Open AccessDecreased left atrial function in obesity patients without known cardiovascular disease
Obesity is a risk factor for heart failure with preserved ejection fraction (HFpEF). We hypothesized that assessment of left atrial (LA) strain may be useful to reveal precursors of HFpEF in obesity patients. ...

Deep Atlantic Ocean carbon storage and the rise of 100,000-year glacial cycles
Over the past three million years, Earth’s climate oscillated between warmer interglacials with reduced terrestrial ice volume and cooler glacials with expanded polar ice sheets. These climate cycles, as refle...

Space–time control of free induction decay in the extreme ultraviolet
Ultrafast extreme-ultraviolet (XUV) and X-ray sources are revolutionizing our ability to follow femtosecond processes with ångström-scale resolution. The next frontier is to simultaneously control the directio...

Open AccessMadagascar corals track sea surface temperature variability in the Agulhas Current core region over the past 334 years
The Agulhas Current (AC) is the strongest western boundary current in the Southern Hemisphere and is key for weather and climate patterns, both regionally and globally. Its heat transfer into both the midlatit...

Open AccessEfficient high-order harmonic generation boosted by below-threshold harmonics
High-order harmonic generation (HHG) in gases has been established as an important technique for the generation of coherent extreme ultraviolet (XUV) pulses at ultrashort time scales. Its main drawback, howeve...

Open AccessExploring high-end scenarios for local sea level rise to develop flood protection strategies for a low-lying delta—the Netherlands as an example
Sea level rise, especially combined with possible changes in storm surges and increased river discharge resulting from climate change, poses a major threat in low-lying river deltas. In this study we focus on ...

Palaeoceanographic implications of genetic variation in living North Atlantic Neogloboquadrina pachyderma
The shells of the planktonic foraminifer Neogloboquadrina pachyderma have become a classical tool for reconstructing glacial–interglacial climate conditions in the North Atlantic Ocean1,2,3. Palaeoceanographers u...
