Cell-free synthetic biology biosensors have potential as effective diagnostic technologies for the detection of chemical compounds, such as toxins and human health biomarkers. They have several advantages over conventional laboratory-based diagnostic approaches, including the ability to be assembled, freeze-dried, distributed, and then used at the point of need. This makes them an attractive platform for cheap and rapid chemical detection across the globe.

Purpose: Reported ear and hearing difficulties (rEHD) are known to be associated with reading difficulties as well as mental health problems. In this study, we aim to examine the relationship between reading and mental health in children with rEHD.
Method: In this study, we used structural equation modeling to measure the strength of longitudinal relationships between reading and mental health-related variables in children with rEHD-aged 5-11 years-in four large longitudinal databases from the United Kingdom ( = 5,254), the United States (s = 1,541 and 6,401), and Australia ( = 2,272).

Historical studies performed nearly a century ago using mouse skin models identified two key steps in cancer evolution: initiation, a likely mutational event, and promotion, driven by inflammation and cell proliferation. Initiation was proposed to be permanent, with promotion as the critical rate-limiting step for cancer development. Here, we carried out whole genome sequencing to demonstrate that initiated cells with thousands of mutagen-induced mutations can persist for long periods and are not removed by cell competition or by immune intervention, thus mimicking the persistence of cells with cancer driver mutations in normal human tissues.

Herein, a novel and simple electrospray (ES) printing technique was developed for the fabrication of ultrathin graphene layers with precisely controlled nanometer-scale thickness, where graphene oxide (GO) was electrosprayed on wafers and subsequently chemically reduced into reduced GO (rGO). Utilizing that technique, we prepared ultrathin rGO in-plane graphene field-effect transistor (GFET)-based biosensors coupled with a portable prototype measuring system for point-of-care detection of pathogens. We illustrate the use of such prepared GFETs to detect COVID-19, using the SARS-CoV-2 nucleocapsid protein antigen (N-protein) and genomic viral RNA as detection targets.

Background: Processing data from electronic health records (EHRs) to build research-grade databases is a lengthy and expensive process. Modern arthroplasty practice commonly uses multiple sites of care, including clinics and ambulatory care centers. However, most private data systems prevent obtaining usable insights for clinical practice.
