Predicting the effects of changes on living systems

Can scientists predict what happens when they introduce a change into a living system—for example, if they change the structure of a gene or administer a drug? Just as changing one letter can completely change the meaning ...

Mutation breaks HIV's resistance to drugs

The human immunodeficiency virus (HIV) can contain dozens of different mutations, called polymorphisms. In a recent study an international team of researchers, including MU scientists, found that one of those mutations, called ...

Insights into primate diversity: Lessons from the rhesus macaque

New research published in BMC Genetics shows that the rhesus macaque has three times as much genetic variation than humans. However despite much of this extra variation being within genes, it does not affect protein function. ...

In cod we trust: DNA test combats fisheries fraud

Scientists on Tuesday said they had devised a DNA test to pinpoint the geographical origins of commercial seafish, in a breakthrough against illegal trawling that threatens fish stocks worldwide.

Bird color variations speed up evolution: research

Researchers have found that bird species with multiple plumage colour forms within in the same population, evolve into new species faster than those with only one colour form, confirming a 60 year-old evolution theory.

Study spotlights dog impulsivity

Researchers in Hungary have discovered a clear link between repeat polymorphism in the tyrosine hydroxylase (TH) gene with activity-impulsivity in German Shepherd dogs. The research is presented in the journal PLoS ONE.

Largest rice genetics study finds vast differences in rice

The largest publicly available genomewide association mapping study in rice to date has found that although the five subpopulations of Asian rice -- indica, aus, temperate japonica, aromatic and tropical japonica -- all belong ...

Genomic tools can help researchers develop crops quickly

(PhysOrg.com) -- Using powerful genome sequencing tools created for human genetics, researchers can now exploit the genetic diversity of crops to improve productivity, sustainability and nutrition, a Cornell researcher reported ...

Bringing better grapes a step closer to reality

Grapes are one of the world's most economically important fruit crops, but the woody perennial takes three years to go from seed to fruit, and that makes traditional breeding expensive and time-consuming.
