New technologies advance livestock genomics for agricultural and biomedical uses

New genome editing technologies developed at the University of Minnesota for use on livestock will allow scientists to learn more about human diseases.

The genomic technique, known as TALENS, is described in a report published today in the scientific journal Proceedings of the National Academy of Science. The technique is cheaper and faster than previous technologies that allow scientists to genetically modify livestock animals; the animals are used to learn more about human diseases, which in turn can help researchers develop cures. U of M scientists and their collaborators used the technique to develop a swine model of cardiovascular disease in the diabetes-prone Ossabaw miniature pig.

The TALENS technique also can be used in agriculture, the paper notes, allowing livestock breeders to encourage or discourage a particular trait. 

“Our efforts continue a long tradition of responsible animal breeding and research for the betterment of mankind,” said Scott Fahrenkrug, an associate professor of animal science at the university and lead author of the PNAS paper. 

Collaborators on the paper are from Texas A&M, the Roslin Institute at the University of Edinburgh and Recombinetics, a Twin Cities-based company created in 2009 to commercialize the techniques created at the University of Minnesota. The group’s work and the TALENS technique also recently were highlighted in the journal Nature. 

“This work embodies the effective translation of university research into meaningful applications that support Minnesota business,” Fahrenkrug said. “We are proud to produce positive social and economic outcomes.”

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'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...
