Tiny, wireless antennas use light to monitor cellular communication

Researchers developed a biosensing technique that eliminates the need for wires. Instead, tiny, wireless antennas use light to detect minute electrical signals in the solution around them.

Generate electricity by attaching device to your clothes

A research team has developed a highly efficient wearable energy harvester that can power electronic devices using only body movements.

Engineers grow 'high-rise' 3D chips

Researchers can now fabricate a 3D chip with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon substrates between the layers, leading to better and faster computation, for applications like more efficient AI hardware.

Physics: Current generated by the quantum Hall effect has additional magnetic properties

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. These results can potentially be used to develop new types of inexpensive and energy-efficient devices.

New discovery by scientists redefines magnetism

Step into a world so tiny, it defies imagination -- the nanoscale. Picture a single strand of hair, now shrink it a million times. You've arrived. Here, atoms and molecules are the architects of reality, building properties and phenomena that challenge everything we thought we knew -- until now. Researchers have now unlocked a stunning discovery on this invisible frontier: a brand-new type of quasiparticle in all magnetic materials, no matter their strength or temperature. This groundbreaking find flips the script on magnetism, revealing it to be more dynamic than scientists once believed.

Fast, rewritable computing with DNA origami registers

DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are faster and smaller than today's silicon-based versions. As a step toward that goal, researchers report a fast, sequential DNA computing method that is also rewritable -- just like current computers.
