Ebola fear, monitoring eases for some in Dallas

October 20, 2014 1:26 am | by Marilynn Marchione - Associated Press - Associated Press | News | Comments

Ebola fears began to ease for some Monday as a monitoring period passed for those who had close contact with a victim of the disease and after a cruise ship scare ended with the boat returning to port and a laboratory worker on board testing negative for the virus. Federal officials meanwhile ramped up readiness to deal with future cases.

Software for Super-resolution Microscopy

October 17, 2014 2:01 pm | Product Releases | Comments

Researchers using microscopy for cell and tissue imaging can now obtain optical resolution of up to 120 nm, thanks to a novel software upgrade from Olympus. With Olympus FV-OSR software, the FluoView FV1200 confocal laser scanning microscope is transformed into a powerful system for super-resolution microscopy.

Rotary Encoder

October 17, 2014 1:58 pm | Product Releases | Comments

The Leine & Linde MRI 2000 rotary encoder is designed to provide feedback solutions for large rotating machinery, Introduced two years ago, this encoder has now received significant performance upgrades. The MRI ring encoder is segmented into pieces, something that facilitates simple commissioning and service and is of particular benefit on large rotating machinery.

A new material brings spintronics closer

October 17, 2014 1:45 pm | News | Comments

Spintronics is a new field of electronics, using electron spin rather than charge. Researchers have discovered that a common insulating material behaves as a perfect spintronic conductor because it is not affected by background electron charge. In addition, the material’s properties make it an ideal platform for directly observing a strange subatomic particle that could one day lead to a different, more stable type of quantum computers.

Geneticists evaluate cost-effective genome analysis

October 17, 2014 1:39 pm | News | Comments

Scientists perform genome sequences because want to know why individuals differ from each other and how these differences are encoded in the DNA. However, sequencing a complete genome still costs around $1,000, and sequencing hundreds of individuals would be costly. In two recent review papers, scientists discuss why DNA sequencing of entire groups, or pool sequencing, can be an efficient and cost-effective approach.

The Jefferson Project at Lake George unveils state-of-the-art data visualization laboratory

October 17, 2014 11:47 am | Videos | Comments

A partnership between Rensselaer Polytechnic Institute, IBM, and the FUND for Lake George has developed preliminary models of key natural processes within the watershed. A network of 12 sensor platforms including vertical profilers and tributary monitoring stations are now being deployed in Lake George and its tributaries, providing an unprecedented amount of data for researchers that will be interpreted at a new visualization laboratory.

Designing antibiotics of the future

October 17, 2014 9:48 am | News | Comments

Scientists have used computer simulations to show how bacteria are able to destroy antibiotics, a breakthrough which will help develop drugs which can effectively tackle infections in the future. Researchers at the Univ. of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it working, making the bacteria resistant.

New catalyst could improve biofuels production

October 17, 2014 9:36 am | by Tina Hilding, Voiland College of Engineering & Architecture | News | Comments

Washington State Univ. (WSU) researchers have developed a new catalyst that could lead to making biofuels cheaply and more efficiently. The WSU researchers developed a mixture of two metals, iron along with a tiny amount of palladium, to serve as a catalyst to efficiently and cheaply remove oxygen.

Scientists discover carbonate rocks are unrecognized methane sink

October 17, 2014 9:25 am | by Mark Floyd, Oregon State Univ. | News | Comments

Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane as part of understanding how the Earth works. The sediment-based microbes form an important methane “sink,” preventing much of the chemical from reaching the atmosphere and contributing to greenhouse gas accumulation.

Scientist invent new method for fabricating graphene nanoribbons

October 17, 2014 9:23 am | by Shaun Mason, UCLA | News | Comments

Graphene’s exotic properties can be tailored by cutting large sheets down to ribbons of specific lengths and edge configurations. But this “top-down” fabrication approach is not yet practical, because current lithographic techniques always produce defects. Now, scientists from the U.S. and Japan have discovered a new “bottom-up” self-assembly method for producing defect-free graphene nanoribbons with periodic zigzag-edge regions.

Sound-powered chip to serve as medical device

October 17, 2014 9:18 am | by Tom Abate, Stanford Engineering | News | Comments

Medical researchers would like to plant tiny electronic devices deep inside our bodies to monitor biological processes and deliver pinpoint therapies to treat illness or relieve pain. But so far engineers have been unable to make such devices small and useful enough. Providing electric power to medical implants has been one stumbling block. Using wires or batteries to deliver power tends to make implants too big, too clumsy—or both.

ORNL joins global fight against polio

October 17, 2014 8:36 am | by Christopher R. Samoray, Oak Ridge National Laboratory | News | Comments

The new Urban Dynamics Institute at Oak Ridge National Laboratory is working with the Bill & Melinda Gates Foundation to aid polio vaccination efforts in developing countries. Teams at the institute will apply big data analysis to population dynamics in Nigeria, allowing polio vaccination crews to better estimate the amount of vaccine needed and to target areas of priority, saving time and money in eradicating the disease.

LLNL, UC Davis partner to personalize cancer medications

October 17, 2014 8:27 am | by Stephen P Wampler, Lawrence Livermore National Laboratory | News | Comments

Buoyed by several dramatic advances, Lawrence Livermore National Laboratory (LLNL) scientists think they can tackle biological science in a way that couldn't be done before. Over the past two years, LLNL researchers have expedited accelerator mass spectrometer sample preparation and analysis time from days to minutes and moved a complex scientific process requiring accelerator physicists into routine laboratory usage.

What gives the sun its heat

October 17, 2014 8:01 am | by David A. Aguilar, Harvard-Smithsonian Center for Astrophysics | News | Comments

Why is the sun's million-degree corona, or outermost atmosphere, so much hotter than the sun's surface? This question has baffled astronomers for decades. A team led by the Harvard-Smithsonian Center for Astrophysics is presenting new clues to the mystery of coronal heating using observations from the recently launched Interface Region Imaging Spectrograph (IRIS).

Dispelling a misconception about Mg-ion batteries

October 17, 2014 8:01 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Lithium-ion batteries are popular, but have limitations in energy density, lifetime and safety. One alternative is Mg-ion batteries. Researchers at Lawrence Berkeley National Laboratory ran a series of computer simulations that suggest that performance bottlenecks experienced with Mg-ion batteries to date may not be so much related to the electrolyte itself, but to what happens at the interface between the electrolyte and electrodes.
