Mastering any physical skill takes practice. Practice is the repetition of an action with the goal of improvement, and it helps us perform with more ease, speed, and confidence. But what does practice actually do to make us better at things? Annie Bosler and Don Greene explain how practice affects the inner workings of our brains.

Lesson by Annie Bosler and Don Greene, animation by Martina Meštrović.

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

This is the world's largest construction project, and also one of the most controversial. NEOM, four letters that reflect the inordinate ambition of one country: Saudi Arabia. A huge region in the north-west of the country, where futuristic cities are due to spring up. The Line, Oxagon, Trojena, Sindalah and other new locations that was unveiled recently: Leyra, Norlana, Sirana and Aquellum. But between the 3D images and reality, how far advanced is the work? That's what we're going to find out today, in this new episode of Looking 4.

"Strangely, and rather awkwardly, it seems no human being can ever really grow up sane unless it has been loved very deeply by someone for a number of years in its early life. But we’re still learning what parental love might actually involve. The word ‘love’ trips lightly off the tongue and few parents – even the most disagreeable ones – would ever resist a claim that they felt the emotion deeply, but that doesn’t mean that loving behaviour is any easier to understand in theory or practice in reality… "

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.

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.

In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around ... thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move.

The field of computer science summarised. Learn more at this video's sponsor https://brilliant.org/dos

Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

A couple of notes on this video:
1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work!
2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example.
3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

Behind the Porsche brand, is a prodigious but dark story… A story of success, tragedy, innovation and destruction.

But to make sense of all this, we have to go back in time to where it all started, 1898. Ferdinand Porsche had just left his job behind to kickstart a new career into the automotive world.

During the next few decades, he created some of the fastest and most groundbreaking vehicle designs for other car manufacturers, turning himself into one of the greatest engineers of all time. And yet, after founding his own car company, this success fell into a darker path when Porsche was embroiled with military projects for the German Regime, which ended himself in prison and eventually costing his life.

So buckle up, we’re going on a journey to uncover the true story of Porsche, and how they managed to transformed itself to one of the greatest luxury car brands, it is today.

Millions of Americans are administered anesthesia each year. Since 1846, doctors have used a variety of drugs to make patients unconscious for surgery, but even though the medications have changed, there's one thing that remains the same— it works. But how exactly?

Following is the transcript of the video:

Narrator: When you go to sleep, if I pinched you, you'd be up. If I shook you, you'd be up, right? But under anesthesia, I'm gonna pinch you and do a full operation and you're not up. So it's really further on the spectrum of unconsciousness.

Narrator: When you wake up after being put under with general anesthesia you barely feel like any time has passed. You could have been out for an hour or a day and you wouldn't know the difference.

Fong: When you go to a natural sleep, people call your name, your alarm goes off, you wake up, right? This is not what is gonna happen during general anesthesia. You're gonna be unconscious.

Narrator: You're closer to being in a coma than being asleep.

Anesthesia was first used during surgery in 1846. The drug provided at that time was ether. Now anesthesiologists more commonly use a combination of drugs like propofol and fentanyl which interrupt neural pathways so you don't feel pain and you don't remember the surgery.

Fong: Three things that you need for general anesthesia are you need amnesia so that they don't remember, analgesia so they have pain relief and then operating conditions for the surgeon. Some surgeries you need the patient to be very relaxed so you would use a muscle relaxant. Other surgeries the patient just needs to be asleep and anesthetized but they don't need relaxation so how they do that varies upon the different medications that you're using. Some will depress excitatory neurons and some will enhance inhibitory neurons.

Narrator: Excitatory neurons, for example, get excited and send signals to other neurons to fire. Depressing them means less signals telling your brain you're in pain. Inhibitory neurons do the opposite. They make it harder for neurons to generate these electrical signals. In either case this means fewer active neurons overall which is important because when your body is being poked and prodded, neurons would typically fire to tell your brain you're in pain. If those neurons aren't firing, your brain doesn't know that your body is, well, being cut open.

Fong: Basically it interrupts the pathways and the communication between your neural networks. We're aiming for them to be not in pain by looking at their vital signs, their heart rate, their blood pressure. Then we want to make sure that they're unconscious.

Narrator: Without anesthesia, many important surgeries wouldn't be possible because they'd be way too traumatic.

Fong: Surgery didn't move forward, really, until anesthesia moved forward. You know, you watch those old movies. They give you a swig of alcohol, they put a tourniquet and they hack your leg off. People don't do well with that, right? If you had a bad heart, that would be the end of that.

Narrator: After the procedure is complete the doctors stop administering the meds and the most powerful effects of the drugs wear off but even though you're conscious again you might continue to experience some of the drugs side effects.
