‘Amplified’ nanotubes may power the future
July 15, 2011

A single carbon nanotube before and after amplification (credit: Barron Lab/Rice University)Scientists at Rice University say they have achieved a pivotal breakthrough in the development of a carbon nanotube-based electrical cable that will make an efficient electrical grid of the future possible, a prediction made in 2004 by carbon nanotube co-inventor Richard E. Smalley. A prime technical hurdle in the development of this “miracle cable,” said Rice … more…


Brain responses to androids in the ‘uncanny valley’
July 15, 2011

uncanny androidIn an in-depth study of the “uncanny valley” phenomenon, an international team of researchers led by the University of California, San Diego has imaged the brains of people viewing videos of an “uncanny” android (compared to videos of a human and a robot-looking robot). The term “uncanny valley” refers to an artificial agent’s (such as a … more…


Meditation may change brain’s physical structure, strengthen connections
July 15, 2011

Meditation may have potential to change the brain’s physical structure, researchers at the University of California, Los Angeles, have found. People who meditate have stronger connections between brain regions and show less age-related brain atrophy, according to the researchers. Stronger connections influence the ability to rapidly relay electrical signals in the brain. And significantly, these … more…


Making chips one atom at a time
July 15, 2011

atoms_for_chipsAs logic chips scale down to the 22nm node and beyond, the heart of the transistor gate structure, its dielectric film stack, is becoming so thin that it must be atomically engineered. To meet this challenge, Applied Materials, Inc. has created advanced atomic layer deposition (ALD) technology, which builds ultra-thin, hafnium-based layers less than 2nm in thickness, … more…

The researchers developed a process for producing biomimetic scaffolds that closely emulate endogenous (within the body) tissue. This process allows the fabrication … more…


How to convert human skin cells into neurons
July 14, 2011

The addition of two particular gene snippets to a skin cell’s usual genetic material is enough to turn that cell into a fully functional neuron, researchers from the Stanford University School of Medicine have found. Scientists discovered two years ago that they could get similar results if they transformed the skin cell first into a … more…


Researchers demystify a fountain of youth in the adult brain
July 14, 2011

A “fountain of youth” that sustains the production of new neurons in the brains of rodents may also be present in the human brain, researchers at Duke University Medical Center have found. The existence of a vital support system of cells around stem cells in the brain explains why stem cells by themselves can’t generate … more…

Google is destroying your memory
July 15, 2011 by Amara D. Angelica

(Credit: iStockphoto)Well, OK, maybe not totally destroying it, just making it unnecessary to rely on friends, libraries, books, notes, and other forms of “transactive memory” (external systems), thanks to the rise of Internet search engines, Wikipedia, and other Internet tools. So says Columbia University psychologist Betsy Sparrow, co-author of an article in Science Express. “Since the advent … more…


How to preserve competing memories by zapping your brain

Off with their heads! (Credit: Walt Disney Pictures)Biologists at Indiana University have discovered why it takes two to tango. (Insert obligatory geeks-who-can’t-get-a-date joke here.) The biologists claim their research shows that sex allows parents to produce offspring that are more resistant to co-evolving parasites, while self-fertilization dooms populations to extinction at the hands of their biological enemies. It’s the Red Queen hypothesis, a … more…
