PORTLAND, Ore. -- A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop. In a study appearing in today's edition of Nature, John Scott, Ph.D., a Howard Hughes Medical Institute investigator and senior scientist at OHSU's Vollum Institute, found that heart muscle cells become enlarged when an intricate intracellular signaling pathway...

Johns Hopkins scientists have uncovered new details of how smelly things create signals in the nose that eventually go to the brain. The findings raise issues about how the process involved has been described for many years in biology textbooks.The textbooks say that our sense of smell converts odors into brain signals just like our vision converts light into brain signals. But the new work shows that while a key protein pathway is used in both, it behaves quite differently in the nose than...
