"The Most Complex Organ in the Milky Way?" --New Insights Into the Enormous Biochemical Complexity of the Human Brain "Consider the human brain," says physicist Sir Roger Penrose. "If you look at the entire physical cosmos, our brains are a tiny, tiny part of it. But they're the most perfectly organized part. Compared to the complexity of a brain, a galaxy is just an inert lump."
The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour.
Location of the mind remains a mystery - life - 22 August 2012 Where does the mind reside? It's a question that's occupied the best brains for thousands of years. Now, a patient who is self-aware – despite lacking three regions of the brain thought to be essential for self-awareness – demonstrates that the mind remains as elusive as ever. The finding suggests that mental functions might not be tied to fixed brain regions. Instead, the mind might be more like a virtual machine running on distributed computers, with brain resources allocated in a flexible manner, says David Rudrauf at the University of Iowa in Iowa City, who led the study of the patient.
When you have no clue, call it glue. “Glia,” the Greek word for glue, was the name the pathologist Rudolph Virchow gave, back in 1856, to the gelatinous substance that forms the bulk of the brain. And it stuck. These days, scientists use it to denote the matter that accounts for 90 percent of the brain’s cells and more than half its volume — but, like the late comic Rodney Dangerfield, “can’t get no respect.” Neurons, the “talented tenth” of the human brain that hog the lion’s share of brain scientists’ attention, are indeed a work of evolutionary art. They’ve got a knack that glia lack: Their aptitude for high-speed, long-distance communication makes them the nervous system’s premier information processors.
We knew anatomy could be gorgeous, but this is beyond anything else we’ve ever seen, and it’s guaranteed to be something you haven’t seen, being the first 3D image of a brain’s connections. Van Wedeen, a Harvard radiology professor, is awestruck: “We’ve never really seen the brain – it’s been hiding in plain sight.” Conventional scanning has offered us a crude glimpse, but scientists such as Wedeen aim to produce the first ever three-dimensional map of all its neurons.
Allen Institute for Brain Science: Science: Overview Our brains are what make us human. They give rise to our thoughts, actions, movements and desires, store our memories, and enable us to navigate our world every day. Yet despite decades of research—and impressive knowledge gathered about other aspects of the human body, including our entire genetic sequence—the brain remains largely a mystery. The Allen Institute was established to answer some of the most pressing questions in neuroscience, grounded in an understanding of the brain and inspired by our quest to uncover the essence of what makes us human. Using a “big science” approach, the Allen Institute enables the global scientific community to more efficiently make discoveries that bring real-world utility.

Incredible close-up shot of living human brain wins microscope photography competition | Mail Online By Eddie Wrenn Published: 11:02 GMT, 26 June 2012 | Updated: 11:17 GMT, 26 June 2012 A unique close-up image of a living human brain has won the Wellcome Prize for microscope photography after it was taken during a surgical procedure to treat a patient with epilepsy. Taken by Robert Ludlow of UCL's Institute of Neurology, the image is a rare shot of a living brain - a view normally only seen by neurosurgeons, showing veins, arteries and grey matter flushed pink with blood. Professor Alice Roberts, who was a member of the judging panel, said: ‘This is a remarkable image of a human brain.
MIT and Harvard researchers have developed technologies that could be used to rewrite the genetic code of a living cell, allowing them to make large-scale edits to the cell’s genome. Such technology could enable scientists to design cells that build proteins not found in nature, or engineer bacteria that are resistant to any type of viral infection. The technology, described in the July 15 issue of Science, can overwrite specific DNA sequences throughout the genome, similar to the find-and-replace function in word-processing programs. Using this approach, the researchers can make hundreds of targeted edits to the genome of E. coli, apparently without disrupting the cells’ function.
Space It is funny how researching lists can send you off in other directions. Here is a classic example. I started researching this list and when I looked up information about the upcoming Venus transit, I realized there was enough great information to do an entire list just on that topic. 10 Upcoming Astronomical Events Worth Seeing

The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life. The abolitionist project is hugely ambitious but technically feasible. It is also instrumentally rational and morally urgent.
