Roughly 88 % of people affected with AVM are asymptomatic ; often the malformation is discovered as part of an autopsy or during treatment of an unrelated disorder ( called in medicine " an incidental finding "); in rare cases its expansion or a micro-bleed from an AVM in the brain can cause epilepsy, deficit or pain.

Despite its toxicity, a considerable fraction of petroleum oil entering marine systems is eliminated by the hydrocarbon-degrading activities of microbial communities, in particular by a remarkable recently discovered group of specialists, the so-called hydrocarbonoclastic bacteria ( HCCB ).

He discovered a relationship between the redshift of a galaxy and its distance.

The country has not discovered sources of fossil fuels — apart from minor coal deposits — but its mountainous terrain and abundant rainfall have permitted the construction of a dozen hydroelectric power plants, making it self-sufficient in all energy needs, except oil for transportation.

After learning the rules, they discovered Judit was able to find solutions to the problems they were studying and she began to be invited into the group.

Later, other types of traversable wormholes were discovered as allowable solutions to the equations of general relativity, including a variety analyzed in a 1989 paper by Matt Visser, in which a path through the wormhole can be made where the traversing path does not pass through a region of exotic matter.

In 1818, Seebeck discovered the optical activity of the solutions of sugar.

In 1902, Norris and Kehrman independently discovered that colorless triphenylmethanol gave deep yellow solutions in concentrated sulfuric acid.

Together with Juliusz Schauder, he discovered a topological invariant, now called the Leray – Schauder degree, which they applied to prove the existence of solutions for partial differential equations lacking uniqueness.

This possibility was first raised by Kurt Gödel in 1949, who discovered a solution to the equations of general relativity ( GR ) allowing CTCs known as the Gödel metric ; and since then other GR solutions containing CTCs have been found, such as the Tipler cylinder and traversable wormholes.

The first such solutions were discovered in the case of four-dimensional Euclidean space compactified to the four-dimensional sphere, and turned out to be localized in space-time, prompting the names pseudoparticle and instanton.

In 1783 Carl Wilhelm Scheele discovered that gold dissolved in aqueous solutions of cyanide.

Over the years, various improved solutions to the maximum flow problem were discovered, notably the shortest augmenting path algorithm of Edmonds and Karp and independently Dinitz ; the blocking flow algorithm of Dinitz ; the push-relabel algorithm of Goldberg and Tarjan ; and the binary blocking flow algorithm of Goldberg and Rao.

However, the problem still remained insurmountable, until in 1953 Max Perutz discovered that the phase problem in analysis of the diffraction patterns could be solved by multiple isomorphous replacement — comparison of patterns from several crystals ; one from the native protein, and others that had been soaked in solutions of heavy metals and had metal ions introduced in different well-defined positions.

Studying instanton solutions of Yang-Mills theories ,'t Hooft discovered that spontaneously breaking a theory with SU ( N ) symmetry to a U ( 1 ) symmetry will lead to the existence of magnetic monopoles.

In support of this, Keck observations in 2007 of eight newly discovered ultra-faint Milky Way dwarf satellites showed that six were around 99. 9 % dark matter ( with a mass to light ratio of about 1000 ) Other solutions may be that dwarf galaxies tend to be gobbled up or tidally stripped apart by larger galaxies due to complex interactions.
