Researchers seek deeper understanding of how cells operate

Cells sense and respond to the mechanical properties of the cellular microenvironment in the body. Changes in these properties, which occur in a number of human pathologies, including cancer, can elicit abnormal responses ...

Researchers discover a new method to regulate cell plasticity

Cell plasticity is a property by which a cell can take on different and reversible identities. Cell plasticity is also essential for embryo development and for the correct function of the immune system. This property is also ...

Cell stiffness may indicate whether tumors will invade

Engineers at MIT and elsewhere have tracked the evolution of individual cells within an initially benign tumor, showing how the physical properties of those cells drive the tumor to become invasive, or metastatic.

Antireflection coating makes plastic invisible

Antireflection (AR) coatings on plastics have a multitude of practical applications, including glare reduction on eyeglasses, computer monitors and the display on your smart-phone when outdoors. Now, researchers at Penn State ...

Virtually modelling the human brain in a computer

Neurons that remain active even after the triggering stimulus has been silenced form the basis of short-term memory. The brain uses rhythmically active neurons to combine larger groups of neurons into functional units. Until ...

New model for the origin of grid cells

Ludwig Maximilian University of Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals ...

X-ray vision reveals how polymer solar cells wear out

Scientists from the Technical University of Munich have used the acurate X-ray vision provided by DESY's radiation source PETRA III to observe the degradation of plastic solar cells. Their study suggests an approach for improving ...
