Suspected dinosaur DNA found, dinosaurs can be revived?
Don't bother, in fact it never disappears
Big news! Scientists have discovered well-preserved erythrocytes in 125 million-year-old fossil Sicilians in the Jehovah Iota, located in northeastern China. These cells also have thin filamentous chromatin preserved in their nuclei, which is the vehicle for preserving DNA.
The DNA fragment with genetic information at the same time stores all the information about the process of race, blood type, conception, growth, and apoptosis of life. This means that we can bring dinosaurs back to life with this. Doesn't that sound exciting? But the actual operation can be difficult, after all, this is not the first time dinosaur DNA has been found.
As early as the 1990s, scientists in China have been from a 65 million-year-old dinosaur egg fossil, the first time to obtain dinosaur gene fragments. But if you want to replicate the complete dinosaur, you have to get the complete genetic data. This DNA is more likely to be found in the "softer parts" of the animal, such as organs, blood vessels, nerves, muscles, and fat. But these soft parts are long gone, either decayed or eaten by another dinosaur.
Even the bones, after burial, decomposed and lost their organic material, which was then replaced by surrounding minerals and gradually citified. The clues left behind also tell us only about the shape and size of the specimen, how long it survived, and some of the animal's unique characteristics, but do not provide us with critical genetic information.
It has also been shown that DNA has a half-life of 521 years. That means that every 521 years, half of the chemical bonds between DNA molecules are broken. By analogy, year by year, it will eventually take only 6.8 million years for these chemical bonds to be destroyed by time to nothing. The rate of DNA breakdown must have been accelerated by heat, acidic conditions, and the release of DNA enzymes by microorganisms. However, the last dinosaur to die at the end of the Cretaceous would have been over 65 million years ago, and no DNA would have lasted that long. If that's the case, then why did we find dinosaur DNA this time?
As organisms are buried and citified, they often undergo replacement at the molecular level, such as simplification - where the carbonaceous matter inside is replaced with silica. In addition, common replacements include phosphorylation, prioritization, calcification, randomization, and so on. Fossils preserved by the replacement of minerals of different compositions have different degrees of refinement, with simplification being the highest.
Researchers from the Chinese Academy of Sciences extracted a cartilage sample from a piece of bone near the joint portion of the distal end of the femur of the Audiometer. After calcifying the bone and analyzing its micro-structure using microscopic imaging techniques, it was found that the cartilage cells of the dinosaur underwent simplification after death, which coincided with the preservation of the complete form of the cartilage cells.
The team then extracted some of the cells and used biochemical methods to stain them, revealing the nucleus and filamentous chromatin of one of the cartilage cells. This suggests that the organic material in the dinosaur skeleton was not completely "citified" and that at least the cartilage cells still contained the dinosaur's organic molecules.
But these are still just remnant DNA fragments, not enough to replicate the dinosaur. So we have no chance to revive dinosaurs? Don't be discouraged, there are many ways. Most people have heard the phrase: "The ancestor of chickens was Tyrannosaurus Rex," which is unexpected. The reality, however, is that the two do not have a direct heritage relationship, although they are indeed relatives. Because the ancestor of modern birds is a hand-robbing dinosaur, and the tyrannosaur family is a "cousin" relationship. Therefore, it can be said that they are the descendants of living dinosaurs. And scientists are planning to find some potential ancestral genes from the chicken, to create dinosaurs.
The ancestors of chickens (birds) go back further, to other dinosaurs. Until now, they share many features with their dinosaur ancestors, such as bipedal walking and the air-bag respiratory system. The difference lies in the fact that other dinosaurs had a backward center of gravity and birds had a forward center of gravity. This is because during the evolution from arthropods to arthropods, the long tail was gradually shortened and the caudal femoral length muscle was gradually reduced.
During the evolution from arthropods to birds, the tail shortened further and healed into a caudal helix, and the caudal long disappeared completely, while the forelimbs and pectoral muscles tended to develop, which led to a forward shift of the center of gravity when birds stood. Even now, we can still find ancient features such as the long tail in the early stages of chicken embryo development. Such an embryonic development process also gives science the confidence to replicate dinosaurs.
Scientists believe that figuring out why the tail went from long to short during development and reversing the process that formed the short tail would give them a chance to find the ancestral gene. This may sound very incredible, but in 2006, Matthew Harris and John Gallon proved that such experimenters, do not pipe dreams.
While studying mutant embryos of chickens, Matthew Harris found a specimen preserved in a formalin solution whose beak was surprisingly covered with many tiny teeth! Although it sounds like a joke, it is easy to understand when you think back to the origins of chickens, after all, they too were once the dominant species on earth.
To make sure this was not a joke, Matthew Harris added growth factors to a normal embryo to stimulate the production of a certain protein and to see if this would happen repeatedly. Not surprisingly, after the addition of the protein and growth factor, the chicken embryo grew tiny teeth similar to those of the crocodile embryo and the jaw was altered.
In addition to teeth, many experimental projects have studied one after on the face, arms, and paws. Scientists believe that once they finish studying all parts of the body, it is possible to create a dinosaur-like animal. Of course, it is unlikely that now, but over time, the small and tender chicken will one day be magically transformed back into a mighty dinosaur, and may be served on the table. If you really can not wait to try the taste of dinosaurs, then go to the kitchen to stew a chicken it!

