Does Glyphosate Disturb the Human Gut Microbiome?
More than half the bacteria in the human gut microbiome are sensitive to glyphosate, the mostly commonly used herbicide in the world, reported scientists this month in the Journal of Hazardous Materials.
Researchers from the University of Turku in Finland recently developed a novel bioinformatics tool to predict if beneficial bacteria in the human gut are affected by exposure to glyphosate.
They found that the herbicide could disturb the natural cycles of microbiome life, and potentially harm human health, through weakening the system and causing greater susceptibility to diseases.
"Glyphosate targets an enzyme ... [that] is crucial to synthesizing three essential amino acids," said Pere Puigbò, who co-developed the bioinformatics tool.
Glyphosate is regularly in the news, viewed as a potential threat to health and well-being because of its widespread use on crops including corn, soy and canola. It is also a household weed killer, particularly the Monsanto/Bayer-owned brand Roundup.
The herbicide is currently banned from many countries including Germany, Saudi Arabia and Vietnam, and is heavily restricted in others. Cities and states across the U.S. are starting to reduce use or pushing for a ban, due to mounting health concerns. Other cities, such as Los Angeles and Miami, have already banned use.
"We need experimental research to study the effects of glyphosate on microbial communities in variable environments," said researcher Marjo Helander in a statement about the findings.
"This groundbreaking study provides tools for further studies to determine the actual impact of glyphosate on human and animal gut microbiota and thus to their health."

Earth had its second-warmest year on record in 2020, just 0.02 degrees Celsius (0.04°F) behind the record set in 2016, and 0.98 degrees Celsius (1.76°F) above the 20th-century average, NOAA reported January 14.
Figure 1. Departure of temperature from average for 2020, the second-warmest year the globe has seen since record-keeping began in 1880, according to NOAA. Record-high annual temperatures over land and ocean surfaces were measured across parts of Europe, Asia, southern North America, South America, and across parts of the Atlantic, Indian, and Pacific oceans. No land or ocean areas were record cold for the year. NOAA National Centers for Environmental Information

In December of 1924, the heads of all the major lightbulb manufacturers across the world met in Geneva to concoct a sinister plan. Their talks outlined limits on how long all of their lightbulbs would last. The idea is that if their bulbs failed quickly customers would have to buy more of their product. In this video, we're going to unpack this idea of purposefully creating inferior products to drive sales, a symptom of late-stage capitalism that has since been coined planned obsolescence. And as we'll see, this obsolescence can have drastic consequences on our wallets, waste streams, and even our climate.
