The Baryon Antibaryon Symmetry Experiment (BASE) at CERN’s Antimatter Factory has set new limits on the mass of axion-like particles – hypothetical particles that are candidates for dark matter – and constrained how easily they can turn into photons, the particles of light. This is especially significant as BASE was not designed for such studies. The experiment’s new result, published by Physical Review Letters, describes this pioneering method and opens up new experimental possibilities in the search for cold dark…
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…
Discovering ‘axions’ could help answer one of the most puzzling questions in physics. One of the most high-profile mysteries in physics today is what scientists refer to as the “Strong CP Problem.” Stemming from the puzzling phenomenon that neutrons do not interact with electric fields despite being made up of quarks—smaller, fundamental particles that carry electric charges—the Strong CP Problem puts into question the Standard Model of physics, or the set of theories scientists have been using to explain the…
Astrophysicists scan the Galaxy for signs of life. Astrophysicists from Trinity College Dublin are scanning the Universe for “technosignatures” emanating from distant planets that would provide support for the existence of intelligent, alien life. Using the Irish LOFAR telescope and its counterpart in Onsala, Sweden, the team – led by Professor Evan Keane, Associate Professor of Radio Astronomy in Trinity’s School of Physics, and Head of the Irish LOFAR Telescope – plans to monitor millions of star systems. Scientists have been…
Clinical trial of people destined to develop early-onset Alzheimer’s disease shows eliminating amyloid from brain may prevent symptoms, supports need for confirmatory studies An experimental drug appears to reduce the risk of Alzheimer’s-related dementia in people destined to develop the disease in their 30s, 40s or 50s, according to the results of a study led by the Knight Family Dominantly Inherited Alzheimer Network-Trials Unit (DIAN-TU), which is based at Washington University School of Medicine in St. Louis. The findings suggest…
Fallow agricultural land and steppe-formation processes are evidently capable of having a much greater effect on global air quality than was previously assumed.
These microorganisms that oxidize methane anaerobically are an important component of the global carbon cycle and a major sink for methane on Earth.Methane – a…
Species distribution models are of only limited use in predicting the future distribution of mammals. This is the finding of a study of the climate niches of…

Optimized light paths, high-throughput laser scribing and the use of established coating processes paves the way to commercial viability – publication in nature energy. Researchers at the Karlsruhe Institute of Technology (KIT) have developed a prototype for fully scalable all-perovskite tandem solar modules. These modules have an efficiency of up to 19.1 percent with an aperture area of 12.25 square centimeters. This result, the first of its kind reported worldwide, was made possible by improving efficiency with optimized light paths,…
The climate-friendly NECOC process produces carbon out of the CO2 from ambient air. Germany is progressing on its way to climate neutrality – and has to close carbon cycles in its industries as soon as possible to get there. To reach the 1.5-degree target, the Intergovernmental Panel on Climate Change (IPCC) suggests to remove and permanently store already emitted CO2. “We have to find completely new technological solutions if we want to keep up industrial production,” says Dr. Benjamin Dietrich…
