If you throw a mouse from a skyscraper onto something soft, let’s say – a stack of mattresses, the mouse would land and be stunned for a moment but probably survive. But, if you throw a dog and an elephant, the dog would break all of its bones and die in an unspectacular way, and the elephant would explode into a red puddle of bones and insides. Why would the mouse survive the fall, but the dog and elephant wouldn’t?

Two to six percent of people identify themselves as having predominantly homosexual attractions. Also, recent study has claimed that being gay is genetic. So is it true that we all have a gay gene?
The human brain is visibly divided into two sections – left and right, with each performing different set of operations. The structure has inspired one of the most widely accepted ideas about the brain: that the left section controls logic and the right section controls creativity.
If there’s nothing around to block our view, 5 kilometres (3.1 miles) is the furthest we can see. Atmospheric moisture, dust or smoke can reduce our visibility, but for the most part, everything we can see happens within an area of just 80 square kilometres. The higher up we go, the further we will be able to see. So how much of the Earth can we actually see at once?
By 2050, the UN estimates that as many as 3.2 million people will live to 100 compared to 316,000 in 2011. Also, a 2013 study from the University of Massachusetts found that 25 year olds today can look forward to "2.4 more years of a healthy life" while a 65-year-old today can expect to live 1.7 extra years - than people who lived 20 years ago.
See if you can answer this fish riddle. Imagine you’re a cargo driver who has agreed to transport several tanks of a critically endangered fish species to a new aquarium. Unfortunately, as you’re passing through shark-infested waters, the boat is battered by a fierce storm, tossing your cargo overboard. There’s one rescue sub at your disposal, but you only have enough fuel for one trip to the ocean floor. Before deciding to rescue them, you need to know where the tanks are so you can gather them all in one quick pass. Not a single fish can be lost.
Everything in this world is based on one algorithm. Theoretical physicist Geoffrey West talks about just how connected every living organism on earth is by way of energy and resources being supplied to cells — and by a methodology known as "quarter scaling."
There were many great scientists whose achievements were undervalued during their lifetimes, or who are nearly forgotten and often totally overlooked today. Here, Hank Green talks about five of those scientists – (Alfred Wegener, Rosalind Franklin, James Clerk Maxwell, Henrietta Swan Leavitt and Ada Lovelace) - who didn’t get the sort of appreciation they deserved in the episode of SciShow's “Great Minds Compilation” series.
