The UK government has instructed HS2 Ltd to assess the feasibility of operating its high-speed trains at reduced speeds, aiming to curb escalating costs and facilitate an earlier launch in the 2030s. The proposal involves limiting train speeds to 186mph (300km/h), a significant decrease from the initially planned 224mph. Potentially billions of pounds in savings could be achieved through this adjustment, which would bring the project more in line with typical European high-speed rail standards. Currently, most UK trains operate at a maximum speed of 125mph, while HS1 trains serving Kent and the Channel tunnel reach up to 186mph. Transport Secretary Heidi Alexander has commissioned HS2 Ltd to report back on the potential savings from slower trains before the summer recess. This development follows a review by HS2's new CEO, Mark Wild, who has been working to regain control of the project's costs and delays. Alexander acknowledged the challenges facing the project, stating that previous plans significantly underestimated the work required. Despite these challenges, she praised Wild's leadership and noted that HS2 is now making progress, having completed the excavation of all 23 miles of deep tunnels needed for the initial stage of the railway. The project's overall budget is expected to be reassessed and restated in 2026 prices, with predictions that it will exceed £100bn due to soaring inflation and rising labour and steel costs. As of now, the total expenditure stands at £46.2bn at current prices. Government sources suggest that the original design for the world's fastest railway was “gold-plated” and “needlessly overspecced”, contributing to the cost overruns. Wild emphasized that speed was never the primary objective, and the railway's focus should be on delivering better journeys, increased network capacity, and economic growth.

The Albanese government is likely to introduce an extra levy on gas producers' high profits in response to the Iran crisis driving up energy costs for Australians. The prime minister's department has requested Treasury modelling of additional levies on gas companies, stating that energy producers 'should not benefit from high international prices at the expense of domestic customers'.Australia's gas industry is reaping extraordinary profits while households and businesses struggle with high fuel prices. This has sparked calls for a fair share levy to ensure gas companies pay their fair share of tax. The levy, based on Norway's taxation model, would see Australia share around 50% of profits, much more in line with world standards.Currently, Australia shares only 27% of fossil fuel profits, with some estimates as low as 18% when profit is defined in cashflow terms. In contrast, other major fossil fuel exporting countries typically share between 75% and 90% of profits.The fair share levy would provide significant and immediate cost-of-living relief if some of the revenue raised was returned to households. Research shows 87% of voters support a fair share levy, with only 3% disagreeing.Despite potential outrage from the gas industry, the levy is designed to not increase gas prices or deter investment, as seen in Norway's successful implementation. A stable, long-term commitment to the fair share levy would provide investment certainty.

The US and Iran have been engaged in secretive backchannel talks, mediated by countries such as Egypt, Pakistan, and Oman, in an effort to prevent further escalation of the conflict in the region. The talks, which were denied by Iran initially, may lead to a resolution, but the path forward remains uncertain.According to reports, US special envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi have been in communication, with the Egyptian Foreign Ministry tweeting that conversations were underway on Sunday, 24 hours before Donald Trump's deadline to start attacking Iran's energy infrastructure.The talks have been chaotic, with multiple mediators jostling for the title of peacemaker in chief. Pakistan's army chief, Asim Munir, spoke with Trump on Sunday, while Pakistani Prime Minister Muhammad Shehbaz Sharif held talks with Iranian President Masoud Pezeshkian on Monday.Iran's Foreign Ministry initially denied any talks had taken place, saying: “There is no negotiation whatsoever between Tehran and Washington.” However, the ministry later opened up, with spokesperson Esmail Baghaei saying that messages had been exchanged through friendly countries, indicating America's request for negotiations to end the war.The talks may yield a complete and total resolution in the war, according to Trump, who announced that he was holding off from attacking Iran's energy infrastructure due to the “very good and productive conversations” that had been held with Iran.A 15-point deal has been proposed, including joint control of the strait of Hormuz, no nuclear bombs, and no enrichment of uranium. However, Iran's willingness to agree to abandon its right to enrich uranium remains a major sticking point.If talks fail, Trump warned: “We'll just keep bombing our little hearts out.”

UK Prime Minister Keir Starmer has indicated that the government is considering providing support for household bills next winter, as the energy price shock triggered by the Iran conflict shows no signs of abating. Speaking to the Commons liaison committee, Starmer emphasized the need to examine 'every lever that's available' to help households cope with the cost of living impact. The government is reportedly discussing contingency plans at an emergency Cobra meeting, which will be attended by the governor of the Bank of England. Starmer suggested that any support would likely be targeted at the poorest households, rather than a universal bailout, which he acknowledged would be expensive. Ministers are also exploring means-testing support when the next energy price cap comes to an end in June, as well as in the autumn when energy consumption and bills are higher. 'We're looking at in the first instance what happens when the current price cap ends, which is the end of June,' Starmer said. The prime minister warned that despite US President Donald Trump's decision to postpone airstrikes on Iran's power plants, the energy crisis could continue for months to come. 'All of our focus and energy has to be in the swift de-escalation, but we've got to plan on the basis that it could go on for some time,' he said. In addition to support for household bills, the government is considering giving the Competition and Markets Authority (CMA) 'further teeth' to prevent companies from exploiting the crisis through price gouging or profiteering.

