In a society increasingly fixated with body image, we are bombarded with so-called scientific evidence promoting the use of a myriad of diets. An article published today in the Open Access journal BMC Medical Research Methodology suggests that we shouldn’t take everything we read at face value, as most research articles reporting weight loss studies fail to indicate crucial patient characteristics that may bias the results.
Cheryl Gibson, from the University of Kansas School of Medicine, and colleagues found that over 90% of diet studies did not adequately and comprehensively describe their subjects, making them almost impossible to interpret accurately.
In the USA, 97 million adults are overweight or obese. Extensive studies on the role of diet, exercise and genes are being carried out in a general effort to better understand and prevent obesity.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...
