Many scientists have attempted to make functional artificial blood in recent years, but the process isn’t quite perfect yet. However, things might be about to change thanks to the UK’s National Health Service and stem cell technology. Learn all about the technology of “Fake Blood” in this interesting episode of the SciShow. [SciShow]
https://www.youtube.com/watch?v=cTLBrqcuLBU Chlorosulfonic acid is just like the blood of a xenomorph when applied to an organic substance: it eats its way through it. Chlorosulfonic acid is a super acid, an acid that has an acidity greater than 100% pure sulfuric acid. Chlorosulfuric acid (IUPAC name: sulfurochloridic acid) is the inorganic compound with the formula HSO3Cl. […]
In this video, Youtuber “Today I Found Out” explains the truth about flammable flatulence. That’s right: The science of people setting fire to their farts. Farts are primarily made in two ways – from swallowing air and digesting food. Swallowed air delivers nitrogen and oxygen to the digestive tract, where the latter is mostly, if […]
More than 300 million people around the world suffer from asthma, and around 250,000 people die from it each year. But why do people get asthma, and how can this disease be deadly? Christopher E. Gaw describes the main symptoms and treatments of asthma. [TED Ed]
Watch as Neil deGrasse Tyson explains the universe while eating increasingly spicy wings, starting with the relitively mild sriracha, and ending with Blair’s Mega Death with Liquid Rage hot sauce. Star Talk host, Hayden Planetarium director, and astrophysicist extraordinaire Neil deGrasse Tyson has a brilliant knack for breaking down big scientific ideas to the masses. […]
There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course […]
In this episode of “It’s OK To Be Smart,” host Joe Hanson investigates how closely related we all really are. Basic math tells us that all humans share ancestors. But you’ll be amazed at how recently those shared ancestors lived. Thanks to genetic data in the 21st century, we’re even discovering that we really are […]
Watch as America’s favorite astrophysicist takes a look at the somewhat-questionable science behind big summer movies like ‘Guardians of the Galaxy 2″ and “Alien: Covenant.’ [The Late Show with Stephen Colbert]
NASA is offering a prize to coders who can help speed up the supercomputer software used to improve aircraft performance. You’ll need to be a US citizen and able to work with Modern Fortran. While many people think of NASA as being a space organization, it also works on aeronautics closer to home. This includes […]
One day, everything will end, even the universe. But before that happens, stars will start dying one after the other. The last ones to remain will be white dwarfs, the corpses of stars, which will continue burning for a long, long time before finally becoming Black Dwarfs. [Kurzgesagt – In a Nutshell]
