Researchers in Denmark have discovered a way to detect early signs of testicular cancer before it has started to spread. Their findings are the first step towards developing a simple screening test for men at risk of the disease.
Writing in Europe’s leading reproductive medical journal Human Reproduction today (Thursday 3 March), doctors from the Rigshospitalet in Copenhagen report the first diagnosis of pre-invasive testicular carcinoma in situ (CIS) in a semen sample from a 23-year-old man. The man had been included in the researchers’ study as a supposedly healthy control, with suspected infertility problems but no suspicion of cancer.
There are about 13,200 new cases of testicular cancer each year in Europe and it is the commonest cancer in men between the ages of 20 and 39. Nowadays more than 90% of cases can be cured, especially if caught early. However, it is often difficult to detect the cancer before it has started to spread. This means that surgery is usually accompanied by chemotherapy or radiotherapy, both of which may cause infertility.

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,...
