The neurotransmitter Neuropeptide Y (NPY) directly controls osteoblasts, the cells that make bone in mice, a neuroscientist from Sydney's Garvan Institute of Medical Research, has demonstrated. When we are starving, our brains don't allow us to waste energy by reproducing, making fat or creating new bone. When we are eating too much, on the other hand, our brains make it easier to reproduce, store fat and create bone. (Source: http://www.physor... More

Slashdot reports: "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. "Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet ... More

An online game promoting the new movie Sherlock Holmes allows players to use natural language in their typed interrogations.Unlike keyword recognizers, the game uses statistical analysis and fuzzy logic to try to find the best match for what was said against a vast number of predictions before supplying the appropriate response.To solve the mystery (via Facebook), players must collect clues and use them to decide which questions they ask the virtu...

University of Rochester researchers used the placebo effect to successfully treat psoriasis patients with one quarter to one half of their usual dose of a widely used steroid medication.The new technique could improve treatment for several chronic diseases that involve mental state or the immune system, by mixing active drug and placebo (also making possible a dramatic and timely reduction in healthcare costs).The researchers suggest that the drug...

(University of Copenhagen) New nano research gives important insights in nerve cell communication that will help the fight against nerve pain following amputation and diabetes. Researchers from the University of Copenhagen have studied, with nanotechnology techniques, the way proteins recognize the small membrane vesicles that transmit signaling molecules from one nerve cell to another.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have found a new way to use a synthetic form of double-stranded DNA for programmable self-assembly of nanoparticles. It could allow for switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage.

Researchers at Harvard and Stanford University have reported a new technique for genetic analysis using nanomechanical response of hybridized DNA/RNA molecules.* A new type of nanoscale sensor feels the stiffness of DNA molecules on a microarray to distinguish the ones that formed the double helix, with digital precision.This technique is several orders of magnitude more sensitive than other approaches (such as fluorescent labels) and could allow ...

Caltech researchers have proposed a method of suppressing environmental noise (such as random thermal and mechanical vibrations) to observe quantum superposition and entanglement in progressively larger and more complex systems.They propose to "levitate" a nanosphere using laser beams. The light that bounces back and forth between the mirrors both senses the motion of the sphere and is used to manipulate that motion at a quantum-mechanical level.T... More
