History News ,India :- Dr. George Gheverghese Joseph from The University of Manchester has uncovered groundbreaking revelations about the 'Kerala School' and their contributions to mathematics. He points out that the 'infinite series,' a fundamental concept in calculus, was actually identified by the Kerala School around 1350. Surprisingly, this discovery, which predates Sir Isaac Newton and Gottfried Leibnitz by centuries, has often been mistakenly attributed to them.Researchers from The Universities of Manchester and Exeter further reveal that the Kerala School also pioneered the Pi series and utilized it to calculate Pi with remarkable accuracy—up to 17 decimal places.Moreover, there's compelling evidence suggesting that Indian mathematicians shared their discoveries with Jesuit missionaries during the fifteenth century, potentially influencing the development of mathematical thought in Europe.Dr. Joseph emphasizes that while Newton's contributions to calculus remain significant, figures like Madhava and Nilakantha from the Kerala School deserve equal recognition for their discovery of infinite series, a vital component of calculus.However, the neglect of scientific achievements from non-European regions, influenced by historical biases stemming from colonialism, has obscured the Kerala School's contributions. Additionally, the lack of familiarity with the medieval form of Malayalam, the local language of Kerala, where much of the significant mathematical texts were written, has contributed to this oversight.Dr. Joseph also highlights disparities in the standards of evidence required to acknowledge knowledge transmission from East to West compared to the reverse. He suggests that the West's reliance on knowledge exchange from India and the Islamic world during the medieval period is well-documented, yet the contributions from these regions are often undervalued.He points out instances where European Jesuits, with expertise in mathematics and local languages, interacted with Kerala mathematicians, indicating potential knowledge transfer. For example, Pope Gregory XIII's committee, which included mathematician Clavius, sought information on calendar construction from diverse regions, with the Kerala School being a notable resource.Similarly, advancements in navigation during the Age of Exploration spurred the demand for accurate astronomical calculations, an area where Kerala mathematicians excelled.In light of these findings, it's essential to recognize the significant contributions of the Kerala School to the development of mathematics, bridging the gap in our understanding of its global history.Erratum: The University of Manchester acknowledges the significant work of Professor CK Raju in exploring the transmission of Kerala Mathematics to Europe, which should have been recognized in the original news release.

Science News ,World :- In an exciting development, doctors have successfully transplanted a pig kidney into a person for the first time. This success has researchers hopeful about using animal organs for human transplants, a process called xenotransplantation.The patient who received the pig kidney is Richard Slayman, a 62-year-old man suffering from severe kidney failure. He underwent surgery on March 16 and is recovering well, according to his doctors.The kidney came from a special miniature pig that had undergone 69 genetic changes. These changes were made to prevent rejection of the organ by the recipient's body and to lower the risk of any viruses that the organ might carry.Experts say that, at least in the short term, these transplanted pig organs are safe and work just like human kidneys. Luhan Yang, the CEO of Qihan Biotech in China, and a founder of the company that created the genetically modified pigs, eGenesis in Massachusetts, believes this case shows promising results.The company is now talking with the US Food and Drug Administration (FDA) about planning larger clinical trials. These trials would involve transplanting pig kidneys, hearts for children, and livers that would be connected to the recipient's body externally. Wenning Qin, a molecular biologist at eGenesis, confirms this plan.Hope for Saving Lives: Push for Full-Scale Tests of Animal Organ TransplantsIn the United States, when someone's life is in danger and there's no other way to help them, doctors sometimes use animal organs for transplants. This is called "compassionate use." Now, there's hope that these transplants might become more common.One person who had an animal organ transplant, named Slayman, got approval from the FDA for this special treatment. But Dr. Yang believes that with new positive results, the FDA might allow larger tests with more people. He thinks these transplants could give patients and their families hope and save lives.Using animal organs for transplants could also help solve a big problem: not having enough human organs for everyone who needs them. In the United States alone, nearly 90,000 people are waiting for a kidney transplant. Sadly, over 3,000 people die each year while waiting. Dr. Wayne Hawthorne from the University of Sydney in Australia says that even though more people are donating organs, there's still a huge shortage.Dr. Muhammad Mohiuddin, a surgeon and researcher, is excited about the possibility of more tests. He led the first transplant of a pig's heart into a living person. Dr. Mohiuddin, who also heads the International Xenotransplantation Association, believes that these tests can give us important information about how safe and effective animal organ transplants are.Before, surgeons have already put gene-edited pig hearts into two living people. They've also transplanted modified pig kidneys into people who were declared dead because their brains stopped working. Just recently, surgeons in China put a modified pig liver into a person who was clinically dead and kept it there for ten days. This shows that animal organ transplants might offer hope for many people in need.Dozens of EditsThe surgery to give Slayman a pig kidney lasted four hours, according to Tatsuo Kawai, one of the doctors who did the surgery. Slayman already had a human kidney that someone donated to him in 2018, but it was starting to fail. Because of this, Slayman had to regularly go for dialysis treatment. But he faced more problems and had to visit the hospital often, so doctors thought he could try getting a pig kidney.The pig's kidney given to Slayman had been changed by scientists at a company called eGenesis using a method called CRISPR–Cas9 genome editing. They changed 69 genes in the pig. Monkeys who got pig organs from this company with these changes in their genes lived for months to years. Qin, one of the scientists, believes Slayman's new pig kidney could last just as long, maybe even longer. This is because the changes were made with humans in mind, not monkeys.The changes included taking out three genes that help pigs make three types of sugars on their cells' surface. Our immune system sees these sugars as a sign of an enemy and attacks them. Seven new genes were added to make proteins like those in humans that help stop the body from rejecting the organ.Preventing Viral SpreadScientists have made 59 changes to the genes of pigs to stop viruses from becoming active in the human body. They worry that these viruses might become a problem once inside humans. While there haven't been cases of this happening in living humans or non-human primates who received pig transplants, lab experiments have shown that these viruses can move from pig tissues to human cells and to mice with weak immune systems.The first pig heart that was successfully transplanted into a person had a hidden virus, which might have caused the organ to fail eventually. Before approving such operations, the FDA is concerned about the risk of pig diseases spreading to the recipient. eGenesis regularly tests its pigs for pathogens like porcine cytomegalovirus, which can hide in pigs without causing symptoms.Before the transplant, researchers froze blood samples from the patient, his family, and his surgeons. If the patient gets sick later on, scientists can check these samples to see if they were the source of the illness.The patient will be regularly tested for diseases, and if he shows any symptoms, his family and caregivers will also be checked.These precautions are crucial because a pig might seem healthy, but its germs could still cause problems for someone with a weak immune system. Even if tests show no viruses or bacteria in the pigs before the transplant, there's still a risk they could grow and spread in a person with a compromised immune system. So, there are still many unknowns that scientists are trying to understand.Keeping Kidneys HealthyKidneys do a big job in our bodies. They clean out bad stuff, make pee, and help keep our blood pressure in check. When surgeons fixed up the blood flow to a transplanted pig kidney, it quickly turned pink and started making pee. That's a good sign the transplant worked.Doctors also look at something called creatinine in the blood to check kidney health. High levels of creatinine mean the kidney isn't doing its job of cleaning waste well. Before the transplant, Slayman had high creatinine levels, but by the fourth day after the surgery, it dropped a lot. Doctors hope it'll keep going down to a normal level."It seems like this kidney is working how it should," says Mohiuddin.Slayman might leave the hospital as soon as tomorrow. He's taking medicines to stop his body from rejecting the new kidney, and things are looking good so far. Scientists hope to tweak pig genes so recipients won't need these medicines, which can weaken the body."Before, people said pig organ transplants were a dream. Now, we have someone with a pig kidney—it's amazing!" says Qin.

