People exposed to high levels of persistent organochlorine pollutants (POPs), which are most likely to come from eating fatty fish such as salmon, might be at risk of developing diabetes.
A study published today in the open access journal Environmental Health reveals that exposure to high levels of POPs, a family of toxic chemicals that includes polychlorinated biphenyls (PCBs) and the insecticide DDT, is associated with a high prevalence of type 2 diabetes mellitus in a population of fishermen and their wives. POPs are by-products of industrial and agricultural processes and are widespread in the environment.
Lars Rylander and colleagues from the University of Lund, Sweden, studied the incidence of type 2 diabetes in196 fishermen and 184 fishermen’s wives, and analysed levels in their blood of the POP residue CB-153, and DDE, the main by-product of DDT. Levels of both residues reflect exposure to POPs.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
