“Frankenstein Dinosaur” mystery solved

Scientists have solved the puzzle of the so-called “Frankenstein dinosaur”, which seems to consist of body parts from unrelated species. A new study suggests that it is in fact the missing link between plant-eating dinosaurs, such as Stegosaurus, and carnivorous dinosaurs, like T. rex. The finding provides fresh insight on the evolution of the group of dinos known as the ornithischians. The study is published in the Royal Society journal Biology Letters. Matthew Baron, a…

Goldfish turn to alcohol to get through winter in icy ponds

Scientists have figured out how goldfish produce alcohol to survive when trapped beneath the icy surfaces of frozen lakes and ponds. Unlike most vertebrates which die within a few minutes without oxygen, goldfish and their wild relatives crucian carp are able to survive for months in oxygen-free water. Biologically speaking, the fish convert their anaerobically produced lactic acid into ethanol which diffuses across their gills into the surrounding water. The researchers from the Universities of…
