A little night cap video …

I just thought you should know about this: Researchers Create Robot Driven by Moth’s Brain from PhysOrg.com In a notion taken from science fiction afficionados, University of Arizona researchers presented a robot that moves by using the brain impulses of a moth at the 37th annual Society for Neuroscience meeting in San Diego.

Evolution Directed, Not Random…

Well, this is interesting: Evolution is deterministic, not random, biologists conclude from multi-species study from PhysOrg.com A multi-national team of biologists has concluded that developmental evolution is deterministic and orderly, rather than random, based on a study of different species of roundworms. The findings are reported in the latest issue of the journal Current Biology.…

Fish Oil, Statins, and Neural Disease

The “statins” make up a class of cholesterol lowering drugs. Fish oil (oil derived from fish) is rich in certain fatty acids. Both types of compounds can have powerful positive and protective effects in the brain. A study just now coming out (to be published in Brain Research Reviews) looks at the biochemical effects of…
