Published Novel bacterial proteins from seafloor shine light on climate and astrobiology
(via sciencedaily.com) Original source Researchers have unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.
Published New research reveals dynamic factors shaping biodiversity at small scales
(via sciencedaily.com) Original source Researchers studying arboreal ants in a Florida forest explore the fundamental question of how resource availability and competition shape biodiversity.
Published Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
(via sciencedaily.com) Original source A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star's death and explosion.
Published Strength is in this glass's DNA
(via sciencedaily.com) Original source Scientists were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight.
Published Study shows how a single neuron's parallel outputs can coordinate many aspects of behavior
(via sciencedaily.com) Original source In C. elegans worms, a single neuron named HSN uses multiple chemicals and connections to orchestrate egg-laying and locomotion over the course of several minutes.
Published How the heart starts beating
(via sciencedaily.com) Original source Researchers discover that heart cells in developing zebrafish start beating suddenly and all at once
Published Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years
(via sciencedaily.com) Original source Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.
Published Down goes antimatter! Gravity's effect on matter's elusive twin is revealed
(via sciencedaily.com) For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
Published Powering the quantum revolution: Quantum engines on the horizon
(via sciencedaily.com) Original source Scientists unveil exciting possibilities for the development of highly efficient quantum devices.
Published New proof for black hole spin
(via sciencedaily.com) Original source The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
Published Desalination system could produce freshwater that is cheaper than tap water
(via sciencedaily.com) Original source Researchers have designed a new solar desalination system that takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren't needed often, meaning the system could potentially produce drinking water at a rate and price that is cheaper than tap water.
Published Protecting lands slows biodiversity loss among vertebrates by five times
(via sciencedaily.com) Original source Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.
Published Milestone for novel atomic clock
(via sciencedaily.com) Original source An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years -- that is about a thousand times more precise than the current standard atomic clock based on caesium.
Published Researchers discover disease-causing stem cells in lungs of cystic fibrosis patients
(via sciencedaily.com) Original source Experts in cloning and stem cell science are reporting that five lung stem cell variants dominate the lungs of patients with advanced cystic fibrosis, and that these variants drive key aspects of CF pathology including inflammation, fibrosis and mucin secretion.
Published Microplastics are found in cave water and sediment
(via sciencedaily.com) Original source Researchers report finding high concentrations of microplastics present in a Missouri cave system that had been closed to human visitors for 30 years.
Published Tree rings reveal a new kind of earthquake threat to the Pacific Northwest, US
(via sciencedaily.com) Original source Tree rings reveal a new kind of earthquake threat to the Pacific Northwest. These findings could have implications for seismic preparedness measures in the region.
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 to save plants from climate change? Just ask them
(via sciencedaily.com) Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.
Published A close-up of biological nanomachines: Researchers take a deep look at peroxisomal processes
(via sciencedaily.com) The cell organelles known as 'peroxisomes' dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The 'Pex' group of proteins (peroxisomes biogenesis factors) keep these 'detox units' functioning properly -- and now researchers have shown, at the atomic level, how these highly complex processes proceed.
Published Making a femtosecond laser out of glass
(via sciencedaily.com) Original source Scientists show that it is possible to make a femtosecond laser that fits in the palm of one's hand using a glass substrate.
