A Purdue University research team has found a set of genes that may orchestrate insects ability to fight the effects of pesticides.
Tiny fruit flies are the subjects of Purdue University entomology researcher Barry Pittendrighs efforts to discover how insects neutralize the pesticides designed to kill them. He believes that a series of genes are players that orchestrate the biochemical processes involved in pesticide resistance. His study was published in the current issue of Proceedings of the National Academy of Sciences. (Purdue Agricultural Communication photo/Tom Campbell)
"Our study suggests that more than one gene may be involved in making insects resistant to certain pesticides," said Barry Pittendrigh, associate professor of entomology. "Using a music analogy, metabolic resistance may not be a single individual playing a single instrument. Its more likely a symphony with numerous instruments playing a role in producing the music."
The ultimate aim of the research is to develop methods to prevent insect damage to plants, he said. Results of the initial study are published in the Tuesday (May 4) issue of Proceedings of the National Academy of Sciences.

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...
