Potential alternative to widely used contrast agent gadolinium. Some of the world’s greatest discoveries happened by accident. While the discovery of diamond dust’s potential as a future MRI contrast agent may never be considered a turning point in science history, its signal-enhancing properties are nevertheless an unexpected finding which may open-up new possibilities: Diamond dust glows brightly even after days of being injected. Does that mean it could perhaps one day become an alternative to the widely used contrast agent…
New study identifies NECTIN4 amplification as a promising biomarker – Under the leadership of PD Dr. Niklas Klümper, Assistant Physician at the Department of Urology at the University Hospital Bonn (UKB) and Clinician Scientist of the BMBF-funded ACCENT program and PD Dr. Markus Eckstein, senior physician at the Institute of Pathology at the Uniklinikum Erlangen of the Friedrich-Alexander-University Erlangen-Nürnberg (FAU), an interdisciplinary research team has published new findings that indicate which patients with advanced urothelial carcinoma could benefit in particular…
…to control valley polarization in bulk materials. An international team of researchers reports in Nature a new method that achieves valley polarization in centrosymmetric bulk materials in a non-material-specific way for the first time. This “universal technique” may have major applications linked to the control and analysis of different properties for 2D and 3D materials, which can in turn enable the advancement of cutting-edge fields such us information processing and quantum computing. The project was realised in collaboration between ICFO…
The magnetic sense of migratory birds is probably based on the protein cryptochrome 4, and a genetic study has now provided further support for this theory. A team of researchers from the University of Oldenburg and the Institute of Avian Research in Wilhelmshaven compared the genomes of several hundred bird species and found that the gene sequence for cryptochrome 4 has changed considerably during evolution. This suggests that cryptochrome 4 was selected to adapt to different environmental conditions. A possible…
Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is the considerable measuring time this technique usually requires, which often leads to lengthy acquisition times spanning minutes to hours. Researchers have developed a technique to speed up spectroscopic analysis. The results of the project led by Hanieh Fattahi, Research group leader at the Max-Planck-Institute of the Science of Light, in collaboration…
… with monolithically integrated terahertz detectors for industrial applications. The Ferdinand-Braun-Institut has developed a terahertz (THz) line scanner for plastic components, enabling cost-effective realization of larger scan line lengths in industrial environments. For the first time, the technology demonstrator is based entirely on monolithically integrated THz detectors. There is hardly anyone who hasn’t encountered it yet, as terahertz radiation (THz) is routinely used at airports for security checks. It penetrates clothing, organic tissue, and many other materials including plastics, polymers,…
Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes they utilize. Aqueous batteries use water as the solvent for electrolytes, significantly enhancing the safety of the batteries. However, due to the limited solubility of the electrolyte and low battery voltage, aqueous batteries typically have a lower energy density. This means that the amount of electricity stored per unit volume of aqueous battery is relatively low. In a new study…
…gives new hope to patient with terminal illness. Surgeons at NYU Langone Health performed the first-ever combined mechanical heart pump and gene-edited pig kidney transplant surgery in a 54-year-old woman with heart and kidney failure—a confluence of advances that showcase the possibility and hope of modern medicine. Doctors performed this feat in two stages: first surgically implanting the heart pump days before embarking on the landmark transplant, which included a gene-edited pig kidney and the pig’s thymus gland to aid…
LMU researchers have developed a method to determine how reliably target proteins can be labeled using super-resolution fluorescence microscopy. Modern microscopy techniques make it possible to examine the inner workings of cells in astonishing detail. “We can now observe the arrangement and interaction of individual proteins under the microscope,” says Professor Ralf Jungmann, Chair of Molecular Physics of Life at LMU and Max Planck Fellow at the MPI of Biochemistry. The biophysicist’s team recently developed the revolutionary RESI (Resolution Enhancement…
Scientists develop novel liquid metal alloy system to synthesize diamond under moderate conditions. Did you know that 99% of synthetic diamonds are currently produced using high-pressure and high-temperature (HPHT) methods?[2] A prevailing paradigm is that diamonds can only be grown using liquid metal catalysts in the gigapascal pressure range (typically 5-6 GPa, where 1 GPa is about 10,000 atm), and typically within the temperature range of 1300-1600 °C. However, the diamonds produced using HPHT are always limited to sizes of…
Thanks to ESA satellites, an international team including UNIGE researchers has detected a giant eruption coming from a magnetar, an extremely magnetic neutron star. While ESA’s satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays – high-energy photons – coming from the nearby galaxy M82. Only a few hours later, ESA’s XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team, including researchers from the University of Geneva (UNIGE), realised…
Weill Cornell Medicine investigators have uncovered a way to unleash in blood vessels the protective effects of a type of fat-related molecule known as a sphingolipid, suggesting a promising new strategy for the treatment of coronary artery disease. In the study, published March 8 in Circulation Research, the researchers showed that boosting levels of a sphingolipid called S1P in artery-lining endothelial cells slows the development and progression of coronary artery disease in an animal model. The lead author was Dr. Onorina Laura…
The 3.7 billion-year-old rocks may extend the magnetic field’s age by 200 million years. Geologists at MIT and Oxford University have uncovered ancient rocks in Greenland that bear the oldest remnants of Earth’s early magnetic field. The rocks appear to be exceptionally pristine, having preserved their properties for billions of years. The researchers determined that the rocks are about 3.7 billion years old and retain signatures of a magnetic field with a strength of at least 15 microtesla. The ancient…
As our battle against cancer rages on, the quest for more sophisticated and realistic models to study tumor development has never been more critical. Until now, research has relied on animal models and simplified cell culture methods, which are valuable but cannot fully capture the complex interplay of factors involved in tumor development. Even newer, more advanced models for studying cancer, such as organoids – tiny, lab-grown versions of organs – do not faithfully replicate the cell behaviors and tissue…
Storing and utilising energy with innovative sulphur-based cathodes. HU research team develops foundations for sustainable battery technology Electric vehicles and portable electronic devices such as laptops and mobile phones are unthinkable without lithium-ion batteries. The problem: highly toxic materials such as cobalt are often used for the cathodes of these batteries, which jeopardise the environment and the health of people in the countries where they are mined. In addition, the reserves of these metals are very limited. Sustainable and powerful…
… can monitor brain activity in real-time during brain surgery. The device represents a huge leap ahead to visualize brain activity to guide neurosurgeons. A thin film that combines an electrode grid and LEDs can both track and produce a visual representation of the brain’s activity in real-time during surgery–a huge improvement over the current state of the art. The device is designed to provide neurosurgeons visual information about a patient’s brain to monitor brain states during surgical interventions to…
