Bionanomachines -- proteins as resistance fighters

A Dresden research team used laser tweezers to measure the friction between a single motor protein molecule and its track. The team found that also within our cells, motors work against the resistance of friction and are restrained in its operationâ€"usually by far not as much though as their macroscopic counterparts. These first experimental measurements of protein friction could help researchers to better understand key cellular processes such as cell division which is driven by such molecular machines.

Raising the alarm when DNA goes bad

Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. Scientists have known for a long time that when DNA is damaged, a key enzyme sets off a cellular 'alarm bell' to alert the cell to start the repair process, but until recently little was known about how the cell detects and responds to this alarm. In a study published today in Nature Structural and Molecular Biology, researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have identified a whole family of proteins capable of a direct response to the alarm signal.
