Side-by-side comparisons of organic and conventional strawberry farms and their fruit found the organic farms produced more flavorful and nutritious berries while leaving the soil healthier and more genetically diverse. The study is among the most comprehensive of its kind, analyzing 31 chemical and biological soil properties, soil DNA, and the taste, nutrition and quality of three strawberry varieties on more than two dozen commercial fields -- 13 conventional and 13 organic.

A long-held assumption about asymmetrical division of stem cells has cracked. Researchers report that the mitotic spindle does not act alone -- that cortical proteins help to position a cleavage furrow in the right location.

Researchers have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signaling molecules between organisms.

Scientists have demonstrated the synthesis of nanosize biological particles with the potential to fight cancer and other illnesses. The research introduces new approaches that are considered "green" nanobiotechnology because they use no artificial compounds.

Lima beans were domesticated at least twice, according to a new genetic diversity study. Big seeded varieties known as "Big Lima" were domesticated in the Andean Mountains, while small seeded "Sieva" and "Potato" varieties originated in central-western Mexico.

Subfertility of breeding stallions -- meaning the horses are less able to sire foals -- is a well-recognized problem that has caused multi-million-dollar losses in the equine industry, experts say. Researchers believe they are making progress in solving the problem by using an approach that might provide tools and resources necessary to study subfertility without causing stallions the angst of providing testicular samples for testing.

A new study finds that exposure of pregnant female mice to the endocrine-disrupting chemical bisphenol A may produce adverse reproductive consequences on gene expression in fetal ovaries as early as 12 hours after the mother has first been exposed to the chemical.

A Norwegian company has developed a new genetic test that quickly determines which salmon have the highest resistance to the IPN virus. The recently launched commercial product could mean a breakthrough in the battle against this costly disease.

After more than a decade of research, scientists have pieced together the structure of a human adenovirus -- the largest complex ever determined at atomic resolution.

For the first time ever, a completely artificial chemical enzyme has been successfully used to neutralize a toxin found naturally in fruits and vegetables. This is the first evidence that it's possible to design artificial enzymes for this class of task, and might result in a completely new way of designing drug-targets.
