Welcome to Science News Daily, where we explore the fascinating discoveries shaping our understanding of the universe. I'm your host, and today we have an incredible lineup of breakthroughs that span from the edge of space to the quantum realm, and even to surprising discoveries about our feline companions.

Let's start with some exciting news from NASA's Artemis program. Engineers have successfully test-fired the RS-25 engine at an impressive 111 percent power, generating a whopping 2 million pounds of thrust. This marks the first full-duration test of the new-build engines that will power the Space Launch System and send the Orion spacecraft toward the Moon. The engine roared for the full 500-second launch profile, proving it's ready to blast humanity back to our celestial neighbor.

Speaking of space, astronomers have made what they're calling a cosmic horror discovery. Using the Hubble Space Telescope, they've spotted a wandering supermassive black hole nicknamed "Space Jaws" that's literally devouring a star 600 million light-years away. What makes this discovery particularly remarkable is that it's the first optical detection of a roaming black hole caught in the act of shredding stellar material. This invisible giant is located off-center from its galaxy, making it a rare find that reveals new insights into how black holes behave in the cosmos.

In another astronomical breakthrough, scientists have solved a long-standing cosmic mystery by discovering the universe's "missing" matter. Using fast radio bursts as cosmic lighthouses, astronomers have mapped how ordinary matter is distributed in the vast spaces between galaxies. They've also detected the most distant fast radio bursts ever observed, giving us unprecedented insights into the structure of our universe.

Now let's dive into some revolutionary technology. Engineers at UBC have developed what they're calling a "universal translator" for quantum computers. This silicon-based device can convert microwave signals to optical signals and back again, potentially forming the foundation for a global quantum internet. Imagine quantum computers around the world being able to communicate seamlessly across vast distances.

Quantum computing got another boost from Swedish researchers who've created a new amplifier that uses 90 percent less power without sacrificing performance. This breakthrough could literally keep quantum computers cooler while maintaining their incredible processing speed, bringing us closer to practical quantum applications.

In a fascinating development for random number generation, NIST has built the first random-number generator powered by quantum entanglement. Their CURBy beacon transforms quantum "spooky action" into certified random numbers that are completely unpredictable, with applications ranging from jury selection to advanced cryptography.

Environmentally conscious tech lovers will be excited about a breakthrough from Flinders University, where scientists have developed a cleaner way to extract gold from electronic waste. Using compounds normally found in pool disinfectants and reusable polymers, this method avoids toxic chemicals like mercury and cyanide while recovering valuable metals from our mounting piles of e-waste.

Moving to sensing technology, researchers at EPFL have created a quantum-enabled biosensor that can detect a single trillionth of a gram of molecules using just electricity and a chip smaller than your fingernail. This self-illuminating sensor uses quantum tunneling effects to generate and detect light simultaneously, making it incredibly compact and ultra-sensitive.

In a surprising health discovery, Japanese scientists have found that vitamin C doesn't just brighten skin, it actually reactivates key growth genes that help create thicker, younger-looking skin. They traced this effect to specific enzymes that vitamin C energizes to unlock cell-growth genes, offering new insights into how this common vitamin affects aging.

For those interested in longevity, researchers from the University of East Anglia and Glasgow have found that the drug Rapamycin may extend lifespan as effectively as calorie restriction, one of the most proven anti-aging interventions. Even more intriguingly, scientists have discovered that caffeine activates an ancient cellular switch called AMPK that helps cells manage stress and repair damage, potentially contributing to slower aging.

Now for a delightful discovery about our feline friends: researchers have found that cats overwhelmingly prefer sleeping on their left side. This isn't just a quirky preference, it might actually be an evolutionary survival strategy. Sleeping on the left side activates the brain's right hemisphere upon waking, which is perfect for detecting danger and reacting swiftly.

Finally, in evolutionary news, scientists studying over a century of rodent specimens from Chicago have discovered that urban wildlife is evolving right under our noses. Subtle but significant changes in chipmunk and vole skulls show these animals are adapting to city life in real time.

That wraps up today's tour through the latest scientific discoveries. From quantum computers to cosmic black holes, from anti-aging breakthroughs to evolving urban wildlife, science continues to surprise and inspire us every day. Thanks for joining us on Science News Daily, and we'll see you next time for more fascinating discoveries from the world of science.
