A few rare viruses can reach the fetus when pregnant women are infected, with tragic result. As explored in this Q&A, researchers are figuring out how the placenta acts as protector and how some pathogens slip through.
How do trees find their sense of direction as they grow? Researchers are getting to the root — and the branches — of how the grandest of plants develop.
Ultrasound isn’t just for images. Sonogenetics and other promising technologies let researchers use focused sound waves to control genes and entire cells deep in the tissues of living animals, without surgery.
Epidemics of forest-felling diseases are on the rise thanks to globetrotting pathogens that slip through even the best defenses. To prevent further losses, scientists are turning to high-tech surveillance and detection, even canine noses.
Carnivorous plants fascinate as much now as when their gruesome diet was first discovered. Molecular biology is helping botanists trace the origins of their predatory ways.
Millions of years of coevolution have given the insects a bag of tricks to escape their predators — from signal-jamming and decoys to acoustic camouflage
From monkeys washing potatoes to cockatoos raiding trash cans, socially spread behaviors allow creatures to adapt more rapidly to changing environments than conventional evolution would allow. But the traits are also more easily lost.
