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. " Home : Scientific Reports. The Last 24 Hours. 100 Very Cool Facts About The Human Body - Global One TV. 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. The brain’s silent majority - 2009 FALL. 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. First 3D Map of the Brain’s Connections. 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. 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. Scientists unveil tools for rewriting the code of life. 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. “We did get some skepticism from biologists early on,” says Peter Carr, senior research staff at MIT’s Lincoln Laboratory (and formerly of the MIT Media Lab), who is one of the paper’s lead authors. Why Nikola Tesla was the greatest geek who ever lived. Professor of Theoretical Physics, CUNY. 10 Upcoming Astronomical Events Worth Seeing.
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. Partial Solar Eclipse Sunset Seen In Colorado. Aurora / Meteor Shower Images. Aurora / Meteor Shower Images Update: We have now come out of one of the lowest Solar Minimums on record.

The Hedonistic Imperative. Atomic-scale magnetic memory. The world's smallest bit Scientists from IBM Research have been investigating and controlling matter on an atomic scale for decades. So, naturally, their latest quest would involve greatly decreasing the storage capacity needed for one bit of data, which on today's computers stands at about 1 million atoms. They set out to develop the ultimate memory chips of the future. Starting at the very beginning of density—single atoms—they created the world’s smallest magnetic memory bit and answered the question of how many atoms it takes to reliably store one bit of magnetic information at a low temperature: 12.
The Year in Volcanic Activity - Alan Taylor - In Focus. Out of an estimated 1,500 active volcanoes around the world, 50 or so erupt every year, spewing steam, ash, toxic gases, and lava. In 2011, active volcanoes included Chile's Puyehue, Japan's Shinmoedake, Indonesia's Lokon, Iceland's Grímsvötn, Italy's Etna, and recently Nyamulagira in the Democratic Republic of Congo. In Hawaii, Kilauea continues to send lava flowing toward the sea, and the ocean floor has been erupting near the Canary Islands.
Collected below are scenes from the wide variety of volcanic activity on Earth over the past year.
