At the nanometer scale, matter exhibits strange, new behaviors. Nanotechnology
researchers harness those behaviors to create new devices and materials, and use
the nanoHUB to access simulation tools, educational materials and computing resources
necessary to study matter at the nanometer scale. New middleware allows the nanoHUB to
act as a conduit to grid computing resources from several infrastructures.

The Global Grid Forum
The Global Grid Forum is the community of users, developers, and vendors
leading the global standardization effort for grid computing. The GGF community, which
consists of thousands of individuals in industry and research, representing over
400 organizations in more than 50 countries, works for the pervasive
adoption of grid computing worldwide.

e-VLBI Measures Earth and Sky

The technique of Very Long Baseline Interferometry has been used since the late 1960s by astronomers to make detailed images of distant radio-emitting objects in the universe, and by geoscientists to precisely measure the dynamics of the Earth. This well-established technique uses an array of independent antennas, scattered over the surface of the earth and synchronized with atomic clocks, to make simultaneous observations. With the use of global multi-gigabit optical networks, VLBI may be poised for a major upgrade.
"VLBI was originally developed by radio astronomers to make high-resolution measurements of quasars," said Alan Whitney from the Massachusetts Institute of Technology's Haystack Observatory. "In some VLBI observations, scientists can make high-resolution images of a distant radio source equivalent to discerning the dimples on a golf ball 3,000 miles away. The distances between the antennas can also be measured to an accuracy of a few millimeters anywhere on the surface of the Earth. This allows geophysicists and geologists to make direct measurements of the motion of the tectonic plates, as well as extremely accurate measurements of the motion of the Earth in space."
Traditionally, VLBI data from up to 20 antennas are simultaneously recorded to magnetic tapes or disks and physically shipped to a central location, where a specialized processor called a correlator searches for common signals in the data. High-speed networks directly linking the antennas with the correlator would allow scientists to view the correlated signals very soon after they are recorded and adjust their observations accordingly. A networked e-VLBI system would also have the potential to move data at much higher rates, dramatically increasing the technique's sensitivity.

Call for Topics for the e-Science Institute Thematic Program
The e-Science Institute, situated in Edinburgh, Scotland, is the United Kingdom's Centre
for e-Research Meetings. The Institute has recently introduced a
thematic mode,
which concentrates on in-depth and sustained investigation of a topic by a series of linked
talks, workshops and conferences over a period of six months to a year.
Proposals are due by November 14, 2005 for topics for the next two themes, which
will run throughout 2006. The proposals, which will be reviewed by the eSI Science
Advisory Board in early December, can be made either by the research community,
in which case eSI will try to find an appropriate leader, or by
potential theme leaders.
The e-Science Institute, funded by the e-Science Core Programme, has run over
350 meetings attended by 10,500 delegates, and hosted 46 visitors who have stayed
for varying periods from one day to a year, since August 2001. The Institute runs
a responsive mode program as well as a thematic mode. Theme leaders are long-term
funded visitors to the Institute. Currently, eSI has two active themes: Information
Services for Smart Decision Making, led by Jennifer Schopf from Argonne National
Laboratory; and Exploiting Diverse Sources of Scientific Data. The first events for
the latter theme will occur in November 2005 and are now open for registration.
To propose a theme or if you have any questions, please contact Anna Kenway
by email or phone (+44 (0)131 650 9818).

| LHC Physics, Networking Meet at Fermilab
Last Wednesday, October 12, over 70 physicists and network professionals met near Chicago to discuss data transfer requirements for U.S. participants in experiments at the Large Hadron Collider, the world's largest particle accelerator. The North American LHC Tier 2 Networking Meeting, sponsored by Internet2 and the Department of Energy's Energy Sciences Network, was held at Fermi National Accelerator Laboratory.
Over 400 physicists at U.S. universities and laboratories plan to study the fundamental properties of particles and forces using data from the CMS and ATLAS experiments at the LHC, currently being built at CERN in Geneva, Switzerland. When the LHC begins operating in 2007, data will be collected at the CMS and ATLAS detectors and sent over high-speed networks to large Tier 1 computer facilities worldwide, including Fermilab and Brookhaven National Laboratory in the United States and TRIUMF in Canada. The Tier 1 facilities will then send data to the Tier 2 computing facilities, located at universities across North America.
"The first goal of this meeting was to get the networking folks at the universities together with the physicists, and get communications going about the LHC project and Tier 2 centers," said Rick Summerhill from Internet2. "The second goal was to see where we were on supporting the connectivity down to the Tier 2 sites."
