Strong European backing for Ukraine leaves 'little space' for exploitation of pro-Russian politics, study shows Strong support for Ukraine means there is "little space" for European politicians to exploit pro-Russia foreign policy messages, a new study shows. Researchers have found widespread backing for Ukraine across the continent, and for policies that help the nation, such as imposing sanctions on Russia. /news/2024-01-strong-european-ukraine-space-exploitation.html Political science Wed, 31 Jan 2024 17:14:03 EST news625943641 Multi-regional observations and validation of the M₃ ocean tide The lunar terdiurnal ocean tide has a period of approximately 8.2804 hours, and theoretically has a small amplitude. Its largest equilibrium action term is just 2.56 mm, generally considered to have little impact on shipping or other maritime activities. Thus, it has not received much attention in previous studies, and understanding of the M3 tide's characteristics in various global regions is extremely limited. /news/2023-10-multi-regional-validation-ocean-tide.html Earth Sciences Environment Wed, 11 Oct 2023 16:31:04 EDT news616260662 Faith primary schools admitting fewer children with special educational needs, study finds Faith primary schools are admitting fewer children with special educational needs and disabilities (SEND) than local authority community primaries, according to new research from the London School of Economics and Political Science (LSE). /news/2023-09-faith-primary-schools-children-special.html Education Sun, 01 Oct 2023 19:00:01 EDT news615197410 Study finds more Texas owls are testing positive for rat poisons New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR)—blood thinning rat poisons—in their systems.

In fact, complexity seems to be baked into our personality structure. In a widely cited paper, social psychologists Marilynn Brewer & Wendy Gardner theorized not one but three dimensions of identity: individual (who we innately feel we are), relational (how we perceive ourselves as part of a dyad, i.e., in relation to a specific person) and collective (the sense of self we derive from being part of a larger group). /news/2022-12-magic-workplace-pairings.html Economics & Business Tue, 13 Dec 2022 16:30:12 EST news590171404 Molecular makeover makes wimpy antibody a SARS-CoV-2 tackler Like the Roadrunner outwitting Wile E.

From landers on the moon to rovers on Mars and more, robots are the perfect candidates for space exploration: they can bear extreme environments while consistently repeating the same tasks in exactly the same way without tiring. Like robots on Earth, they can accomplish both dangerous and mundane jobs, from space walks to polishing a spacecraft's surface. With space missions increasing in number and expanding in scientific scope, requiring more equipment, there's a need for a lightweight robotic arm that can manipulate in environments difficult for humans. /news/2021-12-lightweight-space-robot-precise.html Space Exploration Fri, 03 Dec 2021 13:40:45 EST news557761230 Attitude toward diversity contributes to helping refugees become productive members of a host nation, study finds John Schaubroeck, a professor of management at the University of Missouri, believes hiring refugees can boost the economies of host countries.

It is therefore important to obtain high-resolution imaging of these moiré lattices and superstructures to understand the emerging physics. In a new report now published in Science Advances, Kyunghoon Lee and a team of scientists report the imaging process to view moiré lattices and superstructures in graphene-based samples under ambient conditions using scanning microwave impedance microscopy with ultrahigh-resolution implementation. While the probe tip of the device maintained a gross radius of 100 nm, the research team achieved a spatial resolution better than 5 nm. This setup allowed direct visualization of moiré lattices and the composite super-moiré. The researchers also showed the artificial synthesis of new superstructures arising from the interplay between diverse layers. /news/2020-12-dimensional-heterostructures-layers-slightly-lattice.html Nanophysics Nanomaterials Tue, 22 Dec 2020 12:50:02 EST news527862180 Resolving spatial and energetic distributions of trap states in metal halide perovskite solar cells In a new report published on Science, Zhenyi Ni and a research team in applied physical sciences, mechanical and materials engineering and computer and energy engineering in the U.S. profiled spatial and energetic distributions of trap states or defects in metal halide perovskite single-crystalline polycrystalline solar cells. The researchers credited the photovoltaic performance of metal halide perovskites (MHPs) to their high optical absorption coefficient, carrier mobility, long charge-diffusion length and small Urbach energy (representing disorder in the system). Theoretical studies have demonstrated the possibility of forming deep charge traps at the material surface due to low formation energy, structural defects and grain boundaries of perovskites to guide the development of passivation techniques (loss of chemical reactivity) in perovskite solar cells. Charge trap states play an important role during the degradation of perovskite solar cells and other devices. Understanding the distribution of trap states in their space and energy can clarify the impact of charge traps (defects) on charge transport in perovskite materials and devices for their optimal performance. /news/2020-03-spatial-energetic-states-metal-halide.html Condensed Matter Mon, 30 Mar 2020 10:23:38 EDT news504782610 Electrical power generation from moderate-temperature radiative thermal sources Moderate-temperature thermal sources often radiate waste heat as a by-product of mechanical work, chemical or nuclear reactions, or information processing. In a new report in Science, Paul S. Davids and a research team at the Sandia National Laboratory in the U.S., demonstrated the conversion of thermal radiation into electrical power. For this, they used a bipolar grating-coupled complimentary metal-oxide-silicon (CMOS) tunnel diode. Using a two-step photon-assisted tunneling charge pumping mechanism, the team separated the charge carriers in pn junction wells to develop a large, open-circuit voltage across a load. The scientists experimentally showed electrical power generation from a broadband blackbody thermal source with converted power densities of 27 to 61 µW/cm2 for thermal sources between 250 degrees C to 400 degrees C. The demonstrated scalable and efficient conversion of radiated waste heat into electrical power can be used to reduce energy consumption—in order to power electronics and sensors. /news/2020-03-electrical-power-moderate-temperature-radiative-thermal.html General Âé¶¹ÒùÔºics Tue, 10 Mar 2020 10:11:40 EDT news503053896 Modelling reveals dynamics of climate change, urbanization and heat-mitigating technologies The near-term future of Earth is one of a warming planet, as urban expansion and greenhouse gas emissions stoke the effects of climate change.

The 60 percent drop in their population since 2001 has put them on the endangered species list by the International Union for Conservation of Nature. In some South African colonies, the drop in population has been as high as 80 percent.
