Mosquitoes kill more people than any other animal on Earth, and scientists say the threat is growing. As the climate warms, mosquito seasons are lasting longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Researchers are now exploring new methods to target and control mosquito populations before the expanding range of the insects puts more communities at risk.

An Italian court has convicted three Egyptian security officials over the 2016 torture and killing of Italian student Giulio Regeni in Cairo, while acquitting a fourth defendant. The ruling, delivered in absentia, comes after years of pressure for answers over the researcher's death, which strained relations between Rome and Cairo. All four men were being tried over the abduction and murder of the Cambridge University student near the Egyptian capital.

Leading artificial intelligence researchers are calling for urgent government oversight of self-improving AI systems, according to a Wall Street Journal exclusive. The researchers warn that systems capable of enhancing their own capabilities could pose risks that current safety measures and regulations are not equipped to handle, urging policymakers to act before the technology advances further.

The Trump administration is retreating from a proposed executive order that would have given the White House greater control over National Institutes of Health grant decisions. Reporting by Semafor says the plan, which would have tightened political oversight of NIH research funding, is now considered 'dead' after significant pushback from scientists, universities and lawmakers. The retreat comes amid ongoing concerns over federal science funding policy.

Leading AI researchers often described as the 'godfathers' of the field have publicly warned about the risk of a runaway 'intelligence explosion', in which AI systems rapidly improve themselves beyond human control. The warning, reported by The Guardian, adds to ongoing debate among scientists and policymakers about how quickly advanced AI should be developed and regulated.

The New York Times is examining whether Anthropic's AI system genuinely produced a scientific discovery independently or whether human researchers guided the result. The question has sparked debate about how much credit AI systems can claim for original scientific work, and where the line sits between genuine machine autonomy and sophisticated assistance. Anthropic is among the leading AI developers, and the claim touches on its positioning in the competitive AI field.

New analysis indicates the global heatwave season has expanded by roughly 39 days, with extreme heat now arriving earlier in the year and lasting longer than before. Researchers attribute the lengthening season to warming temperatures, warning that prolonged exposure raises health risks and strains infrastructure. Coverage highlights how gradual change can go unnoticed even as extreme heat events become more frequent and severe.

Bill Gates says that simply having an emergency 'kill switch' to shut down advanced artificial intelligence would not be enough to manage the technology's risks. His comments feed into a wider debate among tech leaders, researchers and regulators over how to keep increasingly powerful AI systems safe and under meaningful human control.

New polling indicates climate change has returned to people's top priorities, according to research by Climate Outreach. The organisation shared the finding publicly, suggesting renewed public concern about the issue after a period in which it had slipped down voters' lists of most important concerns. Further details from the poll, including specific rankings and regional breakdowns, were not provided.

A judge has ordered the Canadian government to release sealed records about Nazi war criminals who settled in Canada after the Second World War. The documents are believed to detail how suspected war criminals entered and remained in the country, a question that has long been the subject of historical research and public debate about government secrecy and Canada's wartime immigration record.

United Nations University researchers argue that efforts to regulate artificial intelligence should be grounded in human rights law rather than starting from scratch. The piece contends that existing international human rights frameworks already offer states tools to address harms from AI, including discrimination, surveillance and due process concerns. It calls on governments to anchor emerging AI governance rules in rights-based obligations.

The digital euro has made its first appearance in wholesale financial markets, marking a step in the European Central Bank's push toward a central bank digital currency. The debut signals that the eurozone is moving beyond research stages and testing how a digital version of the currency could function for institutional financial transactions. Details on scale and participants remain limited, but the development is being closely watched as Europe weighs a broader rollout.

DW News examines whether India's growing crop of space startups can transform the country into a leading space power. The report highlights how private companies are building on the achievements of the Indian Space Research Organisation, which has drawn global attention for low-cost missions such as Chandrayaan-3 and Aditya-L1. It looks at whether entrepreneurial firms can scale satellite launches, services and innovation fast enough to rival established players like the US, China and Europe.

A new study warns that North Korea's nuclear weapons tests have caused more than 1,000 earthquakes around the country's test site. Researchers link the seismic activity to underground detonations, raising concerns about structural damage, possible leaks of radioactive material, and the stability of the Punggye-ri test area as tremors continue even after testing paused.

A New York Times piece examines how scientists can influence public opinion on the risks of artificial intelligence, reportedly through protests and public engagement. It suggests researchers are becoming active voices in the debate over AI safety, rather than leaving the conversation to companies and regulators.

Schools across the United States are adopting artificial intelligence tools in classrooms, but educators are doing so with little research evidence on effectiveness and few official policies to guide use. NPR reports that districts are experimenting with AI for teaching and administrative tasks while questions remain about impacts on learning, academic integrity, and data privacy.

Researchers have published a ranking of the risks posed by increasingly capable smart systems, placing potential catastrophes such as nuclear war, bioweapons development, and loss of control over advanced AI among the most severe threats. The work compares how experts weigh these scenarios and is drawing attention to how the field prioritises safety research as systems grow more powerful.

According to a Wall Street Journal report, 18.8% of working-age people now use artificial intelligence tools.
