That picture in your wallet may relieve stress

06.09.2004


A research group at the Babraham Institute has found that the sight of a friendly face can reduce stress in sheep. This discovery, published in the journal Proceedings of the Royal Society: Biological Sciences, could point to the reason that many of us carry pictures of loved ones in our wallets or handbags.



The scientists, led by Professor Keith Kendrick, put sheep into a darkened barn on their own and showed them various faces, while recording their behaviour. Stress was measured by monitoring the number of times each sheep bleated, its movement within the barn and its heart-rate. Blood samples were taken to measure the levels of cortisol and adrenaline, which are both chemical indicators of stress.

When the sheep were shown faces of sheep familiar to them, they became less stressed, and showed fewer signs of agitation than when they were shown goat faces or triangles. The areas of the brain which control fear and the stress response also showed reduced activation.


All of the indicators of stress measured during the test showed significant reductions. These results provide evidence that face pictures may be useful for relieving stress caused by unavoidable social isolation in sheep, and possibly other animal species, including humans. Fear and emotion are controlled by the right-hand side of the brain of both sheep and humans.

Professor Kendrick comments “We are not aware of any studies investigating whether similar exposure to face pictures can decrease separation anxiety in humans although it is common practice to carry pictures of loved ones when separated from them. One method of relieving separation anxiety in young children may be to give them pictures of their parents to carry”.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
