Platinum meets its match in quantum dots from coal

October 1, 2014 | by Mike Williams, Rice Univ. | Comments

Graphene quantum dots created at Rice Univ. grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.

Ultrafast remote switching of light emission

October 1, 2014 9:15 am | Comments

Researchers in the Netherlands can now, for the first time, remotely control a miniature light source at timescales of 200 trillionths of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.

Virtual breast could improve cancer detection

October 1, 2014 9:10 am | by Marcia Goodrich, Michigan Technological Univ. | Comments

Only a minority of suspicious mammograms actually leads to a cancer diagnosis, which results in lots of needless worry and spent time for women and their families. Ultrasound elastography could be an excellent screening tool but it requires a lot of skill and interpretation. In an effort to improve results, researchers in Michigan have developed a virtual “breast”, allowing medical professionals to practice in the laboratory.

Government confirms first case of Ebola in U.S.

September 30, 2014 7:38 pm | by David Warren - Associated Press - Associated Press | Comments

Federal health officials on Tuesday confirmed the first case of Ebola diagnosed in the U.S., a patient who recently traveled from Liberia to Dallas and a sign of the far-reaching impact of the out-of-control epidemic in West Africa. The unidentified patient was critically ill and has been in isolation at Texas Health Presbyterian Hospital since Sunday, officials said.

A new dimension for integrated circuits: 3-D nanomagnetic logic

September 30, 2014 1:39 pm | Comments

Electrical engineers in Germany have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on 3-D arrangements of nanometer-scale magnets instead of transistors. In a 3-D stack of nanomagnets, the researchers have implemented a so-called “majority” logic gate, which could serve as a programmable switch in a digital circuit.

Adding natural uncertainty improves mathematical models

September 30, 2014 1:11 pm | Comments

Mathematicians from Brown Univ. have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. Ironically, allowing uncertainty into a mathematical equation that models fluid flows makes the equation much more capable of correctly reflecting the natural world, including the formation, strength, and position of air masses and fronts in the atmosphere.

New discovery approach accelerates identification of potential cancer treatments

September 30, 2014 9:50 am | by Laura Williams, Univ. of Michigan | Comments

Researchers at the Univ. of Michigan have described a new approach to discovering potential cancer treatments that requires a fraction of the time needed for more traditional methods. They used the platform to identify a novel antibody that is undergoing further investigation as a potential treatment for breast, ovarian and other cancers.

Glaciers in the Grand Canyon of Mars?

September 30, 2014 8:56 am | Comments

For decades, planetary geologists have speculated that glaciers might once have crept through Valles Marineris, the 2000-mile-long chasm that constitutes the Grand Canyon of Mars. A research team has now identified what could be the first mineralogical evidence of past glaciers within the Valles Marineris: a layer of mixed sulfate minerals halfway up three-mile-high cliffs in the canyon system.

Research suggests new strategies for fighting TB

September 30, 2014 8:22 am | by Kevin Stacey, Brown Univ. | Comments

Over the past few years, a class of compounds called ADEPs (cyclic acyldepsipeptides) has emerged as a promising new weapon in the fight against drug-resistant bacteria. The compounds work by attaching themselves to a cellular enzyme called ClpP, which bacterial cells use to rid themselves of harmful proteins. With an ADEP attached, ClpP can’t function properly, and the bacterial cell dies.

Wildlife populations plummet for 3,000 species

September 30, 2014 8:19 am | by John Heilprin, Associated Press | Comments

About 3,000 species of wildlife around the world have seen their numbers plummet far worse than previously thought, according to a new study by one of the world's biggest environmental groups. The Switzerland-based WWF says improved methods of measuring populations of fish, birds, mammals, amphibians and reptiles explain the huge difference from the 28% decline between 1970 and 2008 that the group reported in 2012.

At the interface of math and science

September 30, 2014 8:09 am | by Julie Cohen, UC Santa Barbara | Comments

Univ. of California, Santa Barbara’s Paul Atzberger, a professor in the Department of Mathematics and in mechanical engineering, often works in areas where mathematics plays an ever more important role in the discovery and development of new ideas. Most recently he has developed new mathematical approaches to gain insights into how proteins move around within lipid bilayer membranes.

Automated sorting through metagenomes

September 30, 2014 8:05 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | Comments

Microbes have an amazing ability to feed on plant biomass and convert it into other chemical products. Tapping into this talent has the potential to revolutionize energy, medicine, environmental remediation and many other fields. The success of this effort hinges in part on metagenomics, the emerging technology that enables researchers to read all the individual genomes of a sample microbial community at once.

Researchers develop transparent nanoscintillators for radiation detection

September 30, 2014 7:56 am | by Traci Peterson, Univ. of Texas at Arlington | Comments

A Univ. of Texas at Arlington research team says recently identified radiation detection properties of a light-emitting nanostructure built in their lab could open doors for homeland security and medical advances. In a paper to be published in Optics Letters, the team describes a new method to fabricate transparent nanoscintillators by heating nanoparticles composed of lanthanum, yttrium and oxygen until a transparent ceramic is formed.

Fat molecules influence form, function of key photosynthesis protein

September 30, 2014 7:48 am | by Elizabeth K. Gardner, Purdue Univ. | Comments

A mysterious space within a protein critical to photosynthesis is filled with fat molecules that influence both the protein’s architecture and electrical properties, according to two recent studies. Researchers studied the atomic structure of, and electrical interactions within, the cytochrome bf complex, a protein complex central to the transport of electrons within membranes of a plant cell, a critical step in photosynthesis.
