- 			 Earth EarthFin whale songs can reveal hidden features of the ocean floorFin whale calls can penetrate into Earth’s crust, offering scientists a new way to study the properties of the ocean floor. 
- 			 Earth EarthThree things to know about the disastrous flood in IndiaThe flood, which killed at least 30 people, may have been caused by a collapsing glacier or a landslide, with climate change possibly playing a role. 
- 			 Earth EarthFossil mimics may be more common in ancient rocks than actual fossilsEvidence of early life may be harder to preserve than pseudofossils — structures that form abiotically but resemble living remnants. 
- 			 Climate ClimateShip exhaust studies overestimate cooling from pollution-altered cloudsLines of clouds formed by ship exhaust offer a window into aerosol-cloud interactions but may overestimate how much pollution-altered clouds cool the climate. 
- 			 Climate ClimateHow much will Africa capitalize on cheap renewable energy as its power grid grows?An analysis of the successes and failures of past electrical power projects across Africa suggests the continent isn’t likely to go green before 2030. 
- 			 Climate Climate‘The New Climate War’ exposes tactics of climate change ‘inactivists’In his new book, climate scientist Michael Mann draws the battle lines for a new phase of the struggle against climate change denialism. 
- 			 Climate Climate2020 and 2016 tie for the hottest years on recordOcean temperature data as well as temperatures measured over land at weather stations around the globe revealed the extent of the warming.

- 			 Paleontology PaleontologyNewborn megalodon sharks were larger than most adult humansPreserved pieces of backbone suggest that megalodon sharks were about 2 meters long at birth. 
- 			 Earth EarthReawakened Yellowstone geyser isn’t a sign of imminent explosionThe 2018 reactivation of Yellowstone’s Steamboat Geyser isn’t a portent of dangerous volcanic or hydrothermal eruptions, scientists say.
