Your Linemen at Work: DNA Search and Rescue Machine Imaged in Action
March 31, 2005
DNA is amazing enough, but its automatic error-correction utilities are enough to stagger the imagination.  There are dozens of repair mechanisms to shield our genetic code from damage; one of them was portrayed in Nature1 March 31 (see also analysis by Sheila David in the same issue2) in terms that should inspire awe.     […]

Descendants Can Overcome Parental Mutations
March 28, 2005
Bad genes from both parents may not spell doom in all cases.  Scientists at Purdue University found that if two parents have bad mutations, the child can sometimes reconstruct the correct gene from the grandparents.  “Our genetic training tells us that’s just not possible,” said Bob Pruitt, co-researcher on the team that ran the experiment […]

How to Get Something from Nothing: Genetic Code, Syntax Explained?
March 23, 2005
Two articles in recent science literature attempt to show that complex entities, like the genetic code and the syntax of human language, are no big deal.  They can emerge from precursors by chance.     In PNAS recently,1 veteran researcher Harold J. Morowitz (George Mason U) and two colleagues proposed a new theory for the […]
