The 'weakest link' in the aging proteome

Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are ...

Tissue in trouble calls in reinforcements to restore health

Northwestern University scientists are the first to discover a cellular process used by animals when a tissue is stressed and in molecular trouble from the expression of misfolded and damaged proteins: The tissue at risk ...

Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

Trifunctional molecule decodes cellular communication

(Phys.org)—How does one define the factors on the surface of human cells to which a molecule of interest binds? This question is typically hard to answer. Researchers of ETH Zurich have developed a new technology that enables ...

Technology convergence may widen the digital divide

(Phys.org) -- Technology is helping communication companies merge telephone, television and Internet services, but a push to deregulate may leave some customers on the wrong side of the digital divide during this convergence, ...

Researchers present a shiny new tool for imaging biomolecules

At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals that can mean life ...
