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.

Mapping dark matter, 4.5 billion light years away

Galaxy cluster MCS J0416.1–2403, one of six clusters targeted by the Hubble Frontier Fields programme. The blue in this image is a mass map created by using new Hubble observations combined with the magnifying power of a process known as gravitational lensing. In red is the hot gas detected by NASA’s Chandra X-Ray Observatory and shows the location of the gas in the cluster. The matter shown in blue that is separate from the red areas detected by Chandra consists of what is known as dark matter, and which can only be detected directly by gravitational lensing.

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.
