Although it does not generally infect humans, a single mutation of the H5N1 virus in the highly pathogenic avian and bovine clade 2.3.4.4b could overcome this barrier and possibly trigger a pandemic. Scientists at The Scripps Research Institute have warned of this possibility after studying the three-dimensional structure of the viral hemagglutinin and seeing how a change in one amino acid would make it more suitable for the human cell receptor. The researchers stress the need to monitor new mutations of this virus in order to act quickly in case the global jump to our species occurs.
In breast cancer, neoadjuvant chemotherapy reduces the tumor before surgery. However, the response to this treatment does not depend solely on the subtype of malignancies. Other factors could play a key role in its effectiveness, as shown in a study that described how the estrous cycle phases contribute to this variation.

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.
At the Breakthroughs in Muscular Dystrophy special meeting held in Chicago Nov. 19-20, 2024, and organized by the American Society of Gene & Cell Therapy (ASGCT), multiple interventions at the RNA level were among the approaches that were presented to fight muscular dystrophies.
Since the isolation of the gene that causes Duchenne muscular dystrophy (DMD), scientists have progressed in understanding the mechanisms that lead to muscular diseases that can be evident from the early stages of childhood. This has led to the development of diagnostics and therapeutics, some approved by the FDA.
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.

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.
