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 Trump administration has announced it will pay French energy major TotalEnergies $1 billion to kill plans to construct wind farms off the US east coast. This decision comes as a fuel crisis triggered by the war in Iran drives up global fossil fuel prices.The deal is the latest blow to the US offshore wind industry, which has faced repeated disruptions to multi-billion-dollar projects under Donald Trump. Trump has expressed his dislike for wind turbines, citing their ugliness, cost, and inefficiency, and his administration has moved to increase domestic fossil fuel production.In the deal, TotalEnergies will give up two offshore leases it had purchased off New York and North Carolina. The US Department of the Interior will reimburse the company $928 million it paid for the leases under Joe Biden. TotalEnergies has pledged not to develop any new offshore wind projects in the country and will invest nearly $1 billion this year in the development of four trains at the Rio Grande LNG plant in Texas, and the development of upstream conventional oil in the US Gulf and shale gas production.Critics of the deal, including climate advocates and environmental groups, argue that it will deepen the country's dependence on volatile fossil fuel markets and undermine efforts to transition to cleaner energy sources. They also point out that offshore wind projects can provide reliable and affordable power to the grid. The decision has been met with criticism from groups such as Oceantic Network, Evergreen Action, and Sierra Club, who argue that it will leave American consumers struggling to pay their electricity bills and undermine efforts to address climate change.

In rural Northern Ireland, the unmistakable sight of heating oil tankers making deliveries has become a double-edged sword. While these deliveries provide essential warmth, they also inadvertently mark homes as targets for criminals who monitor these visible supply routes.The decades-long issue of heating oil theft has intensified dramatically following the conflict in the Middle East, which has driven up the price of what locals now call 'liquid gold' to unprecedented levels. 62% of households across Northern Ireland depend on oil for heating, with rural reliance reaching 80%, making the region particularly vulnerable to both price shocks and related criminal activity.Since the US and Israel began attacking Iran on February 28, the cost of heating oil has almost doubled to approximately £1,000 for 900 litres. This price surge has transformed what was once a nuisance crime into a serious financial threat for many families.'Rural homes and farms are increasingly being targeted by opportunistic thieves,' said Gary McCartney, regional director of Countryside Alliance Ireland. 'A tank can be drained in minutes.'The consequences extend beyond financial loss. Gareth Kelly and Aimee Leigh Brolly, a couple in Limavady, County Derry, recently woke to choking fumes from an oil line severed by thieves, forcing them to vacate their home with their newborn son due to safety concerns.Police have issued security recommendations, including high-quality padlocks, motion-sensor lighting, and oil-level detection alarms. 'Long term, use fencing or prickly hedging to keep your tank out of sight from the road,' authorities suggest.Experts describe the phenomenon as opportunistic rather than organized crime. 'To call it organised crime is a stretch. This is low level,' said Jonny Byrne, a criminology lecturer at Ulster University. A former police officer agreed, noting that while organized crime groups might eventually become involved, 'it is more opportunistic than organised' at present.The Rural Community Network believes theft is significantly underreported, especially in isolated areas. 'Theft is more noticeable when prices are high,' said CEO Kate Clifford. 'Oil is like liquid gold. It's highly valuable and easy to steal.'This pattern mirrors similar spikes during Russia's invasion of Ukraine in 2022, when the Rural Community Network itself lost £1,700 worth of fuel to thieves who went undetected for an extended period.

Researchers at Cortical Labs in Melbourne have created a 'biological computer' using living human tissue, which can play the 1993 shooter game Doom. The team used 10ml of blood from CEO Hon Weng Chong to harvest 100 white blood cells, which were then reprogrammed into induced pluripotent stem cells (iPSCs). These cells were used to create a dish of 200,000 neurons that can interface with a computer system.The brain cells were taught to play Doom by encoding game state information, passing it through a neural network, and converting it into signals the neurons can understand. The neurons then fire an output, which the system decodes and converts back into actions in the game. This process is similar to how humans operate, with information going into the retina, being converted into electrical signals, processed in the brain, and resulting in an output.While the achievement has sparked concerns about sentience and consciousness, Chong believes the brain cells are not conscious, stating, 'At first it didn’t know how to move, aim or shoot. Then it would shoot two enemies and stop. So it’s definitely learning.' The next step could be integrating this technology with Neuralink, a brain-machine interface developed by Elon Musk.The application of biological computing lies not in gaming, but in medicine, such as disease modeling for conditions like epilepsy. This technology could allow for personalized drug testing and tailored treatments. Meanwhile, Eon Systems in San Francisco has created a virtual insect brain that can behave like a real fly, challenging the assumption that intelligence must be acquired.Biological systems like these could eventually power robots, drones, and other machines that need to navigate complex environments. As Chong notes, 'Abstract reasoning, mathematics and language are relatively recent in evolutionary terms... but motor control and probabilistic decision-making are things we’ve inherited through millions of years of evolution.' While we're far from uploading human consciousness into the internet, this technology marks a significant step in the development of biological computing.
