The tiniest structures in cells can be seen only using sophisticated instrumentation and informatics, but what biologists really need are improved fluorescent probes.
Monitoring technologies and genetic engineering are producing a growing array of animal models for psychiatric disorders, but researchers are still learning how best to use them.
Biologists have copied an existing genetic code, but haven't yet commercialized it or written their own. What will it take for a tour de force to reach industrial force?
For years, scientists have struggled to reconstruct tissues and organs by combining cells and nanotechnology. These devices are now edging from cool concept to practical application.
