New imaging agent provides better picture of the gut

A multi-institutional team of researchers has developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases.

From Narrow to Broad

Electromagnetic absorbers based on plasmonic and metamaterial structures are of great interest for many areas as narrowband absorbers. A variety of approaches have been proposed to achieve broadband absorption, which is needed for applications such as solar energy harvesting.

ALMA Finds Double Star with Weird and Wild Planet-forming Discs

eso1423a_0.jpg
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary discs in a double star. The new result also helps to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits.

FEI adds Phase Plate Technology and Titan Halo TEM to its Structural Biology Product Portfolio: New solutions provide the high-quality imaging and contrast necessary to analyze the 3D structure of molecules and molecular complexes

FEI (NASDAQ: FEIC) announced two new products for cryo-electron microscopy applications: a new phase plate solution and the Titan Halo™ transmission electron microscope (TEM). The phase plate is a stable, durable solution to increase the contrast of sensitive biological samples and is available on most TEM platforms from FEI. The Titan Halo TEM provides high-quality optical performance with enhanced flexibility for multi-scale applications in life and biomaterials sciences. With these new products, researchers can now see more detail in their biological specimens, and potentially gain greater insight into the fundamental processes of living systems at the molecular scale.

Seeing is bead-lieving: Rice University scientists create model 'bead-spring' chains with tunable properties

Rice University researchers are using magnetic beads and DNA "springs" to create chains of varying flexibility that can be used as microscale models for polymer macromolecules.

DNA linkers serve as bridges between colloidal beads in a new experiment by Rice University scientists to study the physics of "bead-spring" polymer chains. They found the chains can be tuned for varying degrees of stiffness or flexibility.
