Electronic tattoo display runs on blood

Jim Mielke's wireless blood-fueled display is a true merging of technology and body art. At the recent Greener Gadgets Design Competition, the engineer demonstrated a subcutaneously implanted touch-screen that operates as a cell phone display, with the potential for 3G video calls that are visible just underneath the skin.

20 Fascinating Ancient Maps

Works of art in and of themselves, these ancient maps reveal a great deal more than the geographical knowledge of our ancestors. They tell stories of war and triumph, reveal myths and biases, and document modes of thought that have long been obsolete.

DNA Not The Same In Every Cell Of Body: Major Genetic Differences Between Blood And Tissue Cells Revealed

Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation.

This discovery may undercut the rationale behind numerous large-scale genetic studies conducted over the last 15 years, studies which were supposed to isolate the causes of scores of human diseases.

Adult brain can change within seconds

The human brain can adapt to changing demands even in adulthood, but MIT neuroscientists have now found evidence of it changing with unsuspected speed. Their findings suggest that the brain has a network of silent connections that underlie its plasticity.

"So the visual cortex changes its response almost immediately to sensory deprivation and to new input," Kanwisher explained. "Our study shows the stunning ability of the brain to adapt to moment-to-moment changes in experience even in adulthood."

Why do dogs bark?

Not Only Dogs, But Deer, Monkeys And Birds Bark To Deal With Conflict.

Biologically speaking, many animals besides dogs bark, according to Kathryn Lord at the University of Massachusetts Amherst, but the evolutionary biologist also says domestic dogs vocalize in this way much more than birds, deer, monkeys and other wild animals that use barks. The reason is related to dogs’ 10,000-year history of hanging around human food refuse dumps, she suggests.

The Wonderful World of Big Science

For most of its history, science has always been done by individual or at best a small group of scientists. World War II changed that: during the war, government-sponsored laboratories employing thousands of scientists sprung up to do large-scale research on weapons and technology. Since then, scientific research has entered a new era dubbed "Big Science".

Whether "big" science is any better than "small" science is a matter of controversy. Director of Oak Ridge National Laboratory Alvin Weinberg (who coined the term "Big Science" in the 1960s) defended the organization and big-budget financing of Big Science as the only way to continue research into progressively more complex scientific matters. On the other hand, science historian Paul Forman posited that defense-related funding by the government shifted the focus in physics from basic to applied research.

Whatever the answer, Big Science is here to stay. So let’s take a look at some of the biggest Big Science projects in the World:

Why You Can’t Keep Your Foot Out of Your Mouth

Using ingenious experiments to reveal the brain’s hidden machinations, Wegner and others have found that our brains expend steady, conscious effort to avoid talking about ex-girlfriends on first dates, sending putts off the green, or letting slip the real reason you were late for work.

But when our conscious minds are stressed and preoccupied — by, for example, a desire not to screw up — a subconscious process devoted to guarding against the mistake slips through. Unwanted thoughts pop into the forefront of your mind.

The Weird, Wacky World of The Platypus

Long has the platypus been referred to as a “freak” or a “joke by God.” But darn it, these critters are awesome, interesting and unique. If anything, they’re really super animals and everyone else is just jealous. After all, they take a little bit of all kinds of good animals and make one excellent and one-of-a-kind family of animals.

Yes, I Suck: Self-Help Through Negative Thinking

In the past 50 years, people with mental problems have spent untold millions of hours in therapists' offices, and millions more reading self-help books, trying to turn negative thoughts like "I never do anything right" into positive ones like "I can succeed." For many people — including well-educated, highly trained therapists, for whom "cognitive restructuring" is a central goal — the very definition of psychotherapy is the process of changing self-defeating attitudes into constructive ones.

But was Norman Vincent Peale right? Is there power in positive thinking? A study just published in the journal Psychological Science says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.

New wonder material, one-atom thick, has scientists abuzz

Imagine a carbon sheet that's only one atom thick but is stronger than diamond and conducts electricity 100 times faster than the silicon in computer chips.

That's graphene, the latest wonder material coming out of science laboratories around the world. It's creating tremendous buzz among physicists, chemists and electronic engineers.

"It is the thinnest known material in the universe, and the strongest ever measured," Andre Geim , a physicist at the University of Manchester, England , wrote in the June 19 issue of the journal Science.

A pill for longer life?

Rapamycin, a drug commonly used in humans to prevent transplanted organs from being rejected, has been found to extend the lives of mice by up to 14% — even when given to the mice late in life.

In flies and worms, drug treatments have been shown to prolong lifespan, but until now, the only robust way to extend life in mammals has been to heavily restrict diet.

The researchers caution, however, that using this drug to extend the lifespan of humans might be problematic because it suppresses the immune system — potentially making people who take it more susceptible to infectious diseases.

Oldest known Bible goes online

LONDON, England (CNN) -- The world's oldest known Christian Bible goes online Monday -- but the 1,600-year-old text doesn't match the one you'll find in churches today.

Discovered in a monastery in the Sinai desert in Egypt more than 160 years ago, the handwritten Codex Sinaiticus includes two books that are not part of the official New Testament and at least seven books that are not in the Old Testament.

The New Testament books are in a different order, and include numerous handwritten corrections -- some made as much as 800 years after the texts were written, according to scholars who worked on the project of putting the Bible online. The changes range from the alteration of a single letter to the insertion of whole sentences.

Five Myths about America’s Origins

As students of American history, most children learn about the heroes of the Revolutionary War, the discovery of the American continent, and other stories that illuminate the courageous people who contributed to the formation of the United States. In learning about Christopher Columbus, Benjamin Franklin, and George Washington, we’re regaled with stories of their personal valor—how Washington chopped down his cherry tree, how Columbus proved the flat-earthers wrong, and how Franklin discovered electricity in a lightning storm.

We learn all these quaint and quixotic stories, despite the fact that not one of them is true. George Washington never chopped down a cherry tree; geological evidence from his boyhood home shows that no cherry trees have ever grown there. A preacher looking to sell books propagated the story. As we prepare for our country’s 233rd birthday, we should think about the fact that many of the stories sold as historical fact would be better categorized as sheer fiction.

How to build a bigger brain

Push-ups, crunches, gyms, personal trainers — people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?

Meditate.

That's the finding from a group of researchers at UCLA who used high-resolution magnetic resonance imaging (MRI) to scan the brains of people who meditate. In a study published in the journal NeuroImage and currently available online (by subscription), the researchers report that certain regions in the brains of long-term meditators were larger than in a similar control group.

8 Science Kit Reviews and 8 DIY Experiments You Can Do for Free

Science kits aren't what they used to be. If you look at a kit from, say, 1950, you may notice that it is full of complex, mechanical parts, requires adult supervision just to read the directions and doesn't shy away from including dangerous elements (u-238 included!). Modern-day kits don't dumb lessons down, but are easier to play with, solo, and appeal to the diverse, real-world interests of contemporary kids. Being big, curious kids ourselves, we ordered eight kits on different subjects and tested an experiment from each. But homemade experiments can be just as complex and educational (while costing up to $100 less), so we found alternatives to each of the boxed kits that teach similar lessons just as well. Bottom line: Whether preassembled or drawn from kitchen cupboards, science kits can be educational and fun.

World's first ever 'self-watering' plant discovered in Israel

The Desert Rhubarb can hold 16 times more water than its rivals and has developed a unique ability to effectively water itself in its barren habitat.

Researchers were confounded by the metre-wide plant's giant leaves, compared to its desert counterparts, whose tiny leaves stop dangerous moisture loss.

But they found the plant's large leaves are the key to its success, because they are covered in microscopic streams through which water can be channelled.
