How E. coli bacterium generates simplicity from complexity

... factors are key determinants of how the bacterium organizes itself." Barrett, Palsson, and their colleagues simulated the "functional states" of E. coli's metabolic and transcriptional regulatory networks in the 15,580 environments of food sources and electron acceptors. To their surprise, no matter what car...

UW scientists unravel critical genetic puzzle for flu virus replication

...and inner workings of flu viruses, how the microbe organizes its genetic contents to seed future generations of...us particles to assess how the virus assembles and organizes the strands of RNA that carry its genes so it can exit one cell and go on to infect other cells. Wh...

Scientists discover a genetic code for organizing DNA within the nucleus

...d or caused by mutations in the DNA and the way it organizes into chromosomes. Such mutational processes may be influenced by the relative accessibility of the DNA to various proteins and by the organization of the DNA in the cell nucleus. Therefore, the scientists believe that the nucleosome positioning code ...

A new approach to growing heart muscle

...hat is ready within a few days, that spontaneously organizes and begins to contract with a significant and measurable force, and that responds appropriately to external factors such as calcium." The new paper actually compares two different ways of using fibrin gel as a basis for creating BEHM: layering on ...

Scientists crack genetic secrets of human egg

...anges." Combined with sperm, the egg divides and organizes cells to ultimately create a human being. Combined with technology, the unfertilized egg might be coaxed to produce other specific cells, including stem cells, which can be directed to grow into new tissue. This potential could be used to combat d...

Walking molecule now carries packages

...place calls, nothing else. Now it plays mp3-files, organizes your day, lets you send emails and browse the web." He said his team will be pursuing the next step for this molecule carrier. "Next, we would like to be able to make one go around corners, rotate its cargo or send out photons to tell us where it is....
