Welcome to Science News Daily, your daily dose of fascinating discoveries from the world of science.

Today's headlines bring us remarkable breakthroughs in technology, health, and our understanding of the natural world.

In a groundbreaking development, engineers at the University of Pennsylvania have created the first-ever programmable chip that can train neural networks using light instead of electricity. This revolutionary breakthrough could dramatically speed up AI training while significantly reducing energy consumption, potentially paving the way for fully light-powered computing systems.

Speaking of quantum leaps, scientists have finally cracked a 20-year-old puzzle in quantum computing. They've derived an exact mathematical expression that could help purify quantum entanglement, a crucial step for advancing quantum computing and communication technologies.

In health news, there's promising progress in the fight against Alzheimer's disease. Researchers at the University of New Mexico Health Sciences are preparing to begin human trials for a new vaccine targeting tau proteins in the brain. This development represents a significant step forward in potentially preventing Alzheimer's disease.

A concerning study from the University of Toronto has revealed alarming levels of dangerous chemicals in baby mattresses. Researchers found that infants may be exposed to harmful substances like phthalates and flame retardants through inhalation or skin contact while sleeping.

On a lighter note, if you're a smoothie enthusiast, you might want to rethink adding bananas to your berry blend. New research indicates that bananas could significantly reduce the health benefits of flavanol-rich berries in your smoothie.

In evolutionary biology, researchers have made a fascinating discovery about crocodiles' survival through mass extinctions. Unlike their dinosaur contemporaries, these ancient creatures developed unique adaptations that allowed them to survive what their prehistoric neighbors couldn't.

And in a quirky bit of scientific innovation, researchers have successfully used nanotechnology to 'tattoo' tardigrades - those incredibly resilient microscopic creatures often called water bears. This breakthrough could lead to exciting developments in biocompatible microelectronics and medical technologies.

That's all for today's science news. Join us tomorrow for more amazing discoveries and breakthroughs reshaping our understanding of the world.
