Published What is it good for? Absolutely one thing: Luna moths use their tails solely for bat evasion
(via sciencedaily.com) Original source Scientists recently discovered that Luna moths use their long tails as decoys to throw bats off their trail. But their tails also make Luna moths might also make them stand out to potential mates and make them more conspicuous to lurking predators. A pair of complementary studies looked to see whether these colorful, bat-deflecting appendages might come with any additional costs or benefitt
Published Scientists show how we can anticipate rather than react to extinction in mammals
(via sciencedaily.com) Original source Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published Engineered plants produce sex perfume to trick pests and replace pesticides
(via sciencedaily.com) Original source Tobacco plants have been engineered to manufacture an alluring perfume of insect sex pheromones, which could be used to confuse would-be pests looking for love and reduce the need for harmful pesticides.
Published Here's how a worm's embryonic cells changed its development potential
(via sciencedaily.com) Original source Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.
Published Scientists discover a way Earth's atmosphere cleans itself
(via sciencedaily.com) Original source Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere.
Published Environmental impact reports hugely underestimate consequences for wildlife
(via sciencedaily.com) Original source Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Sierra squirrels find their niche amid a changing climate
(via sciencedaily.com) Original source A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published New pesticide exposure test developed to protect inexperienced cannabis farmers
(via sciencedaily.com) Original source Chemists created a more reliable, robust and efficient way to monitor pesticide exposure and help protect the health and safety of agricultural workers, especially for emerging sectors like the cannabis industry.
Published Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease
(via sciencedaily.com) Original source Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.
Published Air pollution may increase risk for dementia
(via sciencedaily.com) Original source Exposure to fine particulate air pollutants (PM2.5) may increase the risk of developing dementia, according to a new meta-analysis.
Published Gone for good? California's beetle-killed, carbon-storing pine forests may not come back
(via sciencedaily.com) Original source Ponderosa pine forests in the Sierra Nevada that were wiped out by western pine beetles during the 2012-2015 megadrought won't recover to pre-drought densities, reducing an important storehouse for atmospheric carbon.
Published Surprising science behind bumblebee superfood
(via sciencedaily.com) Original source It's the spines. New research shows that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81 -- 94% and markedly increases the production of queen bumble bees. The research provides much-needed food for thought in one of the most vexing problems facing biologists and ecologists: how to reverse the great die-off of the world's pollinators.
Published Lifting the veil on disease avoidance strategies in multiple animal species
(via sciencedaily.com) Original source A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species including the native common octopus and the invasive red-eared slider, which are both relevant to Japan.
Published Opening a new frontier: PdMo intermetallic catalyst for promoting CO2 utilization
(via sciencedaily.com) Original source A recently discovered catalyst, can convert carbon dioxide (CO2) into useful methanol at room temperature and low-pressure conditions. This novel compound, which is thermally and chemically stable in air, represents a new milestone in CO2 conversion via hydrogenation and could be key to slow down climate change.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes
(via sciencedaily.com) Original source Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published Was plate tectonics occurring when life first formed on Earth?
(via sciencedaily.com) Original source Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.
Published New insights into engineering climate-smart crops for the future
(via sciencedaily.com) Original source New research in the field of plant sciences has made significant advances towards understanding the underlying reasons behind why certain crops are better at generating more yield than others.
Published Scientists use computational modeling to design 'ultrastable' materials
(via sciencedaily.com) Original source Researchers developed a computational approach to predict which metal-organic framework (MOF) structures will be the most stable, and therefore the best candidates for applications such as capturing greenhouse gases.
Published Lab-grown fat could give cultured meat real flavor and texture
(via sciencedaily.com) Original source Researchers have successfully bulk-produced fat tissue in the lab that has a similar texture and make-up to naturally occurring fats from animals.
