Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cells ability to detoxify harmful reactive oxygen species. The research appears as the "Paper of the Week" in the November 11 issue of the Journal of Biological Chemistry, an American Society for Biochemistry and Molecular Biology journal.
The klotho gene, named after the Greek goddess who spins lifes thread, is associated with preventing aging in mammals. The klotho gene product, or Klotho protein, is secreted in the blood and functions as an anti-aging hormone. A defect in the klotho gene in mice leads to a syndrome closely resembling human aging, while overexpression of the gene extends lifespan in mice.
Now Makoto Kuro-o, assistant professor of pathology at the University of Texas Southwestern Medical Center at Dallas, has discovered one way in which Klotho extends lifespan. Using both cultured cells and transgenic mice, the researchers showed that Klotho increases resistance to oxidative stress.

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...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
