Space Station Live: Measuring Fluid Shifts on Orbit
NASA Commentator Pat Ryan talks with Dr. Michael Stenger, one of the co-principal investigators of the Fluid Shifts experiment now underway on the International Space Station. Researchers are trying to quantify the amount of fluids that shift to an astronaut’s head and upper body and into and out of cells and blood vessels during an extended period in weightlessness, determine if that increased fluid pressure inside the head and on the back of the eye are responsible for the diminished vision

7.3.2 Identify the outcomes you hope to achieve

An outcome is the result or consequence of a process. For example, you may want to produce an accurate analysis of some survey data, and to do this you may need to improve and apply your statistical skills. In this case the result of your analysis is an outcome, and using your number skills is part of the process by which you achieve that outcome.

Try to express the outcomes you hope to achieve as clearly and accurately as possible, asking others for help and comments if necessary. To h

2 A 4.6 billion-year history

Climate change is a natural process of warming and cooling that has occurred all through the Earth's history. Throughout geological time there have been ‘hot-house’ periods and ice ages. In order to understand the current situation, it is necessary to have some sense of context and perspective, from historical and geological time-scales. The document below shows a chart showing a generalised temperature history of the Earth.

1.5.3 Desktop search tools

Finding your paperwork or electronic files can be a problem. You may find that even if you do have some sort of filing system, your structure soon gets quite large with files in multiple locations, which can be hard to navigate. You may find yourself making arbitrary decisions about which folder to place a document in. It may make sense now but in the future, when you look where you think it should be, it’s not there.

At times like this you may resort to the search command from the Wi

7.6 Synaptogenesis

The formation of synaptic connections is an essential property of nervous system development. Synapses are formed between neurons and also with targets that are not part of the nervous system, e.g. muscle. Axon terminals, under the direction of a variety of extracellular cues, grow towards particular targets. Once they arrive at the target, they stop growing and the growth cone changes to form a synapse. As with axon growth, the formation of the synapse is dependent on an interaction between

6.2 (a) 'Cleaning-up' fossil and nuclear technologies

This means mitigating some of the adverse 'environmental' consequences of fossil and nuclear fuel use through the introduction of new, 'clean' technologies that should substantially reduce pollution emissions and health hazards. These include 'supply-side' measures to improve the efficiency with which fossil fuels are converted into electricity in power stations; cleaner and more efficient combustion methods; the increasing use of 'waste' heat in combined heat-and-power schemes; and 'end of p

2.6 How can we find out more about Europa?

There are currently no scheduled missions to Jupiter's moons, since NASA's Jupiter Icy Moons Orbiter (JIMO) was cancelled in 2005, but Europa remains a high priority target for both NASA and ESA, so a mission with simlar objectives to JIMO seems likely by about 2020. On arrival at Jupiter, JIMO would have gone into orbit first round Callisto, then Ganymede and finally Europa.

The main objectives of JIMO at Europa would have been to:

3.2 The agreement to protect the ozone layer

After a decade of controversy about the possible effects of CFCs, in 1985 British scientists discovered over the Antarctic a quite unexpected 'hole' in the ozone layer which was the size of the USA. This helped to galvanise the international community into action (though some who took part in the negotiations claim it played little part). By 1987 the first international agreement to control substances damaging to the ozone layer, the Montreal Protocol, was established. Interestingly th

3 The Efficient Markets Hypothesis (EMH)

The classic statements of the Efficient Markets Hypothesis (or EMH for short) are to be found in Roberts (1967) and Fama (1970).

An ‘efficient’ market is defined as a market where there are large numbers of rational, profit ‘maximisers’ actively competing, with each trying to predict future market values of individual securities, and where important current information is almost freely available to all particip

Science Video for Kids: How Are Clouds Formed?
(NOTE: The cumulonimbus cloud should be shown larger.) Have you ever looked at clouds? Clouds are fun to watch and think about. But, what are they, really? Clouds are made of water drops. They can be white or gray. Clouds are named for how they look. We'll look at these types of clouds: cumulus, cirrus, stratus, nimbus, cumulonimbus, and nimbostratus. Clouds tell us about the weather.

4.3 Golden Rice in the public domain

In January 2000, the successful experiments were announced in a paper published in the American journal Science. This, in itself, is significant. Generally, work on genetic manipulation would be published in one of a number of more specialist journals. Publication in a journal like Science indicates that this was important work, likely to be of interest to a wider audience. In its 'Notes for Authors', the journal states that 'Priority is given to papers that reveal novel concept
