When tested, colonies fed this supplement produced up to 15 times more young. The findings were published in the journal Nature.

` * *Data:* up to 15 times more young (幼蜂数量增加了多达15倍). "Young" here refers to brood/larvae. * *Source:* journal *Nature* (《自然》期刊). * *Draft:* 测试显示，喂食这种补充剂的蜂群产出的幼蜂数量增加了多达15倍。该研究结果发表在《自然》期刊上。 * **Segment 3:** `

Bees Are Starving for the Right Nutrients

` * *Headline:* Starving for the Right Nutrients (因缺乏合适营养素而挨饿/渴望正确的营养素). "Starving for" implies a lack of specific things needed. * *Draft:* 蜜蜂因缺乏合适的营养素而挨饿 (or slightly more idiomatic: 蜜蜂亟需合适的营养素). Let's stick to the meaning of nutritional starvation. "蜜蜂正因缺乏合适的营养素而处于饥饿状态" is a bit long. "蜜蜂缺乏所需的关键营养素" is good but misses the "starving" nuance. Let's go with: **蜜蜂因缺乏合适营养素而挨饿** or **蜜蜂正“挨饿”以获取合适的营养素**. The context is they have calories but not the right stuff. Let's use: **蜜蜂因缺乏合适营养素而处于饥饿状态** (captures the paradox). Or simply: **蜜蜂缺乏合适的营养素**. Let's look at the next paragraph. It talks about reliance on pollen. Let's try: **蜜蜂亟需合适的营养素**. Actually, "Starving for" is a strong metaphor. Let's translate it as: **蜜蜂因缺乏合适营养素而挨饿**. * **Segment 4:** `

Honeybees rely on pollen as their main food source. It contains essential lipids called sterols that are critical for growth and development.

` * *Terms:* Honeybees (蜜蜂), pollen (花粉), lipids (脂质), sterols (甾醇), critical for growth and development (对生长发育至关重要). * *Draft:* 蜜蜂依靠花粉作为其主要食物来源。花粉含有被称为甾醇的必需脂质，这些物质对生长发育至关重要。 * **Segment 5:** `

But climate change and intensive farming have reduced the variety of flowers bees depend on. As a result, bees are increasingly missing key nutrients.

` * *Terms:* intensive farming (集约化农业/密集农业), variety of flowers (花卉种类/花朵多样性). * *Draft:* 但气候变化和集约化农业减少了蜜蜂依赖的花卉种类。因此，蜜蜂越来越缺乏关键营养素。 * **Segment 6:** `

Beekeepers often use artificial pollen substitutes made from protein flour, sugars, and oils. These provide calories but lack the sterols bees need, leaving colonies nutritionally deficient.

` * *Terms:* artificial pollen substitutes (人工花粉替代品), protein flour (蛋白粉), sugars (糖类), oils (油脂), nutritionally deficient (营养缺乏/营养不良). * *Draft:* 养蜂人通常使用由蛋白粉、糖类和油脂制成的人工花粉替代品。这些替代品提供了热量，但缺乏蜜蜂所需的甾醇，导致蜂群营养不良。 * **Segment 7:** ` ` (Skip, HTML tag). * **Segment 8:** `

A Lab-Made Solution Using Engineered Yeast

` * *Headline:* Lab-Made Solution (实验室制备的解决方案), Engineered Yeast (工程酵母). * *Draft:* 利用工程酵母的实验室解决方案 * **Segment 9:** `

To fill this gap, researchers engineered the yeast Yarrowia lipolytica to produce a precise mix of six essential sterols.

` * *Terms:* Yarrowia lipolytica (解脂耶氏酵母), precise mix (精确混合物/配比). * *Draft:* 为了填补这一空白，研究人员对解脂耶氏酵母进行了基因工程改造，以产生六种必需甾醇的精确混合物。 * **Segment 10:** `

They added this yeast to bee diets and tested it over three months in controlled glasshouse experiments. The enclosed setup ensured bees ate only the experimental feed.

` * *Terms:* controlled glasshouse experiments (受控温室实验), enclosed setup (封闭环境/装置), experimental feed (实验饲料). * *Draft:* 他们将这种酵母添加到蜜蜂饲料中，并在受控温室实验中进行了为期三个月的测试。这种封闭设置确保蜜蜂只食用实验饲料。 * **Segment 11:** `

Colonies Grew Faster and Stayed Healthier

` * *Headline:* Colonies (蜂群). * *Draft:* 蜂群生长更快且更健康 * **Segment 12:** `

The results were dramatic. Colonies receiving the enriched diet produced up to 15 times more larvae that reached the pupal stage compared with those on standard diets.

` * *Terms:* enriched diet (强化饮食/富含营养的饮食), larvae (幼虫), pupal stage (蛹期), standard diets (标准饮食). * *Draft:* 结果非常显著。与食用标准饮食的蜂群相比，食用这种强化饮食的蜂群产出的能够发育到蛹期的幼虫数量多达前者的15倍。 (注明: "produced up to 15 times more... compared with" means the ratio is 15:1. "多达15倍" is correct). * **Segment 13:** `

They also continued raising brood throughout the entire study period. Colonies without sterols stopped producing brood after about 90 days.

` * *Terms:* raising brood (育虫/抚育幼虫), brood (子脾/幼虫). * *Draft:* 它们还在整个研究期间持续育虫。而缺乏甾醇的蜂群在大约90天后停止了育虫。 * **Segment 14:** ` ` (Skip, HTML tag). * **Segment 15:** `

Even more striking, the nutrient profile of larvae matched that of bees feeding naturally, suggesting the supplement closely replicates real pollen nutrition.

