The chemical composition of a material alone sometimes reveals little about its properties. The decisive factor is often the arrangement of the molecules in the atomic lattice structure or on the surface of the material. Materials science utilizes this factor to create certain properties by applying individual atoms and molecules to surfaces with the aid of high-performance microscopes. Using artificial intelligence, a new research group now wants to take the... Read more ›

The synchronization of data from two natural climate archives -- a speleothem from the Herbstlabyrinth Cave in Hesse (Germany) and ice cores from Greenland -- offers new insights into the chronology of abrupt climate changes in Central Europe. According to the analysis, the devastating eruption of the Laacher See volcano in what is now Rhineland-Palatinate occurred earlier than previously assumed and hence could not have triggered the sudden-onset cold period...

In an interdisciplinary and transdisciplinary study, an international team examined the social risks for Arctic regions associated with thawing permafrost. They identified five key risks related to infrastructure, transport and supply, water quality, food security and health. The scientists found that the thawing permafrost posed an increased risk of exposure to infectious diseases and release of contaminants, and interruptions of supply routes. Read more ›

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact crater 66 million years ago. A new study questions this scenario. Using groundbreaking empirical measurements of sulfur within the related Cretaceous-Paleogene (K-Pg) boundary layer, the international team has demonstrated that the role of sulfur during the...

Researchers carried out an archeogenetic study of human remains from more than 700 individuals from the Early Middle Ages. Two large burial sites, Modling and Leobersdorf, have been genetically analyzed in their entirety. The surprising result was that the individuals from Leobersdorf were mostly of East Asian origin, while those buried in Modling mostly had European ancestry. Both communities lived next to each other for at least six generations. Read more ›

In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At that time, it began emitting radio waves at 60 times the previous intensity over just a few months, behavior which has never been monitored in real time for a supermassive black hole. Imaging also clearly shows... Read more ›

A new report shows the benefit of wearing contact lenses for slowing myopia has a lasting effect -- good news since 50% of the world (5 billion people) will likely be nearsighted by 2050. Read more ›

A research team has discovered another piece in the puzzle of the formation of the Moon and water on Earth. The prevailing theory was that the Moon was the result of a collision between the early Earth and the protoplanet Theia. New measurements indicate that the Moon formed from material ejected from the Earth's mantle with little contribution from Theia. In addition, the findings support the idea that water could...

Amid a global surge in measles cases, new research suggests that undernutrition may be exacerbating outbreaks in areas suffering from food insecurity. A study involving over 600 fully vaccinated children in South Africa found those who were undernourished had substantially lower levels of antibodies against measles. Read more ›

For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 million light-years away, and is 1/100,000th the brightness of the faintest star visible to the human eye. Yet, a century ago, its discovery by Edwin Hubble opened humanity's eyes as to how large the universe really is,... Read more ›

Researchers have described the neurodegeneration that occurs in the nervous system of the bowel in Batten disease, a rare and fatal genetic condition. In their latest study, a team showed that gene therapy to the bowel in mice modeling Batten disease reduced symptoms and extended lifespan. Read more ›

Researchers have demonstrated new wearable technologies that both generate electricity from human movement and improve the comfort of the technology for the people wearing them. The work stems from an advanced understanding of materials that increase comfort in textiles and produce electricity when they rub against another surface. Read more ›

A new twist on a decades-old anticancer strategy has shown powerful effects against multiple cancer types in a preclinical study. The experimental approach, which uses tiny capsules called small extracellular vesicles (sEVs), could offer an innovative new type of immunotherapy treatment and is poised to move toward more advanced development and testing.
