Welcome to Science News Daily, where we explore the latest discoveries shaping our understanding of the world. Today, we're covering fascinating research from tiny worms that reveal secrets about aging, to ancient civilizations, breakthrough technologies, and urgent health findings that could impact millions of lives.

Let's start with some surprising news from the world of aging research. Scientists studying starved worms have uncovered what they're calling a hidden switch for cellular aging. When researchers altered the activity of a transcription factor called TFEB in these worms, they triggered a senescent-like state that mirrors mammalian aging processes. This discovery is particularly exciting because worms offer a simple yet powerful model for studying age-related diseases and could even help develop dormant cancer therapies. The fact that these tiny creatures can teach us so much about human aging never ceases to amaze.

Speaking of health concerns, let's turn to some troubling findings about teen vaping. A large national study reveals that between 2021 and 2023, more adolescents reported vaping not just nicotine, but a dangerous mix of THC, CBD, and synthetic drugs. Perhaps most alarming is that many teens don't even know what they're inhaling. This shift from traditional nicotine vaping to unregulated substances represents a significant public health challenge that parents, educators, and policymakers need to address urgently.

Now, here's a study that might make you think twice about your lunch choices. A comprehensive 23-year follow-up of more than half a million Americans has revealed that those who consume large amounts of ultra-processed foods face about a 10 percent higher risk of dying, especially from heart disease and diabetes. We're talking about foods like sugary sodas, deli meats, and hot dogs. What makes this study particularly compelling is that the increased risk remained even when researchers accounted for weight, smoking habits, and overall diet quality, suggesting there's something specifically harmful about ultra-processed foods themselves.

Let's journey back in time now to ancient Anatolia, where DNA analysis is revealing fascinating insights about one of humanity's earliest organized settlements. At Çatalhöyük, a major Neolithic settlement that thrived 8,000 to 9,000 years ago, genetic studies point to female-centered living arrangements. This suggests a potentially matriarchal society, though researchers caution that power structures may have been more complex than a simple female-dominated hierarchy. It's remarkable how modern genetic techniques can illuminate the social structures of our ancient ancestors.

Staying with archaeology, researchers have unearthed a lost temple of the Tiwanaku civilization along the southern edge of Lake Titicaca in Bolivia. This discovery shows how the Tiwanaku connected sacred rituals with Andean trade and political networks. As one of the earliest organized cultures in the Andes and a forerunner to the Inca Empire, these findings help us understand how ancient civilizations built complex societies in challenging environments.

From ancient temples to cutting-edge technology, researchers from The University of Manchester and The Australian National University have developed a remarkable molecule capable of storing data at extremely low temperatures comparable to the dark side of the moon. This breakthrough could enable tiny hard drives that store vastly more data than current technology allows, paving the way for dense and efficient storage solutions that could revolutionize computing.

In environmental news, Korean scientists have achieved a breakthrough in carbon dioxide conversion, transforming this greenhouse gas into valuable chemical fuels with record-setting efficiency. As carbon emissions continue to hit record highs and the urgency for carbon neutrality grows, this technology offers hope for turning a climate problem into a valuable resource.

Meanwhile, physicists are closing in on what could be a fifth fundamental force of nature using trapped ions in cutting-edge experiments. They're hunting for signs of an undiscovered particle that might help unravel the mystery of dark matter. If confirmed, this could fundamentally change our understanding of the universe beyond the Standard Model of particle physics.

Let's talk about some health discoveries that could affect your daily life. Scientists have discovered how brown fat, your body's hidden weight loss engine, operates like a natural furnace to keep you warm and lean. When temperatures drop, a protein that normally blocks fat burning gets switched off, allowing these special fat cells to burn calories and produce heat. This discovery could lead to new approaches for weight management and metabolic health.

Speaking of health, researchers have developed a multi-strain probiotic blend that shows promise for protecting brain function by reducing gut-triggered inflammation linked to Alzheimer's disease. This gut-boosting drink could offer meaningful benefits for brain health, especially as our global population continues to age.

And here's some sobering news about our planet's forests. Tropical trees are dying faster than ever, and scientists have uncovered a surprising culprit: ordinary thunderstorms. These quick, fierce storms, powered by climate change, are toppling trees with intense winds and lightning, sometimes causing more damage than drought itself. Researchers warn that storms may be responsible for up to 60 percent of tree deaths in some regions, and failing to account for this hidden force could undermine forest conservation and climate models.

Finally, research into Earth's greatest extinction event, the Great Dying, reveals that when Siberian volcanoes kicked off this catastrophe, the real climate villain turned out to be the rainforests themselves. Once they collapsed, Earth's biggest carbon sponge vanished, carbon dioxide levels rocketed, and a five-million-year heatwave followed. This finding hints that losing today's tropical forests could lock us in a furnace we can't easily cool.

That's all for today's Science News Daily. From microscopic worms revealing aging secrets to ancient civilizations and cutting-edge technologies, science continues to surprise and inform us. Join us tomorrow for more discoveries that are shaping our understanding of the world around us.
