April Flowers for redOrbit.com - Your Universe Online A half liter of seawater can contain evidence of local fish and whale faunas and combat traditional fishing methods, says a new study from the University of Copenhagen. Researchers there have created a new way for monitoring marine biodiversity and resources by using DNA traces in seawater samples. The results of this study are now published in the journal PLoS ONE. "The new DNA-method means that we can keep better track of life...

A broken chromosome is like an unmoored beansprout circling in search of attachment. If a cell tries to replicate itself with broken chromosomes, the cell will be killed and so it would very much like to find its lost end. Often, it finds a workable substitute: another nearby chromosome. When a broken chromosome attaches to another, or when chromosomes use a similar process to exchange genetic material, you have a translocation — genes end up fused to other genes, encoding a new...

A Look At The Early Evolution Of Sex Chromosomes

Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings are described in two papers in the Proceedings of the National Academy of Sciences. The research reveals that the papaya sex chromosomes have undergone dramatic changes in their short evolutionary histories (they are about 7 million years old; by comparison, human sex chromosomes...
