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.

The Landmark Broadcasting Deal CBS Sports has secured a four-year deal to broadcast the Women’s Super League (WSL) live in the US, starting from the next season and running until the end of the 2029-30 campaign. This deal represents a significant increase in valuation, potentially bringing in a fourfold increase in revenue for the WSL compared to previous seasons. Broadcasting Details Under the new agreement, the Paramount+ streaming service will air 183 WSL matches per season. Additionally, the CBS Sports Network will show one live match per week, with select matches also airing on the CBS Sports Golazo Network. This deal was negotiated by IMG, the international media rights representative for WSL Football. The Impact on Women's Football This deal marks a new record high for a US broadcasting agreement in the WSL. CBS Sports already holds rights to other women’s leagues, including the NWSL and the Women’s Champions League. The network had previously held WSL rights during the 2023-24 season. Zarah Al-Kudcy, WSL Football’s chief revenue officer, expressed excitement about welcoming CBS Sports back, highlighting their commitment to women’s football and their extensive talent roster. The Future of WSL Broadcasting The deal was finalized much earlier than previous agreements, which were typically announced shortly before the start of the season. This early conclusion brings stability and excitement ahead of the next WSL season in September. The partnership also comes as several WSL players have been named to the US women’s national team roster, further boosting the league’s profile.

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 Election Outcome Malta’s Labour Party (PL) has won an unprecedented fourth term in a victory for Prime Minister Robert Abela, according to preliminary results of the election held on Saturday. The party secured a comfortable parliamentary majority, although it appeared to be narrower than in 2022, when it took 55 percent of all ballots cast. Abela's Victory Speech “This is a victory of all the people based on the programme we presented for all the people,” Abela told reporters, saying results showed his party had “won a strong mandate”. He called for national unity, stating, “Let us maintain the spirit of national unity and move the country forward together.” Election Details Election held on Saturday with a turnout of 87.4 percent, slightly up from the last general election in 2022. Abela, 48, called the snap election a year early to shield Malta from geopolitical crises. The economy grew 4 percent last year, but there are concerns about the impact of the Middle East conflict on tourism and inflation. Opposition's Response Charles Bonello, general secretary of the opposition Nationalist Party (PN), conceded the election but noted that his party had managed to slash back Labour’s majority. The Road Ahead Abela has led Malta since 2020. His government will continue to focus on economic stability and addressing challenges such as corruption, which remains a significant issue in the country.

Uncovering Family History Through Fiction Maggie O'Farrell's journey into her family's past began with a childhood myth about an ancestor who worked on the first maps of Ireland. Years later, a hand-drawn map and an old photograph led her to discover the truth about her great-great-grandfather's role in the Ordnance Survey. The Mapper's Story O'Farrell's ancestor was a labourer and translator who worked on mapping divisions in Ireland during the aftermath of the great famine. His task was to ensure that the changes caused by the disaster were marked on the new post-famine versions of Ireland's maps. A Window into the Past The photograph showed O'Farrell's great-great-grandfather with a child on his knee, wearing a worn jacket and a low-brimmed hat. A hand-drawn map, beautifully rendered in coloured inks, revealed a tiny medallion with a red-jacketed soldier and O'Farrell's ancestor. The discovery sparked O'Farrell's curiosity about her family's history and the history of Ireland. The Impact of the Great Famine The great famine, which occurred between 1846 and 1852, had a devastating impact on Ireland, with over a million people dying of starvation or famine-related disease, and another million forced to emigrate. Fiction as a Tool for Discovery O'Farrell believes that fiction comes from what you don't know, and her book 'Land' is a testament to this. The novel tells the story of a man, Tomás, and his family, striving to emerge from the long shadow of the great famine. A New Perspective O'Farrell's book offers a new perspective on the history of Ireland and the impact of the great famine on families. Her research and writing have shed light on a little-known aspect of her family's history and the history of Ireland.

