Expanding DNA's alphabet lets cells produce novel proteins

Scientists are expanding the genetic code of life, using man-made DNA to create a semi-synthetic strain of bacteria—and new research shows those altered microbes actually worked to produce proteins unlike those found in ...

Biologists create beetle with functional extra eye

On "Game of Thrones," a three-eyed raven holds the secrets of the past, present and future in a vast fantasy kingdom. But for real-world biologists, a "three-eyed beetle" may offer a true glimpse into the future of studying ...

New evidence emerges on the origins of life

In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing ...

World's first artificial enzymes created using synthetic biology

(Phys.org)—Medical Research Council (MRC) scientists have created the world's first enzymes made from artificial genetic material. Their synthetic enzymes, which are made from molecules that do not occur anywhere in nature, ...

A complex logic circuit made from bacterial genes

(Phys.org)—By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to ...

Model suggests how life's code emerged from primordial soup

(PhysOrg.com) -- In 1953, Stanley Miller filled two flasks with chemicals assumed to be present on the primitive Earth, connected the flasks with rubber tubes and introduced some electrical sparks as a stand-in for lightning. ...

The 'Rapunzel' virus: An evolutionary oddity

A recent study in the Journal of Biological Chemistry has revealed the secret behind an evolutionary marvel: a bacteriophage with an extremely long tail. This extraordinary tail is part of a bacteriophage that lives in inhospitable ...
