All plastic waste could become new, high-quality plastic through advanced steam cracking
Fri, 18 Oct 2019 11:21:42 EDT
A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics - of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.
Stranded whales detected from space
Thu, 17 Oct 2019 14:11:14 EDT
A new technique for analysing satellite images may help scientists detect and count stranded whales from space. Researchers tested a new detection method using Very High Resolution (VHR) satellite images of the biggest mass stranding of baleen whales yet recorded. It is hoped that in the future the technique will lead to real-time information as stranding events happen.
Industrial melanism linked to same gene in 3 moth species
Thu, 17 Oct 2019 13:14:36 EDT
The rise of dark forms of many species of moth in heavily polluted areas of 19th and 20th century Britain, known as industrial melanism, was a highly visible response to environmental change. But did the different species rely on the same gene to adapt? New research by the University of Liverpool reveals that three species of moth, including the famous peppered moth, indeed did.
Breaking water molecules apart to generate clean fuel: Investigating a promising material
Thu, 17 Oct 2019 10:12:29 EDT
Scientists investigated a material that uses sunlight for splitting water molecules (H2O) to obtain dihydrogen (H2). Since dihydrogen can be used as clean fuel, this study provides relevant insight for researchers dealing with clean energy generation.
Are we underestimating the benefits of investing in renewable energy?
Wed, 16 Oct 2019 09:49:15 EDT
Scientists have estimated the emissions intensity of carbon dioxide and other air pollutants from a major electricity distributor and highlighted key consequences - essential information for policymakers shaping decisions to reduce electricity system emissions.
Accelerating global agricultural productivity growth is critical
Wed, 16 Oct 2019 07:47:50 EDT
The 2019 Global Agricultural Productivity Report, shows agricultural productivity growth -- increasing output of crops and livestock with existing or fewer inputs -- is growing globally at an average annual rate of 1.63%.
Airborne chemicals instantly identified using new technology
Tue, 15 Oct 2019 17:15:56 EDT
Scientists have developed a device that can identify a wide range of airborne gases and chemicals instantly.
Last year's extreme snowfall wiped out breeding of Arctic animals and plants
Tue, 15 Oct 2019 17:15:50 EDT
In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.
The makeup of mariculture: Global trends in seafood farming
Tue, 15 Oct 2019 11:33:20 EDT
The process of farming seafood in the ocean, known as mariculture, is a growing trend yet little is known about the trajectories of its development. That's why a team of researchers set out to shed some light on the industry.
Achieving a safe and just future for the ocean economy
Tue, 15 Oct 2019 09:22:38 EDT
much attention has been given to the growth of the 'Blue Economy' -- a term which refers to the sustainable use of ocean and marine resources for economic growth, jobs, and improved livelihoods. Ocean resources are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. Ensuring that socially equitable and sustainable development occurs should be the mandate of governments and industry, maintain an international group of researchers, led by UBC.
Lakes worldwide are experiencing more severe algal blooms
Mon, 14 Oct 2019 11:17:46 EDT
The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Researchers used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents.
Evolutionary history of oaks
Mon, 14 Oct 2019 11:17:26 EDT
Oaks have a complex evolutionary history that has long eluded scientists. New research, however, provides the most detailed account to date of the evolution of oaks, recovering the 56-million-year history that has made the oaks one of the most diverse, abundant and important woody plant groups to the ecology and economy of the northern hemisphere.
CO2 emissions cause lost labor productivity
Fri, 11 Oct 2019 13:18:56 EDT
Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted.
New material captures carbon dioxide and converts it into useful chemicals
Fri, 11 Oct 2019 11:22:31 EDT
The captured CO2 can be converted into useful organic materials.
New tool visualizes nature's benefits worldwide
Thu, 10 Oct 2019 14:21:09 EDT
The researchers set out to understand where nature contributes the most to people and how many people may be affected by future changes. By 2050, up to 5 billion people could be at higher risk of water pollution, coastal storms and under-pollinated crops.
