How to keep photoreceptors alive.

O ver the last 40 years, there has been increasing success in the surgical treatment of retinal detachment in that the retinal reattachment could be achieved in a high proportion of cases but visual recovery was frequently poor. An explanation for this poor visual outcome was derived from work on experimental retinal detachment in which it was shown that photoreceptor cell death occurred becaus...

Why keep climate records - and how to keep them

For all our concern about the damage caused to art by the environment, there are no data which allow us to connect measured environmental variables with the rate of deterioration of the art in exhibition or storage. Recent proposals for rating the suitability of spaces and the vulnerability of individual objects require a durability of electronic data which is very unlikely to be achieved. This...

Video analysis is an effective tool in understanding physics and from the students’ point of view a popular activity. It sometimes occurs that movies recorded by students are not well fit for analysis: the motion may be too quick for recording with a normal camera or webcam, perspective distortion may cause problems, or manual collection of video data may be too timeconsuming. In the first case...
