Science Alert reports that the critically endangered North Atlantic right whale has shown a modest population increase of 2% in 2024, with births rising to eight calves. The total population now stands at an estimated 384 whales. While this is a hopeful development, experts like Heather Pettis from the New England Aquarium stress the need for sustained conservation efforts, as threats such as vessel collisions and fishing gear entanglements continue to endanger the species. The situation highlights the delicate balance between human activity and marine conservation, emphasizing the necessity of stricter regulations, such as the adoption of ropeless fishing techniques and protected zones, to ensure long-term recovery.

A clinical trial described by Science Alert suggests that two existing medications—empagliflozin, a diabetes drug, and an insulin nasal spray—may help mitigate early symptoms of Alzheimer's disease. The trial, involving 47 participants, found that empagliflozin reduced brain injury markers while the insulin spray improved cognitive function and white matter connectivity. Although the trial was small and focused on safety, the findings highlight the potential of targeting metabolic pathways for Alzheimer’s treatment. Future larger trials could provide more definitive results, potentially altering the landscape of dementia care. This research underscores the importance of repurposing existing drugs to address complex diseases, a cost-effective and time-efficient approach in global healthcare. Source 21

A study published in npj Urban Sustainability and highlighted by Science Alert warns that rising sea levels could endanger millions of buildings in the Global South by the end of the century. Using high-resolution mapping, researchers estimate that 3 million buildings could be submerged with a 0.5-meter rise, while 130 million could face inundation under worst-case scenarios. The findings stress the urgency of addressing climate change, particularly in low-lying coastal areas where urban planning and mitigation strategies are critical. While international agreements aim to limit global warming, the report reinforces the need for accelerated action to safeguard vulnerable populations and critical infrastructure. Source 23

Science Alert details a groundbreaking study on venomous snake bites conducted at Venomworld, Paris, which used high-speed cameras to analyze strikes from 36 species. Researchers uncovered significant differences in bite strategies among vipers, elapids, and colubrids, shedding light on their evolutionary adaptations. For instance, vipers’ high-speed, precise strikes contrast with the slashing motions of colubrids. This study could have implications for antivenom development and public health initiatives in regions where snakebites remain a major issue. The findings also illustrate how evolution optimizes survival mechanisms in diverse ecological niches. Source 17

New dietary guidelines from the British Dietetic Association, as cited by Science Alert, suggest surprising alternatives for managing chronic constipation, recommending kiwifruit, mineral water, and magnesium supplements over traditional high-fiber diets. The emphasis on kiwifruit, which contains beneficial enzymes and fibers, challenges long-standing dietary norms. This shift underscores the importance of personalized nutrition based on scientific evidence, though potential accessibility issues for such recommendations could limit widespread adoption. The findings may prompt broader discussions on revising global dietary guidelines. Source 22

According to Al Jazeera, 25-year-old Mahnoor Omer has petitioned Pakistan’s Lahore High Court to remove taxes on sanitary products, arguing that these taxes exacerbate inequality and restrict access for women. With only 12% of women in Pakistan using commercially produced pads, the legal challenge underscores a broader struggle against economic and social stigmas surrounding menstruation. If successful, the case could improve school attendance and overall health outcomes for women, serving as a potential model for similar advocacy efforts in other countries with comparable challenges.

Further advancing the field of Alzheimer’s treatment, Science Alert reports on a small-scale study testing the combined effects of empagliflozin and insulin nasal spray. Although the primary goal was safety, the study observed cognitive improvements and reduced brain injury markers, offering potential avenues for early intervention in neurodegenerative diseases. This underscores the importance of exploring metabolic pathways for disease management, though larger trials are necessary to confirm efficacy. Source 21

The North Atlantic right whale population’s modest recovery, as reported by Science Alert, reflects incremental progress in marine conservation. However, challenges like entanglement in fishing gear persist, highlighting the need for stricter protective measures. This case illustrates how targeted conservation efforts can yield results but require sustained focus and adaptation to new threats. Source 16

Al Jazeera reports that EU leaders have delayed a decision on using frozen Russian assets to fund a €140 billion loan for Ukraine, citing legal and logistical concerns raised by Belgium. While Ukrainian President Volodymyr Zelenskyy has urged swift action, the proposal has faced resistance over fears of litigation and economic repercussions. The delay reflects broader geopolitical tensions within the EU over how to balance military and financial support for Ukraine with the risks of escalating conflict with Russia. This highlights the challenges in achieving unity among member states on high-stakes global issues. Source 27

The BBC highlights a troubling tripling of obsessive-compulsive disorder (OCD) cases among 16–24-year-olds in England over the past decade. This rise may reflect greater awareness and diagnostic capabilities but also indicates growing mental health pressures on young people. The report points to the urgent need for expanded mental health services in educational institutions to address this trend. Policymakers must balance investment in healthcare with preventive strategies, including social support and stress management programs, to combat the underlying causes of this concerning rise.
