Published DNA becomes our 'hands' to construct advanced nanoparticle materials



A new paper describes a significant leap forward in assembling polyhedral nanoparticles. The researchers introduce and demonstrate the power of a novel synthetic strategy that expands possibilities in metamaterial design. These are the unusual materials that underpin 'invisibility cloaks' and ultrahigh-speed optical computing systems.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird



The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Chemical synthesis: New strategy for skeletal editing on pyridines



A team has introduced a strategy for converting carbon-nitrogen atom pairs in a frequently used ring-shaped compound into carbon-carbon atom pairs. The method has potential in the quest for active ingredients for new drugs, for example.
Published Why animals shrink over time explained with new evolution theory



The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published Unlocking the secrets of quasicrystal magnetism: Revealing a novel magnetic phase diagram



Non-Heisenberg-type approximant crystals have many interesting properties and are intriguing for researchers of condensed matter physics. However, their magnetic phase diagrams, which are crucial for realizing their potential, remain completely unknown. Now, a team of researchers has constructed the magnetic phase diagram of a non-Heisenberg Tsai-type 1/1 gold-gallium-terbium approximant crystal. This development marks a significant step forward for quasicrystal research and for the realization of magnetic refrigerators and spintronic devices.
Published Efficiently moving urea out of polluted water is coming to reality



Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and revolutionizing the water-energy nexus.
Published The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance



Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.
Published Chemists create a 2D heavy fermion



Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.
Published Higher measurement accuracy opens new window to the quantum world



A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
Published Let it glow: Scientists develop new approach to detect 'forever chemicals' in water



Researchers have created a new way to detect 'forever chemical' pollution in water, via a luminescent sensor.
Published New insight into frictionless surfaces is slippery slope to energy-efficient technology



Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving parts.
Published Study reveals a reaction at the heart of many renewable energy technologies



Chemists have mapped how proton-coupled electron transfers happen at the surface of an electrode. Their results could help researchers design more efficient fuel cells, batteries, or other energy technologies.
Published Climate change threatens global forest carbon sequestration, study finds



Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Squishy, metal-free magnets to power robots and guide medical implants



'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based, magnetic molecules are chemically bonded to the molecular network of a gel, creating a flexible, long-lived magnet for soft robotics.
Published Cheap substitute for expensive metal in an industrially common chemical reaction



Researchers have helped minimize the cost of an important class of chemical transformations: converting nitriles into primary amines. Their experimental protocol uses a cheap nickel catalyst instead of an expensive noble metal, is convenient to conduct, and works for a broad range of starting materials. This work is an important advance in sustainable chemistry that might help lower the cost of producing nylon and many other everyday products.
Published Physicists identify overlooked uncertainty in real-world experiments



The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, researchers argue that uncertainty in the thermodynamic parameters themselves -- built into equations that govern the energetic behavior of the system -- may also influence the outcome of an experiment.
Published Key moment in the evolution of life on Earth captured in fossils



New research has precisely dated some of the oldest fossils of complex multicellular life in the world, helping to track a pivotal moment in the history of Earth when the seas began teeming with new lifeforms -- after four billion years of containing only single-celled microbes.
