New molecular technologies, some driven by the work of a researcher at the University of Illinois at Urbana-Champaign, are exposing unexpectedly high levels of DNA folding and complex protein-rich assemblages within the nucleus of cells that he says "seriously challenge the textbook models."
"What we are seeing suggests that there may be machinery, not yet identified, that controls the folding and the movements of enzymes that turn genes on and off," said Andrew Belmont, a professor of cell and structural biology, who is giving a talk on the subject today at the annual meeting of the American Association for the Advancement of Science.
Belmont, who also is a medical doctor, discussed current trends of research on chromatin structure during a session on "The New Nucleus: Mothership of the Human Genome." Chromatin is a part of a cells nucleus that contains nucleic acids and proteins -- the genetic material necessary for cell division. During mitosis, chromatin folds and condenses.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
