Researchers have found that flowering plants have small cells relative to other major plant groups, made possible by a greatly reduced genome size, and this may explain how they became dominant so rapidly in ecosystems across the world.
Both the etiology and demographics of podoconiosis, a non-infectious disease which causes massive swelling of the legs, are poorly understood. To help contribute to the global atlas of podoconiosis knowledge, researchers have now described the distribution of podoconiosis in Cameroon.
As carbon dioxide (CO2) levels in the atmosphere rise, more CO2 gets absorbed into seawater. As a result, the world’s oceans have grown more acidic over time, causing a wide range of well-documented problems for marine animals and ecosystems. Now, researchers present some of the first evidence that similar things […]
Brain cells that reflect self position relative to others have been identified in the rat hippocampus. Sometimes these representations are processed jointly by the same cells, depending on a rat’s goals and actions. This discovery deepens our understanding of the hippocampus and its role as the brain’s positioning system.
Wireless headphones, two yo-yos connected by a string, earmuffs: all these items could be used to describe a tiny structure inside a cell’s nucleus. For decades, scientists could only speculate about the shape of heterochromatin, a type of chromatin — which consists of tightly packed DNA and proteins.
Researchers have found eight sites where thick deposits of ice beneath Mars’ surface are exposed in faces of eroding slopes. The ice was likely deposited as snow long ago. The deposits hold clues about Mars’ climate history and also may make frozen water more accessible than previously thought to future […]
Spotted owls and barred owls are being exposed to high levels of rat poison in northwest California, with illegal marijuana farms the most likely source point, according to a new study. Proposition 64, which legalized recreational marijuana in the state, went into effect this month and is expected to intensify […]
