Scientists coax mice with injured spinal cords to regrow nerve fibers, something deemed impossible not too long ago

With the help of a novel drug therapy, mice with spinal cord damage showed nerve cell regeneration at the injured site.

Gene key in neuron generation discovered

Scientists have discovered an atypical gene that is thought to be crucial for the generation of new neurons in the brain, a process called neurogenesis. The discovery and further study of the gene might help scientists better understand how neurodegenerative diseases such as Alzheimer’s affect the brain and, in term, how to address them. New neurons are born through a

Tadpoles can see through eyes implanted in their tails

Most animals have eyes in the vicinity of their brains, typically inside the head, since these are very sensible organs that require a very sophisticated neural link. Recently, biologists at Tufts University have shown that they could implant working eyes in other locations as well, after they granted blind tadpoles vision after they implanted eyes in their tails. The findings might

Crabs and other shellfish feel pain. Opens ethical discussion

A new study from researchers at Queen’s University Belfast, UK, found that indeed shellfish, like crabs or lobsters that are typically cooked alive in horrid conditions, feel pain as well. The findings raise significant ethical discussions, warning the food and fish industry of its ill ways of killing live seafood. “On a philosophical point, it is impossible to demonstrate absolutely
