“Ghost Forests” Expanding Along Northeast U.S. Coast

Why are “ghost forests” filled with dead trees expanding along the mid-Atlantic and southern New England coast? Higher groundwater levels linked to sea-level rise and increased flooding from storm surges and very high tides are likely the most important factors, according to a Rutgers study on the impacts of climate change that suggests how to enhance land-use planning.

Johns Hopkins Scientists Find Mammals Share Gene Pathways That Allow Zebrafish To Grow New Eyes

Working with fish, birds and mice, Johns Hopkins Medicine researchers report new evidence that some animals’ natural capacity to regrow neurons is not missing, but is instead inactivated in mammals. Specifically, the researchers found that some genetic pathways that allow many fish and other cold-blooded animals to repair specialized eye neurons after injury remain present in mammals as well, but are turned off, blocking regeneration and healing.

Tail regeneration in lungfish provides insight into evolution of limb regrowth

A new study published in the Proceedings of the Royal Society B from researchers at the University of Chicago and Universidade Federal do Pará explores regenerative ability in the tails of West African lungfish for the first time, and finds that the process shares many of the same traits as tail regeneration in salamanders. Their results indicate that this trait was likely found in a common ancestor – and provide a new opportunity for better understanding and harnessing the mechanisms of limb regrowth.
