Welcome to Science News Daily, where we explore the latest discoveries that are reshaping our understanding of the universe and ourselves. I'm your host, and today we've got some absolutely fascinating stories that span from the depths of space to the microscopic world within our bodies.

Let's start with a cosmic tale that sounds like science fiction. Astronomers have discovered a rogue planet that's literally feasting on space dust at an incredible rate of six billion tonnes per second. This runaway world represents the fastest planetary growth ever observed, and it's challenging our understanding of how planets form. What makes this discovery particularly intriguing is that this planet appears to be growing more like a star than a traditional planet, suggesting there might be alternative pathways for planetary formation that we're only just beginning to understand.

Speaking of cosmic mysteries, a groundbreaking new study is challenging one of the fundamental pillars of modern cosmology. Researchers are claiming that dark matter and dark energy, which we believe make up most of the universe, might not exist at all. Instead, they propose that these mysterious components could be illusions caused by the universe's forces gradually fading over time. If this theory holds up, it would completely revolutionize our understanding of the cosmos and force us to rewrite the textbooks on how the universe works.

But space isn't the only place where surprising discoveries are happening. Scientists at the University of Hawaii have finally solved a mystery that's been puzzling researchers for years: why it rains on the Sun. Unlike Earth's water droplets, solar rain consists of plasma falling back to the Sun's surface. The researchers discovered that changes in the Sun's elemental makeup drive these mysterious plasma downpours, giving us new insights into our star's complex behavior.

Moving from the cosmic scale to the human scale, we have some breakthrough medical news. Researchers in Japan have made significant progress in understanding long COVID's mysterious brain fog. Using advanced brain imaging techniques, they've identified specific biological changes in the brain that correspond to cognitive impairment and inflammation. This discovery confirms that brain fog is a measurable, biological condition rather than just a vague symptom, potentially opening the door to more effective treatments.

Another major breakthrough in neuroscience comes from Scripps Research, where scientists have discovered a brain circuit that traps people in the cycle of alcohol addiction. They found that a tiny brain region called the paraventricular nucleus of the thalamus becomes hyperactive when it learns that alcohol relieves withdrawal symptoms. This discovery helps explain why addiction recovery is so challenging and why relapses occur, as the brain literally learns that alcohol brings relief from stress and anxiety.

In cardiac research, scientists at Massachusetts General Hospital have identified a protein that literally punches holes in heart tissue after a heart attack. This protein, called RELMy, comes from immune cells and disrupts normal heart rhythm, potentially leading to life-threatening complications. The good news is that by understanding this mechanism, researchers may be able to develop new treatments to block this protein and improve survival rates.

On the technology front, Cambridge scientists have unlocked a century-old quantum secret that could revolutionize solar power. They've discovered a hidden quantum mechanism in organic semiconductors that was previously thought to exist only in inorganic materials. This finding connects modern research with theoretical work from a hundred years ago and could lead to more efficient solar energy conversion.

Perhaps one of the most impressive recent discoveries comes from the world of thermodynamics, where Japanese researchers have found a way to exceed traditional limits like the Carnot efficiency. Using quantum states that don't undergo thermalization, they've developed a method to convert waste heat into electricity more efficiently than ever thought possible, potentially revolutionizing how we harvest energy.

Finally, let's end with some discoveries that remind us of the incredible diversity of our planet's history. In Ecuador, researchers have found 112-million-year-old insects preserved in amber, offering a rare glimpse into ancient South American ecosystems. Meanwhile, in Arabia, colossal 12,000-year-old rock art is revealing forgotten human cultures that thrived in what was once a forbidding desert landscape.

These discoveries remind us that science continues to surprise us, whether we're looking deep into space, deep into the past, or deep into the mechanisms of life itself. Each breakthrough opens new questions and new possibilities, keeping the spirit of discovery alive and well.

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