Scientists glean new insight from prematurely old mice
The relationship between genome integrity and aging is the subject of a new report in the upcoming issue of Genes & Development. Drs Lin-Quan Sun and Robert Arceci at Johns Hopkins University School of Medicine have developed a novel mouse model to study premature aging, and the genetic events that contribute to normal development and longevity.
"The inability of an organism to maintain the integrity of its genome has been postulated to be an important cause of aging, developmental abnormalities and predisposition to cancer," explains Dr. Arceci, corresponding author and professor of pediatrics and oncology at The Johns Hopkins Kimmel Cancer Center.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
