Medtronic plc secured CE mark approval under the EU Medical Device Regulation for its Brainsense adaptive deep brain stimulation system. The technology represents a major advancement in the treatment of Parkinson’s disease as it provides real-time, self-adjusting brain stimulation based on the patient’s brain activity, offering a more personalized therapy.

In the first patenting to emerge from Carlsbad, Calif.-based Biologic Input Output Systems Inc., its chief development officer, Timothy Miller, collaborated with academics on the development of implantable neural interfaces for placement in the peripheral nervous system.

Brainaurora Medical Technology Ltd. debuted on the Hong Kong stock exchange Jan. 8 with a HK$583.18 million (US$74.93 million) IPO, offering about 181.11 million shares at HK$3.22 per share.

2024 saw the completion of several cellular-resolution brain maps, including the entire fly brain and a comprehensive connections map of a cubic centimeter of human brain. 2025 began with the addition of another important map. In the Jan. 1, 2025, issue of Nature, researchers from the Allen Institute presented a map of areas and cell types where aging most affected the mouse brain.

Stressing the importance of integrity in taxpayer-funded biomedical research, the U.S. Department of Justice reported that Athira Pharma Inc. agreed to pay more than $4 million to resolve False Claims Act allegations that it failed to report potential research misconduct to the NIH and the Department of Health and Human Services’ Office of Research Integrity in grant applications and progress reports.

With more than 60 acquisitions completed in the last decade, Stryker Corp. shows little fear in committing to offers that allow it to obtain the companies and technologies that have driven its impressive growth in stock price – up from $92 in Jan. 2015 to $356.70 in Jan. 2025.

The success of checkpoint blockade, however, has not extended to all tumor types, but in 2024, molecular studies have led to advances in gene therapies and a multitude of approaches that have opened the door to hope.

2024 was another banner year for GLP-1 receptor agonists (GLP-1RAs) on multiple fronts. They continued to expand into new indications, and provide their developers with both rich remuneration and scientific acclamation. There are now seven approved GLP-1RAs.

AI pulled in major financings and approvals for Asia med-techs in 2024 as Asia Pacific countries played to individual strengths to maximize AI’s applications in the health care sector. While breakaway AI technologies like OpenAI’s ChatGPT reshaped and boosted many industries, AI also drove major financings for APAC med-techs weathering a wider macroeconomic downturn, with AI-based companies accounting for five out of 11 IPOs tracked on BioWorld’s med-tech IPOs list.

In the 1970s, scientists from several countries proposed to reconstruct, one by one, all the neurons in the brain as they appear under an electron microscope. They started with a small worm. Caenorhabditis elegans has only 302 neurons. It took 16 years. How much time would be required to repeat this arduous task for the 100 billion neurons in the human brain?
