... dinosaur fossils with missing pieces -- sets of teeth without a jaw bone, bones that are pitted and grooved, even bones that are half gone. Now a Brigham Young University study identifies a culprit: ...
... have discovered that cellular distress signals cause one segment of Bak to flip out and insert neatly into a groove on another Bak molecule. The Bak doublet then forms the larger complexes that can ...
... the Arch domain forms a curious archway over a tunnel-like opening at the end of a long groove. Given the electric charge of the amino acids lining the groove, the topograpy suggests a passageway for ...
... around Saturn gives an insight into the processes that drive planetary formation, where the proto-planet collects material in its orbit through a dust plane and carves out similar grooves and tracks."
... score the bone that holds the teeth in place and then applies bone graft material over the grooves. The procedure is done under local anesthetic in the dental office operatory.
As the bone begins ...
... , some pastes polish the surface but also unnecessarily ablate the tooth material, producing slight grooves on the tooth surface. The ideal paste, on the other hand, polishes so lightly that only the ...

Burns' system offers six-by-six millimeter blocks etched with different arrangements of grooves researchers can use to make a custom device by sticking them to a piece of glass. Block ...

In this image, at least two families of grooves with distinct orientations can be seen along with an elongated crater.
The stereo observations (resolution ...
