Is the U.S. doing enough to fight Ebola?

September 16, 2014 11:46 am | by Lauran Neergaard, The Associated Press | News | Comments

The American strategy on Ebola is two-pronged: step up desperately needed aid to West Africa and, in an unusual step, train U.S. doctors and nurses for volunteer duty in the outbreak zone. At home, the goal is to speed up medical research and put hospitals on alert should an infected traveler arrive.

Researchers control surface tension to manipulate liquid metals

September 16, 2014 9:40 am | by Matt Shipman, News Services, North Carolina State Univ. | Videos | Comments

Researchers from North Carolina State Univ. have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies. The technique hinges on the fact that the oxide “skin” of the metal acts as a surfactant, lowering the surface tension between the metal and the surrounding fluid.

EEG study findings reveal how fear is processed in the brain

September 16, 2014 8:51 am | News | Comments

Building on previous animal and human research, a new study has identified an electrophysiological marker for threat in the brain. The findings illustrate how fear arises in the brain when individuals are exposed to threatening images, and the study is the first to separate emotion from threat by controlling for the dimension of arousal, the emotional reaction provoked, whether positive or negative, in response to stimuli.

Elusive quantum transformations found near absolute zero

September 16, 2014 8:13 am | by Justin Eure, Brookhaven National Laboratory | News | Comments

Heat drives classical phase transitions, but much stranger things can happen when the temperature drops. If phase transitions occur at the coldest temperatures imaginable, where quantum mechanics reigns, subtle fluctuations can dramatically transform a material. Scientists have explored this frigid landscape of absolute zero to isolate and probe these quantum phase transitions with unprecedented precision.

Early Earth less hellish than previously thought

September 16, 2014 7:53 am | by David Salisbury, Vanderbilt Univ. | News | Comments

Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate view of Earth’s first geologic eon, called the Hadean, has gained substantial new support from the first detailed comparison of zircon crystals that formed more than 4 billion years ago with those formed contemporaneously in Iceland.

Muscular dystrophy: Repair the muscles, not the genetic defect

September 16, 2014 7:52 am | by Laura Bailey, Univ. of Michigan | News | Comments

A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease. Muscular dystrophies are a group of muscle diseases characterized by skeletal muscle wasting and weakness. Mutations in certain proteins, most commonly the protein dystrophin, cause muscular dystrophy in humans and also in mice.

“Squid skin” metamaterials project yields vivid color display

September 16, 2014 7:41 am | by Jade Boyd, Rice Univ. | News | Comments

The quest to create artificial “squid skin”—camouflaging metamaterials that can “see” colors and automatically blend into the background—is one step closer to reality, thanks to a breakthrough color-display technology unveiled by Rice Univ. The new full-color display technology uses aluminum nanoparticles to create the vivid red, blue and green hues found in today’s top-of-the-line LCD televisions and monitors.

Study: Number-crunching could lead to unethical choices

September 15, 2014 5:02 pm | News | Comments

Calculating the pros and cons of a potential decision is a way of decision-making. But repeated engagement with numbers-focused calculations, especially those involving money, can have unintended negative consequences, including social and moral transgressions, says new study. Several experiments supported these findings and pointed to a “calculative mindset” that can take precedence in reaching conclusions.

NASA inspector blasts asteroid protection program

September 15, 2014 4:58 pm | by Marcia Dunn, AP Aerospace Writer | News | Comments

On Monday, NASA's inspector general released a report blasting the agency’s Near Earth Objects program, which is meant to hunt and catalog comets, asteroids and relatively large fragments of these objects that pass within 28 million miles of Earth. The purpose is to protect the planet against their potential dangers, but only 10% of the near-Earth objects bigger than 460 ft across have been catalogued, well short of the goal of 90% by 2020.

The shadow of a disease

September 15, 2014 8:45 am | News | Comments

Researchers have developed an optical method that makes individual proteins, such as the proteins characteristic of some cancers, visible. Other methods that achieve this only work if the target biomolecules have first been labeled with fluorescent tags, but this approach is very difficult. By contrast, the new method allows scientists to directly detect the scattered light of individual proteins via their shadows.
