Since its inception in the early 20th century, neuroscience has taught us a tremendous amount about the brain.
Our sensations have been reduced to a set of specific circuits. The mind has been imaged as it thinks about itself, with every thought traced back to its cortical source. The most ineffable of emotions have been translated into the terms of chemistry, so that the feeling of love is just a little too much dopamine. Fear is an excited amygdala. Even our sense of consciousness is explained away with references to some obscure property of the frontal cortex. It turns out that there is nothing inherently mysterious about those 3 pounds of wrinkled flesh inside the skull. There is no ghost in the machine.
New research from the University of Bristol shows that by suppressing one of the genes that normally switches on in wound cells, wounds can heal faster and reduce scarring. This has major implications not just for wound victims but also for people who suffer organ tissue damage through illness or abdominal surgery.
The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol.
About 250 million years ago, at the end of the Permian, a major extinction event killed over 90 per cent of life on earth, including insects, plants, marine animals, amphibians, and reptiles. Ecosystems were destroyed worldwide, communities were restructured and organisms were left struggling to recover. This was the nearest life ever came to being completely wiped out.

On the morning of June 12, 1990, Chris McKinstry went looking for a gun. At 11 am, he walked into Nick's Sport Shop on a busy street in downtown Toronto and approached the saleswoman behind the counter. "I'll take a Winchester Defender," he said, referring to a 12-gauge shotgun in the display. She eyeballed the skinny 23-year-old and told him he'd need a certificate to buy it.
Two and a half hours later, McKinstry returned, claiming to have the required document. The clerk showed him the gun, and he handled the pistol grip admiringly. Then, as she returned it to its place, he grabbed another shotgun from the case, yanked a shell out of his pocket, and jammed it into the chamber.
Robots can
evolve to communicate with each other, to help, and even to deceive each other, according to Dario Floreano of the Laboratory of Intelligent Systems at the Swiss Federal Institute of Technology.
If Idoya could talk, she would have plenty to boast about. On Thursday, the 12-pound, 32-inch monkey made a 200-pound, 5-foot humanoid robot walk on a treadmill using only her brain activity.
Beaumont-Hague, France - Thousands of canisters of highly radioactive waste from the world's most nuclear-energized nation lie, silent and deadly, beneath this jutting tip of Normandy. Above ground, cows graze and Atlantic waves crash into heather-covered hills.

Scientists have found what they say is the first evidence of a volcanic eruption under the Antarctic ice sheet.
They believe the volcano erupted about 2,000 years ago, and would have burst through its ice covering, producing a burst of steam and rocky debris.

Berlin -- A cargo ship pulled by a giant, parachute-shaped kite will leave Germany on Tuesday on a voyage that could herald a new "green" age of commercial sailing on the high seas.
It isn't scientific investigation of Darwinism that's forbidden -- it's public debate of the findings of such research. Most educated, rational people will find it almost impossible to believe that the debate of Darwinism through mainstream news papers and the principal TV channels is forbidden. I still find it hard to believe myself.
The article below was first commissioned and later censored by the Times Higher Education Supplement. (The circumstances under which it came to be censored, following the intervention of Dr Richard Dawkins, are described in the pages on Scientific Censorship).
The readers of the Times Higher Education Supplement (a large proportion of the University lecturers of Britain) have thus been prevented from learning of its contents. Now you have the facts before you and can make up your own mind.
