A team including researchers from the Helmholtz-Zentrum Hereon has developed new methods for repairing the latest generation of aircraft engine blades as part of the “Novel Engine Repair Methods” project funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK). The Hereon researchers together with Lufthansa Technik AG were able to develop two patentable repair processes. Minimizing resource usage is a major goal of modern industry, with a longer service life being the best way to achieve…
Joint study by MHH and HZI: vaccine proves safe and effective against liver fibrosis and liver cancer. Liver cancer is the third most common cause of cancer-related deaths worldwide. So far, the treatment options for two types of liver cancer, hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), have been inadequate, while the number of new cases has been rising. A study by researchers at the Hannover Medical School (MHH) and the Helmholtz Centre for Infection Research (HZI) now offers hope. A…
In a first for imaging, new microscope captures details, 3D motion of molecules in liquid. Understanding the nitty gritty of how molecules interact with each other in the real, messy, dynamic environment of a living body is a challenge that must be overcome in order to understand a host of diseases, such as Alzheimer’s. Until now, researchers could capture the motion of a single molecule, and they could capture its rotation — how it tumbles as it bumps into surrounding…
Eddies in an exotic liquid known as a superfluid merge to form large vortices, analogous to how cyclones form in the turbulent atmosphere. The new research, by a team from The University of Queensland, the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) and the ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) will be important for emerging technological applications of superfluidity, such as precision sensing. Lead author and theorist Dr Matt Reeves said the team’s results…
Green hydrogen is an important component in a climate-neutral energy system. It is produced by electrolytically splitting water with wind or solar power and stores this energy in chemical form. But currently, the production of green hydrogen is not yet economical or efficient enough. The key to solving this problem is through the development of innovative electrocatalysts, which should not only work with high efficiencies but should also be available and inexpensive. In addition to transition metals, which are already…
A pH-sensitive drug delivery system in T cells using C-terminal dendrimers with Phenylalanine. T cells, also known as lymphocytes, have important roles in various immune reactions. However, there are only a few reports on delivery systems into T cells. Realizing this, it is essential to work and actively contribute in controlling immune systems. Associate Professor Chie Kojima and her co-workers from Department of Applied Chemistry, Graduate School of Engineering, Osaka Prefecture University (OPU), collaborating with Professor Ikuo Fujii and Ikuhiko…
Optimized approach simplifies underwater optical data links; could enable devices that transmit data and produce power. Although solar cells are typically designed to turn light into power, researchers have shown that they can also be used to achieve underwater wireless optical communication with high data rates. The new approach—which used an array of series-connected solar cells as detectors—could offer a cost-effective, low-energy way to transmit data underwater. “There is a critical need for efficient underwater communication to meet the increasing…
… compatible with patient biopsies to fight metastasis. METPlatform allows researchers to investigate patients’ own tumour tissue. It is simple, fast, cheap, and “infinitely superior to other screening methods”. They have discovered that HSP90 inhibitors may be useful in treating brain metastases. It is estimated that about a quarter of cancer patients are at risk of brain metastases, a rate that is increasing especially among those who suffer relapses after having undergone different cancer treatments. This, in addition to the…
Official kick-off meeting will take place on February 17th and 18th: The second research mission of the German Marine Research Alliance (DAM), “sustainMare” (“Protection and Sustainable Utilization of Marine Environments”) analyzes our utilization of seas and coasts. Rising sea levels, ocean warming and acidification, together with pollution and over-utilization of ecosystems are causing profound problems. Two pilot projects and five collaborative projects investigate the ecological, economic and social impacts of utilization and stressors on the North and Baltic Seas. The…
The MATISSE instrument at the European Southern Observatory’s Very Large Telescope Interferometer has observed a cloud of cosmic dust at the centre of the galaxy NGC 1068 (also known as Messier 77 or M77) hiding a supermassive black hole. The findings of an international team of astronomers including scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, have confirmed predictions made around 30 years ago and are giving astronomers new insight into the mechanisms of “active galactic…
Researchers of the Max-Planck-Institut für Eisenforschung publish their latest findings in the journal Nature. Due to its low density, high strength, and abundance, aluminium and its alloys are widely used for example in constructions, consumer electronics and for vehicles including cars, ships, trains and planes. However, aluminium alloys are prone to hydrogen embrittlement causing catastrophic failure during service if not noticed early enough. Compared to steel, the effects of hydrogen in aluminium are not well understood. Dr. Huan Zhao, postdoctoral…
Scientists at the Berlin Institute of Health at Charité (BIH) have teamed up with a company called Cellbricks to develop a 3D printer that can produce a biological wound closure: Using a mix of gelatin and skin cells, the device prints a perfectly fitting bandage that can be used to close large wounds. This could be a good alternative to autologous skin grafting, and not just for burn victims on Earth: Astronauts could also be treated individually far away from…
University of Wisconsin–Madison physicists have made one of the highest performance atomic clocks ever, they announced Feb. 16 in the journal Nature. Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to losing just one second every 300 billion years and is the first example of a “multiplexed” optical clock, where six separate clocks can exist in the same environment. Its design allows the team to test ways to search for…
Researchers at the University of Nottingham have devised a revolutionary new technique for measuring the microscopic elasticity of materials for the first time. Known as SRAS, the technology works by measuring the speed of sound across the material’s surface. The Engineering and Physical Sciences Research Council (EPSRC)-funded innovation uses high-frequency ultrasound to produce microscopic resolution images of the microstructure and maps the relationship between stresses and strains in the material (the elasticity matrix). These crystals are normally invisible to the…
In northern Spain, wild honeybees use hollow electricity poles as nesting cavities. Natural areas in the surroundings promote the colonies’ chances to survive the winter. Until recently, experts considered it unlikely that the honeybee had survived as a wild animal in Europe. In a current study, biologists Benjamin Rutschmann and Patrick Kohl from Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, show that wild honeybees still exist in the region of Galicia in the northwest of Spain. The researchers describe where to…
Researchers at ETH Zurich have developed a new algorithm that allows them to model the dynamics of physical systems from observations. In the future it could be applied to the onset of turbulence and tipping points in climate. Modelling dynamically evolving physical systems is at the core of science and technology. Engineers need to know how the wings of a new airplane model will vibrate under particular flight conditions, and climate scientists are trying to predict how global temperatures and…
