A new study involving nearly the entire adult population of England found that the incidence of heart attacks and strokes was lower after receiving the COVID-19 vaccination compared to before vaccination or without vaccination.

The study published in Nature Communications reported that the occurrence of arterial thromboses, including heart attacks and strokes, was up to 10% lower in the 13 to 24 weeks following the first dose of a COVID-19 vaccine. After the second dose, the incidence was reduced by up to 27% with the AstraZeneca vaccine and by up to 20% with the Pfizer/BioNTech vaccine.

The pattern of common venous thrombotic events, such as pulmonary embolism and deep venous thrombosis in the lower limbs, followed a consistent trajectory.

Research conducted by the Universities of Cambridge, Bristol, and Edinburgh, and supported by the British Heart Foundation (BHF) Data Science Centre at Health Data Research UK, analyzed de-identified health records from 46 million adults in England between 8 December 2020 and 23 January 2022. Data scientists compared the incidence of cardiovascular diseases following vaccination with the incidence before or without vaccination during the first two years of the vaccination program.

“We studied COVID-19 vaccines and cardiovascular disease in nearly 46 million adults in England and found a similar or lower incidence of common cardiovascular diseases, such as heart attacks and strokes, following each vaccination than before or without vaccination. This research further supports the large body of evidence on the safety of the COVID-19 vaccination programme, which has been shown to provide protection against severe COVID-19 and saved millions of lives worldwide,” Dr Samantha Ip, Research Associate at the Department of Public Health and Primary Care, University of Cambridge, said in a statement.

Previous research has found that the incidence of rare cardiovascular complications is higher after some COVID-19 vaccines. For instance, cases of myocarditis and pericarditis have been reported following mRNA-based vaccines like the Pfizer/BioNTech vaccine, and vaccine-induced thrombotic thrombocytopenia has been associated with adenovirus-based vaccines like the AstraZeneca vaccine. This study supports these findings but importantly did not identify any new adverse cardiovascular conditions linked to COVID-19 vaccination, providing further reassurance that the benefits of vaccination outweigh the risks.

The incidence of cardiovascular disease is higher after COVID-19, especially in severe cases. This may explain why the incidence of heart attacks and strokes is lower in vaccinated individuals compared to unvaccinated individuals, although further explanations are beyond the scope of this study, according to a press statement published by University of Cambridge.

New Research Could Allow People to Correct Robots’ Actions in Real-Time

Through basic interactions like pointing to the object, tracing a path on a screen, or physically nudging the robot’s arm, you could guide it to complete the task more accurately.

A breakthrough framework developed by researchers from MIT and NVIDIA may soon allow people to correct a robot’s actions in real-time using simple, intuitive feedback—similar to how they would guide another person.

Imagine you’re doing the dishes and a robot grabs a soapy bowl from the sink—but its gripper misses the mark. Instead of having to retrain the robot from scratch, a new method could enable you to fix its behaviour in real time. Through basic interactions like pointing to the object, tracing a path on a screen, or physically nudging the robot’s arm, you could guide it to complete the task more accurately.

This new approach eliminates the need for users to collect data and retrain the robot’s machine-learning model, unlike other traditional methods. Instead, it allows the robot to immediately adjust its actions based on user feedback to get as close as possible to fulfilling the user’s intent.

In tests, the framework’s success rate was 21 percent higher than an alternative method that did not leverage human corrections.

“This approach is designed to let robots perform tasks effectively right out of the box,” says Felix Yanwei Wang, an MIT graduate student in electrical engineering and computer science (EECS) and the lead author of a paper on the framework. “We can’t expect laypeople to gather data and fine-tune models. If a robot doesn’t work as expected, users should have an intuitive way to fix it.”

Wang’s co-authors include Lirui Wang PhD ’24, Yilun Du PhD ’24, senior author Julie Shah, MIT professor of aeronautics and astronautics and director of the Interactive Robotics Group at CSAIL, along with Balakumar Sundaralingam, Xuning Yang, Yu-Wei Chao, Claudia Perez-D’Arpino PhD ’19, and Dieter Fox from NVIDIA. The research will be presented at the upcoming International Conference on Robots and Automation.

A New Approach to Robot Correction

Currently, many robots use generative AI models trained on vast amounts of data to perform tasks. These models can solve complex tasks but often struggle to adapt to real-world situations that differ from their training environment. For example, a robot might fail to pick up a box from a shelf if the shelf in the user’s home is arranged differently than in its training environment.

To address this, engineers often collect new data and retrain the model—a time-consuming and costly process. However, the new MIT-NVIDIA framework allows users to interact with the robot during deployment, correcting its behavior in real time without the need for retraining.

“We want users to guide the robot without causing mistakes that could misalign with their intent,” says Wang. “The goal is to provide feedback that adjusts the robot’s behavior in a way that is both valid and aligned with the user’s goals.”

The system offers three ways for users to provide feedback: they can point to the object they want the robot to interact with, trace a desired trajectory on a screen, or physically nudge the robot’s arm. Wang explains, “Physically nudging the robot is the most direct way to specify user intent without losing any of the information.”

Ensuring Valid Actions

To avoid the robot making invalid moves—like colliding with nearby objects—the researchers developed a sampling procedure. This technique ensures that the robot chooses actions that are both feasible and aligned with the user’s request.

