Mildred Dresselhaus, a renowned physicist and celebrated Massachusetts Institute of Technology professor who earned the title “Queen of Carbon” for deepening the world’s understanding of the atomic properties of carbon and the electronic properties of materials, died on 20 February following a brief illness. She was 86.

The device also improves on previous "wearable" monitors with higher memory performance, courtesy of gold nanoparticles.

Only about 40 percent of used electronics are currently collected for recycling, and much of that is "down-cycled" into materials of lesser quality, but the computer company aims to change that.

An ultra-thin electronic device attaches to the skin like a temporary tattoo and measures heart rate and other vital signs without the bulky electrodes used in current hospital monitoring, reports a new study in the 11 August issue of the journal Science.

The device could also potentially be used as an electronic bandage to speed up healing in wounds, burns, and other skin conditions, and it could even provide touch sense to prosthetic devices such as artificial legs or arms.
