      "title": "Is Bruce Lee invincible? Revealed: What kind of opponent scares him?",
      "body": "1, Bruce Lee, the name is known in the martial arts world, his kung fu and philosophy have influenced generation after generation. However, in his later years, the seemingly fearless martial arts legend is revealed by his wife Linda that he actually has a special opponent to fear.\n\n![屏幕截图 2024-08-20 165657.png](https://cdn.steemitimages.com/DQmPm8PDTMzPkJsee5AAAqoTW2afgU83ag2cWkMpcNqzXci/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165657.png)\n\n2, in Bruce Lee's martial arts career, he has faced a variety of challenges, whether from different schools of martial arts masters, or the test of street combat, he has a superb skill and extraordinary wisdom to overcome one by one. However, according to Linda later revealed that Bruce Lee, deep down in his heart, felt a particular fear of an opponent, that is, time.\n\n![屏幕截图 2024-08-20 165710.png](https://cdn.steemitimages.com/DQmepMVw11rnepWY3UVBhTopS2DoB6vdnwKNWXCDj2qvfK8/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165710.png)\n\n3, Time, this seemingly abstract concept, but Bruce Lee can not beat the opponent. He knew that his skill, no matter how great, could not resist the passage of time. He feared that his body would age over time and that his skills would deteriorate over time. This fear of time makes him work harder on the road of martial arts and cherish every practice and fight more.\n\n![屏幕截图 2024-08-20 165733.png](https://cdn.steemitimages.com/DQmV4Lfg4Kr3fEaGAreNmRDLZXpC7Zyq7mgH8hL9h7HydxS/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165733.png)\n\n4, Bruce Lee's fear is actually a profound understanding of the impermanence of life. He knew that no matter how powerful he was, he could not escape the laws of life. Therefore, he chose to challenge the limits of life with martial arts and explore the meaning of life with philosophy. His martial arts and philosophy are his response to the impermanence of life, his struggle against the invincible opponent of time.\n\n5. So, how did Bruce Lee deal with this fear? His answer is -- keep moving. He knows that he can't defeat time, but he can choose how to face time. He chose to challenge himself and surpass himself to make his life meaningful. His martial arts and philosophy are his weapons against time, his armor against the impermanence of life.\n\n![屏幕截图 2024-08-20 165801.png](https://cdn.steemitimages.com/DQmXjdtDYkaZQxCioeCtSYq7xc2BfrUnv7jsQy3mdbt2HDx/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165801.png)\n\n6, Bruce Lee's fear, not only did not let him back down, but became his driving force forward. He used his own life to prove that even in the face of an invincible opponent, you can choose to face it bravely, and use your own way to challenge and surpass. His story tells us that the meaning of life is not to defeat opponents, but how to face challenges, how to surpass ourselves.\n7. Bruce Lee's life was full of love for martial arts and reverence for life. His fear made him cherish every practice and fight more, and let him keep moving forward on the road of martial arts. His story, let us see a real Bruce Lee, a Bruce Lee with his own fears and challenges. His fear, instead of weakening his image, made him more real, more flesh and blood.\n\n![屏幕截图 2024-08-20 165812.png](https://cdn.steemitimages.com/DQmdssrzBqEPAwzFXqHZ5ydqTWZtKrwnRCokVxFhbgHnF16/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165812.png)\n\n8. So, what about us? Do we also have our own \"soft underbelly\", whether we can also be like Bruce Lee, brave to face, with their own way to challenge, to surpass? This is the lesson of Bruce Lee's story and his legacy. Let us take this problem, to think, to explore, to find their \"soft underbelly\", to face bravely, to surpass themselves.\n![屏幕截图 2024-08-20 165747.png](https://cdn.steemitimages.com/DQmajfVsc7xe5C1tPBEd7eaXzDYMbHk6bXhPnDZeRdoXYFw/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165747.png)",

