Abstract There is increasing evidence linking the gut microbiota to various aspects of human health. Nuts are a food rich in prebiotic fibre and polyphenols, food components which have been shown to have beneficial effects on the gut microbiota. This systematic review aimed to synthesise the evidence regarding the effect of nut consumption on the human gut microbiota. A systematic search of the databases MEDLINE, PubMed, Cochrane CENTRAL and CINAHL was performed until 28 November 2019. Eligible studies were those that investigated the effects of nut consumption in humans (aged over 3 years ol...

Researchers have independently validated industry-leading blood tests that can detect the DNA released by tumours. An international team today reports the findings of an independent assessment of five commercially-available assays for tumour DNA sequencing – a fast, cheap and less invasive method to diagnose and monitor cancer. The researchers revealed that all assays could reliably detect so-called circulating tumour DNA (ctDNA) when it made up 0.5% of the total DNA in blood, a level of sensitivity that allows detection, genetic analysis and monitoring of late-stage and metastatic tumours....

Leopards are among the most widespread carnivores today, living in a wide range of habitats, from deserts to rainforests, and from the lowland plains to the mountainous highlands. Over the past century, they’ve experienced extreme habitat losses due to human activity, both directly from hunting and indirectly from habitat reduction and prey competition. This has led to the land they occupy being reduced by over 50% in Africa, and over 80% in Asia, involving the local extinction of many populations. Genetic analysis of leopards is important to understand their population history, structure ...

Date Time Shutting nano-gate Researchers at Osaka University create voltage-controlled nanopores that can trap particles as they try to pass through, which may lead to single-molecule sensors, along with cheaper and faster genomic sequencing Scientists from the Institute of Scientific and Industrial Research at Osaka University fabricated nanopores in silicon dioxide, that were only 300 nm, in diameter surrounded by electrodes. These nanopores could prevent particles from entering just by applying a voltage, which may permit the development of sensors that can detect very small concentrations...

New publication by iDiv member at IPK Leibniz Institute Based on a press release by IPK Leibniz Institute Gatersleben. Genomes differ between the individuals of one species and we can learn a lot about diversity in our crops by comparing genomes of different varieties. However, researchers that want to study many genomes need a fast and reliable method for sequence assembly. An international research team led by the IPK Leibniz Institute has now investigated a new DNA sequencing method. The results, which have now been published in the journal The Plant Cell, are very promising. The scientist...
