Fish represent one of the most diverse groups of vertebrates, exhibiting a wide array of physiological adaptations that have enabled them to colonise nearly every aquatic habitat on Earth. Central to ...

Parents pass down their genes to their offspring, and it seems that epigenetic features, which can affect gene activity without making changes to the DNA sequence, can also be passed down. New ...

Zebrafish are a great research model. They develop quickly and in their early stages, they remain transparent. The little fish are easy and inexpensive to raise and can reproduce more frequently and ...

Researchers from the University of Hawaii, the Wildlife Conservation Society, Smithsonian Tropical Research Institute, National Marine Fisheries Service and Projecto Meros do Brazil discovered a new ...

The popular nursery rhyme This Little Piggy is an early childhood memory for many of us. It’s a poem that involves five little piggies, each corresponding to one of our fingers or toes. Kids love it, ...

A rare genetic defect that affects the so-called ALG2 gene can cause serious metabolic diseases in humans. Until now, its rareness and complexity made it difficult to study this congenital ...

Scientists use CRISPR to show how genes that control growth at the end of fish fins play the same role in fingers and toes. All vertebrates have the same basic body plan: head, spine, four appendages.

To survive in the frigid ocean waters around the Arctic and Antarctica, marine life evolved many defenses against the lethal cold. One common adaptation is the ability to make antifreezing proteins ...
