In the study, Liman and Liu looked closely at a protein necessary for detecting sweet, bitter and umami tastes. Without the protein, called TRPM5, mice can't discern between the flavors. Once activated, the protein appears to play a key role in the taste-signaling pathway, somehow sending...'Homegrown' relief for victims of arsenic poisoning in South Asia
