Actions on sustainable food production and consumption for the post-2020 global biodiversity framework
(Journal article; Peer reviewed, 2021)Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 ... -
Arctic Ocean Amplification in a warming climate in CMIP6 models
(Journal article; Peer reviewed, 2022)Arctic near-surface air temperature warms much faster than the global average, a phenomenon known as Arctic Amplification. The change of the underlying Arctic Ocean could influence climate through its interaction with sea ... -
Atmospheric circulation over Europe during the Younger Dryas
(Journal article; Peer reviewed, 2020)The Younger Dryas (YD) was a period of rapid climate cooling that occurred at the end of the last glaciation. Here, we present the first palaeoglacier-derived reconstruction of YD precipitation across Europe, determined ... -
A bending rigidity parameter for stress granule condensates
(Journal article; Peer reviewed, 2023)Interfacial tension plays an important role in governing the dynamics of droplet coalescence and determining how condensates interact with and deform lipid membranes and biological filaments. We demonstrate that an interfacial ... -
Cell identity and nucleo-mitochondrial genetic context modulate OXPHOS performance and determine somatic heteroplasmy dynamics
(Journal article; Peer reviewed, 2020)Heteroplasmy, multiple variants of mitochondrial DNA (mtDNA) in the same cytoplasm, may be naturally generated by mutations but is counteracted by a genetic mtDNA bottleneck during oocyte development. Engineered heteroplasmic ... -
Chlamydial contribution to anaerobic metabolism during eukaryotic evolution
(Journal article; Peer reviewed, 2020)The origin of eukaryotes is a major open question in evolutionary biology. Multiple hypotheses posit that eukaryotes likely evolved from a syntrophic relationship between an archaeon and an alphaproteobacterium based on ... -
Early human impacts and ecosystem reorganization in southern-central Africa
(Journal article; Peer reviewed, 2021-05-05)Modern Homo sapiens engage in substantial ecosystem modification, but it is difficult to detect the origins or early consequences of these behaviors. Archaeological, geochronological, geomorphological, and paleoenvironmental ... -
Earthquakes track subduction fluids from slab source to mantle wedge sink
(Peer reviewed; Journal article, 2019)Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ... -
An ecological niche shift for Neanderthal populations in Western Europe 70,000 years ago
(Journal article; Peer reviewed, 2021)Middle Paleolithic Neanderthal populations occupied Eurasia for at least 250,000 years prior to the arrival of anatomically modern humans. While a considerable body of archaeological research has focused on Neanderthal ... -
Evolution of vegetation and climate variability on the Tibetan Plateau over the past 1.74 million years
(Journal article; Peer reviewed, 2020)The Tibetan Plateau exerts a major influence on Asian climate, but its long-term environmental history remains largely unknown. We present a detailed record of vegetation and climate changes over the past 1.74 million years ... -
GADL1 is a multifunctional decarboxylase with tissue-specific roles in β-alanine and carnosine production
(Journal article; Peer reviewed, 2020)Carnosine and related β-alanine–containing peptides are believed to be important antioxidants, pH buffers, and neuromodulators. However, their biosynthetic routes and therapeutic potential are still being debated. This ... -
How is a turbidite actually deposited?
(Journal article; Peer reviewed, 2022)The deposition of a classic turbidite by a surge-type turbidity current, as envisaged by conceptual models, is widely considered a discrete event of continuous sediment accumulation at a falling rate by the gradually waning ... -
Human footprints provide snapshot of last interglacial ecology in the Arabian interior
(Journal article; Peer reviewed, 2020)The nature of human dispersals out of Africa has remained elusive because of the poor resolution of paleoecological data in direct association with remains of the earliest non-African people. Here, we report hominin and ... -
Insm1-expressing neurons and secretory cells develop from a common pool of progenitors in the sea anemone Nematostella vectensis
(Journal article; Peer reviewed, 2022)Neurons are highly specialized cells present in nearly all animals, but their evolutionary origin and relationship to other cell types are not well understood. We use here the sea anemone Nematostella vectensis as a model ... -
Lake sediments with Azorean tephra reveal ice-free conditions on coastal northwest Spitsbergen during the Last Glacial Maximum
(Peer reviewed; Journal article, 2019-10-23)Lake sediments retrieved from the beds of former nonerosive ice sheets offer unique possibilities to constrain changes in the extent and style of past glaciation, and place them in an absolutely dated context. We present ... -
Light penetration structures the deep acoustic scattering layers in the global ocean
(Peer reviewed; Journal article, 2017)The deep scattering layer (DSL) is a ubiquitous acoustic signature found across all oceans and arguably the dominant feature structuring the pelagic open ocean ecosystem. It is formed by mesopelagic fishes and pelagic ... -
Mechanism of actin N-terminal acetylation
(Journal article; Peer reviewed, 2020)About 80% of human proteins are amino-terminally acetylated (Nt-acetylated) by one of seven Nt-acetyltransferases (NATs). Actin, the most abundant protein in the cytoplasm, has its own dedicated NAT, NAA80, which acts ... -
Models with higher effective dimensions tend to produce more uncertain estimates
(Journal article; Peer reviewed, 2022)Mathematical models are getting increasingly detailed to better predict phenomena or gain more accurate insights into the dynamics of a system of interest, even when there are no validation or training data available. Here, ... -
North Atlantic Oscillation in winter is largely insensitive to autumn Barents-Kara sea ice variability
(Journal article; Peer reviewed, 2021)Arctic sea ice extent in autumn is significantly correlated with the winter North Atlantic Oscillation (NAO) in the satellite era. However, questions about the robustness and reproducibility of the relationship persist. ... -
North Atlantic surface ocean warming and salinization in response to middle Eocene greenhouse warming
(Journal article; Peer reviewed, 2023)Quantitative reconstructions of hydrological change during ancient greenhouse warming events provide valuable insight into warmer-than-modern hydrological cycles but are limited by paleoclimate proxy uncertainties. We ...
