He used his position to denounce biologists as "fly-lovers and people haters", [19] and to decry traditional biologists as "wreckers" working to sabotage the Soviet economy. He denied the distinction between theoretical and applied biology , and rejected general methods such as control groups and statistics: [ 20 ]
According to The Atlantic writer Sam Kean, "Lysenko gutted it, and by some accounts, set Russian biology and agronomy back a half-century". [9] Lysenko's work was eventually recognized as fraudulent by some, "but not before he had wrecked the lives of many and destroyed the reputation of Russian biology" according to scientist Peter Gluckman.

Diplosentis amphacanthi Tubangui & Masilungan, 1937 [1] D. amphacanthi was collected in the Philippines exclusively from the White-spotted spinefoot (Siganus canaliculatus but reported as the synonym Amphacanthus oramin) which occurs widely in the tropical Indo-Pacific. [7] It is the type species. [3] It was specifically found in Mindanao. [8]
Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.
Thomas began writing a monthly essay “Notes of a Biology Watcher” in the New England Journal of Medicine in 1971 while he was at Yale. In 1973 he became the president of the Sloan-Kettering Institute in New York. Lewis Thomas published multiple books throughout his career, the first being The Lives of a Cell: Notes of a Biology Watcher.
A life history strategy is the "age- and stage-specific patterns" [2] and timing of events that make up an organism's life, such as birth, weaning, maturation, death, etc. [3] These events, notably juvenile development, age of sexual maturity, first reproduction, number of offspring and level of parental investment, senescence and death, depend ...
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
Steps of the cell cycle. The restriction point occurs between the G 1 and S phases of interphase.. The restriction point (R), also known as the Start or G 1 /S checkpoint, is a cell cycle checkpoint in the G 1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation.
