Chinook make their way up the Klamath River every year, but fewer and fewer arrive in the spring.

Various concerned groups have been petitioning NOAA Fisheries to list spring-run Chinook salmon in Oregon and Northern California for over a decade.

With ever-advancing genetic technologies, researchers continue to document the genetic code of the human species.

When micronuclei rupture, chromosomes break, recombine, and form circles, causing inflammation and promoting carcinogenic growth.

Understanding this complex and still largely enigmatic process will pave the way for researchers to control the development of new morphologies.

The gene BCO2 enables male and female members of some bird species to display dramatically different color patterns.

When the nucleic acid spirals to the left, it takes on a zig-zag shape known as Z-DNA that appears to regulate RNA editing.

Integrating a specialized histone into large segments of transgenic DNA enables centromere formation.

A study on yeast illuminates how insertions may occur.

Editors’ picks of the year’s best in The Scientist infographics.

Fruit flies and mice grow better and eat less when the amino acid balance of their food reflects that coded by their exomes.

See how scientists designed food with amino acid compositions based on protein-coding regions in the genomes of mice and fruit flies.

See how two new methods track responses to unique genetic manipulations in numerous individual cells in parallel.

Eukaryotes prevent secondary RNA structures called G-quadruplexes, commonly observed in vitro, from forming in the cell. 

See how researchers visualize regions of active genes.

Scientists find fewer RNA G-quadruplexes in vivo than in vitro.

Traditional stop codons have a double meaning in the protozoans' mRNA, sometimes calling for an amino acid during translation.

Newly developed techniques from four different groups rely on the same basic steps to track translation in live cells.

Here’s how guide RNAs and the Cas9 enzyme work together to edit DNA.
