An imaging method that reveals a much more diverse and flexible DNA-protein chromatin chain than previously thought has now been developed by researchers. The result suggests a nimbler structure to regulate gene expression, and provide a mechanism for chemical modifications of DNA to be maintained as cells divide.
A breakthrough has been made in the area of material design -- one that challenges the commonly held view on how the fundamental building blocks of matter come together. Scientists have shown that the granular building blocks in copper can never fit together perfectly, but are rotated causing an unexpected level of surface roughness. This behavior, previously undetected, will have important implications for how materials are designed.
Up to half of the matter in our Milky Way galaxy may come from distant galaxies, astrophysicists have discovered in a first-of-its-kind analysis. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, the researchers found an unexpected mode for how galaxies acquired matter: intergalactic transfer. Supernova explosions eject copious amounts of gas from galaxies, causing atoms to be transported from one galaxy to another via powerful galactic winds.
Two gut pathogens commonly found in malnourished children combine to worsen malnutrition and impair growth in laboratory mice, according to new research.
By omitting mechanistic drivers such as sunlight, a statistical theory accurately describes broad ecological patterns in a Panama forest, as well as other natural systems and communities.
Skin transplant surgery has long-term benefit for restoring skin pigmentation caused by the skin disease vitiligo, new research shows. In a retrospective study, researchers found that a majority of areas of the skin treated with surgery still had 'very good to excellent' color match pigmentation five years later.
A cluster of nerve cells in the male mouse's brain have been identified that, when activated, triggers territorial rage in a variety of situations. Activating the same cluster has no such effect on female mice.
Масса бозона Хиггса — это последний параметр Стандартной модели, который не был известен до запуска LHC. «Взвешивают» бозон Хиггса, конечно, не напрямую, а косвенно, по положению хиггсовского пика в тех каналах распада, в которых удается поймать все частицы-продукты распада. Пока что это только два канала — двухфотонный и распад на ZZ-пару, которая дальше распадается на лептоны.
