New research published in Nature reports evidence of viral reactivation in patients with both acute and long COVID-19. The findings suggest that remnants of the virus, or its genetic material, can become active again in some individuals, potentially contributing to persistent symptoms. This highlights a possible mechanism underlying long COVID and may inform future treatment strategies.

Researchers developed an encapsulation epitaxy technique to produce atomically thin superconductors that remain stable in air. This overcomes a major barrier to integrating 2D superconductors into practical quantum circuits. The advance could enable more scalable and robust quantum computing hardware.

Scientists have developed a chemical method to transform low-value mixed plastic waste into high-demand industrial commodities. The technique, reported in Nature, can efficiently break down and re-form plastics into materials like surfactants and lubricants. This offers a promising route to reduce plastic pollution and create economic incentives for recycling.

Several parts of the UK recorded no rainfall for an entire month for the first time on record, according to New Scientist. The unprecedented dry spell highlights the growing impact of climate change on Britain's normally wet weather. It raises serious concerns about water shortages, agriculture, and wildfire risk across the region.

A prominent commentary argues that the World Health Organization is now more critical than ever due to escalating global health risks like pandemics and climate change. Despite past criticisms and funding challenges, the WHO’s role in coordinating international response is indispensable. Strengthening the agency is vital for global preparedness and equity.

OpenAI announced it has solved 10 longstanding mathematics problems, a potential breakthrough for AI reasoning. The solutions, if verified, could significantly advance both mathematical research and the development of AI systems that can tackle complex scientific challenges.

An NHS mental health trust in the UK has announced proposals to reduce spending by £25 million, primarily through job losses and service reductions. The cuts stem from ongoing financial pressures and will likely affect access to mental health care. This matters because services are already under strain, and further cuts could deepen the impact on patients.

Researchers have engineered antibodies that combine two cancer-fighting mechanisms, enhancing their ability to target and destroy tumors. The dual-action approach shows promise for more effective cancer immunotherapy treatments in preclinical studies.

The White House sharply criticized the Spanish government after thousands of migrants surged from Morocco into Spanish enclaves. Spain's emergency request for additional EU assistance was denied, intensifying diplomatic tensions over border management and migration policy. The incident highlights ongoing strains in transatlantic and European responses to migration surges.
