Enabled by a project grant worth EUR 190,000 awarded by the Emil Aaltonen Foundation, researcher Kati Heinonen-Tuomaala will launch a new project entitled Aetiology of mental and behavioural disorders: Exposure to adverse prenatal and childhood environments. Heinonen-Tuomaala belongs to a research developmental psychology group at the Department of Psychology, University of Helsinki.
The project is part of a larger cohort study begun by Professor Johan Eriksson (Department of Public Health, University of Helsinki, and National Public Health Institute) that followed the growth and development of over 10,000 Finnish men and women from birth to late adulthood. Birth size and the gestation length have been considered indicators of environmental circumstances during the prenatal period, and the first aim of the project is to study whether these two have an impact on subsequent mental well-being. A second aim is to investigate the implications of a mother's stress during pregnancy for a person's mental well-being later in life; some of the subjects of the cohort study were exposed to maternal prenatal stress during the Second World War. The project will furthermore study whether childhood separation from parents affects mental well-being. The cohort study includes people who were sent to Sweden or Denmark as war children for a period of time.
The project will produce new knowledge about the significance of prenatal and childhood experiences for mental well-being. The material used in the project is unique both historically and globally.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
