Can Head Trauma Cause Alzheimer's?
Dr Arancio is a cellular neurobiologist who has contributed to the characterization of the mechanisms of learning in both normal conditions and during neurodegenerative diseases. During the past decade he has pioneered the field of mechanisms of synaptic dysfunction in Alzheimer’s disease. Dr. Arancio’s laboratory has focused primarily on events triggered by amyloid protein. These studies, which have suggested new links between synaptic dysfunction and amyloid protein, are of a general relevance to the field of Alzheimer’s disease both for understanding the etiopathogenesis of the disease and for developing therapies aiming to improve the cognitive symptoms.
One of the most robust environmental risk factors identified for Alzheimer’s disease is traumatic brain injury. This is having repercussions for those returning from fighting in Iraq and Afghanistan.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
Here's the first evidence to challenge the "fastest sperm" narrative.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