What’s Your Reaction to the U.S. Military Operation in Venezuela?
Few foreign policy decisions in recent years have sparked as much global debate as the U.S. military operation in Venezuela. The dramatic intervention — which resulted in the capture of President Nicolás Maduro — has forced governments, analysts, and ordinary citizens alike to confront uncomfortable questions about sovereignty, legality, and the future of international order. Reactions have ranged from celebration to outrage, often shaped by political alignment, personal values, and historical memory. But beyond the headlines, the operation represents something deeper: a turning point in how power is exercised and justified in the modern world. A Shock That Traveled Worldwide The speed and scale of the operation stunned observers. In a matter of hours, a leader who had weathered years of sanctions, diplomatic isolation, and internal unrest was removed from power and placed in U.S. custody. For supporters of the move, it was decisive action against an authoritarian figure accused of corruption and criminal activity. For critics, it was a dangerous violation of international norms. What made the event especially jarring was its symbolism. The capture of a sitting president by a foreign military shattered long-standing assumptions about immunity and restraint. It signaled that Washington was willing to cross lines that had, for decades, remained largely theoretical. Inside the United States: Applause and Alarm At home, Americans have been deeply divided. Some praised the operation as long-overdue accountability for a leader blamed for Venezuela’s economic collapse and humanitarian crisis. To them, the mission demonstrated strength and resolve after years of what they see as ineffective sanctions and diplomacy. Others reacted with concern or outright opposition. Critics questioned whether the president had the legal authority to order such an operation without explicit congressional approval. Civil liberties advocates warned that bypassing democratic checks could erode constitutional norms and set a troubling precedent. For many Americans, the question wasn’t just whether Maduro deserved removal — but whether the United States should be the one deciding that fate through military force. Latin America’s Uneasy Response Across Latin America, the reaction was largely critical. The region carries deep historical scars from U.S. interventions, and for many governments, the operation revived fears of a return to gunboat diplomacy. Even countries that had previously criticized Maduro expressed discomfort with the method used. Leaders warned that while authoritarianism should be challenged, unilateral military action risks destabilizing the region, triggering refugee flows, and inflaming tensions. For Venezuelans themselves, reactions have been complex. Some welcomed Maduro’s fall with relief and hope, while others feared chaos, retaliation, or a prolonged power vacuum. Celebration and anxiety existed side by side. Global Powers and the Question of Precedent Major global powers were quick to weigh in. Critics framed the operation as a violation of international law and national sovereignty, arguing that it undermines the very rules designed to prevent global instability. Supporters countered that traditional norms have failed to hold criminal leaders accountable, and extraordinary cases require extraordinary measures. At the heart of the debate is precedent. If one powerful nation can remove a foreign leader by force, what stops others from doing the same? The concern is not only about Venezuela, but about a world where might increasingly defines right. This fear has resonated even among U.S. allies, many of whom worry about the erosion of a rules-based international system. Law, Morality, and Selective Justice One of the most heated aspects of the debate revolves around legality. Supporters argue that Maduro was not treated as a legitimate head of state, but as a criminal accused of transnational crimes. From this perspective, the operation resembles an aggressive law-enforcement action rather than an act of war. Opponents reject this framing. They argue that international law does not allow one state to unilaterally seize another country’s leader, regardless of allegations. They also question why similar standards are not applied consistently to other controversial leaders around the world. This perception of selective justice has fueled skepticism about Washington’s true motivations. Strategic Interests Beneath the Surface Beyond morality and legality, strategic calculations are impossible to ignore. Venezuela sits atop vast oil reserves and occupies a geopolitically sensitive position in the Western Hemisphere. For years, the country has also served as a foothold for rival powers seeking influence near U.S. borders. Supporters of the operation argue that removing Maduro weakens criminal networks, curbs rival influence, and opens the door to regional stability. Critics see a familiar pattern: humanitarian and legal arguments masking strategic and economic interests. The truth likely lies somewhere in between, adding to the controversy rather than resolving it. The Human Cost Often Overlooked Lost in much of the geopolitical debate is the human cost. Military operations, even targeted ones, rarely unfold without casualties or trauma. Venezuelan security forces, civilians, and even U.S. personnel were reportedly harmed during the operation. For ordinary Venezuelans, the future remains uncertain. Removing a leader does not automatically rebuild institutions, restore trust, or heal a fractured society. The risk of prolonged instability looms large. A Moment That Forces Reflection So what should our reaction be? For some, the operation represents justice finally catching up with impunity. For others, it is a troubling reminder of how quickly norms can be discarded when power allows. Most people likely feel a mix of emotions — relief at the end of an era in Venezuela, unease about the method used to achieve it. The U.S. military operation in Venezuela forces a difficult reckoning. It challenges assumptions about sovereignty, accountability, and the limits of power. It also highlights a growing tension in global politics: the frustration with slow, ineffective systems versus the risks of decisive, unilateral action. Conclusion: Strength or Slippery Slope? Whether history judges the operation as a bold stand for justice or a dangerous overreach will depend on what follows. If Venezuela moves toward stability, accountability, and self-determination, supporters will claim vindication. If chaos, resentment, and copycat interventions follow, critics’ warnings may prove prophetic. What’s clear is that this moment has reshaped the conversation about U.S. power and global order. And regardless of where one stands, it is a development no one can afford to ignore.
