Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
[6] [1] Calthemite soda straws have been recorded as growing up to 2 mm (0.079 in) per day in length, which is hundreds of times faster than speleothem soda straw growth rates typically averaging 2 mm or less per year. [4] Calthemite straws are on average just 40% the mass per unit length of speleothem straws of equivalent external diameter.
The 1,2- and 1,3- isomers have singlet ground states, whereas for 1,4-didehydrobenzene the gap is smaller. The interconversion of the 1,2-, 1,3- and 1,4-didehydrobenzenes has been studied. [ 34 ] [ 35 ] A 1,2- to 1,3-didehydrobenzene conversion has been postulated to occur in the pyrolysis (900 °C) of the phenyl substituted aryne precursors ...

Because of this, their waste products are highly acidic (approaching pH=0), with similar properties to battery acid. [2] Researchers at the University of Texas have suggested that this sulfuric acid may be a more significant cause of cave formation than the usual explanation offered of the carbonic acid formed from carbon dioxide dissolved in ...
