An experimental drug for treating diabetes and obesity has been shown to lower blood sugar levels and increase fat burning. It is a β2-adrenergic receptor (β2AR) agonist that mimics the effects of physical exercise by activating skeletal muscle metabolism. Unlike GLP-1-based treatments such as semaglutide and tirzepatide, this new compound, developed by researchers at the Karolinska Institute, Stockholm University, and the biotech company Atrogi AB, does not suppress appetite or cause muscle loss. 

Microneedle technology could help simplify vaccine delivery to better support global immunization efforts, and Australia is leading the way in this innovative technology.

“I’m a pediatrician in metabolic diseases, and every day in my clinical work I’m confronted with our lack in effective therapies for our patients.” That was the sobering introduction by Sabine Fuchs in her talk at the 2025 Congress of the European Association for the Study of the Liver in Amsterdam this week. The nature of metabolic diseases makes it difficult to develop treatments for them. “There are over 1,500 diseases known by now, and it is just very difficult to develop therapies for each and every individual rare disease.”

Transplanting an animal organ into a human is now a closer reality following the successful xenotransplantation of a genetically modified pig liver into a patient diagnosed with brain death in China. The operation was intended to evaluate organ function over a 10-day period. This is a complex experimental trial that did not involve removing the patient's liver and still requires further study. However, the positive preclinical results suggest this strategy could save the lives of those waiting for a human organ, at least in certain cases.

In an advance that could significantly lighten the load for caretakers in the “sandwich generation” and reduce loneliness in elderly patients, Aspargo Labs Inc. developed a metered delivery device that optimizes absorption of pharmaceuticals and reminds users to take their medications.

Researchers have altered the genetic code in a strain of Escherichia coli, reducing the number of stop codons from three to one and assigning the freed-up stop codons to nonstandard amino acids. They reported on the recoded bacterium, which they named OCHRE, in Nature on Feb. 5, 2025.

Following Nobel Prize-winning chemist David Baker’s recipe for cooking an antidote to cobra venom using artificial intelligence (AI) could be faster and more effective than currently available methods. The ingredients and steps can be found in a new study published by the University of Washington scientist in collaboration with the Technical University of Denmark. They are ready for the next steps in preclinical trials.

Researchers from the University of California San Francisco (UCSF) have successfully replicated the design of regulatory T cells, achieving local targeted immune suppression and protection from CAR T-cell cytotoxicity. Many of the treatments used so far in the context of inflammatory and autoimmune disorders lead to systemic immunosuppression. In this sense, limiting immunosuppression locally to targeted tissues may help overcome systemic toxicity.

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.
