We show that 85% of variation in total organic carbon can be explained by mineral surface
area in a black shale deposit from two locations in the late Cretaceous Western Interior …

Liability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic
architecture or its genetic relationship with other disorders. To discover loci associated …

Many aspects of the carbon cycle can be assessed from temporal changes in the 13 C/ 12 C
ratio of oceanic bicarbonate. C/ 12 C can temporarily rise when large amounts of 13 C-…

A thick Neoproterozoic carbonate and glaciogenic succession of the southern Congo craton
has yielded δ 13 C and 87 Sr/ 86 Sr records through the later Cryogenian (ca. 750–600 Ma) …

The Earth's most severe glaciations are thought to have occurred about 600 million years
ago, in the late Neoproterozoic era 1 , 2 . A puzzling feature of glacial deposits from this …

Regionally persistent, thin intervals of carbonate rock directly and ubiquitously overlie
Proterozoic glacial deposits on almost every continent, and are commonly referred to as cap …

Background Variation in liability to cannabis use disorder has a strong genetic component (estimated
twin and family heritability about 50–70%) and is associated with negative …

Thin (< 15 m) laterally persistent carbonate units cap glacial deposits in Neoproterozoic
successions (1000-544 Ma) on almost every continent. Because these enigmatic carbonate …

Two distinctive volcanic ash beds were found in the terminal Proterozoic Doushantuo Formation
in south China. The lower ash bed, ∼2.5 m above the cap carbonate at the base of the …

The Neoproterozoic contains severe glacial intervals (750–580 Ma) including two extending
to low palaeomagnetic latitudes. Paucity of radiometric dates indicates the need for …
