Plasmodium falciparum, the most lethal malaria parasite, is a housebreaking villain of the red blood cell world. Like a burglar searching for a way in to his targeted premises, the parasite explores a variety of potential entry points to invade the red blood cells of its human victims. When a weak point is found, the intrusion proceeds.
Scientists have known about the parasites housebreaking habit for a decade, but just how it breaks in to blood cells has been unknown.
Now, an international team of scientists, led by WEHIs Professor Alan Cowman, has discovered the gene - known as PfRh4 - that the parasite uses as a tool to switch between potential invasion points. More specifically, the gene provides the parasite with the ability to switch from receptors on red blood cells that contain sialic acid to those that do not.

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...
