A newly discovered mechanism by which an infectious fungus perceives light also plays an important role in its virulence, according to Howard Hughes Medical Institute investigators at Duke University Medical Center. The findings suggest that changes in light following fungal invasion of the human body may be an important and previously overlooked cue that sparks infection, the researchers said.
The discovery in the human pathogen Cryptococcus neoformans further suggests that light therapy, in combination with anti-fungal drug treatments, might offer an effective method to combat a variety of fungal infections, particularly those of the skin or nails, said HHMI investigator Joseph Heitman, M.D., James B. Duke professor of molecular genetics and microbiology and medicine at Duke.
Light therapy is now used for medical conditions, such as seasonal affective disorder. The most common method, called bright-light therapy, requires that patients sit near a special light box fitted with high-intensity, full-spectrum or white light bulbs. UV irradiation is also used to repigment skin affected by the autoimmune disorder vitiligo.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
