A UK-wide analysis of bowel screening for patients with IBD has identified opportunities to improve early cancer detection. Regular experience, more time, and use of dye are associated with finding polyps, which may become cancer. The study provides a starting point for measuring and improving care for those with IBD.
Researchers developed a synthetic system to control gibberellin hormone signaling, revealing coordinated root growth across distinct cell layers. Activating GA signaling in specific layers promotes root elongation, with simultaneous activation in both endodermis and epidermis resulting in stronger growth.
Researchers develop linker-editing strategy to create ordered hydrogen-bond networks in COFs, accelerating proton-coupled electron transfer and improving solar-to-chemical efficiency. The urea-COF delivers high photocatalytic H2O2 generation rates and retains 90% activity after six recycling cycles.
Research reveals cancer diagnosis can lead to discrimination in work, finances, healthcare, and social networks, affecting quality of life and health
A Cochrane review found that ergonomic interventions have no significant impact on pain, function, or sick leave for workers with work-related arm, neck, or shoulder complaints. The review of 20 trials involving 2,478 people found little to no difference between ergonomic interventions and no treatment in short-term pain relief.
Researchers have created a portable device for detecting PFAS in water using inexpensive electrodes combined with synthetic antibodies. The device can detect trace levels of PFAS in water, opening a promising route to portable environmental monitoring. The platform is compact, low-cost, and designed for easy manufacturing.
A switching-dependent prescribed performance adaptive control scheme is proposed for switched nonlinear systems, ensuring practical finite-time stability with an explicit settling-time upper bound. The approach constructs mode-specific performance bounds and a dedicated error transformation to resolve switching-induced discontinuities.
GradientScreen, a 'lab-on-a-chip,' measures how a patient's leukemia cells respond to various drug combinations before treatment starts. This technology helps clinicians identify which patients are likely to be unresponsive to standard treatment and personalize treatment approaches.
A promising AI-based approach has been developed to detect early signs of suicide-related behavior in emergency room patients, reducing clinician workload. The model uses routine patient intake data and light-weight computing to estimate risk, and is intended to assist ER staff rather than replace them.
A new study by Bournemouth University reveals that autistic people experience more severe menopausal symptoms, leading to poorer wellbeing and quality of life. The study found stark health inequalities, including higher rates of anxiety, depression, and physical illness among autistic participants.
Research published in Occupational & Environmental Medicine found that night shifts during pregnancy are linked to neurodevelopmental abnormalities in young children. Prenatal sleep length may modify this association, with longer sleep duration associated with an 80% heightened risk of abnormalities.
Three-quarters of responses to the UK's smoke-free generation consultation were AI bot-generated, opposing restrictions on disposable vape sales. Despite this, 77% of valid respondents supported restrictions, highlighting the need for improved governance safeguards to maintain public health policymaking integrity.
