An emerging species of yeast, Candida parapsilosis is causing increasing numbers of infections because it spreads easily from medical devices into the blood stream of patients. Science Foundation Ireland has recently awarded almost €1 million to Dr. Geraldine Butler of the Conway Institute of Biomolecular and Biomedical Research, Dublin for her pioneering studies of this yeast.
As the yeast grows on the plastic surface of catheters, heart valves or intravenous lines, it forms a thin film called a biofilm, which is difficult to destroy even with antifungal drugs. Infection with yeast can be life threatening in newborn babies, the elderly or any patient whose immune system is not strong enough to fight the bacteria. In many cases, the only treatment choice involves first removing the medical device itself.
Up until now the majority of research has focused on Candida albicans but a recent worldwide study has shown that almost half of all yeast infections are caused by other species of yeast. As the first research group to study C. parapsilosis at a detailed molecular level, Dr. Butler and her team will first try to uncover the genetic makeup of this yeast and then use this information to design in-house genetic techniques to investigate how the yeast grows on the surfaces of medical devices.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
