The scientists examine several risk groups. One consists of 10-year-olds born at the University Hospital Jena whose mothers had treatment with glucocorticoids during pregnancy. Two other groups are being followed up by psychologists at the University of Leuven in Belgium and include two-year-olds and 25-year-olds whose mothers suffered from stress during pregnancy. „A unique group studied at the Academic Medical Centre, University of Amsterdam includes persons born in Holland during the Dutch „Hunger Winter“, of 1944/45,” reported Prof. Schwab.Scientists involved in the project use state-of-the art neuropsychological, neurophysiological, and MRI methods to analyse and compare biological and real age of the brain. The biotechnology companies Life Length in Madrid and Biocrates in Innsbruck measure biological age in chromosomes and screen blood samples to determine metabolic blood markers of age. “Environmental factors such as exposure to stress hormones or malnutrition during pregnancy change the readout of genetic information permanently,” reported Matthias Platzer, Head of Genome Analysis at the Leibniz Institute for Age Research in Jena. „These epigenetic processes significantly change stress sensitivity for the rest of life,“ explained Prof Schwab. „Increased stress sensitivity makes one vulnerable to age-related diseases such as stroke and depression,“ he added.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
