Able-bodied people take many things for granted, whether it is their ability to function their limbs, hear or speak. These things make up for a huge part of one’s life and it is only when you lose it that you understand how valuable it was. Many people go through losing their voice or speech, it could be after a stroke, an accident or other health issues. Communicating with them after a traumatic event as such can be difficult and make them feel handicapped in many ways. So, what if we could hear them, without the extra effort, almost like looking into their minds?
Scientists have made a big leap forward by creating a brain implant that can turn a person's thoughts into spoken words. This special device isn't about mind-reading; it's the first of its kind that can actually "hear" and speak the words a person is only imagining in their head.
Developed by a team at Stanford University, this technology could be a huge help for people with severe paralysis who cannot speak on their own. For the very first time, researchers can understand what the brain is doing when someone is just thinking about speaking, offering a much more natural way for those with severe speech issues to communicate.
The study involved four individuals who had paralysis from conditions like ALS or a brainstem stroke. A device called BrainGate, which uses tiny sensors called electrode arrays, was implanted in their brains. Specifically, the implant was placed in the motor cortex, the area responsible for controlling speech. The participants were asked to either try to speak or simply imagine speaking certain words.
The device then picked up on the brain signals related to phonemes—the small, basic sounds that make up words (like the "c" sound in "cat" or the "a" sound). An advanced artificial intelligence (AI) program then took these brain signals and stitched them together to form full sentences.
The researchers found that even the signals from imagined speech were strong enough for the device to recognize words with up to 74% accuracy in real-time. This is a huge step forward because, as senior author Frank Willett explained, trying to speak for someone with paralysis can be exhausting and difficult. This new method could one day allow them to communicate fluently just by thinking.
The researchers explained how this tool could be very useful for people who have paralysis, as it would make communication easier. One of the biggest issues people with paralysis face is the change in communication style, and it has a huge impact on their daily life.
To understand how much impact it had a 2019 study published in the Disability and Rehabilitation journal looked at real life experiences of people with a neck-level spinal cord injury who did not use a ventilator. They were interviewed about how their communication changed and how it affected them.
This study explores what it's like to experience communication changes after a spinal cord injury in the neck. People shared how their voice and speech were different, the challenges they faced in being understood, and how these changes impacted their daily activities and social lives. The research shows that these communication issues have a wide-ranging effect, not just on a person's body but on their ability to interact with the world around them.
It would suffice to say that a device that could accurately communicate what they want could significantly impact their quality of life.
The research team also considered the important issue of privacy. They were surprised to find that the device could sometimes pick up on words the participants weren't trying to imagine, such as numbers they were silently counting. To solve this, they created a unique "password" system.
The device only starts decoding thoughts when the user consciously "unlocks" it. In the study, simply imagining the phrase "chitty chitty bang bang" worked almost perfectly—98% of the time—to prevent unintended decoding. This shows that the technology can be designed with user privacy and control in mind.
The researchers are very hopeful about the future of this technology. They believe it will one day restore communication for people with paralysis, allowing them to speak as easily and comfortably as a regular conversation. This new tool offers another option for individuals who rely on such devices, providing a path toward more fluent and natural communication.

You sneeze, and instead of a polite “bless you”, your bladder loses control. A laugh turns into a dribble. A cough? Well, tissues are not the only thing getting used. If this sounds familiar, you might be experiencing urinary incontinence. Nearly half of adult women go through it at some point. And while it is often whispered about in changing rooms or ignored altogether, it is a very real, very common problem.
Your bladder is not misbehaving for no reason. It is more like a balloon being held in place by a hammock of muscles called the pelvic floor. When that hammock loosens due to, say, pregnancy, childbirth, menopause, or years of constipation and coughing, the balloon slips, and leaks happen.
Some days it is a few drops; other days it feels like your bladder staged a prison break. Either way, it is exhausting and, for many women, embarrassing enough to change how they socialise, work out, or even laugh freely.

Beyond the soggy underwear situation, incontinence messes with how women feel about themselves. You might skip that morning jog, pass on road trips, or avoid wearing light-coloured trousers. Some even avoid intimacy out of fear. It is not just physical; it can nibble away at your social life and mental health too.
But you do not have to live like this. Your bladder may be out of control, but it should not control you.
Now for the part nobody tells you: fighting leaks can actually be oddly simple. And no, you do not need a gym membership, expensive gadgets, or chanting over herbal teas. You just need a pillow and a few minutes a day.
Imagine you are trying to stop urine mid-stream. That is the move. Hold for five seconds, release, and repeat. Nobody around you will even know you are doing it, which makes it the perfect exercise for office Zoom calls.

