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."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
