The use of pesticides has decreased in the US by more than 40 percent since 1992, but the emergence of more-potent chemicals means that they are far more damaging to many species.

The Scientist Social Club talked to the author and her dad, Chris Miller. 

Overfishing is the biggest factor driving these species toward extinction, researchers conclude from a new study.

Join The Scientist on March 19 to discuss Lulu Miller’s book about a determined taxonomist whose life and work constitute a fable illustrating the hazards of categorization.

In most vertebrates, the absence of adaptive immunity would be catastrophic, but in some deep-sea angler fish species, it enables their “wild” and “wacky” mating habits.

The taxonomist described more than 800 species of fish.

The decades-old signature of nuclear testing can reveal the ages of organisms, or even individual cells.

Rather than making its own light, a shallow-water marine fish gets all the tools that it needs for bioluminescence production from eating tiny, glowing crustaceans.

This 1-centimenter-long frogfish is one of the many subjects of marine photographer Richard Smith.

The Penn State University scientist was known for her work on fish’s perception of pain.

This fish-inspired robot swims at greater speeds than previous ones.

Researchers categorize the different jaws of piscivorous fishes.

The same study also finds there are three species of Electrophorus, rather than one.

The bioluminescent Anomalops katoptron can coordinate its schooling behavior after dark. 

The fish’s undiscerning palate might make more of the lake habitable to the species than once thought, according to a new study.

To see if the spiky fish shares signaling pathways found in other organisms, scientists scooped up specimens during a mating frenzy on the shores of Japan.

Maternal care for the fish alters the structure of their developing heads.

Scientists create a soft-bodied robotic fish that pumps synthetic blood and swims on its own.
