How to Help Californians Affected by the North Bay Wildfires
October 10, 2017 04:21 PM - S.E. SMITH

Fast-moving wildfires are devastating parts of Northern California, including Sonoma and Napa Counties, just north of the Bay Area. Victims — and their animals — displaced by evacuation orders and property loss need your help.

Giant Bacteria Make Algae Easy to Stomach
October 10, 2017 12:06 PM - King Abdullah University of Science & Technology (KAUST)

Red Sea surgeonfish use metabolically diverse giant bacteria to digest different types of algae, according to new research. Not only do these findings explain the basis of surgeonfish diversity, but they may also provide a valuable genetic resource for biofuel research.

Conservationists' Eco-Footprints Suggest Education Alone Won't Change Behaviour

Conservationists work to save the planet, and few are as knowledgeable when it comes to the environmental pressures of the Anthropocene.

Clear Lakes Disguise Impaired Water Quality
October 10, 2017 11:52 AM - University of Minnesota

Looks can be deceiving.

Look at a hundred lakes in the agricultural heartland of the United States and you will likely see green lakes surrounded by green fields. The nitrogen and phosphorus in agricultural fertilizers that help crops grow also fuel the growth of algae and cyanobacteria that in excess can turn lakes the color of pea soup.

What Earth's climate system and topological insulators have in common

New research shows that equatorial waves — pulses of warm ocean water that play a role in regulating Earth’s climate — are driven by the same dynamics as the exotic materials known as topological insulators.

Heating Dirt Could Cause a Runaway Rise in Carbon Emissions

Tucked into the apple-growing hills of Western Massachusetts is the Harvard Forest, a 3,700-acre wooded preserve that hosts school kids on field trips, day-tripping hikers, and, for more than a quarter century, a highly unusual science experiment.

Microbes Dictate Regime Shifts Causing Anoxia in Lakes and Seas
October 6, 2017 11:46 AM - University of Amsterdam

Gradual environmental changes due to eutrophication and global warming can cause a rapid depletion of oxygen levels in lakes and coastal waters. A new study led by professors Jef Huisman and Gerard Muyzer of the University of Amsterdam (UvA) shows that microorganisms play a key role in these disastrous regime shifts. The researchers’ findings were published in the journal Nature Communications on 6 October.

Sunlight and the right microbes convert Arctic carbon into carbon dioxide
October 5, 2017 04:50 PM - Oregon State University

Nearly half of the organic carbon stored in soil around the world is contained in Arctic permafrost, which has experienced rapid melting, and that organic material could be converted to greenhouse gases that would exacerbate global warming.

Australia Experiences Surge in Deforestation
October 5, 2017 04:46 PM - Yale Environment 360

Nearly 1 million acres of trees were cut down in Queensland, Australia from 2015 to 2016, representing a 33 percent rise in deforestation, according to a new government land survey.
