Published Biologists uncover new species of tiger beetle: Eunota houstoniana
(via sciencedaily.com) Original source Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
Published Researchers find energy development and tree encroachment impact Wyoming pronghorn
(via sciencedaily.com) Original source While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
Published New method to measure entropy production on the nanoscale
(via sciencedaily.com) Original source Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser excited materials.
Published Silicon spikes take out 96% of virus particles
(via sciencedaily.com) Original source An international research team has designed and manufactured a virus-killing surface that could help control disease spread in hospitals, labs and other high-risk environments.
Published Micro-Lisa! Making a mark with novel nano-scale laser writing
(via sciencedaily.com) Original source High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests
(via sciencedaily.com) Original source When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.
Published 'Winners and losers' as global warming forces plants uphill
(via sciencedaily.com) Original source Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.
Published A self-cleaning wall paint
(via sciencedaily.com) Original source Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special titanium oxide nanoparticles have been developed that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards.
Published Quantum interference could lead to smaller, faster, and more energy-efficient transistors
(via sciencedaily.com) Original source Scientists made a single-molecule transistor using quantum interference to control electron flow. This new design offers high on/off ratio and stability, potentially leading to smaller, faster, and more energy-efficient devices. Quantum interference also improves the transistor's sensitivity to voltage changes, further boosting its efficiency.
Published Product that kills agricultural pests also deadly to native Pacific Northwest snail
(via sciencedaily.com) Original source A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.
Published Forest, stream habitats keep energy exchanges in balance, global team finds
(via sciencedaily.com) Original source Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.
Published In-situ observation of nanoscale heat propagation
(via sciencedaily.com) Original source A research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission electron microscope (STEM) capable of emitting a pulsed electron beam and a nanosized thermocouple -- a high-precision temperature measurement device.
Published Robotic metamaterial: An endless domino effect
(via sciencedaily.com) Original source If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.
Published Metamaterials and AI converge, igniting innovative breakthroughs
(via sciencedaily.com) Original source Scientists unveil next-generation research trends in metaphotonics platforms with AI.
Published Decoding the Easter Bunny -- an eastern Finnish brown hare to represent the standard for the species' genome
(via sciencedaily.com) Original source Biologists have published a chromosomally assembled reference genome for the European brown hare. The genome consists of 2.9 billion base pairs, which form 23 autosomal chromosomes, and X and Y sex chromosomes. The timing of the genome release is very appropriate as the brown hare also represents the original Easter Bunny familiar from European folklore.
Published Toxic metal particles can be present in cannabis vapes even before the first use, study finds
(via sciencedaily.com) Original source Though vapes have been heralded as a 'safer' way to consume either nicotine or cannabis, they present their own suite of risks that are being revealed through increasing regulation. Now, scientists have discovered that nano-sized toxic metal particles can be present in cannabis vaping liquids even before any heating occurs, and the effect is worse in illicit products.
Published Sustainable solution for wastewater polluted by dyes used in many industries
(via sciencedaily.com) Original source Water pollution from dyes used in textile, food, cosmetic and other manufacturing is a major ecological concern with industry and scientists seeking biocompatible and more sustainable alternatives to protect the environment. A new study has discovered a novel way to degrade and potentially remove toxic organic chemicals including azo dyes from wastewater, using a chemical photocatalysis process powered by ultraviolet light.
Published Bendable energy storage materials by cool science
(via sciencedaily.com) Original source Imaging being able to wear clothes that charge your gadgets just by wearing them. New research has brought us a step closer to achieving this reality.
