Scientists uncover mysterious workings of cholera bacteria

Researchers have found that an enzyme in the bacteria that causes cholera uses a previously unknown mechanism in providing the bacteria with energy. Because the enzyme is not found in most other organisms, including humans, ...

New role for the JNK protein

Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle - the cell's process of duplicating itself to make more cells - goes smoothly, a large network of proteins tells other proteins ...

Intercellular communication: From 'cable-phone' to 'cell-phone'?

Secreted microRNAs (miRNAs) from cells to blood maybe the novel class of signaling molecules mediating intercellular/interorgan communication. A research article, published this week in Molecular Cell, reports that miRNA ...

Cell signaling classification system gives researchers new tool

Using ever-growing genome data, scientists with the Department of Energy's (DOE) Oak Ridge National Laboratory and the University of Tennessee are tracing the evolution of the bacterial regulatory system that controls cellular ...

Biochemists take a bead on gene-controlling code

(PhysOrg.com) -- DNA may provide the blueprint for life, but scientists are learning more about the role of a chemical code that governs the way that blueprint is read.

Biology May Not Be So Complex Afterall

(PhysOrg.com) -- Centuries ago, scientists began reducing the physics of the universe into a few, key laws described by a handful of parameters. Such simple descriptions have remained elusive for complex biological systems ...
