Heme is key to proteins work
University of Toronto researchers have gained new insight into how a specific protein may control circadian rhythms and metabolic processes, which has implications for treating cholesterol-related diseases.
U of T professor Henry Krause and his colleagues have identified heme, an iron compound, best known for its oxygen carrying capabilities in hemoglobin, as the molecule that allows the protein E75 to regulate a number of key developmental processes. In a paper published in the July 29 issue of Cell, the researchers use fruit flies to show that heme attaches itself to E75, allowing the protein to respond to a variety of cellular signals necessary for controlling systemic processes such as metabolism and circadian rhythms, the human bodys clock.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
