A new assessment of flood risk in Venice indicates that the impact of higher emissions on relative sea level rise during this century will be critical in planning future defense infrastructure for Venice and other coastal cities. The special issue, with contributions lead by researchers from Universita del Salento, ISMAR — Institute of Marine Sciences…

Using computer modeling, researchers simulated how the distribution of quaking aspen, a native tree known for its brilliant yellow and orange foliage in fall and the sound of its trembling leaves, will change amid rising temperatures over the next 100 years. Using computer modeling, researchers simulated how the distribution of quaking aspen, or Populus tremuloides,…

A researcher has made a discovery that alters our understanding of how the body’s DNA repair process works and may lead to new chemotherapy treatments for cancer and other disorders. Researchers discovered that base excision repair has a built-in mechanism to increase its effectiveness — it just needs to be captured at a very precise…

As the frequency and size of wildfires continues to increase worldwide, new research shows how the chemical aging of the particles emitted by these fires can lead to more extensive cloud formation and intense storm development in the atmosphere. «The introduction of large amounts of ice-nucleating particles from these fires can cause substantial impacts on…

Using observations from NASA’s ICON mission, scientists presented the first direct measurements of Earth’s long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It’s powered by tidal winds in the…

A new study adds a new layer to understanding how an oil spill could impact marine life. A diverse community of worms and other marine organisms on the seafloor plays a large role in nutrient cycling, organic matter burial, and remineralization. The burrowing and feeding activities of these organisms or bioturbation helps in the oxygenation…

A 17-year study in Oregon, Washington and California found that removal of invasive barred owls arrested the population decline of the northern spotted owl, a native species threatened by invading barred owls and the loss of old-forest habitats. The conservation and management of northern spotted owls became one of the largest and most visible wildlife…

Scientists have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea — regions where species richness, community stability and climate stability are high. Marine biodiversity, the diversity of life in the seas and oceans, supports ecosystem services of immense societal benefits. However, climate change and human activities…

A research group showed that gorilla APOBEC3G potentially plays a role in inhibiting SIVcpz replication. Intriguingly, the research group demonstrated that an amino acid substitution in SIVcpz Vif, M16E, is sufficient to overcome gorilla APOBEC3G-mediated restriction. To achieve cross-species transmission, new hosts have to be exposed to the virus from the old host. Next, the…

A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture. Now, research finds that solar geoengineering may be surprisingly effective in alleviating some of the worst impacts of global warming on crops.…
