Lein Applied Diagnostics Ltd, a Berkshire-based company that is developing a revolutionary new product to measure blood glucose levels in people with diabetes, has successfully completed clinical tests of its advanced prototypes and secured further investment from Seven Spires Investments, a member of Thames Valley Investment Network (TVIN). The funding will enable Lein to accelerate the development programme for its non-invasive optical instrument.
Diabetes is a major problem, with 1.8 million sufferers in the UK and over 170m worldwide. The numbers are predicted to rise dramatically due to an ageing population and the general increase in obesity rates. People with Type 1 diabetes must measure their glucose levels four or five times a day in order to control their condition; they currently take a blood sample from a finger prick test, which is painful, inconvenient and can be unhygienic. As a result, some people do not test themselves as often as they should, increasing the likelihood of complications such as heart disease and blindness.
Lein’s patented blood glucose meter could transform the way people with diabetes test their blood glucose levels. In recent clinical tests, an advanced prototype of the instrument, which uses an innovative optical measurement technique to track the amount of glucose in the eye, produced well correlated readings of blood glucose levels when tested on volunteers with widely varying ages. Successful tests have also been performed on volunteers with contact lenses.

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...
