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.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
