Genetic rescue of endangered species may risk bad mutations slipping through

Ohio State University
Peer-Reviewed Publication

The established conservation practice of relocating animals from large, genetically diverse populations to small communities of inbred endangered species may risk introducing more damaging than beneficial gene variants into the threatened group, a new study suggests.

New research compares effectiveness of common Atlantic sea scallop farming methods

University of Maine
Peer-Reviewed Publication

Researchers from the University of Maine are working to test and adapt scallop farming techniques to help grow the industry in the Gulf of Maine. This study analyzes the economic advantages and disadvantages of two common methods of scallop aquaculture: ear-hanging and lantern net techniques. Researchers used their results to develop a user-friendly application that compares the different costs and possibilities associated with starting scallop farms.

This snail’s eyes grow back: Could they help humans do the same?

University of California - Davis
Peer-Reviewed Publication

Human eyes are complex and irreparable, yet they are structurally like those of the freshwater apple snail, which can completely regenerate its eyes. A new study shows that apple snail and human eyes share many anatomical and genetic features.

Seeing with fresh eyes: Snails as a system for studying sight restoration

Stowers Institute for Medical Research
Peer-Reviewed Publication

The eye of the apple snail is unusually similar to a human eye—but, unlike human eyes, it can regrow itself if injured or even amputated. New research from the Stowers Institute for Medical Research has established the apple snail as a novel research organism to study eye regeneration, with the potential to better understand and find treatments for eye conditions in humans like macular degeneration.
