There are also reports of harms to health at 10 mg/m 3, for exposures of 10–15 years, but the lack of good data on past exposure levels make the association of these harms with concentrations of 10 mg/m 3 findings uncertain. The measured concentration of 10 mg/m 3 may be equivalent to a concentration in the general environment of 1 mg/m 3. [28]
BIOS-3 is an experimental closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Russia.. Its construction began in 1965, and was completed in 1972. BIOS-3 consists of a 315 cubic metres (11,100 cu ft) underground steel structure [1] suitable for up to three persons, and was initially used for developing closed ecological human life-support ecosystems.
The Crick, Brenner et al. experiment (1961) was a scientific experiment performed by Francis Crick, Sydney Brenner, Leslie Barnett and R.J. Watts-Tobin. It was a key experiment in the development of what is now known as molecular biology and led to a publication entitled "The General Nature of the Genetic Code for Proteins" and according to the historian of Science Horace Judson is "regarded ...
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

CCS can be a ligand. It can form an asymmetrical bridge between two molybdenum atoms in Mo2(μ,σ(C):η 2 (C′S)-CCS)(CO) 4 (hydrotris(3,5-dimethylpyrazol-1-yl)borate) 2 In this one carbon atom has a triple bond to a molybdenum and the other has a double bond to the other molybdenum atom, which also has a single bond to the sulfur atom.

It has been shown that carbon suboxide in an organism can quickly polymerize into macrocyclic polycarbon structures with the common formula (C 3 O 2) n (mostly (C 3 O 2) 6 and (C 3 O 2) 8), and that those macrocyclic compounds are potent inhibitors of Na + /K +-ATP-ase and Ca-dependent ATP-ase, and have digoxin-like physiological properties and ...
