Turning sweat against itself with a metal-free antiperspirant

Added: 15.01.2021 1:19 | 4 views | 0 comments

Body odor is an unpleasant smell, produced when bacteria living on the skin break down the proteins in sweat. To avoid stinking, some people apply antiperspirants that clog sweat ducts with foreign materials, such as metals, to slow perspiration. As a step toward a more natural solution, researchers have turned sweat against itself using an evaporation-based approach in which the salts in sweat create a gel-like plug.

A gene from ancient bacteria helps ticks spread Lyme disease

Added: 15.01.2021 1:19 | 4 views | 0 comments

One reason ticks spread Lyme disease so well goes back to a unique evolutionary event. Researchers discovered that an antibacterial enzyme in ticks, Dae2, protects them from bacteria found on human skin, while still allowing them to harbor Borrelia burgdorferi, the bacterium that causes Lyme disease. Ticks acquired the gene for this enzyme 40 million years ago from an unknown species of ancient bacteria.

Greenland melting likely increased by bacteria in sediment

Added: 15.01.2021 1:18 | 15 views | 0 comments

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island's contribution to sea-level rise, according to scientists. That's because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to new study. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.

Feces and algorithms: Artificial Intelligence to map our intestinal bacteria

Added: 15.01.2021 0:18 | 19 views | 0 comments

The intestines and their bacteria are sometimes called our 'second brain', but studying these bacteria in their natural environment is difficult. Now researchers have developed a method that uses artificial intelligence to map intestinal bacteria using feces. The researchers thus hope to gain more knowledge of the role played by these bacteria in various diseases.

Scientists study salmonella swimming behavior as clues to infection

Added: 14.01.2021 0:18 | 26 views | 0 comments

Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) commonly cause human gastroenteritis, inflammation of the lining of the intestines. The bacteria live inside the gut and can infect the epithelial cells that line its surface. Many studies have shown that Salmonella use a 'run-and-tumble' method of short swimming periods (runs) punctuated by tumbles when they randomly change direction, but how they move within the gut is not well understood.
