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 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.

In April 2024, a local wildlife ranger recorded a pale horseshoe whip snake gliding through the turquoise waters between Ibiza and the tiny islet of Santa Eulària, providing the first indisputable visual proof that the invasive snake can swim and expand its range across the Balearics.The First Video Confirms Snakes Swimming Between Ibiza and Santa EulàriaThe footage, shot on a minuscule island 450 metres off Ibiza’s east coast, validates long‑standing anecdotal reports from fishermen and tourists. Biologist Oriol Lapiedra of the Centre for Ecological Research and Forestry Applications (Creaf) noted that while snake sightings were common, this was “the first proper evidence” of a snake making the crossing.Captures and Projections Reveal a Rapidly Expanding Snake PopulationMore than 3,500 horseshoe whip snakes were captured on Ibiza in 2025 alone.Since 2016, over 16,000 individuals have been culled.Scientists forecast that the species will occupy 100 % of the island by the end of 2027.On the mainland, snakes rarely exceed 1.8 m in length, but Ibiza specimens have been recorded at over 2 m and weighing 2.5 times as much.Ecological Fallout: Endangered Wall Lizards Face Near‑ExtinctionThe Ibiza wall lizard (Podarcis pityusensis) was upgraded by the IUCN in October 2022 from “near threatened” to “endangered”, reflecting the mounting pressure from the snake. On Santa Eulària, researchers counted 72 lizards in 2016 but only three in 2023. Across the ten islets that once hosted unique lizard populations, many have now lost their native reptiles entirely, erasing thousands of years of isolated evolution.Future Outlook: Management Strategies and the Likelihood of Island‑Wide InfestationRegional authorities, in partnership with Creaf and conservation NGOs, are intensifying capture programmes and exploring “Noah’s ark” captive‑breeding projects to preserve genetic stock. However, the sheer scale of the snake invasion—driven by imported olive trees that provide hidden refuges—means that without sustained effort, the horseshoe whip snake could dominate the Balearic archipelago, reshaping its ecosystems for decades to come.

Syrian National Commission for Missing Persons (NCMP) announced on 31 May 2026 that the children of dentist and former chess champion Rania al‑Abbasi are “likely deceased,” concluding a decade‑long search for the family who vanished in March 2013.NCMP Confirms Likely Death of Rania al‑Abbasi’s Children After Decade‑Long DisappearanceThe commission said its conclusion is based on “multiple verification and analysis procedures” carried out with national authorities. Hassan al‑Abbasi, the sister’s brother, posted a video confirming the deaths after viewing recordings linked to the 2013 Tadamon massacre, where the children were allegedly accused of financing terrorism.Scale of Forced Disappearances Under the Assad Regime300,000 people may have gone missing over decades of al‑Assad family rule, according to NCMP data.Tens of thousands were detained or disappeared during the civil war that began in 2011.The Tadamon massacre, tied to Amjad Youssef, resulted in at least 41 documented killings.These figures illustrate the breadth of the humanitarian crisis and the challenges facing investigators.Implications for Syria’s Transitional Justice and Reconciliation EffortsThe confirmation of the children’s deaths adds a personal dimension to the broader missing‑persons issue, which has become a symbol of the suffering endured by detainees’ families. It strengthens calls for transparent trials, such as the recent prosecution of former Assad‑era officials, and pressures the new government to deliver “just punishment” for perpetrators like Amjad Youssef.Future Outlook for Accountability and Missing Persons InvestigationsWhile the NCMP says efforts to locate remains are ongoing, the case sets a precedent for using video evidence and coordinated forensic analysis. International observers expect increased scrutiny of Syrian courts and potential cooperation with UN mechanisms to address the estimated 300,000 missing cases. Continued revelations may accelerate reforms in the country’s legal and investigative frameworks.

The Rise of Nigeria's Digital Herbal Marketplace In Abuja, Nigeria, Oke Bola thought a fertility supplement she found online might help her conceive. Instead, within days of taking it, she struggled to breathe. Her experience reflects a growing online trade in unverified herbal remedies promoted across social media platforms. Bola, who is in her early 40s and has never had children, bought the supplement earlier this year and increased the recommended dosage, hoping for quicker results after hearing about it from friends and family. "I recognised the symptoms of asthma; the wheezing sound at night was familiar," she told Al Jazeera. "When I checked online, I realised it could be from the herbal medication." Her experience is not isolated. Across Nigeria, doctors and pharmacists report a surge in social media-driven self-medication, particularly involving unverified herbal products. This trend is worsening health outcomes, delaying treatment, and adding pressure to an already strained healthcare system serving about 230 million people. Nigeria's young, hyperconnected population increasingly uses digital platforms for health information and advice. But that access has also created what Dr Isaac Kolawole and Dr Fidelis describe as an "algorithmic apothecary" – an unregulated online marketplace where influencers and anonymous sellers promote remedies directly to consumers with little or no scientific backing. Health Impacts of Unverified Herbal Remedies Within this ecosystem, herbal remedies, long part of Nigeria's medical and cultural landscape, are increasingly repackaged as miracle cures, sometimes with dangerous consequences. Doctors report more patients arriving at hospitals only when their conditions have significantly worsened, often after prolonged use of unverified treatments. A consultant nephrologist at the University College Hospital in Ibadan, Dr Yemi Raji, said herbal medicine continues to play a role in kidney disease cases in Nigeria. "When you take herbal medication, you are taking both the good and the bad," he said. "Patients often arrive late, when treatment is more difficult and expensive." Dialysis alone can cost between 50,000 and 100,000 naira ($36-72) per session, several times a week. Studies link herbal use to kidney and liver disease cases across Africa, including findings that about 46 percent of liver disease admissions in one Nigerian hospital involved herbs or roots. A 2022 study found that 76.65 percent of participants had used herbal medicine, with more than a third combining herbal and conventional treatments while 82.44 percent did not inform their doctors. The Algorithmic Amplification Effect On a smartphone screen, relief is just a click away: fertility tonics, eye drops promising restored vision, syrups claiming to "flush out" disease. The advertisements are polished, persuasive and constant, woven into TikTok, Facebook, Instagram and X feeds. "The platforms themselves amplify this effect," said Dr Egemba Chinonso Fidelis, a public health advocate known online as Aproko Doctor. "Their algorithms reward engaging content and push it to wider audiences." Even users who try to avoid such content often encounter it repeatedly, shaped by emotional storytelling, music and urgency-driven messaging. A 2025 Nigeria-based study on Jinja Herbal Mixture found it appeared safe for short-term use within tested dosage ranges, but researchers recorded biochemical changes at higher doses, including altered creatinine and sodium levels in test subjects, signs of possible kidney and liver stress. The study called for further research into long-term effects and interactions with conventional medicines. Regulatory Challenges in the Digital Age The National Agency for Food and Drug Administration and Control (NAFDAC) says it is working to track unregistered manufacturers, but enforcement remains difficult, especially online. "With the sheer volume of products online, enforcement has limited reach," said Isaac Kolawole, the southwest zonal director of NAFDAC. Many sellers use fake or incomplete addresses, making them difficult to trace. NAFDAC requires strict registration, testing and approval before herbal products can be sold or advertised, but regulation has not kept pace with online commerce. Fidelis argued that stronger regulation alone is not enough. "If there are no consequences for lying about healthcare online, people will keep doing it," he said. He noted that scammers have even used AI-generated versions of his image to promote fake products. "Real medicine does not promise to cure everything, and it does not rely on countdowns," he added. "Scammers do." Path Forward for Safer Digital Health As Nigeria's digital economy expands, the intersection of technology and healthcare will only grow more complex. Fidelis stressed that access to affordable healthcare must improve, public trust must be rebuilt, and digital platforms must take responsibility for the health content they amplify. Pharmacist Akinade Akinlolu noted that while conditions like diabetes and hypertension can be managed, online claims often suggest cures. "Economic pressure is also pushing people towards cheaper or 'miracle' alternatives," he added. "Without stronger safeguards," Fidelis warned, "the algorithmic apothecary will continue to grow and put more people at risk." The challenge for Nigeria's healthcare system is to harness the power of digital platforms while ensuring they promote evidence-based care rather than potentially harmful alternatives.

The LeadMost men in the UK will not be offered prostate cancer screening if the government accepts the final recommendation of an expert committee. The UK National Screening Committee (UKNSC) has concluded that widespread screening using the prostate-specific antigen (PSA) test was "likely to cause more harm than good" despite prostate cancer being the most common cancer in the UK.The Recommendation DetailsThe committee recommended screening only for men with the BRCA2 gene variant who have a family history of certain cancers, suggesting they be screened every two years between the ages of 45 and 61. For this specific group, prostate cancer is more common, develops earlier, and can be more aggressive. Of 100 men with a BRCA2 variant, between 21 and 35 will develop prostate cancer before the age of 80.The committee recommended against screening for other at-risk groups, including black men, citing "ongoing uncertainty on whether screening would cause more good than harm." The main harms of population screening include incontinence and erectile dysfunction in men who do not need treatment for the disease.The Prevalence DataProstate cancer is the most common cancer in the UK, with more than 64,000 men diagnosed every year. However, there is currently no national screening programme for the disease. The UKNSC estimates that its final recommendation would lead to "a few thousand" men being screened for prostate cancer each year.Only around one in every 300 to 400 people will have BRCA gene variations, though as many as one in every 40 Ashkenazi Jewish people carry these variations. In England, the NHS offers free BRCA gene testing for anyone aged 18 or over who has at least one Jewish grandparent.The Impact AnalysisThe decision will come as a blow to campaigners who have voiced support for more widespread screening, including high-profile figures like Sir Chris Hoy, David Cameron, and Sir Stephen Fry. Prostate Cancer UK expressed being "deeply disappointed" with the recommendation, stating that without a screening programme for the UK's most common cancer, "we lose more than 12,000 dads, brothers and partners every single year."However, medical experts argue that screening can reduce deaths from prostate cancer only to a small extent and does not improve overall survival. The challenge remains that once a prostate cancer is found, doctors still can't reliably tell which cancers need treatment and which do not, and treatments can cause long-lasting harm.The Future OutlookThe government will now consider the recommendation, with the new Health Secretary James Murray set to meet with the UKNSC chair. The Department of Health and Social Care stated that Murray "will give full and careful consideration to the recommendation" and would update on the government's response shortly.The committee acknowledged that more research is needed to address evidence gaps, particularly regarding black men. The UKNSC will work with the Transform trial, launched by Prostate Cancer UK, to gather more data. It was noted as "particularly important" that a "sufficient number" of black men be invited to participate in this trial.

Outcry Over Shnaider’s Gazprom‑Backed AppearanceDuring a post‑match press conference after losing 7‑5, 6‑1 to a Russian opponent at the French Open, Oleksandra Oliynykova called for sanctions against fellow competitor Diana Shnaider. Oliynykova said Shnaider’s participation in a Gazprom‑sponsored exhibition in St Petersburg directly supports the Russian war effort in Ukraine. Oliynykova’s Accusations and EvidenceOliynykova presented journalists with photographs of Shnaider playing at the “Northern Palmyra Trophies” exhibition, an event funded by state‑owned oil giant Gazprom. She also shared screenshots suggesting Shnaider had “liked” pro‑Vladimir Putin posts on Instagram, linking the athlete to propaganda supporting the invasion. Absence of Financial Penalties and Sponsorship FiguresNo monetary fine or official sanction has yet been imposed on Shnaider for the exhibition.The article does not disclose the exact amount Gazprom contributed to the event, only that it was a corporate sponsor.Current tennis governing bodies have not publicly addressed the conflict between sponsorship and war‑related funding. Potential Ripple Effects on Tennis Governance and SponsorshipThe demand highlights a broader tension: athletes competing in events backed by entities linked to conflict may face moral scrutiny, while governing bodies claim limited enforcement mechanisms. If sanctions were applied, they could set a precedent for future vetting of tournament sponsors, especially in geopolitically sensitive regions. Future of Sanctions and Athlete ActivismOliynykova’s outspoken stance positions her as a leading Ukrainian voice on the war, suggesting that more players may use their platforms to pressure governing bodies. Should the International Tennis Federation or national federations act, we could see stricter sponsor vetting, possible bans on events tied to sanctioned companies, and a shift toward greater athlete‑led advocacy in sport politics.

Rising rates of youth unemployment have created a split at the top of government over how fast it should meet its promise to give young people the full minimum wage.The Manifesto Promise vs. The Reality CheckPeter Kyle, the business secretary, is understood to believe now is not the time to give 18- to 20-year-olds the full minimum wage, which Labour promised to do in its manifesto. Others believe there is little evidence to show that recent pay rises for low-paid workers have had any effect on unemployment.Torsten Bell, a Treasury minister, told the BBC on Friday morning: “If you look at what the Low Pay Commission said in their annual report, they didn’t find evidence that previous increases in the minimum wage for young people had had an effect on their employment.”The £125bn Cost of InactionThe splits have emerged following a landmark government-backed report this week by the former Labour minister Alan Milburn, who found that youth unemployment was costing Britain more than £125bn a year. Milburn’s report revealed the number of young people not working or studying had surpassed a million for the first time in more than a decade, prompting calls to reduce the pace of youth minimum wage increases.Current Youth Rate: £10.85 (up 8.5% this year)Main Minimum Wage: £12.71 (up 4.1% this year)NEETs (Not in Education, Employment, or Training): Over 1 millionThe Hospitality Sector DilemmaMilburn himself told the News Agents podcast this week: “To get the jobs there for them, you’ve got to make sure the employers are willing to take the risk. If you’re in, say, the hospitality sector or the retail sector, margins tend to be very low. These tend to be sectors that were really badly hit by the cost of living, hospitality in particular.”Tony Blair, the former prime minister, warned in an essay this week that policies such as increasing the minimum wage – which he brought in – had created “headwinds, not tailwinds, for businesses.”The October Low Pay Commission VerdictLabour promised in its manifesto to equalise the rates of the minimum wage for 18- to 20-year-olds with those of workers who are 21 and over but did not say how quickly this would be achieved. Bell said on Friday: “We’re committed to our manifesto that we stood on and we will deliver it. But that manifesto did not set out the timeline.”While he and others in the government believe they should slow down the pace of rises in youth rates of the national minimum wage if there is evidence that it has an impact on employment, they do not yet believe that evidence exists.The commission will tell the government in October what it is recommending for the financial year starting on 1 April 2027; some in government privately hope it will give a recommendation significantly lower than this year’s. Earlier this year ministers even changed their guidance to the LPC to reflect the concerns in government over unemployment among young people, telling it to prioritise employment rates instead.

Lead: Federal authorities arrested ICE agent Christian Castro in Texas after Minnesota investigators linked him to the non‑fatal shooting of Venezuelan immigrant Julio Cesar Sosa‑Celis during the controversial Operation Metro Surge raid on January 14, 2026. Arrest of ICE Agent Christian Castro in Texas Castro, 52, was taken into custody on May 24, 2026 with assistance from the Texas Rangers and the Department of Homeland Security’s inspector‑general office. The arrest followed a multi‑state manhunt after Minnesota officials identified him as the shooter who fired through a front door, striking Sosa‑Celis in the leg. Legal Charges and Potential Penalties Four counts of second‑degree assault One count of falsely reporting a crime Each assault count carries a potential sentence of up to 10 years in prison, while the false‑report charge could add another 5 years. The case marks only the second instance this year of a federal officer being charged for actions taken during Operation Metro Surge. Broader Implications for Operation Metro Surge The incident has amplified criticism of the December 2025‑January 2026 immigration sweep, which deployed hundreds of agents across the Minneapolis‑St. Paul area. Prior allegations that Sosa‑Celis and a housemate assaulted ICE officers were later disproven by video evidence, leading to dropped charges against the immigrants and prompting DHS to acknowledge false statements by its officers. State officials, including Minnesota Attorney General Keith Ellison, emphasized that “nobody is above the law,” underscoring growing demands for accountability within federal immigration enforcement. What This Means for Future Immigration Enforcement Legal experts predict that Castro’s prosecution could set a precedent for holding ICE personnel criminally liable for misconduct, potentially curbing aggressive tactics in future operations. Congressional oversight committees are expected to request additional hearings on Operation Metro Surge, and the DHS may face pressure to revise its use‑of‑force policies. Should the case proceed to conviction, it could trigger broader reforms, including stricter reporting requirements, enhanced body‑camera usage, and increased coordination with state and local law‑enforcement agencies to ensure compliance with constitutional standards.
