What Turned This Woman's Pee a Striking Shade of Lilac?
A woman who was hospitalized after having a stroke surprised doctors when, 10 days after being admitted, her pee turned purple. Turns out, an unusual chemical reaction can transform urine from its usual yellow to a striking lilac. The bizarre phenomenon, described in a case report published today (Oct. 30)...

Case of 'Rat Bite Fever' Reminds Us That Even Pet Rats Carry Loads of Diseases
Here's reason No. 1,001 that you shouldn't get too cozy with rats: Even the most adorable of them are still potential disease vectors. That's the takeaway from a newly reported case of a woman who developed rat bite fever, a potentially fatal disease, after being bitten by her pet rat....

Bacteria hiding in indoor dust could spread antibiotic resistance
Bacteria enter our homes, gyms and workspaces by hitching rides on our skin or blowing in through an open door. Once inside, these invader microbes might help indoor germs in the surrounding dust become resistant to antibiotics, a new study suggests. Antibiotic medications work by disrupting the inner workings of...
Sleeping microbes wake up after 100 million years buried under the seafloor

Sleeping microbes wake up after 100 million years buried under the seafloor
Microbes found themselves buried in the dirt 101.5 million years ago, back before even Tyrannosaurus rex when Earth’s biggest meat-eating dinosaur, called Spinosaurus roamed the planet. Time passed, continents shifted, oceans rose and fell, great apes emerged, and eventually human beings evolved with the curiosity and skills to dig up...
Scientists find 'secret molecule' that allows bacteria to exhale electricity

Scientists find 'secret molecule' that allows bacteria to exhale electricity
For mouthless, lungless bacteria, breathing is a bit more complicated than it is for humans. We inhale oxygen and exhale carbon dioxide; Geobacter — a ubiquitous, groundwater-dwelling genus of bacteria — swallow up organic waste and exhale electrons, generating a tiny electric current in the process. Those waste electrons always...

Live Science podcast 'Life's Little Mysteries' Episode 49: Mysterious Bacteria
In this episode of Life's Little Mysteries, we'll take a closer look at the mysterious single-cell microbes that are simpler than most other organisms, yet are still intriguingly complex: bacteria. What are bacteria and what do they look like? How long have bacteria been around? How do scientists study bacteria,...
What is the difference between prokaryotic and eukaryotic cells?

What is the difference between prokaryotic and eukaryotic cells?
The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the...
What are protists?

What are protists?
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12. Protists are eukaryotes as they possess a nucleus and other membrane-bound...

Biggest bacterium ever discovered amazes scientists with its complexity
Scientists discovered an absolutely massive bacterium that can be seen without the aid of a microscope and lurks among the mangroves of Grande-Terre in the Caribbean, Science magazine reported. The single-celled organism can grow up to 0.78 inches (2 centimeters) long and resembles a thin string, according to a report...

What is an amoeba?
Amoeba is a term that describes a simple eukaryotic organism that moves in a characteristic crawling fashion. However, a comparison of the genetic content of the various amoebas shows that these organisms are not necessarily closely related to each other. What does an amoeba look like?All living organisms can be...

8 ancient 'zombie viruses' that scientists have pulled from the melting permafrost
Locked away in frigid Arctic soils and riverbeds is a world teeming with ancient microbes. Bacteria and viruses that existed thousands of years ago are frozen in time inside prehistoric layers of permafrost. Warming temperatures could cause much of the ice to melt and unleash these microbes from their frosty...

Primordial steroids solve long-standing mystery about how the 1st complex life-forms evolved
Steroids discovered in 1.6 billion-year-old rock may help scientists solve a long-standing mystery about the evolution of single-celled life. These compounds are produced by eukaryotic organisms, which are defined by having cells with nuclei and interior organelles bound by membranes. Modern eukaryotes include plants, fungi and animals. In contrast, prokaryotes...

Bizarre giant viruses with tubular tentacles and star-like shells discovered in New England forest
Giant viruses lurking in the soils of a New England forest sport traits never seen in other viruses of similar heft — from star-like outer shells to bizarre, tubular appendages, according to a preprint study published in bioRxiv. What we found is a whole new diversity of shapes that we...

After you die, your microbiome cooperates with soil microbes to 'recycle' your body
Each human body contains a complex community of trillions of microorganisms that are important for your health while you’re alive. These microbial symbionts help you digest food, produce essential vitamins, protect you from infection and serve many other critical functions. In turn, the microbes, which are mostly concentrated in your...
