The ecological impact of herbivore dung on plant communities
Xingzhao Sun of the research group Wildness, biodiversity and ecosystems under change of the Vrije Universiteit Brussel (VUB) explored the complex ecological interactions between herbivore dung and plant communities, providing new insights into the r.....»»
Study of cloud movement in the Arctic could provide better understanding of climate change in the region
Special features of the Arctic climate, such as the strong reflection of the sun's rays off the light snow or the low position of the sun, amplify global warming in the Arctic. However, researchers are often faced with the challenge of modeling the u.....»»
James Webb spots another pair of galaxies forming a question mark
Webb has stumbled across a question mark-shaped galaxy, and the reasons for its uniqueness reveal how the telescope looks at some of the most distant galaxies......»»
New Horizons spacecraft measurements shed light on the darkness of the universe
Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA's New Horizons spacecraft, by making the most precise, direct measurements ever of the total.....»»
Study identifies keys to success of evidence-based decision making
Evidence-based decision making (EBDM)—using the best available evidence from multiple sources to make informed decisions—is critical to the success of any organization. In a new study, researchers have explored what makes EBDM work. They found th.....»»
Researchers start first low frequency search for alien technology in distant galaxies
The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a study using the Murchison Widefield Array (MWA) in Western Australia. Led by Dr. Chenoa Tremblay of the SETI Institute and Pro.....»»
Novel carbon nanohorn-based treatment enables efficient delivery of drugs in cancer therapy
Cancer remains one of the most challenging diseases to treat due to its complexity and tendency to metastasize (spread into, or invade, nearby tissues or distant places in the body to form new tumors). Traditional therapies, such as chemotherapy and.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes
An international team of scientists is the first to report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays......»»
From plows to pixels: Comprehensive rice mapping with satellite technology
While satellite technology might seem distant and space-bound, its benefits can be seen everywhere......»»
Chalk-based coating creates a cooling fabric
In the scorching heat of summer, anyone who spends time outside—athletes, landscapers, kids at the park or beachgoers—could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or transfer heat away from the bo.....»»
Astronomers explore the properties of quasar 1604+159
Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, in.....»»
Study explores the transformation of educational system with the advent of AI
The advent of artificial intelligence (AI) presents several new and exciting opportunities for improving the quality of education. While several ways of integrating AI into schooling have been explored, only a few of them consider changing the tradit.....»»
Cosmic count exceeds expectation: Alpha Magnetic Spectrometer on ISS reveals surplus of cosmic rays
Cosmic rays confound scientists once again. The latest analysis of data collected by the Alpha Magnetic Spectrometer (AMS) on board the International Space Station has revealed a surprising surplus of cosmic rays made of deuterons—atomic nuclei mad.....»»
A galactic "comet" called Terzan 5 illuminates a 100-year-old puzzle about cosmic rays
When my colleagues and I set to work on a century-old cosmic mystery, we found an unexpected celestial laboratory in Terzan 5, a dense star cluster currently plunging through our galaxy at breakneck speed......»»
PhAI—an AI system that figures out the phase of x-rays that crystals have diffracted
A trio of chemists at the University of Copenhagen has developed an AI application that can be used to figure out the phase of x-rays that crystals have diffracted as part of efforts to predict the structure of small molecules......»»
Increasing solid-state electrolyte conductivity and stability using helical structure
Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte—a solution that allows ions to move.....»»
Fewer car journeys and more flights: How COVID-19 has changed the way we travel
Four years after the outbreak of COVID-19, the pandemic seems like a distant memory for many. Yet its impacts on our lifestyle today are often profound and long-lasting, with many researchers on a mission to quantify it across sectors......»»
New X-ray world record: Looking inside a microchip with 4 nanometer precision
In a collaboration with EPFL Lausanne, ETH Zurich and the University of Southern California researchers at the Paul Scherrer Institute PSI have used X-rays to look inside a microchip with higher precision than ever before. The image resolution of 4 n.....»»
Scientists find a human "fingerprint" in the upper troposphere"s increasing ozone
Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant.....»»
