A typically innocuous virus found in 90 percent of people worldwide is the key to a new treatment for a cancer particularly common in North Africa and Southeast Asia. A new study showing that antigens produced by the Epstein Barr virus may provide an ideal target for therapy will be published in the March 1, 2005, issue of Blood, the official journal of the American Society of Hematology.
Ten patients diagnosed with advanced nasopharyngeal carcinoma took part in the study – these patients also tested positive for the Epstein Barr virus, a member of the herpes family responsible for the "kissing disease" (mononucleosis) and commonly associated with this cancers tumors.
Patients were given intravenous doses of specialized T cells that specifically targeted antigens produced by the Epstein Barr virus. Developed by researchers from the Center for Cell and Gene Therapy at Baylor College of Medicine, Methodist Hospital in Houston, and Texas Childrens Hospital, these T cells were created using the patients own blood to recognize the antigens and destroy the cancerous cells harboring the virus. The treatment was well tolerated in all but one patient, who had pre-existing facial swelling that increased after the infusion.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

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...
