| What the rise of oxygen on early Earth tells us about life on other planets Posted: 31 Jan 2022 01:15 PM PST When did the Earth reach oxygen levels sufficient to support animal life? Researchers have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years. |
| Power at sea: Towards high-performance seawater batteries Posted: 31 Jan 2022 12:33 PM PST Despite the many potential applications of seawater batteries (SWBs), the limited performance of available materials has hindered their commercialization. To tackle this issue, scientists have developed a novel co-doped carbon material for the anode of SWBs. Their straightforward synthesis route and the high performance of the developed anode material will pave the way for the widespread adoption of SWBs, which are safer and less expensive than lithium-ion batteries. |
| The two types of climate coping and what they mean for your health Posted: 31 Jan 2022 12:32 PM PST When it comes to coping with climate change, there may be two types of people: those who take action to try to improve the environment and those who don't bother because they don't believe their actions will make a difference. Knowing who's who could help policymakers communicate more effectively about environmental issues, new research suggests. |
| Posted: 31 Jan 2022 12:32 PM PST A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered. |
| Midwestern beef production works just as well off pasture Posted: 31 Jan 2022 10:28 AM PST Beef producers in the upper Midwest know grazing land is in short supply. With more acres being developed or converted to cropland, producers who want to expand their cow-calf operations are looking for alternatives to traditional pasture management. New research shows cow-calf pairs can be managed in drylots throughout the summer grazing period with few negative consequences. |
| Widespread retreat and loss of marine-terminating glaciers in the northern hemisphere Posted: 31 Jan 2022 10:28 AM PST Researchers have mapped out all the glaciers that end in the ocean in the Northern Hemisphere and provide a measure of their rate of change over the last 20 years. Their findings will help us better understand -- and perhaps predict -- the impact of climate change north of the equator. |
| Towards greener smart cities with machine learning-based 'sleep schedules' Posted: 31 Jan 2022 10:19 AM PST While cellular networks are the foundation of smart cities, they consume a lot of energy, enhancing global warming. Putting base stations (BSs) with low traffic to sleep saves energy but also reduces traffic prediction accuracy. In a new study, researchers address this trade-off using machine learning technique to switch off BSs based on their contribution to prediction accuracy. The new scheme reduces power consumption and demonstrates a prediction accuracy superior to benchmark schemes. |
| Are cities the key to the electric revolution? Posted: 31 Jan 2022 09:21 AM PST A new article argues that cities need to use local policies and incentives to encourage the wider adoption of electric vehicles. The authors outline a number of steps cities can take to support the uptake of electric vehicles, such as leading by example and using fiscal mechanisms. The team also discuss factors that influence the electric revolution, including situational factors, contextual factors, and barriers and enablers. |
| Pioneering research forecasts climate change set to send costs of flooding soaring Posted: 31 Jan 2022 09:21 AM PST Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050 -- and disadvantaged communities will bear the biggest brunt, according to new research. |
| Wider-reaching solutions urgently needed to reach realistic 'net zero,' warn researchers Posted: 31 Jan 2022 08:05 AM PST There should be greater investment in using a wider group of experts to make decisions about how the landscape is managed if the UK is to reach climate targets such as net zero, a new report warns. |
| Some Finnish forest owners do not believe in biodiversity loss – for others it is a crisis Posted: 31 Jan 2022 06:50 AM PST We should start talking about biodiversity loss denial, just like we discussed climate change denial in the recent past, researchers say. |
| Study explores how temperate rainforests can aid the fight against climate change Posted: 31 Jan 2022 05:38 AM PST Research has shown that the level of growth needed to produce the amount of trees required by UK targets is unlikely to be achieved through natural means alone. |
| Scientists identify geological 'Goldilocks zone' for the formation of metal ore deposits Posted: 31 Jan 2022 05:38 AM PST Scientists have identified a mechanism through which important metals, crucial to the manufacturing of renewable energy technologies, are passed from the Earth's mantle to the crust. |
| Thawing permafrost can accelerate global warming Posted: 28 Jan 2022 07:07 AM PST Thawing permafrost in the Arctic could be emitting greenhouse gases from previously unaccounted-for carbon stocks, fuelling global warming. In the Siberian Arctic, the research team determined the origin of carbon dioxide released from permafrost that is thousands of years old. |
