Graphene Helps Study Epilepsy and Other Brain Disorders

October 21, 2014 | News | Comments

Researchers have used graphene to fabricate a new type of microelectrode that solves a major problem for investigators looking to understand the intricate circuitry of the brain. Because of graphene's nonmagnetic and anti-corrosive properties, these probes can be a very promising technology to increase the longevity of neural implants.

Resolving a Major Biological Controversy

October 21, 2014 12:00 am | by Janet Lathrop, UMass Amherst | News | Comments

The claim by microbiologist Derek Lovley and colleagues at the University of Massachusetts Amherst that the microbe Geobacter produces tiny electrical wires, called microbial nanowires, has been mired in controversy for a decade, but the researchers say a new collaborative study provides stronger evidence than ever to support their claims.

Building a Reversible Tractor Beam

October 21, 2014 12:00 am | News | Comments

Laser physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam that is bright around the edges and dark in its center. It is the first long-distance optical tractor beam and moved particles one fifth of a millimeter in diameter a distance of up to 20 centimeters, around 100 times further than previous experiments.

NASA Mars Rovers Duck and Cover from Comet

October 20, 2014 10:24 am | News | Comments

All three NASA orbiters around Mars have confirmed their healthy status after each took shelter behind Mars during a period of risk from dust released by a passing comet. The comet sped past Mars on Oct. 19 much closer than any other known comet flyby of a planet. The opportunity to study this rare near-miss of a planet by a comet comes during the MAVEN project's commissioning phase.

Medical Device Battles Bladder Disease

October 20, 2014 10:12 am | by Rob Matheson, MIT News Office | News | Comments

The millions of people worldwide who suffer from the painful bladder disease known as interstitial cystitis may soon have a better, long-term treatment option, thanks to a controlled-release, implantable device invented by a team from MIT. The pretzel-shaped silicone tube can be inserted into the bladder, and slowly releases lidocaine over two weeks.

Simplifying Superconducting Circuits

October 17, 2014 11:48 am | by Larry Hardesty, MIT News Office | News | Comments

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet’s most popular sites. But those chips are big and hard to make. A new circuit design could make simple superconducting devices much cheaper to manufacture.

NASA Spacecraft Explores Climate Change on Mars

October 17, 2014 10:52 am | by Robert Sanders, Media Relations, UC Berkeley | News | Comments

NASA’s MAVEN spacecraft settled into its planned orbit around Mars on Sept. 21 and is already sending back data about the upper atmosphere. This data can help help space scientists understand why some planets, like Earth and Venus, still have thick atmospheres, while others, like Mars and Mercury, do not.

Fabricating Graphene Nanoribbons Will Revolutionize Electronics

October 17, 2014 10:40 am | by Shaun Mason, UCLA | News | Comments

Scientists have discovered a new self-assembly method for producing defect-free graphene nanoribbons with periodic zigzag-edge regions. In this “bottom-up” technique, researchers use a copper substrate’s unique properties to change the way the precursor molecules react to one another as they assemble into graphene nanoribbons. This allows the scientists to control the nanoribbons’ length, edge configuration, and location on the substrate.
