A quantum dot energy harvester

A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. The engines would be microscopic in size, and have no moving parts. Each would only produce a tiny amount of power but by combining millions of the engines in a layered structure, enough of them could make a notable difference in the energy consumption of a computer.

Combining quantum information communication and storage

Researchers in Finland have successfully connected a superconducting quantum bit, or qubit, with a micrometer-sized drum head. Thus they transferred information from the qubit to the resonator and back again.

MSFC, USSRC to Hold 'Robots to Rocket City' Event Feb. 17

NASA's Marshall Space Flight Center in Huntsville, Ala., will cohost a "Robots to Rocket City" event Feb. 17.

NASA Targets March 1 Launch for Next SpaceX Station Resupply Mission; Media Accreditation Open

NASA and its international partners are targeting Friday, March 1, as the launch date for the next cargo resupply flight to the International Space Station by Space Exploration Technologies (SpaceX).

NASA'S Fermi Proves Supernova Remnants Produce Cosmic Rays

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe.

NASA Awards Final Space Launch System Advanced Booster Contract

NASA has selected Aerojet of Sacramento, Calif., for a $23.3 million contract to develop engineering demonstrations and risk reduction concepts for future advanced boosters for the agency's Space Launch System (SLS).

Team creates MRI for the nanoscale

Magnetic resonance imaging (MRI) reveals details of living tissues, diseased organs and tumors inside the body without x-rays or surgery. What if the same technology could peer down to the level of atoms? Doctors could make visual diagnoses of a person's molecules – examining damage on a strand of DNA, watching molecules misfold, or identifying a cancer cell by the proteins on its surface.

Semiconductor interfaces: Big opportunities for tiny insulators

A model that predicts real-world behaviors of insulator interfaces makes designing ‘nano-electronic’ materials significantly simpler.

Light-emitting bioprobe fits in a single cell

A new study is the first to demonstrate that sophisticated, engineered light resonators can be inserted inside cells without damaging the host. The researchers say it marks a new age in which tiny lasers and light-emitting diodes yield new avenues in the study and influence of living cells.

Team creates MRI for the nanoscale: Level comparable to an atomic force microscope

An international team of researchers has opened the door for MRI technology at the nanoscale. Using tiny defects in diamonds they sensed the magnetic resonance of molecules to peer down to the level of atoms.
