A foot in the door to genetic information

In the cell nucleus, DNA wraps around what are called histone proteins, forming regularly spaced spherical bodies called nucleosomes. Thus, large portions of the genetic material are inaccessible to the gene reading machinery. ...

Magnetic actuation enables nanoscale thermal analysis

Polymer nano-films and nano-composites are used in a wide variety of applications from food packaging to sports equipment to automotive and aerospace applications. Thermal analysis is routinely used to analyze materials for ...

Killer paper for next-generation food packaging

Scientists are reporting development and successful lab tests of "killer paper," a material intended for use as a new food packaging material that helps preserve foods by fighting the bacteria that cause spoilage. The paper, ...
