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.

World's first bullet train, made in Japan, turns 50

October 1, 2014 10:23 am | by Emily Wang and Ken Moritsugu, Associated Press | Comments

It was, retired Japanese railway engineer Fumihiro Araki recalls, "like flying in the sky." Zipping cross-country in a super-high-speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday.

“Smart” bandage emits phosphorescent glow for healing below

October 1, 2014 9:37 am | Comments

Inspired by a desire to help wounded soldiers, an international team has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Because oxygen plays a critical role in healing, mapping these levels in severe wounds and burns can help to greatly improve the success of surgeries to restore limbs and physical functions.

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.

Gene mutation may lead to development of new cancer drugs

October 1, 2014 8:52 am | by Laura Bailey, Univ. of Michigan | Comments

The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the Univ. of Michigan recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can't regenerate and make new blood.

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.

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.
