Welcome to Science News Daily, your source for the latest discoveries from the world of science. I'm [Host Name], and today we're diving into some fascinating developments that are reshaping our understanding of the universe and life itself.

Let's start with a stellar mystery that's puzzling astronomers. The Keck Observatory in Hawaii has detected unexpected signals from a nearby star that are challenging our long-standing models of stellar behavior. Using the Keck Planet Finder to study faint vibrations within stars, scientists have discovered internal features that simply don't match what we thought we knew about how stars work. It's discoveries like these that remind us how much we still have to learn about the cosmos.

Speaking of cosmic revelations, Chinese scientists have unveiled what they're calling a galactic treasure map. The Large High Altitude Air Shower Observatory, or LHAASO, has captured ultrahigh-energy gamma-ray emissions across the Milky Way in unprecedented detail. This mini survey of our galaxy is opening a new window to the extreme universe, revealing powerful cosmic phenomena that were previously hidden from view.

In a truly remarkable astronomical achievement, researchers have captured the first-ever image of a star that exploded twice. This white dwarf underwent what's called a double-detonation supernova, where an initial helium blast on the star's surface triggered a second, core-shattering explosion. The remnant they studied, known as SNR 0509-67.5, is providing crucial insights into these rare cosmic events.

Now, shifting from the cosmic to the cellular, scientists at UC Davis have uncovered a fascinating genetic quirk that might explain why humans are more prone to certain cancers than our primate cousins. They've discovered a small genetic difference that affects a protein used by immune cells to kill tumors. In humans, this protein is vulnerable to being shut down by an enzyme that tumors release. Ironically, this same mutation might have helped our brains grow larger over evolutionary time. Researchers are now exploring ways to block this enzyme and restore our immune system's full power.

Here's something that might surprise you about marine life. A new study has overturned a 50-year assumption about how fish save energy while swimming in schools. Scientists long believed that fish swimming in tightly organized diamond formations could conserve the most energy. But researchers from Princeton and Harvard, using advanced 3D tracking technology, have found that the reality is quite different from what we've assumed for half a century.

On a lighter note, researchers have investigated something many of us might relate to: the connection between late-night cheese consumption and nightmares. In a survey of over 1,000 students, scientists found that people who consumed dairy products like cheese before bed were more likely to experience unsettling dreams, possibly due to gut discomfort disrupting sleep. So perhaps think twice before that midnight cheese snack.

In medical news, researchers have made a breakthrough in understanding organ rejection by capturing live images of how human immune cells invade and begin rejecting transplanted pig kidneys. This cellular warfare starts as early as day 10 and peaks at day 33, revealing a critical intervention window that could improve future xenotransplantation efforts.

Finally, surgeons at the University of Maryland Medical Center have achieved a world-first by removing a rare malignant spinal tumor through a patient's eye socket. This groundbreaking procedure on a 19-year-old woman preserved major nerves, blood vessels, and other critical structures in a hard-to-access area, opening new possibilities for treating complex tumors.

That's all for today's Science News Daily. From stellar mysteries to cellular battles, from cosmic explosions to innovative surgeries, science continues to amaze and challenge our understanding of the world around us. Keep looking up, keep questioning, and we'll see you next time with more discoveries from the frontiers of human knowledge.
