The new AEC-MS protocol provides comprehensive analysis of highly polar and ionic metabolites, improving molecular specificity and selectivity. This innovation has led to new applications in metabolomics, including studies on gut microbiome metabolism and energy substrate utilization.
A new study suggests that offering self-collection kits during routine GP appointments can increase participation rates among women overdue for cervical screening. The approach shows promise in reducing the number of cases and saving lives.
Researchers at UCSF have discovered that human lung tissue contains hematopoietic stem cells (HSCs) capable of producing red blood cells, platelets, and immune cells. The finding suggests the lungs could be a potent source for life-saving stem cell transplants, particularly for patients with leukemia.
Researchers have created a water-soluble fluorescent spray that can visualize latent fingerprints in just ten seconds. The new dye-based technology is non-toxic, biologically compatible, and reduces the risk of damaging DNA evidence.
A new multiplex assay has been developed to assess activated p300/CBP in circulating prostate tumor cells, revealing correlations with clinical outcomes and potential therapeutic targets for castration-resistant prostate cancer. The study found that patients with upregulated p300/CBP activity had shorter response times to ARSI therapy.

The technology has shown promising results in detecting TB in underserved areas, with high concordance rates compared to culture diagnosis.
A team of researchers from China and the UK has developed new ways to optimise the production of solar fuels by creating novel photocatalysts. These photocatalysts, such as titanium dioxide with boron nitride, can absorb more wavelengths of light and produce more hydrogen compared to traditional methods.
A team of Brown researchers has developed a new, highly accurate method for detecting antidepressants in patients using liquid chromatography tandem mass spectrometry. The technique requires minimal biological samples and can be fully automated using liquid-handling robots.
A Brazilian research team has developed a novel method to sort specialty and standard coffee beans using multispectral imaging and machine learning. The technique, which does not require roasting or human intervention, uses images of the beans at different wavelengths to distinguish between quality levels.
A new sample preparation method called 'water droplet-in-oil' (WinO) has been developed to improve efficiency in single-cell proteomics. The technique reduces sample loss and increases throughput by up to 10-fold compared to conventional methods.
Researchers emphasize the need for monitoring drinking water for HIV medications, as they can contaminate rivers and streams through wastewater. The lack of regulation on pharmaceuticals in wastewater treatment plants poses a significant challenge in ensuring safe drinking water.
Researchers have developed a new method for preparing cryo-electron microscopy samples using liquid nitrogen, which cools at rates roughly 50 times slower than ethane. This results in sharper images with reduced beam-induced motion and simplified workflows.
Researchers at the National Eye Institute developed a new sample preparation method to detect SARS-Cov-2, simplifying purification and potentially reducing test time and cost. The method uses a chelating agent to preserve RNA in samples, allowing for direct detection and increasing sensitivity.
