A team of scientists say they have discovered a method for attaching molecules to semiconducting silicon that may help manufacturers end-run the current limits of Moore's Law in the quest to make microprocessors smaller and more powerful.  Moore's Law is named after Intel co-founder Gordon Moore who said in 1965 that the number of transistors that can be placed on an integrated circuit doubles about every two years. But even Moore said the law cannot be sustained indefinitely.  Or can it?
Some researchers, and certainly some new businesses, are counting on the fact that the brain imaging technique known as functional magnetic resonance imaging (fMRI) can reveal thoughts and determine if someone is lying or telling the truth - and maybe even their hidden deep desires. 

Is there something to it?   It depends.

Neuroscientists at UCLA and Rutgers University say they have evidence that fMRI can be used in certain circumstances to determine what a person is thinking but their research suggests that highly accurate "mind reading" using fMRI is still far from reality.
There's a coevolutionary struggle between a New Zealand snail and its worm parasite but it ends up being sexually advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, according to scientists who say their report represents direct experimental evidence for the "Red Queen Hypothesis" of sex, suggesting sexual reproduction allows host species to avoid infection by their coevolving parasites by producing genetically variable offspring.

They say their Current Biology report also supports the "Geographic Mosaic Theory," meaning natural selection need not act uniformly on all members of a species, but can be intense in pockets of a population (hot spots) and absent elsewhere (cold spots).
A group called the Blind Driver Challenge team in Virginia Tech's Robotics and Mechanisms Laboratory  has retrofitted a four-wheel dirt buggy with laser range finders, an instant voice command interface and a host of other cutting-edge technologies.

Does it sound like Knight Rider's KITT or something out of a Terminator movie?   Only if those drivers are blind.

It's still in the early testing stage but the National Federation of the Blind considers the vehicle a major breakthrough for independent living of the visually impaired. 
Scientists in Nevada are reporting development of a new and environmentally friendly process for chicken parts that are a lot better for you than Chicken Nuggets - namely, producing biodiesel fuel from 'chicken feather' meal, the 11 billion pounds of poultry industry waste that accumulate annually in the United States alone.

In the study Mano Misra, Susanta Mohapatra, Narasimharao Kondamudi, and Jason Strull used chicken feather meal, which consists of processed chicken feathers, blood, and innards that have been processed at high temperatures with steam.
University of Utah School of Medicine researchers and their colleagues at University of Texas (UT) Southwestern Medical Center have found strong evidence that abnormal calcium signaling in neurons may play an important role in the development of spinocerebellar ataxia type 2 (SCA2), a disorder causing progressive loss of coordination, speech difficulty, and abnormal eye movements. Their findings are published in the Journal of Neuroscience.

SCA2 is an inherited neurodegenerative disease that predominantly affects neurons called Purkinje cells in the cerebellum, the region of the brain that controls voluntary muscle movements, balance, and posture. It is one of a group of genetic disorders characterized by ataxia, or loss of muscle coordination.
