Near two million acres on fire in the United States

The West Coast of the United States is shrouded in smoke from the 110 large fires (this does not include smaller fires within each complex of fires) that have erupted across the region during this fire season.

Supercomputing simulations and machine learning help improve power plants

Researchers are exploring how supercritical carbon dioxide could serve as a cleaner, safer, and more flexible working fluid in power plants than supercritical water by using supercomputing resources and machine learning.

Nice sunny days can grow into heat waves -- and wildfires: summer weather is stalling

Stalling summer weather as we are experiencing right now in the Northern hemisphere can turn into 'extreme extremes' from heat to drought, from rain to flood.

The environmental cost of contact lenses

Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.

Acid coastal seas off US putting common fish species at risk

Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod.

Making aquafeed more sustainable: Scientists develop feeds using a marine microalga co-product

Scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia.

Ants, acorns and climate change

The relatively swift adaptability of tiny, acorn-dwelling ants to warmer environments could help scientists predict how other species might evolve in the crucible of global climate change, according to biologists.

Particulate pollution's impact varies greatly depending on where it originated

Aerosols are tiny particles that are spewed into the atmosphere by human activities, including burning coal and wood. They have negative effects on air quality -- damaging human health and agricultural productivity. New research demonstrates that the impact these fine particles have on the climate varies greatly depending on where they were released.

Microfossils, possibly world's oldest, had biological characteristics

Scientists have confirmed that the 3.4-billion-year-old Strelley Pool microfossils had chemical characteristics similar to modern bacteria. This all but confirms their biological origin and ranks them amongs the world's oldest microfossils.

Human wastewater valuable to global agriculture, economics

It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries, says a new study.

Previously grainy wheat genome comes into focus

An international consortium has completed the sequence of wheat's colossal genome.

Highly effective natural plant-based food preservative discovered

Scientists have discovered a plant-based food preservative that is more effective than artificial preservatives.

First biomarker evidence of DDT-autism link

A study of more than 1 million pregnancies in Finland reports that elevated levels of a metabolite of the banned insecticide DDT in the blood of pregnant women are linked to increased risk for autism in the offspring. The study is the first to connect an insecticide with risk for autism using maternal biomarkers of exposure.

Study of material surrounding distant stars shows Earth's ingredients 'pretty normal'

The Earth's building blocks seem to be built from 'pretty normal' ingredients, according to researchers working with the world's most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere.

Particles pull last drops of oil from well water

Engineers develop magnetic nanoparticles that separate the last droplets of oil from produced water at wells.

Frequent fires make droughts harder for young trees, even in wet eastern forests

Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study provides answers.

Water use for fracking has risen by up to 770 percent since 2011

The amount of water used per well for fracking surged by up to 770 percent between 2011 and 2016 in all major US shale gas- and oil-producing regions, a new study finds. The volume of flowback and produced water that new wells generated during their first year of operation also increased by up to 1,440 percent. If this rapid intensification continues, fracking's water footprint could grow by up to 50-fold by the year 2030.

When viruses infect phytoplankton, it can change the clouds

Microscopic plant-like organisms called phytoplankton support the diversity of life in the ocean. Scientists now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement.

Next 5 years predicted to be abnormally hot

This summer's worldwide heatwave makes 2018 a particularly hot year. As will be the next few years, according to a new study. Using a new method, the study shows that at the global level, 2018-2022 may be an even hotter period than expected based on current global warming.

Study of greater Yellowstone pronghorn finds highway crossing structures a conservation success

A recently published study has confirmed that efforts to protect migrating pronghorn by installing wildlife crossing structures over highways have succeeded, in terms of the increased success rate of pronghorn crossings over time.