“Rather than just imposing the user’s will, we allow the robot to take the user’s intent into account while ensuring the actions remain valid,” Wang says.

The researchers’ framework outperformed other methods during tests with a real robot arm in a toy kitchen. While the robot might not always complete tasks immediately, the system allows users to correct it on the spot, without waiting for it to finish and then provide new instructions.

The framework also has the potential to learn from user corrections. For instance, if a user nudges the robot to pick up the correct bowl, the robot could log this action and incorporate it into its future behavior, gradually improving over time.

“The key to continuous improvement is having a way for users to interact with the robot,” says Wang. “This method makes that possible.”

Looking ahead, the researchers aim to improve the speed of the sampling procedure and test the framework in new, more complex environments, paving the way for robots that are more adaptable to real-world scenarios.

Starliner crew challenge rhetoric, says they were never “stranded”

Sunita Williams and Barry Wilmore don’t require a “rescue mission.” The veteran astronauts challenged some misconceptions the public has had about their over-extended stay aboard the International Space Station (ISS), following the Boeing Starliner mishap last June.

Last year on June 5th, NASA astronauts Sunita Williams and Barry Wilmore were on a flight testing mission to dock a Boeing Starliner spaceraft to the International Space Station (ISS). Set to return just eight-days later, their mission met with an ill-fated death. A few thrusters failed, in addition to a helium leak onboard, rendered the Boeing Starliner spacecraft too unsafe for NASA’s liking. The agency’s stubborn refusal to let their astronauts be under harm’s way, meant the Starliner returned to earth later in September without its crew.

In the months passing since then, Williams and Wilmore never left the public gaze. Media headlines and TV news anchors have taken to report the event as a major predicament. This is despite the fact, that the astronauts were neither stranded, nor left alone. Williams and Wilmore weigh in on the issue recently during a live interaction with the media.

“Butch (Barry Wilmore) and I knew this was a test flight,” Sunita Williams said to CBS News. “We knew that we would probably find some things (wrong with Starliner) and we found some stuff, and so that was not a surprise.”

This is not to say the situation the duo found themselves in is unprecedented; for it is indeed unprecedented. When NASA had Boeing Starliner‘s software reconfigured and return to earth in one shape. NASA had the benefit of doubt, given their original assessment was made with the best possible evidence available at the time; and not to compromise upon crew safety. As of latest plans, Williams and Wilmore will return to earth by late-March 2025 at the earliest.

But the rhetoric has reinforced calls to put together a “rescue mission.” SpaceX CEO Elon Musk, who advises incumbent US President Donald Trump, claimed at a Fox News interview that his proposal to bring the astronauts back in September was rejected by the previous administration led by President Joe Biden. Musk made a statement there that sparked controversy. “They were left up there for political reasons.”

Narratives draw ire from the space community

Musk’s comments drew ire from other veteran astronauts. Andreas Mogensen, a former ISS commander during Expedition 70, reacted to Musk’s comment on X to say, “What a lie. And from someone who complains about lack of honesty from the mainstream media.” Musk responded in kind soon there after, aggressively standing his ground. However, the astronauts themselves found the claims unsubstantiated.

According to WCVB Boston, Barry Wilmore himself said, “I have not heard that … I’m not sure that could be the case based on what I know. We came up here with a plan to return, and the plan changed.” NASA themselves had issued a clarification in the aftermath of Musk’s own comments, claiming it had never received a direct proposal from SpaceX for any mission. Nor did they warrant such a “rescue mission”, as now President Trump has called on for.

Political considerations are not a factor in changing the timelines in the ISS expeditions. “The White House was very good about letting us make safety decisions and leaving that to the experts at NASA,” Bloomberg reported Pam Melroy, an ex-NASA administrator involved in the mission, as having said.

“Help us change the rhetoric …”

Risks and derailed plans are part and parcel of space travel, and something space agencies draw backup plans for. Much of the public angst and concern for the astronauts is the loneliness arising from prolonged isolation in space, and fears of mishap with the ISS.

“That is what the human space flight program is; it prepares for any and all contingencies that we can conceive of, and we prepare for those,” Newsweek reports Sunita Williams as having said. Health professionals on ground have helped monitor and manage their physical and psychological fitness. Inadvertently, they contribute to research studying the human body’s ability to adapt in the micro-gravity conditions; as well as psychological resilience and the astronauts’ ability to handle stress. But this is nothing astronauts cannot handle. In fact, Williams compared her situation with that of a tourist. “I call it a little vacation from earth.”

They have had astronauts from the Crew 8 expedition give them company during the arrival in June, assisting them with their microgravity-based scientific experiments. In September, they were joined by a new party of astronauts of the Crew 9 mission – Roscosmos’ Alexander Gubnov, and NASA’s Nick Hague replacing the astronauts from Crew 8.

In addition to extra clothing and stockpile of food, NASA had left two extra seats were left empty for Williams and Wilmore to return along with Gubnov and Hague on their return later this March or April, when astronauts from upcoming Crew 10 dock later this month. Given there is a spacecraft docked to the ISS at all time, they have all what it takes to evacuate during an emergency.

“So if you’ll help us change the rhetoric, help us change the narrative…let’s change it to ‘prepared and committed’ rather than what you’ve been hearing,” WCVB Boston reported Williams as having said.
