| How bullying and obesity can affect girls' and boys' mental health Posted: 07 May 2021 08:20 AM PDT Depressive symptoms are more common in teenage girls than in their male peers. However, boys' mental health appears to be affected more if they suffer from obesity. Irrespective of gender, bullying is a considerably greater risk factor than overweight for developing depressive symptoms. |
| Protecting coral from heat stress and coral bleaching Posted: 07 May 2021 08:20 AM PDT Coral bleaching, which is becoming stronger and more frequent due to heat stress, has already wiped out corals at many locations globally. With the help of a microbiome-targeting strategy, it could become feasible to help protect corals from heat stress. |
| How we retrieve our knowledge about the world Posted: 07 May 2021 08:20 AM PDT In order to find our way in the world, we classify it into concepts, such as 'telephone'. Until now, it was unclear how the brain retrieves these when we only encounter the word and don't perceive the objects directly. Scientists have now developed a model of how the brain processes abstract knowledge. They found that depending on which features one concentrates on, the corresponding brain regions go into action. |
| Posted: 07 May 2021 06:39 AM PDT Informatics experts have developed a new computational model that demonstrates a long sought after link between insect and mammalian learning. |
