Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules called microRNAs to attack multiple cancer-driving genes simultaneously.

Scientists discover metals that defy the deep freeze at -424°F
Scientists have discovered a surprising mechanism that allows certain metals to resist cracking at temperatures as low as -253°C (-424°F), when similar materials typically become dangerously brittle. Instead of breaking, two experimental alloys reorganize their internal structure
