New blood type found: Woman in France is the only one to have 'Gwanda negative' blood group

Time of India4 days ago

A research has made a pathbreaking revelation to uncover the 48th
blood group system
after 15 years of investigation.
French scientists
made the new discovery after a blood sample collected for a routine pre-surgery test led hold something never seen before.
The new blood type has been named "Gwanda negative" because of its origin.
It began with a simple test
The pathway for the discovery began in 2011 when a 54-year-old woman in Paris, originally from a French Caribbean island Guadeloupe, underwent a basic pre-surgical blood test. However, her sample raised a red flag. It was not just about matching the usual blood groups but it also it carried an antibody that didn't fit into any known pattern.
Doctors noticed the strange anomaly, but back then, tools were not as powerful to decode the mystery. The sample was preserved. And for the next eight years, the case remained unsolved.
DNA sequencing unlocked the truth
Post the advancement in high-throughput DNA sequencing, scientists got back to the rare blood sample in 2019. This time, they found the clue they had been looking or.
Live Events
A genetic completely new genetic mutation was identified. This had never been observed before in the global blood group database.
The mutation was inherited by the woman from both her parents, meaning she had got a rare version of gene from each of them. It was this double inheritance that gave her a unique blood type, one that doesn't match with any known donor in the world. She is the only person on Earth, so far, who can safely receive her own blood.
The name
Gwada negative
was chosen not just because it reflects her roots in Guadeloupe, but also because it has a globally friendly sound that scientists believe fits its rare significance.
Why is this discovery significant
The major discovery might seem to be like a general isolated scientific event. However, this opens up crucial conversations in
blood transfusion
science.
When someone with an unknown or
rare blood type
needs surgery, blood transfusion becomes life-threatening if not matched correctly.
In severe cases, transfusion with an incompatible type can trigger severe immune reactions. This is the reason new blood group systems are important. They can explain previously unexplained medical emergencies and help researchers refine transfusion protocols, especially for people from diverse genetic backgrounds.
This is not just about cataloguing blood, it is about improving survival chances for people with rare blood types who may not even know they are rare.

Ada Lovelace: the Enchantress of Numbers

Women in STEM is a popular term you would have heard, and it is well-celebrated in the modern age. However, what about the women who laid the stepping stones for the term? Women who not only broke gender barriers but also played an important role in laying the foundation in several modern fields. One such icon was Ada Lovelace. Augusta Ada King, Countess of Lovelace, more commonly known as Ada Lovelace, was the daughter of the poet Lord Byron and his wife, Anne Isabella Milbanke. She did something most women deemed impossible then. She became the world's first computer programmer. Even though recognised much later, her visionary notes on Charles Babbage's Analytical Engine included what is recognised as the first computer algorithm, earning her that title. A mother's fear Being a single mother, Lady Byron was sceptical of several skills thought to be irrational — specifically subjects like the arts — which she associated with Lord Byron. In order to prevent Ada from having any poetic tendencies, Lady Byron made sure that her daughter received a rigorous education in science and mathematics, which were very uncommon for girls in her era. Ada had a natural aptitude for numbers and reasoning from a young age. Among her tutors were renowned mathematicians like Augustus De Morgan, a well-known logician, and Mary Somerville, one of the first female members of the Royal Astronomical Society. Ada's life changed dramatically when she met Charles Babbage, the inventor and mathematician who is frequently referred to as the 'father of the computer', when she was just 17 years old. Babbage was then developing the Difference Engine, a mechanical device used to perform mathematical calculations. Ada was fascinated by his ideas and demonstrated a thorough understanding of his work. They developed a strong intellectual bond, and Babbage was impressed by her perceptions and critical abilities. He affectionately referred to her as 'The Enchantress of Numbers'. Babbage and Lovelace's friendship and collaboration would become one of the most significant intellectual partnerships of the 19th Century. Babbage later started working on the Analytical Engine, a general-purpose computing machine. It contained many features that we see and use in modern computers, including an arithmetic logic unit and integrated memory. The path changer In 1842, based on a lecture Babbage gave in Turin, Italian engineer Luigi Federico Menabrea wrote a paper in French about the Analytical Engine. Lovelace was commissioned to translate this paper into English. But she went far beyond a mere translation. Her notes were three times longer than the original text and offered profound insights into the potential of the machine. She described how the engine could be programmed to perform tasks beyond pure number-crunching—such as composing music—highlighting her prescient understanding of computing as a universal machine. Lovelace most famously included a technique for using the Analytical Engine to calculate a series of Bernoulli numbers. This is widely regarded as the first algorithm ever intended to be executed by a machine, making her the first computer programmer in history. Did you know? Ada Lovelace Day, celebrated annually in October, promotes the achievements of women in science, technology, engineering, and mathematics (STEM). The U.S. Department of Defence named a programming language 'Ada' in her honour in the 1980s. She was also aware of machines' limitations and emphasised the difference between human creativity and machine processing, which is still relevant in discussions about automation and artificial intelligence today. But in the late 1840s, her health began to decline, and in 1852, she passed away from uterine cancer. She was buried next to her father, Lord Byron, in Nottinghamshire's Church of St Mary Magdalene, as she requested. For many years after her death, Ada Lovelace's contributions were largely forgotten. It wasn't until the mid-20th Century, with the rise of computer science as a discipline, that her work was rediscovered and properly recognised. In a field where women have been traditionally discriminated against and not taken seriously, Ada Lovelace shines bright as a pioneer in not just STEM but also feminism!

