Researchers from Stanford, Oxford and UC San Diego have demonstrated a proof‑of‑concept wearable ultrasound patch that can monitor a baby’s heart rate and blood flow continuously, aiming to reduce false alarms and missed complications in pregnancy.A Patch That Turns Ultrasound Into a Wearable SensorThe device, dubbed UPatch, adheres to the abdomen and remains operational for hours, capturing real‑time images of the foetus and umbilical cord. Unlike intermittent hospital scans, the patch records a continuous stream of data, allowing clinicians to establish a personal baseline for each pregnancy and spot deviations instantly.Trial Results Show Near‑Parity With Conventional ScansIn a study published in Nature Biotechnology, the team evaluated the patch in two cohorts:62 pregnant participants – single‑time‑point blood‑flow measurements from UPatch matched those from standard handheld ultrasound.52 women – continuous monitoring revealed dynamic fluctuations in fetal blood flow that brief scans would miss.A pre‑eclamptic case where UPatch detected severe intra‑uterine growth restriction, prompting a timely caesarean delivery and preventing stillbirth.Lead author Tom Park highlighted that the technology captures transient changes without over‑diagnosing, addressing a key limitation of current intermittent methods.Potential Shift in Prenatal Care and Global HealthSenior author Prof Sheng Xu emphasized that continuous monitoring could become a routine part of prenatal visits, especially in low‑resource settings where access to skilled sonographers is limited. Dr Antoniya Georgieva noted the broader impact: reducing stillbirth rates, providing richer data for research, and enabling earlier interventions for conditions like pre‑eclampsia.Roadmap Toward a Fully Wireless Home‑Use SystemThe current prototype is tethered to external electronics for placement, but the team is already engineering a wireless version that patients could wear during daily activities and at home. Their long‑term vision is a seamless, battery‑efficient system that integrates with tele‑health platforms, delivering real‑time alerts to clinicians wherever the mother is.

Rachel Reeves, the UK Chancellor, has valid concerns about the bond market vigilantes, who are traders seeking high-interest rates from government lending. These vigilantes target countries with uncontrolled spending, making borrowing more expensive. The UK's political instability and high debt levels have put it in their sights, along with Italy and France. The bond vigilantes are traders who pursue high-interest rates from government lending, often targeting countries with uncontrolled spending. The UK's deficit of 5-6% after the pandemic and rising interest rates on 10-year bonds have raised concerns. In early 2022, the yield on 10-year UK bonds was about 1%, but it rose to 4% two years later and reached 4.9% last week. Reeves aims to reduce the annual deficit below 2% by 2031, which received praise from Kristalina Georgieva, the IMF chief. However, Reeves can afford to ditch one unhelpful fiscal rule that requires reducing the debt-to-GDP ratio in the final year of the five-year economic forecasts. This rule hinders long-term investments, such as extra defence spending, which could begin in four to five years. An open trading economy like the UK must play by the rules of international bond markets. Nevertheless, there is room for manoeuvre. By revising this fiscal rule, Reeves can support vital investments without violating existing commitments. The UK's economic stability and ability to defend itself depend on making sensible decisions, not adhering to outdated rules.

