New Research Casts Doubt on Theory That Volcanoes Caused Dinosaur Extinction

Scientists have new evidence in their quest to settle the longstanding debate about whether it was a gigantic meteorite or massive volcanic eruptions that triggered the mass extinction that wiped out the dinosaurs. A curious thing about the Cretaceous-Paleogene (K-Pg) mass extinction is that two apocalyptic-scale events happened at roughly the same time. Some 66…

Research confirms timing of tropical glacier melt at the end of the last ice age

Field research on glacial moraines in the Rwenzori Mountains confirms how the tropics transformed during one of Earth’s most extreme climate change events and can help current-day predictions of our own climate future.

New research into badger dispersal could minimize bovine tuberculosis spread

Credit: CC0 Public Domain Zoology researchers from Trinity, working with the Department of Agriculture, Food and The Marine (DAFM) and the National Parks and Wildlife Service (NPWS), have unlocked the secrets of dispersing badgers. Their research, reported today, has major implications for implementing vaccination programs to limit the spread of bovine tuberculosis (TB). The findings…

‘Game-changing’ research could solve evolution mysteries

A Stephanorhinus skull from Dmanisi. Credit: Mirian Kiladze, Georgian National Museum An evolution revolution has begun after scientists extracted genetic information from a 1.7 million-year-old rhino tooth—the largest and oldest genetic data to ever be recorded. Researchers identified an almost complete set of proteins, a proteome, in the dental enamel of the rhino and the…

Research sheds new light on Antarctic control of global climate

Sea ice and icebergs in the shelf sea environment adjacent to Antarctica. Credit: Mike Meredith, British Antarctic Survey Scientists have made a new discovery that challenges previous understanding of the relationship between the polar Southern Ocean, next to Antarctica, and carbon dioxide levels in the atmosphere. Their findings show that, contrary to existing assumptions, biological…

Research: Climate change helped elephants evolve a large brain

Elephants have long captivated our attention, partly because of their sheer size and majesty. But we’re also struck by their complex behavior. In some ways, we’re fascinated because this behavior echoes our most humane feelings. For instance, elephants have repeatedly been observed using tools and grieving their dead. Their evolutionary history is interesting, too. It…
