Thoughts, opinions and news from Members, Fellows and Collaborators of the Society of Biology. The Society of Biology’s vision is to represent all who are committed to biology in academia, industry, education and research; to facilitate the promotion and translation of advances in biological science for national and international benefit, and to engage and encourage public interest in the life sciences.
This week, 13th-19th May, a campaign is being launched to highlight the hidden aspects of brain injury and help with the correct diagnosis of these potentially terminal conditions. The campaign is part of Action for Brain Injury (ABI) week, organised by Headway.
Brain injury is an umbrella-term for a number of conditions, including brain trauma, stroke and brain tumours. These conditions can often go unnoticed externally, yet are extremely damaging internally. It is therefore vital that GPs c........ Read more »

In the news this week has been an interesting approach to replicating human disease in a ‘lung-on-a-chip’ device. The lung-on-a-chip, which is about the size of a USB stick, contains hollow channels lined with living human cells. Applying a vacuum to two channels along the side of the chip allows it to recreate the way in which tissues physically expand and contract during respiration.... Read more »

Guest blog from Andrew Helmstetter, Savolainen Lab, Imperial College London One of the major questions that is driving research in speciation biology (the study of how new species evolve) is “why do some groups of species diversify faster than others?” The role environmental factors (e.g. climate or habitat availability) and traits (e.g. morphology, behaviour and their underlying genetics) play in controlling species diversity has been a topic of research for some time. It is unlikely that a........ Read more »

Information that individuals could use to decide whether to forage includes their own experience of performing tasks, or their own physiology such as fat reserves. This was investigated in a recent paper published in the Journal for Experimental Biology. The researchers used an ingenious system where worker ants were tagged with RFID chips which operate an artificial ‘door’ to the nest. ... Read more »
