A child’s first word is always a time for celebration. Whether it’s "ma," "da," or "cookie," the fact that your child has begun to communicate verbally represents a significant step in his or her development – and your role as a parent. And while most infants understand a small repertoire of words by 12 months, there’s little knowledge of just how they build those vocabularies. In contrast, researchers know a fair amount about how toddlers’ language develops. While it might make sense to assume that younger babies learn language in much the same way as older babies, a new study published in the March/April issue of the journal Child Development finds that just isn’t so.
It turns out that younger babies learn words for new objects based on how interested they are in the object, whereas older babies attach more importance to whether the speaker is interested in the object. These findings suggest that parents might want to talk more about what their babies are interested in rather than what they, the parents, are interested in.
To explore this issue, researchers from Temple University in Philadelphia and the Universities of Delaware in Newark and Evansville in Indiana conducted two studies. In both, infants were taught new words for "interesting" or "boring" objects. The "interesting" objects were brightly colored and made noise or had moving parts. They immediately captured the babies’ attention. In contrast, the "boring" objects were dull in color and appearance.

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...
