Published WhaleVis turns more than a century of whaling data into an interactive map



A team has created an interactive dashboard called WhaleVis, which lets users map data on global whale catches and whaling routes from 1880 to 1986. Scientists can compare this historical data and its trends with current information to better understand whale populations over time.
Published Climate change effects hit marine ecosystems in multiple waves, according to marine ecologists



A new approach to examining the effects of climate change on marine ecosystems may provide a more accurate understanding of climate change responses -- and predictions for future consequences -- according to a new article. The paper highlights the interplay between the trend of climate warming and the fluctuations in local temperature. These two properties cause atypically warm events such as marine heatwaves to occur with increasing frequency and magnitude.
Published Ice cores from Earth's highest tropical peak provide insight into climate variability



A new study examines ice cores from the summit of the highest tropical mountain in the world, and finds unique insight into the climate record of the Amazon Basin over the last six decades.
Published Clearing mangroves makes 'muddification' worse



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



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 Roaming seabirds need ocean-wide protection



Seabirds roam far and wide in the Indian Ocean -- so they need ocean-wide protection, new research shows.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers



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



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...



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



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



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 Keep it secret: Cloud data storage security approach taps quantum physics



Distributed cloud storage is a hot topic for security researchers, and a team is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage solution.
Published Faster Arctic warming hastens 2C rise by eight years



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



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



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



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



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



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



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 Barnacle bends shape to fend off warm-water sea snails on the move



Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