Beyond exercises, a few tiny tweaks can make a big difference:

After long work weeks, all we look forward to is a nice weekend, whether you like spending it relaxing or spending time with your friends. People use these days to catch up on different things, whether it is their time with their families, friends or overdue work. Since you do not have the pressure to wake up for work the next day, you have the luxury of staying awake for as long as you want. However, many people think this applies to their healthy habits as well. Eating healthily throughout the week so that they can eat junk at the end of it or sleep early every day so that you can stay awake. However, the 2-day de-stressor you take could be the reason why you reset all your progress to zero, especially those who have pre-existing conditions like sleep apnea.
For many, the weekend means going into social overdrive—but a recent study suggests this can come at a cost to your health. Researchers have found that the bad habits that often go with partying, like overeating, drinking, smoking, and staying up late, can worsen a serious condition called obstructive sleep apnea.
Obstructive sleep apnea is a disorder where a person's breathing repeatedly stops and starts while they sleep. This can lead to gasping for air and loud snoring. A new study published in the American Journal of Respiratory and Critical Care Medicine which was based on data from over 70,000 people across 23 countries, found that participants were 18% more likely to have moderate to severe sleep apnea on weekends compared to weekdays. Researchers are calling this phenomenon "social apnea."
The study also found that men were at a higher risk for this "social apnea" than women, and people under 60 were more affected than those over 60. The study suggests several reasons why our weekend routines can make sleep apnea worse.
On weekends, many people sleep in later and longer, which can shift their body clock. This is similar to the effects of jet lag and can increase the risk of worse sleep apnea. In fact, sleeping an extra 45 minutes or more on weekends raised the risk of severe sleep apnea by 47%.
Alcohol relaxes the throat muscles, making it easier for the airway to collapse and block breathing. It also makes it harder for the brain to wake a person up when breathing stops, so these events last longer. Smoking also makes the condition worse by causing swelling and inflammation in the airway.
Gaining weight from overeating on the weekends can put pressure on the throat and make it harder to breathe.
People often get more REM sleep on weekends, which is a deep sleep phase where throat muscles can become almost paralyzed, making the airway more likely to collapse.
Sleep apnea is a serious health condition that affects at least 30 million adults in the U.S. When breathing repeatedly stops and starts during sleep, it can lead to a variety of serious health risks, including:
To avoid the negative effects of "social apnea" on your health, experts recommend a few simple changes like keeping a consistent sleep schedule. Try to go to bed and wake up at similar times, even on the weekends. Try to limit alcohol and avoid smoking, especially on weekends. If you use a CPAP machine or another medical device for sleep apnea, make sure to use it every night, including on the weekends.
By being mindful of your weekend habits, you can improve your breathing and overall health without needing more medical help. If you have concerns about sleep apnea, you should talk to your doctor.
Microplastics have been a major cause of concern for many people. Not only have many people made the switch to paper straws, plates or glass bottles, but people are also changing what kind of packages enter their homes. However, was that enough? It may not have been.
Many of us assume that drinking from a glass bottle is better than a plastic one. However, a new study suggests this might not be true. The research found that some beverages in glass bottles actually have more microplastics—tiny plastic particles—than those in plastic bottles or cans. Scientists believe the caps on the glass bottles may be the main reason for this surprising finding.
Microplastics are everywhere: in our oceans, soil, air, and even our bodies. They have been linked to health problems like infertility, hormone issues, and even cancer. This study challenges the idea that glass is automatically the safest option, and highlights that seemingly small parts of packaging, like caps, can be a big source of microplastic exposure.
To see how different containers affect microplastic levels, French researchers tested various drinks in different types of packaging. They looked at water, soda, iced tea, lemonade, wine, and beer. The results were surprising:
These drinks contained significantly more microplastics when they were in glass bottles. In some cases, there were nearly 50 times more microplastics than in plastic bottles and cans.
Water in glass bottles had slightly more microplastics, but it was the least contaminated drink overall, no matter the container.
Wine in cardboard "brick" cartons had more microplastics, but generally, all the wines tested had very low levels of contamination.
The study showed that the amount of microplastics a person is exposed to can vary widely depending on what they drink and what container it comes from. For example, a single liter of lemonade from a glass bottle might have over 100 microplastics, while the same amount of water from a plastic bottle might have only about 1.6.
It’s important to note that the study only tested for microplastics and not even smaller particles called nanoplastics, which might have gone undetected.
It seems strange that a glass bottle would be more contaminated than a plastic one. The researchers were surprised by their own findings, but they have a theory: the cap.
They believe the paint used on the metal caps of glass bottles may be the source. During testing, they noticed that the microplastics found in the drinks often had the same color and material as the paint on the caps. They also saw tiny scratches on many of the caps, suggesting that friction during bottling, storage, or sealing could cause the paint to flake off as microplastic particles.
When the researchers cleaned the caps, the amount of microplastics in the drinks dropped significantly. The use of a cork on most wine bottles may also explain why wine had a much lower level of contamination.
While cleaning the caps won't completely solve the problem—microplastics can also come from airborne particles, contaminated water, or factory equipment—the findings suggest that beverage companies should rethink their packaging to protect consumers.
According to Association of American Medical Colleges although we don't have proof that microplastics harm humans, scientists are concerned. A study on mice found that even "clean" plastic particles caused negative effects. The worry is that real-world plastics contain harmful chemicals that disrupt hormones, which can affect important body functions like growth and reproduction. Experts suggest reducing plastic exposure as much as possible, especially for pregnant women and children.
Given that microplastics are everywhere, it's almost impossible to avoid them completely. The study found that even bottled and tap water contain them. However, you can take steps to reduce your exposure:
