known as endocytosis and phagocytosis, in which extracellular material is captured by a pinched-in segment of the cell membrane. This extracellular material then becomes trapped inside the resulting membrane-bound intracellular compartment, which is ...

may be influenced by circadian rhythms. Auxin tells shoots to grow away from the ground and toward light and water. Charles Darwin conducted early experiments that showed how auxin affects plant growth. Most plants and animals have an internal cloc...
New system of wastewater treatment could reduce the size of treatment plants by half
...scientists from Granada have included a biological processes
section in their wastewater treatment plant, which could make it possible to separate water from active mud by a membrane filtration process. This researched and optimized system makes it possible to treat a larger flow of water in a smaller purifi...
New textbook illuminates the close links between evolutionary and molecular biology

of DNA and RNA copying during cell division. These are responsible for reading the genetic code and making sure it is encoded correctly in the daughter cell. In healthy cells it is important that this process works normally, but in cancer cells it is...
Tropical insects 'go the distance' to inform rainforest conservation

in maintaining tropical diversity, predicting species extinction and designing the systems of protected natural areas, Hulcr said. Because diversity doesnt necessarily increase with distance, but animals in small reserves tend to go extinct, you s...
1 of deep ocean's most turbulent areas has big impact on climate
... Oceanographers are working hard to understand how processes
in the ocean help to keep the Earths climate stable, St. Laurent said. We are aware that the climate is warming, but we dont yet fully understand how the changes will affect society. Our work will result in better models for predicting how the ocean ...
