The Sweet, Sweet Smell of Diacetyl

Chemosensation in C. elegans Worms have a very simple chemosensory system composed of 32 neurons. Despite this simplicity, they are capable of detecting and appropriately responding to a Dallas, Texas 75235-9111 wide range of chemicals (Bargmann et al. Lucretius, one of the early Greek atomists, suggested have shown that chemoattraction to a number of mole-that all substances having odor gave o...

Sweet solution

Sugar pills are usually placebos, but Smith et al. (2002, this issue) use one to rescue designer mice unable to make GDP-Fucose. Dietary fucose enters a salvage pathway and spares the mice. Sound simple? Not so. Unknown genetic factors determine life or death.

Sweet Successes

Mapping of the chromosomal location of genes essential for sweet and bitter taste and identification of the relevant G protein-coupled receptors reveals unanticipated complexity in taste signaling pathways. The distribution of sweet and bitter receptors suggests complete cellular segregation of these taste modalities. Sweet compounds may be distinguished through differential expression of sweet...

Radio Frequency Heating of Walnuts and Sweet Cherries to Control Insects after Harvest

Radio frequency (RF) heating has been explored as a potential non-chemical method to control insects in harvested walnuts and as a quarantine treatment for ‘Bing’ sweet cherries. Walnuts were heated to 50 to 90°C. Heating walnuts to 55°C or higher resulted in 100% mortality of fifth instar navel orangeworm, and heating to 80°C had no effect on walnut quality. Moisture content had a significant ...
