The Pavlovian Paradox: Mosquitoes Learn to Associate DEET with FoodFor decades, the efficacy of DEET (N,N-diethyl-meta-toluamide) has been attributed solely to its chemical properties, which are believed to either repel insects or block their ability to detect humans. However, a new study led by Professor Claudio Lazzari from the University of Tours suggests a more complex behavioral interaction. The research indicates that mosquitoes can learn to associate the scent of DEET with the presence of a blood meal, effectively turning a repellent into a lure through a process similar to Pavlovian conditioning.Experimental Evidence: From Repellent to LureThe study, published in the Journal of Experimental Biology, involved trapping mosquitoes and presenting them with warm blood that was just out of reach. The insects were simultaneously exposed to DEET. The results demonstrated a significant shift in behavior:Trained Group: 60% of mosquitoes that fed while exposed to DEET subsequently attempted to bite when exposed to the repellent alone.Control Groups: Significantly lower percentages were observed in untrained insects (17%) and those with prior exposure to DEET alone (13%).In a real-world test, nearly 60% of the trained mosquitoes attempted to bite a researcher's DEET-treated hand, whereas untrained mosquitoes universally targeted the untreated hand.Redefining Insect Control StrategiesThis discovery represents a significant shift in our understanding of how repellents work. It suggests that the reaction to DEET is not merely a chemical aversion but can be modified by experience. Experts, including Dr. Nina Stanczyk of ETH Zürich, emphasize that while the learning ability of mosquitoes is impressive, the implications for public health are nuanced. The study highlights that repellents may function differently depending on the context of the mosquito's previous interactions with humans.Future Outlook for TravelersDespite the alarming findings, experts urge travelers not to abandon DEET. The consensus is that this phenomenon occurs under specific laboratory conditions and is unlikely to happen frequently in the wild due to the variability of repellents encountered during different blood meals. The key takeaway for the future is the importance of consistent application. As noted by the researchers, the risk of association is highest when the repellent starts to wear off, reinforcing the need for regular reapplication to maintain protection.

The Call for Tax Cuts Wes Streeting has called for national insurance tax cuts for businesses, and for the government to drill for oil and gas in the North Sea. The former health secretary and Labour leadership candidate told the Sunday Times there should be a “targeted reduction” of employers’ national insurance contribution as a way to “actively incentivise” hiring, particularly of young people. The Impact of National Insurance Rate Increase In 2024, the rate of national insurance paid by employers was increased from 13.8% on each employee’s salary to 15%. The starting threshold it applied to was lowered from £9,100 to £5,000. The measure aimed to raise £25bn a year, but businesses said it disincentivised hiring lower-paid and part-time staff. Youth Unemployment Concerns A report this week by the former cabinet minister Alan Milburn said a lack of hospitality jobs was contributing to high youth unemployment in Britain. It pointed to a halving of vacancies in the hospitality industry over the past four years alone. Analysis shows Britain has the third-highest rate of 16- to 24-year-olds who are not earning or learning among rich European countries. The Government's Response Pat McFadden, the work and pensions secretary, suggested he disagreed with this view. Speaking on Sky News on Sunday morning, he defended the government’s record, saying that businesses already did not have to pay employers’ national insurance for workers under 21. The Future of North Sea Drilling There has been a debate within Labour about whether to grant drilling consents for the giant oil and gas fields Rosebank and Jackdaw. Though there was a commitment not to give out any more licences for fossil fuels in Labour’s manifesto, there is a loophole that could be exploited; Rosebank and Jackdaw were given exploration licences by the previous Conservative government. They just need consent to drill. Ed Miliband's Decision Ed Miliband, the energy secretary, is due to make a decision on these oil and gas fields in coming weeks. He, along with the North Sea Transition Authority, have to decide whether the drilling would be consistent with the UK’s climate commitments.

