Shaping the future of nanocrystals

August 22, 2014 8:55 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | Videos | Comments

The first direct observations of how facets form and develop on platinum nanocubes point the way towards more sophisticated and effective nanocrystal design and reveal that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

Sunblock poses potential hazard to sea life

August 22, 2014 8:24 am | by American Chemical Society | News | Comments

The sweet and salty aroma of sunscreen and seawater signals a relaxing trip to the shore. But scientists are now reporting that the idyllic beach vacation comes with an environmental hitch. When certain sunblock ingredients wash off skin and into the sea, they can become toxic to some of the ocean’s tiniest inhabitants, which are the main course for many other marine animals.

Electric sparks may alter evolution of lunar soil

August 22, 2014 8:18 am | by David Sims, Institute for the Study of Earth, Oceans and Space, Univ. of New Hampshire | News | Comments

The moon appears to be a tranquil place, but modeling done by Univ. of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon’s coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system.

Laser device may end pin pricks for diabetics

August 22, 2014 8:07 am | by John Sullivan, Office of Engineering Communications, Princeton Univ. | News | Comments

Princeton Univ. researchers have developed a way to use a laser to measure people's blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood.

Clues uncovered to role of magnetism in iron-based superconductors

August 22, 2014 7:57 am | by Morgan McCorkle, Oak Ridge National Laboratory | News | Comments

New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at Oak Ridge National Laboratory and Vanderbilt Univ. are challenging conventional wisdom about superconductivity and magnetism. The study provides experimental evidence that local magnetic fluctuations can influence the performance of iron-based superconductors, which transmit electric current without resistance at relatively high temperatures.

Researchers map quantum vortices inside superfluid helium nanodroplets

August 22, 2014 7:41 am | by Kate Greene, Lawrence Berkeley National Laboratory | News | Comments

Scientists have, for the first time, characterized so-called quantum vortices that swirl within tiny droplets of liquid helium. The research, led by scientists at Lawrence Berkeley National Laboratory, the Univ. of Southern California and SLAC National Accelerator Laboratory, confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues for studying quantum rotation.

Scientists develop water splitter that runs on ordinary AAA battery

August 22, 2014 7:27 am | by Mark Shwartz, Stanford Univ. | Videos | Comments

In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming. Now scientists at Stanford Univ. have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.

American Ebola doctor urges help fighting outbreak

August 22, 2014 4:25 am | by Kathleen Foody - Associated Press - Associated Press | News | Comments

As one of few Ebola survivors with medical expertise, Dr. Kent Brantly seems keenly aware of the position his painful experience has put him in. He hasn't spoken yet about his plans, but spent much of his first public appearance pleading for help for countries still struggling with the virus.

A Smart Solution to RNA Detection

August 21, 2014 4:37 pm | Award Winners

RNA detection traditionally requires transfection, laborious sample prep, RNA amplification and/or detection based on standard curves. In contrast, EMD Millipore’s SmartFlare RNA Detection Probes are endocytosed by live cells using existing cellular endocytosis machinery. Sample prep is unnecessary.

TB Be Gone

August 21, 2014 4:27 pm | Award Winners

MDR-TB is a growing problem, estimated to kill 170,000 people annually and projected to infect more than two million people between 2011 and 2015. Janssen Research & Development LLC’s bedaquiline represents a significant scientific and public health advancement in the treatment of MDR-TB, as the first available medicine developed specifically for pulmonary MDR-TB treatment.

Saving Childrens’ Lives

August 21, 2014 4:18 pm | Award Winners

Globally, 22 million infants aren’t receiving basic vaccines and 1.5 million children will die each year from vaccine-preventable diseases before they reach age five. This challenge is further complicated by the fact that most vaccines must be refrigerated, and more than a billion people globally don’t have reliable access to electricity. Vaccination rates are lowest in remote and rural locations. As part of Intellectual Ventures’ Global Good program, Intellectual Venture Labs (IVL) approached Stratos Product Development for help in developing an insulated container to strengthen and extend vaccination services in developing countries.

Microarray for Complex Chemotyping

August 21, 2014 4:05 pm | Award Winners

Whether the application is biofuels, microbial ecological investigation or medical research, Lawrence Berkeley National Laboratory’s Berkeley Lab Multiplex Chemotyping Microarray (MCM) has proven to be the most powerful and precise system for investigations of biomass at the molecular level. MCM performs rapid chemical analyses of prospective biofuel crops and microbial communities by combining high-throughput micro-contact printing technology with high-fidelity vibrational spectroscopy and mass spectrometry.

Novilytic’s Noviplex Plasma Collection Card is a self-contained, blood-plasma sampling device used to volumetrically collect a plasma aliquot independent of whole blood application volumes. The Noviplex requires no power and circumvents requirements for venipuncture-phlebotomy training, needles, special vials and equipment, refrigeration and centrifugation normally associated with traditional plasma methods.

Powerful Single-output Laser

August 21, 2014 3:36 pm | Award Winners

Spectral beam combining (SBC) of fiber lasers offers a straightforward approach for power scaling. The approach exploits the broad gain bandwidth to enable large numbers of fiber laser channels to be combined with near-diffraction-limited beam quality. Rigorous application of SBC has allowed a development team including Lawrence Livermore National Laboratory, Lockheed Martin Laser and Sensor Systems and Advanced Thin Films to develop the EXtreme-power, Ultra-low-loss, Dispersive Element (EXUDE) optical element, the first-ever electrically efficient, near diffraction-limited 30-kW beam combined laser.
