Mapping millet genetics
In the semi-arid tropics of Asia and Africa, conditions can be difficult for crops. Plants need to have short growing seasons, survive on poor soils and tolerate environmental stresses. Enter, the millets.

Ways to reduce errors in wildlife surveys
Researchers are working to identify less error-prone methods for performing wildlife surveys.
Read moreAre humans changing animal genetic diversity worldwide?
Human population density and land use is causing changes in animal genetic diversity, according to new research. The research show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The evidence for human impacts was most clear for insects and fish species.
Read moreNew study underpins the idea of a sudden impact killing off dinosaurs and much of the other life
Fossil remains of tiny calcareous algae not only provide information about the end of the dinosaurs, but also show how the oceans recovered after the fatal asteroid impact.

Fish may be more tolerant than previously thought to periods of low oxygen in the oceans, new research shows.
Read moreClimate warming promises more frequent extreme El Niño events
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.
Read moreGenBank can be trusted, study shows
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.

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 study of Native American use of galena increases understanding of how they were using the land and its resources.

Scientists from around the world argue that the suggested afforestation of large areas of Africa to mitigate climate change will destroy valuable ecological, agricultural, and tourist areas, while doing little to reduce global CO2 levels.
