Researchers have sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single cell, a long-anticipated step toward better cancer diagnostics and other medical applications.

Researchers have successfully isolated and sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single brain cell. This research, published in the journal Proceedings of the National Academy of Sciences, will help researchers better understand how organs function in health and disease and provide another stepping stone toward personalized medicine.

‘Fat Worms’ Inch Scientists toward Better Biofuel Production

Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves – a feat that could enhance biofuel production as well as lead to improved animal feeds.

The results, published in the current issue of The Plant Cell, the journal of the American Society of Plant Biologists, show that researchers could use an algae gene involved in oil production to engineer a plant that stores lipids or vegetable oil in its leaves – an uncommon occurrence for most plants.

*Plant receptors use different signalling method than do animal receptors*

Every living plant cell and animal cell is surrounded by a membrane. These cellular membranes contain receptor molecules that serve as the cell’s eyes and ears, and help it communicate with other cells and with the outside world.

The receptor molecules accomplish three basic things in the communication process: 1) recognize an outside signal, 2) transport that signal across the cell’s membrane and 3) initiate the reading of the signal inside the cell and then initiate the cell’s response to that signal. These steps are collectively known as transmembrane signaling. (more…)