Executive Summary: Trump Sends Revised Iran Deal FrameworkPresident Donald Trump has returned a new proposal to Iran that tightens several conditions of a deal intended to end the ongoing US‑Israel war on Iran. Media outlets including The New York Times and Axios say the revisions emphasize stricter controls on Iran’s nuclear material and the reopening of the strategic Strait of Hormuz.Revised Deal Terms Emphasize Nuclear Material Controls and Hormuz AccessThe updated framework, described as a “toughening” of the original terms, was sent back to Tehran after a White House Situation Room meeting on May 30, 2026. While the exact language of the changes was not disclosed, officials note that Trump wants to reinforce points he deems critical, such as:Ensuring Iran never develops nuclear weapons.Reopening the blockaded Strait of Hormuz, a key oil transit route.Clarifying procedures for handling Iran’s existing nuclear material.A senior U.S. official warned that Iran could need up to three days to formulate a response, noting the logistical challenges faced by Iranian negotiators.Quantitative Context: Oil Flow Through Strait of Hormuz and Timeline Estimates20 % of the world’s oil supply transits the Strait of Hormuz, making its reopening a high‑stakes demand.Iranian officials indicated a response window of three days, though U.S. officials suggested the overall process could extend from a few days to a week or more.The war began after the U.S. and Israel attacked Iran on February 28, 2026, and no final deal has been signed to date.Geopolitical Ramifications for US‑Israel‑Iran RelationsThe tightened terms could lengthen negotiations, potentially delaying any cessation of hostilities. Iran’s military headquarters has reiterated control over the Strait, warning that non‑compliant vessels may be targeted, which raises the risk of broader maritime confrontations. Meanwhile, U.S. officials remain publicly committed to a deal that prevents nuclear weapon development while safeguarding global oil flows.Outlook: Potential Scenarios for Deal FinalizationIf Iran accepts the revised framework within the projected response window, a cease‑fire could be announced within a week, easing regional tensions.Should negotiations stall, the war could continue, with heightened naval activity in the Strait of Hormuz affecting global oil markets.Extended delays may prompt the U.S. to reconsider its diplomatic approach, possibly escalating military posturing or seeking alternative multilateral pressure on Tehran.

The Lead: Beach Panic Amid Hezbollah StrikesBeachgoers in northern Israel experienced a terrifying moment of panic as Hezbollah launched strikes in the area, forcing people to flee for safety. The incident underscores the persistent security challenges faced by communities near the Israel-Lebanon border.The Event Details: Hezbollah's Beachfront AttackAccording to reports from northern Israel, Hezbollah targeted areas close to popular beaches, causing immediate panic among civilians enjoying a day by the sea. The strikes prompted emergency services to respond as people scrambled to find shelter from the incoming attacks. This represents a significant escalation in the cross-border tensions between Israel and the Lebanese militant group.The Impact Analysis: Regional Security ImplicationsThe beach attack highlights the vulnerability of civilian infrastructure in conflict zones and demonstrates how Hezbollah continues to maintain capabilities to strike Israeli territory. This incident could potentially trigger a broader military response from Israel, further destabilizing an already volatile region. The attack also sends a message to Israeli citizens living in northern areas that they remain within range of hostile forces.The Prediction: Escalation or De-escalation?Following this beach attack, analysts predict several possible scenarios. The Israeli military may respond with targeted strikes against Hezbollah positions in Lebanon. Alternatively, regional mediators might step in to prevent further escalation. The coming days will be critical in determining whether this incident represents a temporary flare-up or the beginning of a more sustained conflict between the two adversaries.

