Cattle are a major driver of methane emissions.

Why Do Cows Burp Up So Much Planet-Warming Methane? A Newly Discovered Structure in Their Gut Microbes Could Be a Culprit

The “hydrogenobody” is an organelle inside certain microorganisms that live in a special stomach chamber in cattle, sheep and goats, according to a new study

Courses of the antibiotic clindamycin taken within a year before stool sampling were associated with the largest changes in gut microbiomes.

Some Antibiotic Drugs Can Alter Your Gut Microbiome for Up to Eight Years, New Research Suggests

Just a single course of treatment can leave a lasting impression, according to a study of nearly 15,000 people in Sweden

Researchers developed a tiny fart-measuring device that snaps into underwear. 

How Often Do You Fart? This ‘Smart Underwear’ Can Keep Track, Because Figuring Out a Baseline Is Important for Science

Researchers have launched a study to find a typical range for flatulence, which has been harder to measure than you might expect

 Maria Branyas Morera on her 117th birthday

Scientists Studied the Genes of a Woman Who Lived 117 Years. Here’s What They Learned

Maria Branyas Morera, formerly the world’s oldest person, allowed researchers to take a detailed look at her biology before she died last year

Researchers studied genetic samples from 483 mammoths, including from their tusks, bones, skin and molars (shown here).

Scientists Investigate the Bacteria That Colonized Extinct Mammoths—and Uncover the Oldest Known Microbial DNA From a Host

Some of the microbes might have been benign or helpful, while others could have caused deadly diseases

Demonstrators in Berlin last year advocated for increased awareness of ME/CFS.

Scientists Find Links to Chronic Fatigue Syndrome in Genes and in the Gut Microbiome

Two studies present new data on ME/CFS, offering “credibility and validity” to the experiences of patients struggling with symptoms

Microbes can grow in clouds and even divide in two.

A Brief and Amazing History of Our Search for Life in the Clouds

By collecting samples after climbing a high peak and firing rockets with special traps into the upper atmosphere, scientists have found microbes living in thin air

An artistic representation of microorganisms. New research suggests sex may transfer a distinctive microbiome to a person's partner.

Couples Exchange Bacteria During Intercourse, Known as the ‘Sexome.’ It Might Help Track Down Sexual Assault Perpetrators

In a study of 12 heterosexual couples, researchers noted the presence of a partner’s genital bacteria after sex, even when the pair used a condom

A petri dish with bacteria from a stool sample. The researchers found a number of bacteria, fungi and viruses in fecal samples from children that were altered in children with autism.

Gut Microbes Could Help Diagnose Autism, Study Suggests

While more research is needed, scientists detected specific differences between the gut microbiomes of children with and without autism

In 1881, Fanny Angelina Hesse suggested agar, a jelly-like substance she used in cooking, as a replacement for gelatin, which scientists used to study microorganisms.

Women Who Shaped History

Meet the Forgotten Woman Who Revolutionized Microbiology With a Simple Kitchen Staple

Fanny Angelina Hesse introduced agar to the life sciences in 1881. A trove of unpublished family papers sheds new light on her many accomplishments

Caecilian mothers grow a fatty layer of skin that their babies tear off with specialized teeth and eat.

This Worm-Like Amphibian Eats Its Mother’s Skin to Get Microbes

Caecilians are the only known amphibians to pass microbes from one generation to the next, according to a new study

A coral reef in Honolulu, Hawaii. Half of global coral coverage has disappeared since the 1950s.

Coral Reefs Host a Vast Diversity of Microbes

A two-year expedition at sea uncovered more than half a million varieties of microbial life in Pacific reef-dwelling organisms

Seabirds catch fish swimming near the ocean's surface, but in the process, they also ingest microplastics.

Microplastics Linked to Changes in Seabirds’ Guts

Birds that ingested more microplastics had more microbes linked to diseases and antibiotic resistance in a new study

Technician Yesmarie De La Flor prepares cultures of probiotics in the Smithsonian Marine Station’s microbiology laboratory in Fort Pierce, Florida. These probiotics were used for testing on diseased corals.

Probiotics May Help Corals Fight a Dangerous Disease Off Florida’s Coast

The new treatment shows promise in lab experiments

Gut bacteria, more than genetics, impact mice's motivation to exercise, a recent study suggests.

Could Gut Bacteria Impact Your Motivation to Exercise?

In a study of mice, researchers show their microbiomes play a role in how much they run and how quickly they grow fatigued

A group of zebrafish

Gut Bacteria Might Shape Social Behavior

A study of zebrafish reveals the mix of microbes in the intestinal tract could influence brain development

Four pairs of "human doubles" included in the study

Art Meets Science

Doppelgängers Don’t Just Look Alike—They Also Share DNA

New research finds genetic and lifestyle similarities between unrelated pairs of “virtual twins”

Contrary to researchers' expectations, cats with higher levels of the hormone oxytocin displayed fewer bonding behaviors than those with lower levels. 

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior

Felines with lower cortisol, oxytocin and testosterone levels are more tolerant of other cats

To make true Roquefort cheese, the law requires that it must be produced from local ingredients and ripen for months in a cave in southern France. 

How Much Longer Will Roquefort Reign as the King of Cheese?

In France, makers of the odorous food are singing the blues

To get the award-winning shot, Fabian J. Weston, used a microscope from the 1970s and went as far as creating a saline solution that would keep the micro-fauna alive while imaged.
