Breeding of strawberries variety "Old Black", which is of uncertain origin. This variety was created by pollination, not direct manipulation of the plant's genes. Molecular breeding is the application of molecular biology tools in a breeding program. Genetic engineering is typically defined as the introduction of non-native genes into an organism. An excellent example of transgenic modification is in the case of cold resistant strawberries. In one particular variety genes from the arctic flounder, a fish that lives in very cold water, were used to give plants resistance to cold. This modification works because of the genetics of the arctic flounder. It lives
Rearing Horse and Mounted Warrior 2009 investigation organised by the National Gallery of Art suggests that the statuette was cast near or after Leonardo's death in 1519 using the lost wax technique. The composition of the metal alloy is identical in all the parts of the statuette, apart from the modern pin used to attach the rider. Equestrian statuettes with only slight variations to the "Rearing Horse and Mounted Warrior" have been discovered over the years. They are often referred to by their location. Particularly the "Rearing Horse" at the Metropolitan Museum of Art in New York and in the Hunt Museum in Limerick, Ireland,
