Welcome to Science News Daily, where we explore the latest discoveries shaping our understanding of the world. I'm your host, bringing you today's most fascinating scientific breakthroughs.

Let's start with some groundbreaking health news that could affect millions of people. If you've heard about semaglutide, the popular weight-loss medication also known by brand names like Ozempic and Wegovy, there's important new research you should know about. Scientists have discovered that women and older adults using this medication may face a heightened risk of muscle loss. However, there's a simple solution that could help protect you - eating more protein. This finding is particularly significant given semaglutide's widespread use for obesity treatment. The researchers suggest that by increasing protein intake, users can potentially counteract this unwanted side effect while still benefiting from the medication's weight-loss properties.

Staying with health research, scientists have made a remarkable discovery about obesity prediction. Using genetic data from over five million people, researchers have developed a polygenic risk score that can predict whether someone is likely to develop obesity years before symptoms emerge. What's truly striking is that this genetic signature often appears before age five. This could revolutionize how we approach obesity prevention, allowing for early interventions based on genetic predisposition rather than waiting for weight gain to occur.

Now for some encouraging news for expectant mothers. A new UK study has shown that a single RSV vaccine shot during pregnancy can provide powerful protection for newborns. Babies whose mothers received the vaccine were 72% less likely to be hospitalized with severe RSV infections. This is huge news, as RSV is one of the most common and dangerous viruses for infants, often leading to serious respiratory complications.

Moving to infectious disease research, scientists are making progress against HTLV-1, a deadly virus that many people haven't heard of but affects millions worldwide. Researchers have discovered that HIV antivirals might be the key to stopping this virus, which currently has no cure. In a decade-long study using mice, they successfully suppressed the virus and found a way to kill infected cells, offering hope for both preventative and curative treatments.

Let's venture into space science now. NASA is funding a fascinating 621,000 dollar mission to search for alien chemistry right here on Earth. University of Massachusetts microbiologist James Holden is bringing his expertise in rare microbes to prepare for a mission to Europa, Jupiter's icy moon. The idea is that by studying extreme life forms on Earth, we can better understand what we might find in the subsurface oceans of Europa.

Speaking of aliens, here's something that might surprise you. New research suggests that Earth may be unintentionally broadcasting its location to potential alien civilizations. Radar systems from airports and military facilities are leaking electromagnetic signals into space that could be detected by technologically advanced extraterrestrial life. It's an accidental cosmic calling card that we've been sending without even realizing it.

Astronomers have also made a stunning discovery - a galaxy shaped like an infinity symbol. This bizarre structure, dubbed the Infinity galaxy, is actually two galaxies that recently collided. What makes it even more remarkable is that it may contain the first directly observed newborn supermassive black hole, giving us unprecedented insight into how these cosmic giants form.

In materials science, artificial intelligence is revolutionizing how we design new materials. Scientists at USC have created an AI model called Allegro-FM that can simulate billions of atoms at once. This breakthrough is helping them design futuristic materials like carbon-neutral concrete that could not only survive extreme weather and wildfires but actually heal itself and absorb carbon from the air. Imagine cities built with materials that actively fight climate change while lasting for centuries.

Paleontology fans, here's something exciting. A tiny dinosaur wrist bone discovery could completely rewrite our understanding of how flight evolved. Researchers analyzing theropod dinosaur fossils found that these ancient creatures possessed a type of wrist bone previously thought to be essential only for flight in birds. This suggests that the anatomical foundations for flight evolved much earlier than we previously believed.

In a delightful museum discovery, a 220-million-year-old sea dragon has been hiding in plain sight for decades. Researchers confirmed that a fossil in a Japanese museum is actually the first ichthyosaur ever found in western Japan, embedded in Late Triassic rock. It's a reminder that sometimes the most significant discoveries are sitting right under our noses in museum collections.

Here's something that might challenge what you believe about your canine companions. Despite our strong belief that dogs can sense good from bad in people, new research suggests they may not actually judge human character the way we think they do. When dogs watched humans treat other dogs poorly, they didn't favor the kinder person later. It turns out our four-legged friends might not be the moral judges we imagined them to be.

Astronomers have achieved something truly extraordinary - they've likely witnessed a planet forming in real time, 440 light-years from Earth. This direct observation of planetary formation, seen within a spiral arm of a protoplanetary disk, confirms theoretical predictions about how worlds are born.

In neuroscience, researchers have discovered something fascinating about optimism. Brain scans reveal that when imagining the future, optimists' brains tend to look remarkably similar to each other, while pessimists show more varied neural activity. This neurological alignment could explain why optimists often seem more socially synchronized with others.

Taking us back in time, scientists have successfully decoded the genome of the 1918 flu virus from a century-old preserved specimen. This Swiss sample reveals early adaptations that allowed the virus to infect humans, providing crucial insights into pandemic evolution that could help us prepare for future outbreaks.

Here's a simple health tip that could benefit millions. Eating pistachios every night for 12 weeks has been shown to positively change gut bacteria composition. This is particularly relevant for the roughly one-third of Americans affected by prediabetes, as improved gut health could help prevent progression to Type 2 diabetes.

In autism research, scientists from Princeton University and the Simons Foundation have identified four biologically distinct autism subtypes, each with unique genetic and developmental patterns. This breakthrough could lead to more personalized approaches to diagnosis and treatment, moving away from the one-size-fits-all model.

Finally, researchers have discovered a remarkable compound from deep-sea bacteria that can destroy cancer cells through what they describe as a fiery form of cell death. This natural sugar compound not only stops tumor growth in laboratory tests and mouse models but also activates the immune system to fight back. It could pave the way for entirely new cancer treatments based on marine organisms.

That wraps up today's Science News Daily. From protein protection against medication side effects to alien chemistry searches and cancer-fighting sugars from the deep sea, science continues to amaze us with discoveries that could transform our lives. Keep questioning, keep exploring, and we'll see you tomorrow with more fascinating science news. Until then, stay curious.
