For the past 50 years, researchers at Sahlgrenska Academy have followed the health of 855 Gothenburg men born in 1913. Now that the study is being wrapped up, it turns out that ten of the subjects lived to 100 and conclusions can be drawn about the secrets of their longevity.
Over the past half century, the University Gothenburg has hosted one of the world's first prospective studies of aging. The subjects are 855 Gothenburg men born in 1913.
The first surveys were conducted in 1963.Now that it has been determined that ten of the men lived to 100, the study is being wrapped up.
Various surveys at the age of 54, 60, 65, 75, 80 and 100 permitted the researchers to consider the factors that appear to promote longevity.
A total of 27% (232) of the original group lived to the age of 80 and 13% (111) to 90. All in all, 1.1% of the subjects made it to their 100th birthday.
According to the study, 42% of deaths after the age of 80 were due to cardiovascular disease, 20% to infectious diseases, 8% to stroke, 8% to cancer, 6% to pneumonia and 16% to other causes.
A total of 23% of the over-80 group were diagnosed with some type of dementia.
"The unique design has enabled us to identify the factors that influence survival after the age of 50," says Lars Wilhelmsen, who has been involved in the study for the past 50 years. "Our recommendation for people who aspire to centernarianism is to refrain from smoking, maintain healthy cholesterol levels and confine themselves to four cups of coffee a day.”
Correlation with the mother´s age
It also helps if you paid a high rent for a flat or owing a house at age 50 (indicating good socio-econmic standard), enjoy robust working capacity at a bicycle test when you are 54 and have a mother who lived for a long time.
"Our findings that there is a correlation with maternal but not paternal longevity are fully consistent with a previous studies,” Dr. Wilhelmsen says. “Given that the same associations have been demonstrated in Hawaii, the genetic factor appears to be a strong one." But still we found that this “genetic factor” was weaker than the other factors. So factors that can be influenced are important for a long life.
Two of the 100-year-olds dropped out of the study due to dementia and one for personal reasons. Facts about the other seven:
• Two lived at home and five in assisted living facilities
• None of them smoked
• All of them exhibited good temporal and spatial cognition
• All of them wore hearing aids
• Most of them wore glasses, were able to read and watch TV
• All of them were slim and had good postures
• All of them used walkers
"Normally we conducted the surveys at hospitals, but we visited the seven centenarians at home," Dr. Wilhelmsen says. all of them were clinically healthy, satisfied with their circumstances and pleased to be living where they were."

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
