Smart contact lenses for cancer diagnostics and screening

Scientists have developed a smart contact lens that can capture and detect exosomes, nanometer-sized vesicles found in bodily secretions, which hold promise for cancer diagnostics. The lens was designed to bind to antibodies capturing exosomes found in tears, offering a potential platform for non-invasive cancer screening.

New method can remove dyes from wastewater

Researchers at North Carolina State University have developed a synthetic polymer that can remove certain dyes from water, and the polymer can be recovered and reused. The study found that the polymer's ability to remove dyes was dependent on solution pH and topological polar surface area of the dyes.

World's first eco-friendly filter removing 'microplastics in water,' a threat to humans from the sea without polluting the environment

Researchers at DGIST and Korea Institute of Industrial Technology developed the world's first eco-friendly microplastic removal technology. The new porous structure-based triboelectric nanogenerator showed a high removal rate of micro-sized microplastics, posing a threat to humans.

Creating an 'adult-like' mature human cardiac tissue

Researchers developed a new cardiac cell-derived platform that closely mimics the human heart, accelerating maturation of human cardiac cells towards a state suitable for preclinical drug testing. The model achieved structural, mechanical, metabolic, and electrophysiological characteristics close to adult heart muscle within 30 days.

Safe havens for cooperation

A research team used game theory to analyze cooperation in networks and found that networks with a high level of cooperation can emerge if individuals take a clear-cut position against free riders. The study also showed that if contributors leave an environment too quickly, it leads to a lower level of cooperation.

Oncotarget | Glypican-3 (GPC3) is associated with MCPyV-negative status and impaired outcome in Merkel cell carcinoma

Researchers found that Merkel cell carcinoma (MCC) Glypican-3 (GPC3) is expressed in nearly 70% of MCC tumors and up to 90% of MCPyV-negative cases. GPC3 expression is associated with worse prognosis, including increased risk of death from MCC. This makes GPC3 a promising target for chimeric antigen receptor T cell therapy.

Study uncovers what happens inside artery plaque to trigger strokes

A study at Tulane University found that recently formed stroke plaques contain messenger RNA that causes inflammation and degrades a protective cap, leading to rupture. This discovery could lead to new tools to stop strokes from happening and develop new drugs or diagnostics to prevent heart attacks and strokes.

Surprisingly simple chemistry enables polyurethane recycling

Researchers at Aarhus University have developed a new and inexpensive way to recycle polyurethane (PU) plastic by breaking it down into its original components. The method uses a simple chemical reaction involving alcohol, caustic potash, and an autoclave, making it cheaper and more scalable than previous methods.

Social rejection could drive people to take COVID-19 safety precautions, new research finds

New research reveals that social rejection can drive individuals to prioritize disease protection. When people experience social pain, they become more likely to take concerted efforts to safeguard against COVID-19. Conversely, when social interactions are less painful, people may be less vigilant in protecting themselves.
