Scientists identify new virus-killing protein

A new protein called KHNYN has been identified as a missing piece in a natural antiviral system that kills viruses by targeting a specific pattern in viral genomes, according to new findings published today in eLife. Studying ...

Moulds produce plant growth hormone

Plants, bacteria and various fungi produce a specific group of hormones known as auxins. Together with other hormones, they cause plant cells to stretch and thus, for example, the rapid growth of young shoots. The manner ...

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 ...

Embryos rapidly outgrow mother's genetic kick-start

Attaining independence from one's parents is an enduring theme in the lives of many organisms. Birds must fly the nest, just as mammals must wean off their mother's milk.

DNA research offers clues on cell mutation

A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly ...

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 ...

Damaged DNA amplified

For the first time, researchers have succeeded in amplifying genes altered by activities such as smoking—with changes that can lead to lung cancer. As the amplified genes retain the altered information, this marks an important ...

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, ...
