Transcript You may think you know exactly what race you are, but how would you prove it if somebody disagreed with you? The fact is, even though race drives a lot of social and political outcomes, race isn't real.  One of the first people to attempt to categorize humans according to race was a German scientist in around 1776. He came up with 5 different groups according to physical appearance and geographic origin of their ancestors. Americans of European descent eagerly bought into this type of thinking around the same time.  Some historians have said the idea that there are different races helped them resolve the contradiction between a natural right to freedom and the fact of slavery. If whites were their own distinct category, then they could feel a lot better about denying freedom to people who they labeled black and decided were fundamentally different. But as political priorities change, definitions of race in America adjust right along with them. For exampl...

Cryonics is the practice or technique of deep-freezing the bodies of people who have just died, in the hope that scientific advances may allow them to be revived in the future. Video Transcript Just last month, a husband asked CryoAsia, a bio-freezing technology company, to freeze the body of his wife who died of cancer. This is the second case of frozen humans in Korea after a son had his mother who had passed away in her 80s frozen and preserved last year. The preservation period is 100 years which currently costs about 86,000 USD. CryoAsia explained that even if the preserved body is thawed in the future, it is extremely unlikely that the subjects will wake up. But the calls still continue regardless, from those who consider cryonics as their only remaining option. The husband also expressed that after suddenly having to part with his wife, he was struggling but cryonics came as a strand of hope and a great comfort.  The first Korean cryonics applicant had also told...

  WASHINGTON, Aug 16 (Reuters) - U.S. auto safety regulators on Monday opened a formal safety probe into Tesla Inc's  (TSLA.O)  driver assistance system Autopilot after a series of crashes involving Tesla models and emergency vehicles. The National Highway Traffic Safety Administration (NHTSA) said it had identified 11 crashes since January 2018 in which Teslas "have encountered first responder scenes and subsequently struck one or more vehicles involved with those scenes." The probe will take in 765,000 U.S. vehicles with Autopilot built since 2014. Tesla shares closed down 4.3% on the news. NHTSA, which closed an earlier investigation into Autopilot in 2017 without taking any action, has come under fire for failing to ensure the safety of the system that handles some driving tasks and allows drivers to keep their hands off the wheel for extended periods. After the new probe, the auto safety agency could opt to take no action, or it could demand a recall, which might ...

Although there are many bald celebrity icons like The Rock, Jeff Bezos, the Dalai Lama, and Shaquille O'Neal, losing your hair is not something men aspire to. Buisness Insider journalist Graham Flanagan asked a dermatologist to explain the scientific reasons that some men lose their hair. Dr. Jennifer Chwalek is a Board Certified dermatologist at Union Square Laser Dermatology in New York. Chwalek explained that hair loss is not directly related to low levels of testosterone. Going bald is largely determined by genetics, and how sensitive a person's hair follicles are to a byproduct of testosterone called dihydrotestosterone. Transcript: Look at that beautiful bald man, his oozing swagger and confidence. He owns it. But it wasn't always like this. This is Rob. He's 33. This is also Rob. He started to lose his hair when he was about 20. So, what happened? Why did Rob go bald, and what does it mean?  There's something about being bald and owning it. I mean, loo...

  Transcript: A few years ago, I felt like I was stuck in a rut . So, I decided to follow in the footsteps of the great American philosopher Morgan Spurlock and try something new for 30 days. The idea is actually pretty simple. Think about something you've always wanted to add to your life and try it for the next 30 days.  It turns out 30 days is just about the right amount of time to add a new habit or subtract a habit like watching the news from your life. There's a few things that I learned while doing these 30-day challenges. The first was instead of the months flying by forgotten, the time was much more memorable. This was part of a challenge I did to take a picture every day for a month and I remember exactly where I was and what I was doing that day. I also noticed that as I started to do more and harder 30-day challenges, my self-confidence grew. I went from desk dwelling computer nerd to the kind of guy who bikes to work for fun. Even last year, I ended up hik...

Please watch the video and read the transcript. Transcript: It's a touch of Disneyland, deep in the rural province of Bolu in northwestern Turkey . Hundreds of little castles, in fact, luxury houses with pointy towers and fairytale charm, if it wasn't for the barbed wire and the fact that they're all empty and just aren't selling.  Situated halfway between Istanbul and Ankara , the region is popular with tourists who like hiking in the vast forests here. A Turkish developer spent over $100,000,000 building homes for Arab customers. "The inspiration for the project came from our work in Kuwait and the Gulf countries. We talked with our customers there and came up with more than one design based on their demands. The choice in the end was for a design like this." While the outcome is certainly a matter of taste, the economic situation in Turkey is clearly bad. The economy is retracting, the lira f...
