The degree studied the relationship between the speed of growth of young dogs and the development of common skeletal diseases such as elbow dysplasia and hip dysplasia. A common conception is that rapidly-growing breeds have a greater risk of developing certain types of skeletal illness. However, no comprehensive research has been conducted in dogs in a domestic environment to establish this.
Normal growth curves have now been established for these breeds for the first time. It turns out that the four breeds have different patterns of growth and that bitches grow more slowly than dogs (males).
Surprisingly, the study showed that the Labrador retriever grows faster than the Newfoundland, Irish wolfhound and the Leonberger, indicating that the largest breeds do not necessarily grow the fastest. The predominating view of the correlation between rapid growth and high incidence of common skeletal diseases therefore has to be revised.
Through her doctoral work, Trangerud discovered a new condition in the skeleton of the Newfoundland, which she found in nearly half of the young dogs. The condition resembles human bone dysplasia, but it is presently unclear just what clinical consequences the condition has for affected dogs.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
