A tidbit about ocean acidification that recalls chemistry and biology classes — with concerning effect 0

Citation Robert F. Service, Rising Acidity Brings an Ocean of Trouble, Science 337(6091): 146-148 (13 July 2012) In oceans — a pH drop from 8.2 to 8.1 appears to be a very big deal for some important critters That’s a 30 percent increase in oceanic acidity from before the Industrial Revolution to the present. Even [...]

Chrysanthemums adapt to irregular lighting patterns that disrupt their normal circadian rhythm — and, if cumulative light duration is short, they grow faster to compensate 0

Interesting, for those of us who wondered how erratic interior lighting affects plants Katrine Heinsvig Kjaer and Carl-Otto Ottosen were curious about plant growth under greenhouse conditions in which northern hemisphere growers turned grow lights on during off-peak electricity times and off during more costly peak periods: Leaf expansion and stem elongation occurred at a [...]

Ocean water color change can now be used to track the Pacific’s equatorial warm pool, helping scientists more accurately predict El Niño Southern Oscillation weather effects 0

Ocean water color change can now be used to track the Pacific’s equatorial warm pool, helping scientists more accurately predict El Niño Southern Oscillation weather effects Water’s chlorophyll content is the key The Pacific Ocean’s equatorial warm pool is characterized by comparatively higher temperatures, reduced salinity (due to rainfall), and diminished life.  None of these [...]
