Remote Control of Blood Sugar: Electromagnetic Fields treat Diabetes in Animal Models

Study suggests EMFs alter redox signaling to improve insulin sensitivity. Researchers from the University of Iowa may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes two major hallmarks of type 2 diabetes, according to new findings published Oct. 6 in Cell Metabolism.

“We’ve built a remote control to manage diabetes,” says Calvin Carter, PhD, one of the study’s lead authors and a postdoc in the lab of senior author Val Sheffield, MD, PhD, professor of pediatrics, and of ophthalmology and visual sciences at the UI Carver College of Medicine...

New Algorithm could Unleash the Power of Quantum Computers

A new algorithm leaps past limits restricting quantum computers.
A new algorithm leaps past limits restricting quantum computers.

Fast-forwarding quantum calculations skips past the time limits imposed by decoherence, which plagues today’s machines. A new algorithm that fastforwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.

“Quantum computers have a limited time to perform calculations before their useful quantum nature, which we call coherence, breaks down,” said Andrew Sornborger of the Computer, Computational, and Statistical Sciences division at Los Alamos National Laboratory, and senior author on a paper announcing the research...

Sensor with 100,000 times Higher Sensitivity could Bolster Thermal Imaging

The graphene bolometer sensor detects electromagnetic radiation by measuring the temperature rise as the photons are absorbed into the sensor. Graphene is a two dimensional, one-atom layer thick material. The researchers achieved a high bolometer sensitivity by incorporating graphene in the microwave antenna.

Better detection of microwave radiation will improve thermal imaging, electronic warfare, radio communications. Army-funded research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar.

Researchers published their study in the peer-reviewed journal Nature...

Quantum Entanglement realized between Distant Large Objects

Quantum entanglement realized between distant large objects
Light propagates through the atomic cloud shown in the center and then falls onto the SiN membrane shown on the left. As a result of interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. This is the essence of entanglement between the atoms and the membrane.

A team of researchers at the Niels Bohr Institute, University of Copenhagen, have succeeded in entangling two very different quantum objects. The result has several potential applications in ultra-precise sensing and quantum communication and is now published in Nature Physics.

Entanglement is the basis for quantum communication and quantum sensing...
