Office 365 Goes to the Movies

Think of how movies would be different if they'd only had Office 365. How can mobsters keep tabs on enemy families? Presence in Lync. How can the beleaguered sheriff keep law and order in the Old West? Shared Outlook calendars. See how in The Office Show Classic Film Festival! They don't make movies like these anymore.

7.341 Brightening up Life: Harnessing the Power of Fluorescence Imaging to Observe Biology in Action
One summer in the 1960s a young Japanese researcher, with the help of a few high school students, chopped up ten thousand jellyfish. As a by-product of this harvest, they isolated a green fluorescent protein (GFP). Since then, GFP has triggered a revolution in our understanding of gene expression and signaling in live cells. In this seminar, we will examine how this small protein generates fluorescence, i.e. absorbs light of one wavelength and emits light of a longer wavelength. We will discuss

Conclusion

  1. Eutrophication is a process in which an ecosystem accumulates mineral nutrients. It can occur naturally, but is usually associated with human activity that releases nutrients into the environment.

  2. Anthropogenic eutrophication has caused a widespread loss of biodiversity in many systems. Recent attempts to reverse the process are proving difficult and expensive.

  3. Symptoms of eutrophication are most readily seen in aquatic sys

5.2 Energy sources in torpor and hibernation

For animals that show daily torpor, such as Siberian hamsters (Phodopus sungorus) and Djungarian hamsters (Phodopus campbelli) (Figure 28), blood glucose remains the respiratory fuel for several hours following its onset. Thereafter there is a gradual reduction in respiratory quotient (RQ) indicating a change to lipid metabolism as the metabolic rate is reduced.
