The neuroscience of tickling: Why are we so ticklish?

Image
Tickling has puzzled people for centuries, prompting questions such as why certain touches make us laugh or squirm. Recent neuroscience research offers intriguing insights into the brain's response to tickling, suggesting that the phenomenon is more than just a playful annoyance. What is ticklish? Tickling actually refers to two different sensations. The first is a light touch to the skin, similar to the sensation of hair touching the neck or feathers gliding down the hand. This is called knizmesis, a mild itchy sensation that may make you want to brush away the source or scratch the area. Knismesis is not usually laughable; it's more like an itch. The second type of tickling, known as gargalesis, is more intense and usually causes laughter and squirming. Gargalosis occurs when someone constantly presses on certain sensitive areas of your body, such as your ribs or armpits. This type of tickling can be both pleasurable and irritating, and it is this sensation that has been the ...

Listening to the unheard: what animals can tell us today

Image
The natural world is not just a backdrop to human existence; it is a fundamental part of our emotional and spiritual well-being. Without wildlife, we would find ourselves in a world devoid of much of its beauty, fear, and spiritual richness. This sentiment resonates deeply when we consider the philosophical perspective of contemporary thinkers such as Mark Rowlands, who argues that we have an ethical duty to treat animals because they are part of the "moral community." In other words, just as we have an ethical obligation to treat other human beings with dignity and respect, we should also extend these considerations to animals. This view challenges the traditional notion of human exceptionalism, which often places humans at the center of the moral universe. Henry Dimbleby, the architect of the UK's National Food Strategy, suggests that the roots of human exceptionalism are deeper than we might have previously thought. Our perceived superiority over animals has led us to ...

How climate change makes typhoons stronger: the case of Shanshan in Japan

Image
Climate change is increasingly affecting weather patterns around the world, with some of the most dramatic changes occurring in regions like Japan. In recent years, the frequency and intensity of typhoons has become more prominent, leading to devastating effects on the country. One such example is Typhoon Shanshan which swept through Japan with unprecedented force, causing severe flooding and landslides But what makes Shanshan particularly remarkable is how its behavior underscores the broader impact of climate change. How climate change is shaping typhoon patterns Typhoon Shanshan moved across Japan at breakneck speed, raising the risk of flooding and landslides. According to experts, such rapid movement can be partly explained by global warming. Dr. Ito, a well-known Japanese meteorologist, notes that the westerlies—the steady wind that blows from west to east in the mid-latitudes—have shifted northward in Japan. This change is due to an increase in the temperature of the ocean in th...

Why did Homo Sapiens survive when other human species did not?

Image
As the sole survivors of the once diverse family tree of the human species, Homo sapiens  have demonstrated an unparalleled ability to adapt, thrive and dominate on the planet But what exactly distinguishes us from our now extinct relatives? Why did we survive while others like Neanderthals and Denisovans disappeared? This paper examines the unique factors that contributed to the success of Homo sapiens and offers insight into how our ancestors survived their closest competitors. Understanding the landscape of early human species About 300,000 years ago, Earth was home to several human species. Neanderthals inhabited parts of Europe and Asia, Denisovans lived in Asia, and early Homo sapiens roamed Africa. There were also other species, such as Homo erectus and Homo naledi, each of which was adapted to its environment. These species shared a common origin, but developed distinctive traits and behaviors appropriate to their unique habitats. Advantages of Homo Sapiens Cognitive abilit...

This temperature is significantly higher than typically required for superconductivity,...

Pink dolphins are endangered

Image
The Amazon River is home to one of the most unique and fascinating species on Earth, the pink river dolphin, also known as Inia geoffrensis. Distinguished by their bright pink hue, these freshwater dolphins face unprecedented challenges that threaten their survival. Recent research by a team of biologists, veterinarians and local fishermen has revealed alarming data about the health of these elusive creatures, which could hold the key to preventing another mass extinction like the one seen last year. Understanding the threat: Last year, more than 200 pink dolphins were found dead in Lake Tefe, a tributary of the Amazon River, due to extreme drought exacerbated by climate change. As the water level dropped and temperatures skyrocketed, oxygen levels in the water dropped, creating a deadly environment for both dolphins and fish. Scientists believe these extreme conditions are likely to become more frequent as the global climate continues to warm. To prevent a repeat of this tragedy, a gr...

The Power of the Placebo: Can Feeling Like It's Fake Improve Your Mood?

Image
In recent years, the concept of a placebo — a substance with no therapeutic effect that is used as a control when testing new drugs — has fascinated scientists and psychologists. Even more intriguing is the phenomenon known as "open placebo," where participants know they are taking a placebo but still experience real physiological and psychological benefits. As someone who has always been interested in the mind's power over the body, I find this area of research incredibly compelling. My take on the placebo: a psychological miracle From my point of view, the power of the open placebo challenges our traditional understanding of how treatment works. If a person knows they are taking a sugar pill, but still reports feeling less stressed, anxious, or depressed, what does that say about the mind-body connection? This suggests that faith—or perhaps more accurately, the act of participating in the healing process—has a profound effect on our well-being. Consider a recent Michiga...

Is a new Mpox strain the next global threat? Experts weigh in

Image
A recent surge in Mpox cases, especially in parts of Africa, has sparked fears and comparisons to the COVID-19 pandemic. Although experts agree that Mpox caused by the monkeypox virus is a serious health problem, they emphasize that it fundamentally different from COVID-19 in terms of transmission and impact. This article examines the current status of Mpox, its potential risks, and why it is unlikely to reflect the COVID-19 pandemic. What is Mpox and how is it spread? Monkeypox, also known as monkeypox, is an infectious disease that mainly manifests as a rash or skin lesions, often accompanied by fever and muscle aches. Unlike COVID-19, which spreads rapidly through airborne droplets, transmission of Mpox usually requires direct, prolonged contact. This is a fundamental difference that significantly limits the speed and scale of its spread. Dr. Marc-Alain Widdowson, head of the WHO European Division of High Risk Pathogens, elaborates: “People in Europe should not fear a situation simi...
