Sunflowers: Image: Sunflowers
Caption: Agricultural Research Service scientists in Fargo, N.D., may have found the mystery culprit behind unsightly blemishes that began turning up on confection sunflower seeds in 1998.
At first, the prime suspect was a species of disease-causing Alternaria fungus, a common pathogen of sunflower crops. But studies by ARS scientists Thomas Gulya and Laurence Charlet with the agency's Northern Crop Science Laboratory in Fargo exonerated the fungus. When they sprayed sunflower plants with fungicide and then examined the seeds later in the season, many still harbored spots, otherwise known as kernel brown spot. When the plants were sprayed with insecticide, however, the incidence of blemishes dropped sharply
Double Helix: DNA with Features
caption: Cells are the fundamental working units of every living system. All the instructions needed to direct their activities are contained within the chemical DNA (deoxyribonucleic acid).

Jellyfish: Photo: Bioluminescence Aequorea aequorea
Caption: Bioluminescence is a complex chemical reaction within a cell, which releases energy in the form of light. Researchers theorize that this illumination is a form of intra-species and inter-species communication. This natural light show can be seen in a wide variety of marine organisms, such as the Aequorea aequorea, pictured here. The work on the photoprotein aequorin obtained from this jellyfish (Aequorea) was supported by NSF grants from 1960 until July, 2001.
