Scientists have discovered and documented the largest known single dinosaur track site in Alaska. The site, located in Denali National Park and Preserve, has been dubbed 'The Coliseum' by researchers.
For Decades, Our Carbon Emissions Sped the Growth of Plants — Not Anymore, Study Suggests
For the last century, rising levels of carbon dioxide helped plants grow faster, a rare silver lining in human-caused climate change.
“Planting” Rocks in Farms, Along With Emissions Reductions, Could Help Meet Key IPCC Carbon Removal Goal
Farmers around the world could help the planet reach a key carbon removal goal set by the Intergovernmental Panel on Climate Change (IPCC) by mixing crushed volcanic rocks into their fields, a new study reports.
Illinois Professor Describes How Whaling Shaped u.s. Culture Even After Petroleum Replaced It
The whaling industry helped drive industrialization in the 19th century, with whale oil used to light lamps and lubricate machinery.
Dry lightning can spark wildfires even under wetter conditions
Dry lightning can still be disastrous even when conditions aren't so dry, a study has found. These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches). A new study of...
Key role of ice age cycles in early human interbreeding
Recent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding...
Transforming flies into degradable plastics
Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the...
Even treated wastewater affects our rivers
Wastewater treatment plants are undoubtedly a great achievement. After all, they have made a significant contribution to improving the quality of natural waters. A study shows, however, that substances still manage to enter the water cycle that have an impact on the composition of the organisms living in it.
Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells
With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by...
It’s Not Just Earthquakes — Fracking Also Linked to Small Tremors, Study Finds
While past studies have linked fracking to earthquakes, scientists now say the drilling method is also a source of even small seismic tremors.
