Published Plant-based plastic releases nine times less microplastics than conventional plastic
(via sciencedaily.com) Original source A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.
Published AI helps to detect invasive Asian hornets
(via sciencedaily.com) Original source Artificial Intelligence can be used to detect invasive Asian hornets and raise the alarm, new research shows.
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 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 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 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 These plants evolved in Florida millions of years ago: They may be gone in decades
(via sciencedaily.com) Original source Scrub mints are among the most endangered plants you've probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality.
Published When did the chicken cross the road? New evidence from Central Asia
(via sciencedaily.com) Original source An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.
Published Older trees help to protect an endangered species
(via sciencedaily.com) Original source The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.
Published Biofilm-resistant glass for marine environments
(via sciencedaily.com) Original source Engineers have created ultraviolet (UV) rays-emitting glass that can reduce 98% of biofilm from growing on surfaces in underwater environments.
Published Scientists link certain gut bacteria to lower heart disease risk
(via sciencedaily.com) Original source Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers has found that microbes in the gut may affect cardiovascular disease as well. The team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
Published We've had bird evolution all wrong
(via sciencedaily.com) Original source Genomic anamolies dating back to the time of the dinosaurs misled scientists about the evolutionary history of birds.
Published New method reveals hidden activity of life below ground
(via sciencedaily.com) Original source Researchers have refined an innovative method for measuring the activity level of microbes and linking that to their individual genetic code, providing new insights into the microbial communities that thrive in extreme environments.
