New Nevada experiments will improve monitoring of nuclear explosions

Physics General News

02 May 2024

On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world....

Nanotubes, nanoparticles and antibodies detect tiny amounts of fentanyl

Nanotechnology News

02 May 2024

A research team at the University of Pittsburgh led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich School of Arts and Sciences, has developed a fentanyl sensor that is six orders of magnitude more sensitive than any electrochemical sensor for the drug reported in the past five...

Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter

Quantum Physics News

02 May 2024

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials....

Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer

Nanotechnology News

02 May 2024

Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltrate that cancerous fortification and deliver these...

Physicists arrange atoms in extremely close proximity

Physics General News

02 May 2024

Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of...
