Shifts in states of matter: It’s complicated

November 7, 2014 | by Anne M. Stark, LLNL | Comments

The process of phase changes- those transitions between states of matter- is more complex than previously thought. A team researchers has found that we may need to rethink one of science’s building blocks and illustrate how a proper theoretical description of transitions has remained unclear.

Blu-ray disc can be used to improve solar cell performance

November 25, 2014 8:23 pm | by Northwestern Univ. | Comments

Who knew Blu-ray discs were so useful? Already one of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to new research from Northwestern Univ.

Want a Nobel Prize? You can buy one

November 25, 2014 5:03 pm | by Associated Press | Comments

The 1962 Nobel Prize James Watson won for his role in the discovery of the structure of DNA is going on the auction block. The auctioneer says the gold medal could bring $2.5 to $3.5 million on Dec. 4. Christie's says it's the first Nobel medal to be offered at auction by a living recipient. Watson made the 1953 discovery with Francis Crick and Maurice Wilkins.

How turkeys may be lifesavers

November 25, 2014 4:51 pm | by Todd Hollingshead, Brigham Young Univ. | Comments

While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day. That’s because the biological machinery needed to produce a potentially life-saving antibiotic is found in turkeys. Looks like there is one more reason to be grateful this Thanksgiving.

Material snaps together like Legos

November 25, 2014 4:45 pm | by Brendan M. Lynch, KU News Service | Comments

Physicists at the Univ. of Kansas have fabricated an innovative substance from two different atomic sheets that interlock much like Lego toy bricks. The researchers said the new material, made of a layer of graphene and a layer of tungsten disulfide, could be used in solar cells and flexible electronics.

Doctor behind "free radical" aging theory dies

November 25, 2014 2:02 pm | by By Josh Funk - Associated Press - Associated Press | Comments

Dr. Denham Harman, a renowned scientist who developed the most widely accepted theory on aging that's now used to study cancer, Alzheimer's disease and other illnesses, has died in Nebraska at age 98. Harman, who worked into his mid-90s at the Univ. of Nebraska Medical Center died after a brief illness at a hospital in Omaha.

Environmental “tipping points” key to predicting extinctions

November 25, 2014 11:35 am | by Tracey Peake, North Carolina State Univ. | Comments

Researchers from North Carolina State Univ. have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population’s adaptive strategy, even tiny changes in climate variability can create a “tipping point” that sends the population into extinction.

Breakthrough in flexible electronics enabled by inorganic-based laser lift-off

November 25, 2014 11:20 am | by The Korea Advanced Institute of Science and Technology (KAIST) | Comments

Flexible electronics have been touted as the next generation in electronics in various areas, ranging from consumer electronics to bio-integrated medical devices. In spite of their merits, insufficient performance of organic materials arising from inherent material properties and processing limitations in scalability have posed big challenges to developing all-in-one flexible electronics systems.

Researchers develop efficient method to produce nanoporous metals

November 25, 2014 10:42 am | by Kenneth Ma, LLNL | Comments

Nanoporous metals have a wide range of applications because of their superior qualities. They posses a high surface area for better electron transfer, which can lead to the improved performance of an electrode in an electric double capacitor or battery. Nanoporous metals offer an increased number of available sites for the adsorption of analytes, a highly desirable feature for sensors.

Angiogenesis drug could provide treatment for TB

November 25, 2014 9:27 am | by Karl Bates, Duke Univ. | Comments

The body responds to tuberculosis infection by locking the bacterial offenders into tiny clusters of immune cells called granulomas, which are a hallmark of the disease. This containment strategy succeeds at first, but eventually the bacteria manage to break out of these intercellular jails and spread throughout the body.

Pain in a dish

November 25, 2014 9:11 am | by Harvard Stem Cell Institute | Comments

After more than six years of intensive effort, and repeated failures that made the quest at times seem futile, Harvard Stem Cell Institute researchers at Boston Children’s Hospital and Harvard’s Dept. of Stem Cell and Regenerative Biology have successfully converted mouse and human skin cells into pain-sensing neurons that respond to a number of stimuli that cause acute and inflammatory pain.

Wireless electronic implants stop staph

November 25, 2014 8:41 am | by Kim Thurier, Tufts Univ. | Comments

Researchers at Tufts Univ., in collaboration with a team at the Univ. of Illinois at Urbana-Champaign, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering heat to infected tissue when triggered by a remote wireless signal. The silk and magnesium devices then harmlessly dissolved in the test animals. The technique had previously been demonstrated only in vitro.

LLNL, RAND partner to advance policy analysis through supercomputing

November 25, 2014 8:15 am | by Anne M. Stark, Lawrence Livermore National Laboraotry | Comments

Lawrence Livermore National Laboratory and the RAND Corporation will collaborate to expand the use of high-performance computing in decision analysis and policymaking. The two organizations signed a memorandum of understanding on Friday, Nov. 21. The arrangement provides a vehicle for the two organizations to explore the use of policy analysis methodologies with supercomputing applications.

Device could make large biological circuits practical

November 25, 2014 7:59 am | by David L. Chandler, MIT News Office | Comments

Researchers have made great progress in recent years in the design and creation of biological circuits: systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.

Improving technology used in digital memory

November 25, 2014 7:48 am | by Scott Schrage, University Communications, Univ. of Nebraska-Lincoln | Comments

The improvements in random access memory (RAM) that have driven many advances of the digital age owe much to the innovative application of physics and chemistry at the atomic scale. Accordingly, a team led by Univ. of Nebraska-Lincoln researchers has employed a Nobel Prize-winning material and common household chemical to enhance the properties of a component primed for the next generation of high-speed, high-capacity RAM.

Brain’s reaction to virtual reality

November 25, 2014 7:42 am | by Stuart Wolpert, Univ. of California, Los Angeles | Comments

Univ. of California, Los Angeles neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes.
