The origins of a genetic switch

Cilia, microscopic whip-like organelles that protrude from the surface of many cell types, are almost ubiquitous. They are present in all eukaryotes—organisms whose cells have a nucleus—and have diversified to perform ...

Biologists identify proteins vital to chromosome segregation

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome ...

It pays to cooperate

Many species exhibit cooperative survival strategies—for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage ...

New type of bacterial protection found within cells

UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections.

Viable and fertile fruit flies in the absence of histone H3.3

Histones—proteins that package DNA—affect cell function differently than previously assumed: the cell doesn't need the histone H3.3 to read genes. Molecular biologists from the University of Zurich demonstrate that fruit ...

US computer graphics scientist wins Kyoto Prize
