An ancient viral infection may have given animals the tools to become fast, coordinated and smart, a study has found. According to a paper published Thursday in Cell, complex nervous systems arose in the distant past after viruses inserted bits of code into the genomes of vertebrates — animals with a spinal cord, from humans…
Ancient viruses that infected vertebrates hundreds of millions of years ago played a pivotal role in the evolution of our advanced brains and large bodies, a study said Thursday. This led them to believe the sequence appeared in the tree of life around the same time as jaws, which first evolved around 360 million years ago in the Devonian period, called the Age of Fishes.
A new treatment shows promise against the deadly neurodegenerative disease ALS, a study based on mice showed Tuesday. The team tested their molecule in mice that were genetically modified to have a form of ALS disease, and found it not only restored the protein's function, but stopped its secondary toxic effects too.
Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules, which could in future be developed into a stroke recovery therapy.
