New study exposes negative effects of climate change on Antarctic fish

Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps).

Plant light sensors came from ancient algae

The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow were inherited millions of years ago from ancient algae, finds a new study from Duke University.

Abrupt climate change may have rocked the cradle of civilisation

New research reveals that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These findings show that while socio-economic factors were traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should

What killed off the megafauna?

Rapid phases of warming climate played a greater role in the extinction of megafauna in the Late Pleistocene than did human activity, a new study shows.

Mammoths killed by abrupt climate change

New research has revealed abrupt warming, that closely resembles the rapid man-made warming occurring today, has repeatedly played a key role in mass extinction events of large animals, the megafauna, in Earth’s past.

Plate tectonics may have driven the evolution of life on Earth

When Charles Darwin published his theory of evolution by natural selection in 1859, the world hadn’t even heard of plate tectonics. The notion that continents drifted on molten rock currents deep in the Earth’s mantle was unimaginable.

New Ice Age may begin by 2030

The arrival of intense cold similar to the one raged during the “Little Ice Age”, which froze the world during the XVII century and in the beginning of the XVIII century, is expected in the years 2030–2040.

How the mammoth got its wool: Genetic changes are identified

Evolutionary change in a gene resurrected in the lab from the extinct woolly mammoth altered the gene’s temperature sensitivity and likely was part of a suite of adaptations that allowed the mammoth to survive in harsh arctic environments, according to new research.

Unveiling the ancient climate of Mars

The high seas of Mars may never have existed. According to a new study that looks at two opposite climate scenarios of early Mars, a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the planet today.

What rabbits can tell us about Neanderthal extinction?

When thinking about the extinction of Neanderthals some 30,000 years ago, rabbits may not be the first thing that spring to mind. But the way rabbits were hunted and eaten by Neanderthals and modern humans – or not, as the case may be – may offer vital clues as to why one species died out while the other flourished.
