The global food system is facing an unprecedented threat of collapse, much like the financial system did in 2008. The concentration of power in the hands of a few large corporations has led to a loss of diversity, redundancy, and modularity, making the system highly vulnerable to shocks.Recent data suggests that every part of this system is now highly concentrated in the hands of a few corporations, which have been consolidating both vertically and horizontally. One recent study found that the US food system has “consolidated nearly twice as much as the overall economic system”. Some of these corporations, diversifying into financial products, now look more like banks than commodity traders, but without the same level of regulation.These vulnerabilities are exacerbated by the use of just-in-time supply chains and the funnelling of much of the world’s trade through a number of chokepoints. Some people have long warned that the strait of Hormuz, alongside the Suez canal, Turkish straits, Panama canal and straits of Malacca, are critical chokepoints, whose obstruction would threaten the flow of food, fertiliser, fuel and other crucial agricultural commodities.When a system has lost its resilience, it’s hard to predict just how and when it could go down. The collapse of one corporation? The simultaneous closure of two or more chokepoints? A major IT outage? A severe climate event coinciding with a geopolitical crisis? The next step could be contagious bankruptcy and cascading failure across sectors.We know what needs to happen: break up the big corporations; bring the system under proper regulatory control; diversify our diets and their means of production; reduce our dependence on a handful of major exporting countries; build strategic food reserves, accessible to people everywhere. But there’s a problem, and it’s not just Trump. Almost all governments are beholden to corporate and financial power.The best we can hope for is that braver politicians in our own countries seek to insulate us from the worst impacts. A crucial step is to encourage a shift to a plant-based diet. People struggle to see the relevance, but it’s simple. A plant-based diet requires far fewer resources, including just a quarter of the land a standard western diet requires and much less fertiliser and other inputs.

Denis Lavant delivers a captivating performance in 'Redoubt', a Swedish film directed by John Skoog. Lavant plays Karl-Göran Persson, a farmhand from rural Sweden who becomes fixated on transforming his humble shack into a public shelter, dubbed a 'redoubt', in preparation for a potential nuclear catastrophe.The film, shot in stunning monochrome, chronicles Persson's journey as he scours the countryside for materials to fortify his shelter. His obsession is sparked by an official pamphlet warning citizens of the impending threat of nuclear war. As Persson works tirelessly on his project, he faces a mix of curiosity and hostility from the local community.Lavant's portrayal of Persson is both intriguing and vulnerable, evoking comparisons to iconic characters like Quasimodo and Nosferatu. The actor also showcases his musical talents on the accordion and even appears to hypnotize a chicken. Despite the film's static nature, which may leave viewers questioning its direction, Lavant's performance is unforgettable.'Redoubt' is a thought-provoking exploration of loneliness, fear, and community. While the film's conclusion may seem ambiguous, it ultimately presents a poignant reflection on the human condition. With its unique blend of drama and social commentary, 'Redoubt' is set to leave a lasting impression on audiences when it hits UK cinemas on March 27.

Amazon's cloud computing unit, Amazon Web Services (AWS), has confirmed that its region in Bahrain was disrupted due to drone activity. This incident marks the second time in a month that the company's operations have been affected by the war in the Middle East.An Amazon spokesperson confirmed the disruption, stating that the company is helping customers migrate to alternate AWS regions while it recovers from the incident. However, the company did not provide additional details on the extent of the damage or the expected duration of the disruption.The disruption comes after Iran's Islamic Revolutionary Guard Corps (IRGC) threatened to attack 'economic centres and banks' related to US and Israeli entities in the region. The IRGC-affiliated Tasnim news agency released a list of offices and infrastructure run by top US companies with Israeli links, including Google, Microsoft, and Oracle, which have branches in multiple Israeli cities and Gulf countries.AWS is critical for the operation of many well-known websites and government operations and is Amazon's main driver of profits. Earlier this month, AWS reported that facilities in Bahrain and the United Arab Emirates had lost power, and the company was working to transfer computing workloads to other regions.These attacks come after Iran claimed it is targeting US assets across the Gulf Arab states in retaliation for the joint attack on Iran by the US and Israel that began on February 28. Gulf states have accused Tehran of targeting civilian infrastructure, such as airports and energy facilities.

