CO2-neutral hydrogen from biomass
CO2-neutral hydrogen from biomass
Without fossil fuels, there can be no blast furnace process - but hydrogen could play a more important role in the future. An environmentally friendly process is being developed at TU Wien by which biomass can be used to produce a hydrogen-rich gas that can then be employed in various ways in the iron and steel industry.

To connect biology with electronics, be rigid, yet flexible
The problem is a fundamental incompatibility in communication styles. That conclusion might crop up during divorce proceedings, or describe a diplomatic row. But scientists designing polymers that can bridge the biological and electronic divide must also deal with incompatible messaging styles. Electronics rely on racing streams of electrons, but the same is not true for our brains.

Molecular mechanism underlies anxiety, autism
The top image shows the movement of a mouse in a behavioral test that measures social interaction. The blue to green color represents least to most time spent interacting with another mouse. The bottom set of images measures anxiety-like behavior exhibited by a mouse. The amount of filling in the vertical bars represents levels of anxiety.

Pregnancy problems not necessarily linked to Zika viral load or Dengue fever
FINDINGS UCLA-led researchers have found that Zika viral load and the degree of Zika symptoms during pregnancy were not necessarily associated with problems during pregnancy or fetal abnormalities at birth. They also found that the presence of antibodies to previously acquired dengue fever was not necessarily connected to abnormalities during pregnancy or at birth.

A Seaweed Derivative Could Be Just What Lithium-Sulfur Batteries Need
A Seaweed Derivative Could Be Just What Lithium-Sulfur Batteries Need
Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists from the Department of Energyâ??s Lawrence Berkeley National Laboratory (Berkeley Lab) have made a surprising discovery that could fix this problem.

Silver atom nanoclusters could become efficient biosensors
Silver atom nanoclusters could become efficient biosensors
Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging. By combining chemistry and nanotechnology, the research community in recent years has developed a kind of extremely small nanoclusters consisting of only a few noble metal atoms bound to a DNA fragment.

Analysis of Complex Protein Interactions
The composition of specific functional protein complexes in their cellular environment can now be analysed with unprecedented resolution. The team led by junior group leader Dr Julien Béthune at Heidelberg University Biochemistry Center has developed a new technique which allows the scientists to overcome a long-standing hurdle in molecular cell biology.

Graphene encapsulation provides unprecedented view of the diffusion and rotation of fullerene molecules
Graphene encapsulation provides unprecedented view of the diffusion and rotation of fullerene molecules
Scientists at the University of Vienna have created a new hybrid structure, termed buckyball sandwich, by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine for the first time soccerball-like fullerenes, each consisting of sixty carbon atoms, and graphene, a one-atom thick layer of carbon.

Organic compound found in early stages of star formation
Organic compound found in early stages of star formation
Scientists seeking to understand the origins of life have found a new organic compound in the material from which a star like the Sun is forming. Researchers from Queen Mary University of London (QMUL) are part of a team that have for the first time detected methyl isocyanate (or CH3NCO) in a solar-type protostar, the kind from which our Sun and the Solar System formed.

Relation between comets and earthâ? s atmosphere uncovered
Relation between comets and earthâ? s atmosphere uncovered
Media releases, information for representatives of the media Media Relations (E) The difficult yet successful measurement of several isotopes of the noble gas xenon on comet 67P/Churyumov-Gerasimenko using the Bernese instrument ROSINA on the Rosetta probe shows that materials arrived on Earth due to comet impacts.

Imaging technique shows molecular machinery at work
The camera-based imaging platform Scott Blanchard and his team developed to track how individual proteins, called G protein-coupled receptors (GPCRs), respond to their environments. New imaging methods that allow researchers to track the individual protein molecules on the surface of cells have been developed by Weill Cornell Medicine investigators.

Scientists analysing Martian mudstones reveal chemistry of ancient lake in study
Scientists analysing Martian mudstones reveal chemistry of ancient lake in study
Imperial's Professor Sanjeev Gupta talks about the chemistry of rocks on Mars and what they reveal about a lake that has long since dried up. Professor Gupta, from Imperial College London's Department of Earth Science and Engineering , is part of NASA's Curiosity mission. Every day, analyses data on the geology of Mars that is beamed back from the Mars Science Laboratory mission's remote-controlled Curiosity rover.

Closing In On the Secret of Possible New Enzymes
Closing In On the Secret of Possible New Enzymes
Researchers at Heidelberg University have gained new knowledge on the possible biological function of patellamides. In laboratory experiments, they were able to demonstrate that this natural product displays important catalytic activity in combination with copper(II). The team of scientists headed by chemist Peter Comba developed a special method to determine whether this activity can also be observed in the patellamide-producing organisms.

Rover Findings Indicate Stratified Lake on Ancient Mars
Rover Findings Indicate Stratified Lake on Ancient Mars
NASA's Curiosity rover has discovered that an ancient lake on Mars had a chemical stratification similar to that of lakes on Earth'a potential prerequisite for the presence of life. Previous exploration by the rover revealed the presence of a lake more than 3 billion years ago in Mars's Gale Crater.

Nitrogen Oxides Emissions: Traffic Dramatically Underestimated as Major Polluter
Traffic contributes more to nitrogen oxide emissions in Europe than previously thought. This is the result of a current study carried out by scientists from the University of Innsbruck. The research team headed by Thomas Karl shows that even newer air quality models underestimate traffic related nitrogen oxide pollution by up to a factor of 4.
