In two-dimensional quantum materials, chiral edge states are one-dimensional conducting channels through which electrons travel in one direction only, like cars on a one-way road. This is because chirality is a special form of asymmetry. Imagine a material like a sheet of paper. A chiral edge state is like a flow of electrons along the edge of the paper. Chiral means that if the electrons flow from left to right on one edge, then they flow from right to left on the opposite edge. Under these conditions electron collisions are strongly suppressed because they cause electrons to change direction, which is not allowed on a one-way chiral edge “road.” These collisions are the primary cause of electrical resistance in wires, so chiral channels act like highly efficient resistance-free conductors. Researchers have created chiral edge states in atomically thin devices made of three graphene layers. They used a scanning tunneling microscope (STM) to image the chiral channels with atomic resolution.

BINGHAMTON, N.Y. -- When ChatGPT and other generative artificial intelligence can produce scientific articles that look real — especially to someone outside that field of research — what’s the best way to figure out which ones are fake?.

Analyzing and simulating fluid flow is a challenging mathematical problem that impacts various scenarios, including video game engines, ocean current modeling and hurricane forecasting. The core of this challenge lies in solving the Navier–Stokes equations, a set of classical equations that describe fluid dynamics. Recently, deep learning has emerged as a powerful tool to accelerate equation solving. Using this technique, a team designed a novel approach that can provide accurate solutions 1,000 times faster than traditional equation solvers. The team’s study was published June 26 in Intelligent Computing, a Science Partner Journal.

The most frequently used mpox vaccine provides partial immunity to the disease but isn’t always able to prevent severe symptoms or disease transmission. A new vaccine candidate from Moderna, mRNA-1769, more effectively limits symptoms and disease duration in primates that were infected with a lethal strain of the mpox virus when compared to a currently licensed modified vaccinia Ankara (MVA) vaccine. The study publishes September 4 in the Cell Press journal Cell.

WASHINGTON, D.C. - Today, the U.S. Department of Energy (DOE) announced $125 million in funding for two Energy Innovation Hub teams to provide the scientific foundation needed to seed and accelerate next generation technologies beyond today’s generation of lithium (Li)-ion batteries. These multi-institution research teams, led by Argonne National Laboratory and Stanford University, will develop scientific concepts and understanding to impact decarbonization of transportation and incorporation of clean energy into the electricity grid.

But over the past decades, evolutionary mathematicians have used game theory to better understand why mutual cooperation persists when evolution should favour self-serving cheaters.
