Published Discovery could end global amphibian pandemic
(via sciencedaily.com)
Original source 
A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians.
Published Plastic-free vegan leather that dyes itself grown from bacteria
(via sciencedaily.com)
Original source 
Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Published More social birds are more adventurous feeders
(via sciencedaily.com)
Original source 
A new study has found that birds that are more social are more likely to use novel sources of food.
Published Magnetic fields boost clean energy
(via sciencedaily.com)
Original source 
Researchers show that using magnetic fields can boost electrocatalysis for sustainable fuel production by enhancing the movement of the reactants, which improves the efficiency of energy-related reactions.
Published New discovery unravels malaria invasion mechanism
(via sciencedaily.com)
Original source 
A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study reveals the role of a sugar called sialic acid in this invasion process. The findings have major implications for malaria vaccine and drug development.
Published Testing environmental water to monitor COVID-19 spread in unsheltered encampments
(via sciencedaily.com)
Original source 
To better understand COVID-19's spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection. To fill this information gap, researchers tested flood-control waterways near unsheltered encampments, finding similar transmission patterns as in the broader community and identifying previously unseen viral mutations.
Published Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
(via sciencedaily.com)
Original source 
Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
Published Groundbreaking research in groundwater's role in ecosystem sustainability
(via sciencedaily.com)
Original source 
Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.
Published Are universities connected to local sustainability? A new study suggests yes...and no.
(via sciencedaily.com)
Original source 
A new study finds that universities scoring strongly on measures of sustainability are associated with innovation and economic growth in their surrounding communities. However, the study did not find similar connections between university sustainability performance and environmental sustainability in their home communities.
Published Intelligent liquid
(via sciencedaily.com)
Original source 
Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.
Published First view of centromere variation and evolution
(via sciencedaily.com)
Original source 
A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown scientists how greatly centromeres differ in size and structure.
Published Scientists further our understanding of how a foodborne bacterium can survive in food preparation environments
(via sciencedaily.com)
Original source 
Scientists have discovered that bacterial populations remain stable on factory floor despite cleaning efforts in ready-to-eat food production facilities.
Published A simple way to harvest more 'blue energy' from waves
(via sciencedaily.com)
Original source 
As any surfer will tell you, waves pack a powerful punch. Now, we are one step closer to capturing the energy behind the ocean's constant ebb and flow with an improved 'blue energy' harvesting device. Researchers report that simply repositioning the electrode -- from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force -- dramatically increased the amount of wave energy that could be harvested.
Published New step in tectonic squeeze that turns seafloor into mountains
(via sciencedaily.com)
Original source 
Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.
Published First results from BREAD experiment demonstrate a new approach to searching for dark matter
(via sciencedaily.com)
Original source 
One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.
Published Chicks show vision and touch linked at birth
(via sciencedaily.com)
Original source 
Study reveals that newly hatched chicks can instantly recognize objects with their vision, even if they've only ever experienced them by touch.
Published Elastocaloric cooling: Refrigerator cools by flexing artificial muscles
(via sciencedaily.com)
Original source 
There is room for just one small bottle in the world's first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype is groundbreaking: it shows that elastocalorics is becoming a viable solution for practical applications. This climate-friendly cooling and heating technology is far more energy-efficient and sustainable than current methods.
Published Last chance to record archaic Greek language 'heading for extinction'
(via sciencedaily.com)
Original source 
A new data crowdsourcing platform aims to preserve the sound of Romeyka, an endangered millennia-old variety of Greek. Experts consider the language to be a linguistic goldmine and a living bridge to the ancient world.
Published Sunrise to sunset, new window coating blocks heat -- not view
(via sciencedaily.com)
Original source 
Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.
Published A new estimate of U.S. soil organic carbon to improve Earth system models
(via sciencedaily.com)
Original source 
Emory environmentals scientist combined field-level data with machine-learning techniques to estimate soil organic carbon at the U.S. scale, another step toward providing more accurate baseline data to improve Earth system models for climate change.
