In today's times, a huge number of people depend on blood transfusions.
Those that need it can range from accident victims to people with blood disorders like Thalassemia.
While these transfusions are a common practice in today's world, that was not the case in the 17th Century. Back then, it was unheard of.
But all changed when the first successful blood transfusion took place on June 15, 1667, in France.
French physician Jean-Baptiste Denys performed it to transfuse 0.35 litres of a lamb's blood into a 15 year-old-boy who had been severely weakened by a prolonged fever and repeated bloodletting.

On this day in 1917, the US Congress passed the Espionage Act, just two months after it formally entered World War I. 'All the President's Men', the first definitive book about the Watergate scandal, was published on this day in 1974.
Nearly two months later then-President Richard Nixon resigned from office.
The first blood transfusion was performed
One of the most pivotal moments in medical history took place on this day in 1667 when French physician Jean-Baptiste Denys performed what is widely considered the first fully documented blood transfusion to a human.
Faced with a 15-year-old boy suffering from a severe, two-month fever, Denys and his assistant first tried the traditional method of 'letting blood.' When this proved ineffective, they opted for an experimental blood transfusion from a live animal, a technique they had been exploring for years.
Connecting a tube from a lamb's artery to a vein in the boy's arm, they transferred approximately 340 grams of blood. After the procedure and a period of rest, Denis noted the boy awoke feeling 'cheerful enough' and subsequently made a full recovery.

Denys later performed another successful animal-to-human transfusion on a labourer. These early attempts at xenotransfusion (transfusing blood from one species to another) were experimental and often met with controversy and mixed results, with some subsequent patients experiencing severe reactions and even death. The scientific understanding of blood compatibility, including blood types, would not emerge for centuries.

Despite the inherent risks and the eventual ban on animal-to-human transfusions due to adverse reactions, Denys's courageous experiments on June 15, 1667, marked a crucial early step in the long and complex history of blood transfusion.
US Congress passes Espionage Act
A landmark federal law was enacted on June 15, 1917, with the US Congress passing the Espionage Act, just months after it officially entered World War I. The law was enacted in view of widespread concerns about national security, espionage and growing anti-war sentiment.
Under President Woodrow Wilson , Attorney General A. Mitchell Palmer was a key enforcer of the Espionage Act. This legislation effectively made it an offence to transmit information designed to hinder the US armed forces' conduct of the war or to promote the adversaries' cause.
Convicted individuals were liable to a $10,000 fine and 20 years in prison. Furthermore, it made it illegal to make false statements intended to interfere with military operations, cause insubordination, disloyalty, or obstruct military recruitment.
The Espionage Act was reinforced by the Sedition Act of the following year, which imposed similarly harsh penalties on anyone found guilty of making false statements that interfered with the prosecution of the war, insulting or abusing the US government, the flag, the Constitution or the military, agitating against the production of necessary war materials or advocating, teaching or defending any of these acts.

It is still relevant today. The Julian Assange case is one of the most recent cases where the Act has come into effect. In June 2024, Julian Assange, the founder of WikiLeaks, pleaded guilty to a single count of conspiracy to obtain and disclose national defence information, a violation of the Espionage Act.
'All the President's Men' was published
One of the most ground-breaking non-fiction books 'All the President's Men' was published on this day in 1974.
The book was a detailed account of the investigative reporting of the Watergate scandal. This release occurred just months before President Richard Nixon's resignation, making it an incredibly timely and impactful exposé on the unfolding Watergate scandal.
Authored by Bob Woodward and Carl Bernstein, the book told the behind-the-scenes story of the Watergate scandal beginning with the 1972 burglary of the Democratic headquarters at the Watergate Complex , and revealing the full scope of the saga.

It revealed the involvement of officials like HR Haldeman and John Ehrlichman and famously introduced the mysterious anonymous source, ' Deep Throat, ' whose identity remained a secret for over 30 years.

With this book, the authors became household names.
The Denver Post termed All the President's Men, 'One of the greatest detective stories ever told.' Time magazine called the book 'perhaps the most influential piece of journalism in history.' The New York Times dubbed it a 'fast-moving mystery, a whodunit written with ease.'

