Researchers from the National Cancer Institute (NCI) have developed a mouse model of the premature aging syndrome known as Hutchinson-Gilford Progeria Syndrome (HGPS), according to a report appearing in the journal Nature. Researchers hope the mouse model will facilitate a better understanding of the fatal syndrome, as well as provide clues to the normal aging process.
Currently, there is no treatment for progeria, and children with the rare condition usually die of heart disease in their early teens. Although normal at birth, children with progeria begin to develop growth retardation, thinning skin, and fragile bones as young as 18 months.
"The similarities between mice with this particular mutation and patients with progeria are remarkable," said Colin Stewart, Ph.D., of NCIs Center for Cancer Research, the senior investigator on the study. "Now that weve identified the critical gene and have an animal model that mimics progeria, we have powerful tools for studying both the aging process and this devastating disease."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
