There's a long-held myth that cracking your knuckles can damage your hands. The sound definitely might make people around you cringe, but what's making those noises, and is it actually bad for you?

There's a space in your joints filled with synovial fluid, a liquid that reduces the friction in your joints when you move. It contains gases (oxygen, nitrogen, and carbon dioxide).

When you pop a joint, you stretch out that space between the bones. That expanding space creates negative pressure, like a vacuum, that sucks in the synovial fluid. It forms bubbles, which then collapse, and that's what you hear.

Most medical sources agree that unless you experience pain when you pop your joints, you're probably fine to keep doing it. Researchers (including one man who cracked his knuckles on just one hand for 60 years) haven't established a connection between cracking your knuckles and arthritis.

One 1990 study of 300 people did find that cracking knuckles over a long period of time led to hand swelling and decreased grip strength, but there hasn't been any follow-up research on that.

Neuroanatomist Dr. Jill Bolte Taylor explains the 4 key ”characters” of the brain, and how understanding each can expand your perception of yourself, and the world, forever.




At age 37, neuroanatomist Dr. Jill Bolte Taylor suffered a stroke that would take her eight years to fully recover from. This is how it changed her understanding of the brain.

In this interview, Dr. Jill draws a map of the human brain, explaining how it is comprised of four distinct modules, each serving a unique role in function and personality. This combination of cognitive and emotional components gives rise to the multidimensional characters within each of us.

Are you looking to be more rational, more creative, more forgiving, or perhaps less rigid in your thinking? Dr. Jill suggests that by becoming aware of the four modules of our brains, we can consciously choose to engage specific parts. This awareness allows us to harness the true power of our brains and shape who we want to become, ultimately fostering less anxiety, more inner peace, and a vastly more purposeful life.

----------------------------------------------------------------------------------

About Dr. Jill Bolte Taylor:

Dr. Jill Bolte Taylor is a Harvard-trained and published neuroscientist. In 1996 she experienced a severe hemorrhage (AVM) in the left hemisphere of her brain causing her to lose the ability to walk, talk, read, write, or recall any of her life. Her memoir, My Stroke of Insight, documenting her experience with stroke and eight-year recovery, spent 63 weeks on the New York Times nonfiction bestseller list and is still routinely the #1 book in the category Stroke in the Amazon marketplace.

Dr. Jill is a dynamic teacher and public speaker who loves educating all age groups, academic levels, as well as corporations and not-for-profit organizations about the beauty of our human brain. She focuses on how we can activate the power of our neuroplasticity to not only recover from neurological trauma, but how we can purposely choose to live a more flexible, resilient, and satisfying life.

In 2008 Dr. Jill gave the first TED talk that ever went viral on the Internet, which now has well over 27.5 million views. Also in 2008, Dr. Jill was chosen as one of Time magazine’s “100 Most Influential People in the World” and was the premiere guest on Oprah Winfrey’s “Soul Series” webcast. Her new book, Whole Brain Living – the Anatomy of Choice and the Four Characters That Drive Our Life is a #1 release on Amazon in categories ranging from Neuroscience to Nervous System Diseases and Stroke.

Are More Expensive Clothes Actually Better Quality?

“You get what you pay for” - I’m sure you’ve heard this saying many times before; and that can certainly be true in many areas. A higher price often comes with better quality/service/experience, but not always; so in today’s video we’re going to find out if that applies to fashion.

Design and branding are inherently a part of human nature. They serve as a way of signaling to others, non-verbally, who we are, what we believe in, and what is important to us.

There was a time when consumers were exclusively interested in a company's products — upgrades, different flavors, different colors.

But today, consumers want to know if the companies that they are buying from are worthy of their money. Do the companies practice good ethics? Do they have certain values? That's something that we have really never seen before.

How Big is The Universe?

We begin at the familiar blue and green orb we call home and zoom out to explore the vastness of space. From the Moon, our closest cosmic neighbor, to the edges of the observable universe, prepare to be astonished by the sheer scale of everything that exists.

