Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
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 Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
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 New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Geoscientists shed a light on life's evolution 800 million years ago
(via sciencedaily.com) Is nitrate responsible for algae, flowers, and even your neighbors? A team of geoscientists have unearthed evidence that may indicate yes.
Published Copper artifacts unearth new cultural connections in southern Africa
(via sciencedaily.com) Chemical and isotopic analysis of artifacts from southern Africa called copper ingots reveals new cultural connections among people living in the region between the 5th and 20th centuries.
Published Sea ice will soon disappear from the Arctic during the summer months -- and it has happened before
(via sciencedaily.com) In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.
Published Human and ocean health impacts of ocean plastics
(via sciencedaily.com) Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.
Published 3000+ billion tons of ice lost from Antarctic Ice Sheet over 25 years
(via sciencedaily.com) Original source Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a 25-year?period.??
Published Defunding prevention and climate change drive rebound of malaria in Peru
(via sciencedaily.com) Malaria control programs in Amazonian Peru helped reduce the incidence of the deadly parasitic disease by 78 percent. That is, until the programs ceased to operate. Within four years of the programs being de-funded, malaria rates where right back where they started. The rebound was driven not only by the removal of prevention programs, but also by climate change. Average temperatures in Peru have risen a half-degree Centigrade in the last 20 years.
Published Genome research: Origin and evolution of vine
(via sciencedaily.com) Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.
Published Stressed out: Mapping the human footprint on coastal areas globally
(via sciencedaily.com) A global mapping project has revealed the major stressors placed upon global coastlines by human activity.
Published 3D radar scan provides clues about threats to iconic Alaskan glacier
(via sciencedaily.com) Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.
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 Rivers and streams in the Andean Cordillera are hot spots for greenhouse gases emissions
(via sciencedaily.com) Researchers show that rivers in the Andean mountains contribute 35% and 72% of riverine emissions of carbon dioxide (CO2 ) and methane (CH4 ) in the Amazon basin, the world's largest river.
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.
Published Where the sidewalk ends
(via sciencedaily.com) Most cities don't map their own pedestrian networks. Now, researchers have built the first open-source tool to let planners do just that. Researchers have built TILE2NET, an open-source tool that uses aerial imagery and image-recognition to create complete maps of sidewalks and crosswalks. The tool can help planners, policymakers, and urbanists who want to expand pedestrian infrastructure.
Published New study provides first comprehensive look at oxygen loss on coral reefs
(via sciencedaily.com) A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. The study captures the current state of hypoxia -- or low oxygen levels -- at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.
