University of Rochester scientists studying a vital protein called Serum Response Factor (SRF) in mice have learned new and unexpected facts about SRFs role in early cardiovascular development, and how a defect in this gene may be an underlying cause in human miscarriages.
The research is reported in this weeks Proceedings of the National Academy of Sciences. At this point it is unclear whether subtle defects in SRF might also be linked to adult cardiovascular disease. However, the research provides a foundation for understanding how gene mutations may disrupt heart function, perhaps making some adults more susceptible to heart failure or irregular reactions to drugs.
"One reason for studying the biology of our genetic blueprint is so that we can understand how mutations in the genes encoding for proteins such as SRF may relate to human disease," says Joseph M. Miano, Ph.D., associate professor of Medicine in the Center for Cardiovascular Research at the Universitys Aab Institute of Biomedical Sciences. "Defining the full spectrum of genetic mutations is key to genetic screening and gene-based therapies."

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...
