Nature-based solutions can help protect us from climate-related natural hazards Posted: 17 Oct 2019 08:17 AM PDT Solutions found in nature should be our first line of defense against the increasing number of climate change-related natural disasters, say experts. |
What happens under the Yellowstone Volcano? Posted: 17 Oct 2019 08:17 AM PDT A recent study helps to better explain the processes in the Earth's interior beneath the Yellowstone supervolcano. |
First widespread chytrid fungus infections in frogs of Peruvian Amazon rain forests Posted: 17 Oct 2019 08:17 AM PDT Biologists have documented, for the first time, the widespread presence of the notorious chytrid fungus in 80 species of frogs from lowland rain forest sites in the Peruvian Amazon. |
Deep water sites off the US northeast coast are suitable for offshore blue mussel farms Posted: 17 Oct 2019 07:12 AM PDT Offshore mussel farm sites need to have the right temperature, food availability, and the right currents. According to a study, several suitable locations can be found off the Northeastern US. |
Photosynthesis Olympics: Can the best wheat varieties be even better? Posted: 17 Oct 2019 07:12 AM PDT Scientists have put elite wheat varieties through a sort of 'Photosynthesis Olympics' to find which varieties have the best performing photosynthesis. This could ultimately help grain growers to get more yield for less inputs in the farm. |
Breaking water molecules apart to generate clean fuel: Investigating a promising material Posted: 17 Oct 2019 07:12 AM PDT 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. |
Old friends and new enemies: How evolutionary history can predict insect invader impacts Posted: 17 Oct 2019 04:56 AM PDT Scientists have developed a model that could help foresters predict which nonnative insect invasions will be most problematic. This could help managers decide where to allocate resources to avoid widespread tree death. |
Information theory as a forensics tool for investigating climate mysteries Posted: 17 Oct 2019 04:55 AM PDT During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events. |
Ants inhibit at least 14 different plant diseases Posted: 17 Oct 2019 04:55 AM PDT New research shows that ants inhibit at least 14 different plant diseases. The small insects secrete antibiotics from glands in the body. On their legs and body, they also host colonies of bacteria that secrete antibiotics. It is probably these substances that inhibit a number of different diseases and researchers now hope to find biological pesticides that may conquer resistant plant diseases. |
Scientists find early humans moved through Mediterranean earlier than believed Posted: 16 Oct 2019 12:36 PM PDT Scientists have unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed. |
Tiny particles lead to brighter clouds in the tropics Posted: 16 Oct 2019 10:12 AM PDT When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a new study. Clouds alter Earth's radiative balance, and ultimately climate, depending on how bright they are. The new paper describes a process that may occur over 40% of the Earth's surface. |
3-D printed coral could help endangered reefs Posted: 16 Oct 2019 09:46 AM PDT Threats to coral reefs are everywhere -- rising water temperatures, ocean acidification, coral bleaching, fishing and other human activities. But new research shows that 3-D printed coral can provide a structural starter kit for reef organisms and can become part of the landscape as fish and coral build their homes around the artificial coral. |
The moon determines when migratory birds head south Posted: 16 Oct 2019 09:46 AM PDT A new study shows that the presence or absence of moonlight has a considerable bearing on when migratory birds take flight in the autumn. |
Climate change increases risk of mercury contamination Posted: 16 Oct 2019 09:45 AM PDT As global temperatures continue to rise, the thawing of permafrost is accelerated and mercury trapped in the frozen ground is now being released. The mercury is transforming into more mobile and potentially toxic forms that can lead to environmental and health concerns for wildlife, the fishing industry and people in the Arctic and beyond. |
Galapagos study highlights importance of biodiversity in the face of climate change Posted: 16 Oct 2019 09:45 AM PDT Study of wave turbulence suggests that highly mobile species and more diverse ecological communities may be more resilient to the effects of changing environmental conditions. |
Computer models show clear advantages in new types of wind turbines Posted: 16 Oct 2019 09:45 AM PDT Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction. |
Distribution of highly radioactive microparticles in Fukushima revealed Posted: 16 Oct 2019 08:11 AM PDT New method allows scientists to create a quantitative map of radioactive cesium-rich microparticle distribution in soils collected around the damaged Fukushima Daiichi Nuclear Power Plant Nuclear Power Plant (FDNPP). This could help inform clean-up efforts in Fuksuhima region. |
Are we underestimating the benefits of investing in renewable energy? Posted: 16 Oct 2019 06:49 AM PDT 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 Posted: 16 Oct 2019 04:47 AM PDT 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%. |
Climate change concerns have largely ignored role of access to effective contraception Posted: 15 Oct 2019 04:29 PM PDT Climate change concerns have largely ignored the importance of universal access to effective contraception, despite the impact of population growth on greenhouse gas emissions, argue experts. |
Airborne chemicals instantly identified using new technology Posted: 15 Oct 2019 02:15 PM PDT 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 Posted: 15 Oct 2019 02:15 PM PDT 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. |
Increased risk of tularemia as the climate changes Posted: 15 Oct 2019 01:47 PM PDT Researchers have developed a method for statistically predicting impacts of climate change on outbreaks of tularemia in humans. New results show that tularemia may become increasingly common in the future in high-latitude regions. |
Artificial intelligence and farmer knowledge boost smallholder maize yields Posted: 15 Oct 2019 01:46 PM PDT Farmers in Colombia's maize-growing region of Córdoba had seen it all: too much rain one year, a searing drought the next. Yields were down and their livelihoods hung in the balance. To better deal with climate stress, farmers in Colombia's maize-growing region of Córdoba needed information services that would help them decide what varieties to plant, when they should sow and how they should manage their crops. |
