Predators select their prey in order to eat a nutritionally balanced diet and give themselves the best chance of producing healthy offspring.

A University of Exeter and Oxford-led study published in Proceedings of the Royal Society B shows for the first time that predatory animals choose their food on the basis of its nutritional value, rather than just overall calorie content.

An international team of scientists from the Universities of Exeter and Oxford in the UK, University of Sydney (Australia), Aarhus University (Denmark) and Massey University (New Zealand) based their research on the ground beetle, Anchomenus dorsalis, a well-known garden insect that feasts on slugs, aphids, moths, beetle larvae and ants.

There are thousands of stories in the Bible and a visual artist in Exeter is currently on a 30-year mission to paint the whole lot.

The University of Exeter is incorporating some of what will eventually be a series of up to 3,000 artworks by Brian J Turner into new school curriculum resources that explore how biblical stories are read and interpreted.

The Art of Narrative Theology in Religious Education project is being led by Drs Esther Reed and Rob Freathy from the Department of Theology and Religion and the Graduate School of Education at the University of Exeter. The aim of the project is to get school pupils to investigate biblical stories and how people, whether from a Christian background or not, interpret and use them to make sense of their world and their role within it, particularly how they can live a good life.

A key mechanism by which a bacterial pathogen causes the deadly tropical disease melioidosis has been discovered by an international team, including a University of Exeter scientist.

The findings are published in the journal Science and show how a toxin produced by the bacterium Burkholderia pseudomallei kills cells by preventing protein synthesis.

The study, led by the University of Sheffield, paves the way for the development of novel therapies to combat the bacterium which infects millions of people across South East Asia and Northern Australia.

Using intense X-rays at Diamond Light Source, the UK’s national synchrotron facility, and at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, the research team solved the structure of a protein from Burkholderia, the function of which was initially unknown. (more…)

‘Heat-proof’ Eggs Help Turtles Cope With Hot Beaches

*Sea turtles face an uncertain future as a warming climate threatens to reduce their reproductive viability.*

*However, new research led by the University of Exeter and published this week in Proceedings of the Royal Society B shows that some turtles are naturally heat-tolerant.*

The study focused on green turtles nesting on Ascension Island, a UK overseas territory in the South Atlantic Ocean. Scientists from the Universities of Exeter and Groningen found that eggs laid by turtles nesting on a naturally hot beach withstand high temperatures better than eggs from turtles nesting on a cooler beach just a few kilometres away.

A University of Exeter archaeologist’s research has uncovered the largest Roman settlement ever found in Devon. The discovery could force us to rewrite the history of the Romans in Britain.

The discovery of a large Roman Settlement in Devon was the result of a chance metal detecting coin find. Danielle Wootton, the Finds Liaison Officer for the Portable Antiquities Scheme (PAS) and archaeologist at the University of Exeter was called on to investigate further. (more…)

The three-part documentary, presented by journalist Rageh Omaar, charts the story of the Prophet who, in little more than 20 years, changed the world forever.*

Professor Sajjad Rizvi, University of Exeter’s Associate Professor of Islamic Intellectual History at the Institute of Arab and Islamic Studies, provided expert advice to the BBC team. He also appears in the series. (more…)

Decline in Species Shows Climate Change Warnings Not Exaggerated

One in 10 species could face extinction by the year 2100 if current climate change impacts continue.

This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.

Published in leading journal Proceedings of the National Academy of Sciences, the study uses the well-established IUCN Red List for linking population declines to extinction risk. The research examines nearly 200 predictions of the future effects of climate change from studies conducted around the world, as well as 130 reports of changes which have already occurred. (more…)

*A University of Exeter biologist has discovered a ‘lost’ species of bat breeding on the Isles of Scilly.*

*A pregnant female brown long-eared bat is the first of its species to be found on the islands for at least 40 years.*

It was discovered by Dr Fiona Mathews, Senior Lecturer at the University of Exeter, a postgraduate student and a team from the Wiltshire Bat Group.

The Scilly Isles Bat Group called in Dr Mathews and her team to help them find out more about bats on the islands. The researchers set up a radiotracking study, with funding from the Isles of Scilly Area of Outstanding Natural Beauty, to monitor the islands’ bat activity. (more…)
