We usually assume that inbreeding is bad and should be avoided under all circumstances. But new research performed by researchers at Stockholm University, published in Nature Ecology and Evolution, shows that there is little support for this assumption. The idea that animals should avoid mating with relatives has been the starting point for hundreds of scientific studies performed among many species. But it turns out the picture is more complicated. "People assume that animals should avoid mating with a relative when given the chance", says Raïssa de Boer, researcher in zoology at Stockholm University. "But evolutionary theory has been telling us that animals should tolerate, or even prefer, mating with relatives under a broad range of conditions for more than four ...

A Wyss Institute-led collaboration spanning four research labs and hundreds of miles has used the Institute's organ-on-a-chip (Organ Chip) technology to identify the antimalarial drug amodiaquine as a potent inhibitor of infection with SARS-CoV-2, the virus that causes COVID-19. The Organ Chip-based drug testing ecosystem established by the collaboration greatly streamlines the process of evaluating the safety and efficacy of existing drugs for new medical applications, and provides a proof-of-concept for the use of Organ Chips to rapidly repurpose existing drugs for new medical applications, including future pandemics. The research is reported in Nature Biomedical Engineering. While many groups around the ...

Two of the most destructive forces of nature - earthquakes and tsunamis - might actually be more of a threat than current estimates according to new research conducted by scientists at The University of New Mexico and the Nanyang Technological University published today in Nature Geoscience. The researchers developed a new method to assess earthquake and tsunami hazards represented by the most distant part of offshore subduction zones and found that the hazard might have been systematically underestimated in some areas, meaning that tsunami risk assessments should be redone given the ...

A grass commonly used to fight soil erosion has been genetically modified to successfully remove toxic chemicals left in the ground from munitions that are dangerous to human health, new research shows. The study - led by the University of York- demonstrates that genetically modified switchgrass (Panicum virgatum) can detoxify residues of the military explosive, RDX, left behind on live-fire training ranges, munitions dumps and minefields. RDX has been a major component of munitions since WW2 which are still used extensively on military training grounds. This use has now resulted in widespread pollution of groundwater. Researchers generated the plants by inserting two genes from bacteria able to breakdown RDX. The plants were then grown in RDX contaminated ...
