[43] [failed verification] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [ 44 ] Despite the importance of the sun to vitamin D synthesis, it is prudent to limit the exposure of skin to UV radiation from sunlight [ 45 ] and from tanning beds ...
Similarly, carnivorous plants reflect and absorb UV to attract prey to it. [10] They mimic the strategy used by traditional flowers for pollination to exploit pollinators to land in the trap so the carnivorous flower head can digest them as a source of key nutrients to grow and survive.
UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [ 65 ] In the past, UVA was considered not harmful or less harmful than UVB, but today it is known to contribute to skin cancer via indirect DNA damage (free radicals such as reactive oxygen ...
Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
Here is why it's important to wear sunscreen to protect your skin from the harmful UV rays — not just in the summer, but all year long. What you need to know about wearing sunscreen — all year ...
The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.
A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoans.
Olive oil contains “plant compounds [that] include oleic acid, palmitic acid, linoleic acid and steric acid,” says Enright. “There are also phenolic compounds that include phytosterols ...
