Numerous studies, employing a wide variety of methods, have been carried out to determine the typical caffeine content of commonly consumed beverages. This application note details how UV spectroscopy ...

Sunlight has ultraviolet (UV) rays that can change the DNA in skin cells in ways that lead to cancer. Sunlamps, tanning booths, and X-rays also make these UV rays that damage skin.

Caffeine could be a useful addition to sunscreens since it both absorbs ultraviolet light and protects against skin cancer, scientists have said. The Standard Sign in ...

Studies with mice found that moderate amounts of caffeine and exercise lowered the skin cancer risk from UV light exposure. Karen Hopkin reports. If you're enjoying this article, consider ...

Caffeine acts as a sort of "sun screen" when given to mice before their skin is exposed to and damaged by ultraviolet B (UVB) radiation, and this ultimately prevents the development of skin cancer ...

Scientists believe the chemical found in coffee absorbs ultraviolet radiation when applied to the skin and prevents tumours after exposure to sunlight. They found in experiments that mice were ...

In this laboratory, students will see how to isolate caffeine from a cup of coffee and use spectroscopy to measure the amount of caffeine present. Get the Lab Handout (teachers request answer key) Lab ...

A lens for viewing UV light A series of coated lenses can allow people to see ultraviolet light superimposed onto the visible spectrum, extending the range of our senses without the need of ...
