The Lead

Team is first to capture motion of single molecule in real time

September 16, 2014 | Comments

Chemists at the Univ. of California, Irvine, have scored a scientific first: capturing moving images of a single molecule as it vibrates, or “breathes,” and shifts from one quantum state to another. The groundbreaking achievement, led by Ara Apkarian, professor of chemistry, and Eric Potma, associate professor of chemistry, opens a window into the strange realm of quantum mechanics.

For electronics beyond silicon, a new contender emerges

September 17, 2014 8:13 am | by Caroline Perry, Harvard Univ. | Comments

Silicon has few serious competitors as the material of choice in the electronics industry. Yet transistors can’t simply keep shrinking to meet the needs of powerful, compact devices; physical limitations like energy consumption and heat dissipation are too significant. Now, using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude.

Nanoribbon film keeps glass ice-free

September 17, 2014 7:58 am | by Jade Boyd, Rice Univ. | Comments

Rice Univ. scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work by Rice chemist James Tour and his colleagues could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies (RF).

Novel capability enables first test of real turbine engine conditions

September 17, 2014 7:46 am | by Tona Kunz, Argonne National Laboratory | Comments

Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.

How to hide like an octopus

September 17, 2014 7:33 am | by David L. Chandler, MIT News Office | Comments

Cephalopods are among nature’s most skillful camouflage artists, able to change both the color and texture of their skin within seconds to blend into their surroundings. Engineers have long struggled to duplicate this in synthetic materials. Now a team of researchers has come closer than ever to achieving that goal, creating a flexible material that can change its color or fluorescence and its texture at the same time.

NASA makes selections for astronaut transport to space station

September 16, 2014 6:07 pm | Comments

Groundbreaking contracts worth $6.8 billion were issued Tuesday to Boeing and SpaceX to transport U.S. crews to and from the space station using their CST-100 and Crew Dragon spacecraft, respectively. NASA’s awards to United States spacecraft will meet a goal of ending the nation’s sole reliance on Russia in 2017.

CDC study: Americans' bellies are expanding fast

September 16, 2014 4:37 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | Comments

The number of American men and women with big-bellied, apple-shaped figures—the most dangerous kind of obesity—has climbed at a startling rate over the past decade, according to a government study. People whose fat has settled mostly around their waistlines instead of in their hips, thighs, buttocks or all over are known to run a higher risk of heart disease, diabetes and other obesity-related ailments.

Setting a course for genomic islands

September 16, 2014 11:57 am | by Jim Shelton, Yale Univ. | Comments

Yale Univ. scientists are exploring uncharted genomic islands to study new chemistry between bacteria and their hosts, from invertebrates to humans. One such discovery is published in Chemistry & Biology. The findings describe a biological pathway that contains a hypothetical protein responsible for the formation of a rare, bicyclic sugar.

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

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

Scientists discover RNA modifications in some unexpected places

September 16, 2014 11:40 am | by Matt Fearer, Whitehead Institute | Comments

Deploying sophisticated high-throughput sequencing technology, a team of Whitehead Institute and Broad Institute researchers have collaborated on a comprehensive, high-resolution mapping that confirms a post-transcriptional RNA modification called pseudouridylation does indeed occur naturally in messenger RNA. This is somewhat surprising finding using a new quantitative sequencing method.

EEG study findings reveal how fear is processed in the brain

September 16, 2014 8:51 am | 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 | 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. | 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 | 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. | 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 | 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.
