The green sulfur bacterium makes its home in the chilly waters of the Black Sea. To eek out its lonely existence, this life form scavenges energy from the feeble sunlight available to it at a depth of over 250 feet.

A team of scientists has received US$100,000 grant to refine a mobile application (app) that uses artificial intelligence to diagnose crop diseases, and aims to help millions of African smallholders.
Global carbon dioxide emissions projected to rise after three stable years
By the end of 2017, global emissions of carbon dioxide from fossil fuels and industry are projected to rise by about 2% compared with the preceding year, with an uncertainty range between 0.8% and 3%. The news follows three years of emissions staying relatively flat.
Urban Trees are Growing Faster Worldwide
Trees in metropolitan areas have been growing faster than trees in rural areas worldwide since the 1960s. This has been confirmed for the first time by a study on the impact of the urban heat island effect on tree growth headed by the Technical University of Munich (TUM). The analysis conducted by the international research team also shows that the growth of urban trees has already been exposed to changing climatic conditions for a long period of time, which is only just beginning to happen for trees in rural areas.
York University research shows insecticide-laden seeds can disorient migrating songbirds
Songbirds exposed to widely used insecticides during migration pit stops on farmland could lose significant body weight and become disoriented, research by York University and the University of Saskatchewan (U. of S.) has found.
The researchers exposed white-crowned sparrows on spring migration to realistic doses of two different insecticides – imidacloprid, a neonicotinoid, and chlorpyrifos, an organophosphate – to see the effects on migratory activity, orientation and body mass.
Se prevé que las emisiones mundiales de dióxido de carbono aumenten después de tres años de estabilidad
Para fines de 2017, se prevé que las emisiones mundiales de dióxido de carbono procedentes de combustibles fósiles y de la industria aumentarán aproximadamente un 2% en comparación con el año anterior, con un rango de incertidumbre entre el 0,8% y el 3%. Las noticias surgen después de tres años de emisiones manteniéndose relativamente planas.
