As concerns rise about the ecological impacts of genetically modified crops, a new Indiana University study urges a pragmatic approach to dealing with "transgenes" that escape from crop plants into the wild. Use of transgenic crops is becoming more common as farmers reap benefits from the plants decreased susceptibility to disease and increased marketplace value.
IU biologist Loren Rieseberg and former postdoctoral fellow John Burke (now at Vanderbilt University) reported in the May 23 issue of Science that a wheat transgene synthetically inserted into sunflowers has little or no effect on crop sunflowers wild relatives and is not likely to impact the environment.
"We found that a certain transgene that gives crop sunflowers resistance to white mold is unlikely to spread rapidly to the wild because the transgene doesnt affect the seed-producing abilities of wild sunflowers in nature," said Rieseberg, who led the study. "We need to examine each transgene and crop on a case-by-case basis. Some transgenes will have major ecological impacts and others probably wont."

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
