Welcome to Science News Daily. I'm your host, bringing you the latest discoveries from the world of science.

Today we're diving into some fascinating findings that span millions of years of Earth's history and could reshape our future. Let's start with a prehistoric discovery that's filling in gaps in our understanding of ancient life.

For the first time ever, paleontologists have discovered a fossilized dragonfly wing from the Cretaceous period in Canada. Found in Alberta's famous Dinosaur Provincial Park, this ancient wing represents not just the earliest dragonfly fossil ever recovered from Canada's dinosaur-era rock layers, but also reveals a previously undocumented 30-million-year gap in dragonfly evolution. This tiny wing is helping scientists piece together how these aerial acrobats survived alongside the dinosaurs and evolved into the creatures we see today.

Speaking of evolution, new fossils from Ethiopia are completely reshaping our understanding of human ancestry. Recent discoveries reveal that our early ancestors weren't following a straight evolutionary path from ape to human. Instead, researchers have uncovered evidence of a complex, branching tree where multiple species coexisted. The most striking finding? Males of some early human ancestors, including Australopithecus afarensis, were dramatically larger than their female counterparts - much more like gorillas than modern humans. This extreme size difference suggests very different social behaviors than what we see in humans today.

But perhaps even more intriguing, newly discovered teeth from northeastern Ethiopia show that Australopithecus lived alongside some of the earliest Homo specimens nearly 2.8 million years ago. This suggests that nature was essentially testing multiple versions of being human before our particular lineage endured.

Now let's shift from ancient history to cutting-edge technology. Researchers at Caltech have achieved a major breakthrough in quantum computing by converting quantum information into sound waves. Using a device that acts like a miniature tuning fork, they've managed to extend quantum memory lifetimes up to 30 times longer than before. This could be the key to building practical, scalable quantum computers that can both compute and remember - solving one of the biggest challenges in quantum technology.

Moving into space, the James Webb Space Telescope has revealed something extraordinary hidden within the Butterfly Nebula. This cosmic cloud contains a complex mix of gemstone-like crystals, fiery dust, and unexpected carbon molecules. The discovery could rewrite how we understand the chemistry that seeds planets and life itself throughout the universe.

Here on Earth, scientists have made some remarkable discoveries about animal behavior. In Taiwan's forests, researchers found that sheet web spiders have developed a truly ingenious hunting strategy. Instead of immediately eating captured fireflies, these spiders allow them to continue glowing in their webs, essentially using them as living bait to attract even more prey. Experiments with LED lights confirmed this eerie strategy works - webs lit with firefly-like signals attracted up to ten times more insects.

On the conservation front, researchers studying whale sharks in Indonesia have found that the majority of these gentle giants are scarred by human activity. Fishing equipment and boats are the biggest threats, especially as shark tourism continues to grow. The good news? The solution might be as simple as redesigning fishing gear and boat equipment to be less harmful to these magnificent creatures.

In biotechnology news, scientists have discovered what they're calling plastivore caterpillars - waxworms that can devour polyethylene plastic bags in just 24 hours. These remarkable creatures actually metabolize plastic into body fat, offering a potential solution to our global plastic waste crisis. There's a catch though - on a plastic-only diet, the caterpillars weaken and die quickly, so researchers still have work to do.

Finally, let's look at some promising health discoveries. A major study has found that just three simple lifestyle changes can cut the risk of type 2 diabetes by 31 percent: adopting a Mediterranean-style diet while reducing daily calories, engaging in moderate physical activity, and receiving professional weight-loss support. And for those suffering from knee arthritis, a comprehensive analysis of over 100 clinical trials found that knee braces, water therapy, and regular exercise are the most effective non-drug treatments available.

That's all for today's Science News Daily. From ancient dragonflies to quantum computers, from glowing spider traps to plastic-eating caterpillars, science continues to surprise and inspire us. Keep exploring, keep questioning, and we'll see you next time for more discoveries that are shaping our understanding of the world around us.
