[168] This was due to a stark 60-kilometre-per-hour (37 mph) wind that distributed ryegrass pollen into the moist air, rupturing them into very fine specks small enough to enter people's lungs.
Terminal lucidity (also known as rallying, terminal rally, the rally, end-of-life-experience, energy surge, the surge, or pre-mortem surge) [1] is an unexpected return of consciousness, mental clarity or memory shortly before death in individuals with severe psychiatric or neurological disorders.
The most famous members are from the genus Arthropleura, which was a giant, probably herbivorous, animal that could be up to 2.63 metres (8 ft 8 in) long, [34] but the group also includes species less than 1 cm (0.39 in). Arthropleuridea was historically considered a distinct class of myriapods, but since 2000 scientific consensus has viewed ...
Due to their intelligence, cephalopods are commonly protected by animal testing regulations that do not usually apply to invertebrates. In the UK from 1993 to 2012, the common octopus ( Octopus vulgaris ) was the only invertebrate protected under the Animals (Scientific Procedures) Act 1986 . [ 48 ]
