On the benefits of 'fart walks'

Scientists seeking gut insights are attaching flatulence sensors to volunteers' underwear

This fart-tracking device detects gas generated in the gut, providing insights about gut microbial activity. The underwear sensors measure a component of what is technically called flatus—digestive system gas.

Even brief physical activity can trigger the release of neurotransmitters that provide mental health boosts

A couple of minutes of light walking or stretching can increase feelings of energy and reduce fatigue, not just through the release of endorphins. Exercise can also provide self-regulation and improve task engagement and focus in those with certain mental health disorders, like ADHD.

Exercise causes diet-independent changes in the gut microbiome

Vitamin B1 is linked to gut motility—helping fight constipation—in 2026 research

A study published in early 2026 found a link between vitamin B1 and the successful movement of food through your GI tract, known as gut motility. The work incorporated genetic and survey data about poop frequency to identify genes associated with gut motility and then separately linked poop frequency data with how much vitamin B1 people ingested, theorizing that the vitamin supports the production of acetylcholine, a neurotransmitter that stimulates GI system contractions.

There's an official term for the sound your stomach makes before intense diarrhea

It's borborygmi. The sound is produced when gas or liquid moves through the bowel. Peristalsis, the wave-like muscle tightening process that typically pushes food through the digestive system, produces the sound as it tries to push these substances through the body.

Feeding grazing cattle seaweed cut their methane emissions by almost 40%

The largest share of the 12% of global greenhouse gas emissions from livestock comes from methane released when cows burp. A study found that introducing a seaweed supplement in pellet form significantly reduced these emissions without affecting cattle's health or weight.

The benefits of extreme pain rituals, explained

We naturally avoid pain and see it as a negative experience. But many traditional cultures incorporate extremely painful rituals into their religious ceremonies, claiming they, in fact, provide ample benefits. Researchers were able to observe boosts in happiness and a sense of belonging in a tribe of Mauritians after they undertook a rigorously painful religious ritual. Read about the study here.

It is impossible for astronauts to burp in space

Due to Earth's gravity, liquids and solids sink in our digestive system, while gases rise, allowing them to be forced back up the esophagus to be expelled through burping. In the microgravity environment of the International Space Station, burping would result in vomiting if it were possible.

How fermentation enables the pickling of food and the production of beer

This process occurs when microbes produce lactic acid, ethanol, or carbon dioxide after consuming sugars. The acid helps preserve vegetables in a brine solution during pickling and gives them a sour taste, while ethanol serves as the inebriant in alcoholic beverages. The acid and carbon dioxide give sourdough bread its taste and texture.

Runners typically burn 2,600 calories during a marathon
