How Chocolate Can Help Repair Spinal Damage
Innovative research conducted in Lausanne, Switzerland has shown that a combination of neurotransmitters and electrical stimulation can restore movement to the lower limbs of previously paralysed rats. But in order for this motion to be made voluntarily the rats must be motivated to walk. This motivation comes in the form of cheering, visual cues, and [...]
A Time-Lapse Map of Every Nuclear Explosion Since 1945 – by Isao Hashimoto
Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project’s “Trinity” test near Los Alamos and concluding with Pakistan’s nuclear tests in May of 1998. This leaves out North Korea’s two alleged nuclear tests in [...]

Space Junk & The Swiss ‘Janitor Satellite’
Space junk is a real problem. NASA now tracks around 20,000 pieces of debris orbiting Earth, most of them larger than 10cm across. Since the average speed of a collision between orbiting objects is 10 km/s these pieces of trash can cause a lot of damage despite their small size. Scientists in Switzerland have a [...]

Common Physics Misconceptions
What if you thought the earth was flat? And then you found out it isn’t?
Corn Flour Fireball
Corn flour blown through a funnel produces an excellent fireball. This both looks cool and demonstrates some interesting science. In any chemical reaction, the reactants must mix with each other significantly in order to increase the rate of reaction. Here we demonstrate that corn flour on a spoon burns slowly, but blown from a funnel, [...]
