Laughter increases altruism

A new study from psychologists at the universities of Kent and Liverpool has revealed that laughter increases altruism towards strangers, a finding which may have important implications for charities and other fundraising bodies.

The study, conducted by Professor Mark van Vugt, Charlie Hardy, Julie Stow and Professor Robin Dunbar (University of Liverpool), was designed to examine if laughter acts as a social lubricant by enhancing a sense of group identity among strangers.

For the study, participants watched a funny or serious video clip before playing an altruistic game with strangers. The study revealed that after watching the funny clip subjects who laughed a lot were more likely to give their money to strangers. Further research suggests that this may be due to the effects of laughter on endorphins (naturally produced neurotransmitters that improve people’s mood).

Professor van Vugt, a member of Kent’s Centre for the Study of Group Processes and an expert on human altruism and co-operation said: ‘This study may have important implications for the way charities or organisations could increase the level of received donations. For example, Comic Relief – which in itself is a worthy event supporting many great causes – demonstrates how laughter can have a tremendous effect on giving.’

Professor van Vugt also pointed out that humans may have evolved the capacity for laughter to quickly release positive emotions in order to facilitate group bonding – group living enabled our ancestors to cope better with a hostile environment.

‘From the perspective of increasing altruism in society,’ he said, ‘it is obvious that laughter deserves serious attention from both scientists and policy makers.’

The full results of the study – titled Laughter as Social Lubricant: A Biosocial Hypothesis about the Pro-social Functions of Laughter and Humour – are available at

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
