June 12, 2014 8:17 am | News | Comments

An international team of scientists, led by researchers at the Univ. of California, San Diego School of Medicine, have identified the genes encoding a molecule that famously defines Group A Streptococcus (strep), a pathogenic bacterial species responsible for more than 700 million infections worldwide each year.

Mining data archives yields haul of “red nuggets”

June 12, 2014 8:09 am | by David A. Aguilar, Harvard-Smithsonian Center for Astrophysics | News | Comments

The world of astronomy has changed. An astronomer used to have to travel to a remote location and endure long, cold nights, patiently guiding a telescope to collect precious photons of light. Now, a proliferation of online archives allows astronomers to make discoveries from the comfort of their own offices.

Their report on a new solid, stable material that can pack in a large amount of hydrogen that can be used as a fuel appears in Chemistry of Materials.

DNA-lined nanoparticles form switchable thin films on liquid surface

June 11, 2014 8:22 am | by Karen McNulty Walsh, Brookhaven National Laboratory | News | Comments

Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first: the formation of a single layer of nanoparticles on a liquid surface where the properties of the layer can be easily switched. Understanding the assembly of such nanostructured thin films could lead to the design of new kinds of membranes with a variable mechanical response for a wide range of applications.

Research develops “onion” vesicles for drug delivery

June 10, 2014 11:22 am | by Evan Lerner, Univ. of Pennsylvania | News | Comments

One of the defining features of cells is their membranes. Each cell’s repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane structures, known as vesicles, still face many problems when made in the laboratory.

Researchers create nanoparticle thin films that self-assemble in one minute

June 10, 2014 7:51 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with Lawrence Berkeley National Laboratory have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.

R&D Scene: 3-D Printing Ushers In New Era of Manufacturing

June 9, 2014 1:42 pm | by Lindsay Hock, Managing Editor | Videos | Comments

Thirty years have passed since 3-D printers first appeared, but only recently have they hinted at a new era of manufacturing. The first working 3-D printer was created in 1984 by Chuck Hull of 3D Systems Corp. This early device, based on stereolithography, gave way to the first truly practical 3-D printing technology patented by the Massachusetts Institute of Technology in 1993.

Bringing new life to Laser Guide Star

June 9, 2014 10:54 am | by Breanna Bishop, Lawrence Livermore National Laboratory | News | Comments

Earlier this year, Lawrence Livermore National Laboratory engineering technical associate Pam Danforth applied 30 years of laser experience to an out-of-this-world problem—bringing new life to the Univ. of California's Lick Observatory Laser Guide Star. The Lick Observatory's Laser Guide Star is vital to astronomers because a natural guide star isn't always near an object they want to observe.

Scientists reveal details of calcium “safety valve” in cells

June 9, 2014 8:18 am | by Karen McNulty Walsh, Brookhaven National Laboratory | News | Comments

Sometimes a cell has to die—when it's done with its job or inflicted with injury that could otherwise harm an organism. Conversely, cells that refuse to die when expected can lead to cancer. So scientists interested in fighting cancer have been keenly interested in learning the details of "programmed cell death." They want to understand what happens when this process goes awry and identify new targets for anticancer drugs.

Better tissue healing with disappearing hydrogels

June 9, 2014 8:06 am | by Peter Iglinski, Univ. of Rochester | News | Comments

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a Univ. of Rochester research team keeps the stem cells in place, resulting in faster and better tissue regeneration. The keyis encasing the stem cells in polymers that attract water and disappear when their work is done.

Evolution of a bimetallic nanocatalyst

June 9, 2014 7:58 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal or plant biomass. A multinational laboratory collaboration has taken the most detailed look ever at the evolution of platinum/cobalt bimetallic nanoparticles during reactions in oxygen and hydrogen gases.

June 9, 2014 7:44 am | by David L. Chandler, MIT News Office | News | Comments

New observations by researchers at Massachusetts Institute of Technology have revealed the inner workings of a type of electrode widely used in lithium-ion batteries. The new findings explain the unexpectedly high power and long cycle life of such batteries, the researchers say.

Short nanotubes target pancreatic cancer

June 6, 2014 10:45 am | by Mike Williams, Rice Univ. | News | Comments

Short, customized carbon nanotubes have the potential to deliver drugs to pancreatic cancer cells and destroy them from within, according to researchers at Rice Univ. and the Univ. of Texas MD Anderson Cancer Center. Pristine nanotubes produced through a new process developed at Rice can be modified to carry drugs to tumors through gaps in blood-vessel walls that larger particles cannot fit through.

Ionic liquid boosts efficiency of carbon dioxide reduction catalyst

June 6, 2014 7:50 am | by Karen McNulty Walsh, Brookhaven National Laboratory | News | Comments

Wouldn’t it be nice to use solar- or wind-generated electricity to turn excess carbon dioxide into fuels and other useful chemicals? The process would store up the intermittent solar or wind energy in a form that could be used when and where it was needed, including in transportation applications, all while getting rid of some greenhouse gas.

Engineers develop mobile DNA test for HIV

June 6, 2014 7:31 am | by Mike Williams, Rice Univ. | News | Comments

Rice Univ. bioengineers are developing a simple, highly accurate test to detect signs of HIV and its progress in patients in resource-poor settings. The current gold standard to diagnose HIV in infants and to monitor viral load depends on laboratory equipment and technical expertise generally available only in clinics. The new research features a nucleic acid-based test that can be performed at the site of care.

Sustainable Laboratory Design and Construction: Control and Monitoring

June 5, 2014 9:53 am | by Tim Studt | Siemens Industry, Inc. | Articles | Comments

Taking a cue from basic management practices, the adage that you can’t control or manage what you don’t measure or monitor is just as true in sustainability applications as it is in human relations. All the design efforts created by the architects and engineers for a sustainable research lab structure can be wasted if monitoring and control systems aren’t put in place.
