New studies by an international team of scientists led by Joslin Diabetes Center have found variations in a gene that help explain why people with type 2 diabetes are at much greater risk for coronary artery disease, the leading cause of death for this group.
"We now have potential gene markers to help identify diabetes patients at increased risk for heart disease," said Alessandro Doria, M.D., Ph.D., Investigator in Joslins Genetics and Epidemiology research section, Director of Joslins Genetics Core and Assistant Professor of Medicine at Harvard Medical School. "This knowledge could potentially lead to drugs or other methods that affect this pathway, reducing risk of heart attack and stroke in these patients."
An estimated 18 million people in the United States have type 2 diabetes. People with diabetes are two to four times more likely to have cardiovascular disease, and are at increased risk for stroke, blindness, kidney disease and nerve damage.
In a two-part study published in the Oct. 1 edition of the British journal Human Molecular Genetics, Dr. Doria and his colleagues at Joslin and other research centers in the Northeast and researchers in Italy focused on a gene governing a protein called CD36. This protein is found in the membrane of several types of cells, including the walls of blood vessels.

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...
