MIT Biologists Identify Aging Mechanism
...low inbiology at MIT, and Professor Guarente, also communicates the researchers'enthusiasm for the work, with an overtone of wonder at its broad implicationsand precise beauty. "It is remarkable that this mechanism of aging in mother yeast cells isso simple at a molecular level," the biologists wrote. "It...Mathematics Reveals New Pattern Of Brain Cell Activity

A brain cell can talk to its immediateneighbors in what researchers call on-center communicat...Genetically Engineered Mice Exhibit Anxiety, Offering Insight Into Role Of Serotonin In Brain
...sages between brain cells, or neurons. Themolecule communicates its messages through interactions with at least 14distinct types of serotonin receptors, located on the surface of various typesof nerve cells in the brain. In most people, the neural system manages to maintain a normal balance ofserotonin activity...INEEL launches comprehensive vadose zone management program

Those that were unable to makefucose isomerase, the first enzyme in the fucose-metabolizing pathway, couldn'ttell the mice to give them fucose. But mutants that were...Virginia Tech microbe-minerals group launches new field of study

"We know that the earth communicates with water and air, that microorganismsalter the physical and chemical properties of minerals, and that the diversityand distribution of microorganism on earth is at least in part due to thedynamic geochemistry of mineral surfaces," says Hochella.

"This interaction teaches us about how other organisms communicate," Young said. "For example, similar types of communication occurs ...Ras gene causes cancer via different pathways in humans vs. mice
...D., and Joel Elconin, M.D., set out to map how Ras communicates with various signaling pathways that, when over-activated, ultimately command cells to proliferate uncontrollably. The scientists placed human and mouse cells in laboratory dishes, genetically modified the cells to express mutated forms of Ras, then ...UT Southwestern researchers ID key protein for communication within central nervous system
