Scientists Say: Infection
Infections range from mild illnesses, such as the common cold, to deadly diseases, such as rabies.

Bacterial ‘living wires’ could help protect the seas and climate
Long, thin bacteria that conduct electricity may be able to help clean up oil spills and reduce emissions of methane, a powerful greenhouse gas.

How wriggling, blood-eating parasitic worms alter the body
Parasitic worms eat blood and make people sick, but they may also help prevent or treat some diseases.

This giant bacterium lives up to its name
The newly discovered Thiomargarita magnifica is about the size of your eyelash and is surprisingly complex.

Kitchen sponges are bacteria’s dream home
Sponges are favorite spots for bacteria, partly because of the mixed-housing environment that the cleaner-uppers offer microbes.

Explainer: The body’s immune system
An army of cells — and their protein arsenal — work to keep us safe. Several squads of special forces possess unique superpowers to disable or kill intruders.

Recycling a climate-warming gas could make ‘greener’ farmed fish
Instead of warming the climate, methane gas can be collected to help farmers. Along the way, it may also save some fish.
- Microbes
Scientists Say: Bacteria
Bacteria get a bad rap for making people sick, but only a tiny portion of these single-celled creatures cause disease.

Analyze This: This material for 3-D printing is made by microbes
Bacteria with tweaked genes pump out proteins that can be used in a 3-D printer. With microbes in the mix, the living ink can make drugs or suck up chemicals.

Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.

Meat-eating bees have something in common with vultures
Flesh-eating bees have acid-producing gut bacteria, much as vultures do. It lets them safely snack on rotting meat.

Bacteria make ‘spider silk’ that’s stronger than steel
Part spider silk, the material is better than what some spiders make. Researchers think it might make the basis for surgical threads or unusually strong fabrics.
