In Europe, 8.5 million tons of tomatoes are cultivated annually. 1.5 million tons are sold directly to the consumer and 7 million are processed for products such as ketchup, sauces, etc. During this processing, some 40% of the tomato raw material ends up as residue mainly skin and seeds. The seeds, considered by the processing industry simply as waste or used as animal feed, is still an excellent source of nutrients such as carotenoids, proteins, sugars, fibre, wax and oils, these oils being nutritionally very valuable for their high unsaturated fats content.
Continuing with its line of research for evaluating food subproducts, the Basque research center AZTI is participating in the European project TOM (2003-2004), together with a consortium of European R&D companies and technological centres, to obtain natural food additives.
The fundamental aim of the European TOM project is the evaluation of this residue for obtaining and purification of these high-value nutritional compounds and their use as ingredients in the formulation and manufacture of functional foods or of foodstuffs the consumption of which provides additional health benefits, i.e. other than those nutrients provided by their intrinsic composition. The extraction of these substances will provide additional benefits and a significant reduction in the tomato residue generated in the tomato processing industry, up to 30%.

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...
