Scientists Say: DNA sequencing
All of us have our own individual DNA. Now, scientists can determine what each individual strand is made of — a process called DNA sequencing.

GM mosquitoes cut rate of viral disease in Brazil
Adults males carrying the altered gene cannot father young that survive to adulthood. That’s when they suck blood — and can transmit disease.

How a moth went to the dark side
Peppered moths and some butterflies are icons of evolution. Now scientists have found a gene responsible for making them so.

The turning of wolves into dogs may have occurred twice
The process of turning wolves into dogs, called domestication, may have occurred twice — in the East and the West — ancient DNA suggest.

Why some frogs can survive killer fungal disease
A disease is wiping out amphibian species around the globe. New research shows how some frogs develop immunity.

Pacific islanders got a double dose of Stone Age DNA
Unlike other people, certain Pacific Islanders inherited DNA from two ancient human ‘cousins.’

Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.

Fattier yeast live long and prosper
Scientists were hoping to build better biofuels. Instead they discovered that fatter yeast cells live longer than lean ones.

Neandertal toe contains human DNA
DNA from a 50,000-year-old Neandertal woman’s toe bone shows humans left a mark on the ancient species — and much earlier than scientists had thought.

Vaping may threaten brain, immunity and more
New studies of e-cigarette vapor in animals and human cells find new risks to gene activity, behavior and male sperm.

Behavior of genes could identify type of infection
The behavior of hundreds of genes can identify a viral infection, a new study finds. That could help doctors determine treatment for a sick patient.

Scientists Say: Mutation
Information in an organism is stored in a code. Here’s the word scientists use to describe a change in that code.
