Marine heatwave events strengthen the intensity of tropical cyclones

Communications Earth & Environment
Marine heatwaves become more frequent and stronger due to global warming. It is necessary to clarify how and by which process marine heatwaves affect marine weather systems. Here, we examine how marine heatwaves strengthen tropical cyclones.

Metals strengthen with increasing temperature at extreme strain rates

Nature
The strength of materials depends on the rate at which they are tested, as defects, for example dislocations, that move in response to applied strains have intrinsic kinetic limitations1–4.

Effects of plant diversity on productivity strengthen over time due to trait-dependent shifts in species overyielding

Nature Communications
Plant diversity effects on community productivity often increase over time. Whether the strengthening of diversity effects is caused by temporal shifts in species-level overyielding (i.e., higher species-level productivity in diverse communities compared

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
