The University of Exeter and parenting website Netmums are developing a new online therapy programme for postnatal depression.

This innovative approach to treatment has been created in response to the stigma that still surrounds postnatal depression, preventing many women from seeking help.

The research is supported by the PenCLAHRC, the National Institute for Health Research (NIHR) Peninsula Collaboration for Leadership and Applied Health Research and Care.

The research team hopes its programme will pave the way for future online treatments for depression. They are conducting this confidential study of the treatment for free and will assess its effectiveness against regular treatment. (more…)

What Do Sunsets Look Like From Other Planets?

A University of Exeter astrophysicist has shown what sunsets look like on planets outside our solar system.

He has worked out the colour of sunsets on two planets: HD 209458 b and HD 189733 b, known as ‘extrasolar planets’ because they are outside our solar system.

Extrasolar planets orbit stars, in a similar way to the Earth orbiting the Sun. Professor Frédéric Pont of the University of Exeter has used the extrasolar planets’ ‘transmission spectrum’, taken by the Hubble Space Telescope, to work out the colour of the ‘sunsets’ created by these stars.

Writing on the website ExoClimes.com, where he has posted the two sunset images he has produced, Professor Pont said: “Unlike its sister planet HD ’189, the planet HD ’209 (‘Osiris’) has a sunset that looks truly alien. The star is white outside the atmosphere, since its temperature is close to that of the Sun. It then acquires a bluish tinge as it sinks deeper, because the absorption by the broad wings of the neutral sodium lines (the spectral lines responsible for the gloomy orange of sodium street lighting) remove the red and orange from the star light.

Predators Hunt for A Balanced Diet

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.

Fit Females Make More Daughters, Mighty Males Get Grandsons

*Females influence the gender of their offspring so they inherit either their mother’s or grandfather’s qualities. ‘High-quality’ females – those which produce more offspring – are more likely to have daughters.*

*Weaker females, whose own fathers were stronger and more successful, produce more sons.*

The study, by scientists at the University of Exeter (UK), Okayama University and Kyushu University (Japan), is published today (9 January) in the journal Ecology Letters. It shows for the first time that females are able to manipulate the sex of their offspring to compensate for the fact that some of the genes which make a good male make a bad female and vice versa.

The research focuses on the broad-horned flour beetle, Gnatocerus cornutus, but the team believes the findings could apply to other species across the animal kingdom, even mammals. (more…)

What is The Real Meaning of Christmas?

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…)

*New research has found that hurricane activity is ‘clustered’ rather than random, which has important long-term implications for coastal ecosystems and human population.*

The research was carried out by Professor Peter Mumby from The University of Queensland Global Change Institute and School of Biological Sciences, Professor David Stephenson and Dr Renato Vitolo (Willis Research Fellow) at the University of Exeter’s Exeter Climate Systems research centre.

Tropical cyclones and hurricanes have a massive economic, social and ecological impact, and models of their occurrence influence many planning activities from setting insurance premiums to conservation planning. (more…)

Is Chivalry the Norm for Insects?

The long-standing consensus of why insects stick together after mating has been turned on its head by scientists from the University of Exeter.

Published in Current Biology, their study shows that, contrary to previous thinking, females benefit from this arrangement just as much as males.

Instead of dominating their female partners through bullying and aggressive behaviour, males were revealed to be protective, even laying their lives on the line when their mates faced danger.

Previously, scientists assumed that male insects stay close to females after mating to stop them from taking other partners. Female insects have multiple mates and the last mate is most likely to fertilise her eggs. Therefore, by preventing females from taking other mates a male is most likely to father her offspring.
