Published Nuclear fusion, lithium and the tokamak: Adding just enough fuel to the fire
(via sciencedaily.com) Original source Building upon recent findings showing the promise of coating the inner surface of the vessel containing a fusion plasma in liquid lithium, researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. The research includes observations, numerical simulations and analysis from their experiments inside a fusion plasma vessel called the Lithium Tokamak Experiment-Beta (LTX- ). This is the first time such a level has been established for LTX- , and knowing it is a big step in their mission to prove lithium is the ideal choice for an inner-wall coating in a tokamak because it guides them toward the best practices for fueling their plasmas.
Published Understanding cattle grazing personalities may foster sustainable rangelands
(via sciencedaily.com) Original source New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Heat, cold extremes hold untapped potential for solar and wind energy
(via sciencedaily.com) Original source Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.
Published Combination of the climate crisis and continued deforestation may result in significant damage to the animal world
(via sciencedaily.com) Original source A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.
Published Biologists uncover new species of tiger beetle: Eunota houstoniana
(via sciencedaily.com) Original source Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
Published Researchers find energy development and tree encroachment impact Wyoming pronghorn
(via sciencedaily.com) Original source While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
Published In paleontology, correct names are keys to accurate study
(via sciencedaily.com) Original source When the skeletal remains of a giant ground sloth were first unearthed in 1796, the discovery marked one of the earliest paleontological finds in American history.
Published New roadmap to prevent pandemics centers on protecting biodiversity
(via sciencedaily.com) Original source An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Citizen scientists contribute vital information about 35 seahorse species
(via sciencedaily.com) Original source Thanks to diligent observers, seahorses, those enigmatic and charismatic fish, are not only being discovered in new habitats and expanded geographic ranges, they are also being found at new ocean depths. While their capacity for male pregnancy has long fascinated people, new information on sex ratio and pregnancy seasonality has been discovered.
Published Humans pass more viruses to other animals than we catch from them
(via sciencedaily.com) Original source Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.
Published Wild bird gestures 'after you'
(via sciencedaily.com) Original source A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published Revolutionizing hydrogen production: Economical and efficient solutions unveiled
(via sciencedaily.com) Original source Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.
Published Research uncovers a rare resin fossil find: A spider that aspires to be an ant
(via sciencedaily.com) Original source Spiders that disguise themselves as ants live in many locations around the globe but until now most had been able to avoid detection from fossil researchers as well as predators.
Published Species diversity promotes ecosystem stability
(via sciencedaily.com) Original source What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.
