Arctic weather observations can improve hurricane track forecast accuracy
Comparison of mid-range forecast model accuracy of Atlantic hurricane tracks from 2007 to 2019 revealed that when strong winds associated with upper-level troughs caused hurricanes to move northward, track forecast accuracy was lower. The accuracy of track forecasts in such cases was improved by including data collected over the Arctic Ocean in 2017, by reducing the error in forecasting upper-level troughs. Therefore, additional data collection at high latitudes can improve mid-latitude hurricane track forecasting. (2020-10-08)

Zoologists uncover new example of rapid evolution - meet the Sulawesi Babblers
The zoologists, from Trinity College Dublin, have discovered that male and female Sulawesi Babblers (Pellorneum celebense, a species of bird) have evolved to attain different sizes on small islands, and in quick-fire time. They believe this is most likely due to evolutionary pressure favouring such ''dimorphism'' because the birds are able to reduce competition with each other by feeding on different, scarce resources.

Seeking ancient rainforests through modern mammal diets
Closed-canopy rainforests are a vital part of Earth's modern ecosystems, but tropical plants don't preserve well in the fossil record so it is difficult to tell how long these habitats have existed and where rainforests might have once grown. Instead, scientists look to the diets of extinct animals, which lock evidence of the vegetation they ate into their teeth. A new study finds that the paradigm used to identify closed-canopy rainforests needs to be reassessed. (2020-10-05)
