A long-lost Bolivian killifish has been found alive, revealing a globally important hotspot for seasonal killifish diversity at risk from deforestation. Researchers have confirmed the rediscovery of ...

A Bolivian killifish believed extinct, Moema claudiae, resurfaced in one vulnerable pond, revealing both a conservation win ...

Sarcopenia, the decline in muscle function that comes with age, is poorly understood. Now new research uses a new animal model—the African killifish—to reveal that muscles actually reverse to an ...

The secret to humans thriving well into old age may lie with a species that barely lives for any time at all: the East African turquoise killifish, whose four- to six-month lifespan makes it among the ...

The study also found that six other seasonal killifish species also exist in the same habitat, making the region the most ...

The population of Gulf killifish in the Houston Ship Channel had been steadily declining for decades, likely a result of the toxins pouring in from industrial activity, when suddenly and mysteriously, ...

It's well known that genetic differences among individuals influence lifespan, but a new study suggests that differences in patterns of gene expression in youth may also predict longevity. Researchers ...

Fish in a major shipping port have managed to breed a rare hybrid species to survive its heavily-polluted waters. The Houston Ship Channel in Texas has long posed a major challenge to fish living in ...

Studying aging and its associated diseases has been challenging because existing vertebrate models (e.g., mice) are relatively long lived, while short-lived invertebrate species (e.g., yeast and worms ...

How long can you hold your breath? For even highly trained humans, it’s a few minutes, tops. Compare that with the killifish, which can survive without oxygen for more than 60 days, by far the longest ...

A species of fish has evolved remarkably quickly so it can live in rivers and seas contaminated with highly toxic pollutants that would normally kill them, scientists have discovered. Atlantic ...

This Research in Action article was provided to LiveScience in partnership with the National Science Foundation. New research shows that a signal species of fish in the Gulf Coast was harmed by ...