Nearly 12 million Americans to lose health coverage under Trump's budget bill, CBO warns

Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The sweeping budget bill backed by President Donald Trump and Senate Republicans is projected to strip health insurance from nearly 12 million Americans over the next decade, according to a nonpartisan Congressional Budget Office (CBO) analysis released Saturday bill, which narrowly advanced in the Senate with a 51-49 vote, would enact historic cuts to Medicaid and scale back key provisions of the Affordable Care Act (ACA), marking the most dramatic rollback of federal health coverage in modern U.S. CBO estimates that 11.8 million people would become uninsured by 2034 if the Senate's version of the bill becomes law—nearly one million more than projected under the House's version. The legislation calls for more than $1.1 trillion in cuts to Medicaid, Medicare, and Obamacare over the next decade, with Medicaid alone accounting for over $1 trillion of those reductions. These cuts would hit low-income families, children, seniors, and people with disabilities the hardest, as Medicaid currently covers over 71 million bill introduces strict new work requirements for many adults on Medicaid, including parents of children as young as 14, and imposes new co-payments for Medicaid services. It also reduces federal support for Medicaid expansion and alters tax credits that help millions afford ACA plans, changes that experts warn will disproportionately impact the South and West, where uninsured rates are already highest. According to Aaron Carroll, president and CEO of a major health policy group, 'The effects could be catastrophic,' with many forced to pay out-of-pocket for care, delay treatment, or lose access to essential proposed cuts have sparked deep divisions within the Republican Party . While fiscal conservatives push for deeper reductions, others—like Senator Thom Tillis of North Carolina, who announced he would not seek re-election after opposing the bill—have voiced concerns about the impact on their constituents and local hospitals. Democrats have uniformly opposed the measure, using Senate rules to delay a final vote and warning of the bill's consequences for American families.

France implements smoking ban at beaches and parks — Check details

France on Sunday banned smoking in public areas such as parks and beaches, aiming to protect the crowd from passive smoke and create the country's first non-smoking generation. The ban also applies to bus shelters and areas near libraries, swimming pools and schools, AFP reported. The initiative was introduced one week before the start of school holidays in order to shield children from smoke on beaches. However, the rules do not apply to all public spaces, which includes bar and restaurant terraces. The rule also does not apply to electronic cigarettes. "Frankly, I think it's ridiculous. We bring our own ashtrays and we're no longer allowed to smoke in parks, on beaches and so on," said Damien Dupois, a smoker. On the other hand, Romain Boonaert, a non-smoker enjoying the beach in La Porge outside Bordeaux, welcomed the move. 'There's plenty of space, but it's never pleasant when you get a little smoke on you. And then some people smoke other things too, so at least it takes away all the trouble.' According to the new rules, people should also not smoke within a 10 metres radius of schools, swimming pools, libraries and other places that can hurt minors. Those who violate the ban could face a fine of 135 euros ($160) up to a maximum of 700 euros. The punishment will be applicable after the initial grace period gets over. "Tobacco must disappear from places where there are children. A park, a beach, a school -- these are places to play, learn, and breathe. Not for smoking," Health and Family Minister Catherine Vautrin said. Vautrin said the ban was part of France's push for a "tobacco-free generation" by 2032. The ban "is a step in the right direction, but remains insufficient," said Yves Martinet, president of the National Committee Against Smoking (CNCT), criticising the continued permission to smoke on cafe terraces. "The minister points to the protection of children," but children "also go to the terraces," Martinet, a pulmonologist, said. Martinet also emphasised on the absence of e-cigarettes from the text, saying flavours are used to "hook young people". "For a measure to be effective, it must be clear — no consumption of products containing tobacco or nicotine in public," he said. However Frank Delvau, president of the Union of Hotel Trades and Industries (UMIH) for the Paris region had a different opinion about smoking on terraces. He said a ban on smoking on cafe terraces "would only shift the problem because people on terraces would smoke next to these establishments". Direct smoking is known to cause death, however as official data suggests, even passive smoking can be fatal as it causes anywhere between 3,000 and 5,000 deaths annually in France. Smoking causes 75,000 deaths a year and costs society 156 billion euros annually, the agency said. Smoking is steadily declining in France with "the lowest prevalence ever recorded since 2000", according to the French addiction agency OFDT. Less than a quarter of adults aged 18 to 75 smoked daily in 2023. A recent survey found 62% of French respondents support a smoking ban in public spaces, the news agency said.
