Published Global natural history initiative builds groundbreaking database to address 21st century challenges
(via sciencedaily.com) A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Towards reducing biodiversity loss in fragmented habitats
(via sciencedaily.com) By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Published Semiconductor lattice marries electrons and magnetic moments
(via sciencedaily.com) A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published Ultra-lightweight multifunctional space skin created to withstand extreme conditions in space
(via sciencedaily.com) A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new study.
Published Batteries: Passivation layer mystery solved
(via sciencedaily.com) In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
Published 'Inkable' nanomaterial promises big benefits for bendable electronics
(via sciencedaily.com) An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Douglas-fir in Klamath Mountains are in 'decline spiral'
(via sciencedaily.com) Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published 'Fishing' for biomarkers
(via sciencedaily.com) Researchers have devised a tiny, nano-sized sensor capable of detecting protein biomarkers in a sample at single-molecule precision. Fittingly coined as 'hook and bait,' a tiny protein binder fuses to a small hole created in the membrane of a cell -- known as a nanopore -- which allows ionic solution to flow through it. When the sensor recognizes a targeted molecule, the ionic flow changes. This change in flow serves as the signal from the sensor that the biomarker has been found.
Published Coffee plantations limit birds' diets
(via sciencedaily.com) A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published How do we make farming better for the planet? Ask women
(via sciencedaily.com) A study used video games to test ways of balancing agriculture and conservation -- and found getting more women involved in decision-making may boost productivity and the planet's health.
Published Nanotechnology could treat lymphedema
(via sciencedaily.com) When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Researchers have now developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.
Published Mind-control robots a reality?
(via sciencedaily.com) Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published An elegant new orchid hiding in plain sight
(via sciencedaily.com) It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, botanists recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on balconies. This research suggests that other new species may be hiding in common places.
Published Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
(via sciencedaily.com) More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.
Published New study counts the environmental cost of managing Japanese knotweed
(via sciencedaily.com) New research has looked at the long-term environmental impact of different methods to control Japanese knotweed. Different ways of trying to control the invasive species have developed over the years but now, as sustainability becomes increasingly important, understanding the effect of these management methods is vital.This new study examines at the entire life cycle and long-term impacts of different management approaches.
Published How can we tackle the biggest challenges? Ask a plant
(via sciencedaily.com) Without plants, we'd have no air to breathe or food to eat, yet plant science lingers in the shadowy wings while other fields take center stage. With the goal of shining the spotlight on plants, a new study presents the field's top 100 most pressing questions for research to address the greatest challenges facing humanity.
