Eighty-three per cent of college girls surveyed diet to lose weight, regardless of their current body weight. A study published today in the open access journal Nutrition Journal (http://www.nutritionj.com/) also reveals that college girls practice unhealthy behaviours, such as smoking or skipping breakfast, to lose weight. By contrast, only 19% of them exercise enough to promote weight loss. The authors of the study conclude that all college girls, regardless of whether they are normal weight, overweight or obese, would benefit from counselling or open discussions about healthy dieting practices.
Brenda Malinauskas and colleagues from East Carolina University, Greenville, USA asked 185 college girls about their weight perception, dieting practices and physical activity.
Malinauskas et al. found that 83% of the girls reported trying to control their weight or having tried to control their weight, regardless of whether they were normal weight, overweight or obese. Of the 185 girls studied, 80% reported exercising to lose weight although 32% did not really take part in regular physical activity and only 19% of them actually exercised often and vigorously enough to lose weight. Eating low fat, low sugar foods, eating less than one wants and counting calories were other methods used to lose weight. The most maladaptive weight loss practice reported was smoking to lose weight – it was reported by 9% of the girls. The most unhealthy practice reported was skipping breakfast – reported by 32% of the girls.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
