We zijn schoner dan ooit. Te schoon, misschien

Uit een artikel van Trouw “We zijn schoner dan ooit. Te schoon, misschien” Als gezonde mensen gezond willen blijven, hebben ze juist contact nodig met allerlei verschillende soorten microben, zegt Smits: “Als we voldoende signalen krijgen van micro-organismen om ons heen, wordt ons afweersysteem opgevoed. Daardoor kan het een beter onderscheid maken tussen signalen die lichaamseigen en lichaamsvreemd zijn, en… Read more »

Bijen sterven sneller door omstreden onkruidverdelger glyfosaat

De meest gebruikte onkruidverdelger ter wereld beschadigt gezonde bacteriën in de ingewanden van honingbijen en maakt ze vatbaarder voor dodelijke infecties. Dat heeft nieuw onderzoek aangetoond. Eerdere studies hebben aangetoond dat pesticiden zoals neonicotinoïden schadelijk zijn voor bijen, waarvan de bestuiving essentieel is voor ongeveer driekwart van alle voedselgewassen. Glyfosaat, het meest gebruikte onkruidbestrijdingsmiddel ooit en vervaardigd door Monsanto, richt zich op een enzym… Read more »

Fast and hardwired: Gut-brain connection could lead to a “new sense”

The mysteries of our “second brain” are a profound new frontier in 21st century medical science. While research is rapidly discovering amazing connections between our gut and our brain, little is known about how these two distinct parts of the body communicate with each other. A remarkable new study has upturned existing ideas surrounding gut-brain communication, revealing a fast-acting neural circuit… Read more »

There are more microbial species on Earth than stars in the galaxy

For centuries, humans have endeavoured to discover and describe the sum of Earth’s biological diversity. Scientists and naturalists have catalogued species from all continents and oceans, from the depths of Earth’s crust to the highest mountains, and from the most remote jungles to our most populated cities. This grand effort sheds light on the forms and behaviours that evolution has… Read more »

Gut Bacteria Can Produce Electricity

      Geen reacties op Gut Bacteria Can Produce Electricity

Researchers have discovered that bacteria that are part of the human gut microbiome have the ability to produce electricity, using techniques that differ from known electrogenic bacteria. Scientists from the University of California Berkeley have found that Listeria monocytogenes and hundreds of other bacterial species produce electricity, a discovery that could yield living batteries from microbes. “The fact that so many bugs… Read more »

Revolutions is our new series that brings together a hand-picked selection of recent articles canvassing cutting-edge insights into major scientific advances. This first rundown brings you up to date with the ground-breaking science surrounding our gut microbiome. It’s striking to realize, but living inside all of us are trillions of micro-organisms. The vast majority of these tiny hitchhikers inhabit our… Read more »

A Scientist Explains Why Mosquitoes Bite Some People More Than Others

Surprisingly few of the more than 3,000 mosquito species actually specialise in biting humans. Instead, most are opportunistic feeders – feeding when they are able and from lots of different sources. But Aedes aegypti and Anopheles gambiae are well known for their preference for human blood and their role as vectors which transmit disease in humans. Ae. aegypti has been… Read more »