      "body": "Have you ever heard of the Tibetan antelope 🐐?\nThey're the superheroes of the prairie! Tibetan antelope has a pair of gorgeous horn crown, whenever they run on the grassland, it is like jumping a happy dance!\nTibetan antelope are herbivores 🌱, like to eat grass, and run super fast! Although there are some fierce beasts on the grassland, the crested antelopes are resourceful and can always avoid danger. They play with their friends and are the most beautiful scenery on the grassland ⛰️.\n\nPART-01 Key roles on the grassland ✨\n- Rich foraging behavior\nTibetan antelope are mainly herbivorous, and their keen sense of smell and flexible body allow them to quickly catch rich food resources in the grasslands. Their foraging behavior on the grassland not only satisfies their own survival needs, but also plays a key role in maintaining the ecological balance of the grassland.\n- Maintaining ecological balance in grasslands\nThe foraging behavior of Tibetan antelope helps to control the growth of grassland vegetation and prevent the excessive overgrowth of grass from putting competitive pressure on the living space of other species. Their activities in the grassland also promote the renewal of plants and the fertility of the soil, providing a good living environment for other plants and animals.\n- Defense strategy.\nTibetan antelope are known for their excellent speed and agility on the grasslands. When faced with a predator, they will quickly flee and adopt unique defensive strategies, such as rapid changes in direction, sudden stops, etc., to avoid the pursuit of predators.\n- Group behavior and ecological landscape\nTibetan antelope usually live in groups, and their group behavior shows a spirit of solidarity and cooperation. When they run together on the grassland, they form a spectacular scene and form a unique grassland ecological landscape, which brings unlimited surprises and moves to people.\n\n![屏幕截图 2024-08-20 165049.png](https://cdn.steemitimages.com/DQmQ1B7ixWLpp3XfCqdFJ3EtCNbKwZfpdNiMUa24VGMeVxF/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165049.png)\n\nPART-02 Tibetan Antelope and grassland 🧚🏻‍♀️\nGrassland ecosystems are one of the most important habitats for life on Earth. As a key species in the grassland ecosystem, Tibetan antelope plays an important role in maintaining ecological balance. Their presence helps control the growth of grassland vegetation and prevents overgrown grass from putting competitive pressure on other species for space. In addition, grassland vegetation can also fix soil, prevent soil erosion, maintain water sources, and play an important role in maintaining the stability of the Earth's ecosystem.\n- Enhanced protection measures\n- Control grazing scale\n- Manage water resources scientifically\n- Promoting climate change response\n\n![屏幕截图 2024-08-20 165103.png](https://cdn.steemitimages.com/DQmUu7Wdnjr6scQ7ZggnSdLmpVMsXAshk2Ccw6diaXGcjYN/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165103.png)\n\nPART-03 Challenges of grassland ecology 🧟\nThe challenges facing grassland ecosystems are also serious. Human activities such as climate change and overgrazing have had a serious impact on grassland ecosystems. If we do not take effective measures to protect and manage, it will pose a serious threat to the ecological balance of the grassland.\n\n![屏幕截图 2024-08-20 165118.png](https://cdn.steemitimages.com/DQmas9TN55pStD6vXdrpPkgLRSG5PFwkUJq6YmAUhJ1KfJo/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165118.png)\n\nDo you have any other stories about Tibetan antelope? 🍀\nLeave a comment and join us in speaking out for this mysterious and precious animal!\n![屏幕截图 2024-08-20 165133.png](https://cdn.steemitimages.com/DQmZ3qF4eH5CgDh7S7CqjrcPzBrbAev6o6yTeLmTKfPPn7i/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165133.png)\n\n![屏幕截图 2024-08-20 165147.png](https://cdn.steemitimages.com/DQmUASC31Vs2fzsHtRH7HTgKcvnFhY5hvcQ1Mmgb5rwVn3C/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-20%20165147.png)",

      "body": "تجذب الثقافة العربية الانتباه من جميع أنحاء العالم بفضل تاريخها العريق وتقاليدها الغنية. كجزء مهم من الحضارة العالمية، لم تؤثر فقط في التاريخ القديم، ولكنها تحتل مكانة هامة أيضًا في العالم الحديث. اليوم، دعونا نستكشف سحر الثقافة العربية، من جذورها، دينها، فنونها، إلى حياتها الحديثة.\n\nأولاً، يمكن إرجاع جذور الثقافة العربية إلى شبه الجزيرة العربية قبل الميلاد، حيث ازدهرت العديد من الحضارات القديمة مثل حضارة سبأ وحضارة الأنباط. اللغة العربية هي جوهر هذه الثقافة، وتُعد من بين أكبر خمس لغات في العالم، ولا تزال حتى اليوم اللغة الرسمية للعديد من البلدان في الشرق الأوسط وشمال أفريقيا. وبما أن القرآن الكريم كُتب باللغة العربية، فإن للغة العربية ارتباطًا عميقًا بالإسلام.\n\nالثقافة العربية والإسلام متشابكان بشكل لا ينفصل. فالإسلام ليس مجرد ديانة، بل يؤثر بعمق على نمط حياة العرب. يؤدي المسلمون صلواتهم خمس مرات يوميًا، وهو ليس فقط واجبًا دينيًا، ولكنه أيضًا تعبير عن الروحانية في الثقافة العربية. شهر رمضان هو الشهر المقدس في الإسلام، وفيه يصوم المسلمون تأكيدًا على الانضباط الذاتي وتطهير الروح. بالإضافة إلى ذلك، يشتهر العالم العربي بكرم ضيافته، حيث يعتبر إكرام الضيف شرفًا. هذا التقليد ينعكس في طريقة استقبالهم للضيوف، وخاصة من خلال المأكولات العربية الغنية مثل المشويات والحمص والتمر.