Ice sheets impact core elements of the Earth’s carbon cycle
The Earth's carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate. Ice sheets which cover about 10 percent of our Earth's land surface at present, were thought 20 years ago to be frozen wastelands, devoid of life and with supressed chemical weathering - irrelevant parts of the carbon cycle.

Scientists uncover deep-rooted plumbing system beneath ocean volcanoes
Cardiff University scientists have revealed the true extent of the internal 'plumbing system' that drives volcanic activity around the world. An examination of pockets of magma contained within crystals has revealed that the large chambers of molten rock which feed volcanoes can extend to over 16 km beneath the Earth's surface.

Predicting seismic activity at fracking sites to prevent earthquakes
Scientists from the University of Bristol have found a more effective way to predict seismic activity at hydraulic fracturing sites, ensuring that potential earthquake activity remains within safe levels. Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale rock by drilling down into the earth and injecting a mixture of water and sand at high-pressure, creating fractures that allow the gas or oil to flow out.

Source of new CFC emissions
Since 2013, annual emissions of a banned chlorofluorocarbon (CFC) have increased by around 7 Australia and Switzerland. Last year, it was reported that emissions of one of the most important ozone depleting substances, CFC-11, had increased. This chemical was used primarily as a foaming agent for building insulation, refrigerators and other consumer products.

Chewing versus sex in the duck-billed dinosaurs
The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 tonne giants so successful? A new study, published in Paleobiology, shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved.

Tracking the sources of plastic pollution
Plastic pollution in the world's oceans is now widely recognised as a major global challenge - but we still know very little about how these plastics are actually reaching the sea. A new global initiative, led by the University of Birmingham shows how focussing on rivers and river mouths can yield vital clues about how we might manage this plastic crisis.

Volcano cliffs can affect monitoring data
New research led by the University of East Anglia (UEA) and co-authored by the University of Bristol reveals that sharp variations of the surface of volcanoes can affect data collected by monitoring equipment. The surfaces of many volcanoes feature steep walls or cliffs. These are often part of calderas - large craters left by a previous collapse - but can also be caused by the volcano 'rifting' - or splitting - or sector collapse, when part of the side of the volcano slides away.

Prehistoric Britons rack up food miles for feasts near Stonehenge
Archaeologists have unearthed evidence of the earliest large-scale celebrations in Britain - with people and animals travelling hundreds of miles for prehistoric feasting rituals. The study, led by Dr Richard Madgwick of Cardiff University, is the most comprehensive to date and examined the bones of 131 pigs, the prime feasting animals, from four Late Neolithic (c.

Fossilised palm leaves give new insights into the geographical landscape of prehistoric central Tibet
A team of scientists from the UK and China have uncovered new evidence, using recently-discovered 25-million-year-old fossilised palm leaves, that Tibet's geography was not as 'high and dry' as previously thought. The new research, co-authored by academics from the University of Bristol's School of Geographical Sciences , suggests that central Tibet must have been no higher than 2.3km with large lakes fringed with subtropical vegetation and deep, hidden valleys.

Dinosaurs were thriving before asteroid strike that wiped them out
Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike, new research, co-authored by the University of Bristol, has found. Scientists largely agree that an asteroid impact, possibly coupled with intense volcanic activity, wiped out the dinosaurs at the end of the Cretaceous period 66 million years ago.

Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike. Scientists largely agree that an asteroid impact, possibly coupled with intense volcanic activity, wiped out the dinosaurs at the end of the Cretaceous period 66 million years ago. Dinosaurs were likely not doomed to extinction until the end of the Cretaceous, when the asteroid hit.

Diving into Earth’s interior helps scientists unravel secrets of diamond formation
Understanding the global carbon cycle provides scientists with vital clues about the planet's habitability. It's the reason why the Earth has a clement stable climate and a low carbon dioxide atmosphere compared to that of Venus, for instance, which is in a runaway greenhouse state with high surface temperatures and a thick carbon dioxide atmosphere.

Diversity on land is not higher today than in the past
The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs. According to a new study led by researchers at the University of Birmingham and involving an international team of collaborators, the number of species within ecological communities on land has increased only sporadically through geological time, with rapid increases in diversity being followed by plateaus lasting tens of millions of years.

Volcanic growth ’critical’ to the formation of Panama
It is a thin strip of land whose creation kick-started one of the most significant geological events in the past 60 million years. Yet for scientists the exact process by which the Isthmus of Panama came into being still remains largely contentious. In a new study published today in the journal Scientific Reports , scientists from Cardiff University have proposed that the Isthmus was born not solely from tectonic process, but could have also largely benefited from the growth of volcanoes.

New insights into what Neolithic people ate in southeastern Europe
New research, led by the University of Bristol, has shed new light on the eating habits of Neolithic people living in southeastern Europe using food residues from pottery extracts dating back more than 8,000 years. With the dawn of the Neolithic age, farming became established across Europe and people turned their back on aquatic resources, a food source more typical of the earlier Mesolithic period, instead preferring to eat meat and dairy products from domesticated animals.