Travel with us as we venture past the Moon, understanding its distance in terms we can grasp. Witness the Sun, not just as a source of light, but as a milestone in the vastness of our solar system. We don't stop there; Mars, Neptune, and the outer reaches of our solar neighborhood await.

Discover the awe-inspiring distances to the Voyager 1 probe, the enigmatic Oort Cloud, and the neighboring star system of Alpha Centauri. As we sail through the Milky Way, understand our position in the grand scheme of things, where our entire history is just a whisper in the cosmic wind.

Our voyage takes us further, to the Local Group, Virgo Supercluster, and the staggering Laniakea Supercluster. We contemplate the Great Attractor's pull and our place in this immense heaven.

Confront the boundaries of the observable universe and ponder the mystery of what lies beyond. This video is not just a journey through space but a journey of perspective. Join us in marveling at the universe's grandeur and our humble place within it.

Michel Foucault was a philosophical historian who questioned many of our assumptions about how much better the world is today compared with the past. When he looked at the treatment of the mad, at the medical profession and at sexuality, he didn't see the progress that's routinely assumed.

FURTHER READING

“Michel Foucault (1926-1984) was a French 20th-century philosopher and historian who spent his career forensically critiquing the power of the modern bourgeois capitalist state, including its police, law courts, prisons, doctors and psychiatrists. His goal was to work out nothing less than how power worked and then to change it in the direction of a Marxist-anarchist utopia. Though he spent most of his life in libraries and seminar rooms, he was a committedly revolutionary figure, who met with enormous popularity in elite Parisian intellectual circles (Jean Paul Sartre admired him deeply) and still maintains a wide following among young people studying at university in the prosperous corners of the world…”

Scientists like Prof Sinclair have evidence of speeding up, slowing, and even reversing aging.
Thanks to LastPass for sponsoring this video. Click here to start using LastPass: https://ve42.co/VeLP

What causes aging? According to Professor David Sinclair, it is a loss of information in our epigenome, the system of proteins like histones and chemical markers like methylation that turn on and off genes. Epigenetics allow different cell types to perform their specific functions - they are what differentiate a brain cell from a skin cell. Our DNA is constantly getting broken, by cosmic rays, UV radiation, free radicals, x-rays and regular cell division etc. When our cells repair that damage, the epigenome is not perfectly reset. And hence over time, noise accumulates in our epigenome. Our cells no longer perform their functions well.

To counter this decline, we can activate the body's own defenses against aging by stressing the body. Eat less, eat less protein, engage in intense exercise, experience uncomfortable cold. When the body senses existential threats it triggers longevity genes, which attempt to maintain the body to ensure its survival until good times return. This may be the evolutionary legacy of early bacteria, which established these two modes of living (repair and protect vs grow and reproduce). Scientists are uncovering ways to mimic stresses on the body without the discomfort of fasting. Molecules like NMN also trigger sirtuins to monitor and repair the epigenome. This may slow aging.

Reversing aging requires an epigenetic reset, which may be possible using Yamanaka factors. These four factors can revert an adult cell into a pluripotent stem cell. Prof. Sinclair used three of the four factors to reverse aging in the retinal cells of old mice. He found they could see again after the treatment.

On April 8, 2024, the Moon’s shadow fell upon the Earth, creating a total solar eclipse across North America. If you had the chance to see it, you're surely glad you didn't miss it. It’s an amazing coincidence that total eclipses happen at all — and that we’re alive at a time when we can see and predict them. We made this video so you can learn how to watch an eclipse safely, what to look for during an eclipse, why eclipses happen, and how eclipses have helped advance scientific research.

Can you imagine a party where every movement and every visual detail were governed by a complex system of rules and procedures? For centuries, such rituals were commonplace for European nobility. And while they’ve gone out of fashion, we recognize the components under a familiar label: ballet. Jennifer Tortorello and Adrienne Westwood outline the history of this graceful and precise dance.
