(Weizmann Institute of Science) In two complementary studies, Weizmann Institute scientists have developed a new method for reconstructing a cell's 'family tree,' and have applied this technique to trace the history of the development of cancer.

So far, the scientists have been able to calculate the age of the tumor and characterize its growth pattern.

The scientists believe cell lineage studies of cancer can eventually lead us to the root of cancer.

(Weizmann Institute of Science) Weizmann Institute scientist Prof. Naama Barkai and her colleagues have developed a mathematical model to describe interactions that occur within genetic networks of an embryo, answering the age-old question of how half embryos are able to maintain their tissues and organs in the correct proportions despite being smaller than a normal sized embryo.

Understanding the processes that govern embryonic cell development, may lead, in the future, to scientists being able to repair injured tissues.

(Weizmann Institute of Science) Scientists at the Weizmann Institute of Science have shown how quantum systems might disobey a hard and fast rule of physics: While an ensemble of small systems in a larger heat bath should eventually reach thermal equilibrium, repeated measuring of quantum systems could interfere with the process, causing them to heat further or lose energy to the heat bath.

(Weizmann Institute of Science) Scientists from the Weizmann Institute's Materials and Interfaces Department, are developing techniques to coax carbon nanotubes to self-assemble into ordered structures -- essentially making the nanotubes do the hard work for them.

(Weizmann Institute of Science) Scientists at the Weizmann Institute of Science demonstrate that a mathematical concept called recursion can be applied to constructing flawless synthetic DNA molecules.

The ideal molecules are created in successive rounds in which faultless segments are lifted from longer, error-containing DNA strands and assembled anew.
