Scientists identify special pair of RNA scissors with many functions

CRISPR/Cas systems are known as promising "gene scissors" in the genome editing of plants, animals, and microorganisms by targeting specific regions in their DNA - and perhaps they can even be used to correct genetic defects.

Researchers solve crystal structure for enzyme that plays key role in DNA methylation

A research team led by a biochemist at the University of California, Riverside has solved the crystal structure for an enzyme that plays a key role in DNA methylation, the process by which methyl groups are added to the DNA molecule.

Study sheds light on Salmonella death at low temperatures

The most economical way to kill bacteria that cause common food-borne illnesses -- mostly caused by Salmonella enterica -- is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until now, according to a team of researchers.

Ribosomes found to be cause of somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria. Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Researchers discover specific taste neurons necessary for protein craving in fruit flies

A team of neuroscientists from the Champalimaud Centre for the Unknown, in Lisbon, Portugal, has discovered that were it not for specific taste neurons located in the fruit fly's proboscis (the equivalent of our tongue), the fly would not develop a craving for protein even when in excruciating need of it.

Free magnesium ions regulate chromosome shape, new tool shows

Japanese researchers report a new ion detector, MARIO. Using it, they show that changes in the intracellular concentration of free magnesium ions (Mg2+) is critical for the chromosome folding that must occur for cells to divide.

Small tweak to mammal's DNA can cause significant physical changes, study finds

The difference between webbed toes and distinct digits may be the result of not just genetic information, but of how the genes regulate that information. Researchers at the National Institute of Genetics, Research Organization of Information and Systems in Japan found that a small, non-specific tweak to a mammal's DNA can potentially cause specific and significant physical changes.
