How a CIA operation stopped Pakistanis from getting vaccinated against polio
Pakistan has fought hard against polio, slashing cases by over 99 per cent, according to Federal Health Minister Syed Mustafa Kamal. Decades of door-to-door vaccination drives, brave health workers, and global support have pushed the virus to the brink of extinction. But the fight isn't just against a disease. It's against poverty, conflict, and a lingering wound inflicted by a CIA operation more than a decade ago.
In 2011, a shocking secret came to light: the CIA had used a fake vaccination campaign in Abbottabad, Pakistan, to hunt for Osama bin Laden. It was a move no one saw coming, and its fallout would ripple for years. Reports from The Guardian and The New York Times revealed that the CIA, desperate to confirm if bin Laden was hiding in a local compound, enlisted a Pakistani doctor named Shakil Afridi.
His job? Run a pretend hepatitis B vaccination drive for kids in the area. But the needles weren't just for vaccines—they were a cover to collect DNA samples, likely through blood or saliva, from children near the compound. The hope was to match the samples to DNA from bin Laden's sister, who'd died in the US the year before, to prove if her brother—the elusive 'Pacer' the CIA was tracking—was really there.
The mission worked; Bin Laden was killed. But America's success came at Pakistan's cost.
Once news spread of the fake vaccination campaign, the backlash was swift and far-reaching. Many Pakistanis saw the episode as confirmation of their worst suspicions: that Western aid programs could be Trojan horses for intelligence operations. Public trust in vaccination campaigns, already fragile in parts of the country due to conspiracy theories and religious opposition, was severely damaged.
'Release of this information has had a disastrous effect on worldwide eradication of infectious diseases, especially polio,' The Lancet later reported.
Militant groups used the episode to reinforce conspiracy theories that vaccinations were a Western plot. In the years since, polio workers have been targeted by extremists, forced to operate under armed escort.
In Balochistan last November, a bomb tore through a police escort for vaccinators, killing nine, including five children. In Khyber Pakhtunkhwa, 20 health workers and guards have been killed in similar attacks. The violence forced groups like the UN to pause vaccination efforts, leaving millions of children unprotected.
As the violence increased, so did mistrust. According to Dawn, Pakistan's leading English daily, the numbers from recent immunisation drives are staggering. 'Khyber Pakhtunkhwa reported 19,070 refusals against oral polio vaccine in February,' the paper reported. Additionally, nearly 100,000 children were simply not home when health workers came – possibly because parents intentionally kept them away.
A study by researchers Monica Martinez-Bravo and Andreas Stegmann showed how the CIA's ruse gutted vaccination rates. In areas with strong support for extremist groups, vaccinations for polio dropped 28 percent, measles 39 per cent, and other diseases 23 per cent following the revelations. In some Taliban-controlled regions, vaccines were banned outright. The CIA's promise in 2014 to never again use health programs for spying came too late. The damage was done.
Vaccination refusal became ideological.
This growing mistrust has left the last mile of eradication out of reach. Meanwhile, attacks on health workers have become routine. Fear stalks every door-to-door visit. Paranoia thrives in the absence of trust. And a virus that should have been confined to history now clings to life—in part because public health was once used as a weapon of war.

UGC bans open and distance learning in healthcare, allied courses from current academic year
MUMBAI: The University Grants Commission (UGC) has directed all higher education institutions (HEIs) to stop offering programmes in healthcare and allied disciplines through Open and Distance Learning (ODL) or online mode from the July-August 2025 academic session. The order follows the recommendations of the 24th Distance Education Bureau Working Group meeting that was held on April 22 this year and was approved at the UGC's 592nd meeting on July 23. Representative pic (Getty Images/iStockphoto) The ban applies to courses under the National Commission for Allied and Healthcare Professions (NCAHP) Act, 2021. These include Psychology, Microbiology, Food and Nutrition Science, Biotechnology, Clinical Nutrition and Dietetics. According to the circular, institutions that already have the recognition to run these programmes will see it withdrawn by UGC. Colleges and universities have also been instructed not to admit students to such programmes from the 2025-26 academic session onwards. In cases where a programme offers multiple specialisations, such as a bachelor's degree in arts with majors in English, Hindi, History, Political Science, Philosophy, Sociology or Psychology, only the healthcare-related specialisation will be discontinued. Other non-healthcare subjects under the same degree will remain unaffected. The decision comes amid concerns over quality standards in professional training. Former Professor and head of the Psychology Department of the University of Mumbai, Satishchandra, said, 'The demand for psychology has gone up in recent years, leading to many private and public institutions offering it. But in several parts of the country, they have failed to maintain the quality of education. This decision will help check such practices.' Supporting the move, Vivek Belhekar, head of the Psychology Department at the MU, said, 'This is a welcome step that will benefit society at large. Clinical psychology requires rigorous practical training. As per the guidelines of the Rehabilitation Council of India, we need a 2:1 student-teacher ratio. Such training is not possible in the distance learning mode.' However, he also pointed to the challenge of limited seats available across the country. 'Considering the rising demand for clinical psychology, the UGC or the apex body must come up with a solution that allows public universities to expand opportunities, possibly through a structured online model,' he added.

