Robots have been designed to move in ways that mimic animal movements, such as walking and swimming. Scientists are now considering how to design robots that mimic the gliding motion exhibited by flying snakes.
Researchers examine the local communication between endothelial cells and tumors cells and its effects on endothelial cell orientation. The approach uses co-cultured human umbilical vein endothelial cells and breast epithelial tumor cell lines to simulate the tumor-endothelial interaction. The group found the clockwise chirality of the hUVECs was less affected by local hormone signaling and more so by direct physical contact with tumor cells. Specific proteins on the tumor cell binding to others on endothelial cells appeared to play a role in changing the clockwise chirality of hUVECs.
In the Journal of Applied Physics, by AIP Publishing, researchers from the University of Kerala and the University of Nova Gorica, Slovenia developed a method to identify valve dysfunction using a complex network analysis that is accurate, simple to use, and low-cost.
In Journal of Applied Physics, by AIP Publishing, scientists from the University of Cambridge proposed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material.
Washington [US], July 6 (ANI): Scientists revealed a large, all-season ozone hole in the lower stratosphere over the tropics comparable in depth to that of the well-known springtime Antarctic hole, but roughly seven times greater in area. The observed data agree well with the cosmic-ray-driven electron reaction (CRE) model and strongly indicate the identical physical mechanism working for both Antarctic and tropical ozone holes.
