Professor Mummery:There are multiple ways of interpreting this; one is the way it is widely used in the laboratory, the other is more formal. In the laboratory, we use it to mean that if the same researcher carries out an experiment (say) three times, or that another researcher in the ...
These are interactive so students can take part as they might in a real-world experiment. This works for as young as kindergarten and runs up to graduate level. STEM subjects covered are physics, chemistry, biology, earth science, and math. (Image credit: PhET) It's not necessary to ...
These clinical samples are difficult to collect and generally only contain a small amount of usable mRNA. In a singleplex relative quantification experiment, only one gene—either the gene of interest or the control—is amplified in each well. Assuming that each assay...
In biological experiments, independent variables are the aspects of the experiment that are changed to find an answer, while dependent variables are the features affected by those changes. Standardized variables must remain the same to avoid muddying the
As the first month of 2016 draws to a close, we decided to tap into our network and ask an esteemed group of architects, critics, theorists and educators to tell us what they are looking forward to this year in architecture. What are you looking forward to in architecture this year? Sa...
