Published Clearing mangroves makes 'muddification' worse
(via sciencedaily.com) Original source Clearing mangroves to stop estuaries getting clogged with mud actually makes the problem worse, new research shows.
Published Climate engineering could slow Antarctic ice loss, study suggests
(via sciencedaily.com) Original source A study reports that scattering sunlight-reflecting particles in the atmosphere -- a theoretical form of climate engineering known as 'stratospheric aerosol injection' -- has potential to slow rapid ice melt in Western Antarctica.
Published Printed robots with bones, ligaments, and tendons
(via sciencedaily.com) Original source For the first time, researchers have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique. The new technology makes it possible to 3D print special plastics with elastic qualities in one go. This opens up completely new possibilities for the production of soft robotic structures.
Published Roaming seabirds need ocean-wide protection
(via sciencedaily.com) Original source Seabirds roam far and wide in the Indian Ocean -- so they need ocean-wide protection, new research shows.
Published This 3D printer can watch itself fabricate objects
(via sciencedaily.com) Original source Engineers have developed a high-throughput, multimaterial 3D inkjet printer that uses computer vision to rapidly and automatically control the amount of material being deposited during the printing process in real time. This enables the use of a wide range of materials for fabrication.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Melting ice falling snow: Sea ice declines enhance snowfall over West Antarctica
(via sciencedaily.com) Original source As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise.
Published Shark fear: Just when you thought it was safe to get back in the water...
(via sciencedaily.com) Original source It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published Study sheds light on how Earth cycles fossil-carbon
(via sciencedaily.com) Original source Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.
Published Individual back training machine developed
(via sciencedaily.com) Original source 18 percent of reported sick leave relates to musculoskeletal ailments, in particular back-related disorders. The GyroTrainer is an intelligent training device that resembles a balance board. It uses artificial intelligence to adjust the difficulty level to the individual patient's current ability.
Published Faster Arctic warming hastens 2C rise by eight years
(via sciencedaily.com) Original source The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.
Published Ammonia for fertilizers without the giant carbon footprint
(via sciencedaily.com) Original source Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertilizer vital for crop-growing.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s
(via sciencedaily.com) Original source In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published A 'fish cartel' for Africa could benefit the countries, and their seas
(via sciencedaily.com) Original source Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, researchers say African fisheries would not just secure more competitive access fees, they could also protect their seas' biodiversity.
Published Endangered turtle population under threat as pollution may lead to excess of females being born
(via sciencedaily.com) Original source Researchers find exposure to heavy metals cadmium and antimony and certain organic contaminants, accumulated by the mother and transferred to her eggs, may cause embryos to be feminized in green sea turtles (Chelonia mydas), a species already at risk of extinction from a current lack of male hatchlings.
Published Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years
(via sciencedaily.com) Original source A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.
Published Scientists caution against a reliance on mechanical devices to clear water bodies of plastic
(via sciencedaily.com) Original source An international group of scientists has called for the United Nations Treaty on Plastic Pollution to focus more on measures to reduce the production and consumption of plastics and the prevention of future plastic waste, rather than on the unselective removal of waste already in the water.
Published Engineers are on a failure-finding mission
(via sciencedaily.com) Original source Engineers developed a technique to quickly identify a range of potential failures in a system before they are deployed in the real world.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
