How does a cell maintain its identity during replication? Long-held view of cell division overturned

How does a cell maintain its identity during replication? Long-held view of cell division overturned | FOCUS: Investigations in Contemporary Science | Scoop.it
Prior to cell division, chromosomes are seemingly a jumbled mess. During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming thousands of times more compact than at any other time. Researchers have long assumed that genes become "silent" during cell division, not being transcribed into proteins or regulatory molecules. This has left open the question of how genes get properly re-activated after cell division. Now, researchers have found that gene expression actually continues during cell replication.

The way airlines board planes affects how easily bugs are spread among passengers | FOCUS: Investigations in Contemporary Science | Scoop.it
IT IS an often-heard office conversation. Someone returns from a trip with a nasty bug, and colleagues say he must have caught it from a germ-ridden plane. It is not unusual to come down with something nasty after flying. And as a fellow Gulliver reported last week, contaminated air on flights is widespread.
