Scientists may have found a way to keep a protein "watchdog" on high alert to stop hereditary cancers from overrunning our bodies – if they can keep it on a leash of just the right length.
In a collaborative effort, a team of scientists including Purdue Universitys Susan M. Mendrysa has found that one of the proteins found naturally in cells has the ability to halt the progression of intestinal tumors that arise from genetic predisposition. When the activity of this protein, known only by the technical name of p53, was artificially increased in the cells of laboratory mice, those known to have a hereditary predisposition for developing cancer showed a marked decrease in tumor development when compared with mice that had normal p53 activity.
The study also indicated that the treated mice did not suffer from the side effect the research team most feared: premature aging, which has been linked to overproduction of p53 in other studies. The discovery could assist in future human cancer treatments.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
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...

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
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...
