This week’s science roundup serves up two head-turners: researchers have identified a never-before-seen human blood type, which could revolutionize transfusions and prenatal care, while NASA’s Mars rover spotted eerie, web-like formations on the planet’s surface—raising questions about geological (or, who knows, maybe even biological?) processes at work. Plus, a few quirky reads to spice up your weekend.

Editor’s Note: The new blood type isn’t just a trivia tidbit—it could save lives by preventing dangerous immune reactions in medical procedures. And those Martian "spiderwebs"? They’re a reminder that our neighboring planet still holds mysteries that could reshape how we understand the universe. Science isn’t just about textbooks; it’s unfolding in real time, with stakes that feel thrillingly human.
