Heat blamed for spray vaccine's failure against swine flu

February 26, 2015 1:10 pm | by Mike Stobbe, AP Medical Writer, Associated Press | News | Comments

The makers of the nasal spray version of the flu vaccine say they now know why it didn't protect young children against swine flu—the doses got too warm. The spray FluMist works well for most flu strains, but small studies found it didn't work very well against the swine flu bug that first emerged in 2009.

Study maps extroversion types in brain’s anatomy

February 26, 2015 12:43 pm | by David Orenstein, Brown Univ. | News | Comments

Everyday experience and psychological studies alike tell us there are two different types of extroverts: The gregarious “people-persons” and the ambitious “go-getters”. A new study shows that these overlapping yet distinct personalities have commensurately overlapping yet distinct signatures in the anatomy of the brain.

Research predicts when, how materials will act

February 26, 2015 12:09 pm | by Kathleen Haughney, Florida State Univ. | News | Comments

In science, it’s commonly known that materials can change in a number of ways when subjected to different temperatures, pressures or other environmental forces.  A material might melt or snap in half. And for engineers, knowing when and why that might happen is crucial information.  Now, a Florida State Univ. researcher has laid out an overarching theory that explains why certain materials act the way they do.

Building blocks of the future defy logic

February 26, 2015 11:58 am | by Cassi Camilleri, Univ. of Malta | News | Comments

Wake up in the morning and stretch; your midsection narrows. Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume that when a force is applied along an axis, materials will always stretch and become thinner. Wrong.

Physicists find new form of quantum friction

February 26, 2015 11:40 am | by Ike Sweitlitz, Yale Univ. | News | Comments

Physicists at Yale Univ. have observed a new form of quantum friction that could serve as a basis for robust information storage in quantum computers in the future. The researchers are building upon decades of research, experimentally demonstrating a procedure theorized nearly 30 years ago.

Using “fuzzy logic” to optimize hybrid solar/battery systems

February 26, 2015 11:11 am | by American Institute of Physics | News | Comments

How did fuzzy logic help a group of researchers in Tunisia and Algeria create an ideal photovoltaic system that obeys the supply-and-demand principle and its delicate balance? In the Journal of Renewable & Sustainable Energy, the group describes a new sizing system of a solar array and a battery in a standalone photovoltaic system that is based on fuzzy logic.

A mollusk of a different stripe

February 26, 2015 10:59 am | by Jennifer Chu, MIT News Office | Videos | Comments

The blue-rayed limpet is a tiny mollusk that lives in kelp beds along the coasts of Norway, Iceland, the U.K., Portugal and the Canary Islands. These diminutive organisms might escape notice entirely, if not for a very conspicuous feature: bright blue dotted lines that run in parallel along the length of their translucent shells. Depending on the angle at which light hits, a limpet’s shell can flash brilliantly even in murky water.

New insight found in black hole collisions

February 26, 2015 10:50 am | by Amanda Siegfried, UT Dallas | News | Comments

New research by a Univ. of Texas, Dallas astrophysicist provides revelations about the most energetic event in the universe: the merging of two spinning, orbiting black holes into a much larger black hole. The work provides, for the first time, solutions to decades-old equations that describe conditions as two black holes in a binary system orbit each other and spiral in toward a collision.

Smartphones could tell consumers what's in food

February 26, 2015 9:09 am | by Mary Clare Jalonick, Associated Press | News | Comments

In the ever-complicated debate over labeling of genetically modified foods, Agriculture Secretary Tom Vilsack says he has an idea: use your smartphone. Vilsack told members of Congress on Wednesday that consumers could just use their phones to scan special bar codes or other symbols on food packages in the grocery store. All sorts of information could pop up, such as whether the food's ingredients include genetically modified organisms.

New technology could make treatment of oil and gas wastewater simpler, cheaper

February 26, 2015 9:05 am | by Univ. of Colorado at Boulder | News | Comments

Oil and gas operations in the U.S. produce about 21 billion barrels of wastewater per year. The saltiness of the water and the organic contaminants it contains have traditionally made treatment difficult and expensive. Engineers at the Univ. of Colorado Boulder have invented a simpler process that can simultaneously remove both salts and organic contaminants from the wastewater, all while producing additional energy.

The body’s transformers

February 26, 2015 8:59 am | by Julie Cohen, UC Santa Barbara | Videos | Comments

Like the shape-shifting robots of "Transformers" fame, a unique class of proteins in the human body also has the ability to alter their configuration. These so-named intrinsically disordered proteins lack a fixed or ordered 3-D structure, which can be influenced by exposure to various chemicals and cellular modifications. A new study looked at a particular IDP called tau, which plays a critical role in human physiology.

Researchers bend highly energetic electron beam with crystal

February 26, 2015 8:39 am | by SLAC National Accelerator Laboratory | News | Comments

An international team of researchers working at SLAC National Accelerator Laboratory has demonstrated that a bent silicon crystal can bend the paths of focused, very energetic electron beams much more than magnets used today. The method could be of interest for particle accelerator applications such as next-generation x-ray lasers that will help scientists unravel atomic structures and motions in unprecedented detail.

X-ray microscope for nanoscale imaging

February 26, 2015 8:29 am | by Chelsea Whyte, Brookhaven National Laboratory | News | Comments

Delivering the capability to image nanostructures and chemical reactions down to nanometer resolution requires a new class of x-ray microscope that can perform precision microscopy experiments using ultra-bright x-rays from the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory.

ORNL, Whirlpool to develop new energy-efficient refrigerator

February 26, 2015 8:20 am | by Morgan McCorkle, Oak Ridge National Laboratory | News | Comments

Oak Ridge National Laboratory and Whirlpool Corp. are collaborating to design a refrigerator that could cut energy use by up to 40% compared with current models. The goal of the CRADA is to make a next-generation household refrigerator more energy efficient by using WISEMOTION, an innovative linear compressor manufactured by Embraco, and other novel technologies and materials.

Carbon dioxide’s increasing greenhouse effect at Earth’s surface

February 26, 2015 8:12 am | by Dan Krotz, Lawrence Berkeley National Laboratory | Videos | Comments

Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. The researchers, led by scientists from Lawrence Berkeley National Laboratory, measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America.