How scientists built a password-protected mind-reading brain implant
Scientists have developed a brain-computer interface (BCI) — a device that allows the human brain to communicate with external software or hardware — which works only when the user thinks of a preset password. The findings were detailed in a study, 'Inner speech in motor cortex and implications for speech neuroprostheses', published in the journal Cell on August 14. The new system was developed by researchers based at Stanford University (the United States). Here is a look at how scientists built a password-protected BCI. But first, why are brain-computer interfaces significant? BCIs allow the user to control an application or a device using only their mind. Usually, when someone wants to interact with an application — let's say, they want to switch on a lamp — they first have to decide what they want to do, then they coordinate and use the muscles in their arms, legs or feet to perform the action — like pressing the lamp's on/off switch with their fingers. Then, the device — in this case, the lamp — responds to the action. What BCIs do is help skip the second step of coordinating and using the muscles to perform an action. Instead, they use a computer to identify the desired action and then control the device directly. This is the reason why BCIs have emerged as promising tools for people with severe physical disabilities. They are also being used to restore speech in people who have limited reliable control over their muscles. How was a password-protected BCI developed? The researchers involved in the study focused on 'internal-speech' BCIs, which translate brain signals into text or audio. While these types of devices do not require users to speak out loud, there is always a risk that they could accidentally decode sentences users never intended to say. To resolve this issue, the researchers first 'analysed brain signals collected by microelectrodes placed in the motor cortex — the region involved in voluntary movements — of four participants,' according to a report by the journal Nature. All of these participants had trouble speaking and were asked to either try to say a set of words or imagine saying them. The researchers then analysed the recordings of participants' brain activity. This helped them discover that attempted and internal speech originated in the same brain region and generated similar neural signals, but those associated with internal speech were weaker. This data was used to train artificial intelligence models, which helped BCIs to interpret sentences imagined by the participants after they were asked to think of specific phrases. The devices correctly interpreted 74% of the imagined sentences. To ensure that the BCIs do not decode sentences that users do not intend to utter, the researchers added a password to the system, allowing users to control when decoding began. 'When a participant imagined the password 'Chitty-Chitty-Bang-Bang' (the name of an English-language children's novel), the BCI recognised it with an accuracy of more than 98%,' the Nature report said.

New Study Could Boost IVF Success: 3D Video Shows How Embryos Implant
Scientists have recorded a real-time 3D video of a human embryo implanting into the uterus for the first time. They have used a synthetic uterus model to show how the process happens naturally in the body. The artificial embryos were donated by Dexeus University Hospital in Barcelona, and the research was done by the Institute for Bioengineering of Catalonia (IBEC). Researchers have analysed how the video of embryo implantation can help improve the success rates of fertility treatments such as IVF, reported The Guardian. Samuel Ojosnegros, principal investigator for the Bioengineering for Reproductive Health Group at the Institute for Bioengineering of Catalonia (IBEC) in Spain and study co-author, said, "We have observed that human embryos burrow into the uterus, exerting considerable force during the process." He called it a surprisingly invasive process. He said that when an embryo implants, it has to push into and merge with the tissue of the uterus to begin the pregnancy. Many women feel cramps or have light bleeding when it happens, but until now, nobody had seen the process, said Ojosnegros. According to Live Science, when implantation happens, the embryo sticks to the inner lining of the uterus and then starts growing by making more cells. He said that when implantation fails, the pregnancy cannot continue, and researchers say this is one of the biggest reasons for infertility. It is responsible for about 60 per cent of miscarriages. When a fertilised egg attaches to the uterine lining six to twelve days following ovulation, this is known as embryo implantation. Researcher Amelie Godeau told The Guardian, stated that the embryo pulls and reshapes the uterus lining while trying to implant. She said, "It also reacts to external force cues. We hypothesise that contractions occurring in vivo may influence embryo implantation." According to the study's findings, these contractions might be a crucial factor in a successful implantation. During the menstrual cycle, the type of spontaneous contractions that occur in the human uterus varies, often occurring one to two times per minute. The researchers said that this implies that there might be a frequency range that is ideal for embryo implantation.
