Sequencing hundreds of chloroplast genomes now possible

Researchers at the University of Florida and Oberlin College have developed a sequencing method that will allow potentially hundreds of plant chloroplast genomes to be sequenced at once, facilitating studies of molecular ...

'Rhythm' of protein folding encoded in RNA, biologists find

(Phys.org)—Multiple RNA sequences can code for the same amino acid, but differences in their respective "optimality" slow or accelerate protein translation. Stanford biologists find optimal and non-optimal codons are consistently ...

Tiny invention may harness big energy from small spores

(Phys.org)—One of Ozgur Sahin's first machines was a mechanical adding device made from Legos. He made it when he was 11 and hasn't stopped making gadgets since. In graduate school Sahin created an atomic force microscope ...

Process that controls tomato ripening discovered

(Phys.org)—Everyone loves a juicy, perfectly ripened tomato, and scientists have long sought ways to control the ripening process to improve fruit quality and prevent spoilage.

Scientists shed light on the 'dark matter' of DNA

In each cell, thousands of regulatory regions control which genes are active at any time. Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna have developed a method that reliably detects these regions ...

Rare form of active 'jumping genes' found in mammals

Much of the DNA that makes up our genomes can be traced back to strange rogue sequences known as transposable elements, or jumping genes, which are largely idle in mammals. But Johns Hopkins researchers report they have identified ...
