Gene for acid-sensitive ion channel identified

In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems. Special channels in the cell membrane selectively permit salt ions to flow in and out of cells. A research ...

Ionic thermal up-diffusion boosts energy harvesting

Salinity gradient energy is recognized as a promising candidate for the substitution of traditional fossil fuels. Recently nanofluidic salinity gradient energy harvesting via ion channels or membranes has drawn increasing ...

The pH of calcium ions controls ion channel opening

Ion channels are pores in the membrane of cells or cell organelles. They allow positively or negatively charged particles, so-called ions, to be transported across the membrane. Biochemists at Johannes Gutenberg University ...

Mole rats are pain-free, thanks to evolution

African mole rats are insensitive to many kinds of pain. As an international research team led by the MDC's Gary Lewin reports in Science, this characteristic has allowed mole rats to populate new habitats. Thanks to a genetic ...

Sleep and aging: Two sides of one coin?

Oxford University researchers have discovered a brain process common to sleep and ageing in research that could pave the way for new treatments for insomnia.

The algae's third eye

Scientists at the Universities of W├╝rzburg and Bielefeld in Germany have discovered an unusual new light sensor in green algae. The sensor triggers a reaction that is similar to one in the human eye.
