Obese children who get kidney transplants tend to be younger, shorter and on dialysis longer than their leaner peers, according to a study in the February issue of the journal Pediatrics.
A review of 6,658 children age 2-17 receiving transplants in the United States, Mexico and Canada between 1987 and 2002 showed that obese children age 6-12 had a five-year mortality rate more than double that of non-obese children the same age: 12.1 percent compared to 5.4 percent respectively.
Across the entire age spectrum studied, obese children who received a transplant were more likely to die of cardiopulmonary disease – the leading cause of death in adult kidney transplant patients – than non-obese children. "Pediatricians should educate families on the potential risks of excessive weight gain during dialysis and post-kidney transplant," the authors write, noting that obesity is an increasing problem in patients of all ages with end-stage renal disease and one that has received little attention in children.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
