FISH-i-LOGY!

The ability to compensate for the sex bias caused by rising temperatures is an important trait that could help constrain the impacts of ocean warming on reef fish populations and other species. However the research also suggests that when developmental temperature is too hot there is a limit to this "transgenerational plasticity."

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) lack key features present in humans. Stanford University scientists have found a new middle ground with the development of a genome-editing toolkit to study aging in the naturally short-lived African turquoise killifish.

The greatest absence of evolution ever reported has been discovered by an international group of scientists: a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms' lack of evolution actually supports Charles Darwin's theory of evolution.

Amphiprion percula, AKA: clownfish, AKA: NEMO!

Adult sea turtles find their way back to the beaches where they hatched by seeking out unique magnetic signatures along the coast, according to new evidence.

A new study of dolphins and seals shows that despite their remarkable adaptations to aquatic life, exercising while holding their breath remains a physiological challenge for marine mammals. The study found a surprisingly high frequency of heart arrhythmias in bottlenose dolphins and Weddell seals during the deepest dives.
