The origin of a new species of Darwin's finches

Researchers from Princeton University and Uppsala University report the origin of a new lineage of Darwin's finches through hybridization between two distinct species. The study reveals that reproductive isolation was established in just two generations, with the new lineage becoming ecologically competitive and unique.

Biologists studied cellular cannibalism in cancerous growths

Researchers at Lomonosov Moscow State University discovered a new method of destroying cancer cells through a process called entosis, where one cell invades and digests another. The study reveals the five stages of entosis, which involves changes in structural and functional characteristics of both cells.

When magma prevents volcanic eruptions

Researchers from UNIGE and Roma Tre used thermal and experimental models to explain caldera resurgence, a process that prevents volcanic eruptions. The leftover magma behaves like a 'rubber sheet' due to its higher viscosity, stopping the new magma from reaching the surface.

To address hunger effectively, first check the weather, says new study

A new study suggests that understanding rainfall patterns is key to effectively addressing food insecurity among smallholder farms in Africa and Asia. Financial supports, such as cash or loans, were more frequently correlated with improved food security for drier farms, while agricultural inputs and practices were more effective for we...
