Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of...

Frisch named the process "fission" by analogy with biological fission of living cells. In their second publication on nuclear fission in February 1939, Hahn...

Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the...

Schizosaccharomyces pombe, also called "fission yeast", is a species of yeast used in traditional brewing and as a model organism in molecular and cell...

Biological immortality (sometimes referred to as bio-indefinite mortality) is a state in which the rate of mortality from senescence (or aging) is stable...

Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a...

and archaea) usually undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells...

Modern fusion weapons essentially consist of two main components: a nuclear fission primary stage (fueled by 235 U or 239 Pu ) and a separate nuclear fusion...

Strontium-90 (90 Sr ) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90...

Biological databases are libraries of biological sciences, collected from scientific experiments, published literature, high-throughput experiment technology...

by spontaneous fission of uranium and thorium present in crustal minerals. The neutron background is not strong enough to be a biological hazard, but it...

A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans....

fertile material in turn transmutes into fissile material which can undergo fission reactions. Breeders were at first found attractive because they made more...
