An article published in the magazine “Geophysical Research Letters” describes a research that offers a new estimate of the climate changes caused by the meteorite that about 66 million years ago led to the extinction of dinosaurs and a lot of other species of the time. According to a team of researchers the amount of sulfur released in the atmosphere was greater than the previous estimates with worse consequences. Part of the authors also participated in drills into the crater caused by the meteorite, which results are described in an article published in the magazine “GSA Today”.

Some environments in which microbes were sampled

An article published in the journal “Nature” presents a meta-analysis of microbial samples collected by hundreds of researchers from the Earth Microbiome Project (EMP), which pursues a systematic globally attempt to classify microbes. The researchers established protocols and new analytical methods to manage the results of genetic sequencing of bacteria and archaea in multiple studies. Our knowledge of these microorganisms remains limited but this project will allow to expand them and better understand their impact on the ecosystems they’re part of.
