Both the frequency and intensity of droughts are forecast to increase in climate change predictions. It is well established that plant communities are sensitive to drought conditions, having implications for agriculture, forestry, and wild habitats. Despite the close association between soil fungi and plants, our understanding of how fungal communities respond to drought remains incomplete. To build this understanding, Dr Ari Jumpponen and his colleagues at Kansas State University used a combination of pure culture- and DNA-based techniques to study soil fungal communities exposed to chronic drought conditions.

The idea that human beings have souls that leave their body after death is an essential part of most religions and spiritual beliefs. However, this has been very difficult to prove scientifically. Benjamin Scherlag, Ronald Scherlag, Tarun Dasari and Sunny Po at the University of Oklahoma Health Science Centre recently investigated the existence of a soul by conducting a series of scientific studies. They carried out these experiments on a dwarf form of the organism Stentor coeruleus, which is known for its regenerative abilities.

Each year, male Western fence lizards bob, charge, and battle rivals for a chance to win mates. For many of them, tick infestations threaten to hinder their best efforts by harming the lizards’ health. But just how harmful is tick parasitism for these unfortunate lizard hosts? In their recent research, Dylan Lanser, Dr Larisa Vredevoe, and Dr Gita Kolluru at California Polytechnic State University aimed to answer this question by staging contests between tick-free and tick-infested lizards.

The genetic secrets to extraordinary longevity, superhero-like healing and regeneration, and resistance to feeding disorders could be found hidden within the Earth. In underground caves in Dinaric Karst along the Adriatic Sea in the Western Balkans lives a cave salamander, the olm, whose remarkable adaptations mean its genome holds great promise for biomedical research. Dr Rok Kostanjšek and an international team of scientists at the Proteus Genome Research Consortium are tackling the challenge of sequencing the huge olm genome, to provide the basis for studying its unique genetic characteristics.

Cell membranes are critical for life. Effectively extracting proteins with naturally associated lipids from cell membranes is necessary for research, but traditional methods may damage these membrane components and limit the accuracy of scientific data. Dr Youzhong Guo at Virginia Commonwealth University has recently developed a revolutionary method for extracting membrane components in the form of Native Cell Membrane Nanoparticles. His team’s exciting work advances our understanding of the structure, function and interactions of membrane proteins and lipids.

Arthropods – a group of invertebrates that includes insects, spiders, centipedes and woodlice – are everywhere, and have inhabited this planet for millions of years. They are found in most habitats on Earth – including our gardens and homes. It is in these built environments that a small number are considered a nuisance when sharing our ‘sacred space’. An even smaller number damage buildings or belongings, eat our food – even feed on us – so we label them… pests! Successful management of pest populations requires an understanding of their specific lifestyles and their requirements for food, water, shelter, breeding sites, and favourable temperatures. A team of entomologists at the University of Georgia recently published a guidebook of more than 100 arthropods found in and around homes in the South-eastern USA.
