A new study examines the symbiotic relationship between two types of bacteria and spittlebugs that helps the insect live on very low-nutrient food. The bacteria use a metabolic "trick" also employed by cancer cells to create the right conditions for converting the poor food into the necessary building blocks for survival.

Samuel Hulse, a Ph.D. candidate at UMBC, spent a lot of time in waders over the last two years. He traipsed from stream to stream across the eastern U.S., carefully collecting live specimens of small, colorful freshwater fish known as darters and taking photos of their habitats. Then he brought them back to the lab to capture high-quality images of their coloration patterns.

Monoclonal antibodies are those that originate from identical immune cells having a common origin. They are highly effective, non-toxic and can specifically target diseased cells, and are therefore used in immunotherapy to treat diseases such as psoriasis, cancer and autoimmune disorders. However, since antibodies are unable to cross the cell membrane, they have mainly been used against antigens present on the surface of cells.

Elephants ranged over Schöningen in Lower Saxony 300,000 years ago. In recent years, remains of at least ten elephants have been found at the Palaeolithic sites situated on the edges of the former opencast lignite mine. Now, archaeologists from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen, in cooperation with the Lower Saxony State Office for Heritage, have recovered for the first time in Schöningen an almost complete skeleton of […]

Grasslands across the globe, which support the majority of the world's grazing animals, have been transitioning to shrublands in a process that scientists call "woody plant encroachment."
