5,000 years of history of domestic cats in Central Europe

(Nicolaus Copernicus University in Torun) The history of human and cat relationships began 10,000 years ago. Its origins, however, still remain a mystery mainly due to scarcity of research material. Gaps in our knowledge in the subject are successfully filled by a group of researchers from the Nicolaus Copernicus University in Toru?. Dr Magdalena Krajcarz has made an attempt to find ancestors of domestic cats in Neolithic Central Europe. An article discussing the topic has recently been published in PNAS.

Safer CRISPR gene editing with fewer off-target hits

The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing ”off-target” sites. However, a new study shows that mutating the enzyme at the heart of the CRISPR gene editing system can improve its fidelity.

Scientists urge caution, further assessment of ecological impacts above deep sea mining

A new study argues that deep-sea mining poses significant risks, not only to the area immediately surrounding mining operations but also to the water hundreds to thousands of feet above the seafloor, threatening vast midwater ecosystems. Further, the scientists suggest how these risks could be evaluated more comprehensively to enable society and managers to decide if and how deep-sea mining should proceed.
