Can environmental toxins disrupt the biological 'clock'?

Can environmental toxins disrupt circadian rhythms - the biological "clock" whose disturbance is linked to chronic inflammation and a host of human disorders? Research showing a link between circadian disruption and plankton ...

A recording device for cell history

ETH researchers are using the CRISPR-Cas system to develop a novel recording mechanism: The snippets of DNA it produces can provide information about certain cellular processes. In the future, this cellular memory might even ...

Making new functional polymers for 3-D printers

Chemical engineers at the University of Melbourne have found a way to 3-D print smart polymers (or plastics) that can perform a function, in a way that is cheaper, cleaner and more accessible than ever before.
