数千年来，阿拉斯加北坡的野火一直很少见。这一情况在20世纪发生了急剧变化，气温升高使土壤变得干燥，并促进了灌木丛的蔓延，为剧烈火灾创造了条件。泥炭岩芯和卫星数据显示，自1950年代以来，火灾活动已达到创纪录水平。这些发现表明，北极地区正在进入一个全新的、更加危险的火灾时代。

研究人员发现了一种罕见的新型糖尿病，该疾病在婴儿早期发病。此病症由单基因突变引发，导致产胰岛素细胞功能失常。当这些细胞失效时，血糖水平升高并引发糖尿病，通常还伴随神经系统问题的出现。这一发现不仅有助于解释长期存在的医学谜团，也深化了人们对糖尿病整体机制的认知。

暗物质作为宇宙最重大的谜团之一，其诞生时可能处于炽热状态，而非科学家长期认为的寒冷迟缓。最新研究表明，暗物质粒子在大爆炸后不久可能以接近光速运动，之后才逐渐冷却，并持续参与星系形成过程。通过聚焦于被称为“暴胀后重加热”的混沌早期宇宙阶段，研究人员揭示这种“炽热”暗物质能够存续足够长时间，最终演变为我们今天观测到的、平静且构建结构的力。

科学家们新近识别出一种暗藏于海洋表面之下的威胁：可能持续数日甚至数月的水下突发性黑暗现象。这些被称为"海洋暗波"的事件由风暴、沉积物径流、藻华与水体混浊共同引发，会急剧减少抵达海底的光照量，使海藻林、海草床及其他依赖光照的生物群体面临生存危机。

By analyzing tooth enamel chemistry, scientists uncovered proof that Jurassic dinosaurs divided up their meals in surprising ways—some choosing buds and leaves, others woody bark, and still others a mixed menu. This dietary diversity helped massive plant-

New research from Denmark challenges long-held assumptions about body weight and health, revealing that being overweight—or even moderately obese—does not necessarily increase the risk of death compared to those at the upper end of the "normal" BMI rang

A massive study of over 4 million adults has revealed that cannabis use may nearly quadruple the risk of developing diabetes. Despite some earlier suggestions that cannabis might have metabolic benefits, this large analysis found significantly higher diab

Dry eyes are far more common than previously believed, with over half of adults in the US and Europe experiencing symptoms, yet most remain undiagnosed for years. The large-scale NESTS study reveals that sufferers often endure daily discomfort that disrup

Eye drops combining pilocarpine and diclofenac helped patients read extra lines on vision charts, with effects lasting up to two years. The treatment could revolutionize presbyopia care as a safe, non-surgical alternative to glasses.

Researchers discovered two new parasitic wasp species living in the U.S., tracing their origins back to Europe and uncovering clues about how they spread. Their arrival raises fresh questions about biodiversity, ecological risks, and the role of citizen s

Nature has long been the source of lifesaving medicines, from willow bark’s natural aspirin to new discoveries in tropical fruits. Now, chemists at the University of Delaware have pioneered a way to recreate powerful molecules from guava plants that show
