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 »

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 »

Clay to Fight Bacteria in Wounds: An old practice may be a new solution

ROCHESTER, Minn. – The use of mud or wet clay as a topical skin treatment or a poultice is a common practice in some cultures and the concept of using mud as medicine goes back to earliest times. Now Mayo Clinic researchers and their collaborators at Arizona State University have found that at least one type of clay may help fight… Read more »

Gut Bacteria Hold the Key to Creating Universal Blood

In January, raging storms caused medical emergencies along the U.S. East Coast, prompting the Red Cross to issue an urgent call for blood donations. The nation’s blood supply was especially in need of O-type blood that can be universally administered in an emergency. Now, scientists say they have identified enzymes — from the human gut — that can turn type… Read more »

We zijn niet lief genoeg voor onze bacteriën

      Geen reacties op We zijn niet lief genoeg voor onze bacteriën

Terwijl we proberen schoon te blijven door goed alle bacteriën van ons af te wassen, vernietigen we eigenlijk vooral ons eigen verdedigingsleger aan vriendelijke bacteriën. Hoog tijd dat er producten komen die rekening houden met ons huideigen huisdiertjes en die ze zelfs kunnen helpen herstellen als het slecht met ze gaat.
