Welcome to Science News Daily. I'm your host, bringing you the most exciting discoveries from the world of science. Today, we're diving into some remarkable breakthroughs that could change how we think about cancer treatment, brain health, and even the materials around us.

Let's start with a sweet discovery that's anything but ordinary. Scientists have found that fermenting stevia, the popular sugar substitute, with a probiotic derived from banana leaves transforms it into a powerful cancer-fighting agent. This process creates a metabolite called CAME that specifically targets pancreatic cancer cells while leaving healthy cells unharmed. It's fascinating how a simple fermentation process can turn something we use to sweeten our coffee into a potential lifesaver.

Speaking of unexpected benefits, researchers have uncovered another surprising health advantage of GLP-1 drugs like Ozempic. Beyond their well-known effects on diabetes and weight loss, new studies presented at the Society of NeuroInterventional Surgery meeting suggest these medications may reduce stroke risk and improve recovery from brain damage. This discovery opens up exciting possibilities for protecting our most vital organ.

In the realm of materials science, physicists at the University of Konstanz have achieved what was once thought impossible. They've successfully rewritten a material's magnetic properties using nothing but light and magnons, without heat or chemicals. Imagine being able to temporarily transform one material into behaving like an entirely different one. It sounds like science fiction, but it's happening in laboratories today.

After decades of mystery, scientists have finally solved a puzzle in photosynthesis. Researchers from the Indian Institute of Science and Caltech discovered why plants only use one of two seemingly identical pathways in this crucial process. They found hidden energy barriers and structural differences that could help us engineer more efficient artificial photosynthesis systems.

Moving to conservation, drones are revolutionizing wildlife surveys in remarkable ways. University of Florida researchers used drone technology to discover the largest known nesting site for a threatened turtle species in the Amazon River, counting an astounding 41,000 rare turtles. This new counting method corrected major errors in traditional surveys and could transform how we monitor endangered species.

Artificial intelligence continues to enhance medical care in unexpected ways. Researchers have developed AI that can turn a routine, low-cost heart test into a powerful screening tool for hidden structural heart diseases. This could make early detection of valve defects and congenital abnormalities much more accessible.

Sometimes the simplest solutions are the most effective. A groundbreaking study followed over 700 participants for three years and found that walking nearly doubles the pain-free time for people recovering from lower back pain. Not only did walkers experience fewer recurrences, but they also needed less medical care over time.

Finally, researchers have discovered another way sugar compounds can fight cancer, this time from an unexpected source. A sugar found in deep-sea bacteria triggers a dramatic form of cell death called pyroptosis, making cancer cells literally explode from the inside out. Even better, this process signals the immune system to join the fight against remaining cancer cells.

That's all for today's Science News Daily. From sweet cancer fighters to exploding cells, from walking cures to magnetic transformations, science continues to surprise and inspire us. Keep exploring, keep questioning, and we'll see you tomorrow for more amazing discoveries from the world of science.
