The second part of the new IPCC report, about the impacts of climate change, has been released on Monday. Across the globe dutiful journalists filled the headlines of their newspapers – and as they presume most of their readers are … Continue reading →
Until now, we knew that ticks primarily transmit two pathogens to humans in Switzerland: the bacterium Borrelia burgdorferi – which causes borreliosis – and the early-summer-meningoencephalitis virus, which can cause cerebral inflammation.
Now, microbiologists from the University of Zurich confirm the existence of another tick disease in Switzerland – neoehrlichiosis.
Researchers who were looking for organisms that eke out a living in some of the most inhospitable soils on Earth have found a hardy few. A new DNA analysis of rocky soils in the martian-like landscape on some volcanoes in South America has revealed a handful of bacteria, fungi, and other rudimentary organisms, called archaea, which seem to have a different way of converting energy than their cousins elsewhere in the world.
The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans.
A collaboration between researchers at three universities in Sweden – Lund University, the Swedish University of Agricultural Sciences and Karolinska Institutet – has produced findings that could be a step towards solving the problems of both bee deaths and antibiotic resistance.
Before wastewater reaches recipient waters, nutrients must be removed in order to avoid eutrophication and large algal blooms, which may result in serious damage to animal and plant life. Robert Almstrand at the University of Gothenburg, Sweden, has shown in his thesis that better removal of nitrogen from wastewater can be achieved by providing the bacteria that purify the water with alternating high and low levels of nutrients.
Same story as yesterday, but now 635 million years earlier. This time again no evidence can be found that it were microbes that ate climate-disrupting amounts of methane, at the end of the Marinoan ice age, better known as ‘Snowball … Continue reading →
A group of 13 marine scientists* from 12 different institutions in the United States and Germany have in Science criticised a January publication in that same journal, which stated ‘almost all’ of the spilled methane had been consumed by microbes, … Continue reading →
Powerful convection in summertime thunderstorms explains why raindrops can become ‘trapped’ in the cumulus clouds, recycling the water at high altitudes, where temperatures are below zero – even today.
High fat diets are known to lead to obesity and other diseases. A new study in Nature shows how lipids are processed by the bacteria in the gut and can increase the risk for developing cardiovascular diseases. continue reading
Antibiotic resistant bacteria infections are on the rise. Numbers of MRSA (methicillin-resistant Staphylococcus aureus) cases are skyrocketing and ways to treat them are limited. By using the proteins expressed in the bacteria itself, scientists have found a new way to … Continue reading →
