Professor Pierre Delaere (Otorhinolaryngology section, K.U.Leuven) has in the past decade developed a new surgical technique for larynx reconstruction. In an increasing number of cases, this innovative technique can save the larynx in patients suffering from vocal cord cancer. Patients are able to breathe, swallow and speak normally following the operation, something that was previously impossible since the entire larynx frequently needed to be removed, even if only one vocal cord was affected.
The larynx separates the digestive system and the respiratory system. If the larynx is removed then the separation must be effected in some other way. Persons without a larynx can still eat if the oesophagus is connected directly to the oral cavity. However, this means that breathing through the mouth and nose becomes impossible and a permanent opening (stoma) for the trachea has to be made in the patient’s neck. This is a very conspicuous intervention and results in many problems of adaptation. Speech is still possible using an apparatus placed in the stoma, but the patient must cover the opening with his finger.
Prof. Delaere investigated why the larynx was completely removed in almost every case. In part, this is a result of the complex structure of the larynx itself. If part of the larynx is removed, two main problems arise: new tissue must be found to replace what has been removed, and the supply of blood must be optimal to ensure that the new tissue does not die.

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:...

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,...
