Budding computer experts from around the world will this week begin their own tests of the latest software developed by the European DataGrid Project. Students attending the 2002 CERN School of Computing in Vico Equense, Italy, will be submitting jobs that can run anywhere on the Project’s current Grid, which is based at 10 computer centres throughout Europe. This is the first in a series of important tests using software from the DataGrid Project that will take place throughout the autumn, and which will include connections across the Atlantic.
"There has been a great deal of hype about the Grid over the past year, but precious few examples of people actually using a Grid. These computer science students - some of the brightest in Europe - are the perfect test drivers for our European computer Grid. They will push it to the limit - and beyond!" says Fabrizio Gagliardi, Director of the School and manager of the DataGrid Project.
The concept of Grids of geographically distributed computers is under development around the world as the biggest breakthrough in computer networking technology since the World Wide Web, which was developed at CERN. While the Web allows the rapid transfer of previously prepared information, the aim of the Grid will be to search out and use vast amounts of computing power across an interconnected worldwide network of tens of thousands of computers and storage devices. There is great potential for data analysis and problem solving in a range of scientific applications, from particle physics through earth observation to bio-medicine.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
