The bacterium that causes the severe disease known as rabbit fever, Fancisella tularensis, is a potential biological weapon of devastating force. Now scientists at Umeå, in collaboration with several international associates, have mapped the entire genome of the bacterium.
Researchers at the Swedish Defense Research Agency FOI NBC Defense and Umeå University are part of an international consortium that is now publishing its results in the prestigious journal Nature Genetics. The article is a report from the charting of the complete DNA sequence of the bacterium, so-called sequencing, and the study of the genome of a fully pathogenic strain of Francisella tularensis. The genome consists of nearly 1.9 billion base pairs, among which the scientists have managed to find 1,804 genes.
The functional description of the genome presents the pathogenic properties of the bacterium, including the formation of so-called pili, a type of projection that is used in infecting human cells. Another property described is the ability of the bacterium to absorb iron, a feature that is necessary for the bacterium to be able to bring about disease.

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...
