The Middle East and North Africa Region (MENA) is a climate change hot spot where summers warm much faster than in the rest of the world. Some parts of the region are already among the hottest locations globally. A new international study predicts that ignoring the signals of climate change and continuing business-as-usual will lead to extreme and life-threatening heatwaves in the region. Such extraordinary heat events will have a severe impact on the people of the area.

Our planet's worst mass extinction event happened 252 million years ago when massive volcanic eruptions caused catastrophic climate change. The vast majority of animal species went extinct, and when the dust settled, the planet entered the early days of the Age of Dinosaurs. Scientists are still learning about the patterns of which animals went extinct and which ones survived, and why. In a new study in PNAS, researchers found that while extinctions happened rapidly in the oceans, life on land […]

Likely the first extinction event of the 2000s in Europe, the sad history of the Pyrenean Ibex (Capra pyrenaica pyrenaica) is a powerful example of the ever-increasing species loss worldwide due to causes related to human activity. It can, however, give us valuable information on what should be done (or avoided) to halt this extinction vortex.

A University of New Mexico Biology professor and second-year Ph.D. student are part of a team of scientists who have examined the immune system of an unusual group of mammals, which includes a small South American opossum, to find solutions that evolution has produced to fight disease-causing pathogens.

Scientific evidence shows specialized features in the large brains of whales and dolphins that are adapted for heat production.
