Published Temperature, drought influencing movement of Plains bison
(via sciencedaily.com) Original source Temperature and severe drought can drive movement among herds of Plains bison, says a recent study. The team's GPS-backed data suggests that conserving the once-endangered species could depend on accounting for the climate extremes that Plains bison will likely encounter moving forward.
Published Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction
(via sciencedaily.com) Original source Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.
Published New discovery stops bacterial virus contamination
(via sciencedaily.com) Original source A new discovery could help stop bacteria being contaminated with viruses, reducing disruption and decreasing costs in industry and research.
Published Tracking a new path to octopus and squid sensing capabilities
(via sciencedaily.com) Original source Research has traced the evolutionary adaptations of octopus and squid sensing capabilities. The researchers describe for the first time the structure of an octopus chemotactile receptor, which octopus arms use for taste-by-touch exploration of the seafloor.
Published Software to untangle genetic factors linked to shared characteristics among different species
(via sciencedaily.com) Original source Scientists have developed a software package to help answer key questions about genetic factors associated with shared characteristics among different species.
Published Scientists develop new way to measure wind
(via sciencedaily.com) Original source Atmospheric scientists have developed an algorithm that uses data from water vapor movements to measure wind. This could help predict extreme events like hurricanes.
Published Microwaves advance solar-cell production and recycling
(via sciencedaily.com) Original source New technology advances solar-cell production and recycling. New microwave technology will improve the manufacture of solar cells and make them easier to recycle.
Published Nature-based management is making rivers more resilient
(via sciencedaily.com) Original source Nature-based management is making rivers more resilient. New research shows progress in Australia towards United Nations goals, making rivers more able to recover from flood, drought and other impacts. In July 2022, the 120-kilometre Wollombi Brook, which flows north into the Hunter Valley in New South Wales, suffered one of its biggest floods on record. And it held up remarkably well, says Professor Kirstie Fryirs of the School of Natural Sciences at Macquarie University. 'Yes, there was widespread inundation, but the flood waters were slower and the vegetation prevented large scale erosion and sediment movement. 'All the hard work that a very active community put into nature-based rehabilitation for more than 20 years, such as continuous streamside revegetation, played a role in this outcome.' It is one of the best examples in Australia of sustainable environmental restoration in the management of rivers, she says
Published How a virus causes chromosomal breakage, leading to cancer
(via sciencedaily.com) Original source Researchers describe how the Epstein-Barr virus exploits genomic weaknesses to cause cancer while reducing the body's ability to suppress it.
Published Kombucha to kimchi: Which fermented foods are best for your brain?
(via sciencedaily.com) Original source The consumption of fermented products is on the rise, and drinks like kombucha and kefir have gone viral in their popularity. But is there more to this than consumers searching for natural and healthy foods?
Published Air pollution is not just a human problem -- it's also changing the gut of British bumblebees
(via sciencedaily.com) Original source Human activity is contributing to pollution that is affecting our health. According to WHO estimates, atmospheric air pollution is estimated to cause 4.2 million premature deaths worldwide per year. Scientists and the public alike are well aware of how human activity and pollution is affecting our heath, but new research has identified how bumblebees may be caught in the crossfire.
Published Why orchid bees concoct their own fragrance
(via sciencedaily.com) Original source The reason why male bees collect scents in pockets on their hind legs remained a mystery for a long time. As an attractant? As a wedding gift? To show off to other males? Researchers have now figured it out.
Published Gentle method allows for eco-friendly recycling of solar cells
(via sciencedaily.com) Original source By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells.
Published Study reveals how pollinators cope with plant toxins
(via sciencedaily.com) Original source Pollinators such as honeybees produce special enzymes that detoxify defence chemicals produced by plants, new research shows.
Published Scientists create high-efficiency sustainable solar cells for IoT devices with AI-powered energy management
(via sciencedaily.com) Original source Researchers have created environmentally-friendly, high-efficiency photovoltaic cells that harness ambient light to power internet of Things (IoT) devices.
Published Where did the first sugars come from?
(via sciencedaily.com) Original source Origin-of-life chemists propose that glyoxylate could have been the original source of sugars on the 'prebiotic' Earth
Published New look at climate data shows substantially wetter rain and snow days ahead
(via sciencedaily.com) Original source A new look at climate data shows that, by the end of the century, the heaviest days of rain and snowfall across much of North America will likely release 20 to 30 percent more moisture than they do now. Much of the increased precipitation will occur in winter, potentially exacerbating flooding in regions such as the upper Midwest and the west coast. Researchers also found that heavy precipitation days historically experienced once in a century will become more frequent -- as often as once every 30 or 40 years in the Pacific Northwest and southeastern United States.
Published Chemists redesign biological PHAs, 'dream' biodegradable plastics
(via sciencedaily.com) Original source They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
Published Hairs that help fish feel -- and humans hear
(via sciencedaily.com) Original source Scientists are reporting a discovery about unexpected asymmetry on the hair cells of zebrafish that allow them to detect movement with greater sensitivity from the back than the front.
Published Wildfires and animal biodiversity
(via sciencedaily.com) Original source Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.
