Water is surprisingly ordered on the nanoscale

26-May-2017

Nanometric-sized water drops are everywhere - in the air as droplets or aerosols, in our bodies as medication, and in the earth, within rocks and oil fields. To understand the behavior of these drops, it is necessary to know how they interact with their hydrophobic environment. This interaction ...

A fresh look inside the protein nano-machines

24-May-2017

Proteins perform vital functions of life, they digest food and fight infections and cancer. They are in fact nano-machines, each one of them designed to perform a specific task. But how did they evolve to match those needs, how did the genes encode the structure and function of proteins? ...

Cracking the code of Huntington's disease

24-Mar-2017

Huntington's disease is a neurodegenerative disorder that causes patients to lose their ability to move, speak, and even think. It is caused by a gene mutation that produces an abnormal form of the protein huntingtin, which aggregates and builds up inside neurons of the cortex and striatum. Small ...
