Stress can lead to chronic fatigue later in life

Stress can have repercussions later in life in the form of chronic fatigue, according to a new study from Karolinska Institutet.

People who considered their lives to be stressful at the start of the 1970s today suffer more often from chronic fatigue than others. The study was carried out with data from the Swedish Twin registry.

Chronic fatigue is a condition characterised by long-lasting and abnormal exhaustion, often accompanied by concentration impairment, mood swings, insomnia and pain in the muscles and joints. Despite extensive research, no root causes have been identified; all that scientists know so far is that it seems to appear across all ages and social classes in many different countries.

A research group from Karolinska Institutet has now been able to show that one of the direct causes of chronic fatigue is stress. Using the results from a health survey conducted amongst almost 20,000 twins from the Swedish Twin registry in 1973 and of a repeat survey of the same population in 1998 (which contained questions about chronic fatigue), the researchers found that the group who claimed to have stressful lives 25 years previously ran a 65 per cent greater chance of developing chronic fatigue than those who did not.

The scientists also noted a correlation between emotional instability and chronic fatigue. By limiting the analysis to identical twins, the researchers were able to dismiss any causal relationship. Instead, the correlation should be interpreted as there being genetic factors that are important for both emotional instability and chronic fatigue. Using the same method, the team has been able to show that stress does actually have a direct impact on the risk of developing chronic fatigue.

“This is a very important step towards understanding a disease that we know very little about,” says Professor Nancy Pedersen, who has led the study. “Before we can develop effective treatments, we have to understand the underlying mechanisms.”

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
