Michigan Technological University scientists led by professor of physics Yoke Khin Yap have created a quantum tunneling device that acts like like an FET transistor and works at room temperature — without using semiconducting materials.

The trick was to use boron nitride nanotubes (BNNTs) with quantum dots made from gold.

When sufficient voltage is applied to the device, it switches from insulator to a conducting… read more

Gladstone Institutes and Salk Institute researchers have assembled brain-wide maps of neurons that connect with the basal ganglia, a region of the brain involved in movement and decision-making.

Developing a better understanding of this region is important as it could inform research into disorders causing basal ganglia dysfunction, including Parkinson’s disease and Huntington’s disease.

An ultrasensitive molybdenum-based image sensor

June 28, 2013

molybdenite_sensor

An EPFL team has built a prototype image sensor based on the semiconducting properties of molybdenite (molybdenum disulfide, MoS2). It could one day result in cameras that are five times more light-sensitive than current technology.

This level of sensitivity would open up the huge area of low-light or night photography, without resorting to “noise”-generating amplification techniques or high-ISO settings, slowing down the shutter speed, using… read more

Neurala to turn robots into ‘adaptive, learning beings’

June 27, 2013

neurala_logo

Cambridge startup Neurala expects that its software for giving intelligence and autonomy to robots will part of commercial products by the end of the year, CEO and co-founder Max Versace said in an interview with Boston Business Journal.

The software aims to allow humans to control robots by telling them what to do, instead of operating them using remote control or programming for a specific… read more

Extreme-ultraviolet microscope goes online at Berkeley Lab

Will help drive chip making to new levels of miniaturization and complexity
June 27, 2013

Created by the Center for X-Ray Optics at Berkeley Lab, SHARP gives researchers from the world's leading semiconductor companies a window into the future of computer-chip fabrication.

The world’s most advanced extreme-ultraviolet microscope is about to go online at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), and the queue of semiconductor companies waiting to use it already stretches out the door.

The much-anticipated SHARP microscope (SEMATECH High-NA Actinic Recticle review Project) was conceived and built by scientists at Berkeley Lab’s Center for X-ray Optics (CXRO) and will provideread more

The ‘Internet of cars’ is approaching a crossroads

Wireless vehicle networks could make driving safer, more efficient, and less polluting, but the cost of deployment will be significant, MIT Technology Review reports.

This week, officials from the U.S. Department of Transportation in Washington, DC, will see the technology in action, in a demonstration organized by experts from the University of Michigan’s Transportation Research Institute and various communications equipment and car manufacturers.… read more

Siri’s creators demonstrate predictive assistant for office workers

June 27, 2013

sri_bright

SRI, is developing Bright, an intelligent assistant that could someday know what information you need before you even ask, MIT Technology Review reports.

Initially, Bright is meant to cut down on the cognitive overload faced by workers in high-stress, data-intensive jobs like emergency response and network security.

But it could eventually trickle down to laptops and smartphones as a “cognitive desktop” and… read more

Solar-power materials head in a new direction: thinner

Atom-thick photovoltaic sheets could pack hundreds of times more power per weight than conventional solar cells
June 27, 2013

The MIT team found that an effective solar cell could be made from a stack of two one-molecule-thick materials: Graphene (a one-atom-thick sheet of carbon atoms, shown at bottom in blue) and molybdenum disulfide (above, with molybdenum atoms shown in red and sulfur in yellow). The two sheets together are thousands of times thinner than conventional silicon solar cells.<br />

MIT researchers are opening a new avenue for improving solar cells, aiming to produce the thinnest and most lightweight solar panels possible.

Such panels, which have the potential to surpass any substance other than reactor-grade uranium in terms of energy produced per pound of material, could be made from stacked sheets of one-molecule-thick materials such as graphene or molybdenum disulfide.
