Have you ever entered a room and instantly felt uneasy or uplifted, even without any apparent reason? Science suggests there may be a biological explanation for this phenomenon. Emily Mcdonald, a neuroscientist and brain recently highlighted the role of chemo signals—subtle chemical cues that linger in an environment long after people have left.
These chemo signals, which are released through bodily secretions like sweat, can remain in a space for an extended period. When new individuals enter the same environment, they may unconsciously absorb these cues, influencing their emotions and behavior. According to the study, people often experience anxiety or joy upon entering a room, depending on the emotional state of those who previously occupied it.
This response is closely tied to the way our olfactory system functions. Unlike other sensory inputs, scent-based signals can bypass conscious thought and directly activate the limbic system—a part of the brain responsible for emotions, memory, and instinctive behavior. This means that without even realizing it, we may start feeling a certain way simply because of the chemo signals present in our surroundings.
The implications of this research emphasize the importance of our environment and the company we keep. If emotional states can be chemically imprinted in a space, it becomes even more crucial to create positive atmospheres at home, work, and social settings. Understanding how our surroundings influence us at a subconscious level could be key to improving mental well-being and fostering healthier interactions.
While further research is needed to explore the extent of chemo signal influence, this study sheds light on a fascinating aspect of human perception—one that suggests our ability to "sense the vibes" of a room may not be as mystical as it seems, but rather, deeply rooted in science.
Meanwhile, research says that the human body is far more perceptive than that and there have been lesser-known senses like equilibrioception, which helps us maintain balance, proprioception, which allows us to know where our body parts are without looking, and chronoception, our ability to perceive the passage of time.
And these extra senses are just for humans, there are other species that have sensory reception that we cannot even fathom. For instance, honeybees have iron oxide in their abdomen that allows them to detect shifts in the Earth's magnetic field, helping them navigate back to their hive. Birds and some sea creatures also use magnetic sensing to migrate across vast distances.
For centuries, the idea of a "sixth sense" has captivated human imagination. While traditionally used to describe an unknown or supernatural ability. However, certain researchers have argued that it could be better understood as an "X sense" or something that is still undiscovered. It could also refer to a heightened form of perception.
In Indian philosophy, the mind itself, or "manas," is often considered a sixth sense, coordinating our primary five senses with other cognitive functions. Western cultures, on the other hand, often equate the sixth sense with extrasensory perception (ESP) or intuition. In Celtic traditions, it was known as "second sight," believed to allow some individuals to predict events, including impending death.

Danish pharmaceutical giant Novo Nordisk scored a huge legal victory that restricts compounding pharmacies from marketing or selling cheaper, unapproved versions of its blockbuster weight loss drugs Ozempic and Wegovy. On Monday, US District Judge Mark Pittman denied the Outsourcing Facilities Association's bid for a preliminary injunction that would have prevented the FDA from taking action against its members for making copies of semaglutide, the active ingredient in Ozempic and Wegovy.
Compounding is a process where pharmacies mix ingredients of a drug to create a specialised version for specific patients. Say someone is allergic to a dye in a branded medication or needs a liquid form, and the main manufacturer only sells capsules. In that case, the patient can turn to a compounded version or the liquid form. Moreover, when drugs are in short supply, they can be compounded in larger quantities to help fill the gap.
Hundreds of thousands of people flocked to these compounding firms when they didn't have enough money to afford the costly weight loss treatments. The prices of both Wegovy and Ozempic rose exponentially, given the skyrocketing demand in the last two years. Notably, the Texas judge's verdict came in response to a February lawsuit from a compounding trade group against the FDA's determination that the active ingredient in those drugs, semaglutide, is no longer in shortage in the US. The decision also means the FDA can start targeting federally regulated 503B pharmacies, which manufacture compounded drugs in bulk with or without prescriptions, after May 22. The agency’s actions can include product seizures and warning letters to pharmacies.
Semglutide is the synthetic version of GLP-1, a natural hormone produced in the intestines that regulates blood sugar, appetite, and digestion. Now, every time you eat, your body produces various hormones, including GLP-1. These are called post-nutrition hormones and help you absorb the energy you just consumed.
GLP-1 travels to your pancreas, prompting it to produce insulin. It also travels to the hypothalamus in your brain, which gives you the feeling of being full or satiated. Ozempic imitates this hormone, thereby silencing the food chatter in the brain. Interestingly, for some people this food chatter is really quiet ( people with low appetite), and for others, it is an outburst (people who generally binge eat.) So with Ozempic, silencing this self-talk in the brain, people tend to lose their appetite and eventually weight.
However, it is important to note that losing weight includes not just fat but muscle as well. Losing too much muscle can lead to reduced strength and a shorter life span. Notably, records show that most people who start taking them stop it at 12 weeks; therefore, it is important for some but not for others.