Analysts warn that the world is confronting the most severe energy shock since the 1970s, a looming global recession and a renewed surge in living‑cost pressures that are hitting the most vulnerable households hardest.Against a backdrop of sweltering Washington heat, the atmosphere at the International Monetary Fund’s spring meetings shifted dramatically as delegates confronted the fallout from the Iran war. The usual optimism about rising living standards was replaced by a palpable sense of unease.IMF Managing Director Kristalina Georgieva addressed finance ministers and central‑bank governors, noting that “some countries are in panic” and urging that “the sooner it ends, the better for everybody.”Such gatherings are rarely venues for open geopolitical confrontation. Yet, as a record‑breaking April heatwave baked the capital, the mounting economic damage from the conflict could no longer be ignored.During a G20 breakfast that included U.S. Treasury Secretary Scott Bessent and outgoing Fed Chair Jerome Powell, participants described the mood as somber, with frank discussions about the war’s ramifications.Former IMF deputy managing director Mohamed El‑Erian likened the session to a “twilight‑zone meeting,” identifying three looming shadows: the overall health of the global economy, the disproportionate impact on lesser‑discussed nations, and the paradox that the United States, as the war’s initiator, would suffer comparatively less.British Chancellor Rachel Reeves started her day with a jog alongside counterparts from Spain, Australia and New Zealand on the National Mall, posting an Instagram selfie captioned, “Friends that run together – work together.” The image underscored her resolve to confront the war’s economic fallout.Reeves had earlier condemned the conflict as a “mistake” and “folly,” arguing that the war had not enhanced global security and was driving up energy prices for UK families and businesses.In a one‑on‑one with Bessent near the White House, Reeves emphasized the urgency of the situation, noting that the UK, like many other nations, was feeling the pain of higher energy costs triggered by the conflict.Despite the tension, the UK and the United States continue to share deep interests in artificial intelligence, financial services and trade, though the British government signalled little tolerance for the Iranian regime.The IMF’s own warning that the war could precipitate a global recession singled out the United Kingdom as the “biggest G7 casualty,” highlighting the stakes for British growth forecasts.Observers noted Reeves’s vocal stance, recalling earlier disagreements between Bessent and European Central Bank President Christine Lagarde that had remained behind closed doors.A cocktail reception at the British ambassador’s residence brought together senior diplomats and financiers—including Bank of England Governor Andrew Bailey and Barclays CEO CS Venkatakrishnan—where transatlantic friction was a hot topic, just weeks before King Charles’s state visit to the United States.Meanwhile, revelations about former ambassador Peter Mandelson’s vetting process added another layer of political strain for the UK government.Before the war, the IMF agenda focused on global cooperation, AI adoption, job creation and poverty eradication. The conflict has now complicated each of these priorities, especially the goal of coordinated international action.Former UK Foreign Secretary David Miliband observed that many nations are now “hedging against American decisions,” acknowledging the United States’ outsized role—about 25% of the global economy—while noting its recent retreat from several forums.The irony was not lost on participants: the meetings were held in institutions born out of U.S. leadership after World War II to prevent the economic chaos of the 1930s, yet they now convene amid a war that threatens similar turmoil.Economists also recognized that real policy leverage sits “two blocks away,” behind the security cordons surrounding the White House, casting doubt on the ability of the IMF and World Bank to influence the conflict directly.Amid the uncertainty, the rapid growth of AI—exemplified by Anthropic’s Mythos model—offers a glimmer of economic resilience, but most countries cannot afford to sever ties with the United States entirely.El‑Erian summed up the dilemma: “People want to go long the private sector and short the mess, but it’s almost impossible to do.”

The International Monetary Fund (IMF) and the World Bank have announced the resumption of ties with Venezuela under the country's interim leader, Delcy Rodriguez. This move comes after a period of severed relations that began in 2019 due to international disputes over the legitimacy of Venezuela's leadership. The IMF and World Bank had cut ties with Caracas in 2019 amid a split in the international community over whether to support Nicolas Maduro or Juan Guaido as the country's rightful leader following disputed presidential elections. IMF Managing Director Kristalina Georgieva stated that the institution had resumed dealings with Venezuela under Rodriguez's administration, guided by the views of its members. This step is expected to ultimately benefit the Venezuelan people. The World Bank followed suit, announcing that it would re-engage with Venezuela based on the outcome of the IMF's decision-making process. The bank had last made a loan to Caracas in 2005. These announcements come several weeks after the United States President's administration lifted sanctions on Rodriguez, further conferring legitimacy on her leadership. Rodriguez welcomed the announcements, calling it a significant achievement for Venezuelan diplomacy. Venezuela has one of the highest debt burdens in the world, with total external liabilities estimated at more than $150bn. The resumption of ties with the IMF and World Bank clears the way for Venezuela to request financial assistance if necessary to shore up its finances. In 2020, the IMF had rejected Venezuela's request for an emergency loan of $5bn to help fund its response to the COVID-19 pandemic, citing the lack of international consensus on Maduro's legitimacy. Venezuela has been a member of the IMF and World Bank since 1946.

