A new study cross-examines classic hypotheses about the coevolution of butterflies with flowering plants and moths with bats, their key predators. The findings show flowering plants did drive much of these insects' diversity, but in a surprise twist, multiple moth lineages evolved 'ears' millions of years before the existence of bats, previously credited with triggering moths' development of hearing organs.

Scientists working to identify coral reef organisms analyzed more than 4.7 million animal DNA sequences from GenBank, the most commonly used tool used to identify environmental DNA, and discovered that animal identification errors are surprisingly rare -- but sometimes very funny.

New research, based on 33 historical El Niño events from 1901 to 2017, show climate change effects have shifted the El Niño onset location from the eastern Pacific to the western Pacific and caused more frequent extreme El Niño events since the 1970's. Continued warming over the western Pacific warm pool, driven by anthropogenic climate change, promises conditions that will trigger more extreme events in the future.

A new study finds that the western South Atlantic humpback population has grown to 25,000 whales. Researchers believe this new estimate is now close to pre-whaling numbers.

A new octocoral species was recently discovered in a biodiversity hotspot and World Heritage Site in Pacific Panama. It inhabits an unexplored and understudied marine ecosystem, under increasing need for protection: the mesophotic coral communities.

The transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.

Despite an overall increase in the number of pharmacies in the U.S. from 2009 to 2015, one in eight pharmacies, or 9,654, had closed during this period. Independent pharmacies in both urban and rural areas were three times more likely to close than chain pharmacies.
