On September 24th, 2008, the International Polar Year 2007-8 (IPY) will launch its sixth ‘International Polar Day' focusing on People in Polar Regions, especially on community and cultural well-being, health issues, and the role of the Arctic in the global economy.
This Polar Day occurs at the time when combined effects of modern climatic, environmental, economic, and social change challenge the resilience of many Arctic communities and when polar residents, IPY researchers, and public at large address the future of the polar regions from new societal, humanistic, and environmental perspectives.
During the week of September 24th, radio events streamed from the Arctic will connect researchers, communities, and classrooms from Canada and Greenland to Zambia, Brazil and Australia. The week’s events will also include global on-line discussions about communities, local classroom discussions and activities, and a global Polar Day virtual balloon launch.
More Information: A special webpage www.ipy.org/index.php?/ipy/detail/people has been prepared with information for Press and Educators, details of current projects, radio events, profiles and contacts for researchers around the world, images, background information and useful links and resources.
Background: People have lived in the Earth polar regions—in the Arctic, but also across the sub-polar fringes of the Southern Ocean—for many millennia, developing skills, strategies, and community knowledge to survive polar conditions. They succeeded by learning to use local foods from land and sea, by learning to move safely across land, ice, and ocean, by circum-Arctic trade, and by passing their knowledge to the next generations through language, culture, arts, and worldviews. In recent centuries resource exploitation and political activities imposed from outside the polar regions have changed the livelihoods and well-being of polar residents in many ways. Today, rapid environmental change and renewed resource exploitation present urgent challenges to polar people. IPY researchers, many of them from Arctic communities, address these and other social/human issues through their IPY science projects, education and outreach activities.
Radio: The Native Communications Society of the Northwest Territories is a non-profit Society operating CKLB Radio - an independent aboriginal community radio station based in Yellowknife, NWT, Arctic Canada. For 24 hours CKLB Radio will be connecting people around the world through an Internet radio stream that can be found at www.ncsnwt.com.
There will be three opportunities for the public to speak, live, with the radio show announcers and IPY experts. These occur at accessible times in Europe, the Americas, and Australasia. Classes in Zambia, Brazil, Australia, and Arctic Canada have already confirmed phone-in participation in these events. There will also be an opportunity to ask questions via the internet. An additional special programme scheduled on Canberra Community Radio’s weekly science program, Fuzzy Logic, will be broadcast on Sunday September 28th.For more information, visit
To enable a global discussion, Taking IT Global have developed a special webpage, http://polarday.tiged.org/, where classes internationally can share ideas, discussions, images, videos, and artwork around this theme. IPY Experts will also be on-line to answer questions from students.For more information, visit

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
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.
A warming planet
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...
