The research, which was conducted on mice, demonstrates how these tiny nanomachines are propelled by urea present in urine and precisely target the tumour, attacking it with a radioisotope carried on their surface. Bladder cancer has one of the highest incidence rates in the world and ranks as the fourth most common tumour in men. Despite its relatively low mortality rate, nearly half of bladder tumours resurface within 5 years, requiring ongoing patient monitoring. Frequent hospital visits and the need…
Solving major puzzle in Lunar Geology New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unravelling a mystery which has long eluded scientists. The study, published today in Nature Geoscience, reveals a key step in the genesis of these distinctive magmas. A combination of high temperature laboratory experiments using molten rocks, together with sophisticated isotopic analyses of lunar…
International research team measures isotopic composition of lunar rocks. An international team of geoscientists from the Universities of Münster and Bristol in England have explained why a large part of the moon is made up of unique rocks that do not occur on Earth. The results have now been published in the scientific journal “Nature Geoscience”. Their high Ti contents are ultimately believed to be derived from a distinct mineralogical layer formed as part of the unstable crystal pile that…
Geophysicists from Freie Universität Berlin among the researchers investigating human-induced earthquakes. It is common knowledge that humans have a big effect on the world and their natural environment. However, what may be less well-known is that humans can also induce earthquakes. Industrial activities such as geothermal energy production, fracking for oil and natural gas, and wastewater disposal can all lead to increased seismic activity that commonly takes the form of earthquakes. In extreme cases, these earthquakes can lead to casualties…
List group publishes their results with “Nature”. Aliphatic molecules are important for industry, but usually not very reactive. A new catalyst from Mülheim has changed that. The research group of Prof. Benjamin List has published their results with “Nature”. So-called aliphatic hydrocarbons play a major role in the chemical industry, but are not easy to handle from a scientific point of view. These special molecules form precursors of desired substances in many important reactions – for example in the production…
German Researcher at the Leibniz Institute DSMZ in Braunschweig develops new method for the derivatization of antibiotics. Professor Dr Yvonne Mast, Head of the Department of Bioresources for Bioeconomy and Health Research, and her working group at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures have developed a new method for the derivatization of antibiotics. Antibiotics are medicinally important compounds often produced by microorganisms. Such natural substances often have a chemically complex structure and hence can be difficult…
New discovery contradicts textbook models. Many important reactions related to climate and environmental processes take place where water molecules interface with air. For example, the evaporation of ocean water plays an important role in atmospheric chemistry and climate science. Understanding these reactions is crucial to efforts to mitigate the human effect on our planet. Textbook models will now need to be re-drawn after a team of researchers has found that water molecules at the surface of salt water are organized…
Tandem electrocatalytic-thermocatalytic conversion could help offset emissions of potent greenhouse gas by locking carbon away in a useful material. Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Columbia University have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure. As the…
The first 3D map of magnetic fields in our galaxy explains star-forming regions. A team of astronomers including those from the University of Tokyo created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from…
If we want to slow down global warming, we need to drastically reduce greenhouse gas emissions. Among other things, we need to do without fossil fuels and use more energy-efficient technologies. However, reducing emissions alone won’t do enough to meet the climate targets. We must also capture large quantities of the greenhouse gas CO2 from the atmosphere and either store it permanently underground or use it as a carbon-neutral feed material in industry. Unfortunately, the carbon capture technologies available today…
…enhances effectiveness of experimental cancer therapy. Did smokers do better than non-smokers in a clinical trial for an experimental cancer treatment? That was the intriguing question that led University of Iowa researchers and their colleagues to develop a drinkable, carbon monoxide-infused foam that boosted the effectiveness of the therapy, known as autophagy inhibition, in mice and human cells. The findings were recently published in the journal Advanced Science. Looking for ways to exploit biological differences between cancer cells and healthy…
… providing insights into evolution, biofuels, cellular aging. You may be familiar with yeast as the organism content to turn carbs into products like bread and beer when left to ferment in the dark. In these cases, exposure to light can hinder or even spoil the process. In a new study published in Current Biology, researchers in Georgia Tech’s School of Biological Sciences have engineered one of the world’s first strains of yeast that may be happier with the lights…
‘It’s a useful planet because it may be like an early Earth’ A team of astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It’s a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve. Young, hot, Earth-sized planet HD 63433d sits close to its star in the constellation Ursa Major, while two neighboring, mini-Neptune-sized planets…
Innovative, customized, and sustainable – these are the keywords for the numerous research projects of the Fraunhofer IPMS. At one of the leading conferences and trade fairs for photonics – SPIE Photonics West in San Francisco from January 27 to February 1, 2024 – the institute will present developments and advances in areas such as micro-optics, MEMS-based light modulators and biophotonics. The Fraunhofer Institute for Photonic Microsystems IPMS is one of the leading research institutes for the development and production…
Being able to observe micro-organisms and their cellular components is key to understanding fundamental processes that go on inside cells—and thus potentially developing new medical treatments. Microbiologists and biophysicists from the University of Bonn have now developed a method that makes the high-throughput process for observing molecules five times faster, enabling insights to be gained into hitherto unknown cellular functions. If our skin spends too long exposed to UV rays, e.g. from the sun, it can cause mutations in our…
The Leibniz Institute on Aging – Fritz-Lipmann Institute (FLI) developed an assessment system for fish health. Jena. The welfare of fish – that is what drives Dr. Beate Hoppe and her team every day. The animal keepers, scientists and veterinarians at the Leibniz Institute for Ageing Research (FLI) in Jena have spent six years meticulously collecting and evaluating data and have now published their findings in the Journal of the American Association for Laboratory Animal Science (JAALAS). What has long…
