In airports on both sides of the Atlantic, BioWise is taking off as a leader in the provision of multi-biometric and multi-modal identification and authentication middleware for safer air travel.
Working with SITA and UNISYS, the BioWise system is in use in the US’ large-scale registered traveller’s pilot programme for internal flights. “In return for registering,” explains André Oeyen, Managing Director of BioWise, “they will be considered as trusted travellers and will be granted some privileges, allowing them to pass faster through the airport gate.” This is only once they are accepted into the programme, and have their smartcard with their biometric details authenticated at the BioWise kiosk. During registration travellers have both their index fingers and irises scanned and stored according to International Civil Aviation Organisation recommendations for biometric information storage, and have valid forms of identification checked by the police authorities.
Initially deployed in airports in Minneapolis, Los Angeles, Houston for a trial period of 90 days, after well over 120 days it is still in use by thousands of registered travellers instead of the planned hundreds. Its reported popularity among travellers make it likely that more kiosks will be rolled out next year across the 500 US airports that qualify for this kind of infrastructure, believes Oeyen.

Researchers 'count cars' -- literally -- to find a better way to control heavy traffic

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...
