Asteroid impacts significantly altered ancient Earth

New research shows that more than four billion years ago, the surface of Earth was heavily reprocessed as a result of giant asteroid impacts. A new model based on existing lunar and terrestrial dat...

Shrinking dinosaurs evolved into flying birds

Scientists have revealed how massive, meat-eating, ground-dwelling dinosaurs evolved into agile flying birds: they just kept shrinking and shrinking, for over 50 million years.  <img src="http:...

Antarctic ice sheet is result of carbon dioxide decrease, not continental breakup

Climate modelers have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide levels. The fi...

Tidal forces gave moon its shape early in its history, new analysis finds

The shape of the moon deviates from a simple sphere in ways that scientists have struggled to explain. A new study shows that most of the moon's overall shape can be explained by taking into accoun...

Mercury's bizzare magnetic field tells scientists how its interior is different from Earth's

Mercury's interior is different from the Earth's interior in a way that explains Mercury's bizarre magnetic field, planetary physicists report. Measurements from NASA's Messenger spacecraft have re...

Scientists caution against exploitation of deep ocean

The world's oceans are vast and deep, yet rapidly advancing technology and the quest for extracting resources from previously unreachable depths is beginning to put the deep seas on the cusp of per...

Huge waves measured for first time in Arctic Ocean

The first measurements of waves in the middle of the Arctic Ocean recorded house-sized waves during a September 2012 storm. More sensors are going out this summer to study waves in newly ice-free A...

Famine in the Horn of Africa (1984) was caused by El Nino and currents in the Indian Ocean

Oceanic patterns are important drivers of climatic variability. There is a clear link between periods of drought in the North Ethiopian Highlands and oceanic phases of El Nino, the Indian Ocean Dip...

From finding Nemo to minerals: What riches lie in the deep sea?

As fishing and the harvesting of metals, gas and oil have expanded deeper and deeper into the ocean, scientists are drawing attention to the services provided by the deep sea, the world’s largest...

Evolution in rainforest flies points to climate change survival

Scientists believe some tropical species may be able to evolve and adapt to the effects of climate change. The new findings suggests some sensitive rainforest-restricted species may survive climate...
