New method for nucleic acid analysis In the world of biomolecules such as proteins and the hereditary nucleic acids DNA and RNA, three-dimensional structure determines function. Analysis of the passage of such molecules through nanopores offers a relatively new, but highly promising, technique for obtaining information about their spatial conformations. However, interactions between the test molecules and the proteins used as pores have so far hindered quantitative analysis of the behavior...

Interactions between proteins are at the heart of cellular processes, and those interactions depend on the interfaces where the direct physical contact occurs. A new study published this week suggests that there may be roughly a thousand structurally-distinct protein-protein interfaces "“ and that their structures depend largely on the simple physics of the proteins. Believed to be the first systematic study of the nature of the protein-protein interfaces, the research could help...

University of Michigan researchers have discovered the rules that dictate the three-dimensional shapes of RNA molecules, rules that are based not on complex chemical interactions but simply on geometry. The work, done by a team led by Hashim M. Al-Hashimi, is described in the Jan. 8, 2010, issue of the journal Science. "RNA is a very floppy molecule that often functions by binding to something else and then radically changing shape," said Al-Hashimi, who is the Robert L. Kuczkowski Professor...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
