Cell signalling

...technology, the DNA encoding the domain of interest is inserted into a plasmid vector just downstream of, and in the same translation reading frame (ORF) as the gene for GST. Under optimized conditions, certain strains of bacteria are induced to take up the plasmid and grown in selection media. Expression of the fusion protein is then chemically induced in transformed...

Artists and authorship: the case of Raphael

...technologies of power. Greenblatt focuses not only on the ideological construction of the human will. He also underscores the notion that the Renaissance offered new opportunities for the individual, such as the ability to change one’s religious beliefs or one’s social standing. Art (especially, one would imagine, portraiture) gives us insight into the continual...

A tour of the cell

...technology of centrifugation allowed samples to be spun at very high speeds indeed, a refinement known as ultracentrifugation. For example, a centrifugation speed of 30 000 revolutions per minute (rpm) can produce a centrifugal force of 100 000 times Earth's gravitational force (100 000 × g). Ultracentrifugation using the appropriate types of sample preparation and...

Astronomy: images of the Universe

...technology over hundreds of years has been the desire to make sharper, more detailed images. In other words, to improve the spatial resolution with which we can measure the sky, allowing us to obtain these detailed views of individual objects. But in parallel with these precision views, astronomers have developed the ability to map structure in the sky on scales much...

...technological development in the late 20th century has enabled scientists to derive bathymetry using data from satellites orbiting the Earth at unprecedented resolution. But because of the way the satellites orbit the Earth the resolution of the data decreases towards the North and South Poles. What will happen to the amount of detail that can be seen if the resolution of...

...educated delinquents) and council estates (Fergusson and Muncie, 2008). Council estates have also featured as convenient backdrops of social disorganisation in popular fiction and journalism, in travelogues, and as a source of political commentary and policy debate. In the late 1990s and early 2000s, for instance, it was the council estate which was marked out by the New...
