In a world where billions lack clean water, scientists have found a way to pull it from thin air. An international team of ...

Crystal structure analysis reveals Pseudomonas PilY1 as an essential calcium-dependent regulator of bacterial surface motility. Proceedings of the National Academy of Sciences , 2009; DOI: 10.1073 ...

Researchers at the University of North Carolina at Chapel Hill have discovered that a single atom -- a calcium, in fact -- can control how bacteria walk. The finding identifies a key step in the ...

Calcium ions are presented in rocks, bones, shells, biominerals, geological deposits, ocean sediments, and many other important materials. Calcium ions also play major roles in the retention of ...

The calcium-38 nuclei lost a substantial amount of energy in the encounter. The researchers traced the unusual excited levels formed in calcium-38 back to the simultaneous excitation of several ...

By smashing beams of nuclei together at high speeds, researchers have discovered that when a calcium atom has 34 neutrons in its nucleus, things stay pretty quiet—at least for a few milliseconds.

National 4; Atomic structure and properties relating to bonding Compounds. What is an atom? Well, everything is made of atoms! Atoms themselves are made of smaller particles.

The calcium in your bones, like every other heavy atom in your body, was forged in the fiery furnace of enormous stars, 10, 100, even 1000 times the mass of the sun.

The binding and release of a single atom (calcium, shown in light blue) to a bacterial protein is necessary for microbial walking and infection. Credit: Michael D.L. Johnson ...
