This Hubble image shows NGC 6984, a barred spiral galaxy some 164 million light-years away in the constellation of Indus. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. Six filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

A concentration of 2.5 μM EGCG and ECG enhanced health- and lifespan as well as stress resistance in Caenorhabditis elegans. Catechins hampered mitochondrial respiration in Caenorhabditis elegans after 6-12 hrs and the activity of complex I in isolated rodent mitochondria. The impaired mitochondrial respiration was accompanied by a transient drop in ATP production and a temporary increase in ROS levels in Caenorhabditis elegans. After 24 hrs, mitochondrial respiration and ATP levels got restored, and ROS levels even dropped below control conditions. The lifespan increases induced by EGCG and ECG were dependent on AAK-2/AMPK and SIR-2.1/SIRT1, as well as on PMK-1/p38 MAPK, SKN-1/NRF2, and DAF-16/FOXO. Long-term effects included significantly diminished fat content and enhanced SOD and CAT activities, required for the positive impact of catechins on lifespan.
