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 at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
