Electric fields in dust storms have been discovered lifting 10 times more dust into the air than winds alone, according to new experiments conducted in the Sahara Desert. The discovery has big implications for global climate studies, as well as for understanding dust storms on Mars.

Weather along the eastern coasts of South Africa, Asia, Australasia and South America will get significantly warmer and stormier on average over the next 100 years, a new study finds. The culprit? Climate changes that are causing ocean currents next to these coastal regions, called western boundary currents, to become stronger and extend further toward the poles, according to the new study.

Even if countries adhere to the Paris climate agreement hammered out last fall, capping global warming at 2 degrees Celsius (4 degrees Fahrenheit) would likely require net zero greenhouse gas emissions by 2085 and substantial negative emissions over the long term, according to an in-depth analysis by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.

There is some debate on what makes a river great. Is it its length? Its width? Ajit always thought it was more a matter of water volume, but after years of observing river plumes, he now opts for permanence. A river is great when its discharge has a detectable impact on the ocean; when its plume remains unmixed or fairly stable for a considerable period of time, without losing its idiosyncrasy.

After more than a decade of discussion and argument, the international open-science effort is looking for a roadmap to that single destination where it can consolidate its gains and allow science to reboot itself as entirely open. Several groups are calling for an integrative scholarly commons, where open-science objects—from ideas to published results—can be grown, shared, curated, and mined for new knowledge.
There are those who argue that predictability is the greatest gift of progress, the biggest merit of civilization. Our ability to explain nature through science makes the world and the universe predictable and understandable. That enables us to have a more informed and productive relationship with our natural environment and its resources.

Andreas Novotny thought he would find Hemiaulus here. He has not. “It is what it is, which is fine,” he says. “What we need to do is figure out why.” Andreas is a PhD. student and his research focuses in the symbiotic relationship between a kind of plankton, a Diatom called Rhizosolenia, and a Nitrogen-fixing Cyanobacteria, called Richelia.
An updated thermal model for Pluto suggests that liquid water beneath the dwarf planet’s ice shell may not be frozen yet.

A vast ocean of water beneath the icy crust of Saturn’s moon Enceladus may be more accessible than previously thought, according to new research. A new study has revealed that near the moon’s poles, the ice covering Enceladus could be just two kilometers (one mile) thick—the thinnest known ice shell of any ocean-covered moon. The discovery not only changes scientists’ understanding of Enceladus’ structure, but also makes the moon a more appealing target for future exploration, according to the study’s authors.

Natural oil and gas seeps exist on the ocean floor all over the world. Although humans have known about and exploited these natural resources for thousands of years, scientists know little about how oil and gas droplets disperse in deep water and how they affect underwater ecosystems.
