Forensic proteomics, a new tool for crime labs and anthropology

DNA evidence has revolutionized forensic science in the past few years, cracking open cold cases and bringing both convictions and exonerations. The same techniques help archaeologists and anthropologists studying remains ...

Exhibit A and other true crime shows can fuel misconceptions about forensic science

Forensic science is under attack. A string of recent collapsed trials and quashed convictions that relied on forensic evidence have led some experts to say the field is in crisis.

A combination of agrochemicals shortens the life of bees, study shows

A new study by Brazilian biologists suggests that the effect of pesticides on bees could be worse than previously thought. Even when used at a level considered nonlethal, an insecticide curtailed the lives of bees by up to ...

Cellular microRNA detection with miRacles

MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as ...

Study first to show processes determining fate of new RNA pesticides in soils

A new generation of pesticides can be used to control pest insects by compromising the bug's ability to create essential proteins. These gene-silencing pesticides can be genetically engineered into agricultural crops such ...

Warmer water, chemical exposure influence gene expression across generations in a coastal fish

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species—and threaten ...