The collapse of talks between the US and Iran has sent shockwaves through global markets, fuelling fears of a prolonged energy crisis and rising inflation. The failure to reach a peace deal has left large numbers of oil tankers stuck in the Persian Gulf, with oil prices fluctuating wildly in response to the uncertainty.US Vice-President JD Vance has blamed the collapse of the talks on Tehran's refusal to abandon its nuclear weapons programme, while Iranian sources have hit back at what they describe as 'excessive' demands from Washington. The stalemate has raised concerns about the long-term impact on the global economy, with governments and central banks warning of higher inflation and interest rates.Mohamed El-Erian, an adviser to Allianz, has cautioned that uncertainty will continue to dominate assessments of the financial impact from the conflict. 'Absent a swift resumption of negotiations, the immediate reaction of financial markets when they open for the trading week will be to push oil prices higher and borrowing costs higher,' he said.The International Monetary Fund and World Bank's spring meetings in Washington will focus on the war's impact on the global economy, with the IMF's managing director, Kristalina Georgieva, indicating that the fund will present three scenarios predicting lower economic growth and higher inflation. The IMF is also expected to highlight the impact on vulnerable economies.In the short term, oil prices have ended the week lower, with Brent crude at $94.26 a barrel and West Texas Intermediate crude at $95.63 a barrel. However, global stock markets have rebounded after a temporary ceasefire was announced, with the S&P; 500 close to its level before the US-Israeli attacks on Iran began.

The world's finance ministers and central bank governors are gathering in Washington for the half-yearly meetings of the International Monetary Fund and the World Bank, with the global economy in a perilous spot. The US-Israeli war on Iran, coming soon after the Covid pandemic and Russia's invasion of Ukraine, has triggered significant economic turbulence.Even if a durable peace deal in the Middle East can be reached, there will still be permanent economic scars. The conflict has caused damage to infrastructure, heaping further pressure on already struggling households. This is the biggest energy shock of the modern age, with oil and gas prices surging, inflation rising, and borrowing costs increasing.The IMF has said it will cut its growth forecasts for 2026 when it publishes its flagship world economic outlook. In every scenario, growth is slower and inflation higher. Households worldwide will feel the pain, with the world's poorest bearing the brunt.The fund's managing director, Kristalina Georgieva, has urged officials to work together, warning that "go-it-alone actions" may have appeal but would ultimately make matters worse. The IMF cautions that any energy support should be targeted and temporary to limit the costs of blanket support and avoid stoking inequality.For central banks, the fund urges them to remain vigilant, with financial markets expecting interest rates to be kept on hold or raised to prevent high inflation from becoming entrenched. The economic problems are interlinked with political instability, making it a challenging situation for governments worldwide.

The recent ceasefire between the United States, Israel, and Iran has brought a fragile calm to the region, but experts warn that energy prices may take months to normalize. The conflict had a significant impact on global oil and gas supplies, particularly through the Strait of Hormuz, a critical waterway through which 20% of the world's oil and gas exports pass.Iran's response to US-Israeli attacks included choking off the Strait of Hormuz and attacking energy infrastructure in several Gulf countries. This led to soaring prices for energy and byproducts like helium, as well as fertilizers that rely on these inputs, affecting sowing seasons and consumers worldwide, especially in developing countries.Experts stress that a predictable and stable flow of cargo through the strait is needed before markets can stabilize. Currently, only a trickle of vessels are passing through, with five vessels crossing on Wednesday and seven on Thursday, down from 120-140 ships per day before the conflict.Rockford Weitz, a professor at The Fletcher School at Tufts University, described the situation as 'the biggest disruption in the history of global oil markets.' He emphasized that normalization will take time and requires collaboration among global powers and regional players.Additionally, concerns remain about Iran charging toll fees and skyrocketing insurance fees, which could keep oil prices high. However, experts agree that these fees are not the primary cost drivers.The International Monetary Fund (IMF) has warned of a looming inflation crisis and plans to downgrade its forecast for the world economy. Kristalina Georgieva, IMF managing director, stated that growth will be slower, even if the new peace is durable.For now, oil prices are expected to remain higher than pre-war levels due to the overhang of greater risk premium of supplies out of the Gulf. The situation remains uncertain, with experts closely watching for any side deals, such as a potential agreement between Iraq and Iran, which could impact oil production and prices.

