Salmon evolve quickly as a response to intense harvesting of their prey
No full textTo persist in the face of climate change and human activities, organisms may need to adapt. We showed that Atlantic salmon from River Teno (between Finland & Norway) evolved over the last 40 years to mature earlier. Our data suggest it was due to indirect and direct effects of fishing: harvesting of capelin to feed farmed animals, and size selective net fishing in the river
Prickly prospects for cacti under climate change
No full textThe common perception of cacti as heat- and drought-loving desert plants causes climate change to be overlooked as a potential threat to their conservation. Our work forecasting the distribution of cacti under various climate change scenarios reveals that a majority of species will lose suitable habitat. This discovery adds to a long list of factors threatening cacti
Agriculture and climate change driving worldwide insect declines
No full textInsects are a key part of the earth’s life support system, making reports of steep declines a great concern. Our study, one of the largest assessments of insect biodiversity to date, identifies climate change and intensive agriculture as key drivers of declines. We show that declines are most profound when these drivers are combined, but that preserving natural habitat can protect against loss
Gut microbiota drive anti-viral immunity
No full textWe investigated how the gut microbiota modulate anti-viral immunity in mouse models of infection. We showed that gut bacteria are vital for the presence of low level of type-I interferons, key mediators in anti-viral immunity. The gut bacteria deliver DNA in vesicles to host cells, priming anti-viral immunity
Fish identify themselves in mirrors and portraits
No full textCleaner fish can recognize cognitively their own images in mirrors and portraits as themselves via self-face recognition. For recognition of the self, they have an internal mental image of self-face like humans. This process suggests they have private self-awareness or “mind” and a concept of the self
Vikings and Migrants: Unravelling Scandinavia\u27s Genetic Mosaic in the Viking Era
No full textWe analysed ancient Scandinavian genomes over 2,000 years, revealing Viking-era influx from southern Europe, British-Irish Isles, and the east Baltic. Genetic diversity increased during that time, but later Scandinavians have less non-local ancestry. Uralic ancestry found 1,000 years ago still impacts northern Scandinavians
What keeps trees grounded?
No full textWhile exploring the root cause of trees\u27 gravity sensing, the Morita lab stumbled upon proteins called ‘LAZY’ and dissected their association with the starch-filled packets in roots to dissolve a long-standing dilemma – is gravity sensed in terms of the force that the heavy starch-filled packets exert on the cell content or is it their position that send signals dictating where the Earth is
