Devastating Long-Distance Impact of Earthquakes

In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today. Until now, researchers believed the earthquake was too far from the mud volcano to trigger the eruption. Geophysicists at […]

Parent Dinosaurs Shared the Work

A study into the brooding behaviour of birds has revealed their dinosaur ancestors shared the load when it came to incubation of eggs. Research into the incubation behaviour of birds suggests the type of parental care carried out by their long extinct ancestors. The study aimed to test the hypothesis that data from extant birds […]

Greening of the Earth Pushed Way Back in Time

Conventional scientific wisdom has it that plants and other creatures have only lived on land for about 500 million years, and that landscapes of the early Earth were as barren as Mars. A new study, led by geologist Gregory J. Retallack of the University of Oregon, now has presented evidence for life on land that […]

Evidence for Avian Intrathoracic Air Sacs in a New Predatory Dinosaur from Argentina

Background Living birds possess a unique heterogeneous pulmonary system composed of a rigid, dorsally-anchored lung and several compliant air sacs that operate as bellows, driving inspired air through the lung. Evidence from the fossil record for the origin and evolution of this system is extremely limited, because lungs do not fossilize and because the bellow-like […]

Geothermal Power Facility Induces Earthquakes, Study Finds

An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power, which involve pumping water into and out of an underground reservoir. “We show that the earthquake rate in the Salton Sea tracks a combination […]

Some Volcanoes ‘Scream’ at Ever Higher Pitches Until They Blow Their Tops

It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made by various types of musical instruments, though at frequencies much lower than humans can hear. A new analysis of an […]

Rare Fossils Found On Brisbane Building Site

Australian builders have uncovered a rare trove of crocodile, frog, fish and plant fossils, in what could be a world-first. The fossils relate to the period after dinosaurs died out. Pic: tenNews The fossils, trapped in a layer of oil shale, were found during excavation works near Brisbane’s Geebung railway station at a depth of […]

Rare Fossil of Late Cretaceous Plesiosaur Discovered

University of Alabama researchers have discovered the fossilized remains of a large marine reptile that once ruled the open seas 80 million years ago. The initial discovery, made June 20 by middle-school student Noah Traylor during a UA-hosted expedition, was later identified as part of a large neck vertebra of an elasmosaur, which is a […]

Scientists Cast Doubt On Theory of What Triggered Antarctic Glaciation

A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica’s ice sheet began forming. Ian Dalziel, research professor at The University of Texas at Austin’s Institute for Geophysics and professor in the Jackson School of Geosciences, and his colleagues report the findings […]

Earth’s Core Affects Length of Day

Researchers studied the variations and fluctuations in the length of day over a one to 10 year period between 1962 and 2012 Research at the University of Liverpool has found that variations in the length of day over periods of between one and 10 years are caused by processes in Earth’s core. Earth rotates once […]
