First potentially habitable Earth-sized planet confirmed: It may have liquid water. 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. " Human brains share a consistent genetic blueprint and possess enormous biochemical complexity. Home : Scientific Reports.

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. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? 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. Recent advances in functional neuroimaging – a technique that measures brain activity in the hope of finding correlations between mental functions and specific regions of the brain – have led to a wealth of studies that map particular functions onto regions.
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. They call this circuit diagram the “connectome”, and it could help us better understand everything from imagination and language to the miswirings that cause mental illness.

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. 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. DNA consists of long strings of “letters” that code for specific amino acids. Why Nikola Tesla was the greatest geek who ever lived.
Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla.
Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too. 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. To see that list go here. I remember as a kid of about eight years old, discovering my love for astronomy. 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 cycle for lows and highs of solar activity occur roughly every 11 years. We are now experiencing recent solar flares which have unleashed Coronal Mass Ejections (CME) and once again we are experiencing Northern Lights that we have not seen (at least at lower latitudes) for many years.

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.
