Did we just discover what dark matter is made of? Maybe sterile neutrinos are the solution!

DNews reports that sterile neutrinos could be the candidates for dark matter. Those are neutrinos that have masses between the electron neutrino (0.3 eV) and muon neutrino (0.115 MeV). In fact, it seems that the sterile neutrino might have a mass of just about 3.55 keV as it gives off X rays in that band […]

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 […]

Watch these incredible animated optical illusions by Brusspup

Brusspup is the master of optical illusions on YouTube. Many videos will show you how the brain is tricked in numerous ways. In this case you can see how two sliding sheets will generate the illusion of movement. Much the same as with early cartoons where you saw a ton of still images on a […]

You wont believe: the smallest possible star is just a bit bigger than Jupiter

It is said that Jupiter is a failed star. It is so massive that, if it were a couple of times more massive, it would have become a star. Stars can be way smaller than our Sun. For example, theoretically, a red dwarf star has only about 7.5% the mass of the Sun. Poxima Centauri, […]