Israeli analysts are expressing a sense of disappointment and confusion following US President Donald Trump's assertion that negotiations with Iran to de-escalate the conflict are ongoing. This comes as a surprise, given Trump's previous threats to launch strikes against Iran's energy infrastructure and Tehran's denials of any negotiations taking place.The situation has left many in Israel questioning the country's role in the conflict, particularly as Prime Minister Benjamin Netanyahu had framed the war as an existential threat to Israel, with the US joining forces to combat Iran. Netanyahu has boasted of convincing the US to support Israel's stance against Iran.In a video statement, Netanyahu mentioned that Trump believed it was possible to leverage the military achievements of both the US and Israel to secure an agreement that would safeguard their vital interests. He emphasized that Israel continues to attack Iran and Lebanon, methodically dismantling Iran's missile and nuclear programs and targeting Hezbollah.Despite Netanyahu's assertions, many Israelis are aware that the war was initially presented as an effort to overthrow the Iranian government and eliminate the threat from the country. With the Islamic Republic still standing and Iran launching deadly attacks on Israel, the prospect of a negotiated end to the conflict is unsettling.Former Israeli ambassador Alon Pinkas suggested that if Trump has pushed for negotiations over Netanyahu's objections, it may indicate that the US president has realized Netanyahu may have misled him about the feasibility and speed of a victory and the viability of regime change in Iran.Political scientist Ori Goldberg described Trump's move as a defeat for Netanyahu, essentially ditching Israel. He noted that this development undermines Israel's status as a serious player that the US or other states would want to engage with.The situation highlights the complex dynamics between Israel, the US, and Iran, with analysts suggesting that even if Israel has been sidelined in current negotiations, it has still achieved significant gains in its fight against Iran. Israeli political analyst Nimrod Flashenberg noted that Israel's primary goal may have been to downgrade Iran's military capabilities, which it has accomplished in a way that ensures long-term US commitment to maintaining this status.

Israeli Finance Minister Bezalel Smotrich has called for the annexation of southern Lebanon, stating that the region's bombardment "needs to end with a different reality entirely", including a "change of Israel's borders".In a radio interview, Smotrich suggested that the new Israeli border should be the Litani River, a critical waterway in southern Lebanon. This comes as Israel continues its military operations in the area, targeting residential buildings and civilian infrastructure.The United Nations has warned that Israeli attacks may amount to war crimes, with over 1,039 people killed, including 118 children, and 2,876 wounded in Lebanon since early March. The conflict has also led to the displacement of over 1.2 million people, with many fleeing under threat of attack.The Israeli military has issued forced displacement orders for southern Lebanon and the southern suburbs of Beirut, prompting hundreds of thousands to flee. The World Health Organization has recorded at least 64 attacks on healthcare facilities, resulting in 51 deaths and 91 injuries.

A recent conversation with a guest at an academic function brought to light the public's desire for a simple, all-encompassing test for cancer. The guest, intrigued by the speaker's profession as an oncologist, inquired about the existence of an 'everything' test for cancer. The speaker's response was clear: no such test exists.The quest for early cancer detection is a significant goal in cancer medicine, with the aim of identifying the disease before it metastasizes and ensuring a cure. One company, Grail, launched a blood test called Galleri, which claims to detect a 'signal' shared by more than 50 types of cancer. This signal is identified through circulating DNA, minute fragments of cancer DNA present in the bloodstream.The Galleri test was marketed as a screening tool, with results indicating either a cancer signal detected or no cancer signal detected. However, the test failed to meet its primary endpoint in a large-scale trial conducted with the NHS, which aimed to determine if the test could reduce late-stage cancer diagnoses. Despite the company's claims of 'strong' results, the trial did not demonstrate a significant reduction in late-stage cancer diagnoses.The failure of the Galleri test highlights a crucial distinction between detecting more cancers and saving lives. Detecting cancer at an early stage does not necessarily translate to less invasive treatments or prolonged survival. Moreover, some cancers detected through screening may never have posed a lethal threat, leading to unnecessary interventions.For now, there is no blood test or total body scan that saves lives. Instead, the focus should be on modifying cancer risk factors, such as reducing processed foods, curbing alcohol consumption, quitting smoking, and engaging in regular exercise. These evidence-based approaches may not be as flashy as a single 'everything' test, but they have a proven impact on public health.

