Early surgical removal of the spleen combined with antiangiogenic cancer therapy may halt the progression of leukemia, according to scientists at Sunnybrook and Women’s College Health Sciences Centre.
The research, published today in Blood, is the first to show the combination of two factors secreted from the environment of the spleen is important in the promotion of leukemia.
Dr. Yaacov Ben-David, a Senior Scientist in Molecular and Cellular Biology at the Sunnybrook & Women’s Research Institute who is the lead investigator in the study and colleagues, including Dr. Yuval Shaked, a post-doctoral fellow, discovered that the spleen of diseased mice provides a supportive environment for cancer cells. The spleen secretes various factors, among them MCP and VEGF, which relate to the immune system and promote formation of new blood vessels. Secretions of these factors cause leukemic cells in the spleen to multiply. In this study, Dr. Ben-David’s team showed that these factors might contribute to the progression of breast and other types of cancer.

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...
