The public, legislators, and media often group per- and polyfluoroalkyl substances, known as PFAS or “forever chemicals,” which are found globally in countless products, into a single category. While certain PFAS are harmful for human and public health, new articles in Heart Rhythm, the official journal of the Heart Rhythm Society, the Cardiac Electrophysiology Society, and the Pediatric & Congenital Electrophysiology Society, published by Elsevier, emphasize that fluoropolymers, a specific class of PFAS, are not considered environmental contaminants and are indispensable for use in medical devices. Experts call for a balanced approach to protect both the environment and availability of essential medical technologies.

Kyoto, Japan -- Experts say quantum computing is the future of computers. Unlike conventional computers, quantum computers leverage the properties of quantum physics such as superposition and interference, theoretically outperforming current equipment to an exponential degree.

When a quantum computer is able to solve a problem unfeasible for current technologies, this is called the quantum advantage. However, this edge is not guaranteed for all calculations, raising fundamental questions regarding the conditions under which such an advantage exists. While previous studies have proposed various sufficient conditions for quantum advantage, the necessity of these conditions has remained unclear.

Motivated by this uncertainty, a team of researchers at Kyoto University has endeavored to understand the necessary and sufficient conditions for quantum advantage, using an approach combining techniques from quantum computing and cryptography, the science of coding information securely.

A new study led by FAMU-FSU College of Engineering researchers investigating precision polymer blends revealed critical insights that could accelerate the development of advanced materials for batteries, membranes and energy storage systems.

The research, which focused on blends of a polymer called polyethylene oxide (PEO) and a charged polymer known as p5, found that even small amounts of charge can dramatically alter how these materials mix. This behavior aligns with previously developed theoretical models, offering a new framework for anticipating when polymer blends will remain uniform or separate into distinct phases.
