Autumn walks in Britain are glorious, as the foliage changes color and cool, crisp air begins to bite. However, some of these European trees hide a much darker secret. For example, the yew tree's lovely red arils—the cup-shaped coverings around the seeds—carry toxins that may have been used to poison arrow tips in the past.
Two recent review articles in the journals Trends in Ecology & Evolution and Fish and Fisheries, to which researchers from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) contributed, focus on the influence of humans on the diversity of fish behavior and on how management can help preserve this diversity.
Researchers from the Faculty of Physics at the University of Warsaw, the Military University of Technology (Poland), IBM Research Zurich and the French National Centre for Scientific Research (CNRS) have observed a new quantum state of matter known as a supersolid in an exciton-polariton Bose-Einstein condensate. Remarkably, the phenomenon occurs not at temperatures close to absolute zero, but at room temperature. The results have been published in Science Advances.
The more than 100 bacterial species of the genus Vibrio are important in marine ecosystems because they contribute to the carbon cycle and other ecological processes, but they can also be significant pathogens for both humans (they can cause cholera) and animals (they can drastically reduce productivity in fish and crustacean farms [e.g., prawns] or cause coral bleaching). Identifying and quantifying Vibrio species in marine and estuarine water samples is complex because identification errors may occur when using molecular methods that lack sufficient resolution.
Researchers have recently developed a standardized workflow for analyzing DNA methylation in individual cells. The protocol combines an improved laboratory procedure with an automated data analysis tool, making it easier to study differences between cells. Published in Nature Protocols, the study was led by researchers from the Institute of Health and Medical Technology at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences.
For a comprehensive understanding of the content of millions of Arabic manuscripts held in libraries around the world, it is crucial for scholars to first examine what their marginalia reveal, according to a new study published in the Journal of Islamic Thought and Civilization.
To guard proprietary know-how, many firms separate their inventors into independent groups so that no single employee sees too much of the organization's knowledge. New research published in Strategic Management Journal finds that when U.S. states strengthened trade secret law, high-tech firms relied less on this kind of compartmentalization and connected their inventors more broadly—and the inventions that followed had greater technological impact.
Researchers from ICMAB-CSIC, the Politecnico di Milano and Université de Liège have adapted a direct laser writing technique that allows them to "draw" superconducting properties in a material. The result is a new way to locally program the behavior of a superconductor, tuning it from a fully superconducting state to an insulating one with extraordinary precision.
Polyfluoroalkyl substances (PFAS) are known as "forever chemicals" because of the impact they make on the environment and human bodies. Much of modern manufacturing relies on these substances for safe packaging, fire protection and waterproof coatings.
Veterinarians often have limited access to one of the most effective tools for controlling life-threatening bleeding complications in dogs: platelets.
Faculty and university staff members report being bullied in two ways: by their colleagues and supervisors, and by their students over grades, according to an international study I conducted with colleagues Zahra Moradi and Deborah Circo.
Dialing up the power on electricity-driven chemical reactions doesn't guarantee that they'll be more efficient, suggests a new study, a finding that gets researchers closer to creating the ideal conditions for sustainable chemical manufacturing.
