Researchers found that severe asthma affects 2% of the population and is closely related to chronic rhinosinusitis and nasal blockage. Individuals with multiple asthma symptoms are likely to have a more severe form of asthma, increasing the risk of attacks and negatively impacting quality of life.
Researchers have isolated and observed the kinetochore, a molecular complex that pulls chromosomes apart during cell division, outside of cells. The kinetochore's precise mechanism involves a balance of tension and disassembly to ensure accurate DNA replication.
Two iron compounds have been synthesized to inhibit the growth of Mycobacterium tuberculosis in vitro. The compounds showed low toxicity in mammalian cells, making them promising candidates for treating tuberculosis and serving as hospital disinfectants.
Researchers found that mammal body size patterns changed dramatically after the dinosaurs went extinct. The study, funded by NSF, reveals a thousand-fold increase in mammalian body size over time.
The ATLAS experiment at CERN has directly observed lead ions melting and dissolving into smaller particles, providing insight into the universe's early stages. This phenomenon was only expected to occur at extreme temperatures, confirming the power of the LHC in studying fundamental physics.
Researchers have identified a key role for a protein called RyR2 in the development of long-term changes in brain connectivity associated with learning, memory, and addiction. By upregulating RyR2, nicotine can trigger the formation of new connections in the brain, leading to addictive behavior.
