainability by applying a framework that accounts for both ecological and human dimensions of environmental stewardship.

Northwestern scientists develop first liquid nanolaser
Northwestern University scientists have developed the first liquid nanoscale laser. And it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a 'lab on a chip' for medical diagnostics. In addition to changing color in real time, the liquid nanolaser has additional advantages: it is simple to make, inexpensive to produce and operates at room temperature.

Generating broadband terahertz radiation from a microplasma in air
Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. In a paper published this week in Optica, they demonstrate that an approach for generating terahertz waves using intense laser pulses in air can be done with much lower power lasers, a major challenge until now. Lead author Fabrizio Buccheri explains that they exploited the underlying physics to reduce the necessary laser power for plasma generation.

Going with the flow?
Soil scientists have struggled with accurately measuring water flow through soil for years. Even the smallest soil details can sway water's path from the straight, sequential line gravity alone might demand. These minute differences contribute to water's 'preferential flow.' This study examined methods to scale up observations from the smallest, basic unit of soil to the larger landscape and found the unique water patterns depended small-scale elements.

Revolutionary discovery leads to invention of new 'building blocks'
Taking a revolutionary 'building blocks' approach, a research team led by Stephen Z.D. Cheng at the University of Akron invented a new thinking pathway in the design and synthesis of macromolecules by creating an original class of giant tetrahedra. Through a reaction called 'click chemistry,' these tetrahedron building blocks can then be precisely manipulated to unite with other tetrahedrons.

Scientists see deeper Yellowstone magma
University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times, while the previously known magma chamber would fill the Grand Canyon 2.5 times.

UNH researchers discover new method to detect most common bacteria contaminating oysters
In a major breakthrough in shellfish management and disease prevention, researchers at the University of New Hampshire have discovered a new method to detect a bacterium that has contaminated New England oyster beds and sickened consumers who ate the contaminated shellfish. The new patent-pending detection method - which is available for immediate use to identify contaminated shellfish -- is a significant advance in efforts to identify shellfish harboring disease-carrying strains of Vibrio parahaemolyticus.

Drexel materials scientists putting a new spin on computing memory
As computers continue to shrink -- moving from desks and laps to hands and wrists -- memory has to become smaller, stable and more energy conscious.

CWRU researcher awarded $500,000 NSF CAREER grant
A Case Western Reserve University researcher has won a $500,000 National Science Foundation grant to create tiny sensors capable of detecting insecticides in Lake Erie or determining subtypes of human cancers. The sensors are designed to detect multiple cancer markers or environmental hazards at the same time and with greater sensitivity than what's currently available. The results could be used for personalized medicine or to more quickly identify pollutants and begin subsequent clean-up efforts.
