Simon Fraser University researchers have found evidence that large raid-predatory worms – some up to two meters long – roamed the ocean floor near Taiwan more than 20 million years ago. The result, published today in the magazine Scientific reportsis the result of the reconstruction of an unusual trace fossil that they identified as the […]

Deep in the Brazilian Amazon Basin, scientists led by fish research fellow C. David de Santana of the Smithsonian National Museum of Natural History discovered a small, river-fed lake filled with more than 100 adult electric eels, many of which were over 4 years old Feet long. In itself, this was a fascinating discovery. Electric […]
Scientists Examine Salmonella Swimming Behavior as Indicative of Infection – ScienceDaily
Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) often cause gastroenteritis in humans, an inflammation of the intestinal lining. The bacteria live in the gut and can infect the epithelial cells that line its surface. Many studies have shown that salmonella uses a "run-and-tumble" method for short periods of swimming (runs) interrupted by falls when they […]

In diseases characterized by bone loss, such as periodontal disease, rheumatoid arthritis, and osteoporosis, there are a lot that scientists still don't understand. What role does the immune response play in this? What happens to the regulatory mechanisms that protect the bones? In a recent article in Scientific reportsResearchers at the Forsyth Institute and the […]
