Re-cracking the genetic code

Crack open a biology textbook and you will find the table summarizing the standard genetic code. This refers to the set of rules by which the cell "decodes" the information contained in DNA and "translates" it into the amino ...

Genomic fluke close-up

Parasitic flukes have been a leading source of food-borne infections, sparking fear and wreaking havoc on human public health, and contributed to more than 3 billion in animal agricultural losses per year in the U.S. alone.

Improved mapping of Swedish genes from 1,000 individuals

People—or more specifically just Swedes—are more like chimpanzees than previously known. This is indicated in a genetic mapping of one thousand Swedish individuals, where new DNA sequences that should be included in the ...

Extinction of Icelandic walrus coincides with Norse settlement

An international collaboration of scientists in Iceland, Denmark and the Netherlands has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus ...

Rapid evolution: New findings on its molecular mechanisms

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed that geographical barriers ...
