Cloudy with a Chance of...Solar Flares?

29.09.2014

Earl Scime, Oleg D. Jefimenko Professor of Physics and interim vice president of research at West Virginia University, has been awarded a grant from the National Science Foundation to better understand the effects of space weather.

Scime is using his $590,000 grant, to study double layers, structures composed of strong electric fields, found within plasma, capable of accelerating particles to high speeds. He is looking specifically at how these structures form, and what keeps them around in space.

It’s a small part of a bigger picture. Scime hopes to be able to model what is happening in space, in his lab, to be able to determine what exactly happens during powerful space storms.

On Sept. 11, a strong solar flare launched off of the sun, launching a massive burst of electrified gas into space. This is known as a coronal mass ejection. This burst and others like it continue to threaten technology on Earth and have been an area of interest for years at NASA.

The results of his studies could be used in sophisticated models of the space environment that would allow researchers to be able to predict whether or not a solar event will lead to harmful space weather. With advance warning, critical power, telecommunication, and other systems on Earth could be protected during a space weather storm.

“When we have large space weather events you can have power distribution systems fail, oil pipelines fail, spacecraft get knocked out permanently. Your standard communications satellite costs a couple-hundred million to a half a billion dollars. When those fail it can shut down long distance telephone communication for an entire country,” Scime said.

Scime specializes in space-relevant plasma physics and has recently also received $720,000 of funding from NASA for a project to build a micro-sized space instrument that will go into space and measure speed and density of particles in space, a whole new area of research at WVU.

“We hope to have our first prototypes ready by the end of next summer for testing. These are going to be space instruments the size of a sugar cube, but with the capabilities of instruments that, up to now, have been much larger,” Scime said.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
