A new fMRI study finds that the outcome of freely made decisions is encoded in prefrontal and parietal cortices up to ten seconds before conscious awareness. Thus, these brain regions begin to prepare an upcoming choice before subjects are aware of it.
The brain is a part of the body that allows us to make sense of the world around us and to change our behavior to respond to it. In most animals, the brain is inside the head. The brain is kept safe by the skull and by layers of tissue under it called the meninges.
The human brain controls the central nervous system (CNS), by way of the cranial nerves and spinal cord, the peripheral nervous system (PNS) and regulates virtually all human activity.
A study has revealed that the brain makes decisions about 10 seconds prior to a person realizes it. Experts involved in the study said that looking at brain activity while making a decision, they could predict the choices the subjects would make, before they realized that they had made a decision.

Insect are the most diverse group of animals on the Earth, with over a million described speciesâ€” more than half of all known living organism. Insects may be found in nearly all environments on the planet, although only a small number of species occur in the oceans. Now there is a new theory that suggests that insect attack may have finished off dinosaurs. An important contributor to the demise of the dinosaurs, experts say, could have been the rise and evolution of insects, especially the slow-but-overwhelming threat posed by new disease carriers.
From the article:
Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new arguemet is that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force — biting, disease-carrying insects.
=> Insect Attack May Have Finished Off Dinosaurs
Dinosaurs were large size animals that dominated terrestrial ecosystems for over 160 million years, first appearing approximately 230 million years ago. Non-avian dinosaurs suddenly became extinct approximately 65 million years ago. Now a high school student hunting fossils in the badlands of his native North Dakota discovered an extremely rare mummified dinosaur that includes not just bones but also seldom seen fossilized soft tissue such as skin and muscles, scientists will announce today. With this new discovery it may be possible to create jurassicpark :)
This is a neat find. I can say a rare find, but I think it is not enough for any actual biotechnology to build jurassicpark.
