Can you make yourself smarter?
The New York Times

Early on a drab afternoon in January, a dozen third graders from the working-class suburb of Chicago Heights, Ill., burst into the Mac Lab on the ground floor of Washington-McKinley School in a blur of blue pants, blue vests and white shirts. Minutes later, they were hunkered down in front of the Apple computers lining the room's perimeter, hoping to do what was, until recently, considered impossible: increase their intelligence through training.

Making education brain science
The New York Times
Share
Two kindergarten classes were hard at work doing what many kindergartners do: drawing. One group pursued a variation on the self-portrait. "That's me thinking about my brain," one 5-year-old-girl said of her picture. Down the hall, children with oil pastels in hand were illustrating their emotions, mapping where they started and where they ended. For one girl, sadness ended at home with a yummy drink and her teddy bear.

Ravens remember relationships they had with others
ScienceDaily
Share
In daily life we remember faces and voices of several known individuals. Similarly, mammals have been shown to remember calls and faces of known individuals after a number of years. Markus Boeckle and Thomas Bugnyar from the Department of Cognitive Biology of the University of Vienna show in their recent article, published in Current Biology, that ravens differentiate individuals based on familiarity.

I remember Mama and Dada

Nicholas Day writes, "What do small children remember? And why do memories stick into adulthood? Last August, I moved across the country with a child who was a few months shy of his third birthday. I assumed he'd forget his old life — his old friends, his old routine — within a couple of months. Instead, over a half-year later, he remembers it in unnerving detail: the laundromat below our apartment, the friends he ran around naked with, my wife's co-workers. I just got done with a stint pretending to be his long-abandoned friend Iris — at his direction."

Bigger brain and higher IQ linked with specific genetic variants
TIME
Share
Researchers have identified two genes that affect brain size and may be linked not only to IQ, but also to our risk of developing brain disorders like Alzheimer's disease.
Scientists have known for some time that the size and volume of certain parts of the brain are linked to disorders including developmental conditions such as autism and degenerative diseases like Alzheimer's.

Physicists create first long-distance quantum link
ScienceNOW
Share
For more than a decade, physicists have been developing quantum-mechanical methods to pass secret messages without fear that they could be intercepted. But they still haven't created a true quantum network - the fully quantum-mechanical analog to an ordinary telecommunications network in which an uncrackable connection can be forged between any two stations or "nodes" in a network. Now, a team of researchers in Germany has built the first true quantum link using two widely separated atoms. A complete network could be constructed by combining many such links, the researchers say.

Polar bears older than previously thought
ScienceNews
Share
Polar bears might have originated about 600,000 years ago, an international team reports April 20 in Science.
Previously, studies suggested that the polar bear, Ursus maritimus, emerged much later, about 150,000 years back.

Study shows how brain tunes out background noise, hears one voice
The Los Angeles Times
Share
In some ways, parties seem like the worst possible places to socialize. A cacophony of voices — not to mention a blaring stereo system — make for a noisy environment in which to hear what a friend is saying.
Hence the term "the cocktail-party effect," which refers to people's ability to focus on one speaker and tune out another.

For the first time, electrons are observed splitting into smaller quasi-particles
Popular Science
Share
We generally think of electrons as fundamental building blocks of atoms, elementary subatomic particles with no smaller components to speak of. But according to Swiss and German researchers reporting in Nature, we are wrong to think so. For the first time, the researchers have recorded an observation of an electron splitting into two different quasi-particles, each taking different characteristics of the original electron with it.

3,000 ancient Buddhas unearthed in China

The head of a Buddha statue peeks above the dirt in Handan, China, where archaeologists have reportedly unearthed nearly 3,000 Buddha statues, which could be up to 1,500 years old.
The discovery is believed to be the largest of its kind since the founding of the People's Republic of China in 1949, an archaeologist with the Chinese Academy of Social Sciences told reporters in late March, according to the Associated Press.
