Welcome to Science News Daily, where we bring you the latest discoveries from the world of science. I'm your host, and today we're diving into some fascinating research that's reshaping our understanding of everything from animal behavior to quantum computing.

Let's start with a heartwarming story from the forests of Gombe that reveals something remarkable about friendship in the animal kingdom. A decades-long study of chimpanzees has uncovered that female chimps who build strong friendships with unrelated females dramatically improve their babies' chances of survival. The researchers found that social bonding before birth, especially through grooming and companionship, offers powerful protection against infant mortality in the wild. What's particularly interesting is that these life-saving bonds aren't formed with family members, but with completely unrelated females. It's a beautiful example of how friendship can be just as important as family ties in the animal world.

Speaking of surprising animal behavior, killer whales are doing something that has scientists scratching their heads. Across oceans and decades, orcas have been caught offering food to humans. From California to New Zealand, 34 documented incidents reveal these intelligent marine mammals bringing fish, rays, and squid to people in the water, on boats, and even onshore. This behavior is usually seen between whales as a bonding act, which raises fascinating questions about how these creatures perceive their relationship with humans.

Now, here's something that might explain your cat's sleeping habits. Scientists have discovered why cats often sleep on their left side, and it's all about survival. An international team of researchers analyzed hundreds of YouTube videos featuring cats in side-sleeping positions and found that cats appear to favor resting on their left side because their brain processes danger more efficiently this way. It allows them to spot threats faster, showing that even in sleep, our feline friends are thinking about safety.

Moving into the realm of atomic science, researchers at ETH Zurich have achieved something truly remarkable. They've developed a powerful method to look deep inside single-atom catalysts, materials where every atom plays a vital role in driving chemical reactions. Using nuclear magnetic resonance technology, similar to MRI scans, they've uncovered how platinum atoms interact with their surroundings on an atomic level. This breakthrough could revolutionize how we design catalysts for everything from clean energy to manufacturing.

In quantum computing news, scientists have just simulated what was previously considered impossible. One of the major challenges in quantum computing is correcting errors during calculations, and to build reliable quantum machines, scientists need to simulate these quantum processes on regular computers. This is one of the most complex tasks in computing, but researchers have made significant progress in tackling this challenge, bringing us closer to truly reliable quantum computers.

Here's a fascinating connection between past and present in physics. A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics experiment from 1938 - the first recorded observation of deuterium-tritium fusion. Their updated version of this forgotten experiment is now connecting past theory with current fusion efforts, potentially helping power the future of clean energy.

On the health front, there's encouraging news about Alzheimer's prevention. A study from the University of Hawaii Cancer Center found that people who followed the MIND diet were much less likely to develop Alzheimer's disease or other types of dementia, even if they adopted healthier eating habits later in life. This suggests that it's never too late to start eating better for your brain health.

Medical research has also yielded promising results in cancer treatment. Scientists have developed a new cancer drug candidate that can inhibit tumor growth without the debilitating side effects typically associated with cancer treatments. This breakthrough was achieved through a collaboration using high-performance computing and artificial intelligence, targeting specific pathways without causing harmful side effects.

However, there's also concerning news about environmental health. A sweeping study funded by the National Institutes of Health tested the urine of 200 toddlers and found a startling mix of 96 chemicals, some of which aren't even tracked by government health surveys. These toxins, from plastics, flame retardants, and pesticides, were found in 90% of the children tested, showing up through everyday exposures like food, air, and playtime.

Let's journey to Mars for a moment, where NASA's Curiosity rover has captured something spectacular. The rover stitched together 291 photos into a stunning 360-degree panorama of Gale Crater's boxwork ridges - spiderweb-like stone lattices that were hardened by ancient groundwater. These striking patterns reveal how minerals cemented cracks billions of years ago, giving us insight into Mars' watery past.

For those who love to look up at the night sky, July offers quite a show. Mars glows at dusk while Mercury makes a brief appearance, Venus blazes before dawn, and Jupiter joins it for a photogenic pairing. Saturn lingers past midnight, and the Moon stages close encounters with Mars and the morning planets. It's a perfect time to celebrate sixty years since Mariner 4's historic flyby of Mars.

Finally, let's venture into one of the most mysterious aspects of our universe. Scientists believe that strange types of stars called dark dwarfs may be quietly glowing in the center of our galaxy, not from fusion like our Sun, but from dark matter itself. These cosmic objects could act like detectors, collecting heavy, elusive particles that heat them from the inside. If we find them, they could help us finally understand the true identity of dark matter.

That's all for today's Science News Daily. From the social bonds of chimpanzees to the mysteries of dark matter, science continues to surprise and inspire us. Keep looking up, stay curious, and we'll see you next time for more fascinating discoveries from the world of science.
