Welcome to Science News Daily. I'm your host, bringing you the latest breakthroughs and discoveries from the world of science. Today, we have some fascinating stories that span from the secrets of aging to remarkable creatures breaking biological records. Let's dive in.

First up, a heartwarming discovery about the power of human connection. New research suggests that strong social bonds may literally slow aging at the cellular level. Scientists have found that sustained social connections throughout life can lower inflammation and keep our body's "epigenetic clock" running younger. From parental warmth in childhood to friendships, community engagement, and even religious involvement in adulthood, these social advantages appear to offer genuine anti-aging benefits. It's remarkable to think that something as fundamental as human connection could have such profound effects on our biological processes.

Speaking of aging, there's exciting news from the world of nutrition. Researchers have discovered that cocoa supplements show surprising anti-aging potential. Daily cocoa extract supplements reduced key inflammation markers in older adults, pointing to a protective role for heart health. This finding reinforces the value of flavanol-rich, plant-based foods for healthier aging. So that daily square of dark chocolate might be doing more good than you think.

Now, let's venture into some truly cutting-edge research. In a world-first achievement, scientists have directly observed elusive particles called "dark excitons" using advanced spectroscopy systems. This breakthrough paves the way for studies in next-generation quantum information technologies. These discoveries are helping us understand the fundamental building blocks of matter in ways we've never seen before.

From the microscopic to the innovative, engineers have created soft robots that can literally walk on water. Using a novel technique called HydroSpread, scientists are building miniature robots no larger than a leaf that glide across water surfaces like water striders. These tiny machines could revolutionize environmental monitoring, healthcare applications, and robotics in general.

But perhaps one of the most intriguing stories comes from the natural world. Scientists have identified a mysterious creature with the most chromosomes on Earth. The Atlas blue butterfly carries a record-breaking 229 pairs of chromosomes, far more than any other known multicellular animal. This discovery is helping researchers unravel mysteries of evolution, adaptation, and even human cancer research.

Meanwhile, beneath the Arctic's frozen surface, tiny algae are defying the rules of biology. These resilient organisms are redefining the limits of life itself, raising urgent questions about ecosystems that may disappear with the melting Arctic ice.

In medical news, researchers have uncovered hidden Alzheimer's warning signs in Parkinson's patients who don't show dementia symptoms. Japanese scientists discovered that Parkinson's patients diagnosed in their 80s are three times more likely to show amyloid buildup, a hallmark of Alzheimer's disease. Surprisingly, Parkinson's patients overall showed lower amyloid buildup than healthy people their age, suggesting these conditions may interact in unexpected ways.

There's also promising news for stroke prevention. A natural compound called DMT, which occurs naturally in various plants and animals, shows promise in protecting the brain against stroke by safeguarding the blood-brain barrier and reducing inflammation.

Finally, here's a discovery that challenges our understanding of human evolution. New research suggests that autism may be the price of human intelligence. Scientists found that autism's prevalence may be linked to rapid evolution in specific brain neurons, with autism-linked genes changing under natural selection. These shifts may have slowed brain development in children while boosting language and cognitive abilities, suggesting autism could be part of the evolutionary trade-off that made humans so cognitively advanced.

That's all for today's Science News Daily. From social bonds slowing aging to robots walking on water, science continues to surprise and inspire us. Keep questioning, keep wondering, and we'll see you next time with more incredible discoveries from the world of science.
