Genes, ozone, and autism
Fri, 23 Jun 2017 15:55:11 EDT
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism.
Hot summer frequents Europe-west Asia and northeast Asia after the mid-1990s
Wed, 21 Jun 2017 10:30:45 EDT
A recent research identifies a nonuniform warming pattern in summer after the mid-1990s over the Eurasian continent, with a predominant amplified warming over Europe-West Asia and Northeast Asia but much weaker warming over Central Asia. The study also implies that there will still be a strong warming over Europe-West Asia and Northeast Asia in the coming decade.
Chemistry of sea spray particles linked for first time to formation process
Mon, 19 Jun 2017 15:15:28 EDT
For the first time, researchers have identified what drives the observed differences in the chemical make-up of sea spray particles ejected from the ocean by breaking waves.
Deadly heatwaves expected to continue to rise
Mon, 19 Jun 2017 12:05:07 EDT
Seventy-four percent of the world's population will be exposed to deadly heatwaves by 2100 if carbon gas emissions continue to rise at current rates, according to a new study. Even if emissions are aggressively reduced, the percent of the world's human population affected is expected to reach 48 percent.
California named state with the worst air quality (again)
Mon, 19 Jun 2017 09:27:49 EDT
High ozone levels and a quickly growing population are making it tough to implement regulations to reduce pollution, says a professor.
Six key impact areas of shale oil and gas development in Texas
Mon, 19 Jun 2017 09:22:11 EDT
A comprehensive review of the impacts of oil and gas development in Texas by a cross-disciplinary task force of top researchers finds a wide range of both benefits and consequences for the state's environment and communities.
Dryland cropping systems research addresses future drought and hunger issues
Thu, 15 Jun 2017 21:37:28 EDT
The projected world population by 2056 is 10 billion. If researchers succeed in improving the yield potential of 40 percent of global land area under arid and semi-arid conditions, it will lead to a significant contribution to future food security.
Global diet and farming methods 'must change for environment's sake'
Thu, 15 Jun 2017 21:32:58 EDT
Reducing meat consumption and using more efficient farming methods globally are essential to stave off irreversible damage to the environmental, a new study says. The research also found that future increases in agricultural sustainability are likely to be driven by dietary shifts and increases in efficiency, rather than changes between food production systems.
Water management interventions push scarcity downstream
Thu, 15 Jun 2017 08:50:15 EDT
Human interventions to harness water resources, such as reservoirs, dams, and irrigation measures, have increased water availability for much of the global population, but at the same time, swept water scarcity problems downstream.
Widespread snowmelt in West Antarctica during unusually warm summer
Thu, 15 Jun 2017 08:46:01 EDT
An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Nino blew over the continent.
Wildfires pollute much more than previously thought
Wed, 14 Jun 2017 11:28:19 EDT
Wildfires are major polluters. Their plumes are three times as dense with aerosol-forming fine particles as previously believed. For the first time, researchers have flown an orchestra of modern instruments through brutishly turbulent wildfire plumes to measure their emissions in real time. They have also exposed other never before measured toxins.
Energy-efficient cleaning robot

State-of-the-art solar cells are efficient -- but are even more so when they are kept clean. A cleaning robot enables solar panels to deliver at full capacity.
Solar material for producing clean hydrogen fuel
Wed, 14 Jun 2017 09:26:07 EDT
A new material has been created based on gold and black phosphorus to produce clean hydrogen fuel using the full spectrum of sunlight.
Volcanic 'plumerang' could impact human health
Mon, 12 Jun 2017 09:44:02 EDT
A new study has found a previously undetected potential health risk from the high concentration of small particles found in a boomerang-like return of a volcanic plume.
Lost ecosystem found buried in mud of southern California coastal waters
Fri, 09 Jun 2017 09:12:20 EDT
Paleontologists investigating the sea bed off California have discovered a lost ecosystem that for thousands of years had nurtured communities of scallops and shelled marine organisms called brachiopods. They had died off by the early 20th century, replaced by the mud-dwellling burrowing clams that inhabit this seabed today.
