This research may lead to much faster computers that take advantage of the natural magnetism of electrons, as opposed to just their charge. Spintronics is a new area of condensed matter physics that attempts to use the intrinsic magnetic moment of electrons, called "spins,"...

The ability to freeze cells and even whole organs without damaging them, known as cryoprotection, is of considerable interest to medical practitioners, and scientists have experimented with chemicals called polyampholytes as cryoprotectants. In an article recently published in

New, wearable cortisol sensor can help warn us of incoming burnout or depression Though to be fair, aren’t we all at risk of that currently? It’s no secret that life can get rough. Those who have to contend with that for too long can start feeling overwhelmed — burned out by the stress. Now, a team of researchers proposes a new approach through which we can quantify how much stress someone is under, and for how long. They hope that the new wearable device can help prevent burnout, and let us know when someone is most in need of support or a good old fashioned break from the stress.

From the inside it's not hard to tell if you're stressed. You might feel agitated, notice your shoulders or jaw tense up, get headaches, or even lie awake at night.

Nano-vault architecture alleviates stress in Si-based anodes for Li-ion batteries New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. The unique properties of the structure, which was built using nanoparticle technology, are revealed and explained in an open-access paper in the Nature journal Communications Materials. Nanomaterials undergoing cyclic swelling-deswelling benefit from inner void spaces that help accommodate significant volumetric changes. S...
