X-Rays and Imaging We commonly associate x-ray imaging with hospitals and broken bones, but why are x-rays the chosen source of radiation instead of visible light or electron beams? The high initial energy ...

Researchers from Tsinghua University in Beijing, China, recently published their findings on using the Monte Carlo method during the design of skin-like optical devices. The Monte Carlo method allows for ...

In 1963, Leon Goldman became the first person to report using lasers in dermatology. Goldman reported the effects of Ruby laser in the selective destruction of cutaneous pigmented structures, like black ...

Tissue welding is a relatively new procedure that aims to seal wounds and openings in a surgery using laser. The first tissue welding application using lasers was done in 1964 to join small blood vessels ...

A research team at Keio University in Japan devised a novel handheld viscosity sensor capable of quick, non-contact in situ measurements. Viscosity is a fundamental property for liquid analysis in a wide ...

Optical fibers show promise not just in long-range information transmission, but also in fully optical computers. Image courtesy of tOrange.biz What is optical computing? For many decades, the processing ...

Optogenetics is the emerging field of using light to control and study neuronal activity. In 2005, a Stanford University team was able to use a light-sensitive microbial protein to control the timing of ...

For women across all socioeconomic groups, breast cancer poses a large threat. Approximately 1 in every 8 women will be diagnosed with the cancer during her lifetime. Additionally, it is one of the leading ...

Compound eyes provide insects with the ability to quickly react to danger. These eyes posses a much wider field-of-view, higher light sensitivity, and superior sensitivity to motion when compared to the ...

Ever since graphene sheets were isolated from bulk graphite in 2004, two-dimensional materials have received an immense amount of interest for their unexpected and novel electronic and optical properties. ...
