They were not surprised that most of the genes that were turned on fell into the group responsible for the cell signaling processes, Borrs said. But unexpectedly, the genes switched on included two known from previous ...Carnegie Mellon researchers to demonstrate autonomous robotthat will seek life in Atacama Desert

This light sensing system guides seedlings through the soil and has profound influences on their development during the critical stage of seedling establishment and later as the leaves adapt to changes in the light environment.

... like a dinner bell. As Bargmann explains, "Oxygen sensing may be a hunting strategy, like smelling your food, except that in the case of C. elegans it's actually smelling the activity of the food. Since bacteria are incredible oxygen hogs, the food is consuming oxygen faster than oxygen can diffuse." Marlet...ORNL nanoprobe creates world of new possibilities

..., and pursuit of the answer led directly to oxygen sensing in worms. The discovery of a similar enzyme in the nematode, but one that binds oxygen instead of NO, will help Marletta and his colleagues discover the tricks used by the enzyme to let in or screen out oxygen from the heme binding site to selectivel...Protein controls acid in cells by direct detection of volume changes, study finds
