Researchers at the McGill University Health Centre (MUHC), in Montreal, have identified a new gene to combat cancer. In a new study, published in the on-line edition of the journal Clinical Cancer Research this week, the researchers document a reduction in the growth of both colon and lung cancer tumors with inhibition of the gene.
The new target gene is called methylenetetrahydrofolate reductase, or MTHFR. Researchers were able to inhibit the function of the gene by creating antisense-an exact opposite of a tiny section of the MTHFR gene. "MTHFR is involved in the synthesis of methionine-a critical nutrient necessary for growth of cancer cells," explains Dr. Rima Rozen, principal investigator of the new study, and Deputy Scientific Director of the MUHC Research Institute. "By inhibiting the gene’s function, we were able to slow the growth of tumors."
Researchers found that the antisense reduced lung and colon cancer tumors in both laboratory-based tissue cultures and in mice. "Discovering that the antisense works in animal models is a major step forward, and gives us hope that this might also work in humans," explains Dr. Rozen.

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.

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...
