A new, undescribed species of marine worm.
Coral reefs, coastal rainforest, land-grab, industrial bananas and organic cacao, mangroves, tourist boom, eclectic cultural mix: A Caribbean Journal of Science special issue presents the first scientific overview of the marine environment in Bocas del Toro Province near Panama’s border with Costa Rica. With color photographic guide to marine invertebrates--the volume, edited by Dr. Rachel Collin, director STRI’s research station in Bocas--debuts new species and new records for Panama and provides an essential reference for researchers, tourists and conservationists throughout the region.
"The known diversity in Bocas looks very good in comparison with other places in the Caribbean" explains Collin. "Sponges and some brittlestars are much more abundant on reefs here, and after only ten days of snorkel sampling, Bocas has already become the most diverse site for Nemerteans (unsegmented marine worms) and the second most diverse site for tunicates. Diversity is expected to increase with more intensive sampling." Collin found funds from the Smithsonian Marine Science Network and the Smithsonian Women’s Committee to invite a host of experts on different taxonomic groups to conduct marine surveys in 2003 and 2004, and to set up a baseline species inventory for the station.
Collin encourages interested researchers to contact STRI: "I hope that scientists and students will find the organisms they work with in our online database and decide to visit the station. We already have documented more than 3000 species." (see links)

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...

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...
