Potatoes with higher levels of beneficial carotenoids are the result of U.S. Department of Agriculture (USDA) studies to improve one of America's most popular vegetables.

Protein-labeling technique allows high-resolution visualization of molecules inside cells.

Strong growth in healthcare spending, especially in emerging economies, is driving increased demand for medical testing, drug discovery, genomics, and proteomics, as well as the instruments used to carry out these processes.

Problem: A mainstay in life science research, western blotting is commonly used to assess relative protein expression differences, such as when investigating cellular signaling pathways. Accurate quantification requires careful attention to procedural details and normalization.

Electrophoresis relies on a basic process— particles moving in an electric field, more or less. Although known for more than 200 years, this phenomenon still drives fundamental techniques in many laboratories.

Many branches of molecular bioscience offer the prospect of greater precision in medical care, but some clinical tests based on "omics" research have proved invalid and highlighted the challenges of dealing with complex data.
