Photosynthesizing Bacteria Found Thriving Thousands of Feet Below Earth's Surface Photosynthesizing Bacteria Found Thriving Thousands of Feet Below Earth's Surface

An international team of researchers has identified a peculiar population of cyanobacteria living within rocks deep below Earth’s surface—a surprising discovery given that cyanobacteria require sunlight to survive. Or so scientists thought.

Scientists Peer Inside the Disgusting Cloud of Living Things That Surrounds You Daily Scientists Peer Inside the Disgusting Cloud of Living Things That Surrounds You Daily

From the minute we’re born, we’re surrounded by a swarm of things not visible to the human eye—dangerous pathogens, harmless microbes, and a wide assortment of chemicals. A new study out of Stanford University seems to illuminate this hidden world, and the results are admittedly both cool and terrifying.

A Common Antidepressant Might Help Bacteria Become Superbugs A Common Antidepressant Might Help Bacteria Become Superbugs

A common antidepressant, sold under the brand name Prozac, could be helping some bacteria build resistance to antibiotics, suggests a new study from Australia. The study, published in Environment International, found that fluoxetine was capable of inducing antibiotic resistance in laboratory strains of Escherichia coli…

Jet Hand Dryers Are Basically Germ Cannons, Study Finds Jet Hand Dryers Are Basically Germ Cannons, Study Finds

It’s long been suspected that hand dryers, especially those quick-drying ones that blast hot air known as jet dryers, are actually way worse at keeping our hands and bathrooms free of disease-causing germs. Worryingly, they could even be spreading illness in hospital bathrooms, new research suggests.

Scientists created this picture of the Mona Lisa using genetically modified E. coli bacteria. Such teeny little artists!

Probiotic Supplements Might Be Giving Some People 'Brain Fog' Probiotic Supplements Might Be Giving Some People 'Brain Fog'

Given their current popularity, you might assume that probiotics—capsules containing a mix of “good” bacteria that are said to rebalance our gut’s bacterial content—would be perfectly harmless. But a team of gastroenterologists from Augusta University in Georgia is challenging that assumption. Their recent study is…

Hong Kong Subway Study Shows How Quickly Bacteria Travel Across a City Hong Kong Subway Study Shows How Quickly Bacteria Travel Across a City

If you’re one of the billions of people worldwide to use mass public transit regularly, you’re sharing a lot more than a commute with your fellow passengers, suggests a new study published Tuesday in Cell Reports. You’re also sharing and swapping the teeming microbes that call our bodies home.

Can You Get a Disease From a Toilet Seat? Can You Get a Disease From a Toilet Seat?

The world is filled with disgusting toilets. You might personally prefer toilets that smell okay and aren’t covered in filth, but try telling that to whichever organs are involved in making you really need to use the bathroom. It has happened before, and it will happen again: you’ll be at a public bus station, or a…

Chimp Beds Are Way Less Filthy Than Human Beds Chimp Beds Are Way Less Filthy Than Human Beds

In a twist that rivals cinema’s best, a new study published Tuesday in Royal Society Open Science suggests a horrible truth: We’ve been the damn dirty apes all along. It found that beds made by one of our closest primate relatives, chimpanzees, contain little personal filth, meaning germs and parasites from their own…

There's Life on the Closest Thing We Have to Mars There's Life on the Closest Thing We Have to Mars

A new study has documented for the first time how certain microorganisms are able to survive the extreme aridity of Chile’s Atacama Desert—the world’s driest—by going dormant for decades.

Humans, Not Rats, May Have Been Responsible for Spreading the Black Death Humans, Not Rats, May Have Been Responsible for Spreading the Black Death

The Black Death, a plague responsible for killing around a third of the population of Europe during the 14th century, spread to millions of humans by rats that carried infected fleas—right? That’s the story we’ve long been told by historians. A new study upends this conventional thinking, showing that humans, and not…

Stop Feeding Your Pets Raw Meat Stop Feeding Your Pets Raw Meat

An emerging trend among pet owners is the practice of feeding dogs and cats raw meat. This idea is that we should put our domestic cats and dogs on diets that more closely approximate what they might eat in nature. New research from Europe shows the surprising degree to which germs and parasites can be found in…

A New Type of Steel Kills Bacteria With Nanospikes A New Type of Steel Kills Bacteria With Nanospikes

In an age when bacteria are becoming increasingly resistant to our best antibiotics and the words “E. coli” can shut down your favorite local Chipotle, people are desperate for anything that promises to wipe out germs. Unfortunately, when it comes to cleaning products that label themselves “antimicrobial,” they’re…

Scientists Added Two New Letters to DNA's Code Scientists Added Two New Letters to DNA's Code

If you’ve taken a science class, you’re likely aware that DNA is the body’s instruction manual. But its language is only written in four letters: A, T, C, and G. Those who paid extra close attention will remember that RNA, the photocopy of the instructions that the cell actually uses, replaces the Ts with the letter…

Yep, It's Still Not a Good Idea to Eat Raw Cookie Dough Yep, It's Still Not a Good Idea to Eat Raw Cookie Dough

For some, sneaking a mouthful of raw cookie dough while baking is an indelible—and certainly delicious—part of the process. But while we’ve been told to avoid dough containing raw eggs, a new investigation confirms that tainted raw flour was responsible for an E. coli outbreak in 2016—a finding that will surely test…

Flooding breached dozens of waste treatment centers, sending a deluge of bacteria throughout the city. The New York Times reports on the victims of the bacterial…

Alarming Study Indicates Why Certain Bacteria Are More Resistant to Drugs in Space Alarming Study Indicates Why Certain Bacteria Are More Resistant to Drugs in Space

To learn more about why some germs seem harder to kill in near-weightless conditions, scientists aboard the ISS recently doused a batch of bacteria with antibiotics—an experiment which resulted in a series of startling physical changes that may be helping the bacteria to survive and thrive in space.
