The key to preventing asthma and reducing allergies may lie in an unexpected source: parasitic worms. Researchers at Trinity College Dublin have managed to cure experimental asthma in the lab using a live worm, the first time a human parasite has been used for this purpose. Dr Padraic Fallon from the Department of Biochemistry at Trinity College Dublin will present these findings at the BA Festival of Science on Monday 5 September.
The UK and Ireland are experiencing an asthma epidemic and have some of the highest rates of asthma in the world and the prevalence of allergic diseases has more than doubled over the last two or three decades in the developed world. This is particularly marked in Irish schoolchildren, with just under a third of children aged 13-14 showing symptoms of asthma.
‘The reasons for the dramatic recent increase in allergic diseases are complex,’ says Dr Fallon. ‘We believe a major factor is the reduction in parasitic worms, and bacterial or viral infections, in modern ‘clean’ societies. This is the often quoted: “If your kids play in dirt they will not get asthma”.’

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
