Brazils Pantanal, a vast wetland situated in the center of South America, has become the next frontier for leading-edge eco-tourists in search of ever more exotic flora and fauna. "Its where people go after theyve been to Africa," says Shannon Bouton, a Ph.D. student in the School of Natural Resources and Environment (SNRE) at the University of Michigan.
This month, Bouton is publishing the results of her unique study of a wading bird colony in the Pantanal in the February issue of Conservation Biology, the journal of the Society for Conservation Biology. The article, co-authored with Peter C. Frederick (University of Florida), is titled "Stakeholders Perceptions of a Wading Bird Colony as a Community Resource in the Brazilian Pantanal." Unlike other research projects that consider only the biological effects of tourism, Bouton has combined her biological research with a study of how the colony serves as a resource for the local community. Her practical suggestions for meeting the twin goals of managing and developing tourism and conserving the colony have attracted the attention of top government officials and diplomats in Brazil and have made her study site at Porto da Fazenda a model for similar efforts in the region.
Today, as a result of those suggestions, local forestry police have posted a guard in front of the colony to control the behavior of tourists and fishermen. A local conservation group, Associação Ecológica Melgassense (AMEC) has established a staffed observation post that is occupied year-round to protect the birds and the forest. AMEC trains young people from the community as guides to take tourists along newly constructed trails at a safe distance from the colony and runs workshops for local children and adults so that everyone is aware of the biology of the birds, their importance to the community and how to behave so as not to disturb them.

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.

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...