` * *Terms:* nutrient profile (营养概况/营养特征), feeding naturally (自然觅食/自然饮食). * *Draft:* 更引人注目的是，幼虫的营养特征与自然觅食的蜜蜂相匹配，这表明该补充剂非常接近地复制了真实花粉的营养。 * **Segment 16:** `

Scientists Say This Could Be a Game Changer

` * *Headline:* Game Changer (颠覆者/改变游戏规则的事物/重大突破). * *Draft:* 科学家称这可能是一项颠覆性的突破 * **Segment 17:** `

Senior author Professor Geraldine Wright (Department of Biology, University of Oxford), said: "Our study demonstrates how we can harness synthetic biology to solve real-world ecological challenges. Most of the pollen sterols used by bees are not available naturally in quantities that could be harvested on a commercial scale, making it otherwise impossible to create a nutritionally complete feed that is a substitute for pollen"

` * *Terms:* Senior author (资深作者/通讯作者 - usually corresponding author, but senior author is fine as 资深作者), synthetic biology (合成生物学), commercial scale (商业规模), nutritionally complete feed (营养完全的饲料). * *Draft:* 资深作者、牛津大学生物系的杰拉尔丁·赖特（Geraldine Wright）教授表示：“我们的研究展示了如何利用合成生物学来解决现实世界的生态挑战。蜜蜂使用的大多数花粉甾醇在自然界中无法以可商业 * *Draft:* 为了弄清蜜蜂到底需要什么，研究人员分析了蛹和成年蜜蜂的组织。这需要极其精细的实验室工作，包括解剖单个哺育蜂。 * *Refinement:* "Pupae" -> 蛹.

"Programmed" -> 编程/改造. "改造" is often used in biotech contexts, but "编程" fits the "programmed" source text well. Let's stick to "编程" or "设计". "对...进行编程" works. * **Paragraph 4:** This yeast was chosen because it naturally produces lipids, is safe for food use, and can be scaled up for industrial production. The final supplement is made by growing the yeast in bioreactors and drying it into a powder. * *Draft:* 之所以选择这种酵母，是因为它天然产生脂质，食用安全，且可扩大规模进行工业生产。最终的补充剂是通过在生物反应器中培养酵母并将其干燥成粉末制成的。 * *Refinement:* "Lipids" -> 脂质. "Safe for food use" -> 食用安全. "Bioreactors" -> 生物反应器. The translation is accurate. * **Title:** Why This Matters for Food and Farming * *Draft:* 这对粮食与农业的重要性 * *Refinement:* Or "为何这对粮食与农业至关重要". The latter flows better. * **Paragraph 5:** Honeybees help produce more than 70% of major global crops. But their populations are under severe pressure from poor nutrition, climate change, parasites, disease, and pesticides. * *Draft:* 蜜蜂协助生产了全球70%以上的主要农作物。但其种群正面临营养不良、气候变化、寄生虫、疾病和农药带来的巨大压力。 * *Refinement:* "Major global crops" -> 全球主要农作物. "Severe pressure" -> 严重压力/巨大压力.

It may even evolve into a complete nutritional feed. * *Draft:* 这种新型补充剂可以增强蜜蜂的健康，且不会增加对有限野花的竞争。它甚至可能演变成一种全价营养饲料。 * *Refinement:* "Competition for limited wildflowers" -> 对有限野花资源的竞争. "Complete nutritional feed" -> 全价营养饲料 (Standard term in animal husbandry). * **Title:** Helping Wild Bees Too * *Draft:* 亦能惠及野生蜜蜂 * *Refinement:* Concise and accurate. * **Paragraph 8:** Co-author Professor Phil Stevenson (RBG Kew and Natural Resources Institute, University of Greenwich) added: "Honey bees are critically important pollinators for the production of crops such as almonds, apples, and cherries and so are present in some crop locations in very large numbers, which can put pressure on limited wildflowers. Our engineered supplement could therefore benefit wild bee species by reducing competition for limited pollen supplies." * *Draft:* 合著者、（英国皇家植物园邱园及格林威治大学自然资源研究所）菲尔·史蒂文森教授补充道：“蜜蜂是杏仁、苹果和樱桃等农作物生产中至关重要的授粉者，因此在某些作物种植区数量巨大，这可能给有限的野花带来压力。因此，我们通过工程手段制备的补充剂可以通过减少对有限花粉资源的竞争，使野生蜜蜂物种受益。” * *Refinement:* "RBG Kew" -> 英国皇家植物园邱园.

"Pollen supplies" -> 花粉资源/供应. * **Title:** A Potential Breakthrough for Beekeepers * *Draft:* 养蜂人的潜在突破 * *Refinement:* Or "养蜂业的潜在突破". "Beekeepers" specifically refers to the people. "养蜂人" is accurate. * **Paragraph 9:** Danielle Downey (Executive Director of honeybee research nonprofit Project Apis m., not affiliated with the study) said: "We rely on honey bees to pollinate one in three bites of our food, yet bees face many stressors. Good nutrition is one way to improve their resilience to these threats, and in landscapes with dwindling natural forage for bees, a more complete diet supplement could be a game changer. This breakthrough discovery of key phytonutrients that, when included in feed supplements, allow sustained honey bee brood rearing has immense potential to improve outcomes for colony survival, and in turn the beekeeping businesses we rely on for our food
