With exposed sensors, measurement taken in daylight read too warm, and while solar heating had a measurable impact on the earlier designs, the effect became negligible in more recent designs.

...t developed at RML a decade ago, the research team exposed two groups of 6-week-old mice to different strains of the agent that causes scrapie, a brain-wasting disease of sheep. Within 150 days of being inoculated with the natural form of scrapie prion protein, all 70 mice in the control group showed visible...How HIV disables the cells' call for help
.... The researchers suspected that FP, which is only exposed for a short period during this process, may have enough time to affect the immune response as well. Indeed, they found that FP locks on to several proteins on the cell walls that are involved in invoking a large-scale immune response, effectively shu...Molecular mechanism of feather formation found
.... In the first steps of feather development, cells exposed to essentially the same levels of Bmp2 and Shh grow from a small bud to form a uniform ring. Shh then is expressed in specific spots along the ring, giving rise to bumps, seen microscopically as longitudinal stripes demarcating the edges of ridges in...Hurricane aftermath: Infectious disease threats from common, not exotic, diseases
