Unexpected Effects of Ocean Acidification on Deep-sea Organisms
About 55.5 million years ago, geologically rapid emission of a large volume of greenhouse gases at the Paleocene-Eocene boundary (PETM) led to global warming of about 5oC, severe ocean acidification, and widespread extinction of microscopic organisms living on the deep-sea floor (foraminifera).

Scientists use salt marshes to analyse global sea-level rise
The world’s salt marshes could hold the key to predicting future sea levels after scientists used them to pinpoint when recent rises began. Scientists analysed sediments and fossils buried in salt marshes which show the recent rise in global sea levels – posing a threat to millions of coastal homes worldwide – began around a century ago.

Dinosaur body shape changed the way birds stand
Scientists at the University of Liverpool and the Royal Veterinary College developed computer models of the skeletons of dinosaurs to show how body shape changed during dinosaur evolution and affected the way birds stand today. The study reveals for the first time that, contrary to popular opinion, it was the enlargement of the forelimbs over time, rather than the shortening and lightening of the tail, that led to two-legged dinosaurs gradually adopting an unusually crouched posture, with the thigh held nearly horizontally - a trait inherited by their descendants: birds.

Doubt over 'volcanic winter' after Toba super-eruption
Doubt over 'volcanic winter' after Toba super-eruption
New research from Oxford University casts doubt on the theory that the Mount Toba super-eruption, which took place at the Indonesian island of Sumatra 75,000 years ago, could have plunged the Earth into a volcanic winter leading to the near extinction of early humans. A fresh analysis of volcanic ash recovered from lake sediment cores in Lake Malawi in East Africa shows that the eruption spewed ash much further than studies have previously found.

Research explains what is cracking up Africa
Research explains what is cracking up Africa
An Imperial researcher discusses what is happening below the Earth's crust in Africa. A powerful earthquake in China's rural south-west, which measured 6.6 in magnitude, highlighted the importance of research to understand what is happening inside the Earth's rocky and often violent interior.

Multi-ethnic neighbourhoods have increased across England and Wales
Many more Whites live in mixed neighbourhoods in 2011 than 2001, according to first analyses of recently-released census data, although there was no movement towards creation of substantial Indian, Pakistani, or Bangladeshi exclusive neighbourhoods, study finds. The increased multi-ethnic composition of the population of England and Wales between 2001-2011 has been paralleled by the increased multi-ethnic character of many residential neighbourhoods, especially in London, according to new research from the University of Bristol.

Antarctica's transition to an ice world millions of years ago, revealed in study
Antarctica’s transition to an ice world millions of years ago, revealed in study
New study of sea floor core samples sheds light on how mammals and the Antarctic environment evolved in icy conditions. The emergence of mammals such as whales and penguins and the ecosystem that we are familiar with today in the seas off Antarctica can be traced back to when it was transformed into an icy world approximately 33.5 million years ago, according to research published today .

Power behind primordial soup discovered
Researchers at the University of Leeds may have solved a key puzzle about how objects from space could have kindled life on Earth. While it is generally accepted that some important ingredients for life came from meteorites bombarding the early Earth, scientists have not been able to explain how that inanimate rock transformed into the building blocks of life.

Ocean cores reveal eruption dynamics
Ocean cores reveal eruption dynamics
Using information gathered from samples of deep sea sediments, researchers from the University of Bristol report new findings regarding the dynamics of the eruption of Mount Tambora, Indonesia in 1815 - one of the largest volcanic eruptions in the last 1,000 years. Interpretation and understanding of such past eruptions are important for the assessment of hazards related to future eruptions.

Salamanders are evidence of older land connection between Central and South America
The humble salamander may provide evidence to support a controversial claim that North and South America were joined together much early than previously thought. The two continents are generally believed to have been joined together around three million years ago by the formation of a land bridge - what is now Panama - that sealed up the sea channel between them.

Scientists take to air and sea to chart progress on greenhouse gases
Scientists will use the results from the project to help gauge and track progress on Government targets to curb greenhouse gas emissions by 80% by 2050. The project will measure gases emitted from various UK sources, such as industry, landfill and agriculture. Tracking their movements will also help researchers improve their current understanding of how the gases affect climate change.

Ancient micro-continent under the Indian Ocean identified
Ancient micro-continent under the Indian Ocean identified
Scientists at the University of Liverpool have found evidence of an ancient micro-continent buried beneath the Indian Ocean. The ancient continent extends more than 1500 km in length from the Seychelles to the island of Mauritius and contains rocks as old as 2,000 million years, much older than the Indian Ocean which has formed only in the last 165 million years.

New research improves estimates of amount of ash in volcanic clouds
The amount of ash released by Iceland's Eyjafjallajökull volcano during April 2010 was significantly underestimated at the time of the eruption, according to a new model developed at the University of Bristol and published in the Journal of Geophysical Research. This could have important consequences for airspace management during future eruptions.
