How childhood stress can undermine memory skills
Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Researchers have found that childhood stress can affect memory skill of students.

Many children today transition from playfulness and innocence to mental stress and other worries during adolescence. It is crucial to understand children’s issues and actively seek solutions rather than fretting over them. These challenges during a critical stage of development can significantly impact children’s memory and intelligence.
A world full of happiness and no worries… Such is the view of parents and guardians about the world of children. They don’t have to worry about work to be done or responsibilities, so what’s the stress on them? But the data coming out about children’s mental health suggests that these are all just our misconceptions.
The number of children seeking counseling and mental health treatment is increasing day by day. To those who wonder what tension they have for this alone, they say, many. At a very young age, children experience minor stress or mental tension!
What is stress?
What is stress if it affects even children? Stress is the body’s coping mechanism to deal with and adapt to challenging situations. A balance of demands from multiple sources or the ability to meet them leads to stress. Such demands may come from family, work, school, or friends, and sometimes one’s own demands can also lead to stress. Stress occurs when the demand and the ability to meet it do not match.
Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far
Stress occurs in children for many reasons. The worry of missing parents at a very young age, academic issues later in life, social pressures, mental and physical abuse, problems between parents and isolation all contribute to stress in children. Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far. Recently Indian researchers have found that childhood stress can affect memory skill of students.
Research conducted by a team consisting of Radha Raghuraman, Anoop Manakadan, Gal Richer Levin, and Sreedharan Sajikumar, in 2022, found that childhood stress can have a detrimental effect on memory.
How to spot stress in children
Stress and related problems in children can be difficult to identify, but sudden anger, mood swings, misbehaviour, changes in sleep patterns, and bedwetting can all be considered signs of stress. Some may also experience physical effects due to stress. For example, stomach ache and headache. Others have symptoms such as lack of concentration and inability to complete studies. Apart from this, being away from everyone and spending a lot of time alone is a sign of stress. Signs of stress include thumb-slapping, hair-twisting, nose-picking in young children, and lying, bullying, and backbiting in adults. Stressed out children can get into big fights even over small things. Falling behind in studies is also a symptom of stress.

The connection between stress and memory
Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Children are greatly influenced by the expectations placed on them by the adults around them, especially parents and teachers. Children often judge themselves by those expectations. When those expectations are not met or when their skills, abilities, and pride are called into question, they are unable to cope.
Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress
Recent studies have shown that stress levels in children have been on the rise over the past few decades. Radha Raghuraman says that exposure to stress during childhood can affect the ability to connect different types of memories as adults. The research team conducted studies on this in mice. As the juvenile phase in mice is equivalent to the adolescent phase in humans, adolescent stress is the main concern here. Radha explains that since the structures of the memory-related brain regions of mice and humans are almost identical, their findings may hold true for humans as well.

Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress. Depending on the age at which stress occurs, how long it has lasted, the intensity, and the type of stress, the changes it causes in the body and behaviour will vary.
Adolescent stress stimulates certain epigenetic factors. Like a gene, a piece of DNA that carries information necessary for specific functions in a cell, an epi-gene is a factor that causes a gene to decide whether or not to express the information in the gene, and if so, how much to express.
Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.
Through their study, Radha and his team found that stress during adolescence results in increased activation of the epi-gene G9a/GLP. It affects the formation of certain proteins that stabilise newly formed memories. As a result, memories that have already been formed are perfected and as they grow, there is no room for other memories that come in connection with them. Associative memory is the ability to connect existing memories with recent or recent events and find similarities and dissimilarities between them. Adolescent stress mainly affects associative memory. Radha says that G9a/GLP was found to be significantly higher in stressed mice. The researchers also found that associative memory was restored when G9a/GLP was blocked with the drug.
How to save children from stress
Adequate rest, nutritious food, closeness, attention and care of parents can give children a lot of relief from stress. Parents should try to be with their children when they want. If you notice that there are any problems, talk to them openly instead of thinking that they will tell you here.

Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.
Studies remind us that stress during adolescence should be viewed more cautiously than stress at any other time. Adolescence is also a period of growth in children. Facing stress at a time when the development of many important organs including the brain is not complete can lead to many types of consequences while growing up.

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.”
Musk made a statement there that sparked controversy. “They were left up there for political reasons.”
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.”
“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.
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.
