Trypanosomes are single-celled parasites that cause life-threatening diseases in humans, domestic livestock and wild animals. In sub-Saharan Africa, infection with a species called Trypanosoma brucei or T.brucei causes African sleeping sickness, which results in organ failure and eventually fatal coma if left untreated. There are limited diagnostic tests and treatments available and much of trypanosome biology remains undiscovered.

Covalent drugs are molecules that irreversibly bind to specific, targeted sites in the body. They work to inhibit the disease-causing functions of certain proteins by preventing them from interacting with other substances. One well-known example is the antibiotic, Penicillin.

Myopia – better known as short-sightedness – is a global health problem in which the eye grows too long, meaning it cannot produce clear images of objects in the distance. The common form of myopia is readily treated through the wearing of glasses, contact lenses or conducting laser surgery. It is also polygenic, meaning that many genes are likely to be involved in its inheritance through generations.

Tetanus is a serious, potentially fatal disease of the nervous system caused by Clostridium tetani bacteria entering the body. It is characterised by severe stiffness, muscle spasms and breathing difficulties. In some developing countries, tetanus unfortunately still occurs and presents a significant healthcare challenge, particularly in relation to maternal and neonatal (newborn) deaths.

Chemical intolerance is on the rise, currently afflicting around 20% of the American population. Common triggers include low-level exposure to indoor air contaminants such as combustion products from gas stoves and smoking, and indoor volatile organic compounds from products including disinfectants and air fresheners, as well as chemicals from paint and construction materials.

Medical devices in hospitals use auditory interfaces to keep doctors and nurses updated while keeping their eyes focused on patients. These auditory alarms are crucial for complex procedures, such as placing a breathing tube. Unfortunately, the specific sounds used in current systems are highly problematic. The lack of sophistication in these tones render them annoying and distracting, harming communication amongst medical staff and posing risks for patient care. An FDA survey has revealed hundreds of deaths annually resulting from poorly designed alarms! Although there are many ways to improve their use, one solution has received little attention thus far – improving the quality of the sounds themselves.

Preterm birth refers to the birth of a baby before 37 weeks of completed gestation. An estimated 15 million babies are born prematurely each year and sadly, this prevalence is rising. Approximately 1 million die as a result of premature birth, and those who survive are at risk of lifelong disabilities. Dr Buxton and his team at the University of Nevada, Reno, are studying the role of the smooth muscle of the uterus to elucidate its role in preterm labour and birth.

Bacterial growth depends on the complex interactions of a multitude of chemical components. Microbiologists have long attempted to predict bacterial growth according to culture media components, and have employed a variety of mathematical and computational models to this end. Dr Bei-Wen Ying and her colleagues at the University of Tsukuba, Japan, successfully applied machine learning to understand the contribution of media culture components to bacterial growth. Their work makes a significant contribution to growth prediction and demonstrates that machine learning can be employed in the exploration of the complex dynamics that regulate living systems.