As we today observe the World Dance Day, let us look at what dancing can help us with. Of course, the physical benefits are there. When you move your body, do any sort of physical activities, you are working out in some form and it helps you stay fit. Like everyone have their fitness regime, your dance routine can also help you stay fit. In fact there are certain fitness regime, including Zumba that keeps you fit through dance.
However, the benefits go much beyond just physical fitness, dancing can actually help you live a stress free life.
In one of the latest trends in TikTok, people are bringing back pangs of nostalgia to the internet with their 90s dance on rapper Doechii's song 'Anxiety' from the "The Fresh Prince of Bel Air".
Why is this trend important? With big names also jumping in and dancing to the rhythms, including Wil Smith and Tatyana Ali, experts say that this is helping ordinary people normalize anxiety.
Certain anxiety disorders are marked by persistent, or excessive worry. It could be fear about situations. As per the Mayo Clinic, these moments of anxiety can include panic attacks and sudden episodes of intense fear or discomfort
Research suggest that creative activities, including dancing can help relieve this stress. Dancing also engages multiple areas of the brain and demands full attention, which can then shift the focus from anxiety feelings. Supporting this idea, a 2021 study from UCLA Health found that conscious dance led to mental health improvements in a large majority of participants, particularly those dealing with anxiety, depression, or a history of trauma.
Dance involves full-body movement and coordination. This kind of physical activity stimulates the release of endorphins—natural chemicals in the brain that act as mood boosters and stress relievers. During a panic attack, when anxiety can feel overwhelming, these endorphins help calm the body and mind.
Engaging in dance also activates deep breathing patterns, especially in structured styles like Indian classical dance. This is important because panic attacks often lead to rapid, shallow breathing or hyperventilation. The breath control involved in dancing can help slow things down and regulate the body’s response.
In addition, dance improves body awareness. When someone is in the middle of a panic attack, they often feel disconnected or dissociated from reality. Focusing on movement—on the placement of your arms, the rhythm of your steps, the tension in your muscles—can bring attention back to the present. This grounding effect helps reduce the intensity of the attack and prevents it from escalating.
Experts explain that one reason dance can be so effective is because it serves as a powerful distraction. Instead of spiraling into anxious thoughts, the brain is forced to concentrate on movement, rhythm, and coordination. This temporary shift in focus can prevent panic from taking over.
Dance also builds mindfulness, a practice often recommended in therapy. Whether it's through a slow classical routine or a high-energy freestyle session, dance requires attention to the now. The combination of mental focus and physical release gives the body a chance to reset and relax.

Last year in June, when a woman collapsed on an escalator at Buffalo's airport, and Phil Clough, who is an experienced emergency medical responder knew exactly what to do. He and a bystander, as the Washington Post reported, quickly laid the woman flat on her back. They checked her pulse and breath. Her pulse was faint and her breathing was shallow and erratic. A few moments later, she stopped breathing altogether.
Realizing she might be experiencing a cardiac arrest, Clough immediately began performing chest compressions. He pressed hard and fast on the center of her chest while other bystanders called 911 and fetched an automated external defibrillator (AED). Within seconds of receiving a shock from the AED, the woman opened her eyes. By the time the airport rescue team arrived, just minutes later, she was conscious and able to speak.
Clough’s quick actions saved the woman’s life, but he credits his preparedness to a life-changing incident several years earlier. After witnessing a woman collapse at his gym and feeling helpless, he took a college course to become certified as an emergency medical responder. This training allowed him to respond with confidence when faced with a life-or-death situation.
The woman in Buffalo was fortunate that bystanders knew how to respond. Unfortunately, most people who experience cardiac arrest do not receive immediate help.
According to the American Heart Association, more than 350,000 cardiac arrests occur outside of hospitals in the U.S. annually. Tragically, 90% of these individuals do not survive, often because help arrives too late. For each minute that passes without intervention, a person’s chances of survival decrease by 10%. However, with prompt cardiopulmonary resuscitation (CPR) and an AED shock if necessary, survival rates can double or even triple.
Despite the importance of swift intervention, fewer than half of people who suffer cardiac arrest outside of a hospital setting receive immediate assistance. This lack of action is often due to a lack of training and preparedness. Cardiac arrest can happen anywhere, but with public access to AEDs and trained bystanders, survival rates could improve dramatically.
A crucial part of treating cardiac arrest is the use of an AED, a portable device that delivers an electric shock to the heart. The AED analyzes the heart’s rhythm and guides the user through the steps to apply a shock if needed. Although many states require AEDs to be available in public places such as airports and malls, they are not always easy to find. A study spanning 2019 to 2022 revealed that in public settings, AEDs were used only 7% of the time, and CPR was performed 42% of the time after a cardiac arrest incident.
To address this issue, PulsePoint, a nonprofit organization, has registered 185,000 AEDs in 5,400 U.S. communities, reports the Washington Post. The group’s goal is to help communities build their AED registries and integrate them with local 911 services. In addition, PulsePoint’s mobile app alerts trained CPR responders about nearby cardiac arrests and identifies the closest AEDs, enhancing the chances of saving a life.
While CPR and AED knowledge can save lives, many people hesitate to intervene during an emergency due to fear of making a mistake, lacking confidence, or worrying about legal liability. However, all 50 states and Washington, D.C. have “Good Samaritan” laws that protect individuals from legal consequences when they provide help in a medical emergency.
Lack of CPR training is another significant barrier. A study found that only 18% of people had received CPR training within the last two years, which is crucial for skill retention. Although many people have received CPR training at some point in their lives, the skills may be outdated or forgotten.
To address this, some states have made CPR training mandatory for high school graduation, and countries like Denmark and Norway have implemented similar requirements. In the U.S., CPR courses are widely available online and in-person, and many take just a few hours to complete. These courses teach individuals the basics of CPR, which involves performing chest compressions at a rate of 100 to 120 per minute and a depth of at least two inches.
