Odd histone helps suppress jumping genes in stem cells, study says
A family of proteins known as histones provides support and structure to DNA, but for years, scientists have been puzzling over occasional outliers among these histones, which appear to exist for specific, but often mysterious reasons. Now, researchers have uncovered a new purpose for one such histone variant: preventing genetic mutations by keeping certain so-called "jumping genes" in place. This research, which began at Rockefeller University and was published May 4 in Nature, reveals a...

These gigantic whales have nerves like bungee cords
Nerves aren't known for being stretchy. In fact, "nerve stretch injury" is a common form of trauma in humans. But researchers reporting in

Tara Oceans expedition yields treasure trove of plankton data
In five related reports in this issue of the journal Science, a multinational team of researchers who spent three and a half years sampling the ocean's sunlit upper layers aboard the schooner Tara unveil the first officially reported global analyses of the Tara Oceans consortium. Planktonic life in the ocean is far more diverse than scientists knew, these reports show. They provide new resources for cataloguing the ocean's numerous planktonic organisms, which -- though critical to life on...

New mechanisms of self-organization in living cells
Chromosome is a structure inside the cell nucleus that carries a large part of the genetic information and is responsible for its storage, transfer and implementation. Chromosome is formed from a very long DNA molecule - a double chain of a plurality of genes. Given that the diameter of the cell nucleus is usually around hundredth of a millimeter or even less, while the total length of DNA constituting human genome is about two meters, it is clear that DNA must be packaged very...

Scientists find that cancer can arise from changes in the proteins that package DNA
In some cancers, including chondroblastoma and a rare form of childhood sarcoma, a mutation in histone H3 reduces global levels of methylation (dark areas) in tumor cells

Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published in in the early edition of the Proceedings of the National Academy of Sciences the week of May 26 and the May 30 issue of Physical Review Letters. DNA is a long, unwieldy molecule that tends to repel itself because it is negatively charged, yet it can spool tightly. Within the heads of...

Discovery shows how herpes simplex virus reactivates in neurons to trigger disease
When we get cold sores, the reason is likely related to stress. In particular, the neurons in which the herpes simplex virus (HSV) reside, are under stress. For the first time, researchers at the University of North Carolina School of Medicine discovered a cellular mechanism that allows the virus to reactivate. They also found how brain cells are duped into allowing bits of virus to escape the very repressive environment in neurons and cause disease. HSV is found in about 90 percent of the...
