— It is not a sci-fi that humans can nurture meat like vegetables.

Scientists at Oxford University’s Wildlife Conservation Research Unit are researching in-vitro meat–burgers or sausages grown in laboratory Petri dishes rather than made from livestock, according to a Reuters report last week.

They are nurturing stem cells got from leftover livestock meat from slaughterhouses. To make them grow up to meat, Mark Post, one of the researchers in the project, said they feed the stem cells with sugars, amino acids, lipids, minerals and all other necessary nutrients.

By now, pale muscle-like strips have been produced. But each strip, 2.5 cm long and less than a centimeter wide, is hardly seen with naked eyes.
