MUTATION
Top ‘mutation’ Contributors
Take Bird Flu Seriously
News from the world Health Organisation that the bird flu mutated amongst the largest known human cluster is very disturbing. It’s really only a matter of time before this virus can easily jump from human to human. When that happens I really fear for the human race.
A new kind of mutation could explain numerous phenotypic variations in various species

It appears, therefore, that this new kind of mutation, discovered while studying sheep, could contribute significantly to the phenotypic variation observed in many species – among which humans – including the hereditary predisposition to various diseases.
Is evolution predictable? Finding microbes' adaptation algorithms

"Associate professor Yousif Shamoo and two students recently conducted experiments on a microbe, G. stearothermophilus, to see how it adapted to different environmental circumstances.
Evolution happens faster in the tropics

The biodiversity of the planet is not spread out evenly; it is highest in the tropics, and lowest at the poles.
Environmental DNA damage may drive human mutation

"Mutations drive evolution. Subtle changes in the pairing of the chemical letters of DNA--adenine, cytosine, guanine and thymine--produce new cells with different traits than their ancestors.
Scientists: Bird flu too deep in lungs to spread

Scientists say they have found a reason bird flu is not spreading easily from person to person: The virus concentrates itself too deep in the respiratory tract to be spewed out by coughing and sneezing.
Controversial findings help explain evolution of life

Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation – an idea that has challenged some of the most basic concept
Renowned Bird Flu Expert Warns: Be Prepared

Robert G. Webster is one of the few bird flu experts confident enough to answer the key question: Will the avian flu switch from posing a terrible hazard to birds to becoming a real threat to humans?
Genetic Mutation Linked To West Nile Virus Infection

A genetic mutation that protects against HIV increases the risk of developing clinical West Nile Virus infection, according to a new study appearing online on January 9th in The Journal of Experimental Medicine.
Tick, Tock: Humans Have a Slow Molecular Clock
