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.

Gene editing swats at mosquitoes
A new genetic technique can render insects that spread malaria unable to reproduce.

New gene resists our last-ditch drug
Antibiotic resistance continues to grow. Now, scientists have found a tiny loop of DNA that resists a drug doctors use as a last line of defense.

Expert panel approves human gene editing
Scientists have recently been reporting big advances in the ability to tweak the genes of living organisms, including people. But some question the ethics of doing that. A panel of experts now says such research can go ahead — with one major exception.

Banana threat: Attack of the clones
Researchers find that disease-causing fungi — all clones of one another — will continue to infect banana plants unless new steps are taken to stop their spread.

Taking attendance with eDNA
Environmental DNA, or eDNA, tells biologists what species are in an area — even when they’re out of sight.

Wildlife forensics turns to eDNA
Environmental DNA, or eDNA, tells biologists what species have been around — even when they’re out of sight or have temporarily moved on.

Gene editing creates buff beagles
Scientists showed that a potentially useful new gene-editing tool can work in dogs. It created a pair of adorable, muscular puppies. But the goal is to use it for other research purposes.

The earliest evidence of plague
Plague is best known as the killer disease that wiped out nearly half of Europe during the 1300s. But the germ infected people up to 3,000 years earlier than that, DNA from ancient teeth now show.

Trio gets chemistry Nobel for figuring out DNA repair
Three researchers have won the 2015 Nobel Prize in chemistry for working out how cells fix damaged genetic material.

Plant ‘vampires’ lay in wait
A new study shows how some parasitic plants evolved the ability to sense a potential host — and then send out root-like structures to feed on them.
