Christian René Marie Joseph, Viscount de Duve (2 October 1917 – 4 May 2013) was a Nobel Prize-winning Belgian cytologist and biochemist. [2] He made serendipitous discoveries of two cell organelles, peroxisomes and lysosomes, for which he shared the Nobel Prize in Physiology or Medicine in 1974 with Albert Claude and George E. Palade ("for their discoveries concerning the structural and ...
A lysosome (/ ˈ l aɪ s ə ˌ s oʊ m /) is a single membrane-bound organelle found in many animal cells. [1] [2] They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins and its lumenal proteins.
A major piece of evidence for the presence of dark matter in the Universe, discovered by Vera Rubin from observations of galactic rotation curves in the 1970s.

Up to this time, lysosomes, discovered in the 1950s by the Belgian cytologist Christian de Duve, were thought responsible for the complete digestion of intra- and extracellular proteins by the lysosomal hydrolytic enzymes. Between the 1970s and 1980s, this view drastically changed.
“These young women discovered something that nobody else knew,” the documentary's director, David Tedeschi (who previously edited Scorsese’s Rolling Thunder Revue and George Harrison: Living ...
Overall, the data found that women with higher exposure to the forever chemical perfluorodecanoic acid (PFDE) had twice the odds of being diagnosed with melanoma, while women exposed to ...
In 1969 he gave the first clear-cut distinction between lysosomes and peroxisomes. [22] In 1972, he and his wife discovered a new type of peroxisomes from the intestinal epithelium of rat, which they named "microperoxisome". [23] [24] [12] [25]
