Our immune system has the task of protecting us against bacteria and viruses. Our bodies are also equipped to handle everyday stress–that is, stress that lasts only briefly.
On the other hand, a difficult, stressful situation or long-term increase in stress can negatively affect the immune system. This kind of long-term stress can develop when a close family member dies or when adults are caught in tough, unmanageable situations.
The research study shows that children in highly-stressed families had a high level of cortisol, which is a biological marker of stress. This supports the idea that the children were stressed. The research study also points towards the fact that a high level of stress negatively affects the immune system–that is, it is not as resistant when the body is exposed to a high level of stress. Instead, the immune system reacts to substances in the body that should be left alone, which perhaps is linked to an autoimmune reaction.
The study included families with five-year-old children (derived from the ABIS [All Children in Southeast Sweden] study). The parents answered questions regarding stress and prospective difficulties that had impacted the family, such as divorce or unemployment.
The answers led the researchers to identify a group of children who probably experienced high levels of stress in their families, and a group of children who presumably had grown up with normal stress levels.
The research group at the School of Health Sciences in Jönköping will work further on the project to understand more about how a high level of stress can affect the body. This time, the researchers will turn to young people in the 18-22 age group.
“These young people can themselves report negative experiences in their daily lives and also negative experiences during their childhood” says Maria Faresjö, professor at the School of Health Sciences, which will also lead the continued research project.
The article, “Psychological stress in children may alter the immune response”, is being published in Journal of Immunology (2014, DOI: 10.4049/jimmunol.1301713).

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:...

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,...
