Speculation that the welfare of a small, at-risk shorebird is directly tied to horseshoe crab populations is in part supported by new scientific research.

Experiments by a team of researchers in New York and New Jersey have generated evidence that questions the common belief that the pterygotid eurypterids ("sea scorpions") were high-level predators in the Paleozoic oceans.

Sensor uses frog peptides to test for drug and medical device contamination.

Having survived for more than 400 million years, the horseshoe crab is now under threat – primarily due to overharvest and habitat destruction.
