Bacteria in Brains Suggest Alzheimer’s-Gum Disease Link

Bacteria linked to gum disease traveled to the brains of people with Alzheimer’s disease, suggesting that dental hygiene plays a role in the development of the memory-robbing illness, British researchers said.

Signs of the bacterium, known as Porphyromonas gingivalis, were found in four out o... Read More

Social amoebae travel with a posse: Tiny single-celled organisms have amazingly complicated social lives

In 2011, Nature announced that scientists had discovered a single-celled organism that is a primitive farmer. The organism, a social amoeba called Dictyostelium discoideum, picks up edible bacteria, carries them to new locations and harvests them like crops.

D. discoideum enjoyed a brief spel... Read More

More on ‘Nightmare Bacteria’: Maybe Even Worse Than We Thought?

In my last post I talked about the under-appreciated emergence of “nightmare bacteria” (those are the Centers for Disease Control and Prevention’s words, not mine) that are widely distributed in hospitals and nursing homes around the world and do not respond to a last-ditch small family of antib...

How Eating the Right Bacteria Could Give Your Body Superpowers

No man is an island. If anything, every man is a sentient, mobile farm for the countless quadrillions of bacteria that colonize us. And by introducing the right bacteria into that equation, you can give your body one heck of a boost.

Every person on this planet could reasonably be considered ... Read More

In the deep, bioluminescent bacteria bloom bright

Imagine swimming to the bottom of the sea, the water growing impossibly deep and dark the farther you travel. At these depths, beyond the reach of the sun, live strange new sources of light. Fish, jellyfish, and even bacteria light up these midnight waters.

According to new research in PLOS O... Read More

Fungal biology: Finding yeast's better half

Scientists long believed that the fungal pathogen Candida albicans was incapable of producing haploid cells—which contain only one copy of each chromosome, analagous to eggs and sperm—for mating. Mixing of genes in sexual reproduction helps generate the diversity that is the raw material for evo... Read More

Microbiome research goes without a home

Trillions of microorganisms call the human body home. But ‘home’ for many US scientists studying these microscopic squatters is about to change, as funding for human microbiome research scatters across 16 of the 27 centres of the US National Institutes of Health (NIH).

Last year, researchers ... Read More
