• "Concepts..." is a tough book to put down; a melange of serious thinking and humor. (15)


Original Einstein manuscripts show first details of E=MC2
The Associated Press via Fox News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Albert Einstein's complete archives — from personal correspondence with half a dozen lovers to notebooks scribbled with his groundbreaking scientific research — are going online for the first time. The Hebrew University of Jerusalem, which owns the German Jewish physicist's papers, is pulling never-before seen items from its climate-controlled safe, photographing them in high resolution and posting them on the Internet — offering the public a nuanced and fuller portrait of the man behind the scientific genius.

Researchers show that memories reside in specific brain cells
MIT News Office    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams. More

Mercury has a liquid core, and other new surprises from the innermost planet
Popular Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
NASA's Messenger spacecraft entered orbit around Mercury one year ago, and the spacecraft has been hard at work. It has captured nearly 100,000 images, mapped Mercury's gravity field and taken sensitive altimetry measurements that are shedding light on the planet's surface features like never before. Scientists on the Messenger mission published another round of new findings about the innermost planet, which turns out to be an altogether weirder world than we'd thought. More

Laser-tuned nuclear clock would be accurate for billions of years
Wired    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have proposed building a nuclear clock that would lose only one-tenth of a second over 14 billion years, the current age of the universe. The design would be 100 times more accurate than current atomic clocks and might be used in applications such as higher-precision GPS satellites and experiments that probe fundamental physics. More

Brain handles odors in a different way
redOrbit    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers from the Stowers institute for Medical Research have traced individual odor molecules in the brain to create a new model of how our sense of smell works. While once thought to cluster related smells, researchers have know discovered that the brain reacts to smells in a broader sense. Previous research has shown that the brain handles the senses in a very orderly way. More

Seeing movement: Why the world in our head stays still when we move our eyes
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When observing a fly buzzing around the room, we should have the impression that it is not the fly, but rather the space that lies behind it that is moving. After all, the fly is always fixed in our central point of view. But how does the brain convey the impression of a fly in motion in a motionless field? With the help of functional magnetic resonance imaging (fMRI), scientists from the Werner Reichardt Centre for Integrative Neuroscience and the Max Planck Institute for Biological Cybernetics in Tübingen have identified two areas of the brain that compare the movements of the eye with the visual movements cast onto the retina so as to correctly perceive objects in motion.

Scientists wrest partial control of a memory
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scripps Research Institute scientists and their colleagues have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to weaken harmful thoughts for those with conditions such as schizophrenia and post traumatic stress disorder.

T. rex bite strongest ever on land — 10 times greater than gator's
National Geographic    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Once the largest known carnivore on land, Tyrannosaurus rex also had the most powerful bite of any terrestrial animal of any time period, a new study suggests. Much conventional wisdom about the world's most famous dinosaur species has been called into question in recent years—for instance, whether the 40-foot-long T. rex species could run or only plod along.

How 5 super-rich places got such fancy names
Mental Floss    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Martha's Vineyard, a regular presidential vacation destination and home to the Kennedy family, owes its name to the prolific explorer Bartholomew Gosnold. Gosnold did a number of extraordinary things in his short life. He gave both Martha's Vineyard and Cape Cod their names. More

Globe-trotting gnome highlights Earth's weird gravity
LiveScience    Share    Share on FacebookTwitterShare on LinkedinE-mail article
There aren't too many gardens at the South Pole. But there are, apparently, garden gnomes. A globe-trotting little garden gnome dubbed "Kern" recently visited Amundsen-Scott Research Station at the geographic South Pole in Antarctica. The inanimate traveler's trip was a take on the "Traveling Gnome Prank," a joke that's been in vogue since the 1980s, when pranksters started stealing garden gnomes and sending photographs of the statuettes in front of famous sightseeing spots to their owners.
