$An artist’s embellishment of an image of the “gain medium” used to produce terahertz frequency combs. The different colors indicate that different wavelengths of oscillating terahertz radiation travel different distances through the medium, which has a different refractive index for each of them.$

Speedy terahertz-based system could detect explosives

Spectroscopic system with chip-scale lasers cuts detection time from minutes to microseconds.

A sample of a core-shell nanoparticle made by the researchers is shown in images made using scanning transmission electron microscope (STEM) and energy-dispersive x-ray spectroscopy (EDX). Color images show where the different elements are located in the particle, with the precious metals platinum (Pt) and ruthenium (Ru) concentrated in the shell, and the other constituents, tungsten (W), and tita...

New nanoparticle catalysts could reduce need for precious metals

Process from MIT provides improved reactivity with much less platinum.

“I think just by talking to each other and helping people, not only do you potentially inspire someone, or help them make the right choice, but also you learn a lot yourself,” Donald Little says.

Helping others in daily doses

Senior Donald Little uses computer science to improve people’s everyday lives.

These images show the crystal configurations, or phases, within samples of metal alloys: a single-phase stable alloy (left) and a dual-phase alloy (right), which is metastable (has more than one stable configuration). The dual-phase material turns out to have better strength and ductility than the singe-phase material, the researchers found.

New metal alloys overcome strength-ductility tradeoff

Promising new approach overturns widespead metallurgical assumption.

“[W]hen you send location data as a secondary piece of information, it is extremely simple for people with very little technical knowledge to find out where you work or live,” Ilaria Liccardi says.

We know where you live

From location data alone, even low-tech snoopers can identify Twitter users’ homes, workplaces.

A new cell-sorting device consists of a microfluidic channel that vibrates at a very high frequency. As cells flow through the channel, they are pushed to a certain position depending on how they interact with the acoustic forces generated by the vibration. Pictured is an example of the device.

New approach to sorting cells

Microfluidic device distinguishes cells based on how they respond to acoustic vibrations.