The LeadThe Democratic Republic of Congo is grappling with another Ebola outbreak, with women bearing the brunt of the crisis. As frontline caregivers, healthcare workers, and community leaders, women are facing heightened risks while simultaneously shouldering increased responsibilities in households and communities affected by the deadly virus.The Event DetailsThe latest Ebola outbreak in DRC marks another chapter in the country's ongoing battle with the virus since its first appearance in 1976. This particular outbreak has been particularly challenging due to the complex security situation in the affected regions, which has hampered response efforts. Health officials report that women constitute approximately 60% of all Ebola cases in this outbreak, a stark statistic that highlights gender disparities in health crises.The Data AnalysisAccording to recent reports from the World Health Organization (WHO), women account for a disproportionate number of Ebola cases in the DRC. Key statistics include:Women make up 58-62% of all confirmed Ebola cases70% of Ebola deaths among healthcare workers are womenWomen represent 65% of all caregivers for Ebola patientsIn some affected regions, women's infection rates are 30% higher than men'sThe Impact AnalysisSeveral factors contribute to women's heightened vulnerability in this Ebola outbreak. As primary caregivers in families and communities, women have increased exposure to infected patients. Traditional gender roles often place women in positions of caring for sick relatives at home before seeking medical help, increasing their risk of exposure. Additionally, limited access to healthcare information and resources disproportionately affects women in many DRC communities, where cultural norms may restrict women's mobility and decision-making power.The outbreak has also exacerbated existing gender inequalities. Women are more likely to become economically vulnerable as markets close and traditional livelihoods are disrupted. Many women have reported increased gender-based violence and reduced access to essential reproductive healthcare services as resources are diverted to Ebola response efforts.The PredictionHealth experts predict that without targeted interventions, women will continue to bear the disproportionate burden of this Ebola outbreak. Future response efforts must incorporate gender-sensitive approaches that address the specific needs and vulnerabilities of women. This includes ensuring women have equal access to healthcare information, involving women in decision-making processes, and providing support systems that account for the unique challenges women face in health crises.The DRC government, with support from international organizations, is beginning to implement gender-responsive strategies, but much work remains to be done. As the outbreak evolves, monitoring gender disparities will be crucial to ensuring an effective and equitable response that protects all community members, particularly those most vulnerable.

Iran has reasserted its control over the Strait of Hormuz, warning that foreign commercial and military vessels will be targeted if they do not comply with regulations governing passage through the strategic waterway.Iran's Assertion of Maritime SovereigntyThe announcement came after the United States signalled that President Donald Trump was close to a decision on a potential deal with Iran, though Tehran denied an agreement had been reached. The operational headquarters of Iran’s armed forces, Khatam al-Anbiya Central Headquarters, stated that the management of the Strait is exercised with full authority by the Islamic Republic.“All ships, commercial vessels, and tankers are only required to travel through the designated routes and obtain permission from the Islamic Revolutionary Guard Corps [IRGC] Navy,” the statement added. It warned that any violation would seriously jeopardise the security of their traffic.The High-Stakes Diplomatic StandoffThe situation is defined by a clash of demands. While the US seeks a deal ensuring Iran never develops nuclear weapons, Iran is demanding the immediate release of $12bn in frozen assets before proceeding to the next phase of negotiations.US Position: President Trump stated Tehran would remove mines from the strait and end its closure with “no tolls,” while the US would lift its blockade.Iranian Position: Adviser Mohsen Rezaei accused the US of “betraying diplomacy” and making excessive demands.Regional Military EscalationMilitary posturing remains high as both sides prepare for a potential breakdown in talks. Pentagon Chief Pete Hegseth stated that Washington was “more than capable” of restarting the war if a satisfactory deal is not reached.On the ground, tensions escalated with the shooting down of a drone described as belonging to the “US-Zionist enemy” by Iranian air defences. Meanwhile, US Central Command (CENTCOM) continues to warn Iranian ships against crossing the blockade line.Navigating the Path to a DealWith President Trump’s “final determination” pending, the coming days are critical for global stability. The stalemate over the $12bn assets and the reopening of the strait suggests that a diplomatic resolution is not imminent, leaving global markets on edge regarding the flow of oil through this critical chokepoint.

