The growth rate of the atmospheric abundance of methane (CH 4) reached a record high of 15.4 ppb yr −1 between 2020 and 2022, but the mechanisms driving the accelerated CH 4 growth have so far been ...

As former EPA and ORD scientists, we argue that dismantling ORD would not only jeopardize human and environmental health, but also weaken American science and global competitiveness. ORD’s vital—yet ...

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 ...

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

A cure for chronic hepatitis B requires eliminating or permanently silencing covalently closed circular DNA (cccDNA). A pivotal target of this approach is the hepatitis B virus (HBV) X protein (HBx), ...

The Cry proteins are pore-forming toxins produced by various strains of Bt to aid the bacteria in killing and growing on insects that happen to consume bacterial spores loaded with these crystalline ...

Circulating monocytes are recruited to the tumor microenvironment, where they can differentiate into macrophages that mediate tumor progression. To reach the tumor microenvironment, monocytes must ...

The identification of SLC35F2 as the eukaryotic transporter of queuine and queuosine is key to understanding how these micronutrients are salvaged from the human gut and distributed to different body ...
