The wearable, stretchable, hydrogel-based sensor offers a non-invasive method to monitor health by detecting biomarkers such as cholesterol and lactate directly on the skin. [ + ]

Mitochondria in our brain cells frequently fling their DNA into the nucleus, where the DNA becomes integrated into the cells' chromosomes. These insertions may be causing harm. [ + ]

If you come across any brightly coloured, cloth-bound books from the Victorian era, you might want to handle them gently or even steer clear altogether. [ + ]

Scientists say they have discovered why the flu vaccine can perform poorly, having found that a specific type of immune cell indirectly controls the anti-influenza response. [ + ]

The point-of-care electrochemical biosensor prototype can measure levels of two biomarkers for heart failure in as little as 15 min from just a drop of saliva. [ + ]

Researchers have designed a shunt that expands when activated by light, which could reduce the number of open-chest surgeries required by children with congenital heart defects. [ + ]

The world's most sensitive dark matter detector has narrowed down the possibilities for one of the leading theoretical dark matter candidates: weakly interacting massive particles, or WIMPs. [ + ]

Researchers have used aerosols to detect altered atmospheric transport patterns associated with climate change, observing that the distance of transboundary air pollution moving east from China has shortened. [ + ]

A first-in-kind clinical trial has tested the safety and efficacy of a JAK inhibitor in decreasing the burden of autoimmune skin conditions in people with Down syndrome. [ + ]

In industrial processes and laboratories, vapours have a useful role. So what are vapours, where are they used, and how can they be delivered in a controlled way to these processes? [ + ]

The process of translating pain into a 'threat memory' occurs so quickly that scientists originally thought it must be mediated by fast-acting neurotransmitters, but it turns out this is not the case. [ + ]

An upright neuroimaging device allows patients to move around while undergoing a brain scan, addressing issues with traditional positron emission tomography scanners. [ + ]

Highly potent immune cells gather in regional bone marrow niches close to the glioblastoma tumour and organise the defence from there. [ + ]

This two-part series illuminates design and implementation principles for ensuring an efficient, reliable and cost-effective compressed air supply — which is often possible without major effort. [ + ]

Expectant mothers who eat a high-fibre diet can reduce the risk of heart disease in their offspring, while fathers' diets can program certain characteristics of the next generation even before conception. [ + ]
