A step towards cheap aluminium batteries
A step towards cheap aluminium batteries
The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A promising new candidate is aluminium batteries, which are made from cheap and abundant raw materials. Scientists from Maksym Kovalenko's research group, which is based at both ETH Zurich and in Empa's Laboratory for Thin Films and Photovoltaics , are researching and developing batteries made from abundant raw materials.

"Failure is not an option": A lab visit to Prof. Friedemann Kiefer
Prof. Kiefer, what scientific topic are you working on right now? My group is investigating how lymphatic vessels form and how they are preserved in a functional state. During development, the lymphatic vessel system adopts a characteristic structure and we would like to understand, which molecular mechanisms are responsible for the formation of the prototypic shape of this vessel tree.

Traces in scrap
Traces in scrap
Last year Empa's inorganic analytics lab was granted the status of "Reference Laboratory" within the scope of the ProSUM project, funded by the EU. Fine-grained samples of shredder waste from scrapped cars, e-waste or mine dumps from all over Europe end up here. Empa chemists find out what is in them, what is worth extracting and what could be dangerous for staff at recycling plants.

Search engine for «smart wood»
Search engine for «smart wood»
Mark Schubert modifies wood properties with the aid of the enzyme laccase. However, the search for suitable ingredients is complex - a bit like trying to find the key to an unknown lock. Instead of long, expensive series of experiments, Schubert uses artificial intelligence as it gets him to the goal more quickly.

Researchers chart the 'secret' movement of quantum particles
Researchers chart the ’secret’ movement of quantum particles
Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. In a theoretical paper published in the journal Physical Review A , they have shown that the way that particles interact with their environment can be used to track quantum particles when they're not being observed, which had been thought to be impossible.  We can verify old predictions of quantum mechanics, for example that particles can exist in different locations at the same time.

Graphene well-suited for rapid internet
Introduction: Ben Van Duppen (University of Antwerp) and his international colleagues are paving the way for a successful internet of things. The ultra-thin material graphene can make the internet several thousand times faster. By cutting the material into very small strips, the researchers from several institutions, including the University of Antwerp, discovered a new effect that could give a strong boost to fibre internet.

Exploring the phenomenon of superconductivity
Exploring the phenomenon of superconductivity
Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter where the constituent particles pair up when limited to two dimensions. The findings from the field of quantum physics may hold important clues to intriguing phenomena of superconductivity. Superconductors are materials through which electricity can flow without any resistance once they are cooled below a certain critical temperature.

A century of galaxy discrimination revealed by giant European astronomy survey
A huge European astronomy survey, whose results are released today (21 December 2017), has revealed that the view of the Universe provided by traditional optical telescopes is seriously biased. The Herschel ATLAS (H-ATLAS) was a survey carried out by an international team led by researchers at Cardiff University with European Herschel Space Observatory in the far-infrared waveband, which consists of electromagnetic waves with wavelengths 200 times greater than optical light.

Sunlight holds the key to planet’s shine
Scientists have discovered how the sun's influence on the remote planet Uranus changes its brightness in the sky. Changes in solar activity influence the colour and formation of clouds around the planet, researchers at Oxford and Reading universities found. The icy planet is second furthest from the sun in the solar system and takes 84 Earth years to complete a full orbit - one Uranian year.

Increased physical fitness may offset cognitive deterioration in dementia
Increased physical fitness may offset cognitive deterioration in dementia
Physical fitness is associated with better cognitive performance in older adults with dementia, according to a new study from UCL. The positive effects were found to be independent of past levels of exercise and illness duration, suggesting it's never too late to benefit from good levels of physical fitness, even after the onset of dementia.

Neutron-star merger creates new cosmic mysteries
An international team including Associate Professor Tara Murphy has been studying a neutron star collision and found an unusual cocoon of debris, raising doubts about the source of short gamma ray bursts. The neutron-star merger announced in October has solved one mystery - where gold comes from - but has also raised other questions, an international team reports in the journal Nature .

New depth sensors could be sensitive enough for self-driving cars
For the past 10 years, the Camera Culture group at MIT's Media Lab has been developing innovative imaging systems - from a camera that can see around corners to one that can read text in closed books - by using "time of flight," an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor.

Cosmic Filament Probes Our Galaxy's Giant Black Hole
Cosmic Filament Probes Our Galaxy’s Giant Black Hole
The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy's supermassive black hole is the latest discovery to tantalize astronomers. In 2016, Farhad Yusef-Zadeh of Northwestern University reported the discovery of an unusual filament near the center of the Milky Way Galaxy using the NSF's Karl G. Jansky Very Large Array (VLA).

New technique allows rapid screening for new types of solar cells
New technique allows rapid screening for new types of solar cells
The worldwide quest by researchers to find better, more efficient materials for tomorrow's solar panels is usually slow and painstaking. Researchers typically must produce lab samples - which are often composed of multiple layers of different materials bonded together - for extensive testing. Now, a team at MIT and other institutions has come up with a way to bypass such expensive and time-consuming fabrication and testing, allowing for a rapid screening of far more variations than would be practical through the traditional approach.

Early disease diagnosis could be dramatically improved with new detection system
Early disease diagnosis could be dramatically improved with new detection system
By attaching specialised molecules to the backbone of DNA, researchers have made it easier to detect rare molecules associated with early disease. The presence of, or changes in the concentration of, certain proteins in biological fluids can be indicators of disease. However, in the early stages of disease these ‘biomarkers' can be difficult to detect, as they are relatively rare.

The fate of primordial germ cells: CiM researchers show how primordial germ cells follow their destiny and give rise to sperm and egg cells
The fate of primordial germ cells: CiM researchers show how primordial germ cells follow their destiny and give rise to sperm and egg cells
When an embryo develops, single cells acquire specific fates that allow them to perform specific tasks in the adult organism. The primordial germ cells are formed very early in embryonic development and migrate within the embryo to the developing testis or the ovary, where they give rise to sperm and egg cells.

Hidden bridge between quantum experiments and graph theory uncovered using Melvin
An answer to a quantum-physical question provided by the algorithm Melvin has uncovered a hidden link between quantum experiments and the mathematical field of Graph Theory. Researchers from the Austrian Academy of Sciences and the University of Vienna found the deep connection between experimental quantum physics and this mathematical theory in the study of Melvin's unusual solutions, which lies beyond human intuition.
