This information could be used to conserve or rebuild reefs in areas affected by climate change, by changes in extreme weather patterns, increasing sedimentation or altered land use.
In reef-building corals variations within genes involved in immunity and response to stress correlate to water temperature and clarity, finds a study published in BioMed Central’s open access journal BMC Genetics.

A research team led by the Australian Institute of Marine Science, and in collaboration with Penn State University and the Aix-Marseille University, studied DNA variations (Single Nucleotide Polymorphisms, SNPs) across populations of reef corals found at a range of temperatures and water clarity along the Great Barrier Reef.
SNPs which correlated to water clarity and water temperature preferred by cauliflower coral were found in genes involved in providing immune response, and regulating stress-induced cell-death. This means that coral with a specific version of these genes tended to grow at higher temperatures (or water clarity) and another variant at lower. A similar story was found for staghorn coral - SNP in genes involved in detoxification, immune response, and defense against reactive oxygen damage, were found to be associated with temperature or to water clarity.
Dr Petra Lundgren, from The Australian Institute of Marine Science, explained, "Corals are particularly vulnerable to climate change. Not only is the temperature of the water they live in affected but extreme weather and higher rainfall leads to increased levels of sediment, agricultural runoff, and fresh water on the reef. This work opens up possibilities for us to enhance reef resilience and recovery from impacts of climate change and pollution. For example, if in the future we need to restore coral populations, we can make sure that we use the most robust strains of corals to do so."

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...
