Liverpool amongst first in UK to install unique DNA sequencing technology

Unique technology, that uses the enzymes of fireflies to read the genetic code of DNA, has been installed at the University of Liverpool.

Liverpool is one of only two universities in the UK with the machine, which can read up to 100 million DNA letters in a few hours compared to technology currently in use that can only process 50,000.

The machine - called GS-Flex - is unique in that it uses an enzyme found in fireflies as a flash light to help read the DNA strand.

Scientists from all over the UK will be able to use the new technology for a variety of different purposes, from cancer research to veterinary science. Researchers at Liverpool, for example are looking at DNA sequencing of the malaria parasite. By studying changes in parasite DNA scientists aim to understand why some species of malaria can infect humans and others can only infect other animals.

Professor Neil Hall, at the University’s School of Biological Sciences, explains: “This new machine is invaluable not only for research into diseases such as cancer and malaria, but for our understanding of genetics as a whole. For example we have scientists looking at the DNA of fish in understanding how genes are activated and we have veterinary scientists looking at how illnesses in domestic pets can be passed to humans.

“We have a team of experts at the University that are skilled in using this technology and we are therefore in a position to welcome collaboration with other institutions in reaping the benefits of this.”

Current DNA sequencing has been pioneered by institutes like the Wellcome Trust’s Sanger Institute. It was here that scientists decoded a record-breaking two billion letters of DNA in the human genome. In order to do this, however the technology which was large and complex required hundred of machines housed in specially constructed buildings. The new state-of-the-art machine is now no bigger than a photocopier and stored in a laboratory at the University’s School of Biological Sciences.

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...
