The carbon isotopic composition of atmospheric CH 4 (δ13 C CH4) is a powerful tool for tracking the sources and sinks of atmospheric CH 4. Different CH 4 sources have distinctive δ 13 C CH4 values: ...

The steroidogenic enzyme 3β-hydroxysteroid dehydrogenase type 1 (3βHSD1) correlates with tumor aggressiveness, and its inhibitors, biochanin-A (BCA) and the related analogs, have shown antitumor ...

Crystallization of the lunar magma ocean yielded a chemically unique liquid residuum named KREEP. This component is expressed as a large patch on the near side of the Moon and a possible smaller patch ...

Heritable microbes can regulate insect reproduction in diverse ways (1). For example, some symbionts which have been called reproductive manipulators, cause cytoplasmic incompatibility, male-killing, ...

Rapid pathogen detection is crucial for effective disease management, particularly in bloodstream infections. Current molecular diagnostics often require nucleic acid preamplification, adding time and ...

We, a group of forensic scientists who have testified as expert witnesses, are not the first to point out this problem and possible solution. A landmark 2009 report from the National Research Council ...

A growing number of protein domains have been shown to undergo fold switching upon interaction with a partner, yet the mechanism remains unknown. One example is the transcriptional regulator RfaH ...

During plant growth, the demand for energy necessitates an increase in the number of chloroplasts. This increase is achieved through chloroplast division, which begins with the formation of the ...

The fishery for Antarctic krill (Euphausia superba, hereafter referred to as “krill”) is one of the world’s largest fisheries for crustaceans (1), and by far, the largest fishery in the Southern Ocean ...

Turbulence at centimeter scales plays a pivotal role in shaping the overturning circulation of the deep ocean (1, 2), as well as the ocean’s capacity to distribute and store climate-critical tracers ...
