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.

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.

Dr. Alice Stephant, an astrophysicist, is helping to solve a longstanding mystery about water on Earth: where it came from.

Scientists long thought that water, which covers 70% of the Earth, is probably rare or non-existent on other planets. The assumption was that water on Earth resulted from a unique series of galactic events billions of years ago.

Stephant, who works at the National Institute of Astrophysics in Italy’s capital Rome, is challenging these longstanding assumptions.

She has produced research that suggests the chemical components of water—hydrogen and oxygen—could have come from the giant cloud of dust and gas that gave rise to Earth’s solar system.

If water from that cloud could go directly into forming planets, it could...
