New technology for bioseparation

Separating target molecules in biological samples is a critical part of diagnosing and detecting diseases. Usually the target and probe molecules are mixed and then separated in batch processes that require multiple pipetting, ...

Cells use water in nano-rotors to power energy conversion

Researchers from the Max Planck Institute of Biophysics in Frankfurt, and Mount Sinai School of Medicine in New York have provided the first atomic-level glimpse of the proton-driven motor from a major group of ATP synthases, ...

The light of fireflies for medical diagnostics

In biology and medicine, we often need to detect biological molecules. For example, in cancer diagnostics, doctors need quick and reliable ways of knowing if tumor cells are present in the patient's body. Although such detection ...

A kiss of death to drug the 'undruggable'

Scientists at the University of Dundee have reported a major breakthrough in targeting the causes of many diseases, using a `kiss of death' to destroy proteins which had previously been regarded as 'undruggable'.

Researchers find new way to target flu virus

There's a hitch in the swing of a protein that delivers the flu virus. Rice University and Baylor College of Medicine researchers believe this mechanism may be a useful target to stop the virus from infecting cells.
