radioactive isotopes

A mass death event claimed the hominins’ lives and likely resulted from changing environmental conditions.

Forensic scientists have been using rudimentary molecular techniques for decades. But advanced forensic anthropology technologies and
methods are just now coming to the fore in some investigations.

Some thoughts about the ecological fallout from Fukushima

Scientists find radioactive elements 600 kilometers from Fukushima—but levels are not harmful to human health.

A new analysis suggests that more radioactive contaminants were released from the crippled nuclear power plant then accounted for in official Japanese estimates.

Hair-like extensions on microbes that remove uranium and other metals from contaminated groundwater could one day help clean up after radiation spills.

Scientists take to the seas to study the effects of Fukushima radiation on local marine life.
