The zebrafish, Danio rerio, is a tropical freshwater fish belonging to the minnow family (Cyprinidae) of order Cypriniformes. It is a popular aquarium fish, frequently sold under the trade name zebra danio, and is an important vertebrate model organism in scientific research. It is particularly notable for its regenerative abilities, and has been modified by researchers to produce several transgenic strains.
Any mammal, including humans, suffering from an injury to the central nervous system will lead to a life-long loss of the particular affected brain function. Some invertebrates, like the zebrafish, in contrast can regenerate parts of their organs, even the central nervous system. The zebrafish’s remarkable ability to regrew parts of its damaged brain has [...]
As any fourth grader will tell you, photosynthesis is (in layman terms), the process through which plants (and bacteria, algae, etc) get the sugars and other organic compounds they need using energy from sunlight. However, during last week’s synthetic biology conference in Boston, a biologist from Harvard took things to a whole new level, presenting [...]
