Welcome to Science News Daily, where we explore the fascinating discoveries shaping our understanding of the world around us. I'm your host, bringing you the latest breakthroughs from the frontiers of scientific research.

Let's start with a remarkable journey through time. Scientists have unearthed the oldest true cicada ever found in Europe, dating back an astounding 47 million years. This fossilized specimen, dubbed Eoplatypleura messelensis, was discovered in Germany's famous Messel Pit deposits. What makes this discovery particularly exciting is that it represents the earliest known record of the subfamily Cicadinae worldwide, giving us unprecedented insight into how these iconic insects evolved across Eurasia millions of years ago.

Speaking of ancient tales, researchers have pieced together an epic 500-million-year story of ocean survival by studying fossil shells. By analyzing over 7,700 limestone samples, Stanford scientists discovered that marine biomass and biodiversity have risen hand-in-hand throughout Earth's history, only declining during major extinction events. The findings reveal that more diverse seas are better at recycling nutrients and building robust food webs - a pattern that's now threatened by human-driven species loss.

Deep beneath Ethiopia, scientists have detected something extraordinary - Earth's geological pulse. In the Afar Rift, rhythmic surges of molten mantle rock are literally tearing the African continent apart. These powerful geologic heartbeats are thinning Earth's crust and may eventually create a new ocean. By studying chemical signatures in volcanic rocks, researchers can now track these waves of molten material as they rise through the mantle, guided by shifting tectonic plates.

In the realm of quantum technology, researchers have achieved a remarkable milestone by building an 11-mile-long quantum highway. The Rochester Quantum Network connects university campuses using fiber-optic lines that transmit information via single photons. This experimental network represents a significant step toward practical quantum communications, potentially revolutionizing how we share secure information across long distances.

Medical researchers are making promising discoveries about natural compounds from mushrooms. A phase 2 clinical trial has shown that a single dose of psilocybin, the psychedelic compound found in certain mushrooms, can provide lasting relief from depression and anxiety in cancer patients. This breakthrough suggests that psychedelic medicines might offer new hope for people battling both physical illness and mental health challenges.

We're also learning more about why exercise keeps us young. Scientists have identified a key protein called CLCF1 that declines with age but is released during physical activity. This protein, known as a myokine, appears to help protect against musculoskeletal aging, finally providing a molecular explanation for exercise's anti-aging effects.

However, not all health news is positive. A landmark study has found that cannabis use doubles the risk of dying from cardiovascular disease and significantly increases the risk of stroke and heart problems. The research suggests we should treat cannabis similarly to tobacco - avoiding criminalization while discouraging use and protecting bystanders from potential harm.

Looking to the stars, NASA is preparing to test high-speed laser communications on the upcoming Artemis II mission. Working with Australia's National University, they're developing budget-friendly technology that could beam 4K video from the Moon back to Earth at record speeds. If successful, this could revolutionize how future lunar crews communicate with mission control.

Mars continues to surprise us with Earth-like features. Scientists have discovered mysterious wave-like patterns in Martian soil that provide new clues about the red planet's icy history and its potential to support life. These landforms suggest Mars and Earth may share more similarities than previously thought.

Finally, the James Webb Space Telescope has achieved another first - capturing the first direct image of an alien planet carving cosmic rings around its star. The newly discovered world, called TWA 7 b, is about the mass of Saturn and represents Webb's first direct image discovery of an exoplanet, adding to the nearly 6,000 worlds we've found beyond our solar system.

That's all for today's Science News Daily. From ancient cicadas to alien worlds, from quantum highways to Earth's geological heartbeat, science continues to reveal the incredible complexity and beauty of our universe. Keep exploring, keep questioning, and we'll see you tomorrow with more fascinating discoveries from the world of science.
