By bridging the realms of nucleic acids and proteins, peptide nucleic acid (PNA), a synthetic hybrid of protein and DNA, could form the basis of a new class of drugs -- and of artificial life unlike anything found in nature.It might be able to serve both as a store of information, like DNA, and as the catalytic machinery of an artificial cell, like the many protein-based enzymes in natural cells.

A search for colossal feats of alien engineering called "Dyson spheres" has so far found no convincing candidates within 1000 light years of Earth, but Richard Carrigan, formerly with the Fermi National Accelerator Laboratory, has combed through data from the Infrared Astronomical Satellite and has identified 17 possible "spheres," four of which seem most promising.((Illustration: Vedexent/Wikimedia Commons) (Source: http://www.newscientist.com/...

Intel Labs researchers say they have achieved an important new step in developing silicon photonics (transmitting data via light): a silicon-based avalanche photodetector, or APD, that detects and amplifies light signals. An avalanche photodetector is a sensor that both detects light pulses and amplifies them as light is directed into the silicon. Unlike other photodetectors that absorb one photon pulse and produce one electron, an APD can absorb ... More

Intel Labs is developing a "wireless identification and sensing platform," or WISP, using self-powered microchips that could be implanted in the human body, a mobile phone, a building, or anyplace else where people wish to gather information.Self-powered sensors could one day go into the human body to monitor health-related activity, such as the beat of a heart, says Intel CTO Justin Rattner. If researchers could shrink detectors to the molecular ... More

Rather than infer that nanotechnology is safe, members of the public who learn about this novel science tend to become sharply polarized along cultural lines, according to a study conducted by the Cultural Cognition Project at Yale Law School in collaboration with the Project on Emerging Nanotechnologies. The report is published online in the journal Nature Nanotechnology.

(Emory University) The first generation of quantum dots were made from the toxic heavy metal cadmium and had emission wavelengths, and colors, determined by their size. "Lattice strain" created by layers of different semiconductor materials allows the color of quantum dots to be tuned independent of size. Small enough to pass through the kidneys if administered systemically, the new quantum dots are expected to be useful for cancer detection and p... More

Amazon Web Services, a subsidiary of Amazon.com, has started offering access to large collections of data. Business customers and scientists can take the information, which ranges from census databases to three-dimensional chemical structures and the genome, and use it as the basis for computing jobs. By gathering and storing the information, Amazon says that it can save businesses the step of assembling and managing data on their own. (Source: ... More

University of California, Berkeley scientist Ben Freivogel combined the cosmological models of large-scale structure formation with the physics of dark-matter axions to predict the most likely value for the ratio of dark matter to normal matter that would allow observers like us to emerge, assuming that the number of observers in a universe is proportional to the number of galaxies within it.Supporting the antropic principle, his calculations show...

University of Barcelona researchers have developed a microscopic swimming machine that works like a paddle steamer; it could help deliver drugs inside the body and move chemicals around inside miniaturized labs.They coated two beads in a protein called streptavidin that binds strongly to DNA and then fastened them together with two 8-nanometer strands of DNA, controlled by a rotating magnetic field. The team believes its technology can easily be s... More

A new browser tool called Zoetrope from Adobe Systems allows users to browse backward through time. Zoetrope will recognize a price as it goes up or down and will show the results as a graph. It's also possible to draw lenses on different websites and sync them in order to carry out a historical comparison.Video (Source: http://www.technologyreview.com/web/21769/?a=f)

The gene for tryptophan hydroxylase-2, which makes the brain chemical serotonin, is being linked to increased susceptibility to the placebo effect, based on an experiment at Uppsala University. The effect of the gene may extend to other conditions where the amygdala is involved, such as phobias, pain disorders and even depression.
