Although it seems obvious that when overweight people lose weight their health should improve, the relationship between weight loss and health may not be as simple as that, suggests previous studies from Finland and Denmark. For example, it is difficult to control for all other possible things that might cause weight loss, such as other medical conditions that could then increase mortality.
The researchers at the University of Helsinki, Helsinki and Copenhagen University Hospitals, Danish Epidemiology Science Center and National Public Health Institute in Finland started with a population of 19 993 Finnish twins who were asked in 1975 about their weight and whether they were attempting to lose weight. In 1981, they were asked again about their weight, and then followed for up to 18 years to see who died. The researchers looked at the 2 957 who were overweight or obese (BMI at least 25) and took out of the analyses all the people who had illnesses, or those who had data missing, and analysed mortality against intention to lose weight in 1975 and actual change in weight.
They found that those people who intended to lose weight and who actually did so had a somewhat higher mortality than those who gained weight or whose weight remained the same. In people who did not intend to lose weight, gaining weight was associated with a somewhat higher mortality.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
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,...
