Colorectal cancer (CRC) represents one of the most urgent yet addressable oncology challenges confronting Latin America. In Mexico, digestive tract cancers remain a leading contributor to cancer mortality, while CRC continues to rank as the second-most common malignant neoplasm among Latino populations in the Americas.

This crisis stems less from a lack of therapeutic advances than from severe diagnostic bottlenecks. In several large regional hospital networks, the median interval from initial symptom onset to definitive treatment stretches to seven months. The longest portion of that delay occurs between initial clinical evaluation and diagnostic confirmation. When health systems rely on late stage symptomatic presentation, oncology care becomes reactive, expensive, and frequently palliative.

Subcutaneous immunization with live influenza virus in mice provided durable protection against lethal flu, outperforming intramuscular or inactivated vaccines. The virus remained restricted to the injection site and lymph nodes without causing lung damage. A single dose gave 100% protection for 277 days through strong germinal center responses.

Researchers developed SwiVirScan, a screening platform containing 36,416 peptides from 140 swine-associated viruses. In 127 adult breeding pigs, every serum sample showed antibody reactivity to peptides assigned to multiple viruses. The study also identified a persistent association between antibody signals for porcine bufavirus and porcine circovirus 3. The findings can guide follow-up surveillance, but antibody signals alone do not establish active infection.

Agrophotovoltaics (APV), as an innovative model integrating agricultural production with solar photovoltaic power generation, is an important pathway to address the dual pressures of food security and low-carbon energy. As the global energy transition accelerates and agricultural modernization advances, its advantages of “dual land use and food–energy co-production” have become increasingly prominent. It can achieve efficient land use while accommodating clean electricity output and crop growth, aligning with the needs of sustainable development. However, for a long time, traditional models have been constrained by bottlenecks such as imbalanced light distribution, lagging temperature and humidity regulation, inefficient manual operation and maintenance, and data fragmentation, making it difficult to balance energy and agricultural benefits and seriously hindering large-scale promotion.
