Molecular markers of a mother’s nutrition around the time of conception can be found in her child’s DNA.

People who report having enjoyed amphetamine are more likely to have gene variants associated with protection against attention deficit-hyperactivity disorder and schizophrenia, a study shows.

Shared sequences within the brain lipid-metabolism pathway between Neanderthals and modern Europeans highlight questions about how these genetic similarities arose.

Remarkable findings of ingested plant miRNA in animal liver and blood draw speculation about the study’s validity.

Years ago, tissue samples mounted on glass slides were consigned to a future of histological or immunohistological examination, and then, to the trash bin. Postmicroscopic polymerase chain reaction (PCR) analyses of interesting cellular colonies were impossible, because there was no way to get those cells off the slides, or to isolate those few cells from the vast majority of uninteresting ones. But thanks to laser microdissection (LMD), that is no longer the case. LMD allows researchers to targ

Madison, Wis.-based Promega Corp. has combined a human adult brain cDNA library with the company's TnT® Quick Coupled Transcription/Translation System to help researchers directly correlate proteins with the genes that encode them—without troubling with protein purification and sequencing. All that the researcher needs is an assay for protein activity and Promega's Proteolink™ In Vitro Expression Cloning System. Promega provides 10 96-well master plates containing plasmid-based c
