DNA motor 'walks' along nanotube, transports tiny particle Posted: 17 Dec 2013 12:53 PM PST Researchers have created a new type of molecular motor made of DNA and demonstrated its potential by using it to transport a nanoparticle along the length of a carbon nanotube. |
Exposing the roots of the lithium battery problem Posted: 17 Dec 2013 10:47 AM PST Researchers have discovered that the dendrite problem that can cause lithium-ion batteries to short-circuit, overheat and possibly catch fire originates below the surface of the lithium electrode and not at the surface as has been widely believed. |
Researchers develop advanced 3D 'force microscope' Posted: 17 Dec 2013 10:47 AM PST Researchers have developed a three-dimensional microscope that will yield unparalleled study of membrane proteins and how they interact on the cellular level. These microscopes could help pharmaceutical companies bring drugs to market faster. |
Posted: 17 Dec 2013 09:39 AM PST A new algorithm uses subtle changes to make a face more memorable without changing a person's overall appearance. |
Targeted synthesis of natural products with light Posted: 17 Dec 2013 09:39 AM PST Photoreactions are essential for the syntheses of many natural substances. Since many of these substances are also useful as active medical agents, chemists try to produce them synthetically. But in most cases only one of the possible products has the right spatial structure to make it effective. Researchers have now developed a methodology for one of these photoreactions that allows them to produce only the specific molecular variant desired. |
Fungal pathogen shows profound effects from spaceflight Posted: 17 Dec 2013 07:45 AM PST In a new study, the first global gene expression profiling and phenotypic characterization of a fungal pathogen during spaceflight is revealed. |
Sharpening focus in quantum photolithography Posted: 17 Dec 2013 07:44 AM PST Photolithography uses light beams to design thin geometric patterns on the substrates of semiconductors used in microelectronic devices. This is achieved using a chemical reaction on a light-sensitive chemical, called photoresist. The trouble is that the phenomenon of light diffraction does not permit highly accurate patterns. Now, a scientist has developed a quantum lithography protocol designed to improve the resolution of this technology. |
Infrared sheds light on single protein complexes Posted: 17 Dec 2013 07:42 AM PST Nanoscience researchers employ nano-FTIR spectroscopy for label-free chemical and structural imaging of proteins with nanoscale spatial resolution and with sensitivity to single protein complexes of less than one attogram (10-18 gram), and discuss these results in a recently published article. |
Hubble watches super star create holiday light show Posted: 17 Dec 2013 07:40 AM PST This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. Hubble took a series of photos of light flashes rippling across the nebula in a phenomenon known as a "light echo." |
Infrared sheds light on single protein complexes Posted: 17 Dec 2013 05:51 AM PST Researchers have used spectroscopy for label-free chemical and structural imaging of proteins with nanoscale spatial resolution and with sensitivity to single protein complexes of less than one attogram (10-18 gram). |
Massive stars mark out Milky Way's 'missing arms' Posted: 17 Dec 2013 05:50 AM PST A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms. |
Robotic training system helps patients recovering from conditions affecting balance Posted: 13 Dec 2013 01:11 PM PST Patients relearn to walk after stroke, spinal cord or brain injury often fear falling, which may inhibit their recovery. Robotic body weight support system provides adding security to maximize progress. |
New results make development of quantum computers more realistic Posted: 12 Dec 2013 06:56 AM PST New research will make the eventual development of the quantum computer more feasible. |
