Published Accelerating the discovery of single-molecule magnets with deep learning
(via sciencedaily.com)
Original source 
Single-molecule magnets (SMMs) are exciting materials. In a recent breakthrough, researchers have used deep learning to predict SMMs from 20,000 metal complexes. The predictions were made solely based on the crystal structures of these metal complexes, thus eliminating the need for time-consuming experiments and complex simulations. As a result, this method is expected to accelerate the development of functional materials, especially for high-density memory and quantum computing devices.
Published Plastic recycling with a protein anchor
(via sciencedaily.com)
Original source 
Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. A research team has now introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent degradation. The catalyst consists of a specially constructed 'anchor peptide' that adheres to polystyrene surfaces and a cobalt complex that oxidizes polystyrene.
Published Unlocking the energetic secrets of collective animal movement: How group behavior reduces energy costs in fish
(via sciencedaily.com)
Original source 
Researchers questioned if coordinated group movements by animals moving through a fluid could reduce the energy cost of locomotion. By combining biomechanics and bioenergetics the researchers found not only a significant amount of energy conservation, but also identified the reduced energy use per tail beat.
Published Even very low levels of pesticide exposure can affect fish for generations
(via sciencedaily.com)
Original source 
Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.
Published Panama Canal expansion rewrites history of world's most ecologically diverse bats
(via sciencedaily.com)
Original source 
In a new study, paleontologists describe the oldest-known leaf-nosed bat fossils, which were found along the banks of the Panama Canal. They're also the oldest bat fossils from Central America, preserved 20-million years ago when Panama and the rest of North America were separated from southern landmass by a seaway at least 120 miles wide.
Published New non-toxic method for producing high-quality graphene oxide
(via sciencedaily.com)
Original source 
Researchers have found a new way to synthesize graphene oxide which has significantly fewer defects compared to materials produced by most common method. Similarly good graphene oxide could be synthesized previously only using rather dangerous method involving extremely toxic fuming nitric acid.
Published Artificial reefs help preserve coral reefs by shifting divers away from the natural ones, according to new long-term study of one in Eilat
(via sciencedaily.com)
Original source 
Divers are essentially tourists who love coral reefs and invest a lot of time and effort to watch them. Unfortunately, divers also cause damage to corals, often unintentionally, through disturbing and resuspending sand, touching them, hitting them with their equipment, and scaring fish away. Artificial reefs have been proposed as a means of diverting diving pressure from the natural reef to alternative sites, thus preserving both dive tourism and the coral reef.
Published Study reveals molecular mechanisms behind hibernation in mammals
(via sciencedaily.com)
Original source 
Researchers have characterized changes in the structure of motor proteins, called myosins, and energy consumption that occur during hibernation, highlighting key differences in large and small hibernators.
Published Could ultra-processed foods be the new 'silent' killer?
(via sciencedaily.com)
Original source 
Hundreds of novel ingredients never encountered by human physiology are now found in nearly 60 percent of the average adult's diet and nearly 70 percent of children's diets in the U.S. An emerging health hazard is the unprecedented consumption of these ultra-processed foods in the standard American diet. This may be the new 'silent' killer, as was unrecognized high blood pressure in previous decades. Physicians provide important insights in a battle where the entertainment industry, the food industry and public policy do not align with their patients' needs.
Published Nature's checkup: Surveying biodiversity with environmental DNA sequencing
(via sciencedaily.com)
Original source 
A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands -- the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan. With upwards of 70 % of trees and many animal species being endemic to the archipelago, the islands have been dubbed 'the Galapagos of the East', as they are valuable as both a biodiversity hotspot and a cradle of scientific discovery.
Published Spy-satellite images offer insights into historical ecosystem changes
(via sciencedaily.com)
Original source 
New study advocates the use of more than one million declassified images for ecology and conservation. The images can offer better insights into the historical changes of ecosystems, species populations or changes in human influences on the environment dating back to the 1960s. Collaboration between ecologists, conservationists, and remote sensing experts is necessary to explore the full potential of the data.
Published Scientists develop novel radiotracer for earlier detection of disease
(via sciencedaily.com)
Original source 
Scientists have developed a new radiotracer (called [18F]4-FDF) that can map how cells use fructose for energy.
Published Wildfires linked to surge in mental health-related emergency department visits
(via sciencedaily.com)
Original source 
A new studyshows wildfires lead to an increase of anxiety-related emergency department visits in the western United States, amplifying the concerning parallel trajectory of two escalating public health crises -- mental health and climate change.
Published Physically impaired primates find ways to modify their behaviors to compensate for their disabilities
(via sciencedaily.com)
Original source 
Primates show a remarkable ability to modify their behaviours to accommodate their physical disabilities and impairments, according to a new literature review. Whether the disabilities are the result of congenital malformations or injuries, many primate species exhibited behavioral flexibility and innovation to compensate for their disabilities. They also benefited from flexible and innovative behavior by their mothers early in life and from their peers within their population group as they aged.
Published Scientists may have cracked the 'aging process' in species
(via sciencedaily.com)
Original source 
Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'
Published Decline in microbial genetic richness in the western Arctic Ocean
(via sciencedaily.com)
Original source 
Researchers analyzed archival samples of bacteria and archaea populations taken from the Beaufort Sea, bordering northwest Canada and Alaska. The samples were collected between 2004 and 2012, a period that included two years -- 2007 and 2012 -- in which the sea ice coverage was historically low. The researchers looked at samples taken from three levels of water: the summer mixed layer, the upper Arctic water below it and the Pacific-origin water at the deepest level. The study examined the microbes' genetic composition using bioinformatics and statistical analysis across the nine-year time span. Using this data, the researchers were able to see how changing environmental conditions were influencing the organisms' structure and function.
Published Astronomers report oscillation of our giant, gaseous neighbor
(via sciencedaily.com)
Original source 
A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the galaxy we call home. Naming this astonishing new structure the Radcliffe Wave, the team now reports that the Radcliffe Wave not only looks like a wave, but also moves like one -- oscillating through space-time much like 'the wave' moving through a stadium full of fans.
Published Fresh meat: New biosensor accurately and efficiently determines meat freshness
(via sciencedaily.com)
Original source 
Despite the technological advances keeping meat fresh for as long as possible, certain aging processes are unavoidable. Adenosine triphosphate is a molecule produced by breathing and responsible for providing energy to cells. When an animal stops breathing, ATP synthesis also stops, and the existing molecules decompose into acid, diminishing first flavor and then safety. Hypoxanthine and xanthine are intermediate steps in this transition. Assessing their prevalence in meat indicates its freshness.
Published Ancient DNA reveals Down syndrome in past human societies
(via sciencedaily.com)
Original source
