A giant among minnows: Giant danio can keep growing

...cells to grow and join to adjacent muscle fiber to repair the injury. There is also an application to fish farming. “If we understood how fish grow, we could figure out strategies for enhancing the growth of farmed fish such as Atlantic salmon and decrease the time to get to market size. “The more we unde...

St. Jude finds clues to hearing loss from chemotherapy

...tation disrupts that cascade might lead to ways to repair the damage, Zuo said. For example, one type of damage that occurs in children whose hearing is damaged by chemotherapy is loss of hair cells in the inner part of the ear. These cells sprout extremely fine hairs that move in response to sound waves a...

The lipids are probably used to repair the cell membrane, stopping the potassium leak, which itself can kill the cell, and also protecting the cell from additional toxic substances lurking outside. "This result is important, because it also explains so much in terms of basic cell physio...
