Scientists have found the first ever evidence that tyrannosaur dinosaurs existed in the southern continents. They identified a hip bone found at Dinosaur Cove in Victoria, Australia, as belonging to an ancestor of Tyrannosaurus rex.

By enhancing the activity of immune cells that protect against runaway inflammation, researchers may have found a novel therapy for rheumatoid arthritis and other autoimmune diseases. Researchers now reveal how treating these immune cells with an investigational drug wards off inflammation by holding a particular enzyme at bay.

Researchers have found that even before infants begin to speak, words play an important role in their cognition. For 3-month-old infants, words influence performance in a cognitive task in a way that goes beyond the influence of other kinds of sounds, including musical tones.

Although they emerged more than 90 years apart, the influenza viruses responsible for the pandemics of 1918 and 2009 share a structural detail that makes both susceptible to neutralization by the same antibodies.

Fast food has become an industry that has widespread influence on what and how we eat. The original idea behind fast food is to increase efficiency, allowing people to quickly finish a meal so they can move on to other matters. Researchers, however, have found that the mere exposure to fast food and related symbols [...]

Supermassive black holes found at the centers of distant galaxies undergo huge growth spurts as a result of galactic collisions, according to a new study.
Scientists have used a novel cell-based strategy to treat motor symptoms in rats with a disease designed to mimic Parkinson’s disease. The strategy suggests a promising approach, the scientists say, for treating symptoms of Parkinson’s disease and other neurodegenerative diseases and disorders, including epilepsy.

Scientists have presented a design strategy to produce the long-sought artificial leaf, which could harness Mother Nature’s ability to produce energy from sunlight and water in the process called photosynthesis. The new recipe, based on the chemistry and biology of natural leaves, could lead to working prototypes of an artificial leaf that capture solar energy [...]

Researchers have discovered a fundamental step in the development of the immune system, one that allows B cells to mature and fight disease by producing effective antibodies. Immunologists have demonstrated that immature B cells in the bone marrow must receive a positive signal, mediated by the Erk protein, before they can migrate to the spleen [...]
