Protein secrets of Ebola virus
The current Ebola virus outbreak in West Africa, which has claimed more than 2000 lives, has highlighted the need for a deeper understanding of the molecular biology of the virus that could be critical in the development of vaccines or antiviral drugs.

Structure of enzyme seen as target for ALS drugs
Investigators from the University of Texas have determined the first high-resolution structure of an enzyme that, if partially inhibited, could represent a new way to treat most cases of amyotrophic lateral sclerosis (ALS).

New defence mechanism against viruses discovered
Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defence mechanisms against viruses in evolutionary history.

‘Office life’ of bacteria may be their weak spot
Scientists at the University of Leeds think we may be able to drown deadly bacteria in their own paperwork.

Unravelling cell division
Work published in the The Journal of Cell Biology and carried out by a team of researchers from the Centre for Genomic Regulation (CRG) sheds new and revealing light on the complex mechanism of mitosis.

Chemical biologist finds new halogenation enzyme
Molecules containing carbon-halogen bonds are produced naturally across all kingdoms of life and constitute a large family of natural products with a broad range of biological activities.

Measuring modified protein structures
Cells regulate protein functions in a wide variety of ways, including by modifying the protein structure. In an instant, a protein can take on another form and perform no or even the ‘wrong’ function.

Researchers make scientific history with new cellular connection
Researchers led by Dr Helen McNeill at the Lunenfeld-Tanenbaum Research Institute have revealed an unusual biochemical connection that has implications for diseases linked to mitochondria.

Researchers watch lipid molecules in motion
Researchers from Göttingen in collaboration with colleagues from Augsburg have ‘filmed’ the movement of lipid molecules using an X-ray stroboscope at DESY (Deutsches Elektronen-Synchrotron).

Understanding a molecular motor responsible for human development
Another mystery of the human body has been solved by scientists who have identified how a molecular motor essential for human development works. They have also pinpointed why mutations in genes linked to this motor can lead to a range of human diseases.

Single-celled organism smashes and rebuilds its own genome
Life can be so intricate and novel that even a single cell can pack a few surprises, according to a study led by Princeton University researchers.

Targeting the protein-making machinery to stop harmful bacteria
One challenge in killing off harmful bacteria is that many of them develop a resistance to antibiotics.

Study identifies genetic link between the circadian clock and seasonal timing
Researchers from the University of Leicester have for the first time provided experimental evidence for a genetic link between two major timing mechanisms, the circadian clock and the seasonal timer.

Study shows cellular RNA can template DNA repair in yeast
The ability to accurately repair DNA damaged by spontaneous errors, oxidation or mutagens is crucial to the survival of cells.
