Researchers at the University of East Anglia have proposed a new way of using quantum light to ‘see’ quantum sound.

A new paper published today reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules.

It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales.

And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.

Dr Magnus Borgh from UEA’s School of Physics said: “There is a long-standing controversy in chemical physics about the nature of processes where energy from particles of light is transferred ...

Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen — casting new light on how heavy elements are made.

Researchers examined the exceptionally bright gamma-ray burst GRB 230307A, which was caused by a neutron star merger. The explosion was observed using an array of ground and space-based telescopes, including NASA’s James Webb Space Telescope, Fermi Gamma-ray Space Telescope, and Neil Gehrels Swift Observatory.

Publishing their findings today in Nature(25 Oct), the international research team which included experts from the Univ...

Researchers Identify ‘Switch’ to Activate Cancer Cell Death

A graphic shows two circles in blue and gold representing tumor cells and a red circle representing CAR-T immunotherapy.
An antigen-negative tumor cell, shown in the golden color on the right, is killed by Fas-mediated “bystander” killing.

A research team from the UC Davis Comprehensive Cancer Center has identified a crucial epitope (a protein section that can activate the larger protein) on the CD95 receptor that can cause cells to die. This new ability to trigger programmed cell death could open the door for improved cancer treatments. The findings were published Oct. 14 in the Nature journal Cell Death & Differentiation.

CD95 receptors, also known as Fas, are called death receptors. These protein receptors reside on cell membranes. When activated, they release a signal that causes the cells to self-destruct.

Modulating Fas may also extend the benefits of chimeric antigen receptor (CAR) T-cell th...

Intelligent robots are reshaping our universe. In New Jersey’s Robert Wood Johnson University Hospital, AI-assisted robots are bringing a new level of security to doctors and patients by scanning every inch of the premises for harmful bacteria and viruses and disinfecting them with precise doses of germicidal ultraviolet light.

In agriculture, robotic arms driven by drones scan varying types of fruits and vegetables and determine when they are perfectly ripe for picking.

The Airspace Intelligence System AI Fly...
