The number of elderly is rising worldwide, and it is estimated that average life expectancy in Europe will reach 100 by the end of the century.
At the same time, old age and what we expect from it are changing. An extensive research project at the University of Gothenburg’s Sahlgrenska Academy has spent a number of years comparing the elderly of the 1970s with those of today. The project, known as the H70 study, reveals that old age has changed drastically in a number of ways.
For example, the proportion of elderly with schooling beyond secondary level has risen from 14% to almost 40% for both genders. This is reflected in a better performance in intelligence tests by today's 70-year-olds than their counterparts back in the 1970s.
The proportion of married people has increased, as has the proportion of divorcees. The elderly are also now more sexually active, and the number with sexual problems such as impotence has fallen.
The results of the long-term study can also be contradictory, not least when it comes to social networking:
“The H70 study shows that the elderly are more outgoing today than they were in the 1970s – they talk more to their neighbours, for example – yet the percentage of elderly who feel lonely has increased significantly,” says professor Ingmar Skoog from the University of Gothenburg’s Sahlgrenska Academy, who leads the study.
Old people’s mental health does not seem to have changed, however. Dementia disorders are no more prevalent today than they were 30 years ago, and while more old people consider themselves to be mildly depressed, more severe forms of depression have not become more common. Meanwhile the elderly are coping better with everyday life: the number needing help with cleaning has fallen from 25% to 12%, and only 4% need help taking a bath, down from 14% in the 1970s.
“Our conclusion is that pensioners are generally healthier and perkier today than they were 30 years ago,” says Skoog. “This may be of interest both in the debate about where to set the retirement age and in terms of the baby boomers now hitting retirement age.”THE H70 STUDY

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

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...