\n\nفي مجال الفن والعمارة، تتميز الثقافة العربية بأسلوبها الفريد. العمارة الإسلامية مشهورة بنقوشها الهندسية الجميلة والخط العربي، ومن أمثلة العمارة العربية المتميزة قصر الحمراء في إسبانيا والمسجد الحرام في مكة المكرمة. يشتهر فن الخط العربي بجمال منحنياته وتصميماته الرائعة، ويُستخدم هذا الفن لتزيين المباني والمخطوطات الدينية.\n\nومع ذلك، لا تقتصر الثقافة العربية على التقاليد فقط، بل تدمج أيضًا عناصر حديثة. العديد من الدول العربية تشهد تطورًا سريعًا، وأصبحت مدن مثل دبي وأبوظبي مراكز اقتصادية وثقافية عالمية. الشباب العرب يدمجون بين التقاليد والحداثة ليشكلوا أسلوبًا فريدًا في الأزياء والموسيقى والترفيه. خاصة على وسائل التواصل الاجتماعي، أصبحت الثقافة العربية أكثر انتشارًا وتقديرًا على نطاق واسع.\n\nبالمجمل، الثقافة العربية هي مزيج من القديم والحديث، وتحمل في طياتها تاريخًا غنيًا، إيمانًا دينيًا، تقاليد فنية، وابتكارات في الحياة المعاصرة. إنها مليئة بالغموض والسحر، حيث يكتشف الناس فيها دائمًا مفاجآت جديدة. في عصر العولمة اليوم، تتفاعل الثقافة العربية مع الثقافات الأخرى في العالم، وتستمر في إظهار تنوعها وتفردها.\n\nنأمل أن تكون هذه المقالة قد أضافت إلى معرفتكم عن الثقافة العربية، ونتطلع إلى أن تشاركونا مشاهداتكم وآرائكم حول الثقافة العربية في قسم التعليقات!\n![屏幕截图 2024-08-19 134357.png](https://cdn.steemitimages.com/DQmStPgFVQMZuf1XRmkmsAszB8X91bQmpVkNakvNGMmBmvs/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134357.png)\n\n![屏幕截图 2024-08-19 134411.png](https://cdn.steemitimages.com/DQmd21JSmFS1tuy7MJRCfN3hfa7ktdVem4NWXTVBc257SV9/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134411.png)\n\n![屏幕截图 2024-08-19 134503.png](https://cdn.steemitimages.com/DQmVLHQF2EAmgq93AQy12wBCRe1Zq6pGkaGSrNJUYmLJE3Y/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134503.png)\n\n![屏幕截图 2024-08-19 134424.png](https://cdn.steemitimages.com/DQmVy57GdjzfJimB56Hmz7QiAwx2yhxV4pE5fB3qNkMoH3u/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134424.png)\n\n![屏幕截图 2024-08-19 134436.png](https://cdn.steemitimages.com/DQmW7VE5L2A4s5FiKvoA3xk3rBG7HZyRz5eAw6qbSWr7DRj/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134436.png)\n\n![屏幕截图 2024-08-19 134524.png](https://cdn.steemitimages.com/DQmR4GsH2UWnHb59gAEFHrhvcgWG66ez8RuXAJLJ1tc6HRX/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20134524.png)",

      "body": "In modern society, we are increasingly dependent on electronic devices, especially smartphones and computers, which become an integral part of our daily lives. However, this habit can have profound effects on our health. A recent study published in Nature Communications reveals a fascinating link between diet, eye health and longevity.\nThe research was carried out by a team led by Professor Pankaj Kapahi from the Buck Institute. They found that restricting the diet not only altered the flies' circadian rhythms, but also extended their lifespan. Although this finding has been verified in fruit flies, the biological mechanism behind it is thought-provoking. Every cell in our body has a rhythm control mechanism that responds to changes in our daily environment, such as light and temperature. These changes not only affect our behavior, but may also affect gene transcription and protein translation processes.\nProfessor Kapahi's team further found in the new study that the fruit fly's eyes play a key role in this process. In fruit flies on a restricted diet, photoreceptor neurons in their eyes showed rhythmic changes in the expression of many genes, the activation of which regulates life span. This shows that the eyes are not only our window to perceive the outside world, but also an important organ for regulating physiological rhythms.\nIn addition, studies have shown that reducing light stimulation to the eyes can extend the lifespan of fruit flies. This suggests a sensitivity of the eye and an active immune response. Long-term exposure to light can lead to degradation of photoreceptors and inflammation, which can affect health and longevity. In particular, Professor Kapahi noted that the use of electronic devices at night, especially in light polluted environments, may disrupt our circadian clock, damage vision, and have effects on the brain and the whole body.\nThis study reminds us that protecting our eyes is not only for eyesight, but also for overall health. The habit of using electronic devices at night may need to be reconsidered. Although the study's conclusions are based on experiments with fruit flies, the implications for us humans are self-evident. While enjoying the convenience brought by technology, we should also be concerned about its potential health risks.