Museums use taxidermy as a method to record species, including those that are extinct and threatened, [5] in the form of study skins and life-size mounts. Taxidermy is sometimes also used as a means to memorialize pets. [6] A person who practices taxidermy is called a taxidermist.
It works like a charm! It can be incredibly heartbreaking for pet parents to watch their dogs suffer from separation anxiety.
A crash test dummy, or simply dummy, is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision.

Alderson (October 21, 1914 – February 11, 2005) was an American inventor best known for his development of the crash test dummy, a device that, during the last half of the twentieth century, was widely used by automobile manufacturers to test the reliability of automobile seat belts and other safety protocols.
The possible role of liquid ammonia as an alternative solvent for life is an idea that goes back at least to 1954, when J. B. S. Haldane raised the topic at a symposium about life's origin.

A dry lab is a laboratory where the nature of the experiments does not involve significant risk. This is in contrast to a wet lab where it is necessary to handle various types of chemicals and biological hazards.
Paley's method could be used to find such matrices of size N for most N equal to a multiple of 4. In particular, it worked for all such N up to 100 except N = 92. If N is a power of 2, however, the resulting design is identical to a fractional factorial design , so Plackett–Burman designs are mostly used when N is a multiple of 4 but not a ...
