The Lake Tahoe communities of Christmas Valley and Meyers were spared during 2021's Caldor Fire. A UC Davis study reveals which pre-fire fuel treatments worked best to bring about the Christmas Valley "miracle."

Researchers at the University of Pittsburgh Swanson School of Engineering and Pitt’s School of Computing and Information have teamed up with scientists from Ames National Laboratory / Iowa State University, Boeing Research & Technology, and the Naval Nuclear Laboratory to demonstrate the potential of powerful quantum computers to solve real-world engineering problems.

A research team led by Prof. LI Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) eveloped a novel bromine-based two-electron transfer reaction system to overcome key limitations of conventional zinc–bromine flow batteries. By introducing amine compounds as bromine scavengers, the team converts corrosive bromine (Br₂) into brominated amines, reducing Br₂ concentration to ultra-low levels (~7 mM). This enables a two-electron redox process that increases energy density while significantly lowering electrolyte corrosivity.

At the core of each of our cells, the DNA molecule is constantly changing its configuration. When it twists or unfolds, it determines which genes are activated at each moment.

"We have shown that the way DNA twists is a layer of gene expression regulation that had previously gone unnoticed," says CNIO researcher Felipe Cortés.

Many breast cancers are treated by blocking oestrogens. Understanding on a molecular scale how this hormone works could help design better therapies, the authors suggest.
