Cell wall mechanics and stomatal function

Although leaves may look solid, their surface is covered with microscopic pores, termed stomata. These pores play a key role in controlling how much carbon dioxide enters the plant for photosynthesis and, at the same time, how much water escapes. The pores are formed by two cells (guard cells) which swell and shrink via the control of an internal pressure called turgor. This pressure is the result of the pumping of salts into and out of the cells, leading to the flow of water into and out of the cells.

Screening art. Modernism and the socialist imaginary in East German cinema

It is tempting to dismiss the cinema of the former German Democratic Republic as nothing more than a minor episode in the history of European film production. However, during the 40 or so years of its existence, the DEFA studios in Potsdam-Babelsberg produced some 700 feature films and a huge quantity of newsreels, documentaries and films for children.

A 3D atlas of the heliosphere and solar storms

The corona, or the solar atmosphere, is a hot, magnetised plasma. At a million degree or higher, it is very hot – hot enough to almost completely ionise the gas so that it is composed of separate protons and electrons instead of neutral atoms. It is a very different environment to our atmosphere on Earth. Its structure and time evolution is dominated by the solar magnetic field. The plasma is constantly outflowing outwards into interplanetary space, and as it does so, it drags the magnetic field with it.

Dark Medicine: racism, power and the culture of American slavery

The history of human experimentation is as old as the practice of medicine and has always targeted disadvantaged, marginalised, institutionalised, stigmatised and vulnerable populations – prisoners, the condemned, orphans, the mentally ill, students, the poor, women, the disabled, children, peoples of colour, indigenous peoples and the enslaved. Dark Medicine is a research project exploring the disturbing connections between slavery, race and medicine in nineteenth-century America.

Dress, masculinities and age

It is hard to think of a group further from ideas of fashion and dress than older men. In this study I want to explore if this is, indeed, the case. It is true that older men are largely disengaged from the discourses of fashion, which they perceive negatively as being associated with women and gay men – two groups against which hegemonic masculinity is constructed. But older men too have to get dressed on a daily basis, make choices how to present themselves to the social world, respond to cultural meanings around dress and identity, and in the ways that these intersect with age.
