Experts have identified 240 Chinese cities whose emission reductions are mainly benefiting from the carbon mitigation actions of other cities, while the initial cities are putting in less effort themselves.

A physicist investigating black holes has found that, in an expanding universe, Einstein's equations require that the rate of the universe's expansion at the event horizon of every black hole must be a constant, the same ...

Across Asia, the Pacific Ocean, and the Americas, El Niño Southern Oscillation (ENSO) brings variations in winds, weather, and ocean temperature that can cause droughts, floods, crop failures, and food shortages. Recently, ...

Dark energy—a mysterious force pushing the universe apart at an ever-increasing rate—was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new warm sub-Neptune exoplanet, which is nearly three times larger than the Earth. The finding was reported ...

Macquarie University researchers have used heat to develop a simple and effective way to help endangered frogs survive the devastating impacts of a pandemic sweeping multiple species.

In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers from the University of Wisconsin–Madison found that the effects of wolves on Isle Royale have been only temporary. ...

New findings from NASA's Juno probe provide a fuller picture of how widespread the lava lakes are on Jupiter's moon Io and include first-time insights into the volcanic processes at work there. These results come courtesy ...

Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among ...
