Researchers recently unveiled their discovery of a new process for making RNA. The resulting RNA is purer, more copious and likely to be more cost-effective than any previous process could manage. This new technique removes the largest stumbling block on the path to next-generation RNA therapeutic drugs.

Two new molecules that generate minute amounts of the gas hydrogen sulfide have been found to prevent skin from aging after being exposed to ultraviolet light found in sunlight. Sunburn is a major cause of premature aging in skin, and a primary risk factor for skin cancer, and other skin problems associated with aging. Now, an international research team has made inroads towards being able to reverse or delay this damage for the first time.

Last year, researchers reported that reductive stress -- an imbalance in the normal oxidation/reduction homeostasis -- caused pathological changes associated with heart failure in a mouse model. Now, researchers describe the putative molecular regulators of this pathological chronic reductive stress -- a microRNA network.
