Unlocking the key to immunological memory in bacteria

March 2, 2015 11:41 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | Comments

A powerful genome editing tool may soon become even more powerful. Researchers with the Lawrence Berkeley National Laboratory have unlocked the key to how bacteria are able to “steal” genetic information from viruses and other foreign invaders for use in their own immunological memory system.

Forbidden quantum leaps possible with high-res spectroscopy

March 2, 2015 11:27 am | by Nicole Casal Moore, Univ. of Michigan | Comments

A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible. Physicists at the Univ. of Michigan have demonstrated "ponderomotive spectroscopy," an advanced form of a technique that was born in the 15th century when Isaac Newton first showed that white light sent through a prism breaks into a rainbow.

Analysis shows ion slowdown in fuel cell material

March 2, 2015 11:01 am | by David L. Chandler, MIT News Office | Comments

Dislocations in oxides such as cerium dioxide, a solid electrolyte for fuel cells, turn out to have a property that is the opposite of what researchers had expected, according to a new analysis. Researchers had thought that a certain kind of strain would speed the transport of oxygen ions through the material, potentially leading to the much faster diffusion that is necessary in high-performance solid-oxide fuel cells.

How to best harness solar power

March 2, 2015 10:48 am | by Dawn Fuller, Univ. of Cincinnati | Comments

A research partnership is reporting advances on how to make solar cells stronger, lighter, more flexible and less expensive when compared with the current silicon or germanium technology on the market. The researchers discovered how a blend of conjugated polymers resulted in structural and electronic changes that increased efficiency three-fold, by incorporating graphene in the active layer of the carbon-based materials.

Supersonic electrons could produce future solar fuel

March 2, 2015 10:38 am | by Lund Univ. | Comments

Researchers from institutions including Lund Univ. have taken a step closer to producing solar fuel using artificial photosynthesis. In a new study, they have successfully tracked the electrons' rapid transit through a light-converting molecule. The ultimate aim of the present study is to find a way to make fuel from water using sunlight.

Neurons controlling appetite made from skin cells

March 2, 2015 9:09 am | by Karin Eskenazi, Columbia Univ. Medical Center | Comments

Researchers have, for the first time, successfully converted adult human skin cells into neurons of the type that regulate appetite, providing a patient-specific model for studying the neurophysiology of weight control and testing new therapies for obesity. To make the neurons, human skin cells were first genetically reprogrammed to become induced pluripotent stem (iPS) cells.

Genetics reveals where emperor penguins survived the last ice age

March 2, 2015 9:00 am | by Univ. of Southampton | Comments

A study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica was likely the refuge for one of these populations.

High-precision radar for the steel industry

March 2, 2015 8:42 am | by Fraunhofer-Gesellschaft | Comments

Steel is the most important material in vehicle and machinery construction. Large quantities of offcuts and scraps are left over from rolling and milling crude steel into strip steel. New radar from Fraunhofer researchers measures the width of the strip during fabrication to an accuracy of micrometers and helps to minimize scrap.

Life “not as we know it” possible on Saturn’s moon Titan

March 2, 2015 8:26 am | by Syl Kacapyr, Cornell Univ. | Comments

A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell Univ. researchers. Taking a simultaneously imaginative and rigidly scientific view, chemical engineers and astronomers offer a template for life that could thrive in a harsh, cold world: specifically Titan, the giant moon of Saturn.

Innovative wireless sensor technology yields better energy efficiency

March 2, 2015 8:17 am | by Sara Shoemaker, Oak Ridge National Laboratory | Comments

Regulating comfort in small commercial buildings could become more efficient and less expensive thanks to an innovative low-cost wireless sensor technology being developed by researchers at Oak Ridge National Laboratory. Buildings are responsible for about 40% of the energy consumed in the U.S. Studies indicate that advanced sensors and controls have the potential to reduce the energy consumption of buildings by 20 to 30%.

First detailed microscopy evidence of bacteria at the lower size limit of life

March 2, 2015 8:08 am | by Dan Krotz, Lawrence Berkeley National Laboratory | Comments

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn’t been a comprehensive electron microscopy and DNA-based description of the microbes until now.

Aerogel catalyst shows promise for fuel cells

March 2, 2015 7:54 am | by Mike Williams, Rice Univ. | Comments

Graphene nanoribbons formed into a 3-D aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells, even in comparison to platinum, according to Rice Univ. researchers. A team led by materials scientist Pulickel Ajayan and chemist James Tour made metal-free aerogels from graphene nanoribbons and various levels of boron and nitrogen to test their electrochemical properties.

Moving molecule writes letters

February 27, 2015 11:55 am | by Andreas Battenberg, TUM | Comments

On the search for high-performance materials for applications such as gas storage, thermal insulators or dynamic nanosystems it’s essential to understand the thermal behavior of matter down to the molecular level. Classical thermodynamics average over time and over a large number of molecules. Within a 3-D space single molecules can adopt an almost infinite number of states, making the assessment of individual species nearly impossible.

Untangling DNA with a droplet of water, pipet and polymer

February 27, 2015 11:42 am | by KU Leuven | Comments

Researchers have long sought an efficient way to untangle DNA in order to study its structure under a microscope. Now, chemists and engineers at KU Leuven have devised a strikingly simple and effective solution: They inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.

Sun has more impact on climate in cool periods

February 27, 2015 10:24 am | by Aarhus Univ. | Comments

The activity of the sun is an important factor in the complex interaction that controls our climate. New research now shows the impact of the sun isn’t constant over time, but has greater significance when the Earth is cooler. There has been much discussion as to whether variations in the strength of the sun have played a role in triggering climate change in the past.
