It is natural to suppose that conducting the same tests, with the same strain of mice and the same protocols on identical equipment but in different labs will ensure similar results. A University of Alberta researcher and his team have found that assumption not to be true--fuelling the nature vs. nurture debate and shedding some light on the importance of environmental factors in experiments.
Dr. Douglas Wahlsten, from the Department of Psychology, is part of a research team that use mice who share the same genetic make-up to study the relationship among an animals genetics, environment, and behaviour.
In a recent study to determine which kinds of tests done in different laboratories--in Alberta and Oregon--give the same results--Wahlsten and the research team first taught the mice how to use a particular apparatus and then tested motor co-ordination under the influence of alcohol.

Drone vs. truck deliveries: Which create less carbon pollution?

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
