In evolution, 'house of cards' model wins

Using sophisticated modeling of genomic data from diverse species, Yale researchers have answered a longstanding question about which competing model of evolution works best.

Scientists find DNA is packaged like a yoyo

To pack two meters of DNA into a microscopic cell, the string of genetic information must be wound extremely carefully into chromosomes. Surprisingly the DNA's sequence causes it to be coiled and uncoiled much like a yoyo, ...

Aggressive plant fungus threatens wheat production

The spread of exotic and aggressive strains of a plant fungus is presenting a serious threat to wheat production in the UK, according to research published in Genome Biology. The research uses a new surveillance technique ...

Cell biologists discover on-off switch for key stem cell gene

Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it must wait. The same ...

James Watson's Nobel Prize to be auctioned

Missed the chance to bid on Francis Crick's Nobel Prize when it was auctioned off last year for $2.27 million? No worries, you'll have another chance to own a piece of science history on Dec. 4, when James D. Watson's 1962 ...

Bacteria become 'genomic tape recorders'

MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such ...
