Researchers have engineered a multifunctional gallium-doped bioactive glass that selectively kills osteosarcoma cells and prevents bacterial infections while promoting bone regeneration. By localized delivery of gallium ions, this innovative biomaterial disrupts iron metabolism in cancer cells, triggering programmed cell death without harming healthy bone tissue. It simultaneously provides a robust defense against hospital-acquired pathogens like Pseudomonas aeruginosa.
AI-powered conversational tools are becoming a common source of emotional support for teenagers. But without safeguards and careful design, reliance on these systems may bypass opportunities for young people to develop critical relationship skills through person-to-person interactions.
Ozone depletion began decades before discovery of ozone hole, MIT scientists have found. Using modern tools, they also determined that carbon tetrachloride, a common dry-cleaning and degreasing agent, was at the root of early ozone loss.
Wave energy has long been seen as a promising source of clean electricity. The ocean is always moving, and that motion carries a huge amount of energy. But many wave energy devices have one important limitation: they do not naturally move in sync with ocean waves. When that happens, they capture less power.
Researchers from ESPOL, Stevens Institute of Technology, and partner institutions tested a simple passive way to tune a wave energy device so it can respond better to changing sea conditions. Their idea uses submerged cones attached to the sides of a floating platform. As the platform moves, the cones trap water and change the system’s motion, helping it adjust more naturally to long ocean swells.
