Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few resources. But now, a team has developed a sensitive method that analyzes viral nucleic acids in as little as 20 minutes and can be completed in one step with 'glow-in-the-dark' proteins.

Since the development of functional magnetic resonance imaging in the 1990s, the reliance on neuroimaging has skyrocketed as researchers investigate how fMRI data from the brain at rest, and anatomical brain structure itself, can be used to predict individual traits, such as depression, cognitive decline, and brain disorders. But how reliable brain imaging is for detecting traits has been a subject of wide debate. Researchers now report that stronger links between brain measures and traits can be obtained when state-of-the-art pattern recognition (or 'machine learning') algorithms are utilized, which can garner high-powered results from moderate sample sizes.

In a world experiencing growing inequality and intolerance, tools borrowed from science and mathematics could be the key to understanding and preventing prejudice. Experts apply evolutionary game theory, which combines techniques from economics and biology, and complex system analysis to investigate the relationship between inequality and intolerance. They found that inequality boosts intolerance and that redistribution of wealth can prevent its infectious spread.

Researchers create a biomimetic model to study wound healing in burn and laceration wounds. The team designed an in vitro model system made of fibroblasts embedded in a collagen hydrogel. Wounds were created in this microtissue using a microdissection knife to mimic laceration or a high-energy laser to simulate a burn. They discovered that fibroblasts clear away damaged tissue before depositing new material. This part of the healing process is slower in burn wounds.

The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.

Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.
