Bone proteomics could reveal how long a corpse has been underwater
When a dead body is found, one of the first things a forensic pathologist tries to do is estimate the time of death. There are several ways to do this, including measuring body temperature or observing insect activity, but these…
Long-term consequences of coastal development as bad as an oil spill on coral reefs
The near-shore habitats of Bahia Las Minas in the central Caribbean coast of Panama became heavily contaminated after a refinery accident in 1986. Over the next five years, there was a significant decline in the numbers and diversity of corals.…
