Scientists at the University of Illinois at Urbana-Champaign have predicted new physics governing compression of water under a high-gradient electric field. Physics Professor Aleksei Aksimentiev and his post doctoral researcher James Wilson found that a high electric field applied to a tiny hole in a graphene membrane would compress the water molecules travelling through the pore by 3 percent. The predicted water compression may eventually prove useful in high-precision filtering of biomolecules for biomedical research.

A new synthetic enzyme, crafted from DNA rather than protein, flips lipid molecules within the cell membrane, triggering a signal pathway that could be harnessed to induce cell death in cancer cells.   

Researchers at University of Illinois at Urbana-Champaign and the University of Cambridge say their lipid-scrambling DNA enzyme is the first in its class to outperform naturally occurring enzymes – and does so by three orders of magnitude. They published their findings in the journal Nature Communications.

In a paper in Nano Letters ("Optical Voltage Sensing Using DNA Origami"), a research team, led by Keyser, Philip Tinnefeld from the Institute of Physical and Theoretical Chemistry at Technical University Braunschweig, and Aleksei Aksimentiev from the University of Illinois at Urbana-Champaign, has now reported for the first time, that a voltage can be read out in a nanopore with a dedicated Förster resonance energy transfer (FRET) sensor on a DNA origami.

Associate Professor Aleksei Aksimentiev and Assistant Professor Shinsei Ryu have each received the 2015 Dean's Award for Excellence in Research from the College of Engineering at the University of Illinois at Urbana Champaign. The two were recognized for their trailblazing research that represents significant contributions to their respective fields. They each received their awards at a College of Engineering faculty awards banquet on Monday, April 27, 2015.
