NASA Awards Engineering Services and Science Capability Contract

NASA has selected Jacobs Technology of Tullahoma, Tennessee, to provide a broad spectrum of engineering and scientific support services at Marshall Space Flight Center in Huntsville, Alabama and the Michoud Assembly Facility in New Orleans.

'Nano-hashtags' could provide definite proof of Majorana particles

An advanced quantum chip will be able to provide definitive proof of the mysterious Majorana particles and a crucial step towards their use as a building block for future quantum computers, say researchers.

Major leap towards data storage at the molecular level

From smartphones to supercomputers, the growing need for smaller and more energy efficient devices has made higher density data storage one of the most important technological quests.

The breaking point: What happens around the edge of a crack?

What, exactly, happens right around the edge of the crack, in the area in which those large stresses are concentrated? A new study explains that the processes that take place in this region are universal -- they occur in the same way in different materials and under different conditions.

A more complete picture of the nano world

Aerosol particles are among the many materials whose chemical and mechanical properties cannot be fully measured until scientists develop a better method of studying materials at the microscale as well as the much smaller nanoscale (1 nm is one-billionth of a meter). Scientists have now developed such a method and utilized it to perform noninvasive chemical imaging of a variety of materials, as well as mechanical mapping with a spatial resolution of 10 nanometers.

What the world's tiniest 'monster truck' reveals

The world's shortest race by distance -- a fraction of the width of a human hair -- was a huge success for scientists working at the nanoscale. It spurred interest in molecular machines and led to a surprising new discovery, reports the team that entered a nano-sized 'monster truck.'

Researchers create magnetic RAM

MIPT researchers teamed up with collaborators for a successful demonstration of magnetoelectric random access memory (MELRAM). A transition to magnetoelectric memory could enable substantial energy savings, as well as the instantaneous startup of devices. Their paper was published in Applied Physics Letters.

NASA Astronauts Available for Interviews Before Space Station Mission

NASA astronauts Mark Vande Hei and Joe Acaba, who are making final preparations for a Sept. 12 launch to the International Space Station, will be available for live satellite interviews at 7 and 9 a.m. EDT, respectively, on Friday, Sept. 1.

It goes to 11: Florida lab sets new magnet strength record

Florida's National High Magnetic Field Laboratory is reclaiming its status as home to the world strongest magnet.

Getting hold of quantum dot biosensors

Harnessing the nano-tractor-beam like abilities of optical tweezers, researchers have developed an all-silicon nanoantenna to trap individual quantum dots suspended in a microfluidic chamber.
