Micro/nanorobots hold exciting prospects for executing different tasks in complex microenvironments due to their small size, high flexibility, controllability, and environmental adaptability. However, traditional rigid micro/nanorobots are still difficult to perform different biomedical tasks in complex and unstructured narrow microenvironments due to their limited flexibility and insufficient deformability. To address this problem, in a new paper published in PhotoniX, a team of scientists led by Professor Hongbao Xin from Institute of Nanophotonics, Jinan University, China, has developed a new soft microalga robot (saBOT). They innovatively used microalga, ...

Uncovering the relationship between structure (connectivity) and function (neuronal activity) is a fundamental question across many areas of biology. However, investigating this directly in animal brains is challenging because of the immense complexity of their neural connections and the invasive surgeries that are typically needed. Lab-grown neurons with artificially-controlled connections have the possibility of becoming a useful alternative to animal testing, particularly as we learn how to accurately characterize their behaviour. A research team at Tohoku University used microfluidic devices to reveal how directional connections shape the complex dynamics ...

A team of researchers led by UC Santa Cruz recently released a sophisticated new map that reveals, for the first time, the unique “geologic fingerprints” for most of the African continent.  The map will help archaeologists, conservation scientists, and forensics experts match artifacts and plant, animal, and human remains found at locations around the world back to their most likely region of origin within Africa, offering new insights on issues ranging from the history of the transatlantic slave trade to modern wildlife trafficking and human migration patterns.  The research team’s ...

People who care for both their children and older family members – also known as ‘sandwich carers’ – suffer from deterioration in both their mental and physical health over time, finds a new study by UCL researchers. The research, published in Public Health, analysed data from around 2,000 sandwich carers and 2,000 non-sandwich carers from the UK Household Longitudinal Study between 2009 and 2020. Sandwich carers juggle the responsibilities of caring for ageing parents or older relatives while raising dependent children ...

CAMBRIDGE, MA -- When a new species is introduced into an ecosystem, it may succeed in establishing itself, or it may fail to gain a foothold and die out. Physicists at MIT have now devised a formula that can predict which of those outcomes is most likely. The researchers created their formula based on analysis of hundreds of different scenarios that they modeled using populations of soil bacteria grown in their laboratory. They now plan to test their formula in larger-scale ecosystems, including forests. This approach could also be helpful in predicting whether probiotics or fecal microbiota treatments (FMT) would successfully combat infections of the human GI tract. “People ...

A change in the weather in the U.S. Corn Belt Intensive farming and shallow groundwater affect precipitation patterns The sweeping land use changes and irrigation of the U.S. Corn Belt, along with the influence of the area’s shallow groundwater, have significantly altered precipitation patterns in that vital agricultural region, new research shows. The study, published in the Proceedings of the National Academy of Sciences, focuses on “precipitation recycling” — a process in which the moisture released to the atmosphere by plants, soils, lakes, and other features of the landscape returns to the same area in the form of rain. By using advanced ...

Common methods of communicating flood risk may create a false sense of security, leading to increased development in areas threatened by flooding. This phenomenon, called the “safe development paradox,” is described in a new paper from North Carolina State University. Lead author Georgina Sanchez, a research scholar in NC State’s Center for Geospatial Analytics, said this may be an unintended byproduct of how the Federal Emergency Management Agency classifies areas based on their probability of dangerous flooding. Known as flood mapping, this classification system describes areas in terms of their likelihood of being flooded each year. These ...
