Scientists have found that gently zapping the brain with electricity might give your math skills a little boost—especially if you struggle with numbers. The study highlights that people with weaker connections in a specific brain region saw the most improvement after controlled electrical stimulation. It’s not a magic fix, but it’s a promising peek into how we might enhance learning in the future.

Editor’s Note: Math anxiety or struggles are real for a lot of people, and this research opens up a fascinating—if slightly sci-fi—avenue for helping them. While we’re not at "brain-zapping homework sessions" just yet, it’s a step toward understanding how targeted brain stimulation could support learning. For anyone who’s ever felt stuck on numbers, that’s pretty exciting.

The Senate’s latest draft of Trump’s policy bill is rolling back several key clean energy tax credits, a move that could slow the growth of renewable energy projects. While supporters argue it streamlines the tax code, critics warn it undermines efforts to combat climate change and could hurt jobs in the green energy sector.

Editor’s Note: This isn’t just about tax breaks—it’s a signal of where the U.S. might be heading on climate action. Cutting these incentives could make renewables less competitive, potentially keeping fossil fuels dominant for longer. If you care about clean energy jobs or the pace of decarbonization, this is a big deal.

Turns out wild orcas—those massive, intelligent ocean predators—sometimes share their meals with humans. This isn’t trained behavior like you’d see at SeaWorld; it’s something they do on their own, unprompted. Scientists are still figuring out why, but it’s a rare and fascinating glimpse into how these animals interact with us.

Editor’s Note: Most of the time, we think of wild predators as dangerous or indifferent to humans. But this kind of unexpected generosity from orcas (who aren’t even domesticated!) challenges that assumption. It’s a reminder that animals—especially highly social, intelligent ones—might have more complex relationships with us than we realize. Plus, it’s just cool to imagine a killer whale casually handing you a fish.

On July 2, skywatchers will get a rare treat—a giant "X" and "V" will appear on the moon's surface, thanks to the way sunlight hits its craters and ridges. It’s not actual markings, just a cool trick of shadows and angles. If you’ve got clear skies and a decent view, you might catch this fleeting spectacle with binoculars or a small telescope.

Editor’s Note: This isn’t just another pretty sky event—it’s a neat reminder of how simple celestial mechanics can create something that feels almost designed. For amateur astronomers or even casual stargazers, it’s a low-effort way to feel connected to the cosmos. Plus, it’s a fun excuse to look up from your phone and enjoy the night sky.

If you're looking for a solid Bluetooth speaker to take your tunes anywhere—whether it's a backyard BBQ or a camping trip—this roundup has you covered. Popular Science tested and reviewed the top portable options for 2025, so you don’t have to guess which one’s worth your cash.

Editor’s Note: Let’s face it, nobody wants to lug around a clunky speaker or deal with sketchy sound quality. This list cuts through the noise (literally) and highlights the best picks for hassle-free, on-the-go audio. Handy if you’re gearing up for summer adventures or just hate settling for tinny phone speakers.
