WTF is a Deep Fake?

Ready or not, deep fakes are here to stay. Deep fakes are going to change the way we trust information around us and even each other. The question is - are we prepared for the threat they cause while being able to harness their potential for good?

"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… "

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.

Ever notice how a year feels shorter now than when you were a kid? There's a scientific reason for that - and more importantly, you can actually change it.

In this science-backed guide to psychological time perception, you'll discover why your brain makes time feel like it's racing by, and the practical steps to make your life feel richer and longer. No mystical practices or time management gimmicks - just pure neuroscience and proven psychological techniques that actually work.

You'll learn:
The "Time Unit Paradox" that makes your years feel shorter as you age
Why your brain literally skips recording certain moments of your life
How to use novel experiences to expand your perception of time
The counterintuitive truth about routines and time blindness
Practical techniques to make your days feel fuller and more meaningful

Whether you're 20 or 60, these insights will transform how you experience time. This isn't about squeezing more into your schedule - it's about making the time you have feel abundant.
Based on research in neuroscience, psychology, and human behavior, this guide combines cutting-edge science with practical, actionable steps you can start using today.
Time isn't just passing by - you're actively creating your experience of it. Learn how to make it count.

In the 1600s, the Dutch East India Company employed hundreds of ships to trade goods around the globe. In order to fund their voyages, the company turned to private citizens to invest money to support trips in exchange for a share of the profits. In doing so, they unknowingly invented the world’s first stock market. So how do companies and investors use the market today? Oliver Elfenbaum explains.

Have you ever wondered how video game graphics have become incredibly realistic? How can GPUs and graphics cards render such incredibly detailed scenes? Well, in this video we're going to explore how just a bunch of data in your computer gets turned into realistic graphics. Additionally, we'll take a quick look into Ray Tracing, DLSS or Deep Learning Super Sampling, and many other complicated aspects of video game graphics.

We at Branch Education love to play video games, so this video has been one of our favorite ones to make thus far. It's kind of like getting to look under the hood of your childhood car. Also, it was surprising that practically all video games use similar basic steps to render each frame. Furthermore, as a fun fact, to create this video our team used 1x 3090ti, 3x 3090s, and the model that we tore down was a 3090.

There are just sooooo many topics in the realm of computer graphics that we couldn't cover. If you're interested in part 2 where we'll cover things like UVs, Normal Maps, Shadows, Reflections, Specular Reflections, and much more, tell us in the comments.

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.

Bill Gross has founded a lot of start-ups, and incubated many others — and he got curious about why some succeeded and others failed. So he gathered data from hundreds of companies, his own and other people's, and ranked each company on five key factors. He found one factor that stands out from the others — and surprised even him.

The nanoscopic world is wild!! Looking at basic objects like a grain of salt under an electron microscope looks like nothing you would have expected. Furthermore, have you ever wondered whether seeing a single atom is possible? Or how do scientists and engineers create only a few nanometers wide transistors? In this video, we will explore the electron microscope and how they are used to see nanoscopic objects. Specifically, we'll look at the Transmission Electron Microscope and the Scanning Electron Microscope and dive into how they work.

Are Vitamins and Supplements a Scam?
Click https://go.mycopilot.com/johnny-harris to get 14 days FREE with your own personal trainer!

The supplements industry — with all its vitamins, weight loss pills, workout powders, and hormones — has been growing exponentially over the last couple of decades despite there being no increased regulations for them. We wanted to know — are supplements dangerous to take, and are they even effective?

Thank you to the experts we spoke with that helped with our research in this story:
Dr. C. Michael White, Pharm.D., FCP, FCCP
Dr. F. Perry Wilson, MD, MSCE
Dr. Edzard Ernst, MD, PhD, MAE, FMedSci, FRSB, FRCP

And thank you to Ryan Howkins, the founder of the Lion’s Mane Recovery subreddit, who brought the Lion’s Mane story to our team. You can find the subreddit here: http://reddit.com/r/LionsManeRecovery

We use touchscreen displays for hours every day, but do you know about all the intricate layers and components that make them work? This episode goes into the structure and basic function of a touchscreen display. What goes into making toughened glass strong, how do capacitive touchscreens work, and how do OLEDs work? The merging of these technologies is what arguably makes the smartphone what it is! Take a look and learn more.

Addendum & Erratum
LG Prada Predated the Iphone. LG Prada was released announced December 12th 2006 and sales started in May 2007.

5:43 Most smartphones use a pentile subpixel layout which is 2x Green for 1x Red and 1x Blue.

7:25 1Pixel = 1G+1B or 1G + 1R. Thus the latest phones are closer to 6.67Million itty bitty lights.

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.

Hate to break it to you, but your truffle oil wasn't made from truffles. Your vanilla extract? Well, that's probably just a lab-made derivative of crude oil. And your shaker of Parmesan cheese? It probably has wood pulp inside.

You might feel the companies behind these food products are using deceptive packaging — but it's legal. However, there's a whole other level of trickery that's completely illegal: food fraud. That's when criminals bottle up corn syrup and call it 100% honey, or when they pass off cheap mozzarella as pure Parmigiano-Reggiano.

Globally, the fraudulent food industry could be worth $40 billion. It hurts legitimate producers, funds criminal activities, and can even harm consumers. We head around the world to uncover how producers get away with food deception and how we can spot the real stuff.
