Zika birth defects: Concerns spread from head to toe
Zika infections may trigger problems well beyond babies born with small heads and brains. Scientists have begun linking a range of head-to-toe health ails to the virus.

Tasmanian devils begin to resist infectious cancer
A deadly contagious cancer is spreading among Tasmanian devils. But the animals are evolving resistance, a new study finds.

Scientists watch germs evolve into superbugs
To study how bacteria can evolve resistance to a wide variety of drugs, scientists spread the germs on a food-filled plate the size of a foosball table. Then, they watched resistance rise.

Bananas under attack: Understanding their foes
Fungal blights threaten the world’s most popular fruit. But genetic studies hint at new ways to combat some of these diseases.

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.

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.

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.

Cool Jobs: Pet science
Pets make great subjects for research. These scientists work to make our animals — and us — healthier and happier.

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.

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.