Sir Ronald Ross and the mosquito link: how one nobel winning discovery changed the course of malaria control
Before Sir Ronald Ross's discovery in 1897, malaria was understood to be a disease caused by bad air ('mal aria,' meaning bad air). While the disease was recognised and feared for centuries, the underlying cause was not known. Understanding how malaria spreads: A scientific turning point On August 20, 1897, while working in Secunderabad, India, Ross dissected a mosquito that had fed on a malaria-infected patient. Inside its gut lining, he observed the presence of Plasmodium parasites—the microscopic organisms responsible for malaria. This observation provided the medical community with the first solid evidence that mosquitoes act as carriers of the disease. Although French military doctor Charles Laveran had identified Plasmodium in human blood in 1880, the method of transmission remained unclear. Ross, building on the ideas of physician Patrick Manson, confirmed that the malaria parasite requires a mosquito host to complete part of its life cycle before being passed to humans. Marking this discovery, Ross noted in his journal: 'This day relenting God Hath placed within my hand, A wondrous thing…' These words captured not only a breakthrough in understanding infectious disease but also a shift in how malaria prevention would be approached from then on. A scientific method grounded in observation and precision Ross conducted careful experiments using birds infected with Plasmodium relictum, an avian form of malaria. He allowed mosquitoes to feed on these birds and later dissected them at regular intervals. Over time, he found the parasites developing in the mosquito's stomach lining -- later forming what we now know as oocysts. This work revealed the external (or 'extrinsic') development of Plasmodium in the mosquito. Ross had traced the full transmission cycle, proving mosquitoes were not just incidental but a necessary host for the parasite. His work became the foundation of what we now call vector biology—the study of how insects and other organisms transmit diseases. The World Health Organization (WHO) acknowledges Ross's discovery as a pivotal moment in public health, reporting that it 'opened up a new vista for prevention and control of malaria' Changing how public health systems responded to malaria Ross's findings had a direct impact on how malaria was managed in India, Africa, and Southeast Asia. Once mosquitoes were identified as vectors, public health teams focused on controlling mosquito breeding: draining stagnant water, managing swamps, and later using insecticides like DDT. Ross went on to work in Sierra Leone and Mauritius, where he applied these principles in real-world malaria control efforts. He used mapping, statistics, and population data to track infection spread—techniques that are still used in disease surveillance today. In 1902, Ross received the Nobel Prize in Physiology or Medicine for his work. The citation read:'for his work on malaria, by which he has shown how it enters the organism and thereby has laid the foundation for successful research on this disease and methods of combating it.' His legacy Ross was also a prolific writer, poet, and advocate for medical education in the colonies. He pushed for more locally-run laboratories and for training Indian personnel in research methods, long before it became common practice. He also developed early mathematical models for how malaria spreads, laying the groundwork for what would become the Ross-Macdonald model—a widely used formula to estimate malaria transmission based on mosquito and human populations. The Centers for Disease Control and Prevention (CDC) notes that Ross's work, in collaboration with George Macdonald, led to the development of a mathematical model of mosquito-borne pathogen transmission . Over 125 years later, Ross's discovery continues to influence how we fight malaria. Vector control—like bed nets, mosquito repellents, and larvicide treatments—remains one of the most effective strategies to prevent the diseas .The WHO emphasises that controlling insect vectors has played an increasingly important role in reducing the burden of malaria since Ross's discovery . August 20 is now remembered as 'Mosquito Day' in his honor, especially in India. His field lab in Secunderabad has been turned into a memorial, and medical researchers still refer to his original drawings and writings. Sir Ronald Ross died in 1932. At the Liverpool School of Tropical Medicine, where he later taught, his epitaph reads: 'He gave to mankind an immense weapon against death.'

Trump administration hands over immigrant Medicaid data, targets 'unsatisfactory immigration status'; raises privacy law concerns
US President Donald Trump (Image credits: AP) The Trump administration this week gave deportation officials access to personal data, including immigration status, of millions of Medicaid enrollees, raising legal and ethical concerns within the government. Internal memos and emails revealed that officials at the Centers for Medicare and Medicaid Services (CMS) objected to the data transfer, arguing it could violate federal laws like the Social Security Act and the Privacy Act of 1974, AP reported. Despite their objections, two senior advisers to health secretary Robert F Kennedy Jr ordered the information be shared with the Department of Homeland Security (DHS). CMS was given just 54 minutes on Tuesday to comply. A spokesperson for the department of health and human services (HHS), Andrew Nixon, said the data sharing was legal and in line with federal regulations. He declined to explain why the data was shared or how DHS plans to use it. The data included names, addresses, Social Security numbers, and claimed information of people in California, Illinois, Washington state, and Washington, DC- states that allow non-citizens to receive state-funded Medicaid. The release came as immigration enforcement was increasing in Southern California. Experts said the information could be used to locate undocumented immigrants and potentially deny green cards, permanent residency, or citizenship to those who had received federally funded Medicaid benefits. California governor Gavin Newsom's office expressed concern over the move, calling it 'extremely concerning' and 'potentially unlawful.' The statement also criticised the use of personal information in federal immigration enforcement efforts. Last month, CMS announced a targeted review of Medicaid enrollees in certain states to ensure federal funds were not used for people with 'unsatisfactory immigration status.' The memo showed CMS officials tried to block DHS's request, saying that the data was meant only for administering Medicaid, not for immigration enforcement.
