Studies of food’s impact on Alzheimer’s disease and dementia are hampered by complexity. Scientists hope new research approaches prove more fruitful.
- Paleontology
Feathers may have helped dinosaurs survive the Triassic mass extinction
New data show that dinosaurs were able to weather freezing conditions about 202 million years ago, probably thanks to warm feathery coats.
- Paleontology
Megatooth sharks may have been higher on the food chain than any ocean animal ever