\nFinally, this study inspires us to further explore the link between eyes and health. The researchers hope to explore whether this link holds true for other organisms and how these findings can be applied to human health and longevity. Finding a balance between technology and nature is something we should all think about. After all that, maybe tonight we should cut down on the amount of time we spend on our devices at night and give ourselves a healthier night.\n![屏幕截图 2024-08-19 121237.png](https://cdn.steemitimages.com/DQmXsEWebH1X2fztRDJp8499dxEbnpexv1immTY1EzdBFQ3/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20121237.png)",

      "body": "Manhattan's history is full of exploration, colonization, construction and change. So is the history of Manhattan discovery:\n\nEarly exploration and colonization\n1609 - English explorer Henry Hudson first discovered Manhattan Island and named it. At this time, Manhattan Island was an unexplored wilderness with a rich ecological environment and a wide variety of wildlife.\n1624 - Dutch colonists begin to establish trading posts in Lower Manhattan, marking the official entry of Manhattan into the colonial era. The Dutch established basic order and rules here and tried to trade with the Indians.\n1626: The Dutch buy the land rights to Manhattan Island from the Indians at a very low price, a deal later criticized as blackmail, but which lays the foundation for Dutch colonial rule in Manhattan.\n\nDutch period\nDutch rule of Manhattan lasted about 40 years, a period that can be roughly divided into three phases:\nChaotic Freedom phase: The Dutch fleet established contact with the Indians, but there were frequent armed conflicts between merchant groups over resources.\nManhattan Dutch period: The West India Company is formed, with a monopoly on trade and navigation with North and South America and West Africa, military, legal and administrative privileges. The Dutch decided to establish a permanent settlement in Manhattan and sent engineers to build Fort New Amsterdam.\nOpening phase of commerce: As the West India Company's high monopoly was opposed, the New Netherlands gradually returned to the path of freedom, and Manhattan expanded rapidly to become the hub of North America.\n\nPeriod of British rule\n1664 - The English capture Manhattan from the Dutch and rename New Amsterdam \"New York\". Britain inherited the free trade mechanism pioneered by the Netherlands, and New York gradually developed into a free port.\n1785-1790 - New York City is the capital of the United States.\n\nModern development\nLate 19th century: The establishment of the Statue of Liberty marks the arrival of a new wave of immigrants in Manhattan, becoming a world symbol of American ideals of freedom and peace.\n1898 - Manhattan officially becomes one of the five boroughs of New York City.\nEarly 20th century: With the process of industrialization and urbanization, the population of Manhattan soared, and the architectural style began to be influenced by Europe, and a large number of European buildings emerged in Manhattan.\nModern: Manhattan has become one of the most prosperous business and financial centers in the world, with many world-famous landmarks, such as the Empire State Building and Rockefeller Center. Manhattan is also one of the most expensive real estate markets in the world, attracting investors and home buyers from all over the world.\n\nManhattan's history is an epic of exploration, colonization, construction, and transformation. The transformation from wilderness to bustling city has witnessed the progress and development of human civilization.\n![屏幕截图 2024-08-19 120544.png](https://cdn.steemitimages.com/DQmedvX6kcHuX1SNQ7FXJbTBvG18REndyb3jbTM5sTWkBwJ/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120544.png)\n\n![屏幕截图 2024-08-19 120602.png](https://cdn.steemitimages.com/DQmNwbXDkCawTJewabmsFbwvzQGh9p2jk2xFrT47kCdmiS6/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120602.png)\n\n![屏幕截图 2024-08-19 120618.png](https://cdn.steemitimages.com/DQmaqPT9GtgHMoSVvh8LBspxZdfKFxDWqs7w2r37XuEAvUJ/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120618.png)\n\n![屏幕截图 2024-08-19 120632.png](https://cdn.steemitimages.com/DQmcA7K4DBYVE3DZ5HaiPyS8gMQZGtjd4kAXaHSqgBpxJAD/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120632.png)\n\n![屏幕截图 2024-08-19 120647.png](https://cdn.steemitimages.com/DQmbxPuW36uzjPep8re6L7ZaLuRFk37Z2Vi1sMkcZTSnDM1/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120647.png)\n\n![屏幕截图 2024-08-19 120702.png](https://cdn.steemitimages.com/DQmdPdy1DHX36WZ2dVcE9NTMfF3egxfj6zhs3cV1wC6aA1h/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120702.png)\n\n![屏幕截图 2024-08-19 120718.png](https://cdn.steemitimages.com/DQmQKPnAY77pmoZhVBm43TTShbVfRhq6eFrgbS9qrWsaAzK/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120718.png)\n\n![屏幕截图 2024-08-19 120732.png](https://cdn.steemitimages.com/DQmTQHhyVkChXXaWpCR6kJ4M5FiwxJ26LHcJCXk5mv1Cs6W/%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE%202024-08-19%20120732.png)",

