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 LeadA daily pill has shown remarkable results in doubling survival time for patients with pancreatic cancer, the world's deadliest form of the disease. According to clinical trial results presented at the American Society of Clinical Oncology's annual meeting, this breakthrough treatment represents a potential revolution in how we approach a cancer that has seen limited progress for decades.The Breakthrough Drug: DaraxonrasibThe drug in question, daraxonrasib, works by targeting a protein called Kras that fuels nearly all pancreatic cancers. This mechanism represents a significant advancement in treatment strategy, as Kras has been notoriously difficult to target effectively. The drug functions as a Ras(On) multi-selective inhibitor, capable of turning off the Kras protein to stop cancer growth regardless of which variant is present.Impressive Trial ResultsIn the clinical trial involving 500 patients with advanced pancreatic cancer, the results were striking. Those who took daraxonrasib lived an average of 13.2 months, compared to just 6.6 to 6.7 months for patients who received chemotherapy. This represents a near doubling of survival time, with the added benefit of fewer side effects compared to traditional chemotherapy treatments.Industry Impact and Expert ReactionsThe findings have been hailed as a "gamechanger" and "grand slam" by experts in the field. Dr. Rachna Shroff, chief of oncology at the University of Arizona Cancer Center, described the results as "landscape-changing" and "unprecedented survival." When she first read the trial results, conducted by researchers at the Dana-Farber Cancer Institute in Boston, she wept, noting the profound impact this could have on patients after 16 years of treating pancreatic cancer.Dr. Julie Gralow, Asco's chief medical officer, echoed these sentiments, calling the study a "home run" and suggesting it was actually a "grand slam" in terms of its significance.The Ras RevolutionOver 90% of patients with the most common form of pancreatic cancer, pancreatic ductal adenocarcinoma (mPDAC), have a mutation in the Kras gene. This discovery has long been considered the "holy grail" in cancer research, particularly for pancreatic cancer where the mutation is nearly ubiquitous and an early driver of cancer growth.Paula Hanford, chief executive of UK-based Pancreatic Cancer Action, called this one of the most significant developments in treatment she had ever seen. Similarly, Anna Jewell, director of services, research and innovation at Pancreatic Cancer UK, described the results as "exciting," noting that the drug gives patients "months more precious time with their loved ones."Future Outlook and ApplicationsThe success of daraxonrasib opens doors for similar treatments targeting Ras genes in other cancers. Experts at the conference noted that because Ras genes fuel various types of cancer, there is hope for breakthroughs in treating lung and colon cancers as well, with similar drugs already in development for these conditions.However, challenges remain in ensuring these promising treatments become widely available to patients. As Jewell pointed out, tragically half of all people with pancreatic cancer die within just three months of diagnosis, making the rapid implementation of such treatments crucial.

Brighton & Hove Albion Women will take the field against Manchester City Women at Wembley on 31 May 2026 for the Women's FA Cup final. City aim to complete a first-ever double, while Brighton chase their inaugural major trophy, playing under the emotional weight of the recent passing of Rado Vidosic, the club’s former head of coaching. Brighton Chasing First Major Trophy Amid Tribute to Late Coach Rado Vidosic The match carries deep personal significance for Brighton. Rado Vidosic, who died from cancer four months earlier, was a pivotal figure in the club’s development. His son, Dario Vidosic, who grew up watching Wembley finals, now leads the team onto the pitch, honoring his father's legacy. Match Timing, Historical Context and Key Figures Kick‑off: 3:00 pm BST (13:00 GMT) City’s ambition: First domestic double in club history. Brighton’s goal: First Women’s FA Cup title since the competition’s inception. Key players: Khadija “Bunny” Shaw (City) – recently secured a four‑year contract extension; Ruth Keenan (Brighton) – leading scorer this season. Historical note: City have won the league this season; Brighton have never lifted the cup. Potential Shift in Women’s Football Power Balance A Brighton victory would signal a breakthrough for clubs outside the traditional powerhouses, potentially encouraging greater investment in smaller teams. Conversely, a City win would cement their dominance and could accelerate the professionalisation of the women's game across England, attracting more sponsors and media attention. What the Result Could Mean for Both Clubs If City wins: Reinforces their status as the premier English women’s side, boosting brand value and likely influencing future player recruitment. If Brighton wins: Provides a morale boost, validates the club’s development pathway, and may spur increased fan engagement and funding. Long‑term outlook: Either outcome will shape the narrative for the 2026‑27 season, affecting league dynamics, TV rights negotiations and grassroots participation.

