Humans and fruitflies - those pesky little buggers that are irresistibly attracted to overripe fruit - share more than a sweet tooth. Both rely on the same insulin-regulated molecular pathway to maintain their energy balance when starved for food
...> Full Article
 | A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster ...> Full Article |
Researchers have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.
...> Full Article
Clues into how preeclampsia may surface in some pregnancies
...> Full Article
By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.

 | If this technology is adopted by producers, in theory, we should never see another case of this form of dwarfism. ...> Full Article |
Scientists have produced the first complete description of the complex network of genes that create a particular type of cell in an organism.
...> Full Article
Retinas in newborn mice appear perfectly fine without any help from tiny bits of genetic material called microRNAs except for one thing - the retinas do not work.
...> Full Article
 | The secret to an unusually large bacteria may be found in its ability to copy its genome tens of thousands of times. ...> Full Article |
 | The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. ...> Full Article |
