A Colorado State University experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return – at least, not for a very long time.  The study, funded by the National Science Foundation and published in Ecological Monographs, challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.   Researchers in CSU’s Warner College of Natural Resources ...

A new paper in the Quarterly Journal of Economics, published by Oxford University Press, finds that a new form of digital technology—essentially preventing people from using an asset for which they have a loan if they don’t make payments, rather than repossessing the asset itself—may be a better way for lenders to secure loans, particularly for loan recipients in developing countries. Using collateral to secure debt helps overcome economic frictions, lowering the cost of providing credit. More than 80% of total household debt in the United States is secured by ...

Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests. The insights upend theories of how black holes shape the cosmos, challenging classical understanding that they formed after the first stars and galaxies emerged. Instead, black holes might have dramatically accelerated the birth of new stars during the first 50 million years of the universe, a fleeting period within its 13.8 billion—year history. "We know these monster black holes ...

WASHINGTON, Feb. 6, 2024 – Earth’s moon achieved its Swiss cheese appearance from celestial objects crashing into its surface, forming impact craters. But craters weren’t all that was left behind; the intense pressure and temperature of such a collision also impacts the rocks and dust covering the lunar surface, known as regolith, altering its mineral composition and structure. Analyzing the resulting minerals provides modern researchers clues to the moon’s past. China’s Chang’e-5, the first lunar sample ...

Scientists have long been fascinated ...

Artificial intelligence is growing into a pivotal tool in chemical research, offering novel methods to tackle complex challenges that traditional approaches struggle with. One subtype of artificial intelligence that has seen increasing use in chemistry is machine learning, which uses algorithms and statistical models to make decisions based on data and perform tasks that it has not been explicitly programmed for. However, to make reliable predictions, machine learning also demands large amounts of data, which isn’t always available in chemical research. Small chemical datasets simply do not provide enough information for these algorithms to train on, which limits their effectiveness. In ...

In recent years, carbon-based catalysts — especially nitrogen-doped nanocarbons — have emerged as sustainable, reliable alternatives to the metal catalysts that have traditionally been used to support chemical reactions. Researchers from the Key Laboratory of Advanced Carbon-Based Functional Materials (Fujian Province University) at Fuzhou University synthesized nanocarbons from guanine molecules to better understand the precise role nitrogen plays in the carbon-based materials and explore the reaction mechanisms of these catalytic systems.   In a recently published study, the research team clarified how different types of nitrogen can modulate oxidative dehydrogenation ...