The International Monetary Fund has cautioned that the US‑Israel war on Iran could ignite a new wave of global inflation, jeopardising the outlook for world growth even if the current cease‑fire endures. IMF Managing Director Kristalina Georgieva announced on Thursday that the Fund will lower its growth projection for the global economy at next week’s IMF‑World Bank Spring Meetings, stating that the conflict has turned a potential upgrade into a growth downgrade. Earlier this year the IMF had lifted its forecast to 3.3 % growth for the 191‑member economies. That optimism evaporated after the war erupted on 28 February, driving up oil and natural‑gas prices, damaging energy infrastructure such as refineries and tanker terminals, and disrupting fertilizer shipments essential for global agriculture. Georgieva warned that the conflict is eroding business and consumer confidence and urged member nations to “get your house in order” as heightened defence spending adds further strain to the world economy. She also expressed confidence that the IMF will secure U.S. congressional approval this year for a 50 % increase in quota‑based lending resources, unlocking more of its roughly $1 trillion lending capacity. The United States, the Fund’s largest shareholder, would thereby provide crucial financial reassurance amid uncertain future developments. In a newly released report, the IMF estimated that countries directly involved in armed conflict typically see output fall by about 3 % at the outset, accumulating to roughly 7 % losses over five years. However, the study noted that economies like the United States may avoid severe economic damage because the fighting does not physically affect their own territory. Central banks are also on alert. Georgieva emphasized that “the central bank cannot afford to let inflation spiral out of control,” a statement that precedes the U.S. Federal Reserve’s two‑day policy meeting scheduled for 28–29 April, where interest‑rate decisions will be made amid political pressure from President Trump to lower rates. Other monetary authorities, including the Bank of Mexico, warned that the Middle‑East turmoil could push inflation higher in Latin America’s second‑largest economy, underscoring the broader spill‑over risks of the conflict.

In a stark address delivered as the cease‑fire in the Iran conflict teetered, IMF Managing Director Kristalina Georgieva warned that the war will leave a permanent scar on the global economy, slowing growth beyond the IMF’s original projections for 2026. Georgieva noted that, had the hostilities not erupted six weeks ago, the Fund would have been poised to raise its 2026 growth outlook. Instead, even the most optimistic scenario now entails a downgrade, and a swift return to pre‑war conditions appears unlikely. The uncertainty surrounding the cease‑fire—exacerbated by divergent positions of Washington and Tehran—has already pushed oil prices higher, reflecting fears of continued disruptions to shipments through the Strait of Hormuz, a vital conduit for world energy supplies. According to the IMF’s upcoming World Economic Outlook, the conflict’s “scarring effects” will translate into lower living standards worldwide. The Fund had previously forecast global growth of 3.1% in 2026, a modest slowdown from 3.2% in 2025, buoyed by a tech‑driven investment surge. Georgieva emphasized that the war arrived when the economy was riding “considerable momentum” from technology investment and supportive financial markets. She outlined the mechanisms of damage: damaged infrastructure, supply‑chain interruptions, eroded confidence, and prolonged uncertainty over oil and gas production in the region. These factors will depress growth regardless of whether a peace agreement is ultimately reached. Georgieva highlighted that the most vulnerable will be net oil‑importing nations, poorer economies and small island states, which stand to feel the brunt of higher energy costs and reduced trade flows. She urged governments to avoid unilateral measures such as export bans or price controls, warning that such actions could "pour gasoline on the fire" and further destabilise markets. With many countries already carrying elevated debt levels and higher borrowing costs, the IMF chief called for targeted, temporary assistance to protect the most at‑risk households. She cautioned against broad tax cuts or blanket energy subsidies, which could stoke inflation and strain fragile public finances. Central banks, she added, should keep policy rates steady while remaining ready to act against inflationary pressures. Bank of England Governor Andrew Bailey, who also chairs the Financial Stability Board, echoed the IMF’s concerns, describing the conflict as a "very big shock" that has heightened market volatility. He stressed that the situation remains fluid and that policymakers must stay vigilant. Overall, the IMF’s message is clear: the Iran war will reshape the global growth trajectory for the foreseeable future, and coordinated, prudent policy responses are essential to mitigate its lasting impact.
