Scientists find an exception in the Montreal Protocol for the use of ozone-depleting feedstocks could set the recovery of the ozone layer back seven years.
An international research team led by Satoshi N. Omura and Osamu Nureki from the University of Tokyo has engineered a novel variant of the Cas9 protein, a commonly used protein in gene editing technology, called “eSaCas9-NNG”. This novel variant surpasses other variants at all four key performance criteria. As such, it is expected to make a significant contribution to a wide array of applications, such as more precise and safer gene therapies. The findings were published in the journal Nature Communications.
Researchers have introduced an Ethereum-based fully distributed authentication mechanism that could significantly enhance security and efficiency in vehicular ad-hoc networks (VANETs), addressing long-standing challenges in certificate management, single points of failure, and real-time authentication latency. Published in Blockchain, this work presents EBDA, a novel framework that replaces traditional PKI certificate systems with a blockchain-maintained Graph of Trust (GoT), enabling certificate-free, fully decentralized identity authentication for vehicles.)
Metals such as titanium are prized for their strength, light weight, and resistance to corrosion, making them essential for aircraft, spacecraft, and medical implants. Now, a joint research team has developed a groundbreaking processing technique that dramatically improves the strength and toughness of titanium alloys—in just a few milliseconds.
