When a molecule of tryptophan absorbs ultraviolet light, it glows faintly as it lets off lower-frequency energy. This soft glow, known as fluorescence, is a familiar effect. But when many tryptophan ...

Here’s what you’ll learn when you read this story: For the past 30 years, scientists have investigated whether the human brain might require quantum processes to achieve cognition. A study from ...

An interdisciplinary team of researchers are working on a radically new kind of computer called a neuromorphic computer, inspired by the human brain. Mock-up of a quantum photonic device, which could ...

BUFFALO, N.Y. — It’s estimated it can take an AI model over 6,000 joules of energy to generate a single text response. By comparison, your brain needs just 20 joules every second to keep you alive and ...

The world’s most powerful supercomputers can now run simulations of billions of neurons, and researchers hope such models ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...
