A mother mouse’s gut microbes help wire her pup’s brain
The pups of mice lacking gut microbes, and the compounds they make, have altered nerve cells in part of the brain and a lowered sensitivity to touch.

50 years ago, scientists were on the trail of a brain-eating amoeba
In 1970, scientists were studying a brain-eating amoeba that had been implicated in a newfound disease. Today, infections by the parasite are still poorly understood.

How does a crop’s environment shape a food’s smell and taste?
Scientific explorations of terroir — the soil, climate and orientation in which crops grow — hint at influences on flavors and aromas.

If bacteria band together, they can survive for years in space
Tiny clumps of bacteria can survive at least three years in outer space, raising the prospect of interplanetary travel by microbial life.

Scientists stumbled across the first known manganese-fueled bacteria
A jar left soaking in an office sink helped scientists answer a century-old question of whether bacteria can use manganese for energy.

Scientists want to build a Noah’s Ark for the human microbiome
Just as the Svalbard Global Seed Vault protects global crop diversity, the Microbiota Vault may one day protect the microbes on and in our bodies.

Earthy funk lures tiny creatures to eat and spread bacterial spores
Genes that cue spore growth also kick up a scent that draws in springtails.

Algae use flagella to trot, gallop and move with gaits all their own
Single-celled microalgae, with no brains, can coordinate their “limbs” into a trot or fancier gait.

Microbiologists took 12 years to grow a microbe tied to complex life’s origins
Years of lab work resulted in growing a type of archaea that might help scientists understand one of evolution’s giant leaps toward complexity.

How bacteria create flower art
Different types of microbes growing in lab dishes can push each other to make floral patterns.

Microbes slowed by one drug can rapidly develop resistance to another
Hunkering down in a dormant, tolerant state may make it easier for infectious bacteria to develop resistance to antibiotics.

Injecting a TB vaccine into the blood, not the skin, boosts its effectiveness
Giving a high dose of a tuberculosis vaccine intravenously, instead of under the skin, improved its ability to protect against the disease in monkeys.
