Researchers at the University of Sydney have uncovered a mechanism that may explain why glioblastoma returns after treatment, and the world-first discovery offers new clues for future therapies. Glioblastoma is one of the deadliest brain cancers, accounting for about half of all brain tumors, with a median survival rate of just 15 months.

Med-tech M&A value in 2025 totaled about $38.99 billion through November, reflecting a clear slowdown from 2024’s $57.92 billion and well below the peak years of 2021 and 2022, when 11-month totals exceeded $119 billion and $132 billion, respectively. Activity this year has been uneven, with a strong April ($9.04 billion) and July ($7.29 billion) accounting for a large share of the total, while several months posted relatively modest figures. November was particularly quiet, delivering just $5 million in M&A value, down sharply from $1.68 billion in October and marking the weakest month of the year.
