What's the buzz

According to an analysis, potentially hazardous electrical fields exist in the moon’s polar regions. The phenomenon may be responsible for levitating dust from the moon’s surface.

The finding is applicable to other small, air-less bodies, like asteroids. Moon explorers should be warned that travelling through the pits might result in nasty electrical shocks.
That’s because crater walls effectively block plasma streaming from the sun, leaving little electrically charged matter to cancel out static buildup from a rover on the move, an astronaut walking, or any other activity that generates friction.
“The last thing you want to do is drive a rover wheel and have it charging up and then have an astronaut walking by and have it discharge,” said Bill Farrell, a plasma physicist at NASA’s Goddard Space Flight Centre in Greenbelt.

Diamonds travel at 60 km per hour inside Earth
Diamond infused magma travel to the surface of the earth from deep within the planet at a blistering 60 kilometres per hour.
Rising magma in Earth’s mantle is thought to ascend at just a few centimetres per year.
It was known that kimberlite, which often contains diamonds, can rise more quickly near the surface, but its speed at great depths was unclear. And now, Masayuki Nishi and colleagues at Kyushu University in Fukuoka, Japan, have used the mineral garnet as a speedometer. Garnet inclusions that form inside diamond are stable at depths of between 400 and 700 km, but partially degrade at lower pressures and temperatures.
The researchers synthesised garnet in heated, pressurised containers and measured how fast it degraded as the temperature and pressure were lowered, simulating ascent through Earth’s mantle. And the rate of decay suggested that for a garnet-infused diamond to reach the surface it must take between hours and days to travel from a depth of 400 km.

A rapid ascent mechanism may exist at greater depths than ever thought, said Nishi.
Organic solids in soil enable bacterial breathing
Organic solids in soil may speed up bacterial breathing, a new study has found.
Led by University of Wisconsin-Madison geoscientist Eric Roden, the new research shows that iron oxide-breathing bacteria can also ‘mineral-breathe’ with insoluble organic substances, formed when plants and other organic materials biodegrade in soils and sediments. During respiration, the bacteria release electrons that interact with nearby substances, a process called reduction.
Reduction of large organic molecules — called humics and familiar to gardeners as part of planting soil — represents a new pathway for electrical charges to move around in the environment, with implications for understanding soil chemistry and environmental contamination.
