A global library – full of hailstones instead of books – is helping researchers to better understand and predict damaging storms. A University of Queensland library – full of hailstones instead of books – is helping researchers to better understand and predict damaging storms. Dr Joshua Soderholm, an Honorary Senior Research Fellow from UQ’s School of the Environment, and lead researcher PhD candidate Yuzhu Lin from Penn State in the US, have found storm modelling outcomes change significantly when using…
These zinc-air batteries, smaller than a grain of sand, could help miniscule robots sense and respond to their environment. A tiny battery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines. The new battery, which is 0.1 millimeters long and 0.002 millimeters thick — roughly the thickness of a human hair — can capture oxygen from air and…
Utah geophysicists find link between seismic waves called PKP precursors and anomalies in Earth’s mantle. For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds. The origin the precursor signals, which arrive ahead of the main seismic waves that travel through Earth’s core, has remained unclear, but research led by University of Utah geophysicists sheds…
Scientists highlight diversity and editability in photosensitive molecules. Scientists from Tokyo Metropolitan University have identified a new photoreceptor in cyanobacteria with a modification in part of its structure which makes it sensitive to green/teal light. The photoreceptor belongs in a family usually sensitive to red/green light in the environment. They identified the parts of its amino acid structure responsible for this behavior; editing them helped restore sensitivity to red and green light, a remarkable example of molecular “plasticity” in action….
In an analysis of smartphones of ten manufacturers, researchers at TU Graz have found that the Android kernels used are vulnerable to known attacks – so-called one-day exploits – despite existing protection mechanisms. Smartphones are a constant companion and important work tool for many people. In addition to contacts, appointments and emails, the devices are increasingly being used for sensitive tasks such as online banking or official matters. This increases the safety requirements. As Lukas Maar, Florian Draschbacher, Lukas Lamster…
Researchers at the Paul Scherrer Institute PSI have analysed which regions of the world could produce hydrogen most cost-effectively in order to build an economy based on this alternative energy carrier rather than fossil-fuel based alternatives. One of their findings is that simply replacing fossil fuels by electricity and hydrogen will not put an end to greenhouse gas emissions. The study is being published today in the journal Nature Communications. Switzerland aims to become climate-neutral by 2050. This means that…
– at ISAT of Coburg University of Applied Sciences. Shadow mask lithography can be used to create tiny patterns on surfaces. The Institute of Sensor and Actuator Technology (ISAT) at Coburg University of Applied Sciences announces the first successful fabrication of plasmonic nanostructure by shadow mask lithography – and this has big potential for the development of highly sensitive sensors. Nano comes from the Greek, meaning dwarf, and nanotechnology is the science and technology of tiny nanoparticles. There are so-called…
– a European monitoring project at ZMT. Biodiversity is difficult to observe and assess in the open ocean, which is vast and difficult to access. The European research project “Monitoring the Open-Ocean Biodiversity with Fishers” (MOOBYF) is now pursuing a new strategy for which it draws on ZMT’s deep-rooted collaboration with the local population that lives from fishing in the Indian Ocean. “Fish Aggregating Device” (FAD) made of bamboo off Gondol on the north coast of Bali. © MOOBYF The…
The electron shell of atoms acts as an “electromagnetic shield”, preventing direct access to the nucleus and its properties. A team in the group of Klaus Blaum, director at the Max Planck Institute for Nuclear Physics in Heidelberg, has now succeeded in precisely measuring the effect of this shielding in beryllium atoms. The magnetic moment of beryllium-9 could was also determined with 40 times better precision than before. Such precision measurements are not only relevant to fundamental physics. They also…
Nanoscale optoelectronics is a rapidly advancing field focused on developing electronic and photonic devices at the nanometer scale. These tiny devices have the potential to revolutionize technology, making components faster, smaller, and more energy-efficient. Achieving precise control over photoreactions at the atomic level is crucial for miniaturizing and optimizing these devices. Localized surface plasmons (LSPs), which are light waves generated on nanoscale material surfaces, have emerged as powerful tools in this domain, capable of confining and enhancing electromagnetic fields. Until…
Revolutionary Discovery at the University of Bremen. Scientists at the University of Bremen have successfully isolated a nitrene for the first time, which was previously considered impossible to isolate. The discovery was published in the renowned “Science” journal. “Our finding is a great success for foundation research. Chemistry textbooks will have to be rewritten,” states Professor Jens Beckmann, head of the research team. “We have shown that it is possible to control these highly reactive compounds in the laboratory. This…
The research was carried out in Dr. Johannes Karges’ Medicinal Inorganic Chemistry group in collaboration with doctoral student Nicolás Montesdeoca and two Bachelor students, Lukas Johannknecht and Elizaveta Efanova, and with the support of Dr. Jaqueline Heinen-Weiler from the Medical Imaging Center at Ruhr University Bochum. Two types of programmed cell death In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to…
Researchers have demonstrated a technique for printing thin metal oxide films at room temperature, and have used the technique to create transparent, flexible circuits that are both robust and able to function at high temperatures. “Creating metal oxides that are useful for electronics has traditionally required making use of specialized equipment that is slow, expensive, and operates at high temperatures,” says Michael Dickey, co-corresponding author of a paper on the work and the Camille and Henry Dreyfus Professor of Chemical…
IOW researchers investigate causes and effects. Marine heatwaves – periods in which the upper water layers in the sea temporarily become exceptionally warm – are occurring with increasing frequency worldwide. Recent studies by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) have now confirmed this trend also for the Baltic Sea. IOW researchers analysed very large meteorological and hydrographic data sets and identified the specific wind and weather conditions that cause Baltic Sea heatwaves. They also analysed for the…
Researchers at the Paul Scherrer Institute PSI have been improving the resolution of a process known as photolithography. They hope to use their technique to help advance the miniaturisation of computer chips. Miniaturising computer chips is one of the keys to the digital revolution. It allows computers to become ever smaller and, at the same time, more powerful. This in turn is a prerequisite for developments such as autonomous driving, artificial intelligence and the 5G standard for mobile communications. Now…
An innovative combination of tissue simulation, an authoring tool for creating custom learning content, and special haptic arms will make this possible. The long and complex training of surgeons is intended to prepare them as best as possible for the successful performance of complex procedures such as bone operations. With the help of virtual reality (VR), it is possible to realistically depict surgical situations and test training with virtual patients free of risk. However, current methods still have their limits…
