A living thing that is too small to see with the unaided eye, including bacteria, some fungi and many other organisms such as amoebas. Most consist of a single cell. Scientists who study microbes and the infections they can cause or ways that they can interact with their environment are known as microbiologists.
It takes a microscope to view objects this small, such as bacteria or other one-celled organisms. Since its founding, SSP has been not only promoting public engagement in scientific research but also the public understanding of science.

It created and continues to run three renowned science competitions: SSP also publishes award-winning journalism: Those magazines also host a series of blogs including Eureka! It's a species of bacteria that is responsible for a number of serious human infections. It can cause surface abscesses, or boils.
If it gets into the bloodstream, where it can be carried throughout the body, it may also cause pneumonia and infections of the joints or bones. Wear and tear on tires, brake pads and road surfaces leaves harmful microplastics swirling in the air, a new study finds. Symbion pandora left is a tiny animal that lives on the mouth whiskers of lobsters.
Hairs around the belly button, they think, operate as a "one-way ratchet mechanism", stealing tiny fibres from inside your clothes and depositing them into your navel.

Pandora lives on only the Norway lobster right. At least two other Symbion species reside on other lobsters. Freshwater makes up just a tiny percent of the water on Earth. Yet we depend on it for everything from growing food to manufacturing to everyday uses at home. The averge American uses liters 90 gallons per day.
Most cars and trucks burn fossil fuels, which produce carbon dioxide and contribute to climate change. Wombats are stout marsupials native to Australia. They use their cubelike droppings to mark their territory. Skip to main content. Lab Scientists Say Analyze This! Which bacteria hang out in belly buttons? The second is that navel fluff forms more often in middle-aged, hairy men, especially ones who have recently put on weight.
These are the findings of a University of Sydney researcher named Karl Kruszelnicki. Dr Karl, as his fans know him, has an Australian science radio show, and one of his listeners wrote in asking where navel fluff comes from and how it forms. That inspired Kruszelnicki to distribute a survey online, which led him to the conclusion that BBL is an affliction mainly of middle-aged men with sufficient body hair. For his research, Kruszelnicki received an Ig Nobel Prize in , an accolade given for research that "first makes you laugh, and then makes you think.
View image of Credit: In addition to the online survey, Kruszelnicki and his colleagues collected samples from willing volunteers and also asked some to shave the hair from around their belly buttons. It turned out that shaving belly hair indeed prevented the accumulation of lint. While perhaps not the world's leading experts on the topic, Dr Karl and his colleagues arrived at an explanation for the formation of navel fluff that, at least, makes intuitive sense.
Hairs around the belly button, they think, operate as a "one-way ratchet mechanism", stealing tiny fibres from inside your clothes and depositing them into your navel.
Older clothes, less lint Kruszelnicki wasn't the only person to take a stab at what forms the fluff that fills belly buttons around the world. In , a Vienna University of Technology researcher named Georg Steinhauser published his hypothesis in the eyebrow-raising journal Medical Hypotheses. For reasons known only to himself, Steinhauser collected his own navel fluff each evening for three years.
Though he insists that he maintains good personal hygiene, including a shower each morning, his navel invariably becomes filled with fluff by the day's end. In all Steinhauser collected samples from his own belly button. Their combined weight didn't even reach a single gram. On average, a single piece had a mass of 1.
The hair itself scrapes tiny fibres off of a shirt, and then directs the lint towards the navel where it accumulates.
