New research from Oregon Health & Science University could one day lead to therapies that prevent or treat diseases and infections tied to a protein that’s found in all human cells.

A study published today in the journal Molecular Cell describes how the protein ubiquitin is modified during bacterial infection.

The study details the steps taken to create a form of the protein known as lysine 6 polyubiquitin, where a long chain of ubiquitin molecules are linked through the amino acid lysine. This form of ubiquitin helps cells communicate by sending a molecular message—communication that remains poorly understood.

US Customs and Border Protection (CBP) recently awarded Pangiam, a leading trade and travel technology company, a prime contract for developing and implementing Anomaly Detection Algorithms (ADA).

Pangiam, in collaboration with West Virginia University, aims to bring cutting-edge artificial intelligence (AI), computer vision, and machine learning expertise to enhance CBP’s border and national security missions, the company announced in a press release.

“In the study, we demonstrate how artificial intelligence can be used to carry out fundamental theoretical physics that addresses the behavior of fluids and other complex soft matter systems,” says Prof. Dr. Matthias Schmidt, chair of Theoretical Physics II at the University of Bayreuth.

Scientists from Bayreuth have developed a new method for studying liquid and soft matter using artificial intelligence. In a study now published in the Proceedings of the National Academy of Sciences, they open up a new chapter in density functional theory.

We live in a highly technologized world where basic research is the engine of innovation, in a dense and complex web of interrelationships and interdependencies. The published research provides new methods that can have a great influence on widespread simulation techniques, so that complex substances can be investigated on computers more quickly, more precisely and more deeply.

Google thinks that there’s an opportunity to offload more healthcare tasks to generative AI models — or at least, an opportunity to recruit those models to aid healthcare workers in completing their tasks.

Google has unveiled MedLM, a new family of generative AI models designed to tackle healthcare-related tasks.

When it comes to spurring the development of cutting-edge technologies, the Chinese government is rather pragmatic in its policymaking process. In the field of autonomous driving, the country has made some big strides in defining the parameters and limitations for service providers, removing regulatory ambiguity and granting industry players the freedom to test the nascent technology.

The trial guidelines, unveiled by the Ministry of Transport recently, target AV services like robotaxis, self-driving trucks and robobuses. The release arrived about 16 months after the department began seeking public opinions on the regulatory framework, and policymakers have reached a consensus that self-driving vehicles are subject to rigorous surveillance measures to ensure utmost safety.

Prior to the introduction of the nationwide guidelines, policymaking for AVs in China had been playing out in a more decentralized fashion, with local governments formulating their own rules for service providers on their turf. Major tech clusters like Beijing, Shenzhen and Guangzhou, for example, have been frontrunners in allowing companies to test AVs with minimum human interference.
