Amazonia hosts the Earth’s largest tropical forests and has been shown to be an important
carbon sink over recent decades 1, 2, 3. This carbon sink seems to be in decline, however, as …

We present an estimate of net CO 2 exchange between the terrestrial biosphere and the
atmosphere across North America for every week in the period 2000 through 2005. This …

This study quantitatively estimates the spatial distribution of anthropogenic methane sources
in the United States by combining comprehensive atmospheric methane observations, …

Measurements of atmospheric CH 4 from air samples collected weekly at 46 remote surface
sites show that, after a decade of near‐zero growth, globally averaged atmospheric …

Tropical carbon emissions are largely derived from direct forest clearing processes. Yet,
emissions from drought-induced forest fires are, usually, not included in national-level carbon …

p63 and p73 are functionally and structurally related to the tumor suppressor p53. However,
their own role in tumor suppression is unclear. Given the p53-like properties of p63 and p73, …

Methane has the second-largest global radiative forcing impact of anthropogenic greenhouse
gases after carbon dioxide, but our understanding of the global atmospheric methane …

This paper presents a compilation of atmospheric radiocarbon for the period 1950–2019,
derived from atmospheric CO2 sampling and tree rings from clean-air sites. Following the …

Between 1999 and 2006, a plateau interrupted the otherwise continuous increase of
atmospheric methane concentration [CH 4 ] since preindustrial times. Causes could be sink …

We identified a PSEN1 (presenilin 1) mutation carrier from the world’s largest autosomal
dominant Alzheimer’s disease kindred, who did not develop mild cognitive impairment until her …
