New technique promises clearer, more frequent views of black holes

The Trump administration's travel restrictions are preventing foreign medical professionals—many of whom are already approved to work in U.S. hospitals—from entering the country. At a time when healthcare systems are stretched thin due to the pandemic, these policies could worsen staffing shortages, leaving hospitals without much-needed doctors and nurses.

Editor’s Note: This isn't just about immigration rules—it's about real-world consequences for hospitals already struggling to keep up. Blocking trained medical workers from filling critical gaps could mean longer wait times, overworked staff, and even worse patient outcomes. In a crisis, bureaucracy shouldn't get in the way of saving lives.

Amazon just slashed prices on Canon’s high-end mirrorless cameras, knocking at least $100—and in some cases hundreds—off the usual cost. If you’ve been eyeing an upgrade or jumping into professional photography, this is a rare chance to save big.

Editor’s Note: Mirrorless cameras are a game-changer for photographers, but their steep prices can be a barrier. This drop makes pro-level gear more accessible, whether you’re a hobbyist looking to level up or a pro hunting for a backup body. Timing matters—these deals won’t stick around forever.

Scientists think the secret to our big brains might be hiding in the womb—specifically, in the flood of placental sex hormones human fetuses are bathed in. Unlike other primates, we get a much heavier dose of these hormones during pregnancy, and that could’ve turbocharged our brain evolution. It’s a fascinating twist on the "why are we so smart?" question, suggesting our cognitive edge might start with biology before birth.

Editor’s Note: This isn’t just a nerdy detail about hormones—it reshapes how we understand what makes humans unique. If placental hormones really did supercharge our brains, it connects the dots between reproduction, development, and intelligence in a way we’ve never fully appreciated. Plus, it hints that the roots of human brilliance might be more biological than we thought, tucked deep in our evolutionary history.

NASA has hit pause on the Axiom Mission 4 launch to the International Space Station (ISS), where Indian astronaut Shubhanshu Shukla was set to make history. The delay comes as engineers double-check recent repairs on the Zvezda service module—essentially making sure the ISS is in tip-top shape before welcoming the new crew, which also includes astronauts from Poland and Hungary. A new launch date is expected soon, but for now, safety takes priority.

Editor’s Note: Delays in space missions are frustrating, especially for high-profile launches like this one, but they’re also a reminder of how seriously NASA takes astronaut safety. For Shukla and his international crewmates, it’s a temporary setback—better to wait than risk a problem in orbit. The story also highlights the growing global collaboration in space, with India, Poland, and Hungary all part of this mission. Patience is key when it comes to space travel.

Turns out, Mars isn’t quite as red as it seems—at least not all the time. A physicist breaks down why the planet’s famous rusty hue can look different depending on how you’re observing it, whether through a telescope, a rover’s camera, or even the naked eye. The color shifts come down to dust, light, and a sprinkle of cosmic illusion.

Editor’s Note: Mars has always been this mysterious red dot in the sky, but this piece peels back the curtain on why its color isn’t as straightforward as we think. It’s a cool reminder that even the simplest things—like a planet’s color—can have layers of science behind them. Plus, it’s a neat example of how perspective (and technology) shapes what we “know” about space.
