Can adults make new brain cells? New study may finally settle one of neuroscience's greatest debates

Ninja's FrostVault cooler, which has a handy dry drawer to keep food from getting soggy while chilling drinks, is currently on sale at Amazon for its lowest price ever. It’s a solid pick for summer gatherings where you want to keep things cold without the usual cooler mess.

Editor’s Note: With summer in full swing, deals like this make it easier to upgrade your outdoor gear without breaking the bank. The FrostVault’s clever design solves a common annoyance (wet food in coolers), so the discount is especially appealing for anyone hosting barbecues or beach trips. It’s one of those small but smart innovations that can actually make a difference in your day-to-day convenience.

Astronomers have spotted only the third known object from another star system cruising through our solar system—a comet named 3I/ATLAS (previously cataloged under the clunkier name A11pI3Z). These interstellar visitors are rare, making each discovery a big deal for scientists trying to understand how stuff moves between star systems.

Editor’s Note: Finding interstellar objects is like stumbling across cosmic messages in a bottle—they give us clues about how planetary systems form beyond our own. This comet, like ‘Oumuamua and Borisov before it, might carry hints about the chemistry or physics of distant stars, and every new one helps piece together the bigger picture of our galaxy’s "interstellar traffic." Plus, it’s just cool to know we’re not entirely alone out here, even if it’s just a hunk of ice passing through.

Over 70 authors—including some big names—have banded together to call out the publishing industry on AI. Their open letter draws a hard line: no machine-written books, ever. They’re worried about AI diluting human creativity and possibly even stealing their livelihoods.

Editor’s Note: This isn’t just about robots writing bad poetry—it’s a real fight over who gets to shape culture. If publishers start leaning on AI, it could change what (and who) gets published, squeezing out human voices. Writers are making it clear: they won’t quietly hand over the pen.

A fresh study might have just cracked a long-standing neuroscience puzzle: whether adult brains can grow new neurons. After years of back-and-forth debates, researchers now claim they’ve got solid proof that our brains keep producing fresh nerve cells well into adulthood—a discovery that could reshape how we understand aging, memory, and even mental health treatments.

Editor’s Note: This isn’t just academic drama—it’s a big deal for anyone who’s ever worried about brain decline. If adult brains can generate new cells, it opens doors for therapies targeting Alzheimer’s, depression, or just keeping sharp as we age. Plus, it’s a win for lifelong learning; your brain might be more adaptable than we thought.

Think of the universe's most massive stars as the wild, over-the-top rock stars of space—they burn bright, go out with a bang, and leave behind something mysterious (in this case, black holes). New research suggests these stars might "vomit" way more material into space than we previously thought before their dramatic collapse.

Editor’s Note: This isn't just a cool cosmic fact—it could change how we understand the life cycles of stars and how black holes form. If these stars are ejecting more matter than expected, it might reshape our models of how elements spread through the universe. Plus, who doesn’t love a good "space vomit" metaphor?