Iga Swiatek's Unhappy Birthday at French Open Iga Swiatek's 25th birthday celebrations turned sour at the French Open on Sunday as the former champion lost 7-5, 6-1 in the fourth round to the Ukrainian 15th seed Marta Kostyuk, her challenge for a fifth title ending just when she had looked to be rediscovering her rhythm. The Match Turning Point There was little to separate the duo in the early exchanges as they twice traded breaks, before Kostyuk came up with a tight hold in the 11th game and raised her level at the end to claim the opening set with a backhand crosscourt winner. Kostyuk's Historic Win It was the first time that Kostyuk had taken a set off the third-seeded Pole after three straight-set defeats in their previous meetings, and she sensed a big upset when she went ahead 3-1 in the next set after a battling effort. The Impact on Swiatek's Title Hopes The Rouen and Madrid champion held her nerve from there to take her record on clay this season to 15-0, and book a meeting with the seventh-seeded Ukrainian Elina Svitolina or the 11th-seeded Swiss Belinda Bencic in the next round at Roland Garros.

The Schreiber family, presiding over a nationwide commercial portfolio via the Midos Group, is at the center of a growing controversy involving two distinct business models: aggressive tax avoidance and the profiteering from the UK's housing crisis. The Dual Nature of the Schreiber Business Empire The investigation reveals a complex web of family-owned entities that appear to operate on opposite ends of the social spectrum. On one side, the Midos Group is accused of exploiting a controversial tax scheme to avoid business rates on empty commercial properties. On the other, a similarly named but ostensibly separate entity, Midos Management Co, is profiting from the UK's chronic shortage of social housing by arranging temporary accommodation for homeless residents. Midos Group: Accused of using the 'faith room' scheme to avoid rates on empty units. Midos Management Co: Collecting fees for arranging temporary accommodation for councils. Key Figures: David Schreiber (Midos Group) and Elizabeth Endzweig (Midos Management Co). Financial Impact of the 'Faith Room' Tax Loophole The core of the tax avoidance allegations centers on a provision that exempts property owners from paying business rates if the space is made available for religious worship. The 'faith room' scheme, marketed by Verity, allegedly involves minimal activity—such as placing a notice and a staff member reading scripture—to create the appearance of worship. Total Savings: Landlords have saved at least £18m through this scheme. Specific Case: Dover District Council is suing for £1.7m of unpaid tax. Properties Involved: Discovery Park in Kent and a disused pub in Clapham, London. Profiting from the Homelessness Crisis While the family allegedly avoids taxes on empty buildings, they are simultaneously capitalizing on the housing emergency. Midos Management Co acts as an intermediary, matching councils with private landlords to house homeless residents. Despite claims of separation, evidence suggests significant overlap between the two entities. Revenue Collected: At least £43m collected on behalf of landlords since 2019. Client Base: Lambeth council and at least four other councils. Directorship Overlap: Elizabeth Endzweig, daughter of David Schreiber, is a co-director of multiple companies sharing the same address as Midos Group. The Future of UK Property Tax Compliance The revelations highlight a growing tension between private profit and public service obligations. With MPs and councils increasingly scrutinizing these arrangements, the 'faith room' exemption is likely to face tighter regulatory oversight. The case sets a precedent for how closely connected family businesses can be without violating anti-avoidance rules, potentially leading to stricter audits of corporate structures in the property sector.

The Incursion Israeli forces have entered Lebanon, crossing the Litani River, a significant geographical and political boundary in the region. This move marks a serious escalation in the ongoing tensions between Israel and Lebanon. Capture of the 12th Century Castle The Israeli forces have successfully seized a 12th century castle in Lebanon. The castle, a historical and cultural landmark, is now under Israeli control, adding a layer of complexity to the conflict. Regional Implications This incursion and capture have significant implications for the region. The Litani River crossing and the seizure of the castle could lead to increased military presence and potential conflict escalation. International Response The international community is likely to respond to this development, with potential condemnations and calls for de-escalation. The incident may lead to increased diplomatic efforts to resolve the conflict. Future Outlook The situation remains volatile, with potential for further escalation. The capture of the castle and the crossing of the Litani River may lead to a prolonged period of heightened tensions and military activity in the region.

