Children living in crowded homes exhibit poorer school performance and more frequent conflicts with parents compared to those from less crowded environments. Additionally, boys in crowded conditions show higher blood pressure, while girls feel more helpless than their male counterparts.
Cystic fibrosis damages young lungs due to chronic bacterial infections and a lack of liquid layer, which hinders the body's natural cleansing process. Researchers have discovered that the film of liquid coating airways is depleted in CF patients, preventing cilia from functioning properly.
Researchers at Carnegie Institution use X-ray diffraction to determine iron's elasticity at high pressures, which could explain seismic anisotropy in the inner core. The findings suggest the inner core is close to melting and may contain additional components with low shear-wave velocities.
Researchers link transplant tolerance to immune system's response to noncytopathic micro-organisms, which can coexist with transplanted organs. The process involves a delicate balancing act between donor and recipient immune cells.
Recent discoveries in circadian rhythms research have identified a set of probably a dozen or so proteins that regulate the biological clock in flies and mammals. These proteins share a common molecular motif called the PAS domain, which instructs them to attach to other proteins and help set the clock's time.
