Published California supervolcano is cooling off but may still cause quakes
(via sciencedaily.com)
Original source 
New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com)
Original source 
Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com)
Original source 
Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
Published Going rogue: Scientists apply giant wave mechanics on a nanometric scale
(via sciencedaily.com)
Original source 
Researchers have shown how the principles of rogue waves -- huge 30-meter waves that arise unexpectedly in the ocean -- can be applied on a nano scale, with dozens of applications from medicine to manufacturing.
Published Drought conditions expose rivers to hotter water temperatures
(via sciencedaily.com)
Original source 
A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published Ancient diamonds shine light on the evolution of Earth
(via sciencedaily.com)
Original source 
Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how supercontinents such as Gondwana were formed, stabilised, and how they move around the planet.
Published Study elucidates evolution of mosquitoes and their hosts
(via sciencedaily.com)
Original source 
Study creates a mosquito family tree to better understand disease transmission and host choice.
Published Protecting polar bears: New and improved radar technology
(via sciencedaily.com)
Original source 
Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers hope that improving detection tools to locate dens -- which are nearly invisible and buried under snow -- will help efforts to protect mother polar bears and their cubs.
Published Robotic prosthetic ankles improve 'natural' movement, stability
(via sciencedaily.com)
Original source 
Robotic prosthetic ankles that are controlled by nerve impulses allow amputees to move more 'naturally,' improving their stability, according to a new study.
Published The encounter between Neanderthals and Sapiens as told by their genomes
(via sciencedaily.com)
Original source 
About 40,000 years ago, Neanderthals, who had lived for hundreds of thousands of years in the western part of the Eurasian continent, gave way to Homo sapiens, who had arrived from Africa. This replacement was not sudden, and the two species coexisted for a few millennia, resulting in the integration of Neanderthal DNA into the genome of Sapiens. Researchers have analyzed the distribution of the portion of DNA inherited from Neanderthals in the genomes of humans (Homo sapiens) over the last 40,000 years. These statistical analyses revealed subtle variations in time and geographical space.
Published Choosing exoskeleton settings like a radio station
(via sciencedaily.com)
Original source 
Taking inspiration from music streaming services, a team of engineers has designed the simplest way for users to program their own exoskeleton assistance settings.
Published Milestone: Miniature particle accelerator works
(via sciencedaily.com)
Original source 
Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky. Until now, no substantial energy gains were demonstrated. In other words, it has not been shown that electrons really have increased in speed significantly. Two teams of laser physicists have just succeeded in demonstrating a nanophotonic electron accelerator.
Published Single vaccine protects against three deadly strains of coronavirus
(via sciencedaily.com)
Original source 
A vaccine designed to protect against three different deadly coronaviruses shows success in mouse studies, demonstrating the viability of a pan-coronavirus vaccine developed by researchers at the Duke Human Vaccine Institute.
Published Scientists uncover new way viruses fight back against bacteria
(via sciencedaily.com)
Original source 
A microscopic discovery will not only enable scientists to understand the microbial world around us but could also provide a new way to control CRISPR-Cas biotechnologies.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors
(via sciencedaily.com)
Original source 
The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
Published Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
(via sciencedaily.com)
Original source 
According to researchers, there is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability of plant residues are not included. According to the researchers, this leads to misleading inventories, which also misrepresents possible mitigation measures.
Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com)
Original source 
The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published Four eating behavior patterns of children
(via sciencedaily.com)
Original source 
Children fall broadly into four eating categories, according to new research, and parents feed their children differently depending on those categories.
Published Superlensing without a super lens: Physicists boost microscopes beyond limits
(via sciencedaily.com)
Original source 
Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, breaking through the diffraction limit by a factor of nearly four times. The key to their success was to remove the super lens altogether.
Published Using computer algorithms to find molecular adaptations to improve COVID-19 drugs
(via sciencedaily.com)
Original source 
A new study focuses on using computer algorithms to generate adaptations to molecules in compounds for existing and potential medications that can improve those molecules' ability to bind to the main protease, a protein-based enzyme that breaks down complex proteins, in SARS-CoV-2, the virus that causes COVID-19.
