New ‘AI scientists’ are improving—but reveal their fundamental limits
Many of the most exciting discoveries in science involve highly specialized knowledge and making connections between far-flung facts. Scientists must combine deep analysis with broad reasoning strategies.
As in many information-rich tasks, researchers are looking to artificial intelligence (AI) systems to speed up their work. AI tools may be able to support key steps such as generating ideas, reviewing existing work and analyzing data.
The latest systems use large language models (LLMs) to allow scientists to interact naturally and directly with the vast body of knowledge captured in words in the scientific literature.
Human monoclonal antibodies that target the SFTSV glycoprotein Gn head from four neutralizing epitope groups
Wang et al. report that Gn-specific mAbs from SFTS survivors exhibit broad and potent neutralization, with two providing complete protection in a lethal mouse model. This work maps the Gn antigenic landscape and establishes a deep mutational scanning platform coupled with structural validation for bunyavirus antibody discovery.
China’s lab-grown heart organoid could offer alternative to pacemakers
A team of scientists in Shanghai has developed a lab-grown biological pacemaker designed to mimic the heart’s natural rhythm control system. By working with human pluripotent stem cells, which can transform into many different types of tissue, the researchers created a three-dimensional sinoatrial node organoid capable of generating electrical impulses, the South China Morning Post reported.
To make the system more lifelike, the team linked the organoid to an artificial cardiac plexus, a network of nerves located near the base of the heart that helps regulate heartbeat activity. The achievement allowed researchers to recreate how the nervous system communicates with the heart, opening potential new paths for studying irregular heart rhythms and developing future treatments that could reduce reliance on electronic pacemakers.
The research, published in the journal Cell Stem Cell involved scientists from the Chinese Academy of Sciences and Fudan University. The team focused on the sinoatrial node, the tiny part of the heart responsible for controlling its rhythm. Although it plays a critical role in keeping the heart beating properly, the structure has been difficult for scientists to study because of its small size and hard-to-reach location inside the heart.
