The first day of the U.S. FDA’s two-day advisory hearing on generative artificial intelligence reflected some of the anxieties attached to this emerging technology, with the phenomenon of hallucinations driving several calls for more stringent regulation of this class of products that might be applied toward other entries in the class of artificial intelligence.

Many studies have linked the presence of specific bacteria to various diseases. But a general overgrowth of gut bacteria can be a symptom of different conditions, including colorectal cancer and inflammatory bowel disease.

An international consortium of thousands of scientists is creating the Human Cell Atlas, a three-dimensional map of all the cells in the body. The goal is to understand all the cells that make up human tissues, organs and systems, which will enable multiple medical applications. This collection of cell maps is openly available for navigation at single-cell resolution, identified through omics analyses that reveal the tridimensional distribution of each cell.

The development of new machine learning tools like Alphafold and Rfdiffusion has allowed scientists to predict the structure of proteins and design them for drug discovery purposes, among other uses. Now, scientists at the Arc Institute have created Evo, an AI model that generates DNA sequences and estimates their interaction with other molecules at single-nucleotide resolution, scalable to an entire genome.

Many studies have linked the presence of specific bacteria to various diseases. But a general overgrowth of gut bacteria can be a symptom of different conditions, including colorectal cancer and inflammatory bowel disease. A study counting gut microbiome proposes that microbial load, rather than the disease, could explain the presence of certain pathogens.

Device makers are not necessarily fond of the need to acquire Medicare coverage by picking off one Medicare administrative contractor at a time, but Cleerly Labs Inc. worked this path with gusto.

Abstract ideas are not generally eligible for patents in the U.S., but a recent dispute heard by the U.S. Patent Trial and Appeal Board adds a new twist to the question.

The U.S. FDA has had its sights on artificial intelligence (AI) for some time, but an upcoming advisory hearing will review questions such as the regulatory status of a generative AI (GenAI) algorithm. This is just one of several AI-related dilemmas facing the agency in the next few years.
