It is already acknowledged that, whether it is rescuing strangers from burning buildings, donating blood or returning a wallet found in the street, humans are among the few creatures that are generous and altruistic towards strangers.
However, Hardy and Van Vugt have discovered that within groups of strangers generous types are the most valued members of their group, with their findings showing that generous individuals receive more status, are more often picked as partners and mates, and more often appear as group leaders.
Hardy and Van Vugt examined altruism in laboratory groups in both a reputation (donations were made public) and no reputation (donations were anonymous) environment. They then looked at how fellow group members would rate each other. First they found that people donated more to the group when their donations were made public. Second, they found that altruists received greater status in their group and were more often chosen as group leaders. Finally, they found that altruists were more often chosen as partners in a follow-up task, whereas selfish individuals were being ostracized.
Hardy and Van Vugt concluded that niceness pays. ‘In a world where people can choose who they want to interact with, altruists create more opportunities for themselves than selfish people. One practical implication is that altruism in society can be fostered by encouraging people to publicly display their generosity.’
Hardy and Van Vugt are now extending their experiments to explore other aspects of what they refer to as ‘competitive altruism’, which will provide a new way of thinking about human sociality. (‘Competitive altruism’ explains why humans are unusually altruistic, especially in large groups. It explains many uniquely human qualities such as heroism, prestige, volunteering, and philanthropy).

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
