Researchers learn what sparks plant growth

...y clearly that the epidermis is in control—in both driving and restricting growth. In addition, our studies show that the cells in the epidermis "talk" to the cells in the inner layers, communicating that they too should expand." Savaldi-Goldstein made the discovery that the signal for growth originates i...

'Marathon mice' elucidate little-known muscle type

... changed the muscles' metabolic characteristics by driving the activity of genes that spark proliferation of mitochondria. The PGC-1â animals with more IIX muscle fibers showed a greater capacity for aerobic exercise, they found. Transgenic mice were able to run, on average, for 32.5 min to exhaustion, co...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

... warming to unstable international oil supplies is driving a surge in renewable biofuels such as ethanol, with worldwide ethanol production more than doubling between 2000 and 2005. To date, corn has been the favorite ethanol source. While good news for farmers, corn prices have doubled in the past two years...

Killing the messenger RNA -- But which one?

...sion of the microRNA in question had the effect of driving production of the PRPS1 enzyme to about double its normal levels. This, in turn, drove levels of uric acid up to about two times what they should be. "This confirmed that our original computer prediction of differential targeting by unedited and e...
