Stopping Sound with Foam. Experiments with this foam (shown under a microscope) showed that at certain frequencies, the bubbles and the surrounding liquid vibrate out of synch in response to an ultrasound wave, completely suppressing the transmission of sound. (Via APS physics).
This simulation of a one-nanometer wide Indium Nitride wire shows the distribution of an electron around a positively charged ‘hole.’ Strong quantum confinement in these small nanostructures enables efficient light emission at visible wavelengths.

An awesome project. You can perfectly spend the day (or the week) navigating through these sites.
The Human Connectome Project aims to provide an unparalleled compilation of neural data, an interface to graphically navigate this data and the opportunity to achieve never before realized conclusions about the living human brain.
The top of this image shows how early in the heating, magnetic fields, drawn as black lines, prevent heat from flowing easily between the two yellow laser spots. Later in the heating, as depicted on the bottom half, the moving magnetic fields continually connect and provide a channel for heat to flow between the two laser spots. This newly discovered magnetic behavior could advance nuclear fusion.

This incredibly detailed image of an ant obtained at the ESRF’s ID19 beamline is based on a technique called X-ray grating interferometry, which provides high-sensitivity differential phase and dark-field (small angle X-ray scattering) signals. It therefore bears tremendous potential for imaging tiny density differences and structures at the nanoscale that produce low absorption contrast.
20 years of battery life! The NanoTritium betavoltaic power source from City Labs is a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years.