      "body": "Deep learning for protein design\nTwo decades ago, David Baker at the University of Washington in Seattle and his colleagues achieved a landmark feat: they used computational tools to design an entirely new protein from scratch. \"Top' folded as predicted, but it was inert: it performed no meaningful biological functions. Today, de novo protein design has matured into a practical tool for generating made-to-order enzymes and other proteins. \"It's hugely empowering,\" says Neil King, a biochemist at the University of Washington who collaborates with Baker's team to design protein-based vaccines and vehicles for drug delivery. \"Things that were impossible a year and a half ago — now you just do it.\"\nMuch of that progress comes down to increasingly massive data sets that link protein sequence to structure.\nBut sophisticated methods of deep learning, a form of artificial intelligence (Al), have also been essential.\nSequence based' strategies use the large language models (LLMs) that power tools such as the chatbot ChatGPT (see 'ChatGPT? Maybe next year'). By treating protein sequences like documents comprising polypeptide\n'words', these algorithms can discern the patterns that underlie the architectural playbook of real-world proteins. \"They really learn the hidden grammar,\" says Noelia Ferruz, a protein biochemist at the Molecular Biology Institute of Barcelona, Spain. In 2022, her team developed an algorithm called ProtGPT2 that consistently comes up with synthetic proteins that fold stably when produced in the laboratory. Another tool co-developed by Ferruz, called ZymCTRL, draws on sequence and functional data to design members of naturally occurring enzyme families.\nSequence-based approaches can build on and adapt existing protein features to form new frameworks, but they're less effective for the bespoke design of structural elements or features, such as the ability to bind specific targets in a predictable fashion.\nStructure based' approaches are better for this. and 2023 saw notable progress in this type of protein-designalgorithm, too. Some of the most sophisticated of these use 'diffusion' models, which also underlie image-generating tools such as DALL-E. These algorithms are initially trained to remove computer-generated noise from large numbers of real structures; by learning to discriminate realistic structural elements from noise, they gain the ability to form biologically plausible, user-defined structures.\nRFdiffusion software developed by Baker's lab and the Chroma tool by Generate Biomedicines in Somerville, Massachusetts, exploit this strategy to remarkable effect. For example, Baker's team is using RFdiffusion to engineer novel proteins that can form snug interfaces with targets of interest, yielding designs that \"just conform perfectly to the sur- face,\" Baker says. A newer\n'all atom' iteration of RFdiffusion allows designers to computationally shape proteins around non-protein targets such as DNA, small molecules and even metal ions. The resulting versatility opens new horizons for engineered enzymes,\ntranscriptional regulators, functional biomaterials and more.\n\nDeepfake detection\nThe explosion of publicly available generative Al algorithms has made it simple to synthesize convincing, but entirely artificial images, audio and video. The results can offer amusing distractions, but with multiple ongoing geopolitical conflicts and a US presidential election on the horizon, opportunities for weaponized media manipulation are rife.\nSiwei Lyu, a computer scientist at the University at Buffalo in New York, says he's seen numerous AI-generated 'deepfake' images and audio related to the Israel-Hamas conflict, for instance. This is just the latest round in a high-stakes game of cat-and-mouse in which Al users produce deceptive content and Lyu and other media-forensics specialists work to detect and intercept it.