12-YEAR OLD RECEIVES HISTORIC GENE THERAPY FOR SICKLE CELL

Kendric Cromer, 12, became the first patient to receive FDA-approved gene therapy for sickle cell disease, leaving Children’s National Hospital in a wheelchair after a challenging 44-day stay. Wearing a “Naruto” T-shirt and cap, he expressed disbelief at the possibility of being free from the disease that had limited his childhood activities. Despite the celebratory mood, Kendric and his parents faced intense hardships during treatment, including chemotherapy that caused severe pain and complications. The gene therapy, costing up to $3.1 million, offers hope to many of the 100,000 Americans with sickle cell disease. While Kendric’s insurer approved the treatment, the physical and emotional toll was significant. Other patients have shared similar experiences, but many, like Kendric, are starting to feel better and embracing a future without sickle cell’s constraints. As Kendric begins to recover, he is learning to navigate life as a healthy teenager, hopeful for brighter days ahead. (New York Times)

CORAL REEF STUDY SHOWS FISH BIOMASS INCREASE POSSIBILITIES

As nations aim to protect 30% of the planet by 2030 (“30 × 30”), understanding the effectiveness of current conservation efforts is essential. A study analyzing approximately 2,600 global coral reef sites found that management strategies, including fishing restrictions, have resulted in about 10% of existing fish biomass on coral reefs. Furthermore, if fishing restrictions were extended to all unmanaged reefs, fish biomass could increase by an additional 10.5%. While the area of ocean protected is often seen as a metric of conservation success, outcomes vary significantly based on local conditions, complicating global assessments. This research develops a predictive model that quantifies the impact of protection efforts on fish biomass, indicating that without these initiatives, coral reefs would contain roughly 10% less fish biomass. Therefore, current protection measures account for approximately 10 kg of fish biomass for every 100 kg present on coral reefs today. (PNAS)

REMOTE TRIAL SHOWS PROMISING RESULTS FOR HOME DEPRESSION TREATMENT

A remote clinical trial involving over 150 participants has demonstrated the effectiveness of an experimental treatment for depression, using a swimming-cap-like device for transcranial direct current stimulation (tDCS) at home. This non-invasive therapy delivers a painless electrical current to the scalp, targeting the dorsolateral prefrontal cortex, a brain region linked to mood regulation. The study, published in *Nature Medicine*, revealed that after ten weeks, participants receiving tDCS experienced a greater reduction in depressive symptoms compared to a control group. Nearly 45% of those using the tDCS device reported significant improvement, contrasted with about 22% in the control group. While previous research has yielded mixed results, this trial’s home-based approach highlights the potential for accessible mental health treatments. Experts emphasize the need for further studies to personalize tDCS and understand its varying effects among individuals, potentially leading to optimized methods for clinical care in the future.

SPRINGER NATURE RETRACTS 75 PAPERS OVER CITATION MANIPULATION

In response to allegations of citation manipulation by Juan Manuel Corchado, rector of the University of Salamanca (Usal), Springer Nature has retracted 75 conference papers linked to him. The retractions were prompted by reports of “unusual citation behavior,” with the papers citing Corchado 1,772 times, alongside numerous references to his journal and research group members. Experts noted the suspicious citation patterns, raising concerns about editorial integrity and undisclosed conflicts of interest, as many papers were published in conferences organized by Corchado’s group. This unprecedented mass retraction in Spain follows a report by bibliometricians Alberto Martín Martín and Emilio Delgado López-Cózar, who initially flagged the papers. While Corchado’s research group claimed to be correcting editorial errors, they also characterized the accusations as malicious. The Spanish Committee on Research Ethics has suggested disciplinary action, but Corchado’s position as rector complicates potential consequences. The broader implications for the reputation of Spanish science remain concerning, with calls for accountability and responsible research practices. (Science)

FORMER MORTICIAN RESEARCHES ANCIENT BRAIN PRESERVATION MYSTERIES

Alexandra Morton-Hayward, a 35-year-old former mortician turned molecular palaeontologist, is on a quest to understand the preservation of ancient brains. After driving through a storm in Belgium, she is collecting 37 brains from a medieval graveyard, adding to her extensive collection of over 600 ancient specimens, some as old as 12,000 years. At Oxford, she studies how certain brains survive without embalming, employing techniques like mass spectrometry and particle accelerators. Her research may unlock mysteries of brain decay and preservation, possibly reshaping our understanding of neurodegenerative diseases. Morton-Hayward’s passion for this field stems from her own experiences with debilitating cluster headaches, which she likens to “suicide headaches.” Despite her health struggles, she perseveres, fascinated by the molecular processes that allow these ancient brains to remain intact. The irony lies in the fact that many preserved brains come from individuals who faced significant suffering in life, raising questions about the relationship between physiological stress and preservation. As she collects more specimens, Morton-Hayward continues to confront the complexities of life, death, and the enduring mysteries of the human brain. (The Guardian)

SOUTHEAST ASIA FACES FOSSIL FUEL RELIANCE AMID ELECTRICITY DEMAND

Southeast Asia risks increasing its reliance on fossil fuels amid rising electricity demand, according to a report from the environmental think tank Ember. Last year, the region’s 3.6% surge in electricity demand was met entirely through fossil fuels, while renewable energy’s share dropped from 28% to 26% due to decreased hydropower production from droughts and extreme weather. This shift contributed to a 6.6% rise in carbon emissions, adding 44 million tonnes of CO2 to the atmosphere, with Vietnam, Malaysia, and the Philippines being the largest coal polluters. Ember warned that the slow transition to clean energy technologies like solar and wind could hinder ASEAN’s climate targets and economic opportunities. The International Energy Agency (IEA) estimates that Southeast Asia must invest $190 billion—five times its current investment rate—to meet climate goals by 2035. As electricity demand is projected to grow at 4% annually, institutional barriers and conflicting energy priorities complicate the region’s shift to renewables. (Al-Jazeera)

JAPAN TAKES STEPS TO REDUCE FOOD WASTE AMIDST CHALLENGES

Efforts to combat food waste are gaining traction in Japan, as a recent survey by the Consumer Affairs Agency reveals that 43% of processed food products had their expiration or best-before dates extended. While larger companies have actively embraced this initiative, over half of small businesses have no plans to follow suit, citing challenges in maintaining product quality and managing costs. The Japanese government aims to halve food waste by fiscal 2030 compared to fiscal 2000. Data from fiscal 2022 shows that the business sector has already met this goal, although household waste remains an issue. The survey categorized companies based on size, with 53% of small businesses (fewer than 20 employees) indicating no intention to extend expiration dates, compared to 29% of small- to medium-sized firms and 15% of large companies. Challenges noted included quality and safety concerns related to seasonal variations and consumer handling. (Japan Today)

STUDY REVEALS GENOMIC DISPARITIES IN GLOBAL BIODIVERSITY CONSERVATION

A new study published in Molecular Evolution highlights a significant disparity in genomic representation between the Global North and South concerning biodiversity. Although tropical regions in the Global South boast greater animal species diversity, species from the Global North are more frequently included in genomic databases essential for conservation decisions. The research surveyed 21,583 land species and found that reference genomes are present for 38% of species in the Northern Hemisphere compared to just 24% in the Southern Hemisphere. For instance, despite the western Amazon basin in Ecuador being rich in biodiversity, it lacks adequate reference genomes. Additionally, a review of 394 papers in conservation genetics journals revealed only 16% had authors from the Global South, reflecting inequities in scientific capacity and access to sequencing technology. Researchers advocate for more inclusive international collaborations and increased investment in local research infrastructure to empower scientists in the Global South and improve biodiversity conservation efforts.
