The practice of extracting baby canine teeth to make way for adult canines that are erupting in the wrong place has no evidential basis, according to a new study by Cochrane Researchers. In a systematic review, the researchers were unable to identify a single high quality study to support the practice.

In an unusual intersection of materials science and anthropology, researchers from the National Institute of Standards and Technology (NIST) and The George Washington University (GWU) have applied materials-science-based mathematical models to help shed light on the dietary habits of some of mankindâ€™s prehistoric relatives.
A paper in this week's PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me.
Pyrosoma atlanticum is a species of colonial tunicate found in temperate waters worldwide, usually between 50°N and 50°S. It is most plentiful at depths below 800 feet. It is found in colonies that are pelagic and move throughout the water column. In the evening the colony will move closer to the surface and descend back by dawn. Large colonies can rise and descend more than 2,500 feet in a single day. A colony of this species is cylindrical and can grow up to 2 feet long and 2.5 inches...
Heterodontosaurus, meaning "different toothed lizard", is a genus of dinosaur from the Early Jurassic Period of what is now South Africa. The type species, H. tucki, was found in the Upper Elliot Formation of the Hettangian age (199 to 196 million years ago). Two species are known. This herbivorous dinosaur ate mostly plants despite having canines. It was a small ornithischian reaching a total length of 3 feet. It had a long, narrow pelvic bone which was like more advanced ornithischians....
The Giant Pangolin (Manis gigantea), is a species of pangolin. The Giant Pangolin inhabits Africa with a range stretching along the Equator from West Africa to Uganda. It is found mainly in savanna, rainforest, and forest, where there is a large termite population and available water. It does not inhabit high altitude areas. The Giant Pangolin is the largest species of pangolin (scaly anteaters). It belongs to the Manidae family. It was first described by Johann Karl Wilhelm Illiger in 1815....
The Southern Alligator Lizard, Elgaria multicarinata, is a lizard native to the Pacific coast of North America. It is common throughout Southern California and can be found in both grasslands and urban areas. Several subspecies can be distinguished, including the San Diego alligator lizard. It has a prehensile tail up to twice the length of its body. Like many lizards, however, it can drop its tail if attacked, possibly giving it a chance to flee; the tail will regenerate, but will never...
The Triplewart seadevil, Cryptopsaras couesii, is a seadevil of the family Ceratiidae, found in all oceans, from the surface to 1.24 mi (2,000 m). Its length is approximately 11.81 in (30 cm). The Triplewart seadevil is one of the most abundant of the deepwater anglerfish. These fish have round flabby bodies with a soft fibrous skeleton and a scaleless prickly skin. Like most other deepwater anglerfishes this fish has small eyes, no pelvic fins and is colored black. It has a large...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
