Microbiologist Antoni van Leeuwenhoek's groundbreaking observations of single-celled organisms are detailed in a new biography by historian Geertje Dekkers, published by Reaktion in 2025. The book, "Myriad, Microscopic and Marvellous," recounts van Leeuwenhoek's 1674 discovery of bacteria and protozoa in lake water, viewed under a microscope. According to the biography, van Leeuwenhoek also accurately described red blood cells, capillaries, striated muscle fibers, spermatozoa, and the crystalline lens of the eye.
Van Leeuwenhoek's contributions were recognized by the UK Royal Society, which mourned the loss of its "most valuable correspondent" upon his death in 1723. His work laid the foundation for modern microbiology and significantly advanced the understanding of human biology.
In related news, anthropologists Melissa Leach and James Fairhead explore the interconnectedness of humans and the natural world in their book, "Naturekind," published by Princeton University Press in 2025. The authors delve into biosemiotics, linking biological findings to the study of meaning in sign systems. "Naturekind" examines human interactions with various living entities, including chickens, horses, bees, bats, and plants, within diverse environments such as forests, seas, soils, and cities. The book considers both living and non-living entities, emphasizing the complex relationships between humans and their surroundings.

Research indicates that the speed and effectiveness of nasal cell antiviral defenses determine the severity of a cold, suggesting the body's immune response is more critical than the virus itself. This finding has implications for understanding individual susceptibility to rhinovirus and developing targeted therapies to bolster these natural defenses, potentially reducing the impact of common colds and related respiratory issues.
A recent study in *Alzheimer's & Dementia* reveals that individuals maintaining exceptional cognitive function into their 80s, known as "super agers," possess a genetic advantage. Researchers observed a significantly lower prevalence of the APOE-ε4 Alzheimer's risk gene and a higher occurrence of the protective APOE-ε2 variant in this group, suggesting a genetic basis for their cognitive resilience and offering potential targets for future Alzheimer's prevention strategies.
A novel blood test shows promise in detecting Crohn's disease years before symptom onset by identifying heightened immune responses to gut bacteria. Experts suggest this early detection could lead to timely interventions, potentially preventing severe disease progression and improving patient outcomes through proactive management.
New research indicates that long-term type 2 diabetes can alter red blood cells, impairing blood vessel function and increasing cardiovascular risk. Experts at the Karolinska Institutet identified a specific molecule within these cells that may serve as an early biomarker for rising heart risks, offering potential for proactive monitoring and intervention in diabetic patients. These findings underscore the importance of managing diabetes duration to mitigate its impact on cardiovascular health.
Vietnam's Communist Party re-elected To Lam as General Secretary, signaling a potential shift towards consolidated leadership reminiscent of China and Laos, as analysts anticipate he will also assume the presidency. This move, breaking from the country's tradition of collective leadership, aims to accelerate economic growth towards a targeted 10%, while also raising concerns about checks on power within the party. The political development occurs as Vietnam seeks to elevate its economic status on the global stage.
Social media weather influencers are gaining popularity, offering real-time updates and analysis, but their reliability varies greatly, raising concerns about the accuracy and potential misinformation spread by non-experts.
