We often think of sunlight as something that warms us, helps plants grow, or gives us a summer glow. But according to Dr.

Red light therapy (RLT) is a therapeutic technique that uses low-level wavelengths of red light to help treat skin conditions such as wrinkles and psoriasis. Though the treatment seems promising ...

Due to a large penetration depth in tissue, a high energy femtosecond (fs) laser in the wavelength window of 1600 nm – 1800 nm (NIR-IIb) is attractive in biomedical applications of multiphoton ...

Low-level clouds (LLCs), mainly composed of liquid water droplets, cool the climate system by strongly reflecting solar radiation back to space and thus play an important role in the Earth energy ...

When a photon of sunlight with the right wavelength strikes a chlorophyll molecule, that energy can be absorbed, exciting the molecule and leading to the production of sugars.

Blue light isn't just harmful—it can boost sleep and energy when used correctly Learn how proper exposure impacts aging bodies and daily function.

The human eye can perceive only a small range of wavelengths of radiation. Ali Damouh/Science Photo Library via Getty Images Color perception depends on the surrounding environment. Michael J. Murdoch ...

Each color in the visible light spectrum has a different wavelength and energy level. Blue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye ...

How to have more energy If you've ruled out contributing medical conditions, your sluggishness can usually be improved by both avoiding the things that deplete energy and doing more of the things ...

Carbon dioxide forces the Earth’s energy budget out of balance by absorbing thermal infrared energy (heat) radiated by the surface. It absorbs thermal infrared energy with wavelengths in a part of the ...
