Researchers have found that a mutant strain of sake yeast produces high levels of the amino acid ornithine. Ornithine has been found to reduce fatigue and improve sleep quality, and the non-genetically modified mutant yeast strain discovered in this study could be easily applied to brewing sake, a traditional Japanese alcoholic beverage, as well as wine and beer.

Words to stress correctly
| traditional | tra·DI·tion·al | /trəˈdɪʃənəl/ |
| alcoholic | al·co·HOL·ic | /ælkəˈhɑlɪk/ |
| discovered | dis·COV·ered | /dɪˈskʌvɚd/ |
| produces | pro·DUC·es | /prəˈdusəz/ |
| japanese | ja·pa·NESE | /dʒæpəˈniz/ |
58 words, aim for 22–26 seconds, no numbers. Breathe after ornithine, after sleep quality and after brewing sake; short pauses after yeast, study and beverage.
Where marks are usually lost
Stress al·co·HOL·ic and ja·pa·NESE late, but tra·DI·tion·al, dis·COV·ered, pro·DUC·es on the second syllable. Don't hesitate inside non-genetically modified mutant yeast strain—say it as one phrase. Keep the -s in produces, levels and the -ed in discovered, applied, modified.
General tip: ornithine appears twice; decide on OR-ni-theen before you start and say it the same way both times.

中文: 研究人员发现，一种清酒酵母的突变菌株能产生高水平的氨基酸鸟氨酸。鸟氨酸已被发现能减轻疲劳、改善睡眠质量，而这项研究中发现的这种非基因改造的突变酵母菌株，可以很容易地应用于酿造清酒——一种日本传统酒精饮料——以及葡萄酒和啤酒。
हिन्दी: शोधकर्ताओं ने पाया है कि साके यीस्ट की एक उत्परिवर्तित (म्यूटेंट) किस्म अमीनो एसिड ऑर्निथीन उच्च मात्रा में बनाती है। ऑर्निथीन थकान कम करने और नींद की गुणवत्ता सुधारने में सहायक पाया गया है, और इस अध्ययन में खोजी गई यह गैर-आनुवंशिक रूप से संशोधित म्यूटेंट यीस्ट किस्म साके—एक पारंपरिक जापानी मादक पेय—तथा वाइन और बीयर बनाने में आसानी से इस्तेमाल की जा सकती है।
नेपाली: अनुसन्धानकर्ताहरूले साके यीस्टको एउटा उत्परिवर्तित (म्युटेन्ट) प्रजातिले अमिनो एसिड ओर्निथिन उच्च मात्रामा उत्पादन गर्ने पत्ता लगाएका छन्। ओर्निथिनले थकाइ घटाउने र निद्राको गुणस्तर सुधार्ने पाइएको छ, र यस अध्ययनमा पत्ता लागेको यो आनुवंशिक रूपमा परिमार्जन नगरिएको म्युटेन्ट यीस्ट प्रजाति साके—एक परम्परागत जापानी मादक पेय—साथै वाइन र बियर बनाउन सजिलै प्रयोग गर्न सकिन्छ।
Tiếng Việt: Các nhà nghiên cứu phát hiện một dòng nấm men sake đột biến tạo ra hàm lượng cao axit amin ornithine. Ornithine đã được chứng minh giúp giảm mệt mỏi và cải thiện chất lượng giấc ngủ, và dòng nấm men đột biến không biến đổi gen được phát hiện trong nghiên cứu này có thể dễ dàng áp dụng vào việc ủ sake—một loại đồ uống có cồn truyền thống của Nhật—cũng như rượu vang và bia.
