The findings may speed the search for drugs to block the most severe effects of COVID-19. |
| Scientists can predict which women will have serious pregnancy complications Posted: 08 Jun 2021 05:39 AM PDT Pregnancy disorders are usually diagnosed during the second or third trimester of gestation when they have often already had a serious impact on the health of the mother and baby. The current methods to diagnose pregnancy disorders are not sensitive or reliable enough to identify all at risk pregnancies. Now scientists have found a way to test hormone levels in the placenta to predict which women will have serious pregnancy complications. |

On the other hand, since dysregulation of UPR has been associated with various human diseases, the compounds modulating UPR can clarify the pathological significance of the UPR. |
| Posted: 07 Jun 2021 06:57 AM PDT To investigate the role genes play in the evolution of social structure, researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study revealed the same clones occupied the same social positions in each enclosure, regardless of living conditions, providing evidence that popularity is heritable. |
| Applying mathematics takes 'friendship paradox' beyond averages Posted: 07 Jun 2021 05:46 AM PDT In network science, the famous 'friendship paradox' describes why your friends are (on average) more popular, richer, and more attractive than you are.
