A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth.

Leading scientists today called for Europe to invest more funds into the study of lipids – the 'fatty' molecules that play a crucial role in the function of human cells and which are implicated in a range of diseases from obesity and diabetes to Alzheimer's.

A team of London scientists have taken a major step in making the use of artificial veins and arteries in coronary bypass grafts a reality. In a study published in the June 2008 print issue of The FASEB Journal, researchers describe how they developed this artificial graft tissue by combining man-made materials with human cells to make it elastic and durable and so it can attach to host tissue.

The number of bacteria living within the body of the average healthy adult human are estimated to outnumber human cells 10 to 1. Changes in these microbial communities may be responsible for digestive disorders, skin diseases, gum disease and even obesity.

Scientists have provided the first large-scale study of proteins inside human cells called Jurkat T cells. The study could provide a better understanding of how proteins inside a specific type of cell work together and may pave the way for future detailed studies of how proteins work in other types of cells.

Human cells function through the concerted action of thousands of proteins that control their growth and differentiation. Yet, the specific function of most human proteins remains either unknown or poorly characterized.

Researchers at Johns Hopkins took advantage of a new technique that reads the makeup of proteins to identify nearly all chemical changes nature makes by adding phosphate to proteins manufactured in human cells.

How is virus as for example HIV and bird flu able to make the cells within a human body work for the purpose of the virus? Researchers at the University of Copenhagen shed new light on this question.
