Evolution of language: FOXP2 and human uniqueness in religious perspective
...he report by Wolfgang Enard and others expresses a tension found in many kinds of literature, including religion, philosophy, and science.

...subjected to some forms of mechanical load, cyclic tension being one of them," Banes said. "We thought it would be better to grow cells in a dynamic environment, on a flexible substrate. We could then stretch the tissue cells in a certain way to simulate the effects of mechanical loads on tendon, muscle bone...Science editor explores the role of environmental change on global security

Since the lipids and proteins that make up pulmonary surfactant have a very high phosphate content, we surmise that the NaPi-IIb cotransporter is ...UC Berkeley researchers are developing a microsized microscope that can peek inside living cells

The first part of the wave is a tension wave, which stretches the liquid and pulls apart a space for bubbles to form when the liquid is bombarded by energetic particles like neutrons. A second compression wave follows close behind, squeezing and bursting the bubbles, which then emit a bril...New research may lead to more effective treatment of asthmatic attacks
.... When the electrical stress overcomes the surface tension of the liquid, a cone is formed, from which a thin jet emerges. The jet breaks up into monodisperse droplets.

The nozzle and the ring were connected to two high-voltage pow...Nonprofits, corporations can collaborate to improve environmental management

...t because as tethers, only the threads that are in tension can bear the load of a crashing wave. Threads with excess slack are useless. The ability of the threads to stretch allows additional threads to be recruited to hold on. An adult mussel is about 2 inches long.
