A large international team has developed a new compound that showed strong antiviral activity against HIV, including some drug-resistant variants.

Paired DNA strands recognize shape, not just sequence, in new small-molecule sensing method
You have probably performed a sandwich assay before, even if you didn't know it. Sandwich assays are the molecular sensing technology behind lateral flow tests like the at-home COVID test. After a sample is dripped onto the test strip, it combines with detector antibodies attached to tiny gold particles, which bind to any viral proteins present. When the sample reaches the test line, a second antibody anchored to the strip binds to a different site on the viral protein, creating a molecular "sandwich." As the gold particles accumulate, the test line turns dark red, becoming visible to the naked eye.
A plant-based hair dye that smells like cinnamon
Hair dyes help people express style and cover gray hair but often contain skin-irritating chemicals.
Coating made from renewable plant-based materials could simplify recycling while reducing exposure to microplastics
The lining in traditional disposable coffee cups can release plastic particles and be difficult to recycle, but a new plant-based coating can eliminate these issues with your morning brew.
Traditional Korean paper becomes breathable patch for future wearable health care
Wearable health-monitoring devices are becoming increasingly important for personalized health care, but conventional patches often rely on substrates that restrict airflow, trap sweat and cause skin discomfort during prolonged use. These limitations can also interfere with the reliable collection and analysis of sweat, highlighting the need for breathable materials that support both comfortable wear and accurate sensing.
Bio-based smart coating combines fire protection, early warning and upcyclability
Researchers have developed a multifunctional fire-protective coating that not only shields materials from extreme heat but also provides an early warning of fire and can be recycled into new flame-retardant materials at the end of its life. The work, published in Polymer Degradation and Stability, demonstrates a strategy for combining fire safety, sustainability and circularity within a single material system.
