Cones cells, located in the centre of the retina (in an area called the macula), are not much good...

The mice were blind – they had no rods and cones cells left, but their body clocks were working okay. This lead to the discovery of a previously unknown light receptor cell in the eye: containing...

Only the retina is light sensitive, and it is roughly the area of a 10p...

He was cross breeding garden peas and observing the characteristics of the resulting plants and the peas produced from the parent plants. He observed dominance and segregation. Inheritance worked in numerical ratios and...

The light waves are refracted (bent) as they enter and leave the prism. The shorter the wavelength of the light the more it is refracted, so...

Was there more than one origin? When did organic chemistry become biology i.e., life, a process called abiogenesis? Chemistry based on carbon is incredibly varied and can be extremely complex, it is thought that at some point under...
