Finding the best materials for tomorrow s electronics is the goal of Professor Emanuele Orgiu of the Institut national de la recherche scientifique (INRS). Among the materials in which Professor Orgiu is interested, some are made of molecules that can conduct electricity. He has demonstrated the role played by molecular vibrations on electron conductivity on crystals of such materials. This finding is important for applications of these molecular materials in electronics, energy and information storage. The study, conducted in collaboration with a team from the INRS and the University of Strasbourg (France), was published in the prestigious

Zakya H. Kafafi, Distinguished Research Fellow within the P.C. Rossin College of Engineering and Applied Science at Lehigh University, was recently elected to the National Academy of Engineering (NAE), one of the highest honors given to engineers in the United States.
The NAE provides guidance to the federal government and conducts independent studies in engineering while honoring individuals who have made significant contributions to research, practice, and education, and who have been influential in new fields of technology.
Whispering-gallery-mode (WGM) microresonators are opening up many new research directions that require the detection of proteins, enzymes and DNA, down to single molecules. A new class of sensors makes use of active microresonators to drastically expand the functionality and range of WGM sensor applications, especially for biological and chemical assays.
We review the most recent advances of WGM microlasers for biosensing and provide an outlook on exciting new research directions and emerging WGM sensor applications.

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has developed a device that can deliver electrical signals to and from plants, opening the door to new technologies that make use of plants.
The NTU team developed their plant communication device by attaching a conformable electrode (a piece of conductive material) on the surface of a Venus flytrap plant using a soft and sticky adhesive known as hydrogel. With the electrode attached to the surface of the flytrap, researchers can achieve two things: pick up electrical signals to monitor how the plant responds to its environment, and transmit electrical signals to the plant, to cause it to close its leaves.

WASHINGTON Researchers have developed a new intravascular imaging technique that could one day be used to detect coronary plaques that are likely to lead to a heart attack. Heart attacks are often triggered when an unstable plaque ruptures and then blocks a major artery that carries blood and oxygen to the heart. If unstable coronary plaques could be detected before they rupture, pharmacological or other treatments could be initiated early to prevent heart attacks and save lives, said research team leader Seemantini Nadkarni from the Wellman Center for Photomedicine at Massachusetts General Hospital. Our new imaging technique represents a major step toward achieving this.