Sky announced it will exit its 24‑hour Arabic news joint venture with the United Arab Emirates, Sky News Arabia, following intense criticism over the channel’s coverage of the Sudan war and accusations of genocide denial. Under a new commercial agreement, Sky will give up all strategic and operational control but will continue to license the Sky News brand to the outlet. Strategic Withdrawal and New Licensing Arrangement The exit sees Sky handing over full ownership to IMI, the investment vehicle controlled by Sheikh Mansour bin Zayed al‑Nahyan, UAE vice‑president and Manchester City owner. In a statement, David Rhodes, executive chairman of Sky News Group, said the partnership had built a significant regional presence and that the timing was right for a change. IMI will now steer the platform’s future, while Sky secures a multi‑year brand‑licensing deal that lets the channel retain the Sky News Arabia name. Timeline of Sky News Arabia’s Decade‑Long Presence 2010: Channel launched in Abu Dhabi as a rival to Al‑Jazeera and BBC Arabic. 2012: Joint venture began broadcasting across the Middle East and North Africa. November 2025: Sudanese government banned the channel after a report claimed stability in El Fasher. February 2026: UN fact‑finding mission identified “hallmarks of genocide” in the RSF siege of El Fasher. May 2026: Sky announces exit and new licensing deal. Reputational and Regional Implications of the Sudan Coverage Controversy Internal Sky executives grew uneasy about the editorial line taken by Sky News Arabia, which was accused of whitewashing atrocities committed by the UAE‑backed Rapid Support Forces (RSF). Specific concerns included a report that downplayed the humanitarian crisis and the fact that the channel’s reporter in El Fasher was married to a senior RSF official. The controversy prompted Sudan to ban the channel and heightened scrutiny of the venture’s credibility across the Arab world. Future Outlook for Sky’s Middle‑East Footprint Nakhle ElHage, chief transformation officer at IMI, said the next phase will focus on building the platform into the leading multi‑media news destination for the Arab world. For Sky, the move mirrors a similar decision in Australia, where a licensing agreement for the Sky News brand is ending and the channel will rebrand as News24. The brand‑licensing arrangement allows Sky to maintain a presence without direct editorial responsibility, while IMI gains full control to shape content and investment strategy.

The Escalating Drone CampaignUkrainian drones have struck energy and industrial targets across several Russian regions, Russian authorities say, in an escalating campaign of strikes against infrastructure. In Saratov, a region on the Volga River with several oil refineries that has come under regular Ukrainian attack in recent years, Governor Roman Busargin said on Sunday on Telegram that "civil infrastructure" had been damaged in the overnight strikes.Strategic Targeting of Energy InfrastructureUkraine's military confirmed that it had struck the Saratov oil refinery overnight, but denied Russian accusations that it had hit the Zaporizhzhia nuclear power plant in Russian-occupied territory. In the Kirov region, northeast of Moscow and about 1,300km (800 miles) from Ukraine, Governor Alexander Sokolov said drones had hit a facility in the Urzhumsky district. The Ukrainian army confirmed the attack, saying it had also hit the Lazarevo oil-pumping station in the region.Regional Impact and Civilian CasualtiesGovernors in the Rostov, Voronezh and Belgorod regions, all of which border Ukraine, also reported strikes, and three civilians were injured in Belgorod. On Ukraine's Russian-controlled Crimean Peninsula, Moscow-backed Governor Sergei Aksyonov said authorities were introducing restrictions on sales of petrol, though he did not specify the reason. Ukraine for months has been attacking fuel infrastructure in southwestern Russia close to Crimea.International Support and Future StrategySeparately on Sunday, President Volodymyr Zelenskyy said Ukraine received a new Iris-T air defence missile launcher from Germany as he asked for the provision of more air defence ammunition from Kyiv's allies. "We also need missiles for air defence systems to have sufficient capabilities to repel Russian attacks," Zelenskyy said on Telegram.
