As rising temperatures push snakes and humans into closer contact, the world faces an estimated 5.5 million snakebites each year, resulting in 138,000 deaths and 400,000 lasting disabilities. In response, a Wisconsin‑based amateur scientist has taken an extreme route to help solve the crisis.For almost 20 years, Tim Friede, a former window cleaner, allowed some of the planet’s most lethal snakes to bite him, accumulating over 200 intentional bites. His goal: to provoke his own immune system into producing antibodies that could be harvested for a near‑universal antivenom.The endeavor has been perilous. Friede survived a coma after being bitten by two cobras within an hour, endured anaphylactic shocks, lost tissue in a finger, and even had to cut necrotic muscle from his leg. Yet he persisted, eventually becoming immune to the inland taipan—the world’s most venomous snake, whose single bite can kill more than 100 people.In 2019, California biotech firm Centivax hired Friede to extract his antibodies. Early laboratory work showed that his serum can neutralise toxins from 19 elapid species, including cobras, mambas, taipans, coral snakes and kraits—roughly half of all venomous snakes worldwide.The next step is a veterinary trial in Australia, slated for later this year, before any human application. If successful, the antivenom could dramatically reduce the burden of snakebite in low‑income regions across Asia and Africa, where most victims live.Climate scientists warn that warming climates will expand snake habitats and increase human exposure, as illustrated by the recent surge of rattlesnake bites in California’s Ventura County. This amplifies the urgency for scalable, affordable antivenoms, especially as international aid budgets face cuts and manufacturing capacity remains insufficient.Friede’s unconventional path underscores a broader lesson: confronting emerging health threats may require bold, unconventional science, but the potential payoff—a life‑saving treatment for millions—could be transformative.

Sir Paul Marshall, the co-owner of GB News and a self-described 'committed' Christian, has been criticized by a group of 100 church leaders over the TV channel's attacks on climate science and action. The leaders, including former Archbishop of Canterbury Rowan Williams, argue that Marshall's statements on climate change are misleading and that his hedge fund's £1.8bn investments in fossil fuels present a conflict of interest.Marshall has stated that the UK has been infected by 'climate derangement syndrome' and that efforts to cut planet-heating emissions are 'impoverishing people.' In response, the church leaders emphasized that 100% of global heating since 1950 has been caused by human emissions and activities, according to the world's climate scientists. They also noted that decarbonization is a huge growth opportunity that will save trillions of dollars in the long term.The leaders, in an open letter, urged Marshall to be transparent about any personal conflicts of interest and to declare his financial interests in fossil fuels. They cited research that found GB News broadcast 953 attacks on climate science and climate action in the period immediately before and after the 2024 general election.Marshall responded that 'the Gospel entreats us to look after the vulnerable' but argued that pursuing an 'ideological' net zero policy was 'a path of unilateral economic disarmament and self-harm.' He also stated that he was not involved in the editorial decisions of GB News, which has lost £131m since its launch in 2021.The Christian leaders' criticism of Marshall and GB News highlights the ongoing debate over climate change and the role of media outlets in shaping public discourse on the issue. As more than 100 countries have net zero policies and the UK's net zero economy grew by 10% in 2024, the pressure on media outlets to provide accurate and responsible reporting on climate issues continues to grow.
