Muramyl dipeptide
Muramyl dipeptide (MDP), N-acetylmuramyl-L-alanyl-D-isoglutamine, is a glycopeptide and the minimal immunologically active structure of bacterial peptidoglycan, identified in 1974 as the ligand of the receptor NOD2.
Murchison meteorite
The Murchison meteorite is a carbonaceous chondrite that fell near Murchison, Victoria, Australia, in September 1969, becoming one of the most studied meteorites for its organic compounds.
Murchison Widefield Array
The Murchison Widefield Array is a low-frequency radio interferometer at the Murchison Radio-astronomy Observatory in Western Australia, operating from 80 to 300 MHz as an official Square Kilometre Array precursor since 2013.
Murnaghan equation of state
The Murnaghan equation of state is an isothermal pressure–volume relation for solids, introduced by Francis D. Murnaghan in 1944 and used to fit compression data.
Murray Gell-Mann
Murray Gell-Mann (1929–2019) was an American theoretical physicist who won the 1969 Nobel Prize in Physics for classifying subatomic particles, coined the word "quark", and co-founded the Santa Fe Institute.
Murray Gerstenhaber
Murray Gerstenhaber (died 2024) was an American mathematician at the University of Pennsylvania who founded algebraic deformation theory, discovered the Gerstenhaber algebra, and won the 2021 Steele Prize.
Murray–von Neumann classification of II₁ factors
The Murray–von Neumann classification of II₁ factors is the program begun by Murray and von Neumann in 1936 and 1943, which introduced the fundamental group invariant of a II₁ factor.
Muschelkalk
Muschelkalk, German for "bivalve limestone," is a Middle Triassic marine rock unit deposited across Central Europe for about six million years, forming the middle part of the Germanic Triassic with the Buntsandstein and Keuper.
Muscovite
Muscovite, also called white mica or Muscovy-glass, is the most common rock-forming potassium mica, occurring in schists and granites and splitting into transparent sheets valued for electrical insulation.
Musée international d'horlogerie
The Musée international d'horlogerie, also known as MIH, is a public horological museum in La Chaux-de-Fonds, Switzerland, founded in 1902 with a collection of over 10,000 timepieces.
Museo Galileo
Museo Galileo, formerly the Museo di Storia della Scienza, is a museum of the history of science in Florence, Italy, holding Galileo's surviving telescopes and the Medici instrument collections.
Musk
Musk (Moschus) is the dried glandular secretion of male musk deer, long used in medicine and perfumery; its key molecule is muscone, now replaced by synthetic musks due to CITES protection of deer.
Musselwhite mine
Musselwhite mine is an underground gold mine on Opapimiskan Lake in northwestern Ontario, about 500 km north of Thunder Bay, operating since 1997 and owned by Equinox Gold.
Mustard gas
Mustard gas, also known as sulfur mustard, is a human-made blistering chemical warfare agent first used in Flanders in 1917 that burns skin, eyes, and airways.
Mutation research
Mutation Research (Mutat. Res., ISSN 0027-5107) is an Elsevier peer-reviewed journal on mutagenesis founded in 1964, proposed by F.H. Sobels, now split into separately numbered sections including Fundamental and Molecular Mechanisms of Mutagenesis.
Mutnovsky
Mutnovsky (Мутновский) is an active basaltic complex volcano of four coalescing stratovolcanoes in southern Kamchatka, Russia, 70–80 km southwest of Petropavlovsk-Kamchatsky, with frequent phreatic eruptions, a 2000 VEI 2 event, and a geothermal power plant on its slopes.
Mutual events of Pluto and Charon
Mutual events of Pluto and Charon were eclipses and occultations from late 1984 to late 1990. The resulting light curves mapped Pluto's surface and helped discover its atmosphere.
Mutual exclusivity
Mutual exclusivity, also called disjointness, is a property of events in probability theory: mutually exclusive events cannot occur together, so their joint probability is 0 and their probabilities add.
Mutual information
Mutual information, also called transinformation, is an information theory quantity measuring how much knowing one random variable reduces uncertainty about another; it is zero exactly when the variables are independent.
Mutually orthogonal Latin squares
Mutually orthogonal Latin squares (MOLS) are sets of Latin squares in which any two superimposed give every ordered symbol pair exactly once, a combinatorial design concept.
Mutually unbiased bases
Mutually unbiased bases (MUBs) are quantum bases whose measurements are maximally complementary: certainty in one basis gives uniform outcome probabilities in another, used in tomography and cryptography.
MV-algebra
An MV-algebra, short for many-valued algebra, is an algebraic structure introduced by C. C. Chang in 1958 as the algebraic semantics of Łukasiewicz infinite-valued logic.
MWC 349
MWC 349 is a peculiar hot B[e] emission-line star in the constellation Cygnus, best known as the brightest source of strongly masing hydrogen radio recombination lines.
MXene
MXenes are a family of two-dimensional transition metal carbides, nitrides, and carbonitrides, first synthesized in 2011 at Drexel University by etching aluminum from MAX phase precursors.
MXene (Ti3C2Tx) hydrogen evolution catalysis
MXene hydrogen evolution catalysis uses the titanium carbide Ti3C2Tx as an electrocatalyst or catalyst support for the hydrogen evolution reaction, the cathodic half of water splitting.
MXene conductive hydrogels
MXene conductive hydrogels are soft, water-swollen polymer networks embedded with conductive MXene nanosheets, most often Ti₃C₂Tₓ, pairing hydrogel flexibility and biocompatibility with metallic conductivity for wearable and biomedical sensors.
MXene plasmonics
MXene plasmonics is the study and use of MXenes, two-dimensional transition-metal carbides, nitrides, and carbonitrides discovered in 2011, as plasmonic materials spanning ultraviolet to microwave wavelengths.
MXenes
MXenes are a family of two-dimensional transition metal carbides, nitrides, and carbonitrides first produced at Drexel University in 2011, applied in energy storage, shielding, and water purification.
MY Camelopardalis
MY Camelopardalis is an eclipsing contact binary of two massive O-type stars in Camelopardalis, the most massive known contact binary and a likely future merger.
