A study of patients with kidney cancer has shown that radiofrequency ablation, a minimally invasive, kidney-sparing procedure, can be a successful treatment option for patients whose cancer has not spread beyond the kidney, report researchers at Wake Forest Baptist Medical Center.
Results from the three year study, which evaluated 22 patients who received the treatment, are published in the July issue of the American Journal of Roentgenology. The treatment uses computed tomography to guide the placement of a special needle-shaped electrode into the tumor. A radiofrequency current is then passed through the electrode to heat the tumor tissue and ablate – or eliminate – it.
Complete tumor ablation was achieved after a single treatment in 83 percent of the patients; an additional eight percent had complete tumor ablation after two or more treatments. None of the patients had long-term or serious complications. "These results are significant and encouraging because the incidence of kidney cancer in the United States has increased by 126 percent over the past 50 years," said Ronald J. Zagoria, professor of radiologic sciences at Wake Forest Baptist and principal investigator of the study.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