The Concept of 'Mind Children' A few months ago, an AI researcher from Europe attended a dinner party in Silicon Valley. During one of the many courses, the host addressed his guests, all of whom worked in AI. The researcher paraphrased his message like this: “Isn’t it amazing that we are the last generation of humans who will need to think about procreating biologically? We were lucky enough to be born at a time where we can simply upload our consciousnesses instead.” The Book That Sparked the Conversation The book in question was Hans Moravec’s Mind Children: The Future of Robot and Human Intelligence, which was first published in 1988, and which at the time, according to economist and futurist Robin Hanson of George Mason University, caused a big splash in a small pond – the community of robotics and machine-learning experts to which Moravec belonged. The Data Analysis Moravec’s book is more philosophical treatise than technological manual, but the central idea is that cultural evolution has long since taken over from biological evolution as the most powerful force shaping humanity. The logical extrapolation of this is that the information that encodes our future selves would soon be packed into hardware and software rather than DNA. The Impact Analysis Angela Aristidou, who studies the real-life deployment of AI at University College London, is not surprised that Moravec’s book is enjoying a revival. She says that what in 1988 might have read like science fiction – and still might to most of us – looks eminently realisable to those in the know. The Prediction Hanson shares his conviction that the revolution is inevitable, as soon as AI attains something experts agree to call human-level intelligence. “We are going to generate an explosion of things like us in the future, who will be different from us in many ways,” Hanson says. “To the extent that they have minds somewhat like ours, they are our mind children.”

The Architecture of an African GiantIn less than two decades, Morocco has redefined African football, evolving from a team frequently eliminated in group stages to a global powerhouse ranked in the top 10 of the FIFA men’s rankings. This meteoric rise is not accidental but the result of a long-term national project initiated by King Mohammed VI in 2008.The success is built on three distinct pillars: good governance, financial investment, and competent human resources. The first step involved creating a national department for financial control to professionalise the federation's structure. This was followed by a massive infrastructure overhaul, including the construction of thousands of 'proximity fields' for mass participation and the Mohammed VI Complex in Maamoura, a technical center often compared to France's elite Clairefontaine academy.A Trophy Cabinet OverflowingThe impact of this strategy is evident in the sheer volume of recent accolades. The Atlas Lions have dominated across every age group, securing titles that span senior, youth, and women's football:2025 AFCON Champions (after Senegal were stripped of the title)2025 WAFCON Finalists2025 FIFA Arab Cup Champions2025 African Nations Championship (CHAN) Champions2025 U-20 FIFA World Cup Champions2025 U-17 AFCON Champions2024 Olympic Men’s Bronze Medallist2024 Futsal AFCON ChampionsThe Diaspora Strategy and Infrastructure BoomA critical factor in Morocco's ascent is the reform of national eligibility rules, which opened the door to players from the European diaspora. This strategy has attracted stars like Hakim Ziyech, Nordin Amrabat, and Brahim Diaz.The latest addition to this lineage is Ayyoub Bouaddi, an 18-year-old Lille midfielder. Despite interest from Zinedine Zidane and the French national team, Bouaddi chose to represent Morocco, highlighting the magnetic pull of the national project. The Mohammed VI Complex has already produced top talent, including Nayef Aguerd, Azzedine Ounahi, and Youssef En-Nesyri.Navigating the 2026 World Cup and the 2030 DreamWith high expectations for the 2026 World Cup in the USA, Canada, and Mexico, Morocco faces a transitional period following the resignation of coach Walid Regragui after the controversial 2025 AFCON final. The federation has appointed Mohamed Ouahbi, who led the youth team to the U-20 World Cup title.While Ouahbi’s more adventurous style differs from Regragui’s pragmatic resilience, the foundation is solid. The world views Morocco as a credible contender, but the team understands that the 2026 tournament is merely a milestone. With Morocco set to co-host the 2030 World Cup alongside Spain and Portugal, the current success is viewed as the acceleration of a broader national development agenda.

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.
