Bacteria do many useful jobs almost everywhere on Earth, from the soil to the seafloor to our stomachs.
Microscopic fossils from Australia suggest that some bacteria evolved structures for oxygen-producing photosynthesis by 1.78 billion years ago.
Unified by a few key traits, these diverse organisms come in all shapes and sizes.
If made under gentle conditions, leather formed from the “roots” of mushrooms can retain the ability to regrow and repair minor damage.
A new device can detect from seven to 35 coronavirus particles per liter of air in minutes. That’s close to a PCR test’s sensitivity — but much quicker.
Hot-air hand dryers are a haven for microbes. A finalist at Regeneron ISEF found that these machines spray germs all over freshly washed hands.
A virus must take over a living cell's machinery to make more viruses.
Some algae glow blue when they experience forces. Held in transparent plastic, they now make devices light up in response to gentle pushes and tugs.
Linking types of bacteria to specific flavors could help cheesemakers tweak their products — or even develop new cheese flavor.
