Researchers create most complete model of complex protein machinery

Symbiotic algae living inside corals provide those animals with their vibrant color, as well as many of the nutrients they need to survive. That algae, and other microbes within the bodies of corals, have been extensively studied--yet until now, researchers have largely ignored the microbial communities just outside of the coral colonies.

Researchers of the University of Bonn identify extremely rare fusion of two white dwarfs

In addition to Ampere, Kelvin, Mol and Co., the kilogram also is now defined by a natural constant. In concrete terms, this means that the original kilogram, which has been the measure of all things for 130 years, has now served its purpose in Paris. This is made possible by the single crystals grown from the highly enriched isotopic silicon-28 at the Leibniz-Institut für Kristallzüchtung (IKZ).

Researchers at Tokyo Institute of Technology have found a simple, yet highly versatile, way to generate "chaotic signals" with various features. The technique consists of interconnecting three "ring oscillators," effectively making them compete against each other, while controlling their respective strengths and their linkages. The resulting device is rather small and efficient, thus suitable for emerging applications such as realizing wireless networks of sensors.

Ladder polymers -- molecules made of adjacent rings sharing two or more atoms -- are challenging to synthesize, because they require highly selective, quantitative reactions to avoid the formation of branching structures or of interruptions in the ring sequence in the polymer chain.

The anti tumor protein p53 can decide on the life or death of a cell: If it detects damage in the cell's genome, the protein pushes the cell to suicide. New research conducted at Technical University of Munich (TUM) shows that this inborn cancer prevention only works when special proteins, known as chaperones, allow it to take place.

The limestone skeleton of tropical corals already shows changes in chemical composition due to the increase in CO2 in the atmosphere. This is shown by the study of an international team recently published in Nature Communications.

• Immune cells prioritise the clearance of dead cells overriding their normal migration to sites of injury
• University of Sheffield research paves the way for new therapies to manipulate how white blood cells get to and are kept at sites of injuries during healing

Researchers from Washington State University and Ohio State University have developed a low-cost, easy way to make custom lenses that could help manufacturers avoid the expensive molds required for optical manufacturing.

As the only terrestrial planet, the Earth has a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Both are essential for life to develop on Earth. Planetologists from the University of Münster have now been able to show for the first time that water came to Earth with the formation of the Moon some 4.4 billion years ago. The results are published in the current issue of the journal "Nature Astronomy".

Researchers quantify rare CO2 variants using laser spectroscopy

Dr. Jan P. Meier-Kolthoff and Associate Professor Dr. Markus Göker develop Type Strain Genome Server (TYGS)

Swiss and Tübingen palaeontologists identify four million-year old species by their teeth - providing a model for evolutionary diversity among freshwater fish

Producing cement takes a big toll on our climate: Around eight per cent of annual global carbon dioxide emissions can be attributed to this process. However, the demand for cement continues to rise. A team of geoscientists from Martin Luther University Halle-Wittenberg (MLU) has found a way to produce more environmentally friendly and sustainable alternatives. In the journal "Construction and Building Materials" they describe how industrial residues can be used to produce high-quality, climate-friendly materials.

When it gets cold outside in winter, people like to cuddle up together. This mechanism is vital for the survival of bees: they are located in the centre of the hive. A functioning temperature regulation within the hive is also crucial throughout the year, both for the brood and for combating the so-called varroa mite. Scientists at the Max Planck Institute for Polymer Research (MPI-P) led by Prof. Katharina Landfester and Dr. Stanislav Balouchev are working on a project funded by the Volkswagen Foundation to measure and ultimately actively influence the temperature distribution in a hive.

Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma -- the state of matter composed of free electrons and atomic nuclei, or ions -- that fuels fusion reactions.

A detailed new model of a bacterial secretion system provides directions for developing precisely targeted antibiotics

UC Riverside researchers develop new drugs that target therapeutically relevant protein surfaces

The new 5G radio standard is intended to make our communication and data transmission considerably faster and more efficient. For this to be possible, a sufficient number of transmission masts are needed. In a seminar held in the Department of Architecture at Technische Universität Kaiserslautern, participants discussed the possible design of these masts. For their models, the students have opted for the environmentally friendly material wood. The best designs are currently being constructed. Over the next few weeks, it is planned to install them as part of a pilot project in Kaiserslautern.
