Two studies by researchers at the University of Chicago show how the bacteria that cause the plague manage to outsmart the immune system and how, by slightly altering one of the microbes tools, the researchers produced what may be the first safe and effective vaccine.
Both papers -- one published online July 28 in Science Express and one in the August issue of Infection and Immunity -- focus on aspects of the type-III pathway, a molecular syringe that Yersinia pestis, the bacterium that may have killed more people throughout history than any other infectious disease, uses to disable its hosts immune system.
"Yersinia pestis is the nastiest thing alive," said study author Olaf Schneewind, M.D., Ph.D., professor and chairman of microbiology at the University of Chicago and director of the Great Lakes Regional Center of Excellence in Biodefense and Emerging Infectious Diseases Research (GLRCE). "Its the most virulent bacterial organism known to mankind. But we now know a little more about how it exercises those powers and we think we can use that knowledge to prepare a preemptive strike."

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...
