It Takes a Community of Soil Microbes to Protect Plants From Disease

*Berkeley Lab scientists decipher immune system for plants beneath our feet*

Those vegetables you had for dinner may have once been protected by an immune system akin to the one that helps you fight disease. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Netherland’s Wageningen University found that plants rely on a complex community of soil microbes to defend themselves against pathogens, much the way mammals harbor a raft of microbes to avoid infections.

The scientists deciphered, for the first time, the group of microbes that enables a patch of soil to suppress a plant-killing pathogen. Previous research on the phenomenon of disease-suppressive soil had identified one or two pathogen-fighting microbes at work. (more…)

Clouds, a Weapon Against Climate Change?

University of Georgia researchers define a missing link in how clouds are formed

Some clouds cool the earth. But how are these clouds formed? How does the chemistry of the ocean affect their formation? Is this process affected by climate change? Can humans affect cloud formation to increase the cooling effect of clouds, having positive implications for the health of the planet? (more…)

Why Some Planets Orbit the Wrong Way; Extrasolar Insights into Our Solar System

More than 500 extrasolar planets–planets that orbit stars other than the sun–have been discovered since 1995. But only in the last few years have astronomers observed that in some of these systems, the star is spinning one way and the planet is orbiting that star in the opposite direction.

“That’s really weird, and it’s even weirder because the planet is so close to the star,” said Frederic A. Rasio, a theoretical astrophysicist at Northwestern University. “How can one be spinning one way and the other orbiting exactly the other way? It’s crazy. It so obviously violates our most basic picture of planet and star formation.” (more…)

NASA’s Galileo Reveals Magma ‘Ocean’ Beneath Surface of Jupiter’s Moon

A new analysis of data from NASA’s Galileo spacecraft has revealed that beneath the surface of Jupiter’s volcanic moon Io is an “ocean” of molten or partially molten magma.

The finding, from a study published May 13 in the journal Science, is the first direct confirmation of such a magma layer on Io and explains why the moon is the most volcanic object known in the solar system. The research was conducted by scientists from UCLA, UC Santa Cruz and the University of Michigan–Ann Arbor. (more…)

Africa’s Sea Turtles Need Passports for Protection

Research by experts at the University of Exeter has led to calls to create an international marine park to protect endangered sea turtles.

Scientists from the university’s Centre for Ecology and Conservation, based at its Cornwall Campus, worked with an international team to carry out satellite tracking of olive ridley sea turtles off the coast of Central Africa for the study. (more…)