Defense News ,Israel :- The soldiers from Israel who are fighting in Gaza have a special tool called the "Rooster." This tool helps them explore the underground tunnels that the Hamas group built under Gaza.The "Rooster" is made by a company called Robotican, which is from Israel. This company makes drones and robots.The Israeli soldiers, known as the Israeli Defence Forces (IDF), use the "Rooster" drone to explore the tunnels under Gaza. These tunnels make up a huge underground network, about 500 kilometers long, which Hamas built.The "Rooster" drone is not just used in Gaza. Military groups around the world also use it. It is designed for special units and commando teams for missions where they need to gather information, keep watch, and fight tactically.Robotican, the company that makes the "Rooster," says it's different from other drones. It's special because it can do two things: fly in the air like a normal drone and also move on the ground like a robot. This makes it really useful for exploring underground places.The company says the "Rooster" is a big improvement in how soldiers can gather information, stay safe, and do their job well. It was made especially for soldiers who fight in difficult places and have special tasks to do.The "Rooster" can work for up to ninety minutes at a time. When it's flying, it can stay in the air for about fifteen minutes, and when it's rolling on the ground, it can go for about forty minutes. It's made to be able to switch between flying and rolling easily, which means it can go anywhere, no matter the terrain.This special drone is really good at moving around. It can roll over rough ground and fly over things in its way, like windows or furniture. And it's built to be strong, with a cage around it to protect it from getting damaged if it bumps into things while flying.Soldiers can add different tools to the "Rooster" depending on what they need for their mission. They can attach things like sensors to measure things like radiation, gas, or temperature. This helps them gather information and stay safe while they're doing their important work.

Defense News ,India :- In good news for India's army upgrade plans, a lab called the Armament Research and Development Establishment (ARDE), which is part of the Defence Research and Development Organization (DRDO), is working on a lighter version of a powerful artillery gun called the Advanced Towed Artillery Gun System (ATAGS).This new gun is a smaller version of the 155mm/52 calibre howitzer and is made specifically to meet the Indian Army's needs. They want a next-generation Towed Gun System (TGS) that weighs less than 15 tons.The original ATAGS is already known for its strength and performance on the battlefield, but it's quite heavy, about 18 tons. To make it easier to move around and deploy, DRDO is creating this lighter version, which will still pack a punch but will be easier to transport.The goal is to keep the powerful features of the ATAGS while making it more advanced with new technology. DRDO wants to make sure it fits perfectly with the Indian Army's requirement to move quickly across different types of land.The Indian Army has ordered 400 of these new Towed Gun Systems to upgrade its artillery forces and deal with new security challenges. Even though they're also getting 307 of the heavier ATAGS, they need the lighter version to meet their requirements and plan for the future.There could be a big demand for these Towed Gun Systems, possibly up to 1200 units, which is great news for India's defense industry.This lighter ATAGS will be up against other similar guns, like the Adani-Elbit ATMOS howitzers. It's crucial for India to have the most advanced technology in its defense, especially in the competitive world of defense deals.
