Strange pits on 2 million-year-old teeth may reveal which human relatives are closely related to each other

NASA’s GOLD mission stumbled onto something unexpected—bizarre X-shaped structures hanging out in Earth’s ionosphere, way up where satellites live. The real kicker? These shapes showed up during quiet space weather, defying the old assumption that they only appeared during solar storms. It’s a head-scratcher that could rewrite how we understand the upper atmosphere, with real-world ripple effects for things like GPS and radio signals.

Editor’s Note: Think of this like finding a hidden rulebook for Earth’s sky-high borderlands. If the ionosphere—a critical layer for tech we rely on daily—is behaving in ways we didn’t predict, it could mean tweaks for how we manage communications, navigation, and even space weather forecasts. Plus, it’s a reminder that Earth still has plenty of mysteries left to solve.

Scientists just got their clearest look yet at the sun’s wild magnetic activity, thanks to the ultra-powerful Daniel K. Inouye Solar Telescope. The new images show incredibly detailed bright and dark stripes—like tiny "magnetic curtains"—rippling across the solar surface. These striations are caused by intense magnetic fluctuations, giving researchers a front-row seat to the sun’s chaotic energy in action.

Editor’s Note: Understanding these magnetic patterns isn’t just about pretty pictures—it helps us predict solar storms that can mess with satellites, power grids, and even your GPS. The better we grasp the sun’s behavior, the better we can shield our tech (and ourselves) from its tantrums. Plus, it’s a reminder of how much we’re still learning about our own star.

If you're in parts of the northern and central U.S., you might get a rare celestial treat tonight or this weekend—the northern lights could be visible as far south as Wyoming. A surge of solar activity is creating ideal conditions for auroras, turning the night sky into a potential light show for residents in 18 states.

Editor’s Note: Seeing the northern lights is usually a bucket-list experience that requires a trip to places like Iceland or Alaska, but this geomagnetic storm is bringing that magic closer to home for millions. It’s a reminder of how connected we are to the sun’s activity—and a great excuse to step outside and look up.

Move over, human dads—Djungarian hamster fathers are stepping into the spotlight this Father’s Day for their surprisingly hands-on parenting. Unlike many rodent species where dads are absent or uninvolved, these tiny furballs actively help raise their pups, from grooming to keeping them warm. It’s a rare and heartwarming example of paternal care in the animal kingdom.

Editor’s Note: This isn’t just a cute animal fact—it challenges assumptions about parenting roles in nature. Djungarian hamsters remind us that caregiving isn’t always a mom’s job, even in species where that’s the norm. For scientists, their behavior could offer clues about the evolution of parental roles. For the rest of us? It’s a wholesome excuse to appreciate the underrated dads of the animal world.

Scientists are turning to space to unlock new insights into cancer. The harsh conditions of microgravity and radiation—usually harmful to astronauts—might actually help researchers study how cancer cells behave differently than on Earth. This could lead to breakthroughs in understanding and even treating the disease.

Editor’s Note: It sounds like sci-fi, but space isn’t just for exploration—it could be a game-changer for medical research. Since cancer cells act strangely in microgravity, studying them off-Earth might reveal secrets we’d never spot in a lab here. If this pans out, it could fast-track treatments or even prevention strategies, making the cosmos an unexpected ally in the fight against cancer.
