Several areas around the world may fall into this category, including the San Francisco Bay area, Izmit Bay in Turkey and the Gulf of Al-Aqaba in Egypt. |
| Mating with relatives? Not a big deal in nature Posted: 03 May 2021 11:47 AM PDT The idea that animals should avoid mating with relatives has been the starting point for hundreds of scientific studies performed among many species. But new research shows that there is little support for this assumption. The study provides a synthesis of 139 experimental studies in 88 species and 40 years of research, settling the debate about if and when animals should avoid inbreeding. |

However, these adverse effects were lessened in people taking nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin. The study is among the first to explore short-term air pollution exposures and the use of NSAIDs to mitigate their effects. |

| Less precipitation means less plant diversity Posted: 03 May 2021 07:48 AM PDT Water is a scarce resource in many of the Earth's ecosystems. This scarcity is likely to increase in the course of climate change. This, in turn, might lead to a considerable decline in plant diversity. Using experimental data from all over the world, a team of scientists have demonstrated for the first time that plant biodiversity in drylands is particularly sensitive to changes in precipitation. |

The findings can potentially provide tools for understanding and preventing aggressive behavior. |
| Tailor-made therapy of multi-resistant tuberculosis Posted: 03 May 2021 07:00 AM PDT The successful treatment of multidrug-resistant tuberculosis requires clarification in advance as to which antibiotics the pathogens are resistant to.
