The Moon: is has a tail and we would have a catastrophic planet without it

The Moon has a tail made up of sodium atoms very thinly dispersed throughout the small Moon exosphere. Moons atmosphere, called exosphere, is so rare that when it is full Moon and it is between us and the Sun, its atmosphere gets pushed around towards the Earth. This way we will be able to reside […]

Lakes that explode? Almost: they erupt

Lake Nyos, from Cameroun, released 80 million cubic meters of carbon dioxide gas in its surroundings with a speed of 50 kmph and suffocating everything within a 25 km radius. That is tough. Since then the researchers have found several such lakes that erupt and all of them are in Africa. These lake eruptions are […]

Motor proteins, the things that make the cell work and divide

The motor proteins are proteins from within our cells that have the role of carrying cellular material around the cell (food, signaling molecules, genetic information). It uses the cells highway system called microtubule cytoskeleton created from a protein called tubulin. This cytoskelton gives the cells their structure. One of the motor proteins Hank Green speaks […]

SciShow: what is energy?

Energy can be found everywhere and in many forms. In the same way as the existence of matter, energy as existed since the dawn of the Universe. It is a constant quantity in the Universe: nothing gets lost, but only transformed. Energy is the ability to do work and mass and energy are the same […]

Estivation, much like the hybernation, but for hot times and areas

Estivation is a process in which animals retain water and slow down metabolism in order to survive a hot dry season. Most of the animals that undergo estivation will cover themselves with a mucus that will keep them protected from warmth like a cocoon. Estivation can last from weeks, months to sometimes years in Australia […]

Hank Green, from SciShow, explains how researchers got the idea that an asteroid killed the dinosaurs 65 million years ago and why that is not the whole picture. It seems that the asteroid was the last drop in the bucket and that climate change, volcanic eruptions were the ones that started the extinction. The asteroid […]