\nOne solution is for generative-Al developers to embed hidden signals in the models' output, producing watermarks of Al-generated content. Other strategies focus on the content itself. Some manipulated videos, for instance, replace the facial features of one public figure with those of another, and new algorithms can recognize artefacts at the boundaries of the substituted features, says Lyu. The distinctive folds of a person's outer ear can also reveal mismatches between a face and a head, whereas irregularities in the teeth can reveal edited lip-sync videos in which a person's mouth was digitally manipulated to say something that the subject didn't say. Al-generated photos also present a thorny challenge - and a moving target. In 2019, Luisa Verdoliva, a media-forensics specialist at University Federico II of Naples, Italy, helped to develop FaceForensics++, a tool for spotting faces manipulated by several widely used software packages. But image-forensic methods are subject- and software-specific, and generalization is a challenge. \"You cannot have one single universal detector — it's very difficult,\" she says.\nAnd then there's the challenge of implementation. The US Defense Advanced Research Projects Agencv's Semantic Forensics (Sema- For) programme has developed a useful tool- box for deepfake analysis, but, as reported in Nature (see Nature 621, 676-679; 2023) major social-media sites are not routinely employing it.\nBroadening the access to such tools could help to fuel uptake, and to this end Lyu's team has developed the DeepFake-O-Meter, a centralized public repository of algorithms that can analyse video content from different angles to sniff out deepfake content. Such resources will be helpful, but it is likely that the battle against Al-generated misinformation will persist for years to come.\n\nLarge-fragment DNA insertion\nIn late 2023, US and UK regulators approved the first-ever CRISPR-based gene-edit- ing therapy for sickle-cell disease and transfusion-dependent B-thalassaemia\n— a major win for genome editing as a clinical tool.\nCRISPR and its derivatives use a short programmable\nRNA to direct a DNA-cutting enzyme such as Cas9 to a specific genomic site. They are routinely used in the lab to disable defective genes and introduce small sequence changes. The precise and program- mable insertion of larger DNA sequences span- ning thousands of nucleotides is difficult, but emerging solutions could allow scientists to replace crucial segments of defective genes or insert fully functional gene sequences. Le Cong, a molecular geneticist at Stanford Uni- versity in California and his colleagues are exploring single-stranded annealing proteins (SSAPs) - virus-derived  molecules that mediate DNA recombination. When combined with a CRISPR-Cas system in which the DNA-slicing function of Case has been disabled, these SSAPs allow precisely targeted insertion of up to 2 kilobases of DNA into the human genome.\nOther methods exploit a CRISPR-based method called prime editing to introduce short 'landing pad' sequences that selectively recruit enzymes that in turn can precisely splice large DNA fragments into the genome. In 2022, for instance, genome engineers Omar Abudayyeh and Jonathan Gootenberg at the Massachusetts Institute of Technology, Cambridge and their colleagues first described programmable addition through site-specific targeting ele- ments (PASTE), a method that can precisely insert up to 36 kilobases of DNA8. PASTE is especially promising for ex vivo modification of cultured, patient-derived cells, says Cong, and the underlying prime-editing technology is already on track for clinical studies. But for in vivo modification of human cells, SSAP might offer a more compact  solution: the bulkier PASTE machinery requires three separate viral vectors for delivery, which could undermine editing efficiency relative to the two-compo-nent SSAP system. That said, even relatively inefficient gene-replacement strategies could be sufficient to mitigate the effects of many genetic diseases.\nAnd such methods are not just relevant to human health.\nResearchers led by Caixia Gao at the Chinese Academy of Sciences in Beijing developed PrimeRoot, a method that uses prime editing to introduce specific tar- get sites that enzymes can use to insert up to 20 kilobases of DNA in both rice and maize. Gao thinks that the technique could be broadly use- ful for endowing crops with disease and patho- gen resistance, continuing a wave of innovation in CRISPR-based plant genome engineering. \"I believe that this technology can be applied in any plant species,\" she says.",
