Finding explains the development of different forms of the disease
Frequently referred to as a silent killer, ovarian cancer offers few clues to its presence, often until it has spread beyond the ovary to other tissues. Early detection has been difficult because ovarian cancer is not a single disease, but appears in many forms, with each form behaving differently. Now researchers from The University of Texas M. D. Anderson Cancer Center have explained how and why different forms of ovarian cancer evolve in a discovery that could lead to earlier detection and perhaps more personalized treatment for a disease that will claim an estimated 16,210 womens lives in the United States in 2005.
Honami Naora, Ph.D., an assistant professor in M. D. Andersons Department of Molecular Therapeutics and her colleagues discovered that a set of shape-altering genes become activated in ovarian cancer. These HOX genes, better known for their role in normal embryonic development, direct the cancer cells to take a variety of different forms, depending on which of the genes is turned on. The researchers reported their finding in the April 10, 2005 on-line issue of the journal Nature Medicine.

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.

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...
