New Light Shed On A Long-Studied Biological Process
2013-08-08 13:05:11

UC San Diego One of the most basic and intensively studied processes in biology -- one which has been detailed in biology textbooks for decades -- has gained a new level of understanding, thanks to the application of simple math to a problem that scientists never before thought could benefit from mathematics. The scientists who made the discovery, published in this week's advance online publication of Nature, found that the process bacteria use to quickly adapt to metabolize preferred...

Synthetic biology helps scientists sort out pattern formation Many living things have stripes, but the developmental processes that create these and other patterns are complex and difficult to untangle. Now a team of scientists has designed a simple genetic circuit that creates a striped pattern that they can control by tweaking a single gene. "The essential components can be buried in a complex physiological context," said Terence Hwa, a professor of physics at the University of...

Even microbes are governed by the principle of supply and demand "“ at least at the genetic level. Not all of their gene products, the blueprints for proteins, are required at all times. That means most of their genes only become active when they are needed, as is the case in higher organisms. In the simplest case, a transcription factor will activate the gene in question at the right time. Genes that are regulated in a somewhat more complex manner, on the other hand, are kept inactive...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
