University of Arizona launches major scientific research initiative at Biosphere 2
...s) at its highest point, it has 6,500 windows that enclose a volume of 7.2 million cubic feet (204,000 cubic meters) under glass. One initial experiment addresses key interactions between plants and water. Within the facility, the researchers will build three hill slopes, each about 32 yards (30 meters) ...Microcapsules like it hot and salty

Then the capsule shell must be sealed to enclose the contents so that they can be released at the location where they are to take effect.

...n the bowls come together, like a shut mouth, they enclose a chamber, shaped like a triangular prism, with a base that measures 35 x 34 x 30 angstroms and a height of 36 angstroms, large enough to contain relatively small peptides, such as insulin or amyloid-beta, which have fewer than 50 amino acids. Al...Researchers map infectious hepatitis B virus
... by a lipid bilayer, similar to the membranes that enclose all human cells. The membrane of hepatitis B virus is studded with glycoprotein spikes, which bind to receptors on liver cells that mediate infection. In hepatitis B-infected liver cells, transcription of the viral DNA produces a type of RNA that is ...Rutgers researchers create tiny chemical cages to enclose drug, pesticide molecules
...avity volume of almost two cubic nanometers, could enclose one or more molecules of a medicine, pesticide or intermediate in a chemical manufacturing process that, if left uncaged, might prematurely decay or interact with other substances in passing. Previous techniques for assembling molecular cages involve...
