Researchers at the University of Warwick and University College London have found that lack of sleep can more than double the risk of death from cardiovascular disease, but that too much sleep can also be associated with a doubling of the risk of death, though not primarily from cardiovascular disease.

Researchers are also interested in proteins that can fold into more than one stable configuration ; protein aggregation diseases such as Alzheimer's Disease and Huntington's Disease as well as prion diseases such as Mad Cow disease can be better understood by constructing ( and deconstructing ) disease models ; the most common way of doing this is by developing a way of inducing the desired disease state in test animals ( administering MPTP to give the animals Parkinson's disease, or knocking out a gene essential for the prevention of certain tumors from the animals ' genomes ).

Guenon also wrote that Blavatsky had borrowed passages taken from a translation of extracts from the Kanjur and Tanjur published in 1836 in the twentieth volume of the Asiatic Researchers of Calcutta by Sándor Kőrösi Csoma an eccentric orientalist.