The Surge in Anti-Foreign Business ViolenceSouth Africa is currently facing a wave of violent attacks targeting foreign-owned shops and businesses, with reports of looting, arson, and intimidation spreading across several provinces. The violence, which appears to be fueled by xenophobic sentiments, has raised serious concerns about the safety of immigrant entrepreneurs and the stability of local markets.Escalating Attacks on Immigrant-Owned EnterprisesThe recent spate of violence has seen numerous foreign-owned retail establishments being targeted, with many shopkeepers reporting threats and physical attacks. Witnesses describe coordinated attacks where groups of individuals descend on shopping areas, systematically targeting businesses owned by immigrants from other African nations. South African authorities have deployed additional police forces to affected areas, but the violence continues to flare up in different regions.Economic Toll of the UnrestThe attacks are taking a significant economic toll, with estimates suggesting millions of dollars in damages to foreign-owned businesses. Shop owners report complete losses of inventory and property, with many fearing they may never be able to reopen. Local economies in affected areas are also suffering, as these businesses often serve as vital retail hubs for surrounding communities, providing essential goods and services.Regional Implications and Social TensionsThe violence against foreign-owned businesses is exacerbating already strained social relations in South Africa. The attacks reflect deep-seated economic frustrations and xenophobic attitudes that have been building for years. This situation threatens South Africa's reputation as a relatively stable economy in the region and could impact diplomatic relations with neighboring countries whose citizens are being targeted.Path Forward for Business Safety and Community RelationsExperts predict that without immediate intervention, the violence could escalate further, potentially leading to broader social unrest. Government officials are calling for dialogue between local communities and foreign business owners, while also addressing the root economic grievances that fuel such attacks. Long-term solutions may include better economic opportunities for local populations and strengthened protection for all businesses regardless of ownership nationality.

The Strategic Retreat: Trump's Iran Policy EvolutionAfter weeks of stop-start negotiations, the US and Iran now reportedly stand on the verge of a deal to end the fighting, with the most immediate consequence being the reopening of the Strait of Hormuz. This development marks a dramatic shift from President Trump's initial maximalist goals, which included regime change, destruction of Iran's nuclear program, and elimination of its regional proxies.The Peace Deal Terms: Ceasefire and NegotiationsThe reported memorandum of understanding, reached with the help of Pakistani and Qatari mediators, would extend the current ceasefire for 60 days, during which negotiations would take place on the two-decades-old dispute over Iran's nuclear program. Iran's closure of the strategically vital waterway—conduit of 20% of the world's crude oil supplies before the war started—has had a baleful effect on the US economy, sending gasoline prices soaring and leading to a shortage of fertilizer that threatens food supplies and prices.From Maximalism to Reality: Strategic ImplicationsThe specter of fudged compromise illustrates how Trump's maximalist goals have shrunk—and in the eyes of some commentators, been defeated. Robert Kagan, a foreign policy fellow at the Brookings Institution, wrote in The Atlantic that "Trump's endgame is surrender," adding that the president "no doubt hopes that he can slip away without Americans noticing the magnitude of this defeat." Despite Trump's initial declarations that only "unconditional surrender" would be acceptable, Iran's military capabilities remain largely intact, with analysts estimating that 70% of their ballistic missiles and 70-80% of drones are still operational.Regional Impact: Shifting Power DynamicsThe evolving situation represents a significant shift in Middle Eastern power dynamics. Contrary to Trump's expectations, the Islamic regime remains intact despite targeted assassinations of its leaders. While Trump publicly proclaims successor leadership figures to be "more reasonable" than before, the regime appears to be more unyielding than ever. Mojtaba Khamenei, who succeeded his father as supreme leader, was recently quoted as predicting that Israel would cease to exist by 2040. The limited military success of Trump's war of choice is now forcing him to address it through the pragmatic type of compromise that he and his rightwing allies once lambasted Obama for.Future Outlook: Trust Deficits and Political ChallengesRobert Litwak, an international relations professor at George Washington University, noted that Trump is being forced to confront a "persistent tension" in US post-cold-war policy between "transformational" approaches meant to topple rogue states and "transactional" agreements intended to change their behavior. "He's in a box because a transformational outcome is not possible," said Litwak. Trump faces significant political challenges in securing support for what essentially amounts to a variant of the JCPOA that he previously opposed. His credibility deficit with Iran, exemplified by his tendency to reverse positions on Truth Social, further complicates negotiations. As Vali Nasr, an international relations professor at Johns Hopkins University, noted: "The reason [Iranians] don't [sign on] is because they don't trust him. It has nothing to do with ideology or fractured leadership or the midterms. It's because of his record."

