It takes more than two to tango: Microbial communities influence animal sex and reproduction

It is an awkward idea, but a couple’s ability to have kids may partly depend on who else is present. The reproductive tracts of males and females contain whole communities of micro-organisms. These microbes can have considerable impact on (animal) fertility and reproduction. They may even lead to new species.

Did phosphorus-rich lakes help kickstart life on Earth?

The building blocks of life as we know it require chemical reactions involving phosphorus. But phosphorus is scarce on Earth. Where did enough of it come from to fuel life’s start? Carbonate-rich lakes, like Mono Lake in California, might hold a clue.

Cyanobacteria in water and on land identified as source of methane

(Forschungsverbund Berlin) Cyanobacteria, also known as blue-green algae, are among the most common organisms on Earth. A research team led by the Leibniz-Institute of Freshwater Ecology and Inland Fisheries and Heidelberg University has now shown for the first time that Cyanobacteria produce relevant amounts of methane in oceans, inland waters and on land. Due to climate change, “Cyanobacteria blooms” increase in frequency and extent, amplifying the release of methane from inland waters and oceans to the atmosphere.

Antibiotic tolerance reduces the ability to prevent resistance under drug combination therapies

(American Association for the Advancement of Science) Antimicrobial tolerance can promote the evolution of antimicrobial resistance even under combination drug treatments widely used and expected to prevent it from occurring, a new study finds.

Persistence of gut microbial strains in twins, living apart after cohabitating for decades

Using a genomics strain-tracking bioinformatics tool, researchers investigated whether shared bacterial strains remain stable and resilient to changes in diet or environment after adult twins — who had lived together for decades — began to live apart. The study analyzed two metagenomic sequencing databases from pairs of twins — one for children who were still living together and the other from adult twins, ages 36 to 80, who then lived apart for periods from one to 59 years.

Birds and bats have strange gut bacteria, and it might help them fly

We humans are relatively obsessed with the state of our gut bacteria. We have somewhere between 300 to 500 types of bacteria living in our digestive system, reports WebMD. Known as the microbiota, or the microbiome, research shows they impact…

Birds and bats have strange gut microbiomes — probably because they can fly

(Field Museum) Gut bacteria help us fight disease and digest food, but not all animals rely on their microbiomes the way we do. A new study comparing the guts of mammals, birds, reptiles, and amphibians shows that birds and bats have unusual microbiomes — probably because they both can fly.

Climate change: The devastation of Australia’s ocean – The Independent

Even before the ocean caught a fever and reached temperatures no one had ever seen, Australia’s ancient giant kelp was cooked. Rodney Dillon noticed it the day he squeezed into a wet suit several years ago and dove into Trumpeter…
