New complete muscle grown in the lab

...n two weeks. The endothelial cells and the vessel networks that they provide may also be useful in coaxing the muscle cells to differentiate and organize themselves in a mature, three-dimensional tissue, the researchers suggest. To test the new muscles' therapeutic potential, the researchers implanted them ...

Computational Tool Predicts How Drugs Work In Cells, Advancing Efforts To Design Better Medicines

...g approach to decipher the multitude of regulatory networks operating among genes in a simple organism, then testing the ability of the resulting network models to predict gene and pathway targets for a variety of drug treatments. Finally, they used the tool to predict the molecular targets of a potential new...

Microarrays as phenotype

...enes interact as well as how they are regulated by networks within the cell. They are created by the placement of tiny droplets of functional DNA on glass slides. Then researchers attach fluorescent labels to nucleic acids (DNA or RNA) from the cells under study. These labeled nucleic acids are allowed to bin...

New research published in the Open Access journal Journal of Biology shows that such maps can also reveal cryptic interactions and enable accurate predictions about interactions that...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

... a connection between romantic love and motivation networks in the brain. "As it turns out, romantic love is probably best characterized as a motivation or goal-oriented state that leads to various specific emotions, such as euphoria or anxiety," Aron noted. "With this view, it becomes clearer why the lover ...

Researchers find new genes necessary to make embryo

...ment. The new findings also probe into how genetic networks are built and how they could evolve. The team, headed by biologists at NYU, is studying the genome of the Caenorhabditis elegans (C. elegans), the first animal species whose genome was completely sequenced and a model organism to study how embryos d...

Transporter molecules are the proteins that retrieve neurotransmitter molecules from the spaces between neurons after they trigger nerve impulse, to reload the neuron for its next signaling...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits
