Kano’s bustling Sabon Gari Market has turned into a frontline for Nigeria’s growing e‑waste dilemma. Residents like Marian Shammah, a 34‑year‑old cleaner, purchase second‑hand refrigerators for as little as 50,000 naira (≈ $36), only to see them fail within weeks, forcing them back to the market for another replacement. For many Nigerians, imported used appliances are perceived as more durable than locally produced models, despite the fact that a substantial portion arrives already defective. UN data indicate that roughly 60,000 tonnes of used electronics reach Nigeria each year, with at least 15,700 tonnes damaged on arrival. A 2015‑2016 UN tracking study found that over 85 % of these imports originated from Germany, the UK, Belgium, the Netherlands, Spain, China, the United States and Ireland. These shipments frequently breach the Basel Convention, the international treaty that restricts the export of hazardous e‑waste to countries with weaker environmental safeguards. Yet, exporters exploit loopholes—labeling cargo as “personal effects” or “for repair”—to evade thorough inspections. Health experts warn that the fallout is severe. E‑waste contains substances such as mercury, lead, and banned refrigerants (R‑12, R‑22) that persist in the environment for decades. Informal recyclers in Kano dismantle appliances without protective gear, inhaling toxic fumes and handling heavy metals, which leads to chronic respiratory problems, skin irritation, and even reproductive issues. A recent study by the International Journal of Environmental Research and Public Health linked these symptoms to long‑term toxic exposure among workers and nearby residents. Local medical professionals echo these concerns. Dr. Ushakuma Michael Anenga of the Benue State Teaching Hospital highlighted that heavy‑metal contamination and refrigerant gases jeopardize both respiratory and renal health, especially for children and pregnant women. Economically, the trade offers a false bargain. While a second‑hand fridge may cost half the price of a new unit, failures within months impose hidden costs—spoiled food, repeated purchases, and lost income for small business owners. Vendors such as Umar Hussaini admit that many items are sold “as is,” without warranties or functional testing, and that a significant share of imports arrive with faults. Nigeria’s regulatory body, the National Environmental Standards and Regulations Enforcement Agency (NESREA), asserts that imports are permitted only when they meet strict functionality criteria. In practice, however, traders often declare goods as household items to bypass scrutiny, and enforcement remains uneven. Industry observers argue that the profit margins for exporters and local brokers—who capitalize on the price differential between costly recycling in Europe and high demand for affordable “tokunbo” goods in Nigeria—are driving the continued influx. Ibrahim Adamu of the NGO Ecobarter calls for reinforced border inspections and extended producer responsibility schemes to shift the financial burden of safe disposal back onto manufacturers. With estimates that up to three‑quarters of imported electronics may be essentially junk, the situation underscores a broader systemic issue: wealthy nations offload hazardous waste while developing economies bear the environmental and health consequences. Until comprehensive enforcement and international accountability mechanisms are established, Nigerian consumers like Shammah will remain caught between the need for affordable appliances and the risk of repeated loss.

For the first time, scientists have documented whales assisting each other during birth, a behavior previously only observed in primates. A team from Project Ceti, an international effort to understand whale communication, captured the extraordinary footage off the coast of Dominica in the Caribbean on July 8, 2023.The team observed a pod of 11 whales, including a 19-year-old female named Rounder, who was about to give birth to her second calf. Over nearly five and a half hours, the scientists documented the group's behavior, filming them with drones and recording sounds underwater. This exceptional rarity in the history of science was published in the journals Scientific Reports and Science.Out of 93 species of cetaceans, only nine have been observed giving birth in the wild. What's even rarer is that unrelated whales were helping the mother. The birth lasted 34 minutes, during which other adult females dived under Rounder's dorsal fin, often on their backs with their heads facing her genital slit.Immediately after birth, the pod's behavior changed rapidly, with all adults touching and squeezing the newborn's body with their heads, pushing it around underwater and on their bodies above the surface. This behavior is believed to help the newborn calf, which sinks after birth, prevent drowning and facilitate its first breaths.The scientists also recorded significant changes in vocalization during the birth, suggesting that the group was coordinating to support the birth or protect the newborn. Sperm whales have one of the longest pregnancies in the animal kingdom, with a gestation period of up to 16 months, and calves rely on their mother's milk for at least two years.The newborn was spotted again on July 25, 2024, with other young members of the pod, indicating that it had survived its first year, a good sign of reaching adulthood.

Saudi Arabia has urged the US to ramp up attacks on Iran, a Saudi intelligence source has confirmed, while it is weighing a decision on whether to join the fight directly. The Saudi source confirmed reporting that the kingdom’s de facto leader, Crown Prince Mohammed bin Salman, has urged Donald Trump not to cut short his war against Iran, and that the US-Israeli campaign represented a “historic opportunity” to remake the Middle East.The intelligence source said Riyadh was not just calling for the military campaign to be continued, but to be intensified. Trump appeared to confirm the report about the crown prince’s role, telling journalists on Tuesday: “Yeah, he’s a warrior. He’s fighting with us.”There are no reports of active Saudi military involvement in the nearly four-week-old war so far, but a Saudi political analyst said the kingdom was likely to take that step if current peace efforts led by Pakistan failed.“What matters now is Iran’s decision,” Mohammed Alhamed, a Saudi geopolitical analyst, said. “If Iran engages seriously, there is still a path to contain escalation. If it rejects the conditions and continues its attacks, the threshold for Saudi action will be crossed.”Alhamed added that Saudi Arabia “is not reacting impulsively”.“It is calibrating its response and preparing for a scenario where escalation, if it happens, will be deliberate and decisive,” he said, adding that Saudi Arabia “has not been pushing for war.”“It has been trying to avoid being drawn into it, while keeping all options on the table,” he said.Saudi Arabia has come under Iranian drone attack, as part of Tehran’s response to the US-Israeli attack on 28 February. One drone strike a week ago hit an oil refinery in Yanbu on Saudi Red Sea coast.The attack on Yanbu signalled an Iranian warning that it could also threaten that economic lifeline.“I believe that Saudi Arabia still maintains cautious neutrality in the Iran-Israel-US war,” Hesham Alghannam, a Saudi defence expert told Agence France-Presse. But he added: “If the Houthis strike Saudi assets, Riyadh may shift toward defensive coalition support or limited retaliation.”The crown prince solidified his hold on power by cultivating a close relationship with Trump, but will now have to rethink Saudi reliance on the US for its security, observers have argued.“MBS [Mohammed bin Salman] has lost the bet on all his investments over the last several years,” Ellie Geranmayeh, senior policy fellow at the European Council on Foreign Relations said. “He financially invested in Trump and Trump’s family and his corporation and his White House, but at the end of the day the views of the Saudis and of the whole Gulf have been sidelined by the wishes of Benjamin Netanyahu.”

Renowned Formula One journalist Giles Richards was ejected from a Max Verstappen press conference at the Japanese Grand Prix, a rare occurrence in the sport. The incident stemmed from a question Richards asked Verstappen at the end of last season regarding an incident involving Verstappen and George Russell at the Spanish Grand Prix.Verstappen had collided with Russell's car during the Spanish Grand Prix, resulting in a 10-second penalty that dropped him from fifth to 10th place and cost him nine points. When Richards asked Verstappen about the incident during the season finale in Abu Dhabi, Verstappen took umbrage, suggesting Richards was biased and only focused on negative aspects of his performance.Richards recounts that when he encountered Verstappen at the Japanese Grand Prix, the Dutch driver refused to speak until Richards left the press conference. Despite attempts to clarify the situation, Verstappen remained resolute, telling Richards to 'get out'.The incident has sparked a heated debate about driver-journalist interactions in Formula One, with many colleagues expressing shock and concern for Richards' wellbeing. While Richards admits to feeling uncomfortable about being the story, he emphasizes the importance of asking difficult questions in his line of work.Richards has covered Formula One for over a decade and has interviewed Verstappen on multiple occasions, describing their interactions as generally friendly and good-humored. He hopes that he and Verstappen can have a better relationship in the future.

A recent study conducted by researchers at Adelaide University has revealed that sperm in microgravity environments become disoriented and struggle to navigate through a simulated female reproductive tract. This finding has significant implications for the future of human reproduction in space, particularly as plans for lunar and Mars settlements gain momentum. The researchers used a machine to mimic microgravity, similar to the conditions experienced by astronauts on the International Space Station. They found that sperm tumble around like untethered astronauts, unable to determine their direction. This disorientation resulted in a 40% reduction in the number of microgravity-exposed human sperm that successfully navigated the maze compared to the control group. The study, published in the journal Communications Biology, highlights the challenges of reproduction in space. Dr. Nicole McPherson, the lead researcher, noted that understanding the effects of microgravity on sperm navigation is crucial for the success of future space missions. The study also found that adding progesterone helped overcome the sperm's disorientation, suggesting a potential solution for improving fertility in space. The research has broader implications for both space exploration and earthly reproductive science. As NASA's Artemis mission and private companies like SpaceX plan for human habitats on the moon and Mars, understanding the effects of microgravity on reproduction becomes increasingly important. The study's findings also contribute to the ongoing discussion about the feasibility of human settlements on Mars and the need for sustainable reproductive technologies. The Adelaide researchers collaborated with the university's Andy Thomas Centre for Space Resources to conduct the study. Their work builds on a history of research into reproduction in space, including NASA's 2018 mission to study the effects of weightlessness on human sperm. As space exploration advances, the need for further research into reproductive health in space becomes increasingly urgent.

