Faecal sludge, a material derived from human waste, can be difficult to dispose of and causes significant disease and pollution worldwide. However, it also shows potential as a fuel, fertiliser and even a building material, if properly treated. Dr Santiago [san-tee-ah-go] Septien [sep-tee-uhn] Stringel and his team at the WASH R&D [wash R and D] Centre of the University of KwaZulu-Natal [kwah-...

Over the past few millions of years, a succession of ice ages has profoundly influenced the geology of Earth’s northerly latitudes. These past events continue to influence our lives today – particularly in the fertile regions we now rely on for agriculture. By tracing the advances and retreats of ice sheets, Dr Alison Anders at the University of Illinois is gaining important new insights into how...

All women are exposed to oestrogen from puberty through menopause. Oestrogen is a natural hormone that is important for breast development and the maintenance of tissues in women but is also linked to an increased risk of breast cancer. As many as 1 in 8 women in the USA will be diagnosed with breast cancer over their lifetime, and the majority of these breast cancers are sensitive to oestrogen. D...

Important clues buried within ancient rocks that were deposited on the ocean floor around one billion of years ago could help scientists understand the evolutionary history of life on Earth. Dr Romain Guilbaud and an international team of researchers from the UK and China analysed the chemical composition of these rocky sediments from the Huainan Basin in North China. Their findings demonstrate ho...

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. This is a highly promising field of drug development and the focus of Dr Mikail Abbasov from Cornell University, New York, USA. By creating and utilising new technologies and th...

Cancer can be caused by genetic mutations or epigenetic alterations, which are changes to the way DNA is processed, rather than to the DNA itself. These changes can be brought about by obesity, and more specifically, oxidative stress and consequent reactive oxygen species. However, the molecular mechanisms by which this occurs are not well understood. Dr Aliccia Bollig-Fischer from Wayne State Uni...

Stress produces numerous negative effects on the human body. Lying deep within the brain, one particularly sensitive area is the hippocampus, where chronic exposure to stress hormones can lead to the degeneration and death of neurons. Thankfully, the brain holds defence mechanisms that block some of these negative effects. Deciphering these mechanisms with the aim of better treating neurodegenerat...

Explaining complex physical phenomena to students in simple and relatable ways can be challenging. This is particularly true for abstract concepts or phenomena that can only be observed using advanced equipment. Dr AJ Richards, an Assistant Professor of Physics at the College of New Jersey, has been exploring the potential of Kinaesthetic Learning Activities – multi-sensory teaching strategies inv...

Seasonal workers often fill temporary positions that are poorly paid and commonly deemed undesirable by residents. While seasonal work schemes can benefit both employers and the local economy, they often fuel the uneven economic participation and marginalisation of migrants. Professor Ruth McAreavey of Newcastle University recently published a paper outlining issues that should be addressed if sea...

Although obsessive-compulsive disorder (OCD) is a commonly occurring psychiatric disorder, the underlying genetic basis has until recently, remained poorly defined. Drs Christie Burton, Jennifer Crosbie, and Russell Schachar at The Hospital for Sick Children (SickKids) in Toronto, Canada, and Dr. Paul Arnold at the University of Calgary and The Matheson Centre for Mental Health Research & Educ...

The engine of a typical passenger vehicle is made up of hundreds of mechanical parts. These parts require lubrication to prevent them from overheating and to keep them working efficiently. Ken Hope and his team at Chevron Phillips Chemical, headquartered in Texas, have analysed the extent to which different types of lubricant oils reduce friction. They then used this data to estimate how an optimi...

Medical professionals require years of training before they can describe ultrasound images of developing foetuses. Dr Mohammad Alsharid and colleagues from the Institute of Biomedical Engineering and Nuffield Department of Women’s and Reproductive Health at the University of Oxford suggest that this task could one day be carried out by machine learning algorithms. In their latest study, the team s...

Modern microelectronics is currently facing a profound challenge. The demand for even smaller and more closely packed electronics has hit a stumbling block: the power emitted in these devices releases more heat than can be efficiently removed. Now, Professors Valerii Vinokur, Anna Razumnaya, and Igor Lukyanchuk propose a solution based on the seemingly counterintuitive phenomenon of ‘negative capa...

In the next few decades, upcoming technological advances will offer unprecedented opportunities to explore the solar system – both with autonomous robots, and through manned missions. Dr Jekan Thanga and the Space and Terrestrial Robotic Exploration (SpaceTREx) Laboratory at University of Arizona are at the forefront of efforts to design miniature spacecraft that will allow us to reach these dista...

Beneath our feet lies one of the most biodiverse habitats imaginable – the soil. These highly active underground microbial communities are vital to ecosystem health; they cycle nutrients, form soil structure, and decompose organic matter, among many other functions. The type of microbes that colonise soil is determined by the local plant community and climatic variables, both of which are rapidly...

Peer review is a key component in the determination of funding allocation, especially within the science and technology sectors. However, the literature evaluating this process is sparse, often focusing on outcomes rather than the methodology. Dr Tiffani Conner and her colleagues from Oak Ridge Associated Universities in the USA have researched which specific skills are most desirable in a reviewe...

There is an urgent need for prognostic tools that can accurately predict the outcomes of patients undergoing treatment for breast cancer. Dr Fatima Rehman and her colleagues investigated the relationship between breast cancer prognosis and the secretion of a biological marker called Galectin-3 to drive forward the development of optimised treatment regimes. This work was conducted at Shaukat Khanu...

The ‘flipped classroom’ is an innovative educational approach that emphasises active learning, with the aim of increasing student engagement and academic performance. While educators in numerous disciplines have recently started experimenting with this approach, there is still a lack of solid research assessing its effectiveness in the field of teacher education. To fill this gap, Han Han and Fred...

Invasive plants can permanently alter ecosystems to promote conditions that support their own persistence. For example, certain invasive grasses can make areas prone to more frequent and larger wildfires, which negatively impact native species but favour fire-resistant invaders. This self-perpetuating process, termed a grass-fire cycle, can be impossible to reverse. Dr Jeanne Chambers of the Unite...
