The Last Mysteries of Mica
The Last Mysteries of Mica
A well-known mineral is once again the center of attention thanks to applications in electronics: the Vienna University of Technology shows that mica still has surprises in store. At first glance, mica is something quite ordinary: it is a common mineral, found in granite for example, and has been extensively studied from geological, chemical and technical perspectives.

Space collaboration including Sussex scientist makes icy discovery which sheds light on the building blocks of life
In a development believed to shed light on the building blocks of life, an international team of scientists, including Prof Wendy Brown from the University of Sussex, has discovered diverse ices in the darkest, coldest regions of space so-far measured, which are around 500 light years from Earth. The discovery within a molecular cloud was made by scientists from the IceAge project, an international consortium of academics using the James Webb Space Telescope (JWST), to observe the building blocks of life.

Scientists open new window on the physics of glass formation
Research from an international team of scientists has cast new light on the physics of vitrification - the process by which glass forms. Their findings, which centre on analysis of a common feature of glasses called the boson peak, could help pave the way for new developments in materials science. The peak can be observed in glass when special equipment is used to study the vibrations of its constituent atoms, where it spikes in the terahertz range.

Actin affects the spread of cancer in several ways
The transport of molecules along the cell's skeleton plays a role in cancer metastasis, Freiburg researchers show Metastases occur when cancer cells leave a primary tumor and spread throughout the body. For this, they have to break connections with neighboring cells and migrate to other tissues. Both processes are promoted by signalling molecules released by the cancer cells, which thereby increase the malignancy of tumors.

Colour images from the shadow of a sample
Colour images from the shadow of a sample
Researchers at Göttingen University develop new method for X-ray colour imaging A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole sample.

New catalyst design could make better use of captured carbon, researchers say
A new catalyst design created by researchers at the University of Toronto's Faculty of Applied Science & Engineering could significantly improve the practicality of an electrochemical process that converts captured carbon dioxide into multi-carbon molecules - some of the key building blocks of the chemical industry.

James Webb Space Telescope identifies origins of icy building blocks of life
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discovered the deepest and coldest ice ever detected in such a molecular cloud.

Researchers unravel the complex reaction pathways in zero carbon fuel synthesis
Researchers have used isotopes of carbon to trace how carbon dioxide emissions could be converted into low-carbon fuels and chemicals. The result could help the chemical industry, which is the third largest subsector in terms of direct CO2 emissions, recycle its own waste using current manufacturing processes.

Physical effect also valid in the quantum world
Physical effect also valid in the quantum world
Researchers at the University of Bonn confirm validity of a central theorem of physics for Bose-Einstein condensates Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties of the quantum "superparticles" and deduce system characteristics that would otherwise be difficult to observe.

Stefan Rüdiger appointed as Professor of Protein Chemistry of Disease
Utrecht University has appointed Stefan Rüdiger as Professor of Protein Chemistry of Disease. Chemist Rüdiger and his group aim to tackle diseases that are caused by protein misfolding, such as Alzheimer's disease and Huntington's disease. They focus on how chaperones, proteins that aid other proteins to fold into their proper shape, control protein quality.

A new, better technology for X-ray laser pulses
A new, better technology for X-ray laser pulses
Simpler and much more efficient than ever before: A new technology for producing X-ray laser pulses has been developed at TU Wien. The X-rays used to examine a broken leg in hospital are easy to produce. In industry, however, X-ray radiation of a completely different kind is needed - namely, X-ray laser pulses that are as short and high-energy as possible.

Underlying assumptions of air quality need to be redefined
Underlying assumptions of air quality need to be redefined
Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental assumption for air quality forecasting has to be reinterpreted for urban areas. Measurements by an international team led by atmospheric scientist Thomas Karl of the University of Innsbruck also show that direct nitrogen dioxide emissions are overestimated.

From molecules to organisms
From molecules to organisms
How did life on Earth first emerge? And how was it able to prosper and evolve? researchers are involved in the quest to find answers to these fundamental questions. Since time immemorial, humanity has pondered the question of how life on Earth first began. Ancient cultures declared the creation of the world and the origin of life to be the work of gods and other divine beings.

New ’chain mail’ material is tough and flexible
The individual building blocks of a catenane are polyhedral molecules - a type of adamantane - that link arms to form a 2D mesh or 3D network that is sturdy but flexible. University of California, Berkeley, chemists have created a new type of material from millions of identical, interlocking molecules that for the first time allows the synthesis of extensive 2D or 3D structures that are flexible, strong and resilient, like the chain mail that protected medieval knights.

Improving perovskite solar cell resistance to degradation
Improving perovskite solar cell resistance to degradation
Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.

Do Electrons Spin?
Deep inside all matter in the universe, electrons are buzzing around and behaving as if they are twirling around on their axes like spinning tops. These "spinning" electrons are fundamental to quantum physics and play a central role in our understanding of atoms and molecules. Other subatomic particles spin, too, and the study of spin has technical applications in the fields of chemistry, physics, medicine, and computer electronics.

Experimental physicists take step toward understanding natural quantum systems
Experimental physicists take step toward understanding natural quantum systems
"Suppose you knew everything there was to know about a water molecule - the chemical formula, the bond angle, etc.," says experimental physicist  Joseph Thywissen . "You might know everything about the molecule, but still not know there are waves on the ocean - much less how to surf them," he says.
