Inverted fluorescence
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the study published in the journal Angewandte Chemie, such light upconversion systems could boost the light-dependent reactions for which efficiency is important, such as solar-powered water splitting.

Change in global precipitation patterns as a result of climate change
The Earth's climate system is largely determined by the differences in temperature between the tropics and the poles. Global warming is likely to cause global atmospheric circulation to change and progressively revert to a situation similar to that of 5,000 to 10,000 years ago. This is the conclusion of a study published in Nature Communications. (2020-12-17)

Errant DNA boosts immunotherapy effectiveness
DALLAS - Dec. 17, 2020 - DNA that ends up where it doesn't belong in cancer cells can unleash an immune response that makes tumors more susceptible to immunotherapy, the results of two UT Southwestern studies indicate. The findings, published online today in Cancer Cell, suggest that delivering radiation - which triggers DNA release from cells - before immunotherapy could be an effective way to fight cancers that are challenging to treat.

UV light may be a greater risk for melanoma than suspected
Studies conducted in yeast show that exposure to ultraviolet light (UV) induces new types of DNA damage that may cause the deadliest form of skin cancer, malignant melanoma. While melanoma has been associated with UV light, this study directly links UV exposure to the atypical mutations known to spread the disease. The results also indicate that UV light can induce a more diverse spectrum of mutations than previously suspected. (2020-11-17)
