Welcome to Science News Daily, where we explore the latest discoveries shaping our understanding of the world. I'm your host, bringing you the most fascinating science stories from this week.

Today we're taking a journey from the red planet to ancient Earth, from melting ice sheets to quantum computers, and from microscopic ants to mysterious galaxies.

Let's start with some incredible news from Mars. NASA's Perseverance rover has captured its clearest images yet of the Martian landscape, revealing stunning 360-degree panoramic views from a location called Falbreen. These images, stitched together from 96 separate photographs, show both enhanced-color and natural-color versions of the Martian terrain. What's particularly striking is how the enhanced version features deceptively blue skies, while the natural-color image reveals Mars' more familiar reddish atmosphere. The rover has also completed its 43rd rock abrasion of the mission, continuing its search for signs of ancient life.

Speaking of Mars exploration, our other Martian explorer, Curiosity, is getting smarter after 13 years on the red planet. The rover has learned to multitask, running more efficiently than ever as it explores fascinating boxwork formations on Mount Sharp. These geological features may hold crucial clues about ancient water activity and possibly even microbial life. It's remarkable how these aging robots continue to surprise us with their capabilities.

Closer to home, we have some unexpected news about climate change. While Greenland's melting ice sheet is raising sea levels, NASA researchers have discovered it's also supercharging ocean life. The glacial runoff near Jakobshavn Glacier is lifting nutrient-rich deep waters to the surface, fueling summer phytoplankton blooms by up to 40 percent. This shows us once again how interconnected Earth's systems really are.

In another water-related story, scientists are studying mysterious oases appearing on the drying shores of the Great Salt Lake. As water levels continue to drop, clusters of reed-covered mounds have emerged, marking locations where ancient groundwater emerges at the surface. These unusual features are giving researchers new opportunities to understand the lake's complex underground systems.

Now, let's talk about some fascinating animal behavior that could revolutionize robotics. Weaver ants have solved a teamwork puzzle that has stumped humans for over a century. Instead of becoming less efficient as their group grows larger, these tiny architects actually work harder when more ants join in. They use what researchers call a force ratchet system, where some ants pull while others anchor, allowing them to double their pulling power and outperform human teams. This discovery could inspire revolutionary advances in robotics cooperation.

Another ant study from Puerto Rico reveals the complex ecological dance between three ant species and a predator fly on coffee farms. This chaotic web of interactions shows how shifting dominance patterns make biological pest management incredibly unpredictable, highlighting both the potential and challenges of replacing pesticides with ecological methods.

Moving from the very small to the very large, the Hubble Space Telescope has spotted an almost invisible galaxy called NGC 45. This spiral galaxy belongs to the rare class of low surface brightness galaxies, which are actually dimmer than the night sky itself, yet they're rich in gas and dark matter. Its faint glowing pink star-forming clouds reveal hidden stellar nurseries in what appears to be empty space.

In the realm of fundamental physics, we have exciting developments on two fronts. The ATLAS collaboration at CERN has reported evidence for Higgs bosons decaying into muons, bringing us closer to understanding the particle that gives other particles their mass. Meanwhile, researchers are using Google's quantum processor to simulate fundamental physics, offering new ways to study the universe's basic forces and particles that are far beyond what traditional supercomputers can handle.

Space exploration continues to yield surprises. NASA's SWOT satellite captured rare, detailed measurements of a tsunami generated by an 8.8 magnitude earthquake near Russia's Kamchatka Peninsula. This data is helping NOAA improve its tsunami forecast models, which are crucial for early warnings to coastal communities. And in a discovery that's captured astronomical attention, the James Webb Space Telescope has detected strong evidence for a giant planet orbiting Alpha Centauri A, our nearest Sun-like star, just 4 light-years away.

Turning to ancient history, DNA analysis is rewriting the story of language families. New research reveals that the parent language of Hungarian and Finnish emerged over 4,000 years ago in Siberia, much farther east than previously thought, before rapidly spreading westward. This discovery comes from analyzing hundreds of ancient genomes and tracking genetic signals across millennia.

Another fascinating ancient discovery involves our human relatives. Scientists have used ancient proteins to solve a 2-million-year-old mystery about Paranthropus robustus, revealing that this species may have been more complex and varied than previously believed. And speaking of our ancestors, researchers have found that Neanderthal DNA still present in some Europeans might actually hinder athletic performance, potentially halving one's chances of becoming an elite athlete due to reduced muscle efficiency.

Multiple studies are showing how Denisovans, another mysterious human relative, left genetic fingerprints across the globe through interbreeding events. These genetic gifts helped shape traits like high-altitude survival in Tibetans, cold-weather adaptation in Inuits, and enhanced immunity in various populations.

Finally, we have some important health findings. A parasitic worm has been discovered that can shut down pain and itch signals in the skin during infection, which scientists hope could lead to better pain treatments. Research is also revealing that modern cannabis is five times stronger than it once was, with frequent use of high-THC varieties linked to increased risks of psychosis and schizophrenia, especially in young people. And in nutrition news, eating French fries just three times a week was linked to a 20 percent higher chance of developing type 2 diabetes, while other potato preparations showed no such association.

From ancient creatures in the Grand Canyon to cutting-edge quantum simulations, this week reminds us that science continues to surprise us at every scale, from the microscopic to the cosmic. Each discovery builds our understanding of the intricate, interconnected universe we call home.

That's all for today's Science News Daily. Keep looking up, keep asking questions, and we'll see you next time with more amazing discoveries from the world of science.
