Bacteria Sometimes Catch A Virus
Bacteria sometimes catch a virus. Bacteriophages--'bacteria-eaters'-- or phages, are viruses that use bacteria to multiply. The phage attaches to a bacterium, injects its own genetic material, either ... Continue reading
Embryo Transfer and Cloning
Scientists use embryo transfer technology to obtain more offspring from a genetically superior animal. For instance, if a farmer owns a cow that produces excellent milk and wants more cows to produce ... Continue reading
Cloning and Ethics
Cloning technology today is far from perfect: it requires many attempts and only 1%, if any, of the cloned eggs become embryos and then survive. For example, the first cloned sheep, Dolly, was ... Continue reading
Jumping Starlight
'Twinkle, twinkle, little star, how I wonder what you are,' says the song by Jane Taylor. But stars don’t really twinkle; their light reaches the earth in a steady way. Why then do we see them ... Continue reading
Genetic Testing And Discrimination
Genetic testing is the use of recombinant DNA technology to obtain information about a person's genome. The first genetic tests were conducted during the 1960s for the disease phenylketonuria (PKU). ... Continue reading
The Incredible Capacity Of The Immune System
By age two, infants in the US can receive up to 20 vaccinations. In view of that, concerns had been raised that too many immunizations could overwhelm an infant's immune system. ... Continue reading
