3D images provide important knowledge about brain health

The brain is involved in everything in our body. When so-called neurodegenerative diseases such as Alzheimer's, ALS and multiple sclerosis attack the brain, they gradually degrade the human ability to concentrate, speak, remember and move. Despite extensive research, there is much that we still do not know about the brain. […]

Study Finds Alligator Hearts Keep Beating No Matter What

Mammals and cold-blooded alligators share a common four-chamber heart structure – unique among reptiles – but that’s where the similarities end. Unlike humans and other mammals, whose hearts can fibrillate under stress, alligators have built-in antiarrhythmic protection. The findings from new research were reported in the journal Integrative Organismal Biology. […]
