Published Solving a sticky, life-threatening problem
(via sciencedaily.com) Original source Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs
(via sciencedaily.com) Original source Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published Wild Asian elephants display unique puzzle solving skills
(via sciencedaily.com) Original source A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Researchers dynamically tune friction in graphene
(via sciencedaily.com) Original source The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers.
Published 3D-printed plasmonic plastic enables large-scale optical sensor production
(via sciencedaily.com) Original source Researchers have developed plasmonic plastic -- a type of composite material with unique optical properties that can be 3D-printed. This research has now resulted in 3D-printed optical hydrogen sensors that could play an important role in the transition to green energy and industry.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife
(via sciencedaily.com) Original source Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.
Published Toxic formaldehyde's dual nature to be probed with new chemical tool
(via sciencedaily.com) Original source Newly developed ompounds aim to reveal the dual nature of formaldehyde, a chemical that is known to cause cancer but is also believed to play important roles in our biology.
Published Scientists unveil fire-safe fuel
(via sciencedaily.com) Original source Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
Published Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry
(via sciencedaily.com) Original source Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes. Scientists have now isolated one of these enzymes. When the enzyme was electronically branched on an electrode, they observed the conversion of CO2 to formate with perfect efficiency. This phenomenon will inspire new CO2-fixation systems because of its remarkable directionality and rates.
Published Accelerating sustainable semiconductors with 'multielement ink'
(via sciencedaily.com) Original source Scientists have demonstrated 'multielement ink' -- the first 'high-entropy' semiconductor that can be processed at low-temperature or room temperature. The new material could enable cost-effective and energy-efficient semiconductor manufacturing.
Published Why are killer whales harassing and killing porpoises without eating them?
(via sciencedaily.com) Original source For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Whales Around the World Play With Kelp Clumps
(via sciencedaily.com) Original source A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.
Published Separating molecules requires lots of energy. This new, heat-resistant membrane could change that
(via sciencedaily.com) Original source A research team has created a new, heat-resistant membrane that can withstand harsh environments -- high temperatures, high pressure and complex chemical solvents -- associated with industrial separation processes. It could eventually be used as a less energy intensive alternative to distillation and other industrial processes that separate molecules that ultimately serve as ingredients in medicine, chemicals and other products.
Published How organic solar cells could become significantly more efficient
(via sciencedaily.com) Original source The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
Published Crystallization as the driving force
(via sciencedaily.com) Scientists have successfully developed nanomaterials using a so-called bottom-up approach. They exploit the fact that crystals often grow in a specific direction during crystallization. These resulting nanostructures, which appear as 'worm-like and decorated rods,' could be used in various technological applications.
Published Copper-based catalysts efficiently turn carbon dioxide into methane
(via sciencedaily.com) Copper-based catalysts developed by materials scientists help speed up the rate of carbon dioxide-to-methane conversion.
Published Jellyfish, with no central brain, shown to learn from past experience
(via sciencedaily.com) Original source Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.
Published Unraveling the mysteries of glassy liquids
(via sciencedaily.com) Original source A collaborative study builds a novel theory to explain the puzzling collective behavior of glass-forming liquids at low temperatures, a phenomenon with widespread implications in fields like material science and biology.
Published Conversations with plants: Can we provide plants with advance warning of impending dangers?
(via sciencedaily.com) Original source Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.
Published This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage
(via sciencedaily.com) Original source Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.
