Climate change causes landfalling hurricanes to stay stronger for longer

Climate change is causing hurricanes that make landfall to take more time to weaken, reports a new study. Researchers showed that hurricanes that develop over warmer oceans carry more moisture and therefore stay stronger for longer after hitting land. This means that in the future, as the world continues to warm, hurricanes are more likely to reach communities farther inland and be more destructive.

Large, delayed outbreaks of endemic diseases possible following COVID-19 controls

Measures such as mask wearing and social distancing that are key to reducing coronavirus infection have also greatly reduced the incidence of other diseases, such as influenza and respiratory syncytial virus (RSV). But researchers report that current reductions in these common respiratory infections, however, may increase people's susceptibility to these diseases, resulting in large future outbreaks when they begin circulating again.

Paleontologists have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed 'Fabian', was discovered in 2015 at the Frick fossil site in Switzerland.
