Vessel wall cells and blood cells have been found to release cell particles which can damage blood vessels. This was demonstrated in laboratory experiments carried out by Marja van Wijk during her doctoral research at the University of Amsterdam. Poorly functioning blood vessels play a role in pre-eclampsia.
For her research (conducted at the Academic Medical Centre, University of Amsterdam) Van Wijk isolated blood vessels from pieces of tissue taken from pregnant women. She placed the blood vessels in a solution of microparticles isolated from the blood of pregnant women with and without pre-eclampsia. A so-called wire myograph was then used to measure the functioning of the blood vessels.
Vessels in a solution of affected microparticles were found to function less well than vessels with healthy particles. Which microparticles or parts thereof are responsible for the vessel damage is not clear. Exactly how the particles are formed must also be investigated.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
