Researchers hope the technique could one day be used before surgery, childbirth and other events that…

Why are some countries richer than others? The 2024 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel has been awarded to three researchers who have helped shed light on this fundamental question. The income gap between the richest and the poorest nations has been widely documented. However, Daron Acemoglu and Simon Johnson,…

If programs like 3-2-1 Contact or Zoboomafoo opened your mind to how the world works around you, you’ll enjoy PBS’s contemporary offerings of all things science. Episodes of the programs below can mostly be discovered via the PBS app or pbs.org, with new episodes of many airing regularly; shows created locally by Iowa PBS are…

Abstract Climate over land—where humans live and the majority of food is produced—is changing rapidly, driving severe impacts through extreme heat, wildfires, drought and flooding. Our ability to monitor and model this changing climate is being transformed through new observational systems and increasingly complex Earth system models. But fundamental understanding of the processes governing land…

Abstract The rapid advancement of artificial intelligence (AI) is poised to reshape almost every line of work. Despite enormous efforts devoted to understanding AI’s economic impacts, we lack a systematic understanding of the benefits to scientific research associated with the use of AI. Here we develop a measurement framework to estimate the direct use of…

Researchers have used artificial intelligence (AI) to uncover 70,500 viruses previously unknown to science1, many of them weird and nothing like known species. The RNA viruses were identified using metagenomics, in which scientists sample all the genomes present in the environment without having to culture individual viruses. The method shows the potential of AI to…

WORCESTER – The EcoTarium Museum of Science and Nature, at 222 Harrington Way, announced its first expansion since 2000, with the addition of a a new 8,300 square foot Traveling Exhibit Gallery. The addition will add 6,300 square feet of gallery space and 2,00 square feet of related support spaces. The EcoTarium says the expansion will…

Tasks such as literature review can be made easier with AI tools, but the tools must be used with caution.Credit: Olena Hromova/Alamy Artificial-intelligence (AI) tools are transforming the way we work. Many products attempt to make scientific research more efficient by helping researchers to sort through large volumes of literature. These scientific search engines are…
