Pelagibacter ubique is one of the smallest known free-living bacteria, with a length of 370 to 890 nm (0.00037 to 0.00089 mm) and an average cell diameter of 120 to 200 nm (0.00012 to 0.00020 mm). They also have the smallest free-living bacterium genome: 1.3 Mbp, 1354 protein genes, 35 RNA genes. They are one of the most common and smallest ...
The book has been published in a limited edition of 100 copies by the laboratory and requires a scanning electron microscope to read the text. In December 2012, a Library Edition of the book was published with a full title of Teeny Ted from Turnip Town & the Tale of Scale: A Scientific Book of Word Puzzles and an ISBN 978-1-894897-36-5 .
The Guinness Book of World Records lists the frog's body weight at 10 milligrams (0.00035 oz), [13] while measurements of Schindleria brevipinguis show them to weigh less than 2 milligrams (7.1 × 10 −5 oz), with one adult specimen weighing just 0.7 milligrams. [14] The frog lives on land and its life cycle does not include a tadpole stage. [11]
The bee hummingbird has also been described as the smallest dinosaur. [7] This characterization is based upon the recognition that birds are, in fact, a living form of theropod dinosaurs (or, strictly speaking, avian dinosaurs ), [ 8 ] and no smaller bird or non-avian dinosaur has been found in the fossil record.
The synthetic cell is called: Mycoplasma mycoides JCVI-syn1.0. The DNA was designed in a computer, synthesized, and transplanted into a cell from which the original genome had been removed. The original molecules and on-going reaction networks of the recipient cell then used the artificial DNA to generate daughter cells.
Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
It is a living organism (contains DNA or some analogue, and reproduces).; Has a morphology similar to Actinomycetes and fungi.; Nanobes are about 20 nm in diameter, which may be too small to contain the basic elements for an organism to exist (DNA, ribosomes, etc.), suggesting that if they grow and reproduce they would need to do so in an unconventional way.
Lewis Thomas published multiple books throughout his career, the first being The Lives of a Cell: Notes of a Biology Watcher. In 1979 he published The Medusa and the Snail: More Notes of a Biology Watcher. He wrote an autobiographical book in 1983, The Youngest Science: Notes of a Medicine-Watcher.