The concept of joules, named after Victorian-era physicist James Prescott Joule, has evolved significantly over time. From a simple unit to describe the effort required to pick an apple off the floor, it has grown to encompass larger units such as kilojoules, megajoules, gigajoules, terajoules, petajoules, exajoules, and now zettajoules. However, humanity's increasing energy consumption and its impact on the planet's energy balance have far outpaced our understanding and management of these growing energy levels.

Pakistan's military leadership has been playing a crucial role in attempting to broker negotiations between the US and Iran. The country's army chief, Asim Munir, recently had a call with US President Donald Trump to discuss the conflict. Diplomatic sources indicate that the US and Iran could meet for negotiations in Islamabad as early as this week to discuss an end to the war, which began almost a month ago. While Islamabad has yet to be officially confirmed as the venue, sources suggest that Tehran prefers Islamabad. Pakistani sources mention that US Vice-President JD Vance is being considered as a probable chief negotiator from the US side, rather than Trump's Middle East envoy Witkoff or Trump's son-in-law, Jared Kushner. Vance is viewed as a sceptic of the US decision to bomb Iran and has largely kept quiet on the conflict. After the phone call between Trump and Munir, Pakistan's Prime Minister, Muhammad Shehbaz Sharif, spoke to Iranian President Masoud Pezeshkian on Monday. According to an official readout of the call, they agreed on the urgent need for de-escalation, dialogue, and diplomacy. Sources suggest that Iran's parliamentary speaker, Mohammad Bagher Ghalibaf, is likely to lead any talks from the Iranian side. However, Ghalibaf has dismissed reports of talks between the two sides as 'fake news'. An Iranian diplomatic source confirmed that talks are expected this week but expressed 'zero trust' in Washington. They stated that Iran would not accept Witkoff and Kushner as negotiators for any discussions. Negotiations between the US and Iran were ongoing when the US began its bombing campaign. The Iranian regime views these negotiations as an attempt by the Trump administration to deceive Iran into thinking it wanted a diplomatic solution while planning to attack. On Monday, Trump indicated that he would be willing to halt US strikes, claiming that 'strong talks' were being held between Iranian officials and Witkoff and Kushner. Trump told reporters that they had 'very, very strong talks' and that they had 'major points of agreement, I would say, almost all points of agreement'. The US president has given a five-day deadline to an ultimatum he gave over the weekend, threatening to 'obliterate' Iran's power plants and energy infrastructure if they did not reopen the Strait of Hormuz, a crucial shipping route currently being blockaded by Iran's military. Trump's announcement of talks helped boost markets, bringing oil prices sharply down to below $100 (£75) a barrel, the lowest in days.

The ongoing conflict between the United States and Iran has sparked concerns about the motivations behind Donald Trump's continued military actions. Kenneth Roth, a Guardian US columnist and former executive director of Human Rights Watch, draws a striking parallel between Trump's approach and that of Richard Nixon during the Vietnam War. Nixon's quest for 'peace with honor' in Vietnam led to years of devastation, resulting in over 20,000 American soldiers killed and a significantly higher toll among Vietnamese, Cambodian, and Laotian civilians. Similarly, Trump's conflict with Iran appears to be driven by a desire to assert dominance and protect his political reputation, rather than a clear military objective. The article questions the rationale behind Trump's continued bombing of Iran, citing claims that Iran's ballistic missile capacity has been functionally destroyed and its nuclear program 'obliterated.' With 7,000 Iranian protesters killed in January, the Trump administration's call for regime change seems unlikely to succeed. The current fixation on Iran's blockade of the Strait of Hormuz, which carries 20% of the world's oil and gas, has led to soaring petroleum prices. Trump's threat to destroy Iran's electrical infrastructure by the end of the week, unless Tehran agrees to allow the strait to reopen, raises concerns about war crimes and humanitarian consequences. Roth suggests that a de facto ceasefire, where Trump and Benjamin Netanyahu stop bombing, could be a more fruitful path to deescalation. However, Trump's desire for 'unconditional surrender' and the Iranian regime's insistence on lifting sanctions and affirming its right to nuclear enrichment complicate negotiations. The article concludes that Trump's pursuit of 'honor' and 'victory' in the conflict may come at a significant cost to the people of Iran, the global economy, and the United States itself, echoing the lessons of the Vietnam War.
