Chinese researchers are preparing the details for the publication of another scientific milestone, the creation of a chimera with a human heart and a kidney developed from human stem cells in pig embryos.

Researchers from Virginia Polytechnic Institute and State University filed for protection of their development of a slim, painless, and affordable microfluidic infusion pump device for the continuous transdermal delivery of drugs.

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

A collaboration of scientists from the NIH Brain Initiative consortium has published eight simultaneous studies in Neuron, Cell, Cell Genomics, Cell Reports and Cell Reports Methods, with the results of the Armamentarium project, a new set of gene therapy tools for the research and treatment of human brain disorders. The methodology, based on genetic techniques, RNA detection, genomic enhancers and viral vectors, is designed to access different CNS cell types, neuronal and non-neuronal cells, with common and reproducible protocols now available for any laboratory.

In a roadmap to change animal testing requirements for INDs, the U.S. FDA said its new approach will improve drug safety, hasten the evaluation process, and lower costs for companies and patients. It’s another step in a process of changing rules put in place decades ago.

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.

The three-dimensional analysis of cell types and their locations by spatial transcriptomics provides key information of their interactions within tissues or organs. Based on this technology, scientists at the Wellcome Sanger Institute have developed an AI tool called Nichecompass, which shows a comprehensive view of the cancer microenvironments, the different cells, their locations, and how they communicate with each other through different molecules inside the tumor.

Medtronic plc reported results from a registry highlighting the effectiveness of the Prevail paclitaxel-coated balloon. The findings from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) were presented by Sacharias von Koch of the department of cardiology and clinical sciences at Lund University, Skåne University Hospital in Sweden at the Cardiovascular Research Technologies 2025 meeting in Washington.

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.

A recent patent filing from Verily Life Sciences LLC seeks protection for the development of an ophthalmic drug delivery device with sensors and a camera which allow the delivery of a specific or controlled dose of a therapeutic agent in vapor form to a patient’s eye.