Tracy Kidder, an award-winning narrative nonfiction writer, has passed away at the age of 80. Kidder was known for his ability to transform unlikely subjects into bestsellers, captivating readers with his in-depth research and storytelling skills. Throughout his career, Kidder immersed himself in various worlds, producing richly researched books on topics that may not have seemed like light reading. His work included The Soul of a New Machine, which explored the inner workings of a fledgling computer company in Silicon Valley and earned him the Pulitzer Prize and National Book Award in 1981. Kidder's other notable works include Among Schoolchildren, which highlighted the dedication of an inner-city teacher in Holyoke, Massachusetts, and Old Friends, which chronicled the lives of two friends in a nursing home. His book Mountains Beyond Mountains, about a doctor's efforts to bring healthcare to Haiti, introduced his work to a new generation of readers and inspired numerous universities to add it to their reading lists. Kidder's approach to storytelling was rooted in his belief that small things can have a significant impact. He avoided focusing on his personal interests, such as fishing or baseball, to maintain his objectivity and enthusiasm for his subjects. Kidder saw himself as a storyteller, not a 'literary journalist' or 'creative nonfiction' writer, and believed that nonfiction should not be limited by traditional techniques. Born in New York City in 1945, Kidder attended Harvard University and served in Vietnam, where he documented his experiences in My Detachment, a memoir that offered insights into the lives of support troops.

The relationship between dogs and humans has long been a subject of fascination, and recent groundbreaking research has shed new light on the origins of this enduring bond. Published in the journal Nature, the study reveals that the genetic evidence for domestic dogs dates back an astonishing 15,000 years, a full 5,000 years earlier than previously thought.Ancient DNA analysis of dog remains has provided unprecedented insight into the early days of dog domestication. The oldest specimen, a 15,800-year-old dog buried alongside human remains in Anatolia, Turkey, and a 14,300-year-old jawbone from Gough's Cave in Somerset, England, are key findings that have helped researchers reevaluate the timeline of dog domestication.According to Dr. Lachie Scarsbrook of Ludwig Maximilian University of Munich, the study suggests that dogs with diverse ancestries already existed across Eurasia 15,000 years ago, from Somerset to Siberia. This raises the possibility that domestication occurred during the last ice age, more than 10,000 years before the emergence of other domestic plants and animals.The research, conducted by international teams, analyzed DNA from bones at various sites, including Gough's Cave, Pınarbaşı in Turkey, and two sites in Serbia. Advanced sequencing techniques allowed researchers to piece together tiny fragments of ancient DNA, enabling clear species identification for the first time.Key findings include:Dogs were widespread across Europe and western Asia by at least 14,000 years ago.Isotopic analysis revealed dogs consumed a diet rich in fish, matching the local human diet in Turkey.Evidence of deep emotional bonds between humans and dogs, including the burial of puppies over human remains.The study's authors suggest that dogs may have increased hunting efficiency or served as an early warning system against predators. The genetic relationship between dogs across sites implies that they may have spread rapidly across Europe, possibly through trade between unrelated groups.As Prof. Laurent Frantz notes, the fact that people exchanged dogs so early suggests these animals must have been important, serving purposes beyond being pets. The research provides a fascinating glimpse into the ancient partnership between humans and dogs, highlighting the significance of this bond in human history.

A recent study published in the European Journal of Preventive Cardiology has revealed that small changes to daily habits can have a significant impact on cardiovascular health. The research, conducted by experts from Australia, Chile, and Brazil, examined data on more than 53,000 middle-aged UK adults taking part in the Biobank study.The study found that sleeping for 11 minutes more each night, doing 4.5 additional minutes of brisk walking, and eating an extra 50g of vegetables each day can reduce the risk of major cardiovascular events, including heart attacks and strokes, by about 10%. These small behavior changes were found to be more "achievable and sustainable" compared to attempting major changes in a single behavior.According to the study, the "optimal" way to avoid cardiovascular incidents includes getting eight to nine hours of sleep each night, a good diet, and a minimum of 42 minutes of moderate-to-vigorous physical activity each day. Combining these measures leads to a 57% lower risk of heart attacks and strokes.Dr. Nicholas Koemel, the study's lead author, noted that "making a few small, combined changes is likely more achievable and sustainable for most people when compared with attempting major changes in a single behavior." He encouraged people to make small changes to their daily routine, as they can have a surprisingly large positive impact on cardiovascular health.Prof Emmanuel Stamatakis, a senior author of the study, plans to build on these findings to develop new digital tools that support people in making positive lifestyle changes and establishing sustained healthy habits.Commenting on the study, Emily McGrath, a senior cardiac nurse at the British Heart Foundation, said that "small tweaks – like getting a little more sleep, adding a few extra minutes of activity to your day or eating a bit more veg – can work together to have a meaningful positive impact on your heart health."
