"This new approach builds on research in the computer science community over the past 40 years. For much of that time, many claimed this line of work was of academic interest, but of no practical relevance. Daniel's paper has shown how it has real application in tackling some of the key challenges facing the world today, such as climate change," says Professor Paul Watson of Newcastle University who chaired the AHM programme committee.
The BBC Climate Change Experiment is working with climateprediction.net, a major UK e-Science project funded by the Natural Environment Research Council. More than 200,000 people worldwide are participating in the experiment by donating spare capacity on their computers to run models of the Earth's climate.
As the dataset containing all model runs is too big to return to one location for analysis, it is stored on a number of servers in different locations worldwide. The challenge arises because the number of pieces this dataset is split into varies for a range of reasons, including the addition or removal of servers from the experiment, and the sub-setting of runs required for a given query. Climateprediction.net needed a way of analysing the data in situ that could also cope automatically with changes to the location or sub-division of data.
"Existing workflow languages are not up to the task because they implement a style of programming where the number of data inputs and the paths of data flow through the workflow are set when the workflow is submitted. This makes them unable to cope with subsequent changes to the dataset," says Daniel. He turned to constructs inspired from functional programming to solve the problem. These allow the workflow to adjust to the requirements of the data at run time and mean that changes to the way in which a dataset is split can be accommodated dynamically, so removing the need for users to keep adjusting their workflows.
Martlet has potential for use in many e-Science applications which distribute data between servers in a similar way to climateprediction.net. Its development also suggests that there could be other powerful new algorithms awaiting discovery once people start to think in terms of this alternative programming model. "Daniel's work has shown how work on core computer science can be used to meet the exciting challenges generated by e-Science applications. He has demonstrated how taking a different approach to organising the way in which tasks are executed can produce scientific results much more quickly," says Paul Watson.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
