For nearly a decade, scientists have known that leptin plays an important fat-burning role in humans. But the map of leptins path through the body – the key to understanding how and why the hormone works – is still incomplete.
Now a small but critical section of that map is charted, based on new research conducted at Brown Medical School and Rhode Island Hospital and at Harvard Medical School and Beth Israel Deaconess Medical Center.
The research team found that leptin triggers production of the active form of a peptide – áMSH – in the hypothalamus, the small area in the base of the brain that controls hunger and metabolism. Researchers say this peptide, or small protein, is one of the bodys most powerful metabolism booster signals, sending a fast, strong message to the brain to burn calories.

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...
