Researchers at the European Molecular Biology Laboratory (EMBL) and the University of Rome "La Sapienza" have found a way to restore some of the "regenerative" ability of tissues, which happens naturally in animals at the embryonic stage of development, but is lost shortly after birth. The scientists work, published this week in PNAS, gives new insight into how stem cells can be mobilized across the body, and how they take on specialized functions in tissue.
"Many labs have reported the integration of stem cells into various types of tissues, but on a small scale," says Prof. Nadia Rosenthal, Coordinator of EMBLs Mouse Programme in Monterotondo, Italy. "This is the first study to show that stem cells can be mobilized to achieve a major regeneration of damaged tissue."
In a collaboration with the group of Antonio Musarò at the University of Rome, the scientists investigated muscle tissue in mice, discovering that stem cells can travel large distances to reach an injury. They also found a special form of a protein called mIGF-1 induces the muscle to send the distress signal that summons them.

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...
