'Green'-feed: Industrial microbes could feed cattle, pigs, chicken

Wed, 20 Jun 2018 09:48:25 EDT ~ Today, producing feed for pigs, cattle and chicken causes immense impacts for the climate and the environment. In the future, animal feed production is likely to be shifted from croplands to large-scale industrial facilities as it could bring both financial and environmental benefits. Replacing 2 percent feed with protein-rich microbes could decrease agricultural greenhouse gas emissions, global cropland area and nitrogen losses by over 5 percent. Find out more...

Light pollution a reason for insect decline

Tue, 19 Jun 2018 12:24:56 EDT ~ Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future.

Reduction in sulfur emissions from power plants in China

Mon, 18 Jun 2018 22:26:20 EDT ~ Air pollution has smothered China's cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now scholars show that one of China's key antipollution laws is indeed working -- but unevenly, with one particular set of polluters most readily adapting to it.

Overuse of agricultural chemicals on China's small farms harms health and environment

Mon, 18 Jun 2018 22:25:11 EDT ~ The size of farms in China is a key contributor to the overuse of agricultural chemicals, and as a result they may be too small to be environmentally sustainable, a new study has found. Find out more...

Meeting Paris climate targets will require a substantial reallocation of global investment

Mon, 18 Jun 2018 11:30:33 EDT ~ A new analysis by an international team of scientists shows that low carbon investments will need to markedly increase if the world is to achieve the Paris Agreement aim of keeping global warming well below 2C. Find out more...

Orange, tea tree and eucalyptus oils sweeten diesel fumes

Fri, 15 Jun 2018 18:55:31 EDT ~ Waste oil from orange, tea tree and eucalyptus essential oil production mixed with diesel provides a sweet-smelling biofuel blend with comparable performance to diesel-only fuel. Find out more...

New method makes weather forecasts right as rain

Fri, 15 Jun 2018 15:45:05 EDT ~ Meteorologists have known for some time that rainfall forecasts have flaws, as failure to take into account factors such as evaporation can affect their accuracy. Now, researchers have developed a system that improves the precision of forecasts by accounting for evaporation in rainfall estimates, particularly for locations 30 miles or more from the nearest National Weather Service radar.

Plants open their pores and scientists strike gold

Thu, 14 Jun 2018 09:52:26 EDT ~ Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers have identified and investigated the characteristics of gold nanoparticles in two plant species growing in their natural environments. Find out more...

Ammonia distribution in Earth's upper atmosphere

Wed, 13 Jun 2018 16:28:31 EDT ~ A new study helps clarify how ammonia is present in Earth's upper atmosphere. Using computer modeling, the researchers found ammonia molecules trapped in liquid cloud droplets are released during convection where these particles freeze and subsequently collide in the upper atmosphere.

MOF material offers selective, reversible and repeatable capture of toxic atmospheric gas

Mon, 11 Jun 2018 13:38:32 EDT ~ Scientists have developed a metal-organic framework material with a selective, fully reversible and repeatable capability to remove atmospheric nitrogen dioxide gas in ambient conditions. The discovery, confirmed by researchers using neutron scattering, could facilitate air filtration technologies that capture and convert targeted gases, including carbon dioxide and other greenhouse gases, for long-term sequestration to mitigate air pollution and global warming.
