The intensity of sunlight on Earth is about 1300 Watts per square meter. When you focus the sun’s rays using a magnifying glass (or in this case sphere of water) you can increase the intensity roughly ten thousand fold. This increases the temperature of wood to its autoignition point starting the reaction with oxygen in […]
There’s a theory floating around the science community that we live in a hologram. The crazy part? There’s a chance it’s correct! Watch this episode of Life Noggin to learn all about this theory! [Life Noggin]
Here’s a totally useless fact… unless you decide to travel to one of the poles, of course. Given that they are every possible hour all the time, or more aptly technically in every time zone, it may come as no surprise to you that there are no official time zones at the poles. Nevertheless, groups […]
You might not need to throw away your broken glasses and get new ones anymore, thanks to these unique materials that can heal themselves! Learn all about them in this episode of SciShow! [SciShow]
You’ve probably been told that eating too much salt is bad for you, especially if you have high blood pressure. But what exactly does salt do to our bodies that can make it so hard on our hearts? [SciShow]
On September 2016, China unveiled the world’s largest radio telescope, and has started test operations searching for signals to understand the origins of the universe and the Big Bang. This 500 metre Aperture Spherical Telescope, or FAST, has been constructed over 5 years in a 45 million year old crater in Southern China. The remote […]
You can’t open up a magazine without seeing someone with impossibly smooth skin selling some sort of “anti-aging” cream, but could some of these products actually work? According to scientic litterature, yes, they do work, but there’s mostly only 1 thing that’s really effective in these creams: Retinol. Watch this episode of SciShow to learn […]
Our diets are more global than we realize, because our common food crops and animals were domesticated far away in diverse locations. In this video, Minute Earth observes why the common apple pie is not American and the Pizza isn’t really Italian. [Minute Earth]
De-extinction, or using the power of modern biotechnology to bring back extinct species like mammoths and dinosaurs, would be cool. But is it really as easy as the movies make it look? Or do the cruel hands of time make it impossible? This weel we look at the technical and ethical hurdles behind the science […]
Money laundering is the term for any process that “cleans” illegally obtained funds of their “dirty” criminal origins, allowing them to be used within the legal economy. And the practice is about as old as money itself. But how does it actually work? Delena D. Spann describes the ins and outs of money laundering. [TED […]
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]
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. It […]
