This breakthrough offers new hope for a potential cure for HIV by combining with existing treatments.

Dietary changes could produce big offsets to carbon emissions

Researchers found that producing animal-sourced foods consumes over 80% of the Earth's agricultural acreage, leading to widespread deforestation and climate change. Shifting to land-friendly diets could regrow native vegetation capable of absorbing CO2, reducing atmospheric carbon dioxide levels.

Volcanic ash may have a bigger impact on the climate than we thought

A new study suggests that volcanic ash can persist in the air for months after an eruption, potentially hastening the transformation of volcanic gases and darkening the planet. The discovery was made using real-world observations and advanced computer simulations of the Mount Kelut eruption on Java in 2014.

Innate immune system -- How cGAS is kept bottled up

The innate immune system interprets cytosolic DNA as a sign of intracellular pathogens. However, cGAS is found in the nucleus and prevents autoimmune reactions by binding to chromatin, not DNA. This interaction fails to activate the innate immune system.

How chemical diversity in plants facilitates plant-animal interactions

Researchers discovered a complex chemical system in the neotropical shrub Piper sancti-felicis that helps it balance attraction and repulsion from wildlife. The plant produces alkenylphenol compounds with antifungal properties, which protect its fruit from harmful fungi but also make it less appealing to seed dispersers like bats.
