Mice taught to link smells with tastes, and later fear, revealed how the amygdala teams up with cortical regions to let the brain draw powerful indirect connections. Disabling this circuit erased the links, hinting that similar pathways in humans could underlie disorders like
Smarter people don’t just crunch numbers better—they actually see the future more clearly. Examining thousands of over-50s, Bath researchers found the brightest minds made life-expectancy forecasts more than twice as accurate as those with the lowest IQs. By tying cognitive
Researchers from Sweden have discovered that the human brain continues to grow new cells in the memory region—called the hippocampus—even into old age. Using advanced tools to examine brain samples from people of all ages, the team identified the early-stage cells that
Since 1970, 73% of global wildlife has been lost, while the world's population has doubled to 8 billion. Research shows this isn't a coincidence but that population growth is causing a catastrophic decline in biodiversity.
Understanding randomness is crucial in many fields. From computer science and engineering to cryptography and weather forecasting, studying and interpreting randomness helps us simulate real-world phenomena, design algorithms and predict outcomes in uncertain situations.
