Water management is the key to regulating cell volume says Dutch researcher Bas Tomassen. He investigated the uptake and secretion of water by the plasma membrane of animal and human cells.
Cell volume is the outcome of a subtle balance between water uptake and secretion by the cell plasma membrane. A cell can regulate its volume by adjusting the salt concentrations in and around the cell. Exactly how this process works is still not known. Bas Tomassen has identified a number of important mechanisms that play a role in this process.
Increasing the salt concentration in the cell or decreasing the salt concentration around the cell leads to an influx of water. This principle is known as osmosis. Cells activate various channels to remove excess water and salt or osmotically active particles from the cell.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