The Failed Dealmaker: Trump's Iran Dilemma For weeks, Donald Trump has tried to find a way to end the war he started with Iran – a deal that would allow him to declare victory and move past the conflict before it causes severe damage to the global economy and sinks Republican chances in the US midterm elections. But the self-proclaimed master dealmaker can't seem to stop sabotaging his own negotiations or to acknowledge that Iran is now in a better position to demand concessions than it was before the war. Strategic Missteps: From Military Action to Negotiation Deadlock Over the Memorial Day holiday, Trump skipped his eldest son's wedding in the Bahamas and canceled plans to spend the weekend at his New Jersey golf club. The last-minute changes heightened speculation that Trump was ready to unveil a deal to end the war. Trump then announced that he would hold a cabinet meeting at Camp David, the presidential compound in Maryland that has been the site of historic diplomatic summits. But that meeting was moved back to the White House, as it became clear that Trump had not been able to close a deal he could announce with great fanfare. The Art of the Deal: Trump's Negotiation Paradox Why has an agreement eluded the business titan who wrote the bestselling 1987 book The Art of the Deal? Trump admires strongman leaders and is loth to project any sign of weakness – and he's afraid of reaching a deal with Iran that makes him look weak. The president is also sensitive to criticism that any agreement he negotiates will be worse for the US than the 2015 nuclear deal between Iran and six world powers, which was brokered by Barack Obama's administration. Leverage Reversed: How Iran Gained the Upper Hand Trump's main problem is that Iran has more leverage than he does – and Iranian leaders are well aware of that advantage. On 28 February, Trump launched a joint US-Israeli war against Iran, killing the supreme leader, Ayatollah Ali Khamenei, and other top military and political officials. But Iran retaliated with missile and drone strikes against US military bases across the Middle East, and it targeted the energy infrastructure of its Gulf neighbors. Iran also deployed its most effective economic weapon: it closed the strait of Hormuz, through which more than a fifth of the world's oil supply passed each day. Economic Fallout: Global Disruption and Rising Oil Prices The closure of the Strait of Hormuz – along with Iranian attacks on pipelines and gas fields in Kuwait, Saudi Arabia, Qatar and the United Arab Emirates – disrupted the global economy and increased oil prices. In the US, average gas prices have jumped by 50%, up to nearly $4.50 per gallon, since Trump launched the war. Trump and his ally, the Israeli prime minister, Benjamin Netanyahu, could not topple the Islamic regime that rose to power after Iran's 1979 revolution. Instead, they ended up strengthening it – by allowing Tehran to deploy its geographic control of the strait of Hormuz into a weapon that could instigate a global energy crisis and a worldwide recession. The Emerging Deal: Limited Concessions and Unresolved Issues The emerging deal is focused on solving a problem that didn't exist before Trump started this war: fully reopening the strait of Hormuz to commercial shipping so that oil prices can stabilize. Under a draft agreement being circulated to US allies, Washington would also lift its blockade of Iranian ports and allow Tehran to access about $12bn in frozen assets. Once again, Trump seems to be aiming for a limited deal with Iran that defers the most difficult questions to future talks, which could drag out for months or even years. Iran's Resilience: Military Strength Preserved In some ways, Iran has emerged stronger after a war intended to decimate its military capabilities. A CIA report sent to Trump earlier this month found that Tehran had managed to retain a significant part of its missile capabilities. The analysis said Iran preserved about 70% of its prewar stockpile of missiles and about 75% of its mobile launchers. The report also concluded that Iran was more resilient than US officials had claimed, and it could survive a naval blockade for months. Political Calculations: Midterm Elections and Trump's Dilemma At his cabinet meeting, Trump said he didn't care about the midterm elections and wasn't in a rush to reach a deal. "It's got to be perfect," Trump told reporters, adding: "I didn't do this to get a crummy agreement." Despite his weak position, Trump insists that he will strike a better deal with Iran than the one negotiated by the Obama administration in 2015. That agreement provided Tehran with relief from international sanctions in exchange for limits on its nuclear enrichment. The Unintended Consequences: Strengthening the Adversary Trump could have avoided starting a regime-change war that failed, leaving the world to deal with its consequences. Instead, the master negotiator handed Iran a new economic weapon – and more leverage to extract a favorable deal. The worst thing you can possibly do in a deal is seem desperate to make it. That makes the other guy smell blood, and then you're dead. Trump wrote in his famous book. The best thing you can do is deal from strength, and leverage is the biggest strength you can have.
