Children whose mothers are depressed after childbirth are at elevated risk for violence by age 11, especially if the mothers suffered repeated depression, according to new research involving British families. The study also finds that in contrast to their peers, children whose mothers had been depressed at three months postpartum showed more diverse and severe aggressive behaviors than other children. The findings appear in the November issue of Developmental Psychology, a journal published by the American Psychological Association (APA).
As part of an ongoing, longitudinal study of child development, researcher Dale F. Hay, Ph.D., of Cardiff University and colleagues studied 122 families living in two communities in South London to see what affect the mother’s postnatal depression has on the development of children’s violent behavior. The participants were representative of urban populations in contemporary Britain. Mothers were interviewed during pregnancy, at three months postpartum and when the child was one, four and 11 years old. Mothers, teachers and children were questioned about violent symptoms when the child was 11.
As expected, the researchers found that most children in the study were not violent. However, those children who had mothers that had been depressed in the months after childbirth were more violent than other children, especially if the depression occurred at three months postpartum and at least once thereafter. The violence was more common in boys at age 11 than girls and mostly involved fighting with peers. The fighting often led to injury and suspension from school.

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...
