Earliest documentation of fossil ciliate protozoans

The world’s earliest known fossil ciliate protozoans were formally documented in 2007. These ‘hairy’ microscopic single-celled organisms, characterised by tiny hair-like structures known as cilia on their external surface, were discovered within the Doushantuo Formation – a fossil-rich sedimentary deposit in China’s Guizhou Province, dating back approximately 580 million years to the Ediacaran Period.

Desert plant with the longest leaves

The wonder plant (Welwitschia mirabilis) of the Namib Desert in Namibia and Angola only produces two leaves, but they are far longer than those of any other species of desert plant, each one growing between 2-4 m long, though they eventually become split, or at least become shredded at their tips, due to the arid desert winds and harsh living conditions experienced in this environment. In contrast, the leaves of other desert plants are usually very small, to prevent water loss via evaporation.

English National Championships (Tiddlywinks)

Larry Kahn (USA) has won the English Tiddlywinks Association’s (ETwA) National Championships singles title a record eight times, between 1984 and 2010. Jonathan Mapley (UK) has won the ETwA’s National Championships pairs title an unprecedented nine times, between 1972 and 2000. Note from Patrick Barrie: ETwA (English Tiddlywinks Association) and NATwA (North American Tiddlywinks Association) host the “major” tiddlywinks tournaments (as defined by the International Federations of Tiddlywinks Associations). Tiddlywinks may be played as a “singles” game or as a “pairs” game (much like tennis Continue reading →
