Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin. This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA -- both within...

For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance has significant potential for modeling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation....

Until now, scientists were pretty sure they knew how the surface of a neutron star -- a super dense star that forms when a large star explodes and its core collapses into itself -- can heat itself up. However researchers rethinking that. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/V...

La interacción de diferentes especies que conviven y obtienen beneficios recíprocos, llevó a un grupo de investigadores del Cinvestav, unidad Irapuato, a estudiar este fenómeno conocido como mutualismo. En específico, el existente entre acacias y hormigas, pues estas últimas protegen al árbol con...

Black holes can be petite, with masses only about 10 times that of our sun -- or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black holes also come in size medium? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is busy scrutinizing a class of black holes that may...