The recent meningitis outbreak in Kent has tragically claimed the lives of two young people, with 18 confirmed cases and 11 others being investigated. The outbreak, which has affected four schools and two universities in the Canterbury area, has disrupted thousands of lives and understandably instilled fear among many.The public health response, including contact-tracing, treatment with preventive antibiotics, and localized vaccinations, appears to have been effective in limiting the spread of the disease. The NHS has administered about 2,500 vaccines and issued almost 10,000 precautionary doses of antibiotics.The meningitis B (MenB) strain of bacteria behind this outbreak has caused septicaemia and infection of the membranes surrounding the brain and spinal cord. Despite scientists not fully understanding what causes meningococcal bacteria to become invasive, the public health system has been able to manage the situation.The incident serves as a reminder of the importance of maintaining effective public health systems and the need for evidence-driven decision-making in responding to outbreaks. The UK's success in tackling infectious diseases, including a dramatic reduction in meningococcal disease deaths, is a testament to the effectiveness of prevention, vaccination, and improved treatment.As the risk of future pandemics remains, it is crucial that politicians and the public are reminded of the vital role of public health systems in preventing and managing outbreaks. The abolition of NHS England and its impact on the existing structure overseeing infection prevention and control will require careful consideration.

Palantir, one of the world's biggest tech companies, has been accused of launching an intimidation campaign against a small Swiss magazine, Republik, after it published an investigative report on the company's activities in Switzerland.The report, which was a collaboration between Republik and the independent Swiss research collective WAV, alleged that Palantir had persistently courted Switzerland but had been rejected. The investigation found that Palantir had pitched itself to Switzerland's chancellor during the Covid-19 pandemic to help with data tracking, approached the Swiss army, and met Switzerland's then finance minister, Ueli Maurer.Palantir was not happy with the report and filed a lawsuit in a Swiss commercial court demanding that Republik print a detailed rebuttal. The company claims that the report paints a false and misleading narrative about Palantir and sets back important discourse on European software modernisation.The journalists behind the report say they had interviewed company executives and sent a full list of questions before publication, but that Palantir demanded they print a detailed rebuttal that went beyond the scope of their investigation. The lawsuit has sparked concerns about Palantir's tactics and the impact on journalism, with the European Federation of Journalists claiming that the legal action is an attempt at intimidation aimed at discouraging critical analysis of Palantir's activities."It does feel like an intimidation campaign," says Marguerite Meyer, a journalist who works with WAV. "However, we adhered to all journalistic standards, and had a thorough factcheck done. They are suing for an absurd list of changes."The investigation, which was published in December, gave an account of Palantir's years-long efforts to try to sell itself to the Swiss government. The journalists found that despite Palantir's efforts, no government contracts had been reported."We tried to find out, is there any kind of government agency that uses this software? I mean, they are in Switzerland, eventually some government official maybe thought they could use this Palantir," says Balz Oertli, who is also with WAV.The lawsuit has raised questions about Palantir's influence and the limits of journalistic scrutiny. Swiss law allows the subjects of a story to request a right of reply, but this has caveats: the right of reply has to be concise and stick to the facts of the story."This lawsuit for a right of reply is not about whether Republik was technically inaccurate or not. It is only about whether Palantir is allowed to place its view of the facts alongside that of Republik and whether Republik must publish it," says Dominique Strebel, an expert in media law and the editor-in-chief of Beobachter, another Swiss magazine.

Scientists have made a groundbreaking discovery that could lead to the development of new obesity drugs. By studying the unique metabolic abilities of pythons, researchers have identified a molecule that appears to play a crucial role in regulating appetite and weight loss. The molecule, called pTOS, was found to increase significantly in the blood of pythons after they eat, and when administered to obese mice, it led to a significant reduction in food intake and a 9% loss of body weight over 28 days. The discovery could lead to the development of new obesity drugs that work in a different way to existing medications, such as GLP-1 medications like Wegovy. Unlike these medications, which can have side effects such as nausea and stomach pain, pTOS appears to act on the brain's appetite centers, reducing food intake without these adverse effects. The researchers, led by Dr. Jonathan Long from Stanford University and Prof. Leslie Leinwand from the University of Colorado Boulder, published their findings in the journal Nature Metabolism. They believe that pTOS, which is naturally produced by the snake's gut bacteria and also found in human urine, could be a safe and effective treatment for obesity. While further research is needed before the findings can be applied clinically, the discovery is seen as a promising step towards the development of new obesity treatments. The study's results suggest that pTOS could be a potential therapeutic target for the treatment of obesity and related metabolic disorders.

The typical car has grown significantly in size over the years, with SUVs now accounting for 46% of global new car sales. While they offer more space and a higher vantage point for occupants, they pose significant risks to pedestrians, particularly children, who are 77% more likely to die if struck by an SUV compared to other cars.London Mayor Sadiq Khan is taking steps to address these concerns, including a review of SUVs' environmental impact and potential policy proposals such as higher charges for SUV owners. This move is in line with public sentiment in other cities, where residents have shown support for measures like tripling parking fees for SUVs in Paris and higher parking charges in Cardiff.The UK government can learn from cities like Helsinki and Oslo, which have achieved significant reductions in road deaths and serious injuries. London's ultra-low emission zone (Ulez) has also led to significant air quality improvements since its rollout in 2023. However, the government needs to address the issue of SUVs' large carbon footprints, including their manufacture, which consume about 20% more oil than medium-sized cars.The conversation about the UK's growing number of giant cars needs to accelerate, and Ministers should re-examine the tax system for new SUVs, which are currently taxed far less heavily than in many European countries. By taking bold action, the government can make the city cleaner and safer for its residents.
